Description

Technical Field

[0001] The utility model relates to the technical field of fiber grinding, in particular to a fine grinding device for fruit and vegetable fibers. Background Technique

[0002] In the existing fruit and vegetable processing technology, for the grinding treatment of fruit and vegetable fibers, the traditional method mainly uses a high-speed rotating blade for cutting to achieve the purpose of pulverization. However, this method has many deficiencies. First, due to the high-speed rotation of the blade, it is easy to cause the loss of nutrients in the fruit and vegetable fibers, affecting the quality of the powder. Second, the high temperature generated during the cutting process easily causes the fibers to denature, reducing the activity of the powder. In addition, during the processing by the traditional method, it is difficult to precisely control the particle size of the powder, resulting in poor uniformity of the powder.

[0003] A Chinese patent with the publication number of CN213050902 discloses a fine grinding device, which includes a machine body and a processing box. The processing box is installed on one side of the outer wall of the machine body through a connecting pipe. One side of the bottom of the processing box is connected with a discharge pipe, and the upper end of the connecting pipe is welded with a feed pipe. One side wall of the processing box is installed with a coarse-fine regulating valve. The middle of the feed pipe is welded with an intermediate pipe integrated with it. The middle of the intermediate pipe is welded with a fixed disk. A plurality of material channels are evenly arranged inside the fixed disk, and a hollow central shaft is welded in the middle of the fixed disk. A middle cavity is also arranged in the central shaft. A rotating knife is rotatably installed in the middle cavity through a first motor, and knives are rotatably arranged on both the upper surface and the lower surface of the fixed disk. Compared with the prior art, this patent greatly improves the grinding efficiency of the device and also reduces the probability of jamming inside the machine.

[0005] The existing device has multiple material channels opened in the fixed disk, a rotating knife is installed inside it, and knives are also installed on both its upper surface and lower surface. The rotating knife and the knives are used for rotating cutting at the ports and inside the material channels. However, the existing device can only cut the material into smaller pieces through the rotating cutting of the rotating knife and the knives. If powdery material needs to be produced, grinding is required. The existing device cannot achieve the grinding effect and has limitations in actual production. Content of the Utility Model
