Chicken manure, due to its high nutrient content and rich organic matter, is an excellent raw material for producing organic fertilizer. However, its high moisture content, high viscosity, and high nitrogen content place special demands on processing equipment. The chicken manure organic fertilizer complete production line is a specialized production system designed specifically for these raw material characteristics. Its process flow covers the entire process, including raw material pretreatment, fermentation, crushing, batching and mixing, granulation, drying and cooling, screening, and packaging. The fermentation section is the starting point and core of the entire production line.

Given the high nitrogen and high moisture characteristics of chicken manure, the fermentation stage typically employs a trough-type aerobic fermentation process, equipped with a chain turner to throw, aerate, and mix the compost material in the fermentation trough. The chain plate turner uses a high-speed rotating chain plate structure, resulting in high turning efficiency and thorough turning, effectively shortening the fermentation cycle and improving compost quality. For large-scale farms, fully automatic chain plate turners have become the standard configuration for chicken manure composting processes. After fermentation and composting, the material enters the pre-processing section. The high-moisture chicken manure fermentation material first undergoes coarse crushing in a semi-wet material crusher to break up large clumps. Long-fiber materials are then cut to less than 3-5 cm using a chaff cutter or crusher to increase specific surface area. The crushed material then enters the batching and mixing system, where auxiliary materials and functional microbial agents are added as needed, before proceeding to the granulation stage.

Given the high viscosity of chicken manure raw materials, disc granulators are a common choice for chicken manure organic fertilizer granulation due to their simple operation, high pelletizing rate, and low cost. The granulated wet pellets undergo dehydration in a rotary dryer, cooling in a cooler, grading by a screening machine, and finally packaging by an automatic packaging machine. The entire chicken manure organic fertilizer production line also requires an odor and dust removal system to control ammonia and dust emissions generated during fermentation and drying.

The investment scale of a complete chicken manure organic fertilizer production line can be flexibly designed according to the raw material processing capacity, with mature solutions available for everything from small-scale equipment processing a few tons per day to industrial-scale production lines processing hundreds of tons per day. For large-scale chicken farms, building a chicken manure organic fertilizer production line not only solves the environmental pressure of waste disposal, but also transforms the original disposal costs into sales revenue from organic fertilizer products, achieving a balance between environmental and economic benefits.
