Description

Bacteria bag waste treatment system for the production of fermented forage grass

technical field

The invention relates to a bacteria bag waste treatment system, in particular to a bacteria bag waste treatment system for producing fermented forage grass.

Background technique

In the production process of fermented forage grass, the bacteria bag waste should first be crushed and screened, and then sent to the mixer. The inoculated base material is pressed into a column, and finally wrapped and sealed with a film for packaging. Bacteria bag waste is the main raw material for the production of fermented forage grass. The bacteria bag waste is mainly packaged in film or plastic bags. During the production process, the bacteria bag waste needs to be crushed first to form a powdery material, and then screened. When crushing, there will be a lot of discarded plastic fragments, and the crushing effect will also affect the quality of the fermented forage grass column. Therefore, it is necessary to obtain a powdery material with small particle size and less film plastic or grain husk. Because the powdery material contains debris such as plastic fragments, it also needs to be screened.
