Abstract
The invention discloses a starch processing technology, and relates to the technical field of starch processing. The starch processing technology is characterized by comprising the following steps: corn storing and purifying, corn soaking, corn crushing, finely grinding, fiber separating, washing and drying, and starch separating, washing and drying, wherein the corn storing and purifying step comprises the specific steps of weighing corn raw materials, adding the corn raw materials into a raw materials bin, purifying the corn raw materials through vibration-screening, stone-clearing, magnetic separation and other procedures, metering, and then putting the purified corn raw materials into a purified corn bin; the fiber separating, washing and drying step comprises the specific steps of pumping starch paste obtained after the finely grinding step and the washing water generated in the fiber washing step into a first-stage pressure curved screen to be subjected to screening after the starch paste enters a fiber washing slot. According to the invention, the process is reasonable, the speed is high, the efficiency is high, and the prepared starch is fine, small in impurity amount and good in quality.
Description
Technical field:
The present invention relates to starch processing technique field, particularly relate to a kind of complete processing of starch.
Background technology:
Corn originates from South America, then by Europe, Africa imports Asia into, corn in China through there being more than 470 year cultivation history.Corn claims again chinese sorghum, and one of Ta Shi world Three major grain crops is again important feedstuff raw material, and because it is dry ground crop, per unit area yield is high, yield potential is large, therefore in agriculture production, accounts for consequence.Corn wet milling processing is to adopt the method for physics that each main component of corn kernel is separated to the process of obtaining corresponding product.Can obtain five kinds of main components by this course of processing: starch, plumule, soluble proteins, skin slag (fiber), seitan (protein).Because of the ratio maximum of starch contained therein in corn, general contents on dry basis is in 70% left and right, thus claim that traditionally starch is major product, and all the other products are byproduct.From corn kernel, produce starch, the master operation that overall technical process should comprise: the cleaning impurity elimination of corn, soaking corn in sulfurous acid solution, the broken corn kernel soaking, separated plumule from broken corn kernel, fine grinding cornmeal mush, the screening of skin slag and washing, isolated protein from the mixing suspension of starch and protein, washing starch is therefrom isolated soluble substance, the mechanical dehydration of starch, starch dry.Existing making W-Gum technique, the W-Gum of producing meticulous not, has more fiber impurity and cause the starch quality of plant not high, and production rate is slow, and efficiency is low.
Summary of the invention:
Technical problem to be solved by this invention is to provide that a kind of starch of producing is meticulous, impurity is few, the complete processing of the measured starch of matter.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A complete processing for starch, is characterized in that: comprise the following steps corn storage and purification, corn soaking, the fragmentation of corn, fine grinding, the separation of fiber, washing and dry, the separation of starch, washing and dry;
Described corn is stored and is purified as raw material corn adds raw material cabin after weighing, and removes, removes the operations such as stone, magnetic separation and purify, removing maize storage house after metering through vibratory screening apparatus;
Separation, the washing of described fiber and being dried as the slurry after fine grinding enters after fibre washing bath, reinstates and is pumped into first step pressure curved sieve at this and the washing water one of washing later, sieves.
Described corn soaking adverse current in the sulfurous acid aqueous solution is carried out.
Described fine grinding is the grout after secondary spinning liquid is isolated plumule, and by pressure curved sieve, screen underflow is coarse starch milk, and after starch milk and fine grinding, isolated thick farinaceous size enters starch separation circuit after converging; Screen overflow enters impact grinding, carries out fine grinding.
The invention has the beneficial effects as follows: process of the present invention is reasonable, and speed is fast, and efficiency is high, the starch produced is meticulous, impurity is few, quality good.
Embodiment:
Further illustrate the present invention below by embodiment.
A complete processing for starch, comprises the following steps, corn storage and purification, corn soaking, the fragmentation of corn, fine grinding, the separation of fiber, washing and dry, the separation of starch, washing and dry;
Corn is stored and is purified as raw material corn adds raw material cabin after weighing, and removes, removes the operations such as stone, magnetic separation and purify, removing maize storage house after metering through vibratory screening apparatus;
Separation, the washing of fiber and being dried as the slurry after fine grinding enters after fibre washing bath, reinstates and is pumped into first step pressure curved sieve at this and the washing water one of washing later, sieves.
Corn soaking adverse current in the sulfurous acid aqueous solution is carried out.
Fine grinding is the grout after secondary spinning liquid is isolated plumule, and by pressure curved sieve, screen underflow is coarse starch milk, and after starch milk and fine grinding, isolated thick farinaceous size enters starch separation circuit after converging; Screen overflow enters impact grinding, carries out fine grinding.
The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
