[0008]The object of the invention is to eliminate or at least reduce the problems indicated above and to provide an improved solution for a porthole of a heat exc...

Problems solved by technology

When two or more heat exchanger plates are placed adjacent to one another, however, the nibs result in the formation of spaces in the actual flow passage, i.e. dead zones in which flowing liquid may become stationary and solid mate...

Embodiment Construction

[0022]FIGS. 1 and 2 depict a cassette 1 comprising two heat exchanger plates 2 permanently joined together and a gasket 3 according to the invention. The plates have at least four ports constituting inlet and outlet ports 4, 5, 6, 7 and a heat transfer surface 8 with ridges 9 and valleys 10. The cassette 1 may be made by welding or brazing, whereby the two plates 2 are joined together permanently along their periphery and around at least two of ports 4, 5.

[0023]Configuring the heat exchanger plates 2 in such a way that as few contact points as possible occur between two mutually adjacent cassettes prevents fibres and solid materials which may be contained in the fluid being caught in the space between the cassettes. According to the invention, the plates are also so designed that contact points for necessary mechanical support occur largely only on the inside, between two plates which are to be joined together to form a cassette, by opposite ridges abutting against one another. In c...

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

FIELD OF THE INVENTION[0001]The present invention relates to a gasket assembly of a plate heat exchanger, comprising at least one gasket and a package of heat exchanger plates which are provided with inlet and outlet ports 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, the gasket is disposed between the cassettes in a groove 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 invention also relates to a plate heat exchanger comprising the gasket assembly, a heat exchanger plate and a gasket according to the invention.BACKGROUND TO THE INVENTION[0002]Food manufacture is typically characterised by the need to process and treat highly viscous products, e.g. concentrates for carbonated be...
