This is a very general question.
Cryogenic freezing works depending on what materials you are trying to freeze, what problem you are trying to solve, and what kind of results you are expecting.
Cryogenics works well on metals. It works best on steels with high carbon contents. It also works quite well on aluminum.
If you are having wear problems, dimensional stability problems, fatigue problems, cracking failures then cryogenic treatment could be a good solution for your problem.
Often these problems are fixed completely. Sometimes, life can even be increased 100% to 300% for certain parts.
What are you trying to cryogenically freeze?
At the present time it is impossible to cryogenically freeze someone alive. No way exists at present to take the cells of the human body much below the freezing point of water and bring that person back. Ice crystals form and destroy human cells.
Any gas that liquifies below -150 degrees C is a cryogenic gas. The most popular cryogenic gas is liquid nitrogen.
flash freezing works when water is cooled below its freezing point to form supercooled water. when ice is added ice crystals instantly form around the ice to create a flash freeze
Freezing temperature make ice of the water in bacteria and completely stop there metabolic activity. Enzymes do not work at freezing temperature as they have no scope for movement in solid ice. So there activity halted.
Road Salt works because salt has a higher freezing point.
salting canning drying irradiating boiling curing and freezing are all methods of preserving foods
Cryogenic freezing is certainly related to nitrogen. In order to complete a deep cryogenic treatment a cryogen must be used. The least expensive cryogen for deep freezing is liquid nitrogen. Another cryogen is helium which allows special made cryogenic processors to reach temperatures approaching absolute zero.
Yes, on amphibians, reptiles and the like. No humans yet.
is a procedure that carefully destroys certain cells by freezing them
The selective exposure of tissues to extreme cold, often by applying a probe containing liquid nitrogen, to bring about the destruction or elimination of abnormal cells/ cancer.
it is used for foods such as strawberries or other kinds of berries which do not freeze well using conventional quick-freezing methods. can also be used for foods suck as shrimps which as high priced and have little moisture
cryogenic metal treatment
Any gas that liquifies below -150 degrees C is a cryogenic gas. The most popular cryogenic gas is liquid nitrogen.
Cryogenic freezing- is freezing the outer layers of the food beyond its freezing point while the inner part of that product remains warm, Its basically done to preserve foodorCryogenics is the branch of physics and engineering that involves the study of very low temperatures- how to produce it and how materials behave at those low temperatures.
No. Freezing destroys the cells.

A cryogenic freezer is used to bring components inside the freezer down to cryogenic temperatures. Many cryogenic freezers are available for all sorts of applications. Cold boxes with added ln2 capabilities can refrigerate parts and then complete cryogenic processing cycles. Additionally, cryo freezers are available to freeze sex cells, stems cells, and more. Sometimes people are frozen after death, which is called cryonics. I have added a site below that has cryogenic freezers and processors available.
