Method for crushing spices

Abstract

The invention discloses a method for crushing spices. The method comprises the following concrete steps: sending the spices to low-temperature extrusion-grinding crushing equipment; and grinding the spices into superfine powder at a low temperature by adopting a jacket filled with a cooling medium. The low-temperature grinding micro-crushing method for the spices, disclosed by the invention, can be used for achieving mechanical processing; in comparison with a traditional universal crushing method, the method disclosed by the invention has the advantages that materials which are hard to crush at the normal temperature can be crushed, the small material temperature increment is caused during crushing, and the freshness, color, flavor, taste and various active substances of the powder material can be retained, so that the method is especially suitable for crushing the spices which are relatively high in content of volatile components; the processing quality of the spices is greatly guaranteed; the superfine degree of a processed product has incomparable advantages.
