Common Processing Issues in Liquid Fish Fertilizer Manufacturing

Common Processing Issues in Liquid Fish Fertilizer Manufacturing

Liquid fish fertilizer manufacturing requires steady processing conditions, consistent raw materials, and dependable equipment. The process can bring strong profits, but producers often face practical challenges during fish residue liquid fertilizer production. Common issues include unstable hydrolysis, odor control, filtration problems, and equipment corrosion. Understanding these risks in advance helps investors design a more efficient production line and avoid costly downtime.

Why does the fish protein hydrolysis process often become unstable?

Because raw fish waste varies in fat level, viscosity, and freshness. many fertilizer producers struggle to keep the hydrolysis reaction stable. These fluctuations slow down enzymatic breakdown and create inconsistent amino acid profiles. Temperature deviations during the reaction also reduce enzyme efficiency. Solution: A stable hydrolysis line needs accurate temperature control, pH monitoring, and reliable agitation. YUSHUNXIN provides automatic hydrolysis tanks with precise heating jackets, digital sensors, and high-torque mixers. These systems keep the reaction uniform and improve protein conversion rates.

Why does solid fish residue frequently block pumps and pipes?

In fish-based organic fertilizer liquid production, scales, bones, and fibrous tissues often clump together. These residues obstruct pumps, overload pipelines, and interrupt continuous production. Solution: Pre-filtration and solid reduction reduce these issues. YUSHUNXIN recommends a screw-press solid-liquid separator. It can remove large particles and reduce the solid load before hydrolysis. Meanwhile, you can customize a precision filter in the fermentation tank to remove impurities. It effectively prevents pipe choking during the later pumping stage.

What causes unpleasant odors during liquid fish fertilizer manufacturing?

This problem often affects smaller fertilizer producers lacking stable temperature control. Because strong odors usually appear when hydrolysis remains incomplete or when bacteria grow rapidly in warm, nutrient-rich slurry.

  • Solution: For this, YUSHUNXIN provides closed hydrolysis reactors and sanitary transfer systems that limit contamination. Пры гэтым, stainless-steel fermentation tanks with optional UV sterilization maintain microbial balance and help create cleaner, higher-quality liquid fish fertilizer manufacturing.

4.Why does the final fertilizer sometimes foam or stratify during storage?

  • Foaming happens when proteins remain partially hydrolyzed. Stratification occurs when tiny solid particles settle at the bottom and oil rises to the top. Both issues reduce product quality and customer confidence.
    Solution: ЮШУНЬСІНЬ offers high-shear homogenizers to stabilize the mixture before packaging. This process creates uniform particle size and prevents separation during storage.

How to avoid corrosion in the fish amino acid fertilizer manufacturing line?

Fish protein liquids contain salts, organic acids, і ферменты. These materials can corrode low-grade metals quickly. Poor material selection increases maintenance costs.

Solution: We build all contact surfaces with 304 stainless steel, which resists saltwater corrosion. This raises liquid fertilizer production equipment and reduces downtime.
