Embodiment 1

[0027] The probiotics used in this example include Saccharomyces cerevisiae, lactic acid bacteria, Bacillus subtilis, acetic acid bacteria, bifidobacteria, and actinomycetes; the probiotic seed liquid is obtained after the probiotics are fermented in the basal medium for 20 hours fermentation broth. Basal medium components include 0.5% peptone, 0.5% sodium chloride, and 1% sodium phosphate. Invertases include glucoamylase, cellulase, mesophilic amylase, acid protease, and β-glucanase.

[0028] Step 1) Concentration: use rotary heating and evaporation to concentrate the cassava distiller's grains to a Baume degree of 40°Bé to obtain cassava distiller's grains concentrate.

[0029] Step 2) Ripening: Take 80 parts of the cassava distiller's grain concentrate obtained in step 1) according to the parts by weight, add 20 parts of probiotic seed liquid and 5 parts of invertase, stir evenly, and ferment under anaerobic conditions at 37°C for 25 hours to obtain mature cassava Distill...

Embodiment 2

[0035] The probiotics used in this example include Saccharomyces cerevisiae, lactic acid bacteria, Bacillus subtilis, and bifidobacteria; the probiotic seed liquid is the fermentation liquid obtained after the probiotics were fermented in the basal medium for 24 hours. Basal medium components include 1% peptone, 1% sodium chloride, and 0.5% sodium phosphate. Invertases are glucoamylase, cellulase, acid protease, β-glucanase.

[0036]Step 1) Concentration: use rotary heating and evaporation to concentrate the cassava distiller's grains to a Baume degree of 30°Bé to obtain a cassava distiller's grains concentrate.

[0037] Step 2) Ripening: Take 90 parts of cassava distiller's grain concentrate obtained in step 1) in parts by weight, add 15 parts of probiotic seed liquid and 2 parts of invertase, stir evenly, and ferment under anaerobic conditions at 30°C for 15 hours to obtain mature cassava Distiller's grains. The content of beneficial bacteria in the aged distiller's grains...

Embodiment 3

[0043] The probiotics used in this example include Saccharomyces cerevisiae and Bifidobacterium; the probiotic seed liquid is the fermentation liquid obtained after the probiotics were fermented in the basal medium for 16 hours. Basal medium components include 0.8% peptone, 0.5% sodium chloride, and 1.5% sodium phosphate. Invertases are glucoamylase, acid protease, and β-glucanase.

[0044] Step 1) Concentration: use rotary heating and evaporation to concentrate the cassava distiller's grains to a Baume degree of 40°Bé to obtain cassava distiller's grains concentrate.

[0045] Step 2) Ripening: Take 85 parts of the cassava distiller's grain concentrate obtained in step 1) according to the parts by weight, add 15 parts of probiotic seed liquid and 5 parts of invertase, stir evenly, and ferment under anaerobic conditions at 40°C for 10 hours to obtain mature cassava Distiller's grains. The content of beneficial bacteria in the aged distiller's grains can reach 2-5g / Kg.

Abstract

The invention relates to a method for preparing a high-protein forage by utilizing waste cassava vinasse. The method comprises the steps: 1) utilizing rotation heating evaporation to concentrate a cassava vinasse liquid; 2) adding a probiotics seed liquid and invertase into the cassava vinasse concentrated liquid, uniformly stirring and fermenting; 3) putting the cassava vinasse slurry into a diaphragm type filter press to perform positive-pressure water draining, extruding water draining, residual liquid evacuating and air back flushing, and collecting filtrate; 4) putting vinasse filter cakes in a drying apparatus to perform high-temperature ventilation drying; 5) stirring the filtrate, corn flour, wheat bran fine powder, peanut bran and soybean meal to mix uniformly; and 6) grinding dry filter cakes into granular vinasse, uniformly mixing granular vinasse and dry regulators, preparing into granules, and drying to obtain the high-protein forage. The method is low in production cost and helps to reduce environmental pollution and change waste into valuables, and the prepared forage product is high in nutrition value, abundant in beneficial bacteria, free of hormones and free of antibiotics.

Description

technical field [0001] The invention relates to the technical field of cassava feed production, in particular to a method for preparing high-protein feed using waste cassava distiller's grains. Background technique [0002] The waste liquid treatment of cassava alcohol production is related to the environmental benefits of the industry and the recovery of industrial profits, and has always been a research hotspot of domestic scholars. For example, Zhou Haifeng and others analyzed the characteristics of each section of the fermented alcohol industry, and proposed a new circular economic model based on the "3R" principle of circular economy, including the recovery and utilization of biogas produced by anaerobic fermentation of distiller's waste liquid, and the utilization of fermented biogas residues. Production of ecological compound fertilizers, collection and utilization of carbon dioxide and fusel oil by-products produced by alcohol fermentation, heat pump recycling of pro...
