The organic fertilizer turning machine plays a crucial role in the process of processing wet materials (such as livestock manure, kitchen waste, biogas residue, and other high humidity organic waste) into fertilizers. This type of wet material has a high moisture content and is difficult to handle using traditional composting methods. However, organic fertilizer composting machines can effectively address this challenge. The following is the specific processing procedure:
1. Material pretreatment
Dehydration: High humidity materials first need to undergo solid-liquid separation to reduce their moisture content to an appropriate level for subsequent processing. For livestock and poultry manure, an extruder or centrifuge can be used for preliminary dehydration; For kitchen waste, water can be reduced through pressing and other methods.
2. Add auxiliary materials
Mixing water absorbing materials: In order to balance moisture and provide the carbon source required by microorganisms, it is necessary to add auxiliary materials with strong water absorption properties such as straw, sawdust, rice husks, etc., and adjust the carbon nitrogen ratio (C/N ratio) to about 30:1 to promote microbial growth.
3. Early stage of fermentation
Loading: Place the pre processed material evenly on the fermentation bed or in the fermentation tank to form a fermentation pile.
4. Ventilation and flipping
Intervention of compost turning machine: The organic fertilizer compost turning machine uses its specially designed mixing and flipping structure to pass through the material pile, turning the bottom material to the surface while introducing fresh air to ensure sufficient oxygen supply, promote aerobic microbial activity, and accelerate organic matter decomposition.
5. Control temperature and humidity
Temperature monitoring: Continuously monitor the temperature of the stack through internal or external sensors to ensure it remains between 50 ° C and 65 ° C, which is the optimal temperature range for most fermentation bacteria.
Humidity adjustment: During the flipping process, add water moderately or adjust the evaporation of water by flipping to maintain a suitable humidity for the entire stack, neither too wet nor too dry.
6. Regularly flip the pile
Frequent flipping: Every few days to a week, use a organic fertilizer compost turning machine for thorough flipping to ensure that all materials have sufficient aeration and fermentation opportunities, avoiding local overheating or hypoxia.
7. Maturity stage
Observation: As the fermentation progresses, the material gradually becomes dark, odorless, and has a loose texture, indicating that the fermentation is basically complete.
8. Post processing
Crushing and screening: The fermented material is further processed by a crusher to make it smaller particles, which is beneficial for later use.
Drying: Use sun exposure or a dryer to reduce the moisture content of the final product, making it easier to store and transport.
summary
The organic fertilizer turning machine effectively solves the problem of wet material processing by optimizing fermentation conditions, not only improving fermentation efficiency but also ensuring the quality of the final fertilizer. The application of this technology is widely used in the resource utilization of agricultural waste, helping to protect the ecological environment and promote sustainable agricultural development.
