Feed preparation device based on solid state fermentation

Abstract

The invention provides a feed preparation device based on solid state fermentation. The feed preparation device comprises a feeding device, a strain culture device and a fermentation tank The feedingdevice is connected with the fermentation tank, and a pre-crushing mechanism is mounted in the feeding device; the strain culture device comprises a constant-temperature water bath and a culture dish;the culture dish is connected with the fermentation tank through a closable culture medium spraying pipe; a heating block, a temperature detection device and a humidity detection device are mounted on the inner wall of the fermentation tank, and a stirring device is arranged in the fermentation tank; the pre-crushing mechanism comprises a crushing part and a sieve plate. Technological conditionssuch as strain culture temperature, culture time, material feeding, fermentation temperature and humidity can be controlled through modular setting, automation of the fermentation process is realized,various technical requirements of an automatic fermentation process are met, a suitable product is provided, and convenience is brought to next-step crushing, granulation and filling. According to the invention, the artificial participation degree in the feed preparation process can be effectively reduced, the labor intensity and technical requirements of operators are reduced, and the device issuitable for large-scale feed production.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a feed preparation device based on solid-state fermentation. Background technique [0002] With the large-scale development of the breeding industry, the demand for functional feeds to solve animal disease resistance and nutritional problems is increasing. The preparation process of feed or feed additives based on solid-state fermentation of activated strains has become an important technical means for functional feed production. After fermentation, the protein in the raw material can be efficiently degraded, and the digestion inhibitors such as antigenic protein and oligosaccharides can be effectively removed. Beneficial for intestinal health and nutrient absorption in animals. [0003] Due to different fermentation processes, the preparation process needs to go through multiple processes such as strain cultivation and activation, raw material crushing, mixed fermentation, and agi...

AI Technical Summary

Problems solved by technology

In the prior art, the functions of each reaction vessel are single, and the materials cannot be automatically transferred to the next process. For example, the fermentation kettle only has a fermentation function, and cannot realize the cultivation and activation process of bacterial strains and automatic feeding, nor can it realize drying and activation. All require professional and technical personnel to manually operate each step and master the process conditions. However, the fermentation and curing process takes a long time and requires long-term manual intervention. The production labor intensity and technical requirements are high, which is not conducive to large-scale application.
