Publication number: 20220048713Abstract: A cleanable frame and a method for making a cleanable frame having a simplified frame design. A hygienic conveyor frame assembly comprises a plurality of hollow tubular sections joined together to form an evacuated, sealed conveyor frame support structure that functions as a sterilization zone. An integral carryway is placed on the support structure. Lifters coupled to the conveyor frame can lift the carryway and conveyor belt for cleaning. Infeed and outfeed assemblies are also movable between operating and cleaning positions. A sensor can monitor the conditions of the frame interior to ensure that the vacuum is maintained and initiate a corrective action if the vacuum seal is breached.Type: ApplicationFiled: October 28, 2021Publication date: February 17, 2022Inventors: Michael Hendrik DeGroot, Jeff Batchelder, Gerko Hulshof, David A. Kokx, James R. Honeycutt, JR.
