Technique for processing millet with remained germ

Abstract

The invention provides technology for processing millet rice with remained germ. In the technology, unpolished rice which is screened through husked rice separation with husking yield and serviceability rate of rice germ more than or equal to 97 percent, moisture content of between 12.5 and 14 weight percent is adopted as a raw material for processing the rice with remained germ; four ranges of rice milling machines are arranged, wherein two parallel machines are arranged in each range; four-placer four-iron combined rollers are adopted in first milling and second milling; an additional air jetting device is arranged in the range of third milling to form a wind packing auger, so that air-jet capacity can reach 120 to 170m / h; the rice milling machine of the fourth range is connected with a set of negative pressure air nets, with air quantity of between 15,000 and 18,000 cubic meters / hour; and the millet rice with remained germ with complete germ and germ content of between 80 and 85 percent can be finally obtained through rice grading screen and color selection. The technology has the advantages of scientific and reasonable design and mature implementing technology; and by the technology, the millet rice with remained germ with complete germ, high germ content and rich nutrient ingredients can be produced, thereby realizing large-scale industrial production of the millet rice with remained germ for the first time.

Description

technical field [0001] The invention relates to the field of grain processing, in particular to the processing technology of millet with germ. Background technique [0002] There are roughly two traditional techniques for millet processing: one is the "workshop" technique of "one breaking and one polishing". Its characteristic is that the output is small, and it is difficult to exceed 30T / d. requirements, and the rice germ is broken and becomes feed together with the bran. The other is a multi-machine light milling process, which is the embodiment of contemporary rice milling theory, using a horizontal rice mill. The design of the multi-machine light milling process, especially the large-tonnage 150T / d wool millet processing production line is at an immature stage in my country. The main parameters and equipment are designed according to rice processing, so it cannot meet the requirements of millet processing, let alone realize it. Industrial processing of germ rice. [0...

Problems solved by technology

The design of the multi-machine light milling process, especially the large-tonnage 150T / d wool millet processing production line is at an immature stage in my country. The main parameters and equipment are designed according to rice processing, so it cannot meet the requirements of millet processing, let alone realize it. Industrial Processing of Germ Rice

[0003] The configuration of the existing process technology, equipment structure and process parameters, etc., either make the millet processed with high precision, so that all or most of the embryos are milled off to become bran, resulting in the loss of nutrients in the embryo; or the precision is too low, so that Too much seed coat is retained, making too much crude fiber, which is difficult for people to digest after eating
