Question

With the neat diagram, explain box type solar cooker.

Accepted Answer

Box type solar cooker is used to cook food using the heat energy from sun. A thick glass sheet covers the box and a plane mirror reflector is attached to the box. The food to be cooked is put in metal containers which are painted black in colour from outside. These metal containers are then placed inside the solar cooker box and covered with a glass sheet. The solar cooker is kept under sunlight. The radiation from the sun passes through the glass sheet. These are then absorbed by the black container. Once the sun’s heat rays enter the cooker box, then the glass sheet cover does not allow them to go back.

The reflector of solar cooker is adjusted in such a way that maximum sunlight falls on it. In this way, more and more heat rays of the sun get trapped in the box due to which the temperature in the solar cooker rises to about $100 ° C$ to $140 ° C$ in two to three hours. But this type of solar cooker can be used to cook only those food materials which require slow heating. It cannot be used for food which requires more heat to cook.
