Abstract: A flash freezing system is provided in which articles to be frozen are transported into, through and out of an elongated, thermally isolated chamber. Liquid nitrogen is sprayed onto the articles at one region of the chamber and flashes, at least partially, to gas which passes toward the end of the chamber into which the articles are introduced. Pumping means are provided together with a suction inlet and discharge outlet in the chamber to recirculate the gas at a high velocity and the freshly generated gas mixes with the recirculating gas in a high velocity stream impinging on each article. Means are provided to withdraw a portion of the recirculating gas from the end of the chamber into which the articles are introduced.

Abstract: A flash freezing system is provided in which articles to be frozen are transported through an elongated thermally isolated chamber. Liquid nitrogen is sprayed onto the articles where it flashes, at least partially, to gas which passes toward the article entrance end of the chamber. Pumping means is provided along with a suction inlet and discharge outlet in the chamber to recirculate the gas at a high velocity and the freshly generated gas mixes with the recirculated gas in a high velocity stream impinging on each article. Means are provided to withdraw a portion of the recirculated gas from the entrance end of the chamber.
