Environment-friendly production method of food waste as feed

Abstract

The environment-friendly production method of turning food waste into feed includes the following steps: (1) automatic sorting machine for mechanically removing impurities; (2) pulverizing and pulping machine for pulverizing and pulping the sorted food waste; (3) pulping The material is sent to the pretreatment solid-liquid separation device for separation of solid and liquid; (4) The solid matter of the separated kitchen waste enters the steam-intensified turning and throwing dehydration device for dehydration treatment; (5) The drum-type aerobic fermentation device (6) Crush and remove soft impurities to make feed additives and store in ice. In the present invention, the solid matter after solid-liquid separation is rich in organic matter and trace elements such as nitrogen, phosphorus, potassium, calcium, zinc, iron, manganese, and various activated organisms such as auxin, vitamins, organic elements, amino acids, etc., and then dehydrated, good Oxygen fermentation, crushing out impurities, and then fermenting again to form bacterial agents, which can be made into fermented feed additives, can fully and reasonably recycle food waste, and reduce the occupation and pollution of environmental resources.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, and in particular relates to an environment-friendly production method of turning kitchen garbage into feed. Background technique [0002] The main method of processing kitchen waste in the prior art is: one, directly get rid of by sewer pipe after pulverizing. However, this method is only applicable to the situation where the amount of kitchen waste is small, and there are disadvantages, such as easy to cause blockage of drainage pipes, increase the burden of urban sewage discharge, and cause secondary pollution. Second, direct landfill. Although this method is simple to operate and convenient to handle, it does not conform to the development concept of energy saving, environmental protection and recycling, and it is easy to cause waste of available resources. After the solid-liquid separation, the food waste needs to be dehydrated again. The turner is a kind of equipment for dehydra...

Problems solved by technology

Although this method is simple to operate and convenient to handle, it does not conform to the development concept of energy saving, environmental protection and recycling, and it is easy to cause waste of available resources.

After the solid-liquid separation, the food waste needs to be dehydrated again. The turning machine is a kind of equipment for dehydrating food waste. When the existing turning machine is working, because the food waste is in the state of normal temperature and pressure The dehydration effect is not good, and the solid food waste coming out of the outlet of the turner still contains a certain amount of water (the water content is still high), and it takes more energy and time to dry (dry) in the follow-up processing, and it is not conducive to making microbial feed after fermentation
