Abstract

A water tank is divided into a first heated compartment and a second heated compartment by an insulated baffle. A perforated cylinder is mounted within the tank and has a first segment which extends within the first heated tank compartment and a second segment which extends within the second heated tank compartment. Portions of a helical auger extend within each cylinder segment. Heated water at a first temperature is supplied to the first heated compartment by a first heated water manifold, and heated water at a second, higher temperature is supplied to the second heated compartment by a second heated water manifold. Mixing of the two temperatures of water is prevented by the insulating baffle. Food product is caused to traverse the length of the first heated compartment by the auger, and is transferred over the baffle into the second heated compartment by a lifting flight which elevates food product from the water into a chute which discharges into the second heated compartment. A tank may be divided into three or more compartments for more particular control of product heating. A single self-contained apparatus thus blanches and food product through a range of temperature regions in a continuous process.
