:

The cooker is of parabolic type having primary and secondary reflectors. The parabolic frame of the primary reflector is made of metallic square tubes. Secondary reflector sheet / mirror is so curved in shape that it reflects the incoming rays towards the bottom of the vessel. The stand on which the reflector frame is fixed is made of iron structure suitably painted. The movement of the rotating support on which the frame is fixed is done with the help of automatic tracking device. There is a pendulum clock work device with provision for seasonal adjustment.
