Food waste is generally solid liquid mixed, with complex chemical composition, mainly including water, inorganic salt, starch, protein, cellulose, lipids and other organic substances, as well as a small amount of nutrients such as nitrogen, phosphorus, potassium and calcium. The composition of kitchen waste is relatively unstable, and is greatly affected by regional differences, folk customs and eating habits. But there are some similarities on the whole. In addition to rice noodles, oil, fruits and vegetables, meat, seafood shells, bones and other food ingredients, there are often disposable tableware, paper towels, plastic and other sundries. Food waste treatment equipment What is the development status of?

1. Various processing technologies.

Compared with other urban domestic waste, food waste contains a lot of starch, protein and other organic substances, which are rich in nutrition and less harmful ingredients. Among them, organic components have high biodegradation rate and great recycling value. Use the fruit and vegetable garbage processor to Food waste treatment It not only has the problems of thorough treatment, good safety and no secondary pollution, but also uses the life activities and metabolism of microorganisms to degrade the organic components in food waste. A treatment method for transforming food waste into simple inorganic substances, mainly including aerobic composting, anaerobic digestion, solid-state fermentation to prepare protein materials and aerobic digestion.

2. It can be treated innocuously.

Compared with other food waste treatment processes, the biochemical processor can realize fully mechanized operation, with high degree of automation and simple operation. The on-site aerobic degradation of food waste fully shortens the storage time of waste, avoids the possible secondary pollution of food waste during storage and transportation, and saves a lot of transportation costs. At the same time, after the equipment runs for a period of time, the remaining kitchen waste can be made into organic fertilizer by controlling the machine temperature. At the same time, the high temperature during composting also improves the removal efficiency of pathogenic bacteria, so as to realize the reduction and resource utilization of food waste treatment.

In the process of food waste degradation by food waste treatment equipment, the organic components are gradually degraded into small molecular organic acids at the initial stage of degradation. As the organic acid accumulates in the pile, the pH value will drop briefly. Organic acids are then consumed and utilized by microbial metabolic activities. In this process, a large amount of energy is released for the growth and reproduction of microorganisms. Organic acids are oxidized and decomposed, and pH begins to rise until the end of the degradation cycle.
