Efficient aerobic fermentation and drying composting device

Abstract

The invention discloses a high-efficiency aerobic fermentation and drying composting device, and relates to good fermentation and composting equipment, in particular to aerobic composting equipment. Comprising a cuboid box body, and a feeding screw conveyor, an air energy air heater, a discharging conveyor and an exhaust pipe which are connected with the cuboid box body, the cuboid box body is divided into a heat energy chamber and a composting chamber through a partition plate. Large-area air energy hot air heating and movable stirring are combined, a negative pressure type suction mode is adopted for deodorization, efficient and uniform heating is achieved, gaps are easy to form, water evaporation is rapid, aerobic bacteria are high in activity and rapid in breeding, so that the fermentation period is short, meanwhile, pathogenic microorganisms are effectively inactivated, and peculiar smell can be prevented from being generated.

Description

technical field [0001] The invention relates to a composting device, in particular to an aerobic composting and drying device. Background technique [0002] With the development of urbanization, the scale of hotels, hotels and canteens is expanding, and the amount of kitchen waste and kitchen waste is increasing. Most of the organic solid slag is incinerated or landfilled, and a small amount of organic solid slag is produced by anaerobic biogas or organic composting. However, the current organic composting technology has the following defects: composting covers a large area, the composting temperature is unstable, and the composting oxygen supply is insufficient. The evaporation rate of water is slow, so the composting fermentation period is long. At the same time, the pathogenic microorganisms cannot be effectively inactivated, and the generation of odors cannot be prevented. Due to the above defects, the organic solid residue composting method is difficult to promote. The...
