Carbon di-oxide with its varied inherent properties suits the spices industry.

In spices industry Co₂ finds its way in the grinding technology.The Cryogenic Fine Grinding Technology is based on use and injection of liquid Co₂ in the grinding chamber for grinding process. Advantages of Co₂ in grinding technology are:

1. By utilizing the cooling power of liquid Co₂ , the toughest of materials can be ground to particle sizes below 200 micron.
2. liquid Co₂ to regulate the heat of the grinding mill and allow higher material throughputs at any time of year.
3. liquid Co₂ has the advantage that it cools directly during the grinding process. i.e. The Co₂ snow arising by the nozzle injection into the grinding chamber mixes with the product during the grinding process, thus preventing it from heating during grinding. This means that the cooling agent only eliminates the heat of the grinding process, the product leaves with almost the same temperature as it has entered.
4. liquid Co₂ rises the cold spontaneously during nozzle injection, so that the product is embrittled superficially and, thus, has a better grinding behavior.
5. In case of liquid Co₂, the grinding can be started at once.
6. With regard to consumption, liquid Co₂ needs almost the same quantity as L-N2.
7. It is possible to spray liquid Co₂ directly through a nozzle so that the coldness is provided directly behind the nozzle.
8. Machines using liquid Co₂ need to be made with ordinary carbon steel / stainless steel, it will be much cheaper compared to L-N2 where the machines must be of aluminum.
9. Batch Cooler needed for the usage of liquid N2 is very expensive – which will push the cost of the machine; liquid Co₂ does not require this cooler.
10. When compared with conventional grinding plants liquid Co₂ has the following advantages:

¨ Higher flavour content
¨ Inertising inside the plant (protection against fire or dust explosions)
¨ No entrance of air humidity
¨ No entrance of germs and bacteria during the grinding process.
¨ Less cleaning time without big filter
¨ Less consumption costs through gas circulation
¨ Less plant costs through the compact plant

11. Advantages liquid Co₂ grinding compared with deep temperature Grinding plants (L-N2)

¨ No pre-cooling of the plant
¨ No pre-cooling of the product,
¨ No thawing of the product
¨ No special material of the plant necessary
¨ No isolation necessary

Advantages of using solid Co₂ ( dry Ice) in spices grinding

1. If the grinders can not afford the extra investment on these machineries like, nozzle needed for spraying liquid Co₂ , then dry ice is the only option.

2. REDUCES THE HEAT - REQUIRING JUST 30 MINUTES OF COOLING (AS AGAINST 120 MINUTES)

3. RETAINS AROMA AS FINISHED PRODUCT COULD BE PACKED AFTER 30 MINUTES OF DRYING / COOLING

4. NORMAL COLOUR IS RETAINED

5. DRYING FLOOR REMAINS COOLER AND HENCE READY FOR NEXT BATCH.

6. HIGHLY ECONOMICAL ie Rs. 1.20 OF DRY ICE IS REQUIRED FOR ONE KG OF GROUND SPICE POWDER.

7. DOES NOT REQUIRE EXPENSIVE MACHINERY AND CAN BE DONE WITH THE STANDARD CONVENTIONAL GRINDING MACHINES.
