Deep freezer is used for freezing storage of biological specimens, samples, materials and reagents at ultra low temperature in institutes, universities and laboratories related to research in the fields of life science, biological engineering, agriculture and animal husbandry; also used for low temperature tests and cold treatment of chemical material, electronic components, metal parts and special materials in Industries of Chemical, Electronics, Mechanical Manufacturing, Shipbuilding, War Industry, Aeronautics & Astronautics etc.
Difference between freezing and deep freezing
The terms “freezing” and “deep freezing” originally referred to two different methods of preserving food. Both processes freeze the food to the same temperature (-18 °C), but they achieve it in two different ways. With freezing, the temperature of the food is decreased slowly, usually up to 24 hours. Deep freezing refers to a process where the food is exposed to a temperature from -30 °C to -50 °C so that the core of the product reaches -18 °C within an hour. Deep freezing is a method typically used in industrial settings. It is considered to be better than regular freezing in allowing the food to preserve its freshness, texture and nutritional qualities.
How the Deep Freezers work?
Mechanical or single compressor based freezers can easily reach the temperature range -40 degree Celsius or -60 degree Celsius. Apart from that a freezer which is equipped with two compressors are used to create the temperature below the mentioned limit. To utilize the efficiency of the compressors and to extend the life of the compressors, the small compressors automatically get turn off whenever the set temperature is reached whereas the big compressor should remain On continuously for maintain the consistency in temperature.
