Breaking roll grinding mill

Abstract

The invention discloses a breaking roll grinding mill, which includes a sieve-shaped grinding base arranged on a support, wherein the sieve-shaped grinding base is provided with roll grinding sieving holes. A horizontal roll shaft is arranged over the sieve-shaped grinding base. An outer wall of the horizontal roll shaft is fixedly connected to a vertical rotating shaft. A power apparatus drives the rotating shaft to rotate. A roll cylinder is installed on the horizontal roll shaft and is tightly contacted with an upper surface of the sieve-shaped grinding base. By means of the breaking roll grinding mill, food raw materials are subjected to a cooperative effect of extrusion, friction and shearing through combination of the sieve-shaped grinding base provided with the roll grinding sieving holes and the roll cylinder. The breaking roll grinding mill is good in breaking effect by roll-grinding the food raw materials being dry, wet or oily. The breaking roll grinding mill is especially suitable for ultramicro-breaking to foods, can allow the broken foods to pass through a sieve screen being more than 300-500 in meshes, is quite significant in effects, is simple in structure and is very low in cost.

Description

technical field [0001] The invention relates to a crushing device, in particular to a 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 raw materi...

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
