Problems solved by technology

[0002] Food waste has a high water content, accounting for about 75% to 85% of the total waste, which is not conducive to traditional methods such as landfill, incineration, composting, and pyrolysis, and contains a large number of harmful bacteria and pathogenic bacteria. Traditional treatment methods cannot completely inactivate them. In view of the shortcomings of traditional treatment methods, a device and method for high-temperature inactivation of food waste pathogenic bacteria is now provided.

Embodiment Construction

[0014] An application example of the device and method will be described with reference to FIG. 1 . Xining Qinghai Jieshen Environmental Energy Industry Co., Ltd. established a 60 ton / day harmful bacteria inactivation drying sterilizer based on this device and method.

[0015] Through compression, crushing, and dehydration, the particle size of the kitchen waste particles is kept at 0.1-10mm, and the humidity is less than 60%; then the processed kitchen waste is sent into the feeding port, and then goes through the preheating and rising room, the isothermal drying room, High-temperature drying room and ultraviolet sterilization room are used for inactivating high-temperature ultraviolet harmful bacteria. After entering the preheating chamber, the temperature of the food waste is raised to 120°C at 7°C per minute, and then kept for 15 minutes; in the isothermal drying chamber, the temperature is kept at 120°C, and the food waste is kept for 30 minutes under the stirring of the ...

Abstract

The invention relates to a high temperature-UV inactivation device for the harmful bacteria of kitchen garbage and a method thereof. The invention can further carry out UV disinfection even after the constant temperature and high temperature heat treatment of the kitchen garbage in a sealed spiral dryer, so as to inactivate the pathogen, conditioned pathogen and other harmful microorganisms in the kitchen garbage, and safe and sanitary renewable raw materials or feeds can be generated after the inactivation process. The inactivation device has compact structure, high sterilization rate and simple operation, so the invention is a very effective inactivation method of the harmful microorganisms of kitchen garbage.

Description

technical field [0001] The invention relates to a processing technology for kitchen waste, in particular to a high temperature inactivation device and method for pathogenic bacteria of the kitchen waste. Background technique [0002] Food waste has a high water content, accounting for 75% to 85% of the total waste, which is not conducive to traditional methods such as landfill, incineration, composting, and pyrolysis, and contains a large number of harmful bacteria and pathogenic bacteria. The traditional treatment method cannot make it completely inactivated. Aiming at the shortcomings of the traditional treatment method, a device and method for high temperature inactivation of pathogenic bacteria of kitchen waste are provided. SUMMARY OF THE INVENTION [0003] The high temperature inactivation device for pathogenic bacteria of kitchen waste includes a feeding chamber, a preheating and warming chamber, an isothermal drying chamber, a high temperature drying chamber, an ul...
