Embodiment Construction

[0022] Figures 1 and 2 show a cassette 1 comprising two heat exchanger plates 2 permanently connected together and a gasket 3 according to the invention. The two heat exchanger plates 2 have at least 4 inlets and outlets forming the inlets and outlets 4, 5, 6, 7 and a heat transfer surface 8 with several ridges 9 and recesses Valley 10. Cassette 1 can be made by welding or brazing, whereby the two heat exchanger plates 2 are permanently joined together along their periphery and around at least two of the inlets 4 , 5 .

[0023] The heat exchanger plates 2 are shaped in such a way that there are as few contact points as possible between two mutually adjoining cassettes, preventing the trapping of fibers and solid material that the fluid may contain in the spaces between the cassettes. According to the invention, the heat exchanger plates are also designed in such a way that the contact points for the necessary mechanical support are mostly produced only on the inner side betwe...

Abstract

A gasket assembly of a plate heat exchanger, comprising at least one gasket ( 3 ) and a package of heat exchanger plates ( 2 ) which are provided with inlet and outlet ports ( 4, 5, 6, 7 ) which constitute channels through the package and between the heat exchanger plates, whereby the heat exchanger plates are permanently joined in pairs to constitute cassettes ( 1 ), the gasket is disposed between the cassettes in a groove ( 12 ) in the heat exchanger plates and delimits in combination with the cassettes in every second space between plates a first flow passage for a first fluid, and the cassettes delimit a second flow passage for a second fluid. The gasket in the area around the ports comprises along its side facing the porthole a circumferential protruding bead ( 14 ). The invention also relates to a plate heat exchanger comprising the gasket unit, a heat exchanger plate and a gasket according to the invention.

Description

technical field [0001] The present invention relates to a gasket assembly for a plate heat exchanger, said gasket assembly comprising at least one gasket and a set of heat exchanger plates, said set of heat exchanger plates having inlets and outlets, the inlets and outlets Passages are formed through and between the above-mentioned packs of heat exchanger plates so that the heat exchanger plates are permanently joined in pairs to form boxes, with gaskets provided in grooves in the heat exchanger plates between the boxes , and in conjunction with each box defines a first flow channel for the first fluid in every other space between the plates, and the box defines a second flow channel for the second fluid. The invention also relates to a plate heat exchanger comprising a gasket assembly according to the invention, heat exchanger plates and gaskets. Background technique [0002] Food manufacturing often requires the processing and handling of highly viscous products such as c...
