hot pot is a great solar cooker, but was designed for the tropics

by:Earlston     2019-12-10
In order for the hot pot to have practical use in the temperate zone, I find it essential to design and build a base powered by a solar DC motor, which faithfully tracks the sun from morning to afternoon, and tilt, as the height of the sun rises and falls in the day, to concentrate the sun.
Like all solar cookers, hot pot can concentrate and absorb ultraviolet rays (ultraviolet)
Radiation from the sun, which is converted to IR Inside (infrared)
Radiation for cooking
Moreover, since the area of the hotpot reflector is relatively small, everything must be carefully designed and fine-
Adjusted to work normally.
The core of the device is Dayton 2L004 type parallel shaft permanent magnet DC gear motor.
The 1634: 1 gearbox is driven by power up to 12VDC, turning its shaft with a diameter of 5/16 in a slow and controllable 1.
The rotation speed is 5 RPM at load and the torque is 46 inch/pounds.
Although the drive motor (a Mabuchi RF-500TB-12560)
Designed to run on 12VDC, 0.
The voltage range of 30 amps is actually 1. 5 -12 Volts.
And power the tracker, a small 6.
3VDC, 120 mA solar panels, 3. 125\" x 4. 25\" (80mm x 110mm)
, For 1/900 horsepower motor, reliable and easy, no-load 1. 7 RPM.
Unlike other Dayton 12VDC deceleration motors, this motor must be designed to be powered by relatively weak solar panels such as 6. 3VDC mono-
The crystal solar panel installed on the forward side of the reflector of the hot pot solar stove will be in the absence
Even if the panel is turned off and backed by the sun, this is the case with the load, because the motor is running at a speed of only 20 mA.
In fact, a much smaller one ,(55mm x 55mm)solar panel, 2.
5 V, 85 mA, also running Dayton gear motor under no load 0. 5 RPM.
In contrast, 12 volt, 5 amp batteries run Dayton gear motors at no-load 3. 3 RPM.
With its 1634: 1 gear ratio, the electronic circuit controller is not required because the motor is easy to activate and advance the solar reflector of the hot pot to faithfully track the sun. The 6.
3 VDC solar panels are mounted on the propulsion side of the reflector, perpendicular to the sun.
I also added a 3. 25\" (83mm)
Deep corrugated cardboard all around, jet-
Black interior to block stray sunlight that sometimes causes the reflector to go too far in advance. The north-
The southern end of the plane-
Black corrugated cardboard expansion out of 0. 5\" (13mm)
Because the timing wheel is round (
My original plan is called a more complex elliptical timing disk)
To compensate for the tilt of 10: 30 a. m. and 1: 30 p. m. almost 5 °.
The center of the solar panel is 5.
5 \"from the edge of the flat reflector base, 3\" forward from the center of the flat reflector base.
Of course, solar panels are adjusted as needed. The 6.
3 VDC solar panels are mounted on the arrow shaft of 5/16 and inserted tightly into the I of 5/16D.
Brass tube, allowing quick adjustment.
1 pound (450g)
, The deceleration motor provides a ballast that is very much needed to stabilize the reflector from shaking the wind.
Dayton, maker of Dayton 2L004 type parallel axis permanent magnet DC gear motor, was acquired by Grainger, who continues to offer Dayton lines in their name.
You can also buy a deceleration motor for about $70. 00 (
Including freight), from Amazon.
Com: actually got four of them at a yard sale for $1.
00, I can blame myself for not buying all 20 2L004 gear motors.
There are four mounting screws in the 2L004 gearbox, all standard 10-32 threads.
But install the motor/gearbox parallel to the plywoodo-
Gram, I removed all 4 screws, be careful not to let the gears fall off, then drill out 3 holes and knock 10-
32 threads, but strangely, the fourth hole is already 10-
32 lines of the factory
And then four 10-32 thread flat-head screws (1\" long)
Sink and rinse
Installed on 5mm plywood.
