Equipment Introduction

Low temperature grinding machine for spices is a process of grinding spices at extremely low temperatures (usually from liquid nitrogen) below zero degrees Celsius.

This technology can prevent the heat generated during traditional grinding from damaging the delicate volatile oils that give spices their unique aroma and flavor, thereby producing a final product that is more intense and closer to the original flavor.

The problem of traditional grinding

The influence of heat on volatile oils

Heat is the main enemy of the characteristics of spices. Most of the aroma and flavor in spices are contained in their volatile oils, which are highly sensitive and easily evaporate when heated.

Aroma and flavor degradation

As these oils are lost during the high-temperature grinding process, the resulting spice powder has lower efficacy and less complexity compared to its original intact form.

Uneven grinding

Spices with high oil content or moisture content will become thick when heated, resulting in uneven grinding and the appearance of large, undesirable spots.

How Low temperature grinding machine for spices delivers superior quality

The effect of extremely low temperatures

The spices are rapidly frozen using liquid nitrogen, cooling them to below zero degrees. This makes the spices extremely brittle and glass-like, eliminating any stickiness.

Maximize the retention of volatile substances

As the entire process takes place in an inert, ultra-cold environment, the loss of volatile oils can be negligible. The aroma and flavor are locked within the spice powder and do not escape into the air.

More fine and consistent granularity

The brittleness of frozen spices enables them to be ground into fine and extremely uniform powder. Low temperature grinding machine for spices ensures the even distribution of flavor when added to food and results in a smoother texture.
