Pressurized liquid cooker with integrated radiant heating apparatus

摘要

A pressurized batch cooking pot has an encircling radiant heater which has a high temperature insulation shell with end abutting the pot and a center portion spaced from the pot. A spiral coil is firmly embedded within the inner wall of the insulation shell with the outer surface of the coil turns opposed to the pot exposed and flattened. The oil level in the pot is somewhat above the uppermost end of the heating coil. The air gap between the coil and the pot is selected for efficient energy transfer. The spiral coil is formed in vertically spaced rows circum-ferentially distributed about the pot. Integral end connections are formed substantially rectangular with a plurality of coil turns integrally joined to the turns of the parallel rows by a similar integral U-shaped wire. The pot is a relatively elongated unit having a length to diameter ratio of at least 1.6 to 1. The outside of the sidewall of the pot has a black body coating. The cooking oil is operated with a cooking temperature of approximately 300 DEG F. to 335 DEG F. The heater is a modular construction having identical sections for each phase line of the supply.
