Bistrique material is constituted.
Background technology
The mode that now particulate species flavouring is crushed substantially has three kinds：A kind of entered in traditional mode such as smash to pieces
Row grinding；One kind is taken at any time after flavouring is largely crushed；Another is to measure to grind at any time as needed.These three
In mode, traditional approach grinding is wasted time and energy, and the equipment smashed to pieces is larger, in-convenience in use.Flavouring is carried out into a large amount of powder
The mode that can be taken at any time after broken, it is upper relatively simple from using, but the shortcoming of this mode is after flavouring is pulverized, to break
The guard system of former flavouring is broken, causes oxidation reaction to be accelerated, easily made flavouring reduction or lose its effect.In order to change
The shortcoming of above two flavouring grinding mode, is widely used with a kind of Manual polisher with mill now.And this
