HEAT EXCHANGER EJECTOR APPLICATION IN PRODUCTS REFRIGERATION PROCESSING

This paper describes the use of a heat-exchanger ejector device for air humidification in a refrigeration treatment camera of meat half-carcasses, and the possibility of its application for artificial snow. The system of a two-step meat moistening in the isolated compartment by treating meat with a mixture of cooled air and the fine crystal ice particles is represented in this article. The design scheme and the principle of the heat exchanger ejector is shown. The ice crystals formed at the outlet of the diffuser of the heat exchanger-ejector from the mixture of injected water droplets through the nozzle into the incoming stream of compressed cooled air. Application of a heat exchanger-ejector allows to get 100% relative humidity in the chamber. Heat exchanger ejector can be used for meat stacks snowing.
