spice flavor retains during grinding process. Definition Cryogenic grinding of spices is a method of powdering spicesherbs at sub zero temperatures ranging from 0 to minus 196 0C.the spices are frozen with liquid nitrogen, as they are being ground. This process does not damage or alter the chemical composition of the spices in any way.
Mar 01, 1999 Therefore, a cryogenic grinding system was designed and developed to cool the spices before feeding to the grinder and also maintain the cryogenic temperature in the grinding zone. The main components of the cryogenic grinding system are a precooler and grinder. ... The main aim of spice grinding is to obtain smaller particle size with good ...

Spices Cryogenic grinding unit is a new concept in spices processing, which results in higher production with better end product quality aroma and colour, than conventional spices grinding unit. This technology uses liquid nitrogen to control the grinding chamber temperature, the result of which is a reduction in loss of volatile essential ...
Cryogenic grinding is a process of mixing Liquid Nitrogen with a spice to lower the temperature up to -190 degrees C, then grinding the super-cooled product. This type of grinding system protects spices essential oils and other vital constituents that could be lost during conventional grinding.
The loss of volatile oil can be significantly reduced by cooling the spices before feeding to the grinder and also maintaining the ultra-low temperature in the grinding zone. In cryogenic grinding, liquid nitrogen, having boiling point of -195.6C, provides the refrigeration needed to pre-cool the spices and maintain the desired low temperature by absorbing the heat generated during the grinding operation.
The fat content of spices poses problems of temperature rise and sieve clogging during grinding. Due to this temperature rise, spices lose a significant fraction of their volatile oil or flavouring components. Therefore, a cryogenic grinding system was designed and developed to cool the spices before feeding to the grinder and also maintain the cryogenic temperature in the grinding zone.

Cryogenic grinders generally consist of precoolers and grinder with the cryogen distribution system. In such grinding systems, cryogens subject the raw material up to or lower than glass transition temperature before it is ground, thus eliminating much of the material and quality hassles of traditional grinding.
Mar 01, 2008 As quantitative data on cryogenic grinding of spices are scarce, there is a need to know the grinding characteristics by employing this system of grinding. Black pepper is a common spice produced in Oriental countries mostly in southeast Asia but is used world wide for its characteristic pungent flavour and taste.
