Fermentation process for producing compound microbial protein feed by utilizing agricultural and sideline dregs

Abstract

The invention relates to the technical field of biological engineering, in particular to a fermentation process for producing a compound microbial protein feed by utilizing agricultural and sideline dregs. The fermentation process comprises the following steps that 1, materials are put for mixing; 2, high-temperature sterilization treatment is performed; 3, fermentation treatment is performed, wherein the fermentation temperature is controlled to 30-37 DEG C in a continuous temperature control mode, air is supplied, stirring is performed, and aerobic fermentation is performed by fermenting special bacteria. The invention further relates to a fermentation device for producing the compound microbial protein feed by utilizing the agricultural and sideline dregs. The fermentation process is simple, the efficiency of treating the agricultural and sideline dregs is high, the cost is low, and the fermentation process is suitable for large-scale solid fermentation of agricultural and sideline dregs. By utilizing the fermentation device, heating can be rapid, the materials can be more evenly mixed without dead space, and meanwhile local microbe insufficiency can be avoided.

Description

technical field [0001] The invention relates to the technical field of bioengineering, in particular to a fermentation process and fermentation equipment for producing compound bacterial protein feed by using agricultural and sideline dregs. Background technique [0002] There are many types and large quantities of dregs unconventional feed resources in my country, but dregs cannot be directly used as feed in the breeding process because of their high water content, acid-base imbalance, anti-nutritional factors, and high crude fiber content. use. The use of fermentation technology can effectively degrade the anti-nutritional factors of agricultural and sideline dross resources, ferment and produce biological feed, improve the utilization rate of waste, and solve the environmental problems caused by the corruption and deterioration of traditional Chinese medicine factories and feed factories due to untimely removal and transportation. Pollution and economic loss issues. Howe...

Problems solved by technology

However, the current fermentation method has low treatment efficiency and high cost, and is not suitable for large-scale solid fermentation production; moreover, there are some problems in the use of existing fermentation equipment, such as uneven mixing of materials in the fermentation equipment, easy to produce dead ends, and some The material will adhere to the inner wall of the fermentation equipment, which will eventually affect the quality of the fermentation product, resulting in a low utilization rate of agricultural and sideline residues; the fermentation equipment will heat up slowly during the fermentation process, which will affect the fermentation time; the material needs to be supplied with gas during fermentation, and the existing The gas supply device is to realize the gas supply by setting the gas supply pipe in the fermentation equipment, and then discharge the waste gas through the waste gas port. The above gas supply method is likely to cause insufficient oxygen uptake by local microorganisms, affect the reproduction of microorganisms, and finally affect the quality of fermentation products; for the above problems, there are It is necessary to establish a fermentation process for producing bacterial protein feed using agricultural and sideline residues, and it is necessary to develop a fermentation equipment for producing bacterial protein feed using agricultural and sideline residues for this process
