Abstract

An automatic stir-fry machine to be placed on a commercial burner for cooking stir-fry dishes. The automatic stir-fry machine has a closed cooking chamber with only a rear exhaustion port, containing a cooking vessel formed primarily by two oppositely spaced apart vertical sidewalls and a generally cylindrical shaped bottom having a horizontal axis. A slice assembly is supported inside the cooking vessel and rotates about the horizontal axis of the cylindrical bottom of the cooking vessel, including a transverse scraping slice contacting the bottom of the cooking vessel with spring tension, and a pair of oppositely spaced apart and diagonally oriented stirring slices contacting opposite corners of the cooking vessel where the cylindrical bottom and the sidewalls join, for stirring, tossing and mixing food items inside the cooking vessel. A multiplicity of storage and delivery systems are provided for containing ingredients and condiments and dispensing pre-determined amounts of the ingredients and condiments into the cooking vessel at pre-determined times for cooking the stir-fry dishes. The automatic cooking operation of the automatic stir-fry machine can be controlled by a micro-processor unit.
