METHOD FOR ACCELERATED COMPOSTING OF ORGANIC WASTE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC C05F17/00 B09B3/00 

FIELD: agriculture.

SUBSTANCE: method of accelerated composting of organic waste is characterized by the fact that it comprises the following steps: preliminary composting, main composting, ripening of granules; at the same time, at the stage of preliminary composting, organic raw materials (ORM) are placed in the sections to start composting, ensuring its aeration by supplying air from the bottom parts of the section for six days until the humidity of the ORM reaches 63-67%, on the seventh day, the ORM is transferred to the main composting stage into the trench loading zones by a loader or dump truck, where, using a single composter-granulator located on a self-propelled frame, ORM is mixed alternately in two concrete trenches parallel to each other and having one outer side and one common side, moving along the trenches along the rails located on the sides of the trenches, and between the trenches, the composter-granulator moves perpendicular to the trenches along the frame with the help of a moving part, with the help of the composter-granulator, within one trench, the ORM gradually moves to the unloading zone, from where the ORM is transported to the granule ripening section for the granule ripening stage, where, for up to twelve days, the granules are aerated without the impact of a composter-granulator. The device for implementing the method is characterized by the fact that it consists of two concrete trenches, a composter-granulator, an aeration system and a microclimate system, moreover, the concrete trenches are parallel to each other and have one outer side and one common side, on which rails are located for moving along the trenches self-propelled frame, on which there is a composter-granulator configured moving across the trenches with the help of a moving part mounted on wheels on the frame, having a hydraulic cylinder designed to transfer the composter-granulator from the working position to the non-working one, by turning about the axis located on one from the sides of the moving part, which is a rectangular frame, having a length half the length of the frame; in addition, the composter-granulator comprises a rotating shaft, on which brackets with curved knives are located throughout the entire circumference and entire length; whereas the aeration system is located in the bottom of each trench.

EFFECT: increased production productivity.
