A heatless drying device 2 is movably installed on the left side of the microwave cracking device 1, a screw extrusion dehydrator 3 is movably installed on the left side of the heatless drying device 2, and an anaerobic digestion device 4 is movably installed on the left side of the screw extrusion dehydrator 3. The heatless drying device 2 and the microwave cracking device 1 are connected through a first conveying pipe 9. The heatless drying device 2 includes a heatless drying body 201, a feed hopper 202 and a sewage pipe 203. The heatless drying body 201 is movably installed on the left side of the microwave cracking device 1, the feed hopper 202 is fixedly installed on the top of the heatless drying body 201, and the sewage pipe 203 is fixedly installed on the bottom of the heatless drying body 201.

[0024] By adopting the above scheme: through the setting of the condensation system 6 and the filter 7, the gas generated by cracking can be effectively cooled and filtered, and the purpose of harmless emission can be achieved, thereby completing the complete treatment of food waste. Through the setting of the heatless drying device 2, it is convenient to add the composite dehydrating agent and conditioning agent specially used for heatless drying to the biogas residue after anaerobic digestion, so as to release the moisture in the microbial cells of the biogas residue, effectively improve the dehydration performance of the biogas residue, and make it easy to separate the moisture and solid particles in the biogas residue.

[0025] refer to Figure 1 , Figure 4 and Figure 5 The anaerobic digestion device 4 and the screw extrusion dehydrator 3 are connected through a feed pipe 10. The anaerobic digestion device 4 includes an anaerobic digestion reaction tank 401, a second feed pump 402, a feed port 403, a stirring motor 404, a stirring shaft 405 and a stirring paddle 406. The anaerobic digestion reaction tank 401 is movably installed on the left side of the screw extrusion dehydrator 3, the second feed pump 402 is fixedly installed on the left side of the anaerobic digestion reaction tank 401, the feed port 403 is opened on the top of the second feed pump 402, the stirring motor 404 is fixedly installed on the top of the anaerobic digestion reaction tank 401, the stirring shaft 405 is fixedly installed on the bottom of the stirring motor 404, and the stirring paddle 406 is fixedly installed on the surface of the stirring shaft 405.

[0026] The above scheme is adopted: through the setting of the anaerobic digestion device 4, the kitchen waste can be anaerobically fermented. Under anaerobic conditions, microorganisms can decompose the organic matter in the kitchen waste, produce biogas and organic fertilizer, thereby effectively reducing the volume and weight of the kitchen waste and reducing the load on the environment. At the same time, the use of biogas also reduces greenhouse gas emissions, which is conducive to mitigating climate change.

[0027] Working principle:

[0028] When in use, firstly, kitchen waste is put into the anaerobic digestion device 4 for anaerobic fermentation to ferment the kitchen waste into biogas residue. The biogas residue after anaerobic digestion is preliminarily dehydrated by the screw extrusion dehydrator 3 to reduce the moisture content therein. Then, the heatless drying device 2 separates the moisture and solid particles in the biogas residue after the preliminarily dehydration to further reduce the moisture content in the biogas residue. Then, the biogas residue with a lower moisture content is cracked and carbonized by the microwave cracking device 1. During the cracking process, toxic and harmful high-molecular organic substances undergo a series of reactions to decompose and escape their small molecular substances, and are fully burned in the combustion chamber and reused in the system. In addition, the heavy metal ions in the biogas residue are combined with the solidified carbon with stable chemical bonds. The heavy metal ions are transformed from the original extractable state to the stable state, which is difficult to separate from the carbon, so that they cannot be leached in the environment and will not cause secondary pollution. Finally, the gas generated by the cracking is cooled and filtered by the condensation system 6 and the filter 7, and the harmless gas is discharged into the natural environment through the vent pipe 8, thereby completing the treatment of kitchen waste.

[0029] In summary: this food waste fermentation device, through the coordinated use of a microwave cracking device 1 and an anaerobic digestion device 4, solves the problem that the treatment methods of sludge after anaerobic digestion of food waste in my country are mainly divided into three categories: incineration heat generation, aerobic composting, and feed. Among them, incineration heat generation is the most significant way to reduce the amount of sludge treatment methods, but the process will produce secondary pollution.
