Simple preparation method of bacillus bacteria powder

Abstract

The invention discloses a simple preparation method of bacillus bacteria powder. The method comprises the steps of 1) mixing fermented bacillus fermentation liquor and a bacteria liquid adsorbent according to a weight ratio of 1.0 : 1.0-1.5, stirring uniformly; 2) spreading the uniformly-mixed mixture of the fermentation liquor and the bacteria liquid adsorbent with a thickness of 2 cm-3 cm, putting in a ventilated position for naturally drying; and finishing the preparation of the bacteria powder when the water content is reduced to 20% or lower. Microbial ecological agents are prepared directly by employing the bacteria liquid adsorbent to absorb active bacteria and metabolism products thereof in the fermentation liquor and drying. The method is simple in process, has low technical difficulty, omits a thallus separating procedure after the fermentation is finished, and makes the most of beneficial metabolites of probiotics in the fermentation liquor.

Description

technical field [0001] The invention belongs to the technical field of microecological preparations and relates to a simple preparation method for feeding bacillus powder. Background technique [0002] Microecological preparations refer to live bacteria mainly used for animals that contain only live bacteria or bacterial cells and their metabolites, which are isolated from animals inside and outside the body and beneficial to animals according to the theory of microecology. preparation. [0003] The processing methods currently used for probiotics preparations mainly include spray drying, vacuum freeze drying and microcapsule coating. Most of the existing micro-ecological products in the market adopt the spray drying method. The advantage of the drying method is that the processing capacity is large, the obtained microcapsule powder has good fluidity, and the processing process is easy to control. The vacuum freeze-drying method is also one of the most widely used methods ...

Problems solved by technology

The vacuum freeze-drying method is also one of the most widely used methods in the application of microbial products. Through the vacuum freeze-drying method, micro-ecological products with a high rate of viable bacteria can also be obtained, but the vacuum freeze-drying method has the following problems: high application cost ( 5-8 times that of spray drying), time cost is relatively high (48h / batch), equipment loss is relatively rapid, and the prepared products are assembled together, which needs further crushing, powder making, and poor fluidity

Although these three processing methods are widely used, they all require the addition of expensive drying protective agents or carriers, professional drying equipment, and the production process is relatively complicated, which must be operated by professional personnel.
