While CO2 and liquid nitrogen have some differences as freezing agents, both work well on baked goods and geographic availability should be the main decider, Praxair says.
Affordability, ease of use and space savings are all benefits claimed by Air Products for its cryogenic tunnel freezer to be launched in Europe later this month.
A new delivery system for liquid nitrogen - widely used in the food
processing industry - should dramatically reduce the time between
dosing and closure, ensuring more accurate and effective
pressurisation, writes Chris Jones.
