Description
Technical field
The present invention relates to the production system of a kind of feedstuff, particularly to the production system of a kind of DDGS feedstuff, belong to DDGS
Feed Production Technology field.
Background technology
Alcohol Plant produces ethanol and generally uses the raw materials such as Semen Maydis to carry out liquid fermentation, and starch is converted to ethanol and titanium dioxide
Carbon, other nutritional labelings such as protein, fat, fiber etc. are all stayed in mash.Simultaneously because the effect of microorganism, egg in mash
White matter, vitamin B group and amino acid content all increased than Semen Maydis, and containing the unknown somatomedin generated in fermentation,
It it is good albumen feedstuff.
DDGS(Distillers Dried Grains with Solubles), be cleaner liquid is dried after concentration again with
Filtering residue combination drying and the feedstuff that obtains.Owing to the protein content of DDGS is more than 26%, it has also become Feed Manufacturing both at home and abroad
The wide variety of a kind of novel protein feed raw material of enterprise, is commonly used to Substitution for Soybean Meal, fish in poultry and aquatic product matched feedstuff
Powder, adding proportion reaches as high as 30%, and can be with Direct-fed ruminant.
Traditional DDGS feed production system is: the mash that Alcohol Plant given up isolates ethanol slag and clear liquid, enters ethanol slag
Row is dried.For improving yield, when ethanol slag is dried, multiple stage pipe bundle drier is used to be in parallel, every pipe bundle drier
Disposably ethanol slag is dried and reach less than 12% to moisture content, then use the concentrated solution of clear liquid that dried ethanol slag is carried out
Add slurry.There is following weak point in such technique: (1) ethanol slag be oven-dried to moisture content less than 12% after, can shape on surface
Becoming a shell, now carry out adding slurry, concentrated solution is not easily penetrated into inside ethanol slag, is simply bonded in the surface of ethanol slag, makes
Ethanol slag is easy to agglomerating caking, poor product quality.(2) disposably drying ethanol slag and put in place, steam consumption is big, dry
Dry efficiency is low, is unfavorable for the cascade utilization of energy.(3) in order to discharge humidity as quickly as possible, the convulsion amount ratio of pipe bundle drier
Relatively big, the aperture of new wind air door is the biggest so that the exhaust temperature of pipe bundle drier is low, high containing air capacity, reduces tail gas
Quality, be unfavorable for tail gas is carried out heat recovery.
Summary of the invention
It is an object of the invention to, overcome problems of the prior art, it is provided that the production system of a kind of DDGS feedstuff,
Energy consumption is low, drying efficiency height and good product quality.
