High-efficiency low-temperature wheat squeezing-cutting smashing milling process and milling device

Abstract

The invention discloses a high-efficiency low-temperature wheat squeezing-cutting smashing milling process which comprises a shelling process, a sizing process, a reduction process, a tail grinding process and a purifying process. In the shelling process, four times of shelling are carried out, in the sizing process, two times of sizing are carried out, and in the reduction process, four times of reduction are carried out; a high-speed squeezing-cutting smashing machine is adopted for the third shelling, a minimum gap between a rotor pin and a stator pin of the high-speed squeezing-cutting smashing machine is 0.3 to 1mm, and a linear speed of the rotor pin on the outermost circle is 30m / s to 70m / s; the high-speed squeezing-cutting smashing machine adopted in the third shelling machines coarse bran flake produced in the second shelling. The invention further discloses a milling device using the high-efficiency low-temperature wheat squeezing-cutting smashing milling process. According to the invention, the milling process is redesigned; the third shelling, the fourth shelling and the first sizing adopt the high-speed squeezing-cutting smashing machine; a reduction system adopts a water-cooling high-speed squeezing-cutting smashing machine; germ extraction is carried out in the second sizing, so that a germ extraction rate of a production line is improved by at least twice, flour accuracy and a total flour extraction rate are improved, investment of the production line is greatly reduced, and original fragrance of the wheat is kept.

Description

technical field [0001] The invention provides a high-efficiency low-temperature crushing and crushing wheat flour milling process and device using 3 husks, 4 husks and 1 slag using a high-speed crushing and crushing machine, and a core grinding system using a water-cooled high-speed crushing and crushing mill. It is mainly used in wheat flour milling production line. Background technique [0002] The endosperm of the cleaned wheat is separated from the wheat husk and germ by grinding, impacting, sieving, flour cleaning and other equipment, and the endosperm is ground into powder to make various grades and uses of finished flour and by-products The whole process is called wheat flour milling process. The process flow of the whole grain wheat cleaning workshop is called the wheat room cleaning process, referred to as the wheat road; the process flow of the milling workshop is called the powder room process, referred to as the powder road. The existing powder road is divided ...

Problems solved by technology

However, after the authorization of the two patents, the inventor discovered during the implementation process that the patent "Efficiently Simplified Wheat Flouring Process and Equipment" replaced the prior art 2-bark tooth with "a pulverizer with the functions of impact crushing and extrusion shearing crushing". In the roller mill, because the endosperm grains adhered to the wheat bran are too large, large pieces of bran and endosperm are crushed together during processing, which cannot achieve the slagging effect expected by the design
