Description

Technical Field

[0001] The utility model belongs to the technical field of grinders, and in particular relates to a fine grinder. Background Art

[0002] In the process of food processing and production, food additives are artificial synthetic substances or natural substances added to food to improve the color, aroma, taste and other qualities of food, as well as for preservation and processing technology requirements. In specific use, most food additives are added to food after grinding and refining. Different food additives require different degrees of refinement to achieve better results. In the existing technology, it is not easy to adjust the degree of grinding and refining when grinding food additives, resulting in low work efficiency; or multiple grinding equipment is required for grinding operations, resulting in high costs.

[0003] The patent with application number 202122146336.7 discloses a food additive grinding device, which has a shell, and the shell is a hollow structure. A power motor is installed in the upper part of the shell, and an upper grinding block is connected below the power motor. A lower grinding block is provided below the upper grinding block, and the lower grinding block is mounted on a lifting slide bar. A fastening handle is provided on the lower grinding block, and the bolts on the fastening handle pass through the shell and the lower grinding block and are supported on the lifting slide bar; the shell is provided with a feed port on one side. When in use, the distance between the lower grinding block and the upper grinding block is adjusted according to the degree of grinding refinement required for the food additive. The smaller the distance between the upper grinding block and the lower grinding block, the finer the food additive ground out. During adjustment, the bolt connected to the fastening handle is rotated, and the bolt leaves the lifting slide bar, and the lower grinding block can slide up and down on the lifting slide bar.

[0004] Although the above technical solution adjusts the grinding gap through the adjustable lower grinding block, since the particles of food additives are small, insufficient grinding will occur when the grinding gap is too large, while excessive grinding of the grinding particles will result in excessive grinding of the grinding particles. In addition, since the grinder lacks filtration of the grinding particles, particles of different sizes will pass through the grinding block after being squeezed, resulting in poor accuracy in adjusting the size of the grinding particles. Utility Model Content

The knob 2 is held by hand to drive the screw 12 to rotate (in order to avoid the need for the two knobs 2 to rotate synchronously at the same speed, the support frame 7 is split into two arc plates, which can be driven by the two knobs 2 respectively 7 is lifted and lowered), and in the process of rotation, the support frame 7 is driven to move downward, and in the process of movement, the gap between the support block and the grinding block 10 is increased, thereby increasing the amount of ground food additives, which is suitable for fast grinding of soft raw materials. When food additives of different particles need to be processed, the fastening block 17 is squeezed to shrink it into the mounting groove 15, which is convenient for disassembly and replacement of the screening plate 8. When the screening plates 8 of different apertures are replaced, the spring 16 in the mounting groove 15 at the bottom end of the connecting rod 13 pushes the fastening block 17 to abut against the bottom end of the screening plate 8, so that the screening plate 8 remains fixed, which is suitable for grinding and screening of food additives of different particles.
