The fermentation drying device is characterized by comprising a fermentation tank, a stirring shaft, a temperature sensor, a heating element and an automatic door closing device, wherein the stirring shaft is arranged in the fermentation tank, a feeding port and a bacteria inlet are formed in the top surface of the fermentation tank, the heating element is arranged at the bottom of the fermentation tank, one side wall of the fermentation tank is provided with an exhaust port and the temperature sensor, a discharging port is formed in the side surface of the lower part of the fermentation tank, the feeding port corresponds to a kitchen waste outlet in the lower end of a sorting device, the bacteria inlet is provided with a sealing door, the discharging port is provided with a discharging door, the feeding port is provided with the automatic door closing device, the stirring shaft is provided with stirring blades, two ends of the stirring shaft are respectively and fixedly connected with the fermentation tank through a bearing and a bearing seat, and the stirring shaft is driven by a stirring motor. The fermentation drying device has the advantages of simple structure, high treatment speed, uniform fermentation, high heating speed, automatic oxygen filling, automatic feeding, automatic discharging, environmental protection without pollution and the like.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a fermentation and drying device for treating kitchen waste. Background technique [0002] With the development of society and economy, the acceleration of urbanization, and the improvement of living standards, the amount of kitchen waste is increasing day by day, which has exceeded the self-purification ability of the earth and has become a worldwide public hazard: 1. Disease spread and gene mutation. Due to the similar gene sequences of vertebrates, eating each other can easily cause the spread of zoonotic diseases such as mad cow disease, foot-and-mouth disease, avian influenza, and SARS, as well as gene mutations and offspring developmental deformities caused by homologous gene pollution, which can easily induce cancer; 2. Resources waste. The annual output of kitchen waste in my country is about 60 million tons, which is equivalent to the annual p...

Problems solved by technology

[0004] In the prior art, there is a device that uses a biological fermentation tank to treat garbage. It is equipped with a stirring shaft in the fermentation tank. The upper end of the fermentation tank is provided with a feed port, and the lower side is provided with a raw material discharge port. The bottom of the fermentation tank is along the direction of the axis of the stirring shaft. There is an oxygenation gap, the air enters from the raw material discharge port of the mixing tank, and is discharged from the feeding port. The stirring shaft is provided with spiral blades to facilitate the mixing of garbage. The disadvantages are: unreasonable structure, cumbersome production, and The oxygenation gap is set at the bottom of the mixing tank, which is easy to block the material and cause insufficient oxygenation fermentation. The second is that the temperature of the mixing tank is not easy to control, and the fermentation time is not fixed, resulting in insufficient fermentation and extremely slow processing efficiency.

[0005] After retrieval, CN2730508A discloses a patent for the invention of a garbage sterilization and fermentation tre
