preparation example Construction

[0022] The invention provides a method for preparing fermented cold granulated feed, comprising the following steps: after pulverizing and mixing feed raw materials and microbial concentrated enzyme protein, putting them into a cold granulation device for fermentation and granulation; adjusting and matching the cold granulation device The ring die and the compression ratio make the temperature of the material in the cold granulation device rise during granulation, and when the temperature rises to 60°C to 65°C, it is cooled to obtain fermented cold granulation feed.

[0023] The feed raw materials and microbial concentrated enzyme protein used in the present invention are granulated through a cold granulation device after being pulverized. The present invention has no special limitation on the specific manner of pulverization, and all methods that can realize the pulverization effect of feed raw materials and microbial concentrated enzyme protein are within the protection scope...

Embodiment 1

[0050] 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. In the said microbial inoculum, by weight ratio, it contains 10% bean curd powder and 90% diatomaceous earth, and the contents of Bacillus subtilis and Bacillus coagulans contained therein are respectively 1×10 8 CFU / g.

[0051] The feed 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:

[0052] 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 material in the feed fermentation mixer is 50%; add 7.5kg of microbial agents into the above feed fermentation mixer, the inverter The f...

[0056] 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. In the first microbial inoculant, by weight ratio, containing 15% bean curd powder, 85% diatomaceous earth, wherein the total content of Bacillus subtilis, Bacillus coagulans and yeast is 1 × 10 9 CFU / g.

[0057]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. In the second microbial inoculum, by weight ratio, containing 15% bean curd powder, 85% diatomaceous earth, wherein the total content of Bacillus subtilis, Bacillus coagulans and saccharomyces is 1 × 10 9 CFU / g.

Abstract

The invention relates to the technical field of feed processing and preparation and discloses a preparation method of a fermented cold-pelletized feed. The preparation method comprises the following steps: pulverizing and mixing feed raw materials and microbe concentrate enzyme protein, feeding the mixture into a cold pelletization device, and performing fermentation and pelletization; adjusting a circular mould and compression ratio matched with the cold pelletization device so as to ensure that the temperature of the mixture in the cold pelletization device increases during pelletization; and cooling the mixture when the temperature increases to 60-65 DEG C, thereby obtaining the fermented cold-pelletized feed. According to the preparation method of the fermented cold-pelletized feed, the fermentation and cold pelletization device is utilized, and the feed raw materials and the microbe concentrate enzyme protein are organically combined during pelletization so as to be subjected to rapid fermentation and enzymolysis, so that a predigesting feed is obtained. A heating device is not needed, vapor hardening and tempering pelletization is not needed, mutual friction heating between a machine and materials is directly utilized, and fermentation conditions are provided so as to rapidly realize microbe propagation and convert a macromolecular substance into a micromolecular substance, so that a predigestion function of the feed is realized.

Description

technical field [0001] The invention relates to the technical field of feed processing and application, in particular to a method for preparing 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 the raw materials, the most important thing is to realize the functionalization and ecologicalization of the feed during the feed processing process, which is of great significance to improving animal welfare and creating ecological cycle agriculture. [0003] At present, the high-temperature thermal granulation process is usually used in the existing feed processing and granulation proce...
