A kind of superfine crushing roller milling

Abstract

The invention discloses a roller mill for ultra-fine crushing, which comprises a sieve-shaped grinding disc arranged on a support, a roller mill sieve hole is opened on the sieve-shaped grinding disc, and a horizontal roller shaft is arranged above the sieve-shaped grinding disc. The outer wall of the roller shaft is fixedly connected with a vertical shaft, and the vertical shaft is driven to rotate by a power device. A roller is installed on the horizontal roller shaft, and the roller is in close contact with the upper surface of the sieve-shaped grinding pan. The remarkable effect of adopting the present invention is that, through the cooperation of the sieve-shaped disc and the roller provided with the roller milling sieve holes, the food raw materials are extruded, rubbed and sheared synergistically, and the dry, wet or oily food The raw materials are rolled and crushed, and the crushing effect is good. It is especially suitable for ultrafine crushing of food. The finished product can pass through a sieve of 300-500 mesh or more. The effect is very significant, and the structure is simple and the cost is very low.

Description

technical field [0001] The invention relates to a crushing device, in particular to a superfine crushing roller mill. Background technique [0002] Crusher is widely used in food industry, traditional Chinese medicine pharmaceutical industry, fine chemical industry and biotechnology industry and other fields. In the food industry, the particles of ultrafine food are very fine, the surface area is large, and they have excellent functional properties and taste. Therefore, ultrafine crushing equipment is required in the manufacturing process of many foods. For example, in the production of insoluble dietary fiber, due to the coarse particles of the fibrous component, the taste is rough and difficult to swallow. If it is subjected to ultra-micro treatment, this problem can be solved, so that people feel both in the mouth and in the lower throat. Comfort; in addition, when making peanut butter, sesame or soybean milk powder, it is also necessary to perform ultrafine crushing on ...

AI Technical Summary

Problems solved by technology

When grinding is required, due to the low specific gravity of food raw materials, the smaller the particle size, the lighter the weight, it is easy to float in the air, and it is difficult to be further broken by collision, and the grinding effect is not good.

And the small particle size food fine powder that above-mentioned these machinery obtains is far from reaching ultrafine standard (being able to cross more than 300 mesh, or the diameter of powder particle is less than 48 microns)

When it is necessary to grind thick sauce with high viscosity, for example, when grinding oilseeds with high oil content, the above-mentioned machines are even more incompetent, so the existing above-mentioned so-called ultra-micro devices are not suitable for the food industry

[0004] In the current ultrafine food production process, colloid mills are used to ultrafinely crush raw materials, but colloid mills are only suitable for situations with particularly high water content or high oil content and good fluidity. Adding a large amount of water to the raw materials, grinding and crushing, and then dehydrating and drying the raw materials, the processing is very inconvenient; colloid mills cannot dry process food raw materials, and the cost of colloid mills is generally high

[0005] The disc of the traditional roller mill is flat, relying on the gravity of the drum, the material is squeezed and rubbed between the drum and the disc to be crushed, but its crushing capacity is limited and the grinding effect is not good
