METHOD FOR EXCHANGING HEAT BETWEEN A HEAT EXCHANGE FLUID AND A PERISHABLE PRODUCT FLUID, A REMOVABLE HEAT EXCHANGE CARTRIDGE AND A HEAT EXCHANGE SYSTEM

摘要

A method for exchanging heat between a heat exchange fluid and a perishable product fluid. The method comprises providing the heat exchange fluid to an enclosure 5 of a heat exchanger and providing the perishable product fluid to a tube 53 comprising a flexible portion in the enclosure 51. The method comprises exchanging heat between the heat exchange fluid in the enclosure and the perishable product fluid in the tube53 and interrupting providing the perishable product fluid to the tube 53. The method further comprises compressing the flexible portion of the tube 53 to decrease a volume of the tube 3 and to press a substantial part of the perishable product fluid out of the tube 53. The method may comprise changing the heat exchange fluid at a first temperature to a heat exchange fluid at a second temperature different than the first temperature.
