Description

The system for feeding of food waste

The present invention relates to a food waste processing system for producing food waste generated at home or a restaurant, such as livestock feed or agricultural compost, and more specifically, the imported food waste is sorted by a sorting mill, a dehydrator, and a fermentation dryer. After the grinding process, dehydration process and fermentation drying process are conducted efficiently, the fermented dry food feed is pulverized and molded into circular granules in the particle molding machine, and then microorganisms are coated on the feed particles in the microbial coating machine to obtain high quality. By producing fermented feed, food waste is produced as livestock feed, reducing waste of resources, preventing environmental pollution, and providing high-quality fermented feed to livestock farmers to promote nutrient intake and digestion. It relates to a waste feed system.

In general, most food wastes generated at home or in restaurants are mixed with various mixtures and contain a large amount of moisture. Therefore, the food wastes are easily decomposed when the temperature is high. Together, leachate is generated, causing serious environmental pollution that contaminates soil and groundwater.

If the food waste is disposed of as waste, it not only causes waste of resources but also costs and environmental pollution due to waste disposal, that is, soil pollution and water pollution due to leachate from food waste, and odor and Gases and pests cause various skin diseases and infectious diseases, and are becoming a major cause of environmental pollution.

Therefore, recently, in order to improve the problems of food waste generated in homes and restaurants, and to reduce environmental pollution and waste of resources, food wastes containing moisture are collected and collected separately from general garbage, and produced as food feed or agricultural compost. It is a trend to recycle.

In order to produce and recycle food waste as livestock feed or agricultural compost, various foreign substances and metals such as vinyls, chopsticks, and bottle caps mixed with food wastes are removed, and the food waste is crushed to an appropriate size. After dehydration to some extent by dehydration, the dehydrated food waste is sterilized while fermented and dried to produce livestock feed or agricultural compost.
