Objective

This is a new concept in spices processing, which results into higher production with better end product quality aroma and color, than conventional spices grinding unit. This technology uses liquid nitrogen to control the grinding chamber temperature, the result of which is reduction in loss of volatile essential oils in the spices and higher production rate.
This spice grinding is relatively very advanced technology and hence there are very few units operating at present in India.

Manufacturing process

As indicated previously-This spices grinding technology is new to India, which necessitates import of technology from developed countries like Japan and Germany. This grinding technology reduces the material to particle sizes, which is difficult to attain with ambient temperature grinding in conventional grinding plants. The dry, cold, inert atmosphere, usually generated by a Liquid nitrogen vapor blanket or circulation in the grinder chamber, minimizes thermal reaction with the material and reduces the loss of volatile components from spices during processing.


The advantages offered by this spices grinding technology as against conventional spices grinding technology are as under:

 This grinding technology improves the aroma by minimizing the loss of essential oils (approx.3% loss) which is approx 43% in conventional processing. This is important for Cumin processing. Spices are ground to a thickness of 50 microns, as compared to a size range of 500 – 1000 using conventional grinding processes.

 Spices processed using liquid nitrogen for grinding has better natural color, as compared to conventional process, this is very much important for Chilly and Turmeric.

 Finer particle size can be achieved without aroma loss and natural color change.


 Overall grinding capacity can be increased by 2 to 3 times, as process equipments will not have thermal fatigue due to heating up. Fire risks too, are eliminated as temperature during processing is controlled.

 This method of grinding enhances unlocking of natural flavors, aid easy dispersion of the same and control flavor strength.


Plant and Machinery

The major machineries required are blower, rotary filter, cooler with liquid nitrogen supply, impact mills, filter etc.

Source of Machinery / Technology

It is important to note here that this spices grinding technology is not available in India at present and there will be need to import it from either Japan or Germany.

Dear Manoj,
I think, he is talking abt cyro grinding. There are few units in kerela with imported machinery. CFTRI has this prototype and you can visit to get more details.

Though stands out on quality, cost of this machine is high compared to the conventional grinding mill.

New grinding

Dear sir,
Need to be established with comparative study olfactory/taste along with chemical analysis (GLC/Mas Spectra) and finely the yield/ because ofCost factor. All essential oils need to be standardization( chemical composition and olfactory) By theory it sounds good but stood studied all para meter before going for it.
All what new process develop in European country's are not implementable.
