Abstract

A unique spiral vapor cooker and cooking process comprises an insulated housing defining cooking chamber including a reservoir of heated water therein. Rising within the cooking chamber is a vertically oriented spiral conveyor carrying a stainless steel mesh conveyor belt. Water vapor rises through the mesh conveyor belt from a downwardly flowing source of heated water passing underneath the conveyor belt by a generally U-shaped water channel positioned underneath the conveyor belt. The bottom of the channel is randomly perforated permitting passage of water out of the channel to baste food product carried on a below positioned conveyor belt. The channel follows the entire path of the belt. Water at a preferred temperature of 200-205 degrees Fahrenheit is pumped upwardly from the water reservoir to a top portion of the water channel and flows downwardly within the channel while the conveyor carries the food product upwardly over the surface of the channel.
