Description

Technical Field

[0001] This utility model relates to the field of premixed powder processing technology, specifically a premixed powder processing pulverizer. Background Technology

[0002] Premixed powders are baking ingredients that are pre-mixed according to a recipe. They are made from a variety of complex food materials using professional methods to reduce the skill and difficulty of baking and lower the failure rate. Many baking companies currently use premixed powders to make bread and cakes.

[0003] When processing premixed powder, the raw materials need to be crushed into powder and then mixed in proportion. The processing and manufacturing of premixed powder requires crushing multiple raw materials. After one raw material is crushed, the powder discharged from the first batch of raw materials when crushing the next raw material will contain residual powder from the previous raw material, resulting in impurities in this part of the powder. Therefore, the crushing chamber needs to be cleaned after each raw material is crushed. However, existing crushers require opening the crushing chamber after crushing the raw materials to thoroughly clean the inside, which is cumbersome and difficult to clean quickly. Therefore, a crusher for processing premixed powder is proposed.

[0004] For example, Chinese patent CN117718104A discloses a pulverizer for processing premixed powder, including a box and a support table. The box is assembled at the center of the support table. The box is equipped with a grinding and pulverizing mechanism. The support table is equipped with a cleaning mechanism that communicates with the box. The cleaning mechanism includes an air guide pipe. The air guide pipe is L-shaped at the upper end of the support table and is set along the edge of the box. One end of the air guide pipe is connected to a fan, and the other end of the air guide pipe is connected to an air inlet pipe that communicates with the upper side of the box. A cylindrical impact chamber is provided at the corner of the L-shaped air guide pipe. An impact groove is connected between the inside of the box and the impact chamber. The impact groove is equipped with a bearing block that is connected to the grinding and pulverizing mechanism and extends into the impact chamber. A rotating rod is rotatably assembled at the center of the impact chamber. Several wind vanes matching the bearing block are distributed around the outer circumference of the rotating rod. An elastic sealing ring is provided between the inner wall of the impact groove and the bearing block. By setting a fan to blow air into the inside of the box to discharge the material, the device can be cleaned and discharged without being disassembled and opened.

[0005] However, it is difficult to completely clean the raw materials adhering to the inner wall of the equipment by simply using impact vibration, and impact vibration will also generate a lot of noise, affecting the production environment. Utility Model Content
