Description

Technical Field

[0001] The utility model relates to the technical field of flour milling equipment, in particular to a food flour milling and screening equipment. Background Art

[0002] In the field of food processing, especially in the process of flour milling and screening of grain foods, traditional methods usually adopt a series of independent devices to carry out flour milling and screening operations in sequence. These devices often have the following disadvantages: First, the production efficiency is low because the materials need to be transferred between multiple devices, resulting in an extended processing cycle; second, the equipment occupies a large area and is not convenient for integrated production; third, the energy consumption is relatively high, and dust is easily generated during the processing, which has an impact on the health of workers and the environment.

[0003] A screening flour mill disclosed in a Chinese patent with the publication number CN213161277U includes a flour mill body. A hopper is provided at the front end of the flour mill body, and a bracket is provided at the upper end of the flour mill body. The bottom end of the bracket is fixedly connected to the flour mill body by screws, and a screening mechanism is provided at the upper end of the bracket. The screening mechanism includes a housing. The housing is in a right-angled shape. An inlet is provided at the top of the housing, and an outlet is provided at the lower end of the housing. A fixed frame is provided at the upper end of the housing. One end of the fixed frame is rotatably connected to the housing through a rotating shaft, and a connecting block is provided at the other end of the fixed frame. One end of the connecting block passes through the housing. A filter screen is provided inside the fixed frame, and a fixing plate is provided at the upper end of the fixed frame. Compared with the traditional screening flour mill, this patent has the advantages of simple structure, easy maintenance, and the ability to screen and remove impurities from materials.

[0004] Based on the above search and in combination with the prior art, it is found that:

[0005] The existing device can make the fixed frame vibrate continuously through a driving motor and a cam. When the material falls on the fixed frame, on the one hand, the material can be screened through the filter screen on the fixed frame, and on the other hand, the filter screen can also play a role in dividing the material. However, after the material is ground and processed, there are various materials with different sizes mixed together, and these materials need to be separated through multiple layers of screening. The existing device can only perform single screening through a single filter screen, and there will still be materials with different sizes mixed together, which has limitations in use. Content of the Utility Model

[0006] To solve the above technical problems, the present utility model proposes a food grinding and screening device. Under the joint action of the vibrator and multiple springs, the first screening box can be driven to vibrate, achieving the effect of screening the materials in the first screening box. Similarly, the materials continue to be screened through the second screening box and the third screening box, and the materials of the final required size are screened and dropped into the collection box. This device screens different-sized materials in the mixed materials completely through a multi-layer screening method.
