Description

Technical Field

[0001] The invention relates to the technical field of biostimulant preparation, in particular to a production device for preparing amino acid biostimulant by enzymatic hydrolysis of marine fish protein. Background Art

[0002] The preparation of amino acid biostimulants by enzymatic hydrolysis of marine fish protein is an innovative biotechnology process. It uses specific enzymatic hydrolysis technology to break down marine fish protein into small molecule amino acids and other biologically active substances. These decomposition products are rich in a variety of amino acids and trace elements that are beneficial to plant growth. As biostimulants, they have broad application potential in the agricultural field.

[0003] The patent with publication number CN220597516U discloses a reactor suitable for fish protein hydrolysis, including a sampling port, a sampling tube is fixedly installed on the inner wall surface of the sampling port, a fixing plate is fixedly installed on the outer wall surface of the reactor body, a movable groove is opened on one side surface of the fixing plate, and a sliding rod is fixedly installed between the inner walls on both sides of the movable groove. When the existing fish protein hydrolysis reactor is in use, it is not convenient to open the reactor immediately for sampling and observation due to the high internal temperature of the device. The sampling can only be carried out after the internal temperature drops, which makes the whole sampling process time-consuming and laborious.

[0004] In the traditional fish protein extraction process, the mixture after crushing often contains insoluble impurities such as fish bone fragments and fibers. During filtration, these impurities are retained on the filter medium, while the protein extract flows out. However, this process has limitations: first, after filtration, extra time is required to disassemble the equipment, clean the medium and rinse the reactor, which increases the production cycle and cost; second, due to the water absorption of fish bone fragments and fibers, traditional filtration methods are difficult to fully recover the protein extract; finally, protein extraction and enzymatic hydrolysis reactions are usually carried out in two groups of reactors, and the extract needs to be transported through pipes or other automated devices. Although this reduces the risk of contamination, it also increases the equipment investment cost.

[0005] In view of this, we propose a production device for preparing amino acid biostimulants by enzymatic hydrolysis of marine fish protein. Summary of the invention

[0025] S3, after the pH value of the salt solution is adjusted to acidic by dilute hydrochloric acid, the sealing cover is closed again, and the driving motor in the driving device is started to drive the driving gear to rotate. After the driving gear contacts the cylinder wall ring gear, the centrifugal cylinder as a whole is driven to rotate.

[0032] S10. Subsequently, the enzymatic hydrolysate is subjected to ultrafiltration membrane separation technology to further purify the amino acids and small peptide products, and after removing the macromolecular impurities and salts, the purified products are concentrated and dried to obtain the amino acid biostimulant product prepared by fish protein hydrolysis.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. The production device for preparing amino acid biostimulants by protein hydrolysis of marine fish protein can drive the centrifugal cylinder and the rotating cover to rotate at the same time through the driving motor, and after the electric push rod is started to move the mobile tank upward, the protein extract can be directly poured into the interior of the mobile tank, which saves costs and reduces the time for transferring the protein extract between two processing equipment in the traditional process.

[0035] 2. In the production device for preparing amino acid biostimulants by enzymatic hydrolysis of marine fish protein, while the lifting tube drives the liquid blocking cover to change, the lifting rod will also drive the change of the position of the holding plate in the fish paste processing device. At this time, the limit block will extend to the inside of the groove on the plate surface, and after accelerating the output power of the driving motor, the centrifugal cylinder can be rotated at a high speed together with the holding plate, so as to realize centrifugal filtration of the fish paste inside the centrifugal cylinder and fully recover the protein extract.

[0036] 3. In the production device for preparing amino acid biostimulants by protein hydrolysis of marine fish protein, after the centrifugal cylinder completes centrifugal filtration and the position of the movable tank is restored, the operator can replace the entire fish paste processing device by briefly shutting down the drive motor and clean the centrifugal cylinder in the replaced fish paste processing device, which reduces the cleaning of the inner wall of the protein extraction tank and improves the continuity of the overall production process.

At this time, the protein extract passes through the tube wall filter 133 and the liquid through hole 361 and then flows into the interior of the movable tank 350;
