Abstract
Abstract THERMOPLASTIC PROTECTIVE OR MOISTURE RESISTANT COAT INGS, E.G. HYDROGENATED VEGETABLE OIL, ARE APPLIED TO A FOOD PRODUCT BY METERING THE FOOD PRODUCT AND THE THERMOPLASTIC COATING INTO A COATING ZONE, MAINTAINING THE THERMOPLASTIC COATING MATERIAL IN A LIQUID CONSISTENCY IN THE COATING ZONE WHILE MINIMIZING THE HEATING OF THE FOOD PRODUCT TO THEREBY ESTABLISH A TEMPERATURE DIFFERENTIAL BETWEEN THE COATING AND THE FOOD PRODUCT AND AGITATING THE FOOD PRODUCT TO SPREAD THE HEATED LIQUID COATING OVER THE SURFACE OF THE FOOD PRODUCT AS A CONTINUOUS FILM AND ALLOWING THE LIQUID TO CONGEAL ON THE SURFACE OF THE FOOD PRODUCT. TYPICALLY, HEAT IS APPLIED TO THE OUTSIDE SURFACE OF A ROTATING COATING CYLINDER TO HEAT OR MAINTAIN THE COATING MATERIAL IN A LIQUISD CONDITION BY CONDUCTION.
