Embodiment Construction

[0027] Below in conjunction with accompanying drawing, the processing method of the present invention for producing freshwater fish feed from food waste will be described in detail.

[0028] Such as figure 1 Shown, the operation of food waste production freshwater fish feed of the present invention mainly comprises five major operations:

[0029] Process 101: sorting and crushing process. Fresh kitchen waste from canteens and restaurants is manually sorted to remove impurities such as wood, bamboo, plastic, and metal, and is collected and stored in the storage silo. The garbage is transported from the storage silo to the roller screen by a screw conveyor to further remove impurities. Then it is transported to the crusher by the screw conveying device and crushed into clean kitchen waste with a particle size of ≤30mm.

[0030] First of all, guide the staff in the canteens of schools, enterprises and institutions to roughly classify the kitchen waste, and remove large debris s...

Abstract

The invention relates to a method and a system for producing freshwater fish feed by taking canteen kitchen waste as a main raw material. The method comprises: (1) a sorting and crushing process; (2) a mixing and fermenting process; (3) a drying process; (4) a winnowing and grinding process; (5) a granulating and finished product packaging process. The method concretely comprises the steps of carrying out the sorting and crushing process, specifically, removing impurities such as wood and bamboo, plastics and metal of fresh waste with the water content of less than or equal to 80%, crushing the waste without impurities into clean kitchen waste with particle size of less than or equal to 30mm, and conveying the clean kitchen waste into the mixing and fermenting process by using a sealed conveying device; adding materials such as bean pulp and fish meal into the clean kitchen waste according to a pre-mixed fish feed formula, evenly mixing and stirring, then carrying out fermentation, and sending the fermented mixture into the drying process; drying the fermented mixture until the water content of the mixture is less than or equal to 13%, and then sending the obtained material into the winnowing and grinding process; further removing the impurities of the mixture and grinding into powdery material; finally, granulating and packaging to obtain the freshwater fish feed. The method and the system are especially suitable for small and medium-scale resourceful treatment of the kitchen waste.

Description

technical field [0001] The invention relates to the technical field of resource recycling of kitchen waste, in particular to a process method and system for producing feed from kitchen waste, in particular to a process method and system for producing feed for freshwater fish from kitchen waste. Background technique [0002] Kitchen waste is one of the main sources of urban solid waste. At present, the domestic food waste treatment methods are mainly composting and incineration, and resource utilization is relatively small. The invention uses the characteristics of high nutritional value and strong edibility of kitchen waste to prepare safe and high-quality fish feed, which can effectively reconcile the two major needs of feed raw materials and pollution reduction, and is an important supporting technology for the upgrading of environmentally friendly fisheries. Contents of the invention [0003] In view of this, one aspect of the present invention provides a process for pr...
