Grinding head with stone grinding surface

Abstract

The invention discloses a grinding head with a stone grinding surface. The grinding head comprises a movable grinding head and a static grinding head which sleeve together, wherein the movable grinding head and the static grinding head are in meshing transmission by means of a gear grinding set, a joint of tail parts of the movable grinding head and the static grinding head is ground by means of the stone grinding surface, the movable grinding head rotates, materials are crushed and primarily ground by the movable grinding head and the static grinding head under the action of a centrifugal force, and enters the stone grinding surface after being ground and primarily ground, the stone grinding surface can generate a friction force in a grinding process, thus the grinding and pulverizing effect is improved. Wheat germ and flour are combined together, thus flour containing multi-vitamin nutrients integrally in the wheat is realized. Because a stone filler only accounts for one small part of the movable grinding head and the static grinding head, when the grinding loss is serious, the movable grinding head and the static grinding head can be dismantled, and the stone filler is adhered in respective toothed grooves continuously by using an adhesive so that the stone filler can be continuously used, thus the production cost is greatly reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a flour processing equipment, in particular to a grinding head with a stone grinding surface. Background technique [0002] In food processing, grains such as wheat need to be processed into flour. At present, the equipment for processing flour is mainly the double-roll technology, which is also the most advanced general-purpose technology in the world. This technology uses a wind transport system in the flour extraction process, and its biggest weakness is that the germ is not in the flour. Because the proportion of germ is much lighter than that of endosperm, flour mills of a certain scale have extracted wheat germ before milling. So the flour that prior art produces does not contain germ. [0003] After more than 20 years of research, we have proved that vitamin A, the nutritional ingredient contained in wheat germ, directly affects children's vision, and vitamin E has a strong active tissue, which is related to the ferti...

Problems solved by technology

[0006] Aiming at the above-mentioned defects of traditional stone mills, many stone mills driven by electricity have appeared on the market, for example: the patent No. ZL2013207139016, the patent named automatic stone mill flour machine, is based on the traditional stone mill. The electric drive device greatly improves the production efficiency. However, since the stone mill is made of stone, its hardness and wear resistance are much lower than that of the machine-made grinding head. Especially after the electric drive device is added, the speed is greatly increased. At the same time It also speeds up the wear of the stone mill. Since the upper grinding head and the lower grinding head of the traditional stone mill are chiseled as a whole, when the grinding teeth are worn out, they cannot be repaired and the grinding head can only be replaced, which is a great waste of time. Resources increase the production cost of flour. At the same time, because the grinding disc is made of various stone materials, some of which contain harmful substances to the human body. During the grinding process, a large amount of stone waste is mixed into the flour. If consumed by humans or animals, it will have adverse effects on the health of the body
