Method for treating food and beverage refuse into fodder and complete equipment

Abstract

The present invention relates to the method and system for treating restaurant and catering refuse into fodder. The treating process includes crushing, dewatering, secondary crushing, drying, sterilizing, mixing with additive, palletizing, oil-water separation of effluent, aerating waste water and other steps. The system includes various apparatus to complete the said steps and all the apparatus are inside one sealed cylinder for automatic closed running. By means of the method and system of the present invention, restaurent and catering refuse may be produced into granulated fodder reaching relevant sanitary and nutritive standards.

Description

Technical field [0001] The invention relates to a method for treating catering waste into feed and a complete set of equipment used for the method. Background technique [0002] Catering waste is mainly composed of leftovers and other waste food. If it is directly discarded or disposed of as general urban waste, it will not only pollute the environment and increase the amount of urban waste to be processed, but also cause waste of these waste foods. At present, some people directly treat these wastes as Feed, but it is easy to spoil during the storage and transportation process, and the harmful microorganisms such as germs and viruses contained in it will also infect the raised livestock, and then cause harm to people. In order to overcome these problems, people began to discuss the feed treatment of food waste It is hoped that it can be used as feed after eliminating harmful microorganisms. For example, Chinese patent application No. 00123345.9 discloses a treatment method ...

[0002] Catering waste is mainly composed of leftovers and other waste food. If it is directly discarded or disposed of as general urban waste, it will not only pollute the environment and increase the amount of urban waste to be processed, but also cause waste of these waste foods. At present, some people directly treat these wastes as Feed, but it is easy to spoil during the storage and transportation process, and the harmful microorganisms such as germs and viruses contained in it will also infect the raised livestock, and then cause harm to people. In order to overcome these problems, people began to discuss the feed treatment of food waste It is hoped that it can be used as feed after eliminating harmful microorganisms. For example, Chinese patent application No. 00123345.9 discloses a treatment method and related equipment for food waste. The method includes four steps: pyrolysis, extrusion dehydration, melting and drying. , and finally turn the waste into feed with low water content. The disadvantage of this method is that the waste material needs to be smelted, especially pyrolysis is required before dehydration, so the energy consumption is relatively large, and the produced feed has a certain The powder bulk material with water volume is inconvenient for storage and transportation, and the nutrient content is not reasonable, which is not conducive to the scientific feeding of livestock
