Tolokatsin Solar Cooker
Wall oven variation where food can be accessed from inside the house
In 1995 the first Tolokatsin Solar Cooker was designed and constructed, based on non-imaging optics, with a multi compound solar concentrator, a hollow cylindrical absorber inside which a stainless steel recipient for containing the food to be cooked. They could be sized for practically any volumetric capacity (from 1 to more than 100 L) with only slight variations in their design parameters. These solar ovens were designed to heat up quickly, but after reaching around 100 °C (212 °F) the temperature doesn’t go much above 120 °C (248 °F) in order to avoid the formation of hazardous substances, like acrylamides, or the burning of the food. However, for semi-cloudy skies, this limited concentration delayed the cooking time, and jeopardizing the success of the process in cloudy days. The new solar cooker Tolokatsin V has a much greater geometric concentration, and optimized according to Rincon criteria, and it also has a higher optical efficiency. Even though its stagnation temperature is 160 °C (320 °F), this value cannot be reached out with full meal charge, when it works in a stationary position. This allows a safe and quick cooking even in semi cloudy days, more efficiently than with the Tolokatsin original design.
