What is meant by cryogenic grinding?

Cryogenic grinding, also known as freezer milling, freezer grinding, and cryomilling, is the act of cooling or chilling a material and then reducing it into a small particle size. For samples that are soft or flexible at room temperature, cryogenic grinding may be the only viable technique for processing samples.

What is cryogenic grinding of spices?

Cryogenic Grinding is the technique of pulverizing spices and herbs at sub-zero temperatures (-17.78°C), to minimize the loss of essential oils. When grinding is done through cryogenic technique, integrity and quality of the spices remain intact. The result is natural colour, taste and aroma retained in the spices.

Is cryo grinding of spices better than conventional grinding?

It was found that cryogenic grinding retained 62.56% more volatile oil as compared to ambient grinding. On the basis of retention of volatile oil, the premium quality cumin powder was obtained at grinding temperature −30 °C with a feed rate of 7 kg/hr and sieve size of 0.8 mm.

Why is cryogenic grinding used?

Cryogenic grinding is a process used in various manufacturing industries and in the study of biology. Also known as freezer milling or freezer grinding, this method is used to process soft or flexible substances by lowering the material’s temperature and then breaking the material into smaller particles.

What is the traditional method of grinding of spice?

There are two easy ways to grind spices: first, a mortar and pestle. Or use a spice grinder. When grinding spices that are similar in size, grind them together and save a step. Tip: Cumin, coriander and bay leaves are often used together in many cuisines.

Why Liquid nitrogen is used in cryogenic grinding?

The quality of ground powder may be maintained by cryogenic grinding technique using liquid nitrogen that provides the refrigeration needed to pre-cool the spices and maintain the desired low temperature by absorbing the heat generated during the grinding operation.

Is it cryonics or cryogenics?

is that cryogenics is the science and technology of the production of very low temperatures while cryonics is the cryopreservation of a person with medical needs that cannot be met by available medicine until resuscitation and healing by future medicine is possible.

How is cryogenics used today?

Cryogenics is used in a variety of applications. It can be used to produce cryogenic fields for rockets, in MRI machines that use liquid helium and require cryogenic cooling, storing large quantities of food, special effects fog, recycling, freezing blood and tissue samples, and even cooling superconductors.

What temperature is liquid nitrogen?

Cryogenic liquids are liquefied gases that have a normal boiling point below –130°F (–90°C). Liquid nitrogen has a boiling point of –320°F (–196°C). The temperature difference between the product and the surrounding environment, even in winter, is substantial.
