Patent number: 6572261Abstract: An agitator assembly for mounting in a wall of a storage tank that includes a body having a rotatable shaft extending therethrough. The body includes a duct having a diameter that is larger than the diameter of the shaft to allow passage of a fluid therebetween. An impeller is secured to one end of the shaft and a collar is secured to the other end. A bushing is provided between the body and the shaft and allows passage of a fluid during a cleaning cycle. A motor assembly is attached to the shaft and provides power for rotation of the shaft. A resilient member is provided over the shaft between the motor assembly and collar to control axial movement of the shaft. During a cleaning cycle, fluid pressure overcomes the biasing force of the compressible member permitting the fluid to escape the body to effectively clean the impeller.Type: GrantFiled: June 12, 2001Date of Patent: June 3, 2003Assignee: Walker Stainless Equipment CompanyInventors: Richard L. Angerhofer, Robert J. Anderson, Randall S. Anderson

Patent number: 5953983Abstract: An enclosed food processing device is provided having one or more conveyor belts and vertically rotating agitators positioned above the belt. The agitators have forwardly and rearwardly projecting prongs that stir the food being processed without causing physical damage to it. The preferred forwardly projecting prongs are elongated and have a generally rounded cross-section. The preferred rearwardly projecting prongs may be staggered or otherwise arranged so as to break up clumps while permitting curds to pass between them.Type: GrantFiled: March 12, 1997Date of Patent: September 21, 1999Assignee: Walker Stainless Equipment Company Inc.Inventors: John M. McCormick, Virgil J. Scherping, George H. Schwinghammer, Gary L. Starkson

Patent number: 5921677Abstract: An enclosed food processing device is provided having one or more conveyor belts and vertical agitators positioned above the belt. The agitators have forward and backward prongs that stir the food being processed without causing physical damage to it. The food enters the device through an inlet and is evenly distributed across a draining screen by an inlet deflector plate, which is adjustable to account for the different rates at which the food may flow into the device. Ramps are positioned under the device to collect liquid drained from the food, and the ramps have independent segments that separate the liquid based on the stage of the process at which it is drained from the food. A salting apparatus is provided for conveying salt to the food to be processed. The salt is dispensed in proportion to the amount of food to be salted. Salt is moved from a salt hopper into a chamber by a rotating dispensing wheel.Type: GrantFiled: March 20, 1997Date of Patent: July 13, 1999Assignee: Walker Stainless Equipment Company, Inc.Inventors: Virgil J. Scherping, George H. Schwinghammer, Gary L. Starkson
