·Cryogenic grinding generation can correctly grind maximum tough materials and can also facilitate Cryogenic recycling of tough composite materials and multi component scrap The coronary heart of this era is the CRYO GRIND SYSTEM It employs a cryogenic technique to embrittle and grind materials to achieve
·Cryogenic size reduction can provide benefits for many processing applications including thermoplastics and spices Surprisingly these disparate applications have key attributes in common that cryogenic grinding effectively addresses Cryogenic Grinding A Multitasking Marvel From spices to thermoplastics cryogenic size reduction
The development of a pilot plant for cryogrinding of spices is discussed in this paper The unit has an indigenously designed and developed cryogenic screw cooler for optimal utilization of liquid nitrogen along with a digital signal processing system DSP for liquid nitrogen spray and automatic temperature control
The main aim of this review is to summarize the knowledge of size reduction theory in grinding working and importance of cryogenic grinding over convention method Conventional grinding methods can be used to grind the species but the problem of increase in the temperatures during grinding may lose the volatile oil compounds natural flavour and aroma But in cryogenic
Heat is generated during the grinding process which has two consequences Firstly the essential oils evaporate and secondly the heat sensitive fats melt In the worst case this can cause the grinding elements to clog up and the entire mill to block and stall This is prevented by cryogenic grinding with mainly liquid nitrogen as a cooling
·Grinding is a vital step in the postharvest processing of spices therefore requires special attention to preserve the aroma and flavor compounds present in them During grinding the overall temperature increases significantly which results in loss of a considerable fraction of their volatile oil or flavoring components in spices
·The scenario and application of cryogenics in different sectors especially to spice grinding is reviewed which shows a promising pathway to produce higher quality end product with higher flavor and volatile oil retention Cryogenics is the study of very low temperature and its application on different materials including biological products Cryogenics
Cryogenic grinding of herbs and spices involves powdering these elements at sub zero temperatures ranging from 0 to 196°C The elements are frozen with liquid nitrogen as they are being ground This process does not damage or alter the chemical composition of the main elements in any way