My plan is to have five round plywood timing plates 5mm thick. Living at 37.
76 ° latitude, after the experiment, I decided to set up a timing plate for the following noon sun height: 65 °, 67 °. 5°, 70°, 72.
5 ° and 75 °, because solar cooking with hot pot on days when the sun angle is less than 70 ° at noon is not worth it, unless the weather forecast for that day is unusually hot.
I will experience the maximum sun height of 76 ° in my area and 65 ° is set to the lowest noon sun height worth cooking.
Each tracking timing disk will start from about 4. 5\" to about 5. 25\" diameter (
If there is any change)
, Will allow pan and tilt of the hotpot reflector and follow the sun.
On the router, each disk is carefully ground into a perfect circle, and the circumference will be accepted black rubber o-by hollow slots-
Round cross ring \"tire\" with 1/8 \"-section.
The circumference of each tracking timing disc is determined by the extent of the sun orientation scan, from 10: 00 in the morning to 4: 00 in the afternoon, for a specific day at noon sun height (65°, 67. 5°, 70°, 72. 5°, or 75°)
, And use 5.
34 \"radius arc stroke is 11.
Tracking base with diameter of 75.
To mount the plywood tracking disc to the 5/16 \"DC gear motor shaft, I weld the 5/16\" Allen set screw steel collar to 1-
5/8 diameter steel gasket, drilling and counter
Insert four screw holes and install the easy fitting onto the disc with a flat surface
Wood screws.
Keep the timing plate on track and keep it fast in the wind of the thurser, ballast, weight 4. 5 ounces (130 grams)
Added to the center of the disk and projected 4. 125\" (10. 3 cm).
In such a position, the hot pot reflector will be more stable in the breeze without applying heavy objects on the gear motor drive.
Unfortunately, the eccentric cam action is combined with the ballast, resulting in excessive resistance when disengagedCenter tracking.
To greatly reduce this resistance, the wheel with a diameter of 28mm (
Toy car with rubber tires 5/8 wide)
Directly on the 11 th.
75 \"diameter plywood tracking base, located under the pivot of the timing plate, on the hinge arm of the lower lazy
Susan base, remove the resistance to the upward tilt.
It works well, although the entire parallelogram mechanism must be increased by 28mm to keep the hot pot reflector tracked at the best 65 ° sun angle.
It doesn\'t matter if the wheel diameter is 28mm, it\'s just what I found and used, the rolling resistance is minimal, keeping the shape of the hot pot Sun stove low enough to gain a foothold in the wind and grass.
I actually replaced 28mm rounds with a stronger 40mm (1-9/16\")
The diameter of the wheel and will improve the whole parallelo-
The gram mechanism of compensation is 40mm.
Earlier I posted the clear oven baking bag cover in error (
Details for next step)
Somehow I changed the optimal sun angle of the reflector from 65 to 55, but later found that the afternoon sun reflected my light
The gray cement driveway, bathed with mirrors in the intense sun, causes the hot pot to heat to the hottest temperature of the day.
I just wanted to post this correction.
Therefore, the optimal sun angle of the hot pot reflector is still maintained at 65 °.
After successfully trying several sizes of timed discs, I plan to redesign the pan and tilt mechanisms throughout the season (yet again)
Only one elliptical disc, designed for 85 ° high-
Noon sun angle mounted on a stretchable but locked arm, gradually marked as High
The midday sun angle of 60 ° to 85 ° allows for more flexibility and greater ease of use.
In addition, for those days and latitudes with low sun angles, a larger diameter tracking base is required to accommodate the extended locking arm. Stay posted.
On a given day, the solar powered DC deceleration motor shaft/timing disc rotates about 324 ° in 6 hours.
However, the hot pot reflector needs to aim at a much higher target at noon than at 10: 00 in the morning or 4: 00 in the afternoon.
In order to achieve this goal,
The plywood timing plate is drilled into the center shaft.
