Description

Technical Field

[0001] This utility model relates to the field of enzyme reactor technology, specifically to an ultrasonic-assisted enzymatic hydrolysis reactor for sea cucumber peptides. Background Technology

[0002] Sea cucumber, a high-protein, low-fat marine biological resource, is rich in collagen, mucopolysaccharides, saponins, and other bioactive components. Sea cucumber peptides, produced through enzymatic hydrolysis, possess various physiological functions such as easy absorption, antioxidant activity, and immune regulation, showing broad application prospects in health products, functional foods, and pharmaceuticals. Therefore, the efficient extraction and preparation of sea cucumber peptides has become an important direction in the current field of aquatic product deep processing and bioactive peptide research.

[0003] Existing technology includes an enzyme reactor disclosed in patent application number CN202320513524.5, comprising an enzyme reactor tank, a drive motor installed at the center of the top of the enzyme reactor cover, the drive shaft of the drive motor connected to a stirring shaft, and telescopic crossbars fixedly connected to both sides of the bottom end of the stirring shaft. A stirrer is installed at the other end of the telescopic crossbars, and the stirrer includes a rubber scraper and a nested vertical rod. The rubber scraper has a rubber scraper notch, and the nested vertical rod has a nested vertical rod protrusion. The rubber scraper is nested and connected to the nested vertical rod protrusion through the rubber scraper notch. The stirrer of this invention is made of rubber and is placed upright close to the inner wall. The vortex generated during operation can stir the reactants, providing a gentle and low-damage stirring effect. During cleaning, the stirrer can be brought into contact with the inner wall of the reactor, and an external cleaning agent can be used to achieve a rotating scraping effect, ultimately cleaning the residue on the inner wall. However, existing ultrasonic-assisted enzymatic hydrolysis equipment still has many shortcomings in practical applications: On the one hand, the ultrasonic generator is mostly fixed to the outer wall of the reaction vessel, resulting in low energy transfer efficiency, and the ultrasonic waves are unevenly distributed in the material, leading to insufficient enzymatic hydrolysis in some areas, which affects the yield and quality of sea cucumber peptides; on the other hand, during the reaction, sea cucumber raw materials and enzymatic hydrolysis products are prone to adhere to the inner wall of the reaction vessel, which not only wastes materials, but also affects the overall reaction effect due to incomplete enzymatic hydrolysis of locally adhered materials, increasing the difficulty of subsequent cleaning; in addition, the synergy between stirring and ultrasonic action in most equipment is poor, making it impossible to achieve full mixing of materials and efficient utilization of ultrasonic energy, resulting in limited improvement in enzymatic hydrolysis reaction efficiency.

[0004] In view of this, we propose an ultrasonic-assisted enzymatic hydrolysis reactor for sea cucumber peptides. Utility Model Content

[0005] To overcome the above shortcomings, this invention provides an ultrasonic-assisted enzymatic hydrolysis reactor for sea cucumber peptides.

[0006] The technical solution of this utility model is:

[0007] The sea cucumber peptide ultrasonic-assisted enzymatic hydrolysis reactor includes a reaction vessel. An ultrasonic generator is fixedly installed on the outer wall of the reaction vessel. A support frame is fixedly installed near the top inside the reaction vessel. A fixed rod is fixedly installed at the bottom of the support frame. Several ultrasonic generating tips are embedded in the outer circumference of the fixed rod. A rotating frame is rotatably mounted on the outer circumference of the fixed rod via two symmetrically arranged bearings. Two strip-shaped openings are symmetrically opened on the rotating frame. The width of the strip-shaped openings is larger than the diameter of the ultrasonic generating tips. Several stirring blades are fixedly installed on the outer circumference of the rotating frame. A scraper is fixedly installed at the end of the stirring blades away from the rotating frame. A scraper blade is fixed on the scraper and fits tightly against the inner circumference of the reaction vessel. By setting the ultrasonic generator on the outer wall of the reaction vessel and embedding multiple ultrasonic generating tips in the internal fixed rod, ultrasonic energy can be efficiently generated to promote the enzymatic hydrolysis reaction of sea cucumber peptides. At the same time, the rotating frame drives the stirring blades and scraper blades to rotate, which not only achieves material stirring and makes the enzymatic hydrolysis more uniform, but also prevents material adhesion by scraping the inner wall of the reaction vessel, thereby improving reaction efficiency and product quality.

[0008] As a preferred technical solution, the reaction vessel is provided with a feeding port at the top, and a sealing cap is installed at the feeding port. This facilitates the addition of sea cucumber raw materials and enzyme preparations to the vessel, while the sealing cap prevents material leakage or the entry of external impurities during the reaction process.

