cryogenic safety hazards are reduced to as low a level as is reasonably achievable. This will entail (1) a safety analysis and review for all cryogenic facilities, as described in Section 3, (2) cryogenic safety and operational training for relevant personnel, (3) upkeep of appropriate maintenance and inspection schedules and records.

Cryogenic temperature range has been defined as being between -238ºF (-150ºC) and absolute zero, which is -459.67ºF (-273.15ºC). Cryogenicists are responsible for studying the behavior of various materials and matter within this temperature range.

The average cost of the treatment is generally 15% of the tool cost. When properly applied, cryogenic treatment also has the potential to decrease processing costs and improve part quality. The key is to integrate cryogenics into the heat-treatment cycle rather than to use it as an "added-on" process. About the Authors

Cryogenic cooling generates 50% lower grinding energy compared to dry grinding, and 31% compared to wet grinding at a depth of cut of 10 μm. The lower energy contributed by cryogenic cooling, is due to the lower work softening, lower grinding forces, retention of grit sharpness and favorable chip formation [14].

The word cryogenic refers to very low temperatures. Cryogenic Grinding is the technique of pulverizing spices and herbs at sub-zero temperatures (-17.78°C), to minimize the loss of essential oils. Using liquid Nitrogen vapour blanket or Nitrogen gas circulation, a dry and cold atmosphere is created which does not react with the spices.

The cryogenic grinding system consists of two units, Pre-cooling Unit, and Grinding Unit. These units introduce liquid nitrogen into the barrel and remove the heat from the material before it enters into the grinder. By the use of low temperature, the raw materials become brittle, which causes the fibers to shatter.

Cryogenic Grinding is also known as cryo- milling is a process of cooling a material to a low temperature and then reducing the dimensions of the material. Once cooling is completed, the material becomes em-brittle i.e. the material loses its ductility. The cryogenic Grinding process involves two units i.e. precooling unit and grinding unit.
