Production method of feed from wheat distillers' grains by non-drying method and feed

Abstract

The invention discloses a production method of feed from wheat distillers' grains by a non-drying method and the feed, and relates to the field of feed processing. The method is characterized in thatby a microbial fermentation technique, high-moisture distillers' grains and a large amount of another by-product bran in production of wheat alcohol are mixed, and a bacillus subtilis KG109 and bacillus subtilis R-02 combined fermentation method is used for producing fermented wheat distillers' grain feed with the moisture content of about 35%. Compared with the prior art, the product needs not drying and can be stored for a long term before being unpacked, so energy consumption of drying is saved, high expense for drying is avoided, and the defects of protein denaturalization and reduction ofutilization ratio caused by high-temperature drying are overcome. Owing to the effects of microbial protease, protein in partial distillers' grains is degraded into small peptides with biological activity, thereby achieving an immunological enhancement effect on fed animals.

Description

technical field [0001] The invention relates to the field of feed processing, in particular to a production method of wheat distiller's grains used as feed without drying and the feed. Background technique [0002] The production process of producing alcohol with wheat as raw material, such as figure 1 As shown, it can be seen from the production process that after the distiller's grains are centrifuged, the grains are dried to obtain wheat DDG, which becomes a traditional protein feed material. Because, only after drying the distiller's grains with a water content of about 85% to a water content of about 12%, can long-term storage and long-distance transportation be realized. However, the energy cost of drying is relatively high, about 700 yuan / ton. And in the drying process, it is easy to cause protein denaturation, and the utilization rate of feed nutrients is reduced. Therefore, it is urgent to develop a new process to reduce the processing cost when wheat distiller's ...

But the energy cost of drying is relatively high, about 700 yuan / ton

And in the drying process, it is easy to cause protein denaturation, and the utilization rate of feed nutrients is reduced. Therefore, it is urgent to develop a new process to reduce the processing cost when wheat distiller's grains are recycled, and to develop a high utilization rate and beneficial Feed developed from wheat distiller's grains with high content of ingredients