This disk design enables the pivot base to track the morning and afternoon sun and tilt the reflector completely to the sun.
At noon in the sun, the timing wheel pivot will be at the highest point, turning the reflector 1. 75x to 4.
33 times faster than 9: 00 in the morning or 3: 00 in the afternoon, and lower the inclined reflector to a more horizontal posture.
The exact position of the timing disc pivot is determined by drawing the Sun\'s overhead speed at noon and comparing it with the sun trip at 9: 00 in the morning or 3: 00 in the afternoon (
These two are always the same).
As described just now, the original timing disk was designed for the windup clock drive, but the details of the timing disk will be released soon, slightly re-
Designed for solar-powered geared motor drives.
DC deceleration motor driver with timing disc mounted on simple hinge parallelo-gram, 4. 75\", top-to-bottom, and 5. 125\" span.
For those of you who don\'t want to bother to build this sun-tracking mechanism, without it, a simple parallelogram pan and tilt base works fine.
Built with two \"lazy people-Susan bases (ball bearing)
10 small hinges, everything is turned on the standard 3/8 threaded rod.
Adding the deceleration motor tracking device later should be a good platform as going out every other hour or so, adjusting the hot pot reflector makes it easy to monopolize the day. A 11.
75 \"diameter plywood tray is used as a tracking base, marked in degrees, with a total maximum scan volume of 180 °, where the timing plate is carefully set in a specific orientation at 9: 00 a. m (
But it can also start later)
Start the solar cooking process.
Within my scope, the agency will do a 140 ° scan (
Sun corner day at 65 noon)
163 scan (
Sun corner day at 75 noon).
Due to my hot pot DC electric tracker/oven baking bag solar cooking unit is designed for over high cooking temperature, 11.
75 \"diameter plywood base will also be used for temperature adjustment: just lift the tracking timing plate and re-adjust it
Positioning it forward about 10 degrees will tilt the vertical tracking angle and effectively position the reflector slightly outside direct sunlight, so that it can reduce the cooking temperature of hot pot easily, accurately and in a controlled way.
In order to facilitate the setting and accurate positioning of the timing wheel, 3-
Position, \"forward-Off-
Reverse \"DPDT electrical switch (275 of Radio Shack-664)
Install and connect directly below the sun-
Facing the edge of the solar panel.
This simplifies the setting of the hotpot pot: remove the solar panel from the holder, which can withstand the sun and advance paymentOff-
Start the reverse switch, turn the timing disk to the noon high point position, and then set the switch to the \"off\" position.
The timing plate is then lifted and moved to a position 270 ° high at noon (
40mm rounds will follow automatically)
, The shaft of the 40mm wheel directly exceeds the 270 ° mark on 11.
Tracking base with diameter of 75.
Again, lift the solar panel to the Sun, start the \"reverse\" switch, slowly turn the hot pot reflector into the morning sun, and then turn off when aligned and positioned with the morning sun at the correct angle.
This can be done by standing behind the hotpot reflector and using \"forward-Off-
Reverse the \"electrical switch, turn the reflector until the sun, the reflector and its shadow are aligned and switch to the\" off \"position.
But in fact, simply align the reflector through the sun to the point where the sun-
The Motor brings itself back to the right route.
Then put the solar panel back in the bracket, switch to the \"forward\" position and start to track the sun automatically.
If, later in the day, an unusually strong wind blows the hot pot reflector up and out aligned, then it will re-locate again from the reference position of 270 high at noon, then push or reverse into the correct alignment of the sun.
I found this method to be much faster and more reliable than the initial confusing reference mark I recorded on the timing disk.
The rotating and tilting base of the hot pot reflector has a deep slot of 19 \"long x 1/8\" wide x 1/8 \"for the center hinge of the aluminum reflector base, for quick determination of accurate positioning, and four wide
The head aluminum screw holds the reflector in the proper position as it will be steep and will remain fast in strong winds as well.
