Flash frozen in liquid nitrogen
In physics and chemistry, flash freezing is the process whereby objects are frozen in just a few hours by subjecting them to cryogenic temperatures, or through direct contact with liquid nitrogen at −196 °C (−320.8 °F). It is commonly used in the food industry. Flash freezing is of great importance in atmospheric … See more When water is supercooled to temperatures below −48 °C (−54 °F), it must freeze. When water is in a conventional freezer, a dynamic phase transition is triggered. The resulting ice … See more There are phenomena like supercooling, in which the water is cooled below its freezing point, but the water remains liquid, if there are too few defects to seed crystallization. One … See more Flash freezing is used in the food industry to quickly freeze perishable food items (see frozen food). In this case, food items are subjected to … See more For the understanding of flash freezing, various related quantities might be useful.
