Abstract

This invention relates to a two-sieve-in-series dehydration method for corn embryo during the production of cornstarch milk, characterizing: before the separated water-bearing embryo enters the squeezing dehydrator, it sequentially passes through the series two stages gravity dehydration sieves for two times of water removing, and then is sent to the squeezing dehydrator for dehydration. By applying this two-sieve-in-series dehydration method, it can decrease the water content of the embryo squeezed out from the squeezing dehydrator by 5%, and the efficiency of the squeezing dehydrator can be doubled at the same time.

Description

The two sieve of maize germ tandem dehydration method in the W-Gum milk production

Technical field:

The invention belongs to the corn deep processing field, specifically germ separation dehydration method in the W-Gum milk production.

Background technology:

China is large agricultural country, and agricultural resource is abundant, and the ultimate production of main farm produce, commodity amount are all at the forefront in the world, so deep processing of farm products is big rising industry.

Corn is one of main food crop of human plantation, accounts for 1/4th of world food overall crop yield.Corn also is the main food crop kind of China, and ultimate production is only second to paddy and wheat, occupies the second place of the world.The anxious especially economic field leaved for development of its comprehensive process.

Corn has ripe soon, high yield, plantation area are wide, the starch-containing amount height of seed, by product is wide in variety, values is high, be easy to transport and storage, can annual processing etc. advantage.Therefore, countries in the world are all attached great importance to corn deep processing, and the corn of western countries more than 50% is used for production comprehensive process product, and are individual surplus kind has 4000.

The more direct effect of corn deep processing is the development of pulling agricultural industry chain, and corn resources development and use potentiality are very big, and its deep processing project is various, and is of many uses, and market capacity is big, the industry chain length, and development prospect is limitless.

W-Gum is after certain processing technique is handled, can be widely used in food, papermaking, weaving, medicine, chemical industry and related industries thereof, as beverage industries, confection industry, milk industry, meat processing, seasonings, nutrition pot foods, functional health-care food, zymin, various additives, Brewing industry and building coating, Di Kuang, petrochemical complex etc., purposes is very extensive, and its market outlook are very wide.

For a long time, the glycogen of China is based on sucrose, and excessive sucrose intake can cause the generation of the multiple disease of people, and high fructose syrup is main glycogen in American-European countries, in recent years along with the change of Chinese's level of consumption, consumption idea, healthy, health-related food fast development, high added value glycogen place of sucrose such as high fructose syrup enlarge rapidly in the market of China.

Dian Fentang is not only the functional product that improves human health, and the particular requirement and the people that have also adapted to foodstuffs industry processing variant production simultaneously pursue healthy requirement.Therefore develop the industry policy that glucose industry meets China fully, help improving and promoting the development of China's food-processing industry state of the art.

Corn starch milk is a primary raw material of producing Dian Fentang.

In the W-Gum milk production, germ separation is gone out, and it is dehydrated as far as possible, be used to process feed, corn wet goods product is one of link of corn deep processing comprehensive utilization.

Existing technology is after corn steep liquor is sent into secondary degerming mill and the washing of secondary germ separation, to send into gravity dehydration screening water, enters then and extracts the machine dehydration.Because the plumule water content that enters before the machine of extracting is bigger, after extracting machine, the water content of plumule is about 60%, and water content is higher, has influenced the efficient of the machine of extracting, and also is unfavorable for the reprocessing of next step operation to plumule simultaneously.

Summary of the invention:

In order to reduce the water content enter plumule before the machine of extracting to greatest extent, improve the production capacity of the machine of extracting, the inventor improves former plumule dewatering.

The technical scheme that the inventor proposes is the two sieve of a maize germ tandem dehydration method, technical scheme of the present invention is the gravity dehydration sieve front in former technical process, increase gravity dehydration sieve of series connection again, make isolated moisture plumule before entering the machine of extracting, successively by placed in-line two-stage gravity dehydration sieve, carry out twice minute water, send into then and extract the machine dehydration.Suitably reduce the rotating speed of the machine of extracting simultaneously, prolong plumule and enter the time of the machine of extracting, thereby reach the purpose that reduces the plumule water content.

Use two sieve tandem dehydration method of the present invention, can make, the efficient of the machine of extracting is doubled from extracting the plumule water content decline 5% that machine is extruded.

Embodiment:

To enter germ cyclone separation and the plumule after washing through the secondary degerming mill in the corn starch milk course of processing, send into one-level gravity dehydration sieve earlier and carry out branch water, and then the plumule that water content is higher, send into secondary gravity dehydration sieve again and continue to divide water, plumule water content after the secondary series connection divides water obviously reduces, and then send into and extract machine dehydration, will extract speed drop to 8 ~ 10 rev/min of machine simultaneously, to improve dewatering efficiency.

Claims

1. the two sieve of maize germ tandem dehydration methods in the W-Gum milk production, it is characterized in that and to enter germ cyclone separation and the plumule after washing through the secondary degerming mill in the corn starch milk course of processing, send into one-level gravity dehydration sieve earlier and carry out branch water, and then the plumule that water content is higher, send into secondary gravity dehydration sieve again and continue to divide water, plumule water content after the secondary series connection divides water obviously reduces, and then send into and extract the machine dehydration, to extract speed drop to 8 ~ 10 rev/min of machine simultaneously, to improve dewatering efficiency.
