Herbs & Spices

Spices are an essential element of cuisine, yet during grinding, heat often causes the loss of aroma and flavor. Messer’s liquid nitrogen cryogenic grinding technology provides an innovative solution to this challenge. By mixing food-grade liquid nitrogen with oil-rich spices before grinding, and precisely adjusting the nitrogen dosage through a dedicated temperature-control system based on the outlet temperature of the material, the process not only locks in essential oils and aromatic compounds but also produces ultra-fine powders with a uniform particle size distribution. The combination of liquid nitrogen and cryogenic grinding demonstrates the distinct advantages of this advanced process.

• Ultra-fine powder yield improved by 80%, with essential oil and aroma retention enhanced by more than 30%.

• Protects heat-sensitive materials by preventing thermal damage, while the inert gas environment effectively reduces oxidation of vitamins and proteins.

• Effectively prevents dust explosions, reduces equipment blockages, improves production efficiency, and lowers maintenance costs.

Compared with other suppliers, Messer’s cryogenic grinding technology delivers more than double the output while cutting liquid nitrogen consumption by 50%, offering an efficient, high-quality solution for spice processing.
