Embodiment 1

[0030] An embodiment of the present invention provides a method for pretreatment of straw biological feed raw materials, comprising the following steps:

[0031] S1. Preparation

[0032] First, soak the straw in clean water at 28-32°C for 2 hours, then wash the straw with clean water at 18-22°C for 4 times, dry the remaining water in the straw with a hot air blower after cleaning, and then use a magnetic separator to clean the straw. The straw is magnetically separated, and then sterilized and disinfected with ultraviolet germicidal lamps for 12 minutes. After soaking, elutriation can remove dust, soil and other impurities on the straw, and magnetic separation can remove metal impurities;

[0033] S2. Smash

[0034] First cut and crush the straw with a pulverizer, and then further grind and crush the crushed straw with a ball mill. The grinding time is 18 minutes. After crushing and grinding, the particle size of the straw can be reduced and the surface area can be increased;...

Embodiment 2

[0048] An embodiment of the present invention provides a method for pretreatment of straw biological feed raw materials, comprising the following steps:

[0049] S1. Preparation

[0050] First, soak the straw in clean water at 28-32°C for 3 hours, then wash the straw with clean water at 18-22°C for 5 times. The straw is magnetically separated, and then the straw is sterilized and disinfected with an ultraviolet germicidal lamp for 15 minutes. After soaking, elutriation can remove dust, soil and other impurities on the straw, and magnetic separation can remove metal impurities;

[0051] S2. Smash

[0052] First cut and crush the straw with a pulverizer, and then further grind and crush the crushed straw with a ball mill. The grinding time is 24 minutes. After crushing and grinding, the particle size of the straw can be reduced and the surface area can be increased;

[0053] S3. Cooking

[0054]Put the crushed straw into the pressure tank, and add pure water into the pressure...

Abstract

The present invention provides a pretreatment method of straw biological feed raw materials and relates to the technical field of biological feeds. The pretreatment method of the straw biological feedraw materials comprises the following steps: S1, preparing; S2, crushing; S3, cooking; S4, filtering; and S5, fermenting. Firstly, straws are physically crushed and ground, surface areas of the straws are increased, the straws are cooked under high-temperature and high-pressure conditions to separate cellulose, hemicellulose and lignin from one another, at the same time, the cellulose, hemicellulose and lignin in the straws can be crushed by an ultrasonic crusher, then after cooking is finished, a pressure tank is instantaneously filled with air to further separate the cellulose, hemicellulose and lignin in the straws, so that the cellulose, hemicellulose and lignin in the straws can be separated more thoroughly after multiple times of treatment, furthermore, contact areas between a composite microbial agent and each component in the straws are larger during fermentation, so that the straws can be decomposed more quickly and better, and the pretreatment method of the straw biologicalfeed raw materials is worthy of vigorous popularization.

Description

technical field [0001] The invention relates to the technical field of biological feed, in particular to a pretreatment method for straw biological feed raw materials. Background technique [0002] Bio-feed refers to the general term for feed products developed through fermentation engineering, enzyme engineering, protein engineering, genetic engineering and other bio-engineering technologies using feed raw materials and additives permitted by relevant national laws and regulations. There are dozens of bio-feed products developed worldwide. Varieties have become a larger industry, mainly including feed enzyme preparations, feed amino acids and vitamins, prebiotics (directly fed to microorganisms), feed oligosaccharides, plant natural extracts, bioactive oligopeptides, feed biological Pigment, new feed protein, biological drug feed additive, etc. [0003] Straw biological feed raw materials are the most common biological feed raw materials on the market at present. The organ...
