Problems solved by technology

[0003] At present, in the existing feed processing and pelleting process in the industry, only feed raw materials are pelleted, and pre-digestion is not realized at the same time as feed pelleting, so it is difficult to improve the quality of feed in the process of feed processing and pelleting
Usually, the processing and granulation of feed is to use high-temperature hot granulation process to achieve rapid molding of feed. The high-temperature granulation process increases the loss of nutrients in the feed, especially for microorganisms and protein active substances that are unstable in temperature, and Great impact on feed quality, difficult to achieve environmentally friendly feed

Embodiment 1

[0049] Bacillus subtilis and Bacillus coagulans were multiplied and cultured at a ratio of 1:1. Add bean curd powder and diatomaceous earth to the cultured liquid bacteria, and dry at 35°C for 50 minutes at a low temperature to prepare a microbial bacterial agent. The microbial inoculum contains 10% soybean hull powder and 90% diatomaceous earth by weight ratio, and the total content of Bacillus subtilis and Bacillus coagulans contained therein is 1*10 8 CFU / g.

[0050] The feed raw material is fermented in a feed fermentation mixer by using a microbial agent to prepare microbial concentrated enzyme protein. The specific process is as follows:

[0051] Put 1000kg of soybean meal into the feed fermentation mixer that has been started, add 700kg of filtered water and stir for 3 minutes, so that the moisture content of the feed raw materials in the feed fermentation mixer is 50%; add 7.5kg of microbial agents into the above feed fermentation mixer. The frequency is 50HZ, the r...

Embodiment 2

[0055] Bacillus subtilis, Bacillus coagulans and yeast were multiplied and cultured at a ratio of 1:1:1. Add bean curd powder and diatomaceous earth to the cultured liquid bacteria, and dry at 37° C. for 45 minutes at a low temperature to prepare the first microbial agent. The first microbial agent contains 15% bean curd powder and 85% diatomaceous earth by weight ratio, and the total content of Bacillus subtilis, Bacillus coagulans and yeast contained therein is 1*10 9 CFU / g.

[0056]Bacillus subtilis and Bacillus coagulans were multiplied and cultured at a ratio of 1:3:1. Soybean skin powder and diatomaceous earth were added to the cultured liquid bacteria and dried at a low temperature of 37° C. for 45 minutes to prepare the second microbial bacterial agent. The second microbial inoculant contains 15% bean curd powder and 85% diatomaceous earth by weight ratio, and the total content of Bacillus subtilis, Bacillus coagulans and yeast contained therein is 1*10 9 CFU / g.

Embodiment 3

[0062] Soybean skin powder and diatomaceous earth were added to the bacterial solution containing Bacillus subtilis and dried at a low temperature of 40° C. for 50 minutes to prepare the first microbial bacterial agent. The first microbial agent contains 10% bean curd powder and 90% diatomaceous earth by weight ratio, wherein the total content of Bacillus subtilis is 1*10 8 CFU / g.

[0063] Add soybean hull powder and diatomaceous earth to the bacterial solution containing Bacillus coagulans, and dry at 40° C. for 50 minutes at low temperature to prepare the second microbial bacterial agent. The second microbial agent contains 10% bean curd powder and 90% diatomaceous earth by weight ratio, and the total content of Bacillus coagulans contained therein is 1*10 8 CFU / g.

[0064] The feed raw material is fermented in a feed fermentation mixer by using a microbial agent to prepare microbial concentrated enzyme protein. The specific process is as follows:

Abstract

The invention relates to the technical field of feed processing and preparation and discloses microorganism fermentation type cold granulation feed. The microorganism fermentation type cold granulation feed is prepared from, by weight, 50-70 parts of maize, 10-30 parts of bean pulp, 0.1-5 parts of compound premix additive and 5-15 parts of microorganism concentrated enzyme protein. The fermentation and cold granulation includes grinding and mixing the raw materials, putting the mixed ground raw materials into a cold granulation device, adjusting a circular mould and a compression ratio of the cold granulation device, enabling the raw materials to increase in temperature during granulation, and cooling when the temperature rises to 60-65 DEG C so as to obtain the microorganism fermentation type cold granulation feed. The microorganism fermentation type cold granulation feed has the advantages that the cold granulation device is used for preparing the feed, the raw materials and the microorganism concentrated enzyme protein are combined organically during granulation, and heat generated by mutual friction between the circular mould and the materials is used for providing fermentation conditions directly, so that microorganism multiplication, turning macromolecular substances into micromolecular substances and a feed predigestion function are achieved.

Description

technical field [0001] The invention relates to the technical field of feed processing and application, in particular to a microbial fermented cold-granulated feed. Background technique [0002] Feed processing refers to the feed production and processing activities applicable to pastures and farmers raising livestock, poultry, pets, and aquatic products. At present, both food safety issues and animal health issues are inseparable from feed processing technology, and are receiving more and more attention. To ensure food safety and animal health, in addition to the cleanliness of raw materials, the most important thing is to realize the pre-digestion and ecologicalization of feed during feed processing, which is of great significance to improving animal welfare and creating ecological cycle agriculture. [0003] At present, in the existing feed processing and pelleting process in the industry, only feed raw materials are pelleted, and pre-digestion is not realized at the sam...
