Q&A: Can chicken manure be fed directly into a bio-organic fertilizer production line without drying?
A: Generally, fresh chicken manure does not require drying and can be fed directly into the bio-organic fertilizer production line . Drying is not a necessary preliminary step; in fact, high-temperature drying kills beneficial microorganisms and causes a loss of organic matter—a common pitfall for beginners. The core of bio-organic fertilizer production is decomposition and fermentation, not raw material drying; moist chicken manure is actually more conducive to microbial proliferation. However, there are strict moisture standards for direct processing. Fresh chicken manure typically has a moisture content of 70%–80%, which is unsuitable for immediate fermentation and granulation. Pre-treatment is required: dry additives such as straw, sawdust, or rice husks are mixed in to adjust the moisture content to 55%–60% and balance the carbon-to-nitrogen ratio. Once adjusted, the material can proceed directly to the turning and fermentation stage without drying. A wet-material fermentation pro...
