    Principle of operation and basic parameters of the solar parabolic cooker

    The reflector of a solar parabolic cooker (SPC) is axially symmetrical and shaped so its cross-section is a parabola; for that reason it has the property of bringing parallel rays of sunlight to a focus. What we have in parabolics is actually a focus spot with small but finite dimensions rather than an infinitly small focus point. If the axis...

    What requirements should satisfy the solar cooker cookware?

    Cooking and frying with the parabolic cooker are performed in ordinary commercial metal pots – usually from steel (Inox) and aluminium. Recommendable with thick thermo-bottoms. Also being used are thin-wall enameled steel pots without thermo-bottoms. Thin-wall cookware distributes the heat worse than thick-wall, so that could the food be burnt...

    Focusing of a solar parabolic cooker

    Focusing of a Solar parabolic cooker consists in targeting the reflector to the sun in such a way that the axis of the reflector is parallel to the direct sunlight. When this is fulfilled, the device is so designed, that the bright spot of the focus falls within the area of the supporting grid(supporting ring). In this sense, as synonyms are...
