Process for preparing liquid fermentation feed from distiller's grains

Abstract

The present invention relates to a process for preparing a liquid fermentation feed from distiller's grains. According to the process, raw materials are mixed according to a certain ratio, wherein the raw materials comprise, by weight, 40-60% of corn, 20-40% of soybean meal, 10-20% of sodium bicarbonate, 5-10% of minerals, 2-4% of trace elements, and 1% of probiotics; the raw material are crushed, and are subjected to mixing and bagging according to the ratio; distiller's grain wet residue and a distiller's grain concentrated slurry are mixed according to a mass ratio of 1:1-1.5, and then are subjected to sealing storage, wherein a storage life is more than 6 months; and the obtained two materials are mixed according to a mass ratio of 1:3-5, water is added to adjust the pH value of the obtained material C to achieve the pH value of 6-7, and placement fermentation is performed for 4-8 h to obtain the fermentation feed.

Description

technical field

[0001] The invention relates to a production method of feed, in particular to a process for preparing liquid fermented feed from distiller's grains. Background technique

[0002] In the microbial fermentation liquid in the alcohol fermentation industry, after the alcohol is extracted, the remaining liquid is the fermentation raffinate. The fermentation residue has a high content of organic substances and cannot be discharged. Now it is mostly dried and used as feed raw materials. Alcoholic fermentation raffinate has a low solid content, mostly 10-12%, and cannot directly enter the drying process. It needs to be separated and concentrated to make the solid content reach about 35%, and then enter the drying process.

[0003] There are two kinds of concentrated substances, one is the filter residue part after being extruded by the plate and frame, which is in a solid state, called distiller's grains wet residue, which is characterized by relatively high protein...

Embodiment 1

[0025] Embodiment 1: see figure 1 ,

[0026] (1) Production of material A (dry state)

[0027] The production of material A (dry state) is carried out in the wet state feed processing plant. 50.5% of corn, 24.0% of soybean meal, 14.5% of baking soda, 7.2% of minerals, 2.8% of trace elements and 1.0% of compound probiotics are crushed, mixed in proportion and packed into bags.

[0028] (2) Production of material B (wet state)

[0029] The production of material B (wet state) is also carried out in the wet state feed processing plant. Mix the wet dregs of the wine tank and the concentrated distiller's grains in a ratio of 1:1 and put them in a closed container (sealed plastic bag or sealed barrel). The storage period is more than 6 months, which can fully meet the storage requirements in production. time. If the material B is not used up at one time, the air in the packaging bag needs to be drained, and the airtight storage should be carried out to prevent corruption.

[0034] (1) Production of material A (dry state)

[0035] The production of material A (dry state) is carried out in the wet state feed processing plant. 48.5% of corn, 25.0% of soybean meal, 14.5% of baking soda, 8.2% of minerals, 2.8% of trace elements, and 1.0% of compound probiotics are crushed, mixed in proportion and packed into bags.

[0036] (2) Production of material B (wet state)

[0037] The production of material B (wet state) is also carried out in the wet state feed processing plant. Mix the wet dregs of the wine tank and the concentrated distiller's grains in a ratio of 1:1.2 and put them in a closed container (sealed plastic bag or sealed bucket). The storage period is more than 6 months, which can fully meet the storage requirements in production. time. If the material B is not used up at one time, the air in the packaging bag needs to be drained, and the airtight storage should be carried out to prevent corruption.

[0043] The production of material A (dry state) is carried out in the wet state feed processing plant. 48.5% of corn, 26.0% of soybean meal, 14.5% of baking soda, 7.2% of minerals, 2.8% of trace elements, and 1.0% of compound probiotics are crushed, mixed in proportion and packed into bags.

[0044] (2) Production of material B (wet state)

[0045] The production of material B (wet state) is also carried out in the wet state feed processing plant. Mix the wet dregs of the wine tank and the concentrated distiller's grains at a ratio of 1:1.5 and put them in a closed container (sealed plastic bag or sealed bucket). The storage period is more than 6 months, which can fully meet the storage requirements in production. time. If the material B is not used up at one time, the air in the packaging bag needs to be drained, and the airtight storage should be carried out to prevent corruption.
