Spherical parabolic cookers are direct concentrating cookers with a dish-type reflector that directs most of the intercepted solar radiation to a focal point. This design enables quicker cooking and enhances the taste of the food. The cooking vessel is supported at this focal point, creating a heating situation similar to traditional open fire cooking. The concentrators can have shallow or deep dish shapes and can feature a continuous reflecting surface or be made out of concentric rings that support the focus of radiation. Dish-type concentrators rely on direct sunlight and need frequent orientation adjustments to face the sun.
