Question

explain how to make a solar cooker​

Answer 1

Explanation:

Solar cooking is done by means of the suns UV rays. A solar cooker lets the UV light rays in and then converts them to longer infrared light rays that cannot escape. Infrared radiation has the right energy to make the water, fat and protein molecules in food vibrate vigorously and heat up.

Answer 2

Steps To Make a Solar Cooker =>

Step-1 =>

Fold the top pads closed on the larger box and place the inner box on top and drop a line everywhere it onto the top of the larger box. Remove the smaller box & cut end to end to make a hole in the top of the larger box. Maintain I inch space between these two boxes.

Step-2 =>

Using a scissor or knife, cut the corners of the inner box(small box down to that height. Fold every side of the box down to form extended flaps. Folding is simple, if you first draw a fixed line from the one cut end to another.

Step-3 =>

Some twists of creased newspaper into the external box so that when you fix the smaller box down inside the hole in the external box, the pads on the inner box touches the top of the external box. Paste these pads onto the top of the external box and cut the extra pad’s length to be even with the edge of the outer box.

Lastly, to make the drip pan, cut a part of cardboard similar to the bottom of the inner of the oven and apply foil to one side. Paint black spray paint at foiled side and let it dry. Place this in the oven so that it rests on the end of the small box, and place your containers on it when cooking. Now the base of the cooker is completed.

Step-4 =>

Reflector pad of the cardboard box can be designed by drawing a line on the lid. Making a rectangular cut three sides around the box and fold the resulting pad up to make a reflector. To design a 30cm prop bend part of hanger wire as specified in the diagram, then it can be injected into the corrugations as shown.

Finally, turn the lid from upside to down & attach the bag in the place, that makes a double plastic layer These two layers tend to detach from each other to form an airspace as the oven cooks.
