Abstract

A heat exchange device that can be used for continuously cooling or heating a slurry of food consisting of lumps in a non-viscous liquid. The device comprises several vertically spaced heat transfer trays in alignment with each other and each having an opening extending therethrough, that is not in alignment with like openings of adjacent trays, and having raised portions next to the openings to restrict the rapid flow of liquid through the openings, so the food slurry has to be pushed or scraped by slowly moving scraper members to each opening, where it can fall by force of gravity to an adjacent lower tray.
