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.

A heat exchange device for continuously cooling or, in the alternative, heating a slurry of food consisting of solid lumps in a non-viscous liquid, comprising: (a) a plurality of heat transfer trays, aligned with each other and interconnected in vertically spaced relationship; (b) food inlet means connected to an uppermost tray and food outlet means connected to a lowermost tray; (c) each of said trays including a round, horizontal plate and a vertical wall upstanding from the periphery of said plate; (d) each of said plates having at least one internal passageway to accomodate the flow of fluid therethrough for cooling or, in the alternative, heating said plate; (e) each of said plates having a radially disposed opening extending vertically therethrough and free from alignment with an opening of any adjacent plate; (f) means for slowly moving a food slurry over each plate until it reaches said plate opening where it can fall by gravity therethrough onto an adjacent lower plate, said means comprising: (i) a rotatable drive shaft extending vertically through said plates; (ii) a plurality of scraper members secured to said shaft, each of said members being adapted to engage food slurry on a related plate and move it toward an opening of said plate; (g) each of said plates including a pair of radially disposed raised portions located on opposite sides of the plate opening to partially restrict the free flow of liquid from said plate through said opening.
