Abstract

Small deep-frozen balls or granules are produced by injecting a non-gaseous fluid into a refrigerant which is at vaporisation point, the size of the granules obtained being a function of the temp. difference between injected liq. and refrigerant and also of the injection press. The deep-frozen granules are removed directly from the bath to a vacuum chamber where almost all the refrigerant is evaporated from them and is returned to the freezing bath. An alternative system is to have a refrigerant bath that is airtight and operates under press. increasing the boiling temp. of the refrigerant. Excess refrigerant on the frozen balls is still removed in a vacuum chamber and re-injected into the pressurised bath. Liquids are injected into the refrigerant bath through sprays in the refrigerant, which is usually at atmos. press. and are removed from the refrigerating liq. by a conveyor which tips the frozen balls into a hopper connected by means of a rotating sealing valve to one or more vacuum chambers in parallel. The vacuum chambers are linked to a single vacuum pump, which evacuates the refrigerant vapours and returns them to the refrigerant bath. The chambers have at their outlets similar valves to the inlet so that a vacuum is maintained even during the emptying of the frozen granules. For refrigerant baths that operate under press. the vaporised refrigerant can be returned directly from the vacuum pump or can be re-liquified then injected into the bath. Process is used for deep freezing granules of liqs. in the food industry, e.g. coffee, crushed fruit juices, etc.
