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 food
or
Cryogenics 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.

∙ 16y agoCryogenics is the study of the production of very low temperatures (below –150 °C, –238 °F or 123 K) and the behavior of materials at those temperatures. (Rather than the familiar temperature scales of Fahrenheit and Celsius, cryogenicists use the Rankine and Kelvin scales.)

What is the extraction of separate oxgyen and nitrogen?
The separation is made by cryogenic distillation.
Is mercury magnetic?
The element mercury is not magnetic except at cryogenic temperatures.
What is the definition of cryogenic surgery?
is a procedure that carefully destroys certain cells by freezing them
What is the normal phase for the element neon?
Neon, an inert gas, is a gas at non-cryogenic temperatures. A link is provided to the Wikipedia article on neon.
What are cryogenic flasks used for?
Plan ahead, into the future- ask Francoise Dorleac? pun intended long term preservation...
What is cryogenic heat treatment?
cryogenic metal treatment
What are the some example of cryogenic gases?
Any gas that liquifies below -150 degrees C is a cryogenic gas. The most popular cryogenic gas is liquid nitrogen.
What is cryogenic freezer?
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.
What rhymes with photogenic?
cryogenic :)
What has the author I Spradley written?
I. Spradley has written: 'Integrated Cryogenic Experiment (ICE) microsphere investigation' -- subject(s): Insulation, Microgravity, Microparticles, Weightlessness, Liquid helium, Cryogenic equipment, Cryogenic storage
Was some cryogenic frozen?
cryo-what!?
Is cryogenic freezing related to nitrogen?
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.
What is rocket cryogenic engines?
Rocket engine
Is xenon used in cryogenic chambers?
Not especially.
Where cryogenic valves are used?
Cryogenic valves facilitate the transfer of Liquified gas. Space industry, natural gas / petroleum, medical industry, chemicals.
Explian about cryogenic hardening?
Cryogenic hardening is often referred to cryogenic treatment and cryogenic processing. Using the term "hardening" is not correct. Cryogenic treatment does not increase the hardness of metals (I.E. rockwell hardness). Rather it changes metals on the molecular level so that they perform better. Cryogenic treatment is used for a variety of reasons including improving dimensional stability, stress relieving, increasing wear resistance, and eliminating walk and creep. A typical cryogenic treatment lasts for several days. Metal and steel parts will be put in a cryogenic processor at room temperature. The temperature will slowly be taken down to -300F below. Then it will hold there for 12 to 24 hours depending on the company doing the treatment. After that, the processor will have the temperature raised back to room temperature very slowly. Finally, the parts will be post-tempered to finalize the cryogenic treatment. Cryogenic treatment re-aligns the micro-structure of the metal to improve its structural stability. Retained austenite will be converted to martensite which allows for a tougher piece of metal. The eta-carbides in the metal will become precipitated which allows for a much higher degree of wear resistance. Below are some good sites for additional reference...
