The multifunctional pulp mill grinds and smashes fish pulp in one step, which saves energy and reduces emissions.The multifunctional pulp mill is a new generation of colloid mill pump type for online crushing of crushed and ground fish soluble pulp, one step in place, energy saving and emission reduction. The use of Zhejiang Haoxing machinery and equipment to manufacture in-line fish protein colloidal fish pulp grinder grinding pump can process fish, shrimp, fish, squid paste, etc. to produce fish protein feed and water-soluble fertilizers. Compared with similar products, it has been down for one year. It can save about 60,000KW of electricity. The fish pulp is made of natural deep-sea fish as raw materials and processed by advanced biotechnology; high-temperature cooking, enzymatic hydrolysis, juice pressing, crushing, grinding, homogenization, centrifugation, vacuum concentration and other processes are refined. Contains all the nutrients of fish: fish protein, which is an excellent food attractant and nutritional supplement in aquatic, poultry and livestock feed. Fish soluble protein proteolysis fish meal processing equipment is basically introduced. Fish soluble protein, water soluble feed and fertilizer. Fish soluble protein, also known as fish soluble protein peptide powder, biochemical liquid fish meal, is based on anchovy, shrimp, deep-sea cod steak, etc. as the main raw materials. After cooking and auger, it is sent to Haoxing grinding pump (multifunctional pulp mill-a new generation of colloid mill machine) for processing, crushing, grinding, pulping, juice pressing, concentration, and low-temperature spray-drying powder products. Its main ingredients are free protein, low molecular weight peptides, nucleic acids, water-soluble vitamins and trace elements, so it has a strong attraction and nutrition and health function. 1.

The equipment and supporting facilities used in this process include single-layer pressure-resistant liquid storage tanks, single-effect falling film concentration, and centrifugal spray drying towers. Instructions for purchasing fish meal processing equipment for enzymatic hydrolysis of fish soluble protein powder Overview of the application of fish pulp (partly taken from the Internet)[1][2] Fish lysate is the squeezed waste water produced during the production of fish meal. For every ton of fish meal produced, two to three times as much fish lysate is produced. In the previous fishmeal production process, the fish pulp was usually discharged directly into the environment, which not only wasted this protein-rich resource, but also caused serious environmental pollution. In recent years, industry researchers have done a lot of research on how to use fish pulp, such as the use of fish pulp to produce food-grade umami (CN107136465A). The obtained umami agent is easy to absorb and has sufficient savory flavor, or the use of fish soluble pulp The preparation of protein fertilizer can not only provide nutrients to crops and increase yield, but also improve soil conditions and promote healthy growth of crops. Because the fish pulp is derived from marine fish, it has a unique fishy smell. After the hydrolysis process, other flavor substances are produced. It is a high-quality feed additive. Hydrolysis method [1] A production method of hydrolyzed fish pulp, specifically including the following steps: Inject 200 parts of fish lysate into the heating and cooking device, and cook at 85°C for 40 minutes to sterilize and kill enzymes. After cooling, add Lactobacillus plantarum, Lactococcus lactis, and Lactobacillus brevis complex bacteria. The inoculation amount is 5%. Fermented at ℃ for 3 days, after the fermentation, adjust the pH to 10.0 with an appropriate amount of 3mol/L sodium hydroxide solution, stir evenly, add 1.5wt% alkaline protease, and continue to stir at 75℃ for enzymatic hydrolysis, enzymatic hydrolysis for 2 hours After that, vacuum distillation is performed again to remove excess water, and the concentration is at the same time to inactivate the enzyme. When the water content is reduced to 45%, stop heating, and then apply 60V/cm AC electric field for 6min, and then canned after cooling. The finished product of hydrolyzed fish pulp. Application [2-3] A process for producing fish peptone by using fish lysate, including the following steps: (1) Blending: Take appropriate amount of water and add it to the stock solution of fish soluble slurry to form a fish soluble slurry with 80% water content. (2) Sterilization: increase the temperature to 90 degrees and use infrared rays for sterilization. (3) Crude fat separation: The obtained fish soluble slurry is sent to a horizontal centrifuge and a butterfly centrifuge to separate the crude fat in it until the residual amount is less than 1%. (4) Salt removal: the obtained fish lysate is passed through a resin separation device to remove the salt in the fish lysate until its content is less than 0.04%. (5) Enzymatic hydrolysis: add 1% PROTEXP enzyme and carry out enzymatic hydrolysis at 45 degrees water temperature for 4 hours to make the fish lysate into small molecules. (6) Grinding, homogenization and emulsification: After mixing maltodextrin and modified starch according to a certain ratio, add them to the fish soluble slurry, and pass the new generation of Haoxing colloid mill-pipeline grinding pump-multifunctional pulp mill (Using unit: Ocean God Group, Rongcheng Haisheng Feed Co., Ltd., Guangzhou Genda Agricultural Technology Development Co., Ltd., Ningbo Haizhongyuan Biological Technology Co., Ltd., Rongcheng Hefeng Biological Technology Co., Ltd. and other water-soluble slurry feed and water-soluble fertilizer production plants) grinding pumps at home and abroad Compared with colloid mills of similar or same model specifications, the electricity can be saved by 50-60%, and the grinding disc (rotor and stator) is also low in grinding loss, which is energy-saving and high-efficiency. Then enter the high-pressure homogenizer together to homogenize and emulsify. (7) Concentration: The obtained fish lysate is sent to a vacuum low-temperature concentration tank, the temperature is controlled at 60 degrees, the vacuum is -0.095, and the fish lysate with 40% water content is obtained in 4 hours.
