Abstract
The present invention is method of separating dietary fiber from side product of grain processing. The separation process includes the following steps: superfine crushing rice bran, corn coat, wheat bran or bean residue to obtain material of 50 micron below fineness; and air grading the material in an air separating machine to obtain dietary fiber as main product and protein containing fine powder. The separation process is mechanical, and the protein grain, cellulose, semi-cellulose and pectin in the mixture have different specific weight and are separated in the high speed rotation process to obtain dietary fiber product with high cellulose content and fine powder with high protein content. The separation process has no chemical material residue and is simple and practical.
Description
Technical field: the present invention relates to a kind of method that dietary fiber in the byproduct of grain processing is separated.
Background technology: contain rich dietary fiber (content is 60～80%) in the byproduct rice bran after paddy, wheat, corn and soybean processing (byproduct of paddy rice milling), maize peel (byproduct of corn deep processing), wheat bran (byproduct of wheat flour milling), the dregs of beans (byproduct of soybean deep processing).It has a wide range of applications in some fields, has remarkable social benefit and economic benefit.It can promote human intestines and stomach's wriggling with being health food, and the acceleration bodies endotoxin excretes.Can also remove interior free yl, have antioxidation.Also to preventing and treating coronary heart disease, obesity, prevention hypertension, diabetes and anti-human primary gastrointestinal cancers etc. have good action for it.In addition, also can add in the food such as bread, candy, can make its structure keep soft, promote flavour of food products, prolong storage life, help to improve the food processing quality; Also can add in the meat products, keep meat products moisture, reduce its heat to utilize.But owing to lack separation method preferably, the above-mentioned several byproducts that contain dietary fiber can only be with being to make the raw material of feed product or directly with being feed.Its value and price level all lower (per ton do not wait) at 100～500 yuan.How to make in above several byproduct that content is abundant, the higher dietary fiber of nutritive value therefrom separates to the mankind and benefits? how to significantly improve its value and price level? this is the present invention method problem to be solved just.
Summary of the invention: purpose of the present invention just provides a kind of method that dietary fiber in the byproduct of grain processing is separated.The technical scheme of this method is as follows: a kind of edible dietary fiber separation method, it is realized by following step: (one) grinds arbitrary product in rice bran, maize peel, wheat bran or the dregs of beans through the ultra micron pulverizer, obtain the following material of fineness 50 μ m, (2) this material is entered carry out air classification in the air classifier, obtain major product dietary fiber and proteinaceous fine powder after the separation respectively.Method of the present invention is to use the mechanical crushing principle, the materials such as cellulose, hemicellulose and pectin grain that are bonded on the protein in rice bran, maize peel, wheat bran, the arbitrary particle of dregs of beans are rushed open, form independent cellulose, hemicellulose, pectin hybrid particles and protein particulate, different according to the protein particulate in the mixture and cellulose, hemicellulose, pectin hybrid particles proportion then, in the high speed rotary course, utilize the size of centrifugal force, isolate the higher fine powder of content of cellulose rich dietary fiber and protein content.Arbitrary products such as rice bran, maize peel, wheat bran, dregs of beans are after the inventive method is separated, and the major product of generation is a dietary fiber, and yield is 80～85%.Secondly for protein content is 8～10%, yield is at 15～20% fine powder.By the present invention method the value and the price level of rice bran, maize peel, wheat bran, dregs of beans etc. all are significantly improved.We's pure physical refining processes owned by France does not use chemical reagent in the technical process, it is remaining therefore not have chemical raw material.It has simple and practical advantage.
The specific embodiment one: the step of the edible dietary fiber separation method of present embodiment is: at first, rice bran sent in the ultra micron pulverizer grind, obtaining fineness is the following materials of 50 μ m, then, the material of gained is blown into carries out classification in the air classifier, can obtain content of cellulose at 25～30% dietary fiber and protein content at 8～10% fine powder, wherein the fineness of dietary fiber is 15～50 μ m, the fineness of fine powder is 5～15 μ m.CWM-80 type and HTC-132 type equipment that employed ultra micron pulverizer and grader select for use Zhejiang Province Fengli smash equipment Co., Ltd to make respectively.
The specific embodiment two: the step of the edible dietary fiber separation method of present embodiment is: at first, maize peel sent in the ultra micron pulverizer grind, obtaining fineness is the following materials of 50 μ m, then, the material of gained is blown into carries out classification in the air classifier, can obtain content of cellulose at 25～30% dietary fiber and protein content at 8～10% fine powder, wherein the fineness of dietary fiber is 15～50 μ m, the fineness of fine powder is 5～15 μ m.
The specific embodiment three: the step of the edible dietary fiber separation method of present embodiment is: at first, wheat bran sent in the ultra micron pulverizer grind, obtaining fineness is the following materials of 50 μ m, then, the material of gained is blown into carries out classification in the air classifier, can obtain content of cellulose at 25～30% dietary fiber and protein content at 8～10% fine powder, wherein the fineness of dietary fiber is 15～50 μ m, the fineness of fine powder is 5～15 μ m.
The specific embodiment four: the step of the edible dietary fiber separation method of present embodiment is: at first, dregs of beans sent in the ultra micron pulverizer grind, obtaining fineness is the following materials of 50 μ m, then, the material of gained is blown into carries out classification in the air classifier, can obtain content of cellulose at 25～30% dietary fiber and protein content at 8～10% fine powder, wherein the fineness of dietary fiber is 15～50 μ m, the fineness of fine powder is 5～15 μ m.
Claims (1)
1, a kind of edible dietary fiber separation method, it is characterized in that it realizes by following step: (one) grinds rice bran, maize peel, wheat bran or dregs of beans through the ultra micron pulverizer, obtain the following material of fineness 50 μ m, (2) this material is entered carry out air classification in the air classifier, obtain major product dietary fiber and proteinaceous fine powder after the separation respectively.
