Description

Crushing device

The present invention mainly relates to a pulverizing device, and more particularly to a pulverizing device having a pulverizing member and an air intake mechanism.

In recent years, due to the development of industry and the increase in income, refined processed foods have become the products of most people, but they may cause insufficient intake of dietary fiber. In order to supplement the insufficient dietary fiber, a variety of brewed multi-grain full shell powders have been developed.

Milling technology is an important part of the processing technology of brewing multi-grain whole shell powder. The 槌 type grinding device with screen is the most commonly used equipment in the multi-grain full-shell powder grinding technology, which has the advantages of simple structure and high grinding efficiency. However, the rake mill makes it difficult to produce smaller powdery granules for the grain having the outer shell, which causes difficulty in the production of the multi-grain full-shell powder.

In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a pulverizing apparatus capable of producing powder particles having a small size for particles having a shell and the like, and having the advantages of simple structure and high polishing efficiency.

In order to achieve the object, the present invention provides a pulverizing apparatus comprising a pulverizing tank, a rotating mechanism, a pulverizing member, and an air intake mechanism. The rotating mechanism is disposed in the pulverizing tank. The pulverizing element is disposed on the rotating mechanism, and the rotating mechanism, It is used to drive the pulverizing element to rotate around a rotating shaft. The air intake mechanism is disposed in the pulverizing tank and has one nozzle located in the pulverizing tank. The air intake mechanism is used to generate an air flow, and the air flow enters the crushing groove via the nozzle. As the comminuting element rotates and approaches the nozzle, the direction of travel of the comminuting element is substantially opposite to the direction of flow of the gas stream.

In summary, the pulverizing device of the present invention accelerates the pulverizing process by the nozzle and the pulverizing element, and can maintain the advantages of simple structure and high grinding efficiency. Further, by the direction in which the pulverizing member travels substantially opposite to the flow direction of the gas stream ejected from the nozzle, the force of the particles against the pulverizing member can be increased to pulverize the particles into smaller powdery particles.