To initially reduce the cost of the tracker, I tried using gears/generators but failed

Even with all these deceleration gears, it still doesn\'t have enough deceleration.
Even if the tiny generator/motor is high by the small 3VDC-
The torque motor that was salvaged from the old VCR camera, but at noon, which was quickly tilted up, it still tends to stop.
But I would suggest looking at another note with a simple capacitor --
Based on the circuit board, if combined with the LED flashlight gearbox and the \"motor\" it should provide enough intermittent torque to do the job: I also tried Intermatic™6-
Hourly Wall timer, FD6H type, windup clock driver.
While it works perfectly on my workbench, it can\'t withstand strong winds in an outdoor setting.
Also, when I converted the hot pot to a solar gear motor drive, I found the lower lazy-
Susan base has been contaminated with dirt and sand in the air and is no longer spinning freely, which completely explains the problem of getting the original clock drive mechanism to work properly during the outdoor testing phase.
I cleaned up and down the lazy lubrication ball bearings-
Susan lubricate them with a solvent and then with an aerosol graphite lubricant commonly used to lock the mechanism.
As a further precaution, a pipe cleaner is loosely tied around the upper and lower lazy people
Susan base to prevent further pollution.
Like the original in-room test, the tracker is now free to rotate.
It is also important for you experimenters to note that these interactions™Clock timers are now in short supply due to time intervals™The site doesn\'t seem to run anymore and the hardware store doesn\'t store these reliable and good products anymoremade devices.

The hour is by car and will make more attempts to finally get it to work.
Call me sentimental
But this DC motor
In temperate zones, the drive tracker is still not enough for solar cooking as a transparent plastic oven baking bag needs to cover the reflector in order to bring the hot pot to the appropriate cooking temperature quickly and reliably.
Hot pot, full, 3 heavy
4 quart of water or food, placed on the top of the 3/8 threaded rod, completely static and stable throughout the process, as everything, the reflector and everything revolves around it.
For more information about oven baking bags, see the next part of this manual.
As mentioned earlier, in order to play a role in the temperate zone, the hot pot reflector needs to be covered with a transparent plastic oven baking bag.
In my latitude (37. 76°)
Need one because hot pot is too unpredictable and unreliable without it.
The transparent plastic oven baking bag is designed to stay at an oven temperature of up to 400 degrees Fahrenheit, but the temperature in the hot pot reflection area will never be that high.
Only time can tell us the time of direct sunlight.
First oven burn bag test, I bought Renault®A Turkish-sized oven baking bag, two in a box, 19 \"x 23. 5\" (482mm x 596mm).
Both bags are sewn to 38 \"x 23\" and then glued together with transparent tape to form 38 \"x 46\" pieces.
The hot pot mirror is completely covered by the oven baking bag and pasted with adhesive tape. The effect is good.
But after Renault®Oven baking bag on my hinge wood rack and try a second trial run (see below)
, I was not satisfied with the result and removed the oven baking bag cover from the wooden frame.
Renault hotels®To put it simply, it is not clear that a turkey-sized oven baking bag.
The appearance is more translucent beige, which is not suitable for solar cooking.
I just bought a pack of Heuck. ®Project 00124, one pack and two packs (www. heuck. com)
Bought from a local hardware store and installed on a wooden rack.
These oven bags are very clear and have also been designed to remain stationary at an oven temperature of up to 400 degrees F. 0006\" thick (versus .
Renault\'s 001\"®Oven baking bag)
It\'s almost as big as Renault. ®More dimensional stability than Renault®Bag.
But Heuck®The baking bag is a bit difficult to install because there are welds on both sides of the bag and folds on the bottom (
Open the slit in it). While the weld-
During the stretching process installed on the wooden frame, the weld will remain good
If not careful, the seams can be easily pulled away from the end and the zipper is opened.
After installation (
Stretch and bind)
, A clear 3/4 wide plastic strip is applied to all Staples (
Under the wooden frame)
Overlap with both sides to prevent Heuck®The baking bag torn off the staple food.
