Fish Protein Water Soluble Fertilizer Production Line

Fish protein water-soluble fertilizer production line uses enzymatic hydrolysis to break down proteins from fish waste into amino acids, Creating water-soluble fertilizers from fish protein. The equipment includes an industrial pure water machine, Raw Material Pulper, High Temperature Sterilization Reactor, Enzymatic Hydrolysis Reactor, Solid-liquid separation equipment, Buffer tank, Robust Measuring Equipment, Liquid Measuring Equipment, Finished Product Cooling Tank and Filling Production Line.

Production Process

1.Preparation of Raw Materials
Fish Raw Materials: Select protein-rich fish or fish by-products, like fish bones, fish skin, Fish Offal, etc.
Other Commodities: Including chelating agents, stabilizers, Preservatives, etc.

2.Processing of Fish Raw Materials
Cleaning: Clean fish raw materials to remove impurities.
Grinding: Crush the fish raw materials to increase the surface area for subsequent hydrolysis treatment.

3.Protein Extraction and Hydrolysis
Enzymatic Hydrolysis: Using protease to hydrolyse fish raw materials, Breaking down proteins into amino acids and small peptides. The enzymatic hydrolysis process requires temperature and pH control to ensure optimal enzyme activity and hydrolysis efficiency.

4.Filtration and Concentration
Filtration: Filter the hydrolyzed mixture to remove undissolved solid impurities.
Concentration: Concentrate the filtered liquid, typically using vacuum concentration or membrane separation technology, to increase the concentration of effective ingredients in the product.

5.Additives
According to the product formula, Add chelating agents, stabilizers, preservatives and other additives, and mix evenly. These additives help improve product stability and shelf life.

6.Mixing and Homogenization
Evenly mix the concentrated liquid with the additives, and perform homogenization if necessary, to ensure product consistency and uniformity.

7.Quality Inspection
Perform quality inspection of the mixed product, including amino acid content, pH value, Heavy metal content, Microbial indicators, etc., to ensure that the product meets relevant standards.

8.Packaging
Packaging Qualified Fish Protein Water-Soluble Fertilizer, usually using moisture-proof and anti-oxidation packaging materials, Seal and label packages.

9.Storage
Store packaged products in a cool, dry warehouse, avoiding direct sunlight and high temperatures.

1.Fish Meat Pulper: The fish meat pulper can completely crush fresh fish meat and fish waste (Fish heads, entrails, fish skin, fish fins, fish scales, Fish tails, fish bones and fish meat waste) to improve the efficiency of enzymatic hydrolysis and reduce impurities.

2.Industrial Pure Water Machine: This machine includes dual-stage filtration with quartz sand and activated carbon, together with RO membrane filtration. Prefiltration can remove particulate impurities, fibres, Suspended solids, colloids, Residual chlorine, Detergents, Organic substances, odors, colors and carcinogens such as trichloromethane. Reverse osmosis membrane intercepts organic salts, heavy metals, chemical contaminants, bacteria, Viruses and pyrogens, which are discharged with concentrated water, while water and oxygen molecules pass through the membrane to form soft water.

3.Enzymatic Hydrolysis Reactor: The reactor has a constant temperature function to ensure a stable temperature during enzymatic hydrolysis. Features a stirring form combined with a built-in scraper cleaning device. An optional stirring speed adjustment function is available, Suitable for various concentrations of raw materials.

4.Three-Stage Series Sealed Filtration: This process uses three-stage series sealed filtration to reduce water-insoluble substances and also to reduce equipment investment costs.

5.Closed Buffer Tank: The use of an enclosed buffer tank reduces the risk of deterioration of the semi-finished product.

6.Element Digester: The element digester in the fertilizer production stage has chelation and complexation functions and is equipped with a constant temperature function.

7.Addition of Amino Acid Powder: During the fertilizer production stage, amino acid powder raw materials can be added to increase the amino acid content of the final product.

8.Cooling Coil in the Finished Product Tank: The finished product tank is equipped with a cooling coil, that circulates water connected to a cooling tower, to cool the fertilizer product inside the tank.
