Abstract: A hide-on washer module includes striker assemblies mounted for vertical displacement from hydraulic cylinders. When each hydraulic piston reciprocates vertically, the striker assemblies and T-shaped tracking plates are displaced concomitantly. Roller assemblies are mounted to floor-mounted vertical columns that are interconnected to one another by stabilizer plates. A first set of roller assemblies engages a first tracking plate, a second set of roller assemblies engages a second reciprocating tracking plate, a third set of roller assemblies are mounted to the rear side of a front column, a fourth set of roller assemblies are mounted to the front side of a rear column, a fifth set of roller assemblies is mounted to the rear side of a front column, and a sixth set of roller assemblies is mounted to the front side of a rear column. Each roller assembly is biased to bear against its associated tracking plate.

Abstract: A modular conveyor belt passes over and around at least one sprocket carried on a non-rotating hollow shaft and causes rotation of the sprocket. The sprocket includes a first pair of diametrically opposed sectors and a second pair of diametrically opposed sectors that are laterally staggered in relation to the first pair of sectors. Each sprocket is flanked by a pair of nozzles, each of which produces a fan-shaped spray. The fan-shaped sprays overlap one another across the lateral extent of the belt so that the entire breadth of the belt is cleaned. Adjacent fan-shaped sprays are angled relative to one another so that their respective sprays do not interfere with one another. The staggered sector design ensures that all sections of the belt are exposed to the spray. The nozzles are positioned to clean hinges of the belt when the hinges are open.