Also, while preparing for the hot pot trial run, I accidentally poked my finger at the seam, but fixed it quickly with. 25\" x 1.
5 \"a piece of transparent tape.
But I have not experienced a reflection temperature of more than 160 degrees F, so there are a lot of transparent plastic durable films that should be able to do a good job instead of using a fragile oven baking bag.
I am checking other plastic films that are transparent, thicker, wear resistant and can withstand up to 200-temperature
250 °F, anti-UV.
Keep an eye on the results.
I have a real problem with the idea of solar cooking using \"dispose\" items, so I urge you to also build this wooden frame to make the oven baking bag permanent and practical.
So I built a lightweight wooden frame with hinges and grooves to fit comfortably on the hot pot solar reflector.
A thin and horizontal wooden wrench is 65 ° (
Also the best solar cooking angle)
To block direct sunlight as little as possible.
Carefully polished to a smooth surface, the frame will prevent obstacles and tears, greatly extending the service life of the \"disposable\" oven baking bag.
However, the wooden frame will also provide much needed strength and stiffness for the fragile aluminum reflector, enabling it to withstand gusts and shaking winds.
Those delicate thin aluminum panels have aluminum hinges. . .
And aluminum hinge pin. . .
And aluminum rivets, if not reinforced, if it is not easy to damage and damage, can not resist shaking wind at all.
The wooden frame of the oven baking bag cover is hinged on the front, and the frame needs to be installed in odd-
The reflector of the shape, as well as the occasional opening of the top or front to stir and check the cooking process.
Together with 4 small hinges, 29 hinges.
The long hinge joint can also be conveniently stored and transported.
The wooden frame is fixed on the hot pot reflector by four long rubber bands, each attached to the front, rear, left and right view groups (
At the hinge joint)
, The other end of the rubber band hook on the eye shadow of each corner of the 5mm plywood base mounted to the reflector.
This provides additional strength and rigidity for the rig, and also makes it easier to open the top of the wooden rack to check and stir the contents of the hot pot.
I will upload more photos about this soon, as well as my cooking test results.
With this clock drive/Reynolds®Oven baking bag set in Turkish size, I was able to get good results for latitude.
For example, on a sunny day, there is no cloud, very breeze, May 5, in the northern hemisphere, 37 years old.
I poured a gallon of water 65 degrees Fahrenheit into the hot pot, and the ambient temperature was 75 degrees Fahrenheit.
I chose to test a gallon of tap water just to get the hot pot through a harsh test: _ solar _ HotPot environment _ HotPot hot pot _ reflector _ solar_time: _ temperature: _ 9: 00 a.

M. to 84 degrees F to 199 degrees F to 148 degrees F to 45 degrees F. The hot pot temperature in the morning is not too high, because the real star is actually 75 degrees
The ambient temperature is 85 F during the day.
But the 20 ° tilt needed to achieve the hotpot reflector at 9: 00 in the morning is a problem, as this is the first test of this exotic device.
However, the simple position modification of fixing the reflector on the plywood base should allow it to tilt now at 29 °. Finally!
Drive with clock/clear Heuck®Giant oven baking bag setting, I was able to achieve the best possible effect in latitude.
It was a sunny day. There was no cloud. The UV index was 7 (= high)
On May 9, the Northern Hemisphere, 37, was blowing the breeze.
At 5 ° latitude, I poured a gallon of water 63 degrees Fahrenheit in the hot pot, and the ambient temperature was 61 degrees Fahrenheit.
I chose to test a gallon of tap water just to get the hot pot to pass a harsh test: Sentence: Sun _ Time: Temperature: height: _ 9: 00 in the morning ___ 61 °F ___ 63 °F ___ 102 °F ___ 46 ° ___ to _ 4mph10: zero o\'clock A.

But the afternoon sun reflects my light.
The gray cement driveway, bathed with mirrors in the intense sun, causes the hot pot to heat to the hottest temperature of the day.
