Description

Technical Field

[0001] This utility model relates to the technical field of waste co-processing equipment, specifically a fermentation and mixing mechanism for green waste and kitchen waste. Background Technology

[0002] Green waste and kitchen waste are two common types of organic waste in cities. Individual treatment has significant limitations. While mixed treatment has synergistic potential, existing technologies suffer from poor pretreatment compatibility. For example, green waste contains a large amount of long fibers, requiring high-intensity crushing; kitchen waste contains impurities such as plastic bags and metals, requiring fine impurity removal. A single pretreatment process can lead to either excessively coarse fibers clogging the equipment or low fermentation efficiency after mixing the two types of waste. Furthermore, the fermentation environment is difficult to coordinate. Green waste fiber decomposition requires higher oxygen concentrations and longer turning cycles, while kitchen waste fermentation requires precise temperature control and anti-caking. Additionally, localized anaerobic digestion or over-composting can easily occur during fermentation, and the exhaust gas generated from mixed fermentation is not thoroughly treated, posing a high risk of secondary pollution. Existing technologies struggle to achieve efficient synergistic fermentation of these two types of waste. Therefore, we propose a mixed fermentation mechanism for green waste and kitchen waste.
