Patent number: 6665951Abstract: Spin drying of a stack of flats such as egg trays is performed within a housing by movement of a rotatable lifting head into engagement with the undersurface of the stack. A stack lifting device lifts the lifting head and the stack of flats positioned thereon vertically upwardly into engagement with a drive engagement device thereabove which is rotatably powered by a drive with an optional braking device. Operation of the drive will cause rotation of the lifting head, the stack of flats and the drive engagement device simultaneously. The stack of flats will be held between the lifting head engaging the lower surface thereof and the drive engagement device engaging the upper surface thereof for fixedly securing these three elements together during powered rotation thereof. The rotation will spin off any liquids remaining on the flats such as would be present after being washed.Type: GrantFiled: August 22, 2002Date of Patent: December 23, 2003Inventor: Jeffrey B. Kuhl

Patent number: 6655041Abstract: The invention relates to a roller belt drier. The drying of panel-shaped products often requires the drier to have considerable construction lengths in order to achieve a high capacity. Long roller belt dryers, which are usually equipped with chain drives and a motor for each chain, present the problem that very strong chains are required to transmit the necessary driving forces. When the drier reaches a certain length, it is no longer possible to provide chains that are able to accommodate these forces. According to known solutions, a chain is divided and the drives are located in the centre of the drier. This causes problem s in terms of sealing the drier, as well as extra expense for the driving and tension station. The aim of the invention is to create a drier which has a driving and tension system that is structurally simple and economical even for considerable construction lengths. A chain is equipped with two drives (15, 23), the second drive (23) being integrated in a tension device (24).Type: GrantFiled: April 30, 2002Date of Patent: December 2, 2003Assignee: Babcock-BSH GmbHInventors: Manfred Schmidt, Gerhard Lehn, Bernd Schneider

Patent number: 6655043Abstract: A moisture indicator in an air flow drying process where hot gas is circulated over and around a granular material having an undesirable amount of moisture includes a detector located in the path of the exhaust gas to determine exhaust flow temperature, a valve control device associated with the temperature detector to control the percentage of hydrocarbon gas in the hot gas intake and an indicator connected to the valve control device. A display is associated with the indicator to display the percentage of hydrocarbon gas in the gas intake which indicates the amount of moisture in the granular material. The percentage of hydrocarbon gas needed in the intake is inversely proportional to the amount of moisture in the granular material. The percentage signals the loader operator whether the granular material loaded has an acceptable amount of moisture for successful operation of the drying process.Type: GrantFiled: September 21, 2001Date of Patent: December 2, 2003Assignee: APAC Inc.Inventor: Ernest Roy Kingery