Therefore, please note that the optimal sun angle of the hot pot reflector is still maintained at 65 °.
In addition, the final hot pot temperature at 5: 00 186 F in the afternoon is important, because one of the drawbacks of the solar cooker is that the cooking time is not very consistent with lunch and dinner: most solar cooking equipment does not really start cooking until around noon, until noon
In the afternoon, the solar cooking window is usually closed.
However, with the hot pot table above, dinner will be served hot on the table.
The downside of all my research, adjustments and experiments is that my unique hot pot platform may not be predictable and reliable on days when the sun is below 70 degrees at noon.
In addition, the UV index of at least 7 is required because the UV radiation is actually cooked.
As far as my location is concerned, it means reliable solar cooking in the months of June, July and April, August or maybe a few days hot.
This means that my hot pot might be as useful in many days as my previous stylish ice cream freezer.
Of course, successful cooking may be done on the day of the Sun\'s height of 65 degrees at noon, but there is no room for cooking, if the weather is not as good as predicted.
But the test record above is a gallon (4 quarts)
Water so people can easily choose 3-quart, or a 2-
Quart recipes and have more control over the cooking process.
This information can be passed on to people living in other latitudes, as the sun\'s height at noon is indeed there.
Looking through the notes above, it is not a good idea to start cooking at 9: 00 in the morning, because the hot pot temperature before 11: 00 in the morning is only 142 degrees, if the food cannot reach the temperature of 140 degrees Fahrenheit, the food will deteriorate within two hours.
142 degrees Fahrenheit just pushed it too close.
It is much safer to start cooking at 10: 00 a. m. with a minimum Sun height of 57 degrees.
But starting at 9: 00 in the morning, it is useful to simply get a head
Start heating water or baking bread.
Temperature and standard 5-quart plug-
Electric Tank-
Pot™Slow cooker.
Like hot pot™It keeps cooking.
After departure, about an hour, the \"high\" setting of 250 W, the content is preheated to about 142 F, and then the rice cooker is switched to the \"low\" setting of 165 W, slowly heat to a maximum of 185 degrees Fahrenheit at the end of the day (
Cooking time of about 12 hours).
Again, the trick with hot pot is more than 70 °C (158°F)
But keep it below 100 °C (212°F)
Because steam is only a waste of energy, it is also a serious loss of water during cooking.
But unlike electric tanks
The pot is slow and the hot pot has no luxury of extending the cooking time.
But the fire boiler-roasting-
Bag combination, coupled with careful pan and tilt tracking, improves solar efficiency and is comparable to the performance of the tank
The Pot slow cooker on the 250-watt \"high\" setting (170-205°F).
We now have a solar stove that works reliably in temperate zones.
In addition, the global effective sun exposure map (pictured below)
This shows the best summer of the year, the solar cooking time of the hot pot restaurant every day (
Northern hemisphere, June): The 3. 0 -3.
If using a fire boiler, 9 solar cooking times per day in my area have basically doubledroasting-
Package combination, plus careful pan and tilt tracking.
So, now, guys, it looks like we\'re cooking with fusion.
The first thing I want to say is that the hot pot Sun stove is neither fried vegetables nor brown meat.
It\'s a bit disappointing as an empty hot pot can quickly and easily raise the temperature to 350-400°F.
I was hoping to simply add a meager 7 oz (200g)
Put chopped onions and 2 ounces of cooking oil into a hot empty hot pot so you can get a high
Fast stirring-temperature
Fry until it turns yellow a little.
But believe it or not, the process takes five hours.
Not worth it.
The second idea is that those simple additional cooking steps we take on the gas stove make our soup and stew taste better (
Initial stirring
Fried, roasted, caramel, etc. )
In fact, the energy consumption is very large, and the energy usually used is more than the energy used to extend the simmering process mainly.
Therefore, we decided to reduce our expectations of taste in some way through our hot pot cooking.
If possible, develop new recipes that work within the limits of solar cooking without affecting the taste.
