Immersion bath freezers consist of a liquid nitrogen (LIN) bath, in which you can rapidly freeze products to very low temperatures by direct immersion in the cryogenic liquid at atmospheric pressure. Depending on the residence time in the cryogenic liquid, the products can be only crust frozen (by a short immersion) or completely frozen (down to -195,8°C). Many of these applications are in the food industry, where bulk, free rolling and small products are immersed directly into the bath of liquid nitrogen. Other applications use liquid nitrogen to make metals or plastics extremely brittle for subsequent cryofracture, deburring or grinding.
