Publication number: 20100031689Abstract: The invention relates to a device for the rapid freezing of the surface or for the complete freezing of starting substances, in particular of food or pharmaceuticals, said device comprising a treatment zone (B), through which a cryogenic liquefied gas flows as a coolant, said gas thereby freezing at least the surfaces of the starting substances and thereby causing relative movements between the starting substances, which are immersed in the coolant. The treatment zone (B) is made up of modules (M1, M2, M3, M4) and the length thereof can be changed by adding or removing one or a plurality of modules.Type: ApplicationFiled: September 14, 2007Publication date: February 11, 2010Inventors: Rudolf Erwin Berghoff, Joe Wijlens

Publication number: 20090308263Abstract: The invention relates to a device for the refrigerating and/or the freezing of starting substances, in particular of food, comprising two treatment zones, which are enclosed by a housing and which abut directly on one another, wherein heat can be extracted from the starting substances in at least one of the treatment zones in direct or indirect contact with cryogenic liquefied gas, while the second treatment zone encompasses a conveyor belt for conveying the starting substances through the second treatment zone. The device comprises a gas suction device, by means of which a drop of pressure can be generated within the housing and due to which the cold gas, which is generated in the first treatment zone by means of evaporation of cryogenic liquefied gas, discharges from the first treatment zone and subsequently flows through the second treatment zone and also contributes there to the cooling of the product.Type: ApplicationFiled: September 14, 2007Publication date: December 17, 2009Inventor: Rudolf Erwin Berghoff

Patent number: 7322206Abstract: A device for refrigerating and/or freezing products in which the products are conveyed by a conveyor belt through a treatment zone equipped with refrigeration equipment. The conveyor belt passes over sliding rails which are mounted on a supporting frame. To prevent excessive sticking of products on the conveyor belt, the sliding rails are arranged with a convex and/or concave curvature in at least in some sections, so that the conveyor belt slides on predetermined curvatures. Shearing forces are therefore created at the contact faces of the conveyor belt and product, resulting in release of the product.Type: GrantFiled: April 21, 2005Date of Patent: January 29, 2008Assignee: Linde AktiengesellschaftInventor: Rudolf Erwin Berghoff

Patent number: 7156364Abstract: A valve assembly for controlling flow of cryogenic fluids is disclosed. In an embodiment, the valve assembly includes a valve housing and a valve member supported at the valve housing for movement between a valve opened and a valve closing position. A pneumatic cylinder is disposed laterally spaced from the valve member and thermally isolated with respect to cryogenic fluids controlled by the valve member. A lever operatively connects the pneumatic cylinder with the valve member and a linkage is pivotally connected with the lever at a position spaced from the valve member. The valve member is a needle valve member supported for axial movement at the housing.Type: GrantFiled: October 12, 2004Date of Patent: January 2, 2007Assignee: Linde AktiengesellschaftInventor: Rudolf Erwin Berghoff
