Food waste is an important component of organic matter in urban solidified waste, which mainly includes protein, lipid, starch, inorganic salt and other perishable substances. The basic characteristics of kitchen waste components can be mainly reflected in the following aspects: First, high water content, which will have a certain impact on the collection and treatment of kitchen waste. Second, it is easy to rot. Generally, the organic content of kitchen waste is relatively high, which is easy to breed bacteria. Third, the reuse value is relatively high. Therefore, the disposal of food waste cannot be simply mixed with ordinary domestic waste for incineration, and must comply with the treatment principles of "recycling", "harmless" and "reduction".

At present, the traditional treatment of domestic food waste is mainly landfill and incineration, which can only meet the "reduction" principle of the "three modernizations" principle, but in the long run, it is not consistent with the sustainable development of society and the environment. On this basis, a relatively mature and scientific comprehensive treatment technology for food waste has been formed in recent years. At present, there are two restaurant kitchen processing technologies on the market. First, large Food waste treatment The centralized treatment process of "mechanical pretreatment+anaerobic digestion" commonly adopted by manufacturers; The second is the distributed treatment process route of "pretreatment+high-temperature aerobic fermentation", which is mostly used for small or mobile waste treatment points. These two processes complement each other in the current kitchen waste treatment mode.

Local market at present Kitchen waste treatment equipment There are mainly two types: elimination type and resource type.

The technical principle of the kitchen waste treatment equipment of the energy dissipating restaurant: the organic waste is decomposed through aerobic fermentation with the help of microbial strains, so that it can be treated locally at the source. In the process of degradation, the cloud intelligent management platform can be used to adjust the temperature, humidity, oxygen content and other data of the degradation room, improve the processing speed, shorten the processing cycle, and achieve the purpose of mechanized production. It can partially reduce the amount of garbage and reduce environmental pollution during collection and transportation. Less sewage is generated during operation, which can effectively avoid noise and secondary pollution during garbage removal and reduce transportation costs.

Although the kitchen waste treatment equipment of resource-based local restaurants can recycle the end products, the production cost of input is high, and the environmental requirements of output materials are difficult to meet, so the market is controversial.

At present, the extinctive type is on the spot Food waste treatment equipment The application effect is good, which can ensure the unity of economic benefits and environmental benefits.
