Two types of solar cookers

Type: Parabolic

A. The details of material used:

1. Stove surface: thin-typed cast-iron – 3mm

It is accurate in molding- not easy to damaged- easy to disassemble and transport.

2. The reflector: vacuum aluminum-plated

The reflecting capacity is strong, the heating efficiency is high and it’s convenient for repairing and changing.

3. Bracket: cast-iron

The framework of the principal axis of the cooker body is supported by the bar centre. It’s stable and reliable. It’s convenient to adjust at required angles.

In this kind of solar cooker you can boil water, stir-fry, deep-fry and so on. The solar energy is its fuel. It can be used to supply hot water or boiled water for tea. It also can be used to do the steamy disinfections with suitable steel wares.

B. The Countries where these type of solar cookers are in use

1. In Middle and Southern American countries

2. In many African countries especially in Kenya

3. Some countries of Oceania

4. India, Nepal & China

C. Working principle

We select and design the revolving parabolic sunlight-withholding surface by combining the “draw-making method of 3-circle” and the thin-typed founding techniques, which guarantees the sunlight from different height and angles can reflect and collect at the bottom of stove effectively. All rays from parabolic curve reflect and concentrate at the ring where pot is placed. As the solar energy is clean and environmental-protected, the cooked food is not only delicious taste and beautiful seeing, but also is good for health. Invest once and you can get the long-term benefit.

D. Other Instructions

1-      As the temperature of the bright spot is very high, pay special attention not to let the bright spot move to human body or other objects to avoid body damage or setting fire on other objects.

2-      The solar cooker should be set in a place exposed to the sun and sheltered from the wind, so that the strong wind couldn’t damage the oven.

3-      When the reflective membrane is covered by dust, don’t wipe it with dry cloth. You may clean it with a bit detergent and, then wash it with clean water.  Small amount of dust doesn’t influence the normal function.

4-      When the solar cooker is not in use, turn the cooker’s back towards the sunlight to extend the life time of the reflective membrane.

5-      Use the utensils or pots with black bottom.(it could be blackened by black ink or smoke) to enhance the effect of absorbing heat.

6-      When heating water, be careful not to fill water to the top in order to avoid overflowing.

7-      The empty pot should not be placed on the solar cooker; otherwise the empty pot’s bottom will burnt out.

8-      The flammable objects, such as firewood or fuel, are forbidden to be placed around the solar oven to prevent fires accidents.

9-      During usage, children are forbidden to approach or shake the oven to avoid being burnt or injured.

10-   During usage, you should not look at the bright spot for a relative long time to protect the eyes from being injured.
