Procurement Instructions for Fish Meal Protein Powder Enzymatic Hydrolysis Fish Meal Processing Equipment

Fish syrup is the squeezed wastewater generated during the production of fish meal. Every ton of fish meal produced will produce two to three times the amount of fish syrup. In the previous fishmeal production process, fish paste 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 more research on how to use fish paste, such as the production of food grade umami (CN107136465A) using fish paste, the obtained umami is easy to absorb, the umami is sufficient, or the fish paste is used Preparation of protein fertilizer (CN105060944A) not only provides nutrients for crops and increases production, but also improves soil conditions and promotes healthy growth of crops. Because fish pulp is derived from marine fish, it has a fishy peculiar smell. After the hydrolysis process, other flavor substances are produced, which is a high-quality feed additive.

Hydrolysis method A production method of grinding pump to grind the hydrolyzed fish slurry, specifically including the following steps:

Inject 200 parts of fish paste into the heating cooking device, cook at 85°C for 40 min at high temperature for sterilization and killing enzymes, and after cooling, add Lactobacillus plantarum, Lactococcus lactis and Lactobacillus brevis complex, inoculation amount 5%, in 30 Fermentation at ℃ for 3 days, after the fermentation is completed, 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 enzymolysis for 2 hours Afterwards, the vacuum distillation is performed again to remove excess water, and the enzyme killing effect is achieved while concentrating. When the water content is reduced to 45%, the heating is stopped, and then an AC electric field with a strength of 60V/cm is applied for 6 minutes. After cooling, it can be filled. Hydrolyzed fish paste products.

(1) Blending: Add appropriate amount of water to the fish lye stock solution to make a fish lye with 80% water content.

(2) Sterilization: Increase the temperature to 90 degrees and sterilize using infrared rays.

(3) Separation of crude fat: The resulting fish slurry is sent to a horizontal centrifuge and a butterfly centrifuge successively to separate the crude fat in it until the residual amount is less than 1%.

(4) Removal of salt: The resulting fish paste is passed through a resin separation device to remove the salt in the fish paste until its content is less than 0.04%.

(5) Enzymatic hydrolysis: Add 1% PROTEXP enzyme to carry out enzymatic hydrolysis at 45 degrees water temperature for 4 hours to make the fish lysate into small molecules.
