Silage feed for ruminant farming is widely used. Corn stalks and pastures, as well as some specific plants, are the main source of raw materials for silage. The moisture content of silage feed before fermentation is controlled between 60-75%, which is an ideal moisture content. In this state of water content, it is beneficial to the fermentation of microorganisms and the maintenance of nutrients in silage.

  The corn stalks used as raw materials for silage have different moisture content in raw materials at different harvest times, different regions, different years and specific natural rainfall conditions. For industrial production and utilization of silage feed, to overcome the changes in the moisture content of raw materials brought about by these changes, it is unscientific to adjust the moisture content of raw materials solely by drying and adding other materials with low moisture content, which is also difficult to achieve. Drying is subject to site and climatic reasons, and the addition of other materials with low moisture content is also subject to raw material sources.

  It is a more scientific and easy-to-use method to use mechanical methods to control the moisture content of silage raw materials. The screw press, as a physical mechanical way of pressing and dewatering, has the advantages of low operating cost, large output, reliable operation, low maintenance cost, continuous operation, and low labor intensity. Moreover, the moisture control can be adjusted by mechanical parts to control the moisture content of the silage raw materials within an ideal range.

  At present, the screw press can achieve a throughput of 40m³ / h, and the moisture content can be controlled between 60-75.
