What are Cryogenic Spices ?

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. Standard grinding process which does not use a cooling system can reach up to +200°F. This high temperature can reduce volatile components and heat sensitive constituents in spices

Superiority of Cryogenic over Standard Grinding Systems

Traditional Grinding System	Cryogenic Grinding System
The heat is developed inside the grinding mill	Temperature below 0*c inside the grinding mill
The heat, which is developed during grinding, leads on one hand to evaporation of the essential oil and on the other hand, heat sensitive fats are melted.	Negligible loss of volatile component
This in turn can lead to the grinding elements become greasy (oily) and even harms the machine by blocking it.	Not in Cryogenic process
High energy consumption	Low energy consumption
High capacity motors are required to grind the material	Low capacity motors are required to grind the material
Essential value of material are evaporated	No evaporation of essential value
No control on particle size	Particle size are under controlled
