Catering waste is mainly composed of leftover food and other waste food. If it is directly discarded or treated as general municipal waste, it will not only pollute the environment and increase the amount of municipal waste treatment, but also cause waste of these waste food. In recent years, catering waste has been a major problem for some catering companies. The food waste dryer equipment developed by Zhengzhou Jiutian Drying Equipment Co., Ltd. has solved the problem of catering waste recycling and reuse.

The food waste dryer system uses materials to be crushed first to facilitate subsequent dehydration. The dehydrated materials are dried after dehydration, which reduces the drying energy consumption, and inactivates harmful microorganisms in the materials during the high-temperature drying process, which does not need to be established separately. The sterilization process simplifies the process of material processing and saves the energy required for individual sterilization. After drying and sterilization, the material is made into pellet feed, which facilitates the packaging, storage, transportation and use of feed products, and can be used during processing. According to the nature of the materials and the nutritional requirements of the feed, appropriate feed additives are added to adjust the feed to meet the nutritional requirements, which is conducive to the scientific rearing of the livestock being fed.