We always like challenges.
I also tried baking a pound of yeast.
Bread made outsidethe-shelf HotPot-
But after baking for such a long time, the finished bread was dry, crispy and not very delicious.
But I\'ll try again with my new hack hot pot tracking device to see if faster cooking time will produce better bread.
Surprisingly, double
With its insulation, the Wall hot pot puts prepared meals on the table and runs through the whole meal.
But I decided to prepare and cook a hot pot full of chicken soup because it is predicted that the sun will have a noon temperature of 67 degrees Fahrenheit on July 30, 2011, the sky will be clear and clear, and the UV index at noon will be 10 (very high).
But I was flustered in the process of preparing the soup, in violation of my 3 quarts (2. 85 liter)
Cooking rules and make up a 1. 04 gallon (3. 95 liters)recipe. Weighing 8. 77 pounds (3. 99 kilograms)
, A mixture of chilled chicken, frozen vegetables, fresh vegetables and canned vegetables, with the contents of the hot pot at a temperature of 37 degrees Fahrenheit (2. 8°C)
I know I will be at a serious culinary disadvantage in the first place.
If the weather forecast is bad for solar cooking, cooking more than 3 quarts will leave me with no latitude and no errors.
Since the Sun height was 71 ° at noon that day, I installed a 70 ° timing wheel (4.
92 \"diameter, with 1. 22\" off-center axis).
Unfortunately, there is no weather forecast in the morning, cloudy to partly cloudy
Cloudy all morning.
Even with my Enhanced Hot pot equipment, potand-
Tilt the solar tracker and cover the frame with oven baking bag, I know I\'m really breaking the limits of the solar cooking setting.
But at noon, the sky cleared, there was no cloud, and the UV index was 10 (= very high)
With the breeze.

An hour later, the solar powered deceleration motor tracker turned off at 3: 00 P. M. , the solar reflector kept the lowest tracking angle, but continued facing the sun, and the reflector froze at 20 ° tilt.
But the afternoon sun reflects my light.
The gray cement driveway, bathed with mirrors in the intense sun, causes the hot pot to heat to the hottest temperature of the day.
Maybe the same can be achieved. of-
If the hot pot is set by the lake, the results of the day.
In addition, the final hot pot temperature at 6: 00 176 f in the afternoon is important, because one of the drawbacks of the solar cooker is that the cooking time is not very consistent with lunch and dinner: most solar cooking equipment does not really start cooking until around noon, until noon
In the afternoon, the solar cooking window is usually closed.
But with the hot pot on top, the dinner on the table is hot.
But, as mentioned earlier, I really worked hard because the potatoes were not completely finished at 5: 00 pm.
But everything was done by 6: 00 in the afternoon and I served the fully cooked meal to my grateful wife.
In addition, during the early cooking process, it took about 3 hours for the contents of the hot pot to rise from 65 degrees Fahrenheit to 140 degrees Fahrenheit.
It is not safe to practice as a habit, because if the temperature rises more than 2 hours, the food will deteriorate and rise from the ambient temperature to 140 degrees Fahrenheit.
In fact, the USDA went a step further, noting that the internal food temperature should not remain between 40 degrees Fahrenheit and 140 degrees Fahrenheit for more than two hours.
Conservative, 3-
Preparing the quart soup will keep the required cooking temperature at a normal level.
From now on, a reasonable cooking practice is to place a black steel inner bowl weighing 1 pound. 5 pounds (0. 68 kilogram)
, On the scale, add the contents of the recipe until the weight of the food in the bowl is no more than 7 lbs. 9 pounds (3. 59 kilograms)= about a 3-quart (2. 85 liters)meal.
In addition, those who live in the north latitude area, 2-
Quart meals may be a safer option.
I will post the chicken soup recipe above, but it is not as delicious as our usual chicken soup recipe with lots of cut and stir
Fried onion and grilled chicken greatly enhance the flavor of the soup.
