Abstract

The invention discloses a technological process and a production method of corn starch. Fiber feed, protein powder, commercial corn starch and other products can be obtained by carrying out treatments such as cleaning impurities, soaking, washing corns, degerming, fine grinding, separating the fiber, separating the protein, washing the starch on corn raw materials. The process is simple and clear; the raw materials are completely converted into the required products without a complex manual operation, thereby realizing a complete utilization of all values of the raw materials; and thus the method has strong practicability.

Description

A kind of making method of W-Gum

Technical field

The invention belongs to the W-Gum technical field, relate in particular to a kind of making method of W-Gum.

Background technology

The leaching process of starch is the chief component separating process of corn, and the separation of each integral part of corn grain has two kinds of dry method and wet methods, and lock out operation main be to grind; Therefore; The branch of dry grinding and wet-milling is arranged, and wet-milling is the general technology of current corn starch industry, is mainly the corn process fragmentation behind the process dipping, takes off embryo, correct grinding and screening; To tell plumule, fibrous residue, the process of the rough milk of starch of system.After starch wearable riddler preface proposed, the gained milk of starch still was a coarse starch milk, still contains a large amount of insoluble proteins and soluble substance; And the concentration of powder slurry is also rarer, need make with extra care and concentrate, for processing and deep processing at last provides purified smart milk of starch; The purified method is to utilize the spinning principle, and coarse starch milk is separated, and tells the water that gently contains insoluble protein mutually; Both seitan water; Heavy phase is a milk of starch, utilizes pure water to wash away soluble substance remaining in the milk of starch again, has both obtained smart milk of starch.On the one hand; Adopt the preparation method of the W-Gum of prior art to utilize the method for spinning to carry out spissated technology deficiency so that the insoluble protein in the seitan water is fully separated once more to seitan water, separation efficiency is low, and causes the productivity of gluten protein powder not high; On the other hand; After the direct cyclically utilizing of process water is in technique for soaking corn and the milk of starch washing process, the remarkable variation of washing effect of the immersion effect of corn and milk of starch, and influence the quality of smart milk of starch.

Summary of the invention

The present invention is directed to the deficiency that exists in the existing W-Gum manufacture craft; As adopt the preparation method of the W-Gum of prior art to utilize the method for spinning to carry out spissated technology deficiency once more so that the insoluble protein in the seitan water is fully separated to seitan water; Separation efficiency is low, and causes the productivity of gluten protein powder not high; After the direct cyclically utilizing of process water is in technique for soaking corn and the milk of starch washing process; The remarkable variation of washing effect of the immersion effect of corn and milk of starch; And influence quality of smart milk of starch etc., a kind of technical process and making method of W-Gum proposed.

The embodiment of the invention is achieved in that a kind of making method of W-Gum, and this making method may further comprise the steps:

The first step, clear assorted; Maize raw material is put into carries out assortedly clearly in the special-purpose shaker screen, filter out impurity such as broken corn and handstone;

Second step, immersion; The full corn grain that will pass through mixes clearly obtains is put into water pot and is soaked for some time;

The 3rd step, corn washing; Soaked corn is through stirring the impurity and the dust on flush away corn surface in water pot;

The 4th goes on foot, takes off embryo; The corn that washing is good carries out one-level and takes off embryo, and the plumule that breaks away from fully presses water through germ separation, germ washing, plumule and tube bank is dry, obtains plumule; The corn that does not break away from fully carries out secondary and takes off embryo and germ separation;

The 5th step, fine grinding; The corn of sloughing plumule is put into shredder carry out fine grinding;

The 6th step, fiber separation; Raw material after the fine grinding carries out fiber separation, and the fiber that obtains presses water, mixes, restrains dry and pulverizing with the broken corn and the impurity that filter out through fiber, obtains fiber feedstuff;

The 7th step, albumen sepn; Material after the fiber separation carries out albumen sepn, and the protein that separation is obtained carries out that flotation concentrates, box press filtration, air stream drying, tube bank is dry and pulverize, and obtains protein powder;

The 8th step, starch washing; Leftover materials are carried out the starch washing, through milk of starch dehydration and air stream drying, obtain commodity corn starch then.

The technical process of the W-Gum that the embodiment of the invention provides and making method;, immersion, corn washing clearly assorted, take off processing such as embryo, fine grinding, fiber separation, albumen sepn, starch washing, can obtain products such as fiber feedstuff, protein powder and commodity corn starch through maize raw material is carried out.Present method flow process is simple and clear, need not the complex manual operation, and the product that becomes people to need feedstock conversion has fully utilized the institute of raw material valuable fully, is the very strong method of a kind of practicality.
