Description
Technical field
The present invention relates to a kind of production system of feed, more particularly to a kind of production system of DDGS feeds, belong to DDGS
Feed production technology field.
Background technology
Alcohol Plant produces the raw materials such as alcohol generally use corn and carries out liquid state fermentation, and starch is converted to ethanol and titanium dioxide
Carbon, other nutritional ingredients such as protein, fat, fiber are stayed in mash.Simultaneously because the effect of microorganism, egg in mash
White matter, B family vitamin and amino acid content increased than corn, and contain the unknown somatomedin generated in fermentation,
It is good protein feed.
DDGS(Distillers Dried Grains with Solubles), be by cleaner liquid dry concentration after again with
Filter residue combination drying and the feed obtained.Because DDGS protein content is more than 26%, it has also become domestic and international Feed Manufacturing
The wide variety of a kind of novel protein feed raw material of enterprise, commonly used to Substitution for Soybean Meal, fish in livestock and poultry and aquatic product matched feed
Powder, adding proportion reach as high as 30%, and can be with Direct-fed ruminant.
Traditional DDGS feed production systems are:Alcohol Plant's mash that gives up is isolated into alcohol slag and clear liquid, alcohol slag is entered
Row drying.To improve yield, when alcohol slag is dried, it is in parallel using more pipe bundle driers, every pipe bundle drier
Alcohol slag is disposably dried to moisture content up to less than 12%, then dried alcohol slag carried out using the concentrate of clear liquid
Add slurry.Following weak point be present in such technique:(1) alcohol slag, can shape on surface after being oven-dried and being less than 12% to moisture content
Into a shell, now carry out plus slurry, concentrate are not easily penetrated into inside alcohol slag, are simply bonded in the surface of alcohol slag, make
Alcohol slag is easy to agglomerating caking, poor product quality.(2) disposable drying is carried out to alcohol slag in place, steam consumption is big, does
Dry efficiency is low, is unfavorable for the cascade utilization of energy.(3) in order to discharge humidity, the exhausting amount ratio of pipe bundle drier as quickly as possible
Larger, the aperture of fresh air air door is also bigger so that the exhaust temperature of pipe bundle drier is low, high containing air capacity, reduces tail gas
Quality, be unfavorable for tail gas carry out heat recovery.
The content of the invention
It is an object of the present invention to overcome problems of the prior art, there is provided a kind of production system of DDGS feeds,
