Problems solved by technology

Cassava distiller's grains are different from corn grains and rice grains in that they have deep color, high viscosity, and many fibers, and it is difficult to separate solids and liquids in the early stage. Therefore, the preparation of DDGS from potato distillers grains by means of concentration and drying will cost a lot due to equipment investment and drying concentration. Operating costs are so high that they are not economically viable
The third is to inoculate microorganisms to prepare fermented feed. Previous studies generally inoculate single strains such as lactic acid bacteria or yeast for fermentation to prepare lactic acid feed or single-cell protein feed. The feed obtained in this way can be stored for several months, prolonging the storage period or Improve its protein content, but the crude fiber content of distiller's grains is high, which limits the range of utilization of distiller's grains as feed, especially in non-ruminant farms.

Embodiment 1

[0037] Mix fresh cassava distiller's grains, bran and soybean meal by weight 5:3:2, and add 1.5% (NH4 ) 2 SO 4 , and 0.2% KH 2 PO 4 Prepare the distiller's grain medium, mix the prepared Trichoderma korningii suspension, Trichoderma viride spore suspension, yeast seed liquid, and lactic acid bacteria seed liquid in a volume ratio of 1:1:1:1, and add to the above distiller's grains In the culture medium, add 20ml for every 100 grams of distiller's grains medium, put the above inoculated medium into the fermentation tank, first open it at 25-28°C for 48 hours, then compact it, cover it with a plastic film, and coat it with a layer of 10cm For thick yellow mud, it can be fermented anaerobically for 10 days and dried at 50-55°C. It was determined that the protein content of the product increased by 32.8%, the cellulose content decreased by 7.6%, and the number of lactic acid bacteria was 2.9×10 8 cells / mL, the number of yeasts was 2.7×10 7 individual / mL.

Embodiment 2

[0039] Mix fresh cassava distiller's grains, bran and soybean meal by weight 5:3:2, and add 1.0% (NH 4 ) 2 SO 4 , and 0.4% KH 2 PO 4 Prepare distiller's grain medium, mix the prepared Trichoderma corning suspension, Trichoderma viride suspension, yeast seed liquid, and lactic acid bacteria seed liquid in a volume ratio of 1:1.2:0.5:0.5 and add them to the above medium , add 30ml per 100g of distiller's grains medium, put the above inoculated medium into the fermentation tank, first open it at 25-28°C for 72h, then compact it, cover it with a plastic film, and coat a layer of 8cm thick yellow Mud, anaerobic fermentation for 15 days, then dried at 50-55°C. It was determined that the protein content of the product increased by 33.4%, the cellulose content decreased by 6.7%, and the number of lactic acid bacteria was 3.7×10 8 cells / mL, the number of yeasts was 3.4×10 7 individual / mL.

Embodiment 3

[0041] Mix fresh cassava distiller's grains, bran and soybean meal in a weight ratio of 5:3:2, and add 1.2% of the total weight of fresh cassava distiller's grains, bran and soybean meal (NH 4 ) 2 SO 4 , and 0.3% KH 2 PO 4 Prepare distiller's grain medium, mix the prepared Trichoderma corning suspension, Trichoderma viride suspension, yeast seed liquid, and lactic acid bacteria seed liquid in a volume ratio of 1:2:0.8:0.8 and add them to the above medium , add 20ml per 100g of distiller’s grains medium, put the above-mentioned inoculated medium into the fermentation tank, first open it at 25-28°C for 26 hours, then compact it, cover it with a plastic film, and coat a layer of 5cm thick yellow Mud, anaerobic fermentation for 20 days, then dried at 50-55°C. It was determined that the protein content of the product increased by 31.9%, the cellulose content decreased by 8.2%, and the number of lactic acid bacteria was 2.3×10 8 cells / mL, the number of yeasts is 2.5×10 7 indiv...

Abstract

The invention relates to a method for producing a biologic feed from cassava lees, which comprises the following steps: preparing a lees culture medium; adding a mixture of a Trichoderma koningii suspension, a Trichoderma viride cladosporium suspension, a lactic acid bacterium seed liquid and a microzyme seed liquid to the lees culture medium for anaerobic culture and fermentation; and finally drying to obtain the biologic feed. The method has the advantages of low energy consumption, low cost, short production cycle and high production efficiency, realizes the recycling of resources and reduces the emission of pollutants. Besides, the invention shows that cassava lees can be used as the material for manufacturing a fermented feed and can improve the nutrition of the base material, a biologic feed which is rich in yeast, lactic acid bacteria and organic acid can be obtained, and the biologic feed can be used as the coarse feed for breeding cows and the like on an animal farm.

Description

Technical field: [0001] The invention relates to a method for producing microbial feed, in particular to a method for producing microbial feed by using cassava distiller's grains, a by-product of brewing alcohol in a brewery. Background technique: [0002] With the increasing scale of ethanol production in the world, people are facing another problem: how to efficiently utilize alcohol waste residue and waste liquid to maximize the profit of the alcohol industry, reduce waste emissions, reduce environmental pollution, and achieve energy saving, emission reduction, The dual purpose of comprehensive utilization. Alcohol waste liquid is the main by-product of the winery, its volume is about 10 times the alcohol production. All countries in the world are trying to solve the problem of distiller's grain utilization. Among them, the protein content of cassava distiller's grains is equivalent to that of barley, corn, and wheat distiller's grains, and the cellulose, total sugar an...
