<p>A trough construction including a trough (616) along which fluid is propelled to convey bagged product (108) therealong. A plurality of nozzles (604, 608) jet-spray cooling or heating water onto the bagged product (108) as it is conveyed along the trough (616). The nozzles (604, 608) are oriented in opposing first and second series so as to impart a rotation on the bagged product (108) generally about a longitudinal axis of the trough (616). According to one embodiment, a first suction tube (640) having openings through the trough (616) wall is opposite the first series of nozzles (604) and with a first pump (820) forms a first fluid circuit. Similarly, a second suction tube (644) with suction openings, together with a second pump (840) and the second series of nozzles (608) form a second fluid circuit. The two fluid circuits keep the bags (108) centered in the trough (616), surrounded by cooling or heating water. According to a second embodiment, the trough (120) is positioned in a sump (190) and has trough openings so that the fluid in the trough (120) communicates with that in the sump, and the suction tube (230) is the only suction tube used.</p> |
