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.
Claims12
Freezing and cooling apparatus using a liquefied gas having a liquid state and gaseous state comprising in combination:
- a housing for receiving edible products to be frozen;
- means for moving edible products into and out of the housing;
- means for providing a spray of the liquefied gas on the edible products in the housing to freeze the edible products;
- chiller cabinet means for receiving the gaseous state of the liquefied gas;
- means for conveying the gaseous state of the liquefied gas out of the housing and to the chiller cabinet means;
- means for providing a flow of water in the chiller cabinet means whereby the water is cooled by the gas;
- and
- means for pumping the cooled water out of the chiller cabinet means.
A method of using a gas in its liquefied and gaseous states comprising in combination the steps of:
- providing a housing;
- providing a liquefied gas in the housing;
- providing an edible product in the housing;
- spraying the liquefied gas on the edible product to freeze the edible product;
- collecting the gaseous product from the liquefied gas spray;
- providing a chiller cabinet;
- providing a flow of water to the chiller cabinet;
- and
- transmitting the gaseous product to the chiller cabinet for cooling the flow of water in the chiller cabinet.
