Description

Grinder with feed screw

The invention relates to a grinding machine with a feeding screw, in particular to a grinding machine which can be used for grinding tea leaves (including strip tea leaves, spherical tea leaves), coffee beans and the like.

Conventional coffee bean grinders usually have a conical container filled with coffee beans. When the grinder is activated, the coffee beans are freely falling down to the grinding cutter disc, and the grinding discs with the grinding pitch are adjusted to grind the coffee beans into appropriate thicknesses. Coffee powder is used for subsequent brewing procedures.

When the grinder is used to grind tea leaves, the appearance of the tea can be roughly divided into spheres and strips due to the variety of tea leaves. Since the tea leaves are crops, the appearance of the same batch of tea products is also uneven. When grinding tea leaves, especially strips. Tea leaves often create bridging conditions in cone-shaped containers, affecting the downward flow of tea leaves, causing the tea grinding process to stop.

In summary, the present inventors have felt that the above-mentioned defects can be improved, and the present invention has been put forward with great interest in designing and coordinating the above-mentioned defects.
