The organic fertilizer double screw turning machine needs to prepare raw materials when making fertilizer, and some auxiliary materials must be added. The main raw materials and various auxiliary materials that are roughly stacked together in proportion can be mixed evenly by relying on the compost turner to achieve the effect of granulation by the granulator. When the pile turner is operating, the raw material pellets are fully contacted and mixed with the air, and a lot of fresh air can be cultivated in the pile, which helps aerobic microorganisms to actively generate fermentation heat and the pile temperature rises. When the temperature is high, the supply of fresh air It can lower the temperature of the pile. Forming a high-temperature exchange shape, various beneficial microorganisms develop and multiply in the temperature range to which they are adapted.

The organic fertilizer double-helix turning machine can process the materials into small clumps, making the viscous and dense pile of raw materials loose and elastic, forming appropriate porosity. The raw materials of the compost turner have suitable moisture content for fermentation, and the moisture content of the finished compound fertilizer should be below 20%. During fermentation, biochemical reactions will generate new water, and the consumption of raw materials by microorganisms will also cause the water to dissolve the carrier and be freed. Therefore, as the moisture is reduced in time during the fertilizer making process, in addition to evaporation caused by heat conduction, the turning of raw materials by the compost turner will cause forced water vapor distribution.
