General Information |
: |
The important parts of a solar cooker include the outer box with thermal insulator, inner cooking box or tray, the double glass lid, mirror and cooking containers. The outer box is generally made of G.I. or aluminum sheet or fibre reinforced plastic.
The inner cooking box or tray is made from aluminum sheet and coated with black paint to absorb solar radiation and to transfer the heat to the cooking pots. The cooking tray is covered with a double glass lid in which the two glass sheets are spaced at about 20 mm to entrap air which acts a insulator and prevents escape of heat from the inside.
The space between the outer box and inner tray including bottom of the tray is packed with insulating material such as glass wool pads to reduce heat losses from the cooker. In addition to the above, the cooker is fitted with a mirror to increase the radiation input on the absorbing space. This radiation is in addition to the radiation entering the box directly and helps to quicken the cooking process by raising the inside temperature of the cooker.
The cooking containers (with cover) are generally made of aluminum and painted black on the outer surface so that they also absorb solar radiation directly.
