WebCryogenic freezing. Cryogenic freezing is the fastest IQF freezing method on the market. In cryofreezing, the items are sprayed or immersed directly in liquid nitrogen or carbon dioxide and frozen almost instantly. The method prevents the formation of macro crystals – which is preferable, as large ice crystals rupture the food’s cell ... WebApr 3, 2024 · CO 2 turns from a gas to a solid between -75 and -90 C (-103 and -130 F). So it is already naturally falling like snow in Antarctica when the temperature is right. But as the temperature rises, the solid CO 2 goes back into the air. Flannery argued that adding artificial refrigeration to the process can freeze both water and CO2 together into ...