But I will try some absolutely delicious jars of my wife\'s
Pot recipes, which we released as soon as we tried them out, show great prospects.
Hot water can be forced to use as mentioned earlier
Feed through hot pot and eat up to 2 to 3 times on a hot day.
I store the hot water at 0. 75 gallon (2. 84 liter)glass-
Vacuum cleaner lined.
Stainless steel-
The inner-lined vacuum airpot, while tougher and stronger, does not heat for more than a few hours. But a glass-
The inner vacuum cleaner will make me hard.
Earn hot water, hot: hot after 24 hours, hot after 48 hours, hot after 72 hours.
A can of 3/4 gallons of warm water may not sound like a commodity, but someone in a developing country can take a full bath, shave and rinse, also wash and rinse their clothes by hand from the day before. 3-
Warm water during the day can also be restored to boiling temperatures faster by pouring it into the hot pot and re-heating it.
A truly convenient feature of Airpots is that they have a handy push
Button or lever-
Pump, the top allows it to be used as a portable hot water faucet, placed in the entire summer cabin in the kitchen, dining room, bathroom, or generously lent to neighbors.
The forecast for August 2 is favorable: the noon temperature of the sun at 68 degrees Fahrenheit, the bright clear sky and the noon UV index of 10 (very high)
I decided to try this promising recipe.
I successfully cooked it in a charcoal Dutch oven a few years ago, but the recipe was lost.
But here\'s a close result: the Boston market style zucchini
8 ounces of pumpkin casserole (0. 5)water, 170°F (pre-
The day before, heat up the hot pot Sun stove and store it in a thermos bottle). 1/2 stick (2 ounces / 0. 13)
Margarine, room temperature. 12 ounce can (0. 75)
Light milk. 39 ounces (2. 47)
Yellow Pumpkin and zucchini pumpkin, cut into pieces of the size of a bite. 6 ounce (0. 38)chopped onion. 8 ounces (0. 50)
Grated cheddar cheese. 6 ounce (0. 38)
Packaging of dried seasoned corn flour stuffing. -----------------------------------------------------------------= 6.
A total of 61 pounds-1.
5 pound black steel liner pot = 5.
11 pounds melt the rod-shaped margarine Net into hot water, add the rest and stir well.
The initial temperature of the mixture is 90 degrees Fahrenheit before placing the hot pot reflector.
Weigh in well under 6. 32 pound (2. 79 kilograms)/3 quart (2. 85 liter)
Hot pot solar cooking rules, high
The actual size of the casserole is about 1 gallon (3. 80 liters)
In hot pot, but for solar cooking, weight is more important than volume.
This time, I know that I will start with a favorable culinary advantage.
If the weather forecast is not good for solar cooking, I still have enough latitude and a large range of errors.
Since the Sun height was 70 ° at noon that day, I installed the 70 ° timing wheel (4.
92 \"diameter, with 1. 22\" off-center axis).
Although the weather in the morning started from a cloudy sky, it was clear and sunny during the day at 10: 00 a. m. without clouds, and the UV index at noon was 10 (= very high)
With the breeze.
As casserole, the mixture will not be stirred after 10: 00 in the morning, the internal hot pot temperature is measured in two places and indicated below as the center-
Edge measurement.
Here are the results of the Northern Hemisphere in August 2.

At 3: 00 in the afternoon, the top of the casserole was Tan.
Sampling every hour, the casserole is actually fully cooked by 2: 00 pm.
And unlike chicken soup, this is absolutely delicious.
I keep cooking the casserole because I\'m excited about the new casserole --
At least in this recipe, the brown power of this solar oven is found.
Due to evaporation and my uncontrolled sampling, the volume of the finished casserole is much smaller than a gallon.
But for beginners, a simplethe-
Shelf hot pot can still be impressive at any Earth Day event: just open four to six cans of 15 oz high quality soup, chili, clam chowder or baked beans and then heat it quickly in hot pot.
