Abstract

A system for use with a freezing liquid (refrigerant) spray refrigerator for foods, in order to purify the refrigerant contaminated with solid filth such as a scale of a fish, dust or the like. Removal of such solid filth from the refrigerant for purification and re-use of the purified refrigerant can be carried out by an arrangement, wherein the refrigerant once sprayed onto the foods for refrigeration and contaminated with solid filth such as a scale of a fish, dust or the like will be conveyed to a filter for separating the solid filth from the refrigerant contaminated with the solid filth; the refrigerant so treated will then be conveyed to a heater in order to heat the refrigerant thereby to flocculate a fat, blood or the like of the foods still remaining in the refrigerant; the refrigerant will further be conveyed to a filter to remove the coagulum; and the refrigerant so purified will finally be conveyed to a reservoir tank for re-use.
