Abstract
A high efficient gas fired frying apparatus for deep frying food is disclosed. The gas fired frying apparatus is comprised of a supply system for air and fuel gas, a compression system, a burner system, a combustion chamber, a heat exchanger and an exhaust system. The air and fuel gas are mixed and pressurized prior to being introduced to the burner system. The burner system works in conjunction with the combustion chamber to support combustion by balancing the premixture velocity with the flame velocity such that smooth and complete combustion occurs. The high velocity components of combustion are directed through a heat exchanger which transfers the heat to the cooking oil. The exhaust system recovers additional energy from the products of combustion and a catalytic converter may be added for removal of unwanted pollutants. Both the combustion chamber and the heat exchanger are removably disposed within the frypot to facilitate cleaning and oil replacement.
