Drying system for kitchen waste treatment

Abstract

The invention discloses a drying system for kitchen waste treatment, and belongs to the technical field of kitchen waste treatment devices. The drying system comprises a drying container, a first drying circulation pipeline, a second drying circulation pipeline, a stirring assembly and a heating stirring assembly, wherein the drying container is provided with a drying chamber; the first drying circulation pipeline communicates with the drying chamber and is provided with a first drying condensing assembly and a first fan; the second drying circulation pipeline communicates with the drying chamber and is provided with a second drying and condensing assembly and a second fan; the stirring assembly is arranged in the drying chamber; the heating assembly is used for heating the drying chamber;and the drying system comprises a first drying state and a second drying state. According to the drying system, along with the gradual decrease in the water content in solid wastes in the drying process, the solid wastes can be dried through the first drying circulating pipeline and the second drying circulating pipeline correspondingly in the case of high water content and low water content in the solid wastes, so that the drying speed can be greatly improved and the energy consumption can be reduced on the premise of ensuring the drying effect.

Description

technical field [0001] The invention relates to the technical field of kitchen waste treatment devices, in particular to a drying system for kitchen waste treatment. Background technique [0002] Garbage classification is a reform of the traditional way of garbage collection and disposal, and a scientific management method for effective disposal of garbage. Facing the ever-increasing garbage production and the deteriorating environmental conditions, how to maximize the utilization of garbage resources, reduce the amount of garbage disposal, and improve the quality of living environment through garbage classification management is one of the urgent issues of common concern to all countries in the world. . [0003] Food waste is the most important type of food waste, including food processing waste (kitchen waste) and food residue (swill) produced by families, schools, canteens and catering industries. Its composition is complex, mainly oil, water , fruit peels, vegetables, ...

AI Technical Summary

Problems solved by technology

Existing drying systems for solid waste usually use flowing drying air to dry quickly. This method has the following disadvantages: 1. The cycle of drying with drying air is long, and it is difficult to dry completely, and the remaining Moisture on solid waste can accelerate the decomposition, fermentation, and decay of solid waste, affecting the classification and recycling of solid waste; 2. The drying air will produce a large amount of odorous gas during the drying process. If this gas is directly discharged into the atmosphere In the process of drying, it will also pollute the ecological environment; 3. In the drying process, continuous input of drying wind is required, and the energy consumption is huge
