temperatures which create a lot of heat during grinding. Temperature ranging from 42°C-95°C, leads to the loss of flavor, aroma and volatile oil of the ground powder (Das, 2005). Moreover, the fat content of the spice poses problems of temperature rise; spices reduce a significant fraction of their volatile oil or flavoring components.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 Design of a cryogenic grinding system for spices

1 The heat is developed inside the grinding mill Temperature below 0 o C inside the grinding mill 2 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 3 This in turn can lead to the grinding elements Fig. 33. 2 Grinding spices in Stone and Plate In the old days methods of grinding spices are different. Before electric blenders, the spices were grounded manually. Every house had their own pestle and mortar made of undressed granite. This was used for grinding small quantities of spices for home-scale usage 33.2.1 GrindersModule -33: Grinding Methods INFLIBNET Centre

Practical Low-Temperature Size Reduction. June 1, 2014. 13 Min Read. size reduction lab. Size reduction of solid materials may be one of the most important technologies in the modern world. Coal that is pulverized to the size of talcum powder fuels the generators that supply over 45% of the electric power in the U.S. and over 40% For larger scale production a small, powered grinding mill is needed and models are available that can grind 25kg/hour. A grinding mill needs to be placed in a separate and well ventilated room because of the dust. Great care is needed to ensure uniform sized pieces/powders after grinding and also to prevent heating of spices during Spice Processing (Practical Action Technical Brief) Appropedia

Because cryogenic grinding reduces the loss of essential oils (approx. 3 10 % loss) in comparison to grinding at ambient temperature (approx. 15 43 % loss), it is possible to improve the aroma and flavour. The grinding performance is about twice as high, and the risk of fire is eliminated. Cryogenic grinding plant with UPZ 100 14 IThe extremely low temperature is maintained during grinding which allows condensation of the volatile matter and helps retain their presence in spices. This process involves the use of high-pressure liquified CO2 stored in a cylinder which is released at the atmospheric pressure to form carbonic snow/dry ice.Managing thermal damage during spice grinding
