ABSTRACT:
A flowable food product or other substance is heated or chilled by pumping it through a long, slender tube on a continuous basis in one direction only while simultaneously subjecting it to a temperature differential. The body of product contained within and moving through the tube is segmented into a number of discrete, end-to-end but longitudinally spaced-apart sections by plugs that are periodically introduced into the tube and moved along with the product. The plugs continuously scrape the wall of the tube free of any accumulation of frost or cooked-on material without interrupting the continuous flow and without subjecting the product to deleterious shear stresses. The frequency of plug insertion can be varied without changing the rate of product flow along the wall of the tube so that the best combination of temperature, speed, and scraping frequency can be achieved for each product formulation on a custom basis. The temperature differential may be created by guiding a heat exchange medium around the tube in a helical pattern and in counterflow relationship to the advancing product. As an alternative, microwave energy may be used alone or in conjunction with a fluid medium.
