ABSTRACT:
A conveyor system with cooling means is provided and comprises an elongated frame defining a conveyor track. An elongated conveyor is mounted within the frame so that a portion of the conveyor extends longitudinally along the conveyor track while a suitable motor longitudinally drives the conveyor along the conveyor track in a first direction. A plurality of cooling stations are also secured at longitudinally spaced positions along the frame so that the cooling stations are longitudinally adjacent each other. Each cooling station further includes a fluid reservoir beneath the conveyor track and a spray head positioned to spray fluid down onto the conveyor track. A pump is also provided for each cooling station and has its inlet connected to the fluid reservoir for that station while its outlet is connected to the spray head at the cooling station. The novelty of the present invention, however, resides in the provision of a thermocouple for sensing the fluid temperature in a fluid reservoir upstream from the outlet end of the conveyor system and, when the temperature in the upstream reservoir exceeds a predetermined value, fluidly connecting a source of relatively cool fluid to the fluid reservoir immediately adjacent the outlet of the conveyor system. In addition, a dam is provided between adjacent reservoirs so that the addition of relatively cool fluid to the reservoir immediately adjacent the outlet end of the conveyor system forces relatively cool water over the dam and into the reservoir second from the conveyor system outlet and so on throughout the length of the conveyor track. Evaporative cooling means are also preferably associated with one or more cooling stations in order to increase the overall cooling capability of the conveyor system.
