<p>A food processing system for heating and chilling of food products comprises a continuously running conveyor belt passing through food load and unloading stations and intermediate food heating and cooling chambers, there being spiral conveyor belt paths for carrying food products from the loading station to the heating chamber and from the chilling chamber to the unloading station, the system additionally comprising continuously operable belt cleaning and sanitizing means which are positioned in the belt return path from the unloading station to the loading stations. Also described is a food processing system including means for altering the temperature of food products passed through a food processing unit and also means for sanitizing the unit which pump a detergent cleaning solution through a rotating spray into the unit to reach all interior surfaces of the food processing unit. Also described is a method of sanitizing a food processing system with a conveyor belt having a grating aperture structure by pumping a warm cleaning liquid at a pressure of at least 100 psi (690k Pa) to a spray nozzle set positioned adjacent the conveyor belt so that detergent is released in a jet cleaning action against the moving belt. The specification also describes a process of preparing food products in which the products are quickly heated and cooled between input and output stations to ensure low bacteria count by heating the products solely by steam in an atmosphere of 100% humidity, and cooling the heated products to a temperature of less than 5 DEG C in an atmosphere of chilled moist air of 100% humidity.</p> |
