ABSTRACT:
Nitrogen fruit freezing apparatus includes a conveyor on which fruit passes beneath a spray of liquid nitrogen, and the liquid nitrogen falls downwardly, gasifies, and flows to a chiller unit where the gas is used to cool water. The water cooled by the nitrogen gas is sprayed onto the fruit before the fruit is conveyed to the liquid nitrogen freezing area and is sprayed onto the fruit to glaze the fruit after the fruit is frozen. The cooled water may also be used for cooling a room or a building, etc. The nitrogen gas is exhausted to the atmosphere from the water chiller unit.
