Cryogenic IQF freezers immerse the product in liquid nitrogen at very low temperatures, freezing it rapidly while continuously moving the product to avoid block or lump formation. [5] Although this method shows good freezing results, it might lead to higher processing costs per weight of product due to the cost of the liquid nitrogen required.
Cryogenic freezing is the quickest freezing technology available due to the ultra low liquid nitrogen temperature −196 °C (−320 °F). [ 2 ] Preserving food in domestic kitchens during modern times is achieved using household freezers .
The food undergoes a process of cryogenic freezing with liquid nitrogen. After the food is placed on the conveyor belt, it is sprayed with liquid nitrogen that boils on contact with the freezing food. This method of flash-freezing fresh foods is used to retain natural quality of the food.
Freezer milling is a type of cryogenic milling that uses a solenoid to mill samples. The solenoid moves the grinding media back and forth inside the vial, grinding the sample down to analytical fineness. This type of milling is especially useful in milling temperature sensitive samples, as samples are milled at liquid nitrogen temperatures. The ...
Dippin' Dots are stored and transported at –40 degree Fahrenheit (–40 °C), which is colder than most frozen foods require. The company's development of ultra low temperature freezers, proper storage and transportation got the company involved from about 1988 with selling their equipment for other uses, such as preserving microbiological cultures for fermentation.
Earlier this month, the organization that has provided food to more than 2.4 million people across five counties achieved a new level of cool — a 1,056 square-feet freezer, which allows it to ...

The hand-cranked churn produced smoother ice cream than the pot freezer and did it quicker.
