Reducing the fermentation time of liquid fertilizer is a key concern for many liquid fertilizer suppliers. Anaerobic fermentation normally requires weeks, but with the right process and equipment, this period can be significantly shortened. Three important factors—temperature control, fermentation promoters, and raw material size—directly influence the speed of decomposition and the stability of the final product.
Large and fibrous raw materials, such as fish bones, scales, and viscera, take longer to decompose. By crushing the raw material into smaller particles, the surface area increases and microorganisms contact nutrients more efficiently. This direct contact speeds up the breakdown of proteins and fats. YUSHUNXIN’S double shaft shredder is designed for handling high-moisture organic waste, especially fish residues. The machine reduces particle size quickly, prevents clogging, and ensures uniform input for the anaerobic fermentation tank. With proper crushing, you can shorten the fermentation time of liquid fertilizer.
Temperature is the most critical factor in the fermentation process. Microbes work best in a stable environment, ideally between 30–37℃. Fluctuations in heat reduce microbial activity and extend processing time. The YUSHUNXIN anaerobic fermentation tank solves this challenge. Made of 304 stainless steel, it resists corrosion from fish waste and other organic inputs. The tank includes a precise heating and stirring system that maintains a constant temperature and ensures even mixing. With stable heat, organic matter decomposes faster, fermentation becomes more efficient, and the final liquid fertilizer is more stable.

During anaerobic fermentation, the carbon-to-nitrogen ratio often needs adjustment for faster microbial activity. You can add small amounts of molasses, urea, or trace elements to supply balanced nutrients. In many cases, the dosage ranges from 1% to 3% of the total mixture, depending on raw material quality. These supplements not only shorten fermentation time but also improve the stability and nutrient profile of the final liquid fertilizer. To achieve accurate dosing, YUSHUNXIN provides a stainless steel dosing tank system with stirring and metering functions. This equipment helps operators control additive levels precisely, which ensures consistent and efficient liquid fertilizer manufacturing.
By combining raw material crushing, precise temperature control, and accurate additive dosing, you can significantly reduce the fermentation time of liquid fertilizer to 3 days. Welcome to consult us!