[0009] As a preferred technical solution, a feeding hopper communicating with the interior is installed on both sides of the top of the reaction vessel. Each feeding hopper is fitted with a funnel cover and a feeding valve. This facilitates the replenishment of materials or additives during the reaction process, allows for precise control of the feeding amount and timing according to the reaction progress, and improves the controllability of the reaction.

[0010] As a preferred technical solution, both the rotating frame and the fixed rod extend from the bottom of the reaction vessel. A driven gear is coaxially welded to the bottom of the outer circumference of the rotating frame. A drive gear meshing with the driven gear is rotatably mounted at the bottom of the reaction vessel. An L-shaped mounting plate is fixedly mounted at the bottom of the reaction vessel, and a stirring motor with its output shaft coaxially fixed to the drive gear is mounted on the L-shaped mounting plate. The rotating frame is powered by the stirring motor driving the drive gear meshing with the driven gear.

[0011] As a preferred technical solution, the bottom of the reaction vessel is equipped with several support legs arranged in a circular array. This provides stable support for the reaction vessel and ensures the stability of the equipment during operation.

[0012] As a preferred technical solution, a discharge port is provided on the outer wall of the reaction vessel near the top, and a sealing baffle is fixedly installed on the outside of the discharge port by bolts. This facilitates the discharge of materials after the enzymatic hydrolysis reaction is completed.

[0013] As a preferred technical solution, two handles are symmetrically fixedly installed on the top of the sealing cover, and the handles are U-shaped. This facilitates the opening and closing of the sealing cover by the operator, improves operational convenience, and reduces labor intensity.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes an ultrasonic generator installed on the outer wall of the reaction vessel and multiple ultrasonic generating heads embedded in the internal fixing rod to efficiently generate ultrasonic energy to promote the enzymatic hydrolysis of sea cucumber peptides. At the same time, the rotating frame drives the stirring blades and scrapers to rotate, which not only achieves material stirring and makes the enzymatic hydrolysis more uniform, but also prevents material adhesion by scraping the inner wall of the reaction vessel, thereby improving reaction efficiency and product quality.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] The sea cucumber peptide ultrasonic-assisted enzymatic hydrolysis reactor includes a reaction vessel 1. An ultrasonic generator 2 is fixedly installed on the outer wall of the reaction vessel 1. A support frame 10 is fixedly installed near the top inside the reaction vessel 1. A fixed rod 13 is fixedly installed at the bottom of the support frame 10. Several ultrasonic generator tips 14 are embedded in the outer circumference of the fixed rod 13. A rotating frame 11 is rotatably installed on the outer circumference of the fixed rod 13 through two symmetrically arranged bearings 112. Two strip-shaped openings 110 are symmetrically opened on the rotating frame 11. The width of the strip-shaped openings 110 is larger than the diameter of the ultrasonic generator tips 14. Several stirring blades 12 are fixedly installed on the outer ring wall of the rotating frame 11. A scraper 15 is fixedly installed at the end of the stirring blade 12 away from the rotating frame 11. A scraper blade 16 is fixed on the scraper blade 15 and is in close contact with the inner ring wall of the reaction vessel 1. By setting an ultrasonic generator 2 on the outer wall of the reaction vessel 1 and embedding multiple ultrasonic generating heads 14 on the internal fixing rod 13, ultrasonic energy can be efficiently generated to promote the enzymatic hydrolysis reaction of sea cucumber peptides. At the same time, the rotating frame 11 drives the stirring blade 12 and scraper 15 to rotate, which not only achieves material stirring to make the enzymatic hydrolysis more uniform, but also prevents material adhesion by scraping the inner wall of the reaction vessel 1 with the scraper 16, thereby improving reaction efficiency and product quality.

[0025] In a preferred embodiment, the reaction vessel 1 is provided with a feeding port at the top, and a sealing cap 4 is installed at the feeding port. This facilitates the addition of sea cucumber raw materials and enzyme preparations to the vessel, and the sealing cap 4 prevents material leakage or the entry of external impurities during the reaction process.

[0026] In a preferred embodiment, a feeding hopper 3 is installed on both sides of the top of the reaction vessel 1, communicating with its interior. A funnel cover 30 is installed on the feeding hopper 3, and a feeding valve 31 is installed on the feeding hopper 3. This facilitates the replenishment of materials or additives during the reaction process, and allows for precise control of the feeding amount and timing according to the reaction progress, improving the controllability of the reaction.

[0027] In a preferred embodiment, both the rotating frame 11 and the fixed rod 13 extend from the bottom of the reaction vessel 1. A driven gear 111 is coaxially welded to the bottom of the outer circumference of the rotating frame 11. A drive gear 19, meshing with the driven gear 111, is rotatably mounted at the bottom of the reaction vessel 1. An L-shaped mounting plate 17 is fixedly mounted at the bottom of the reaction vessel 1, and a stirring motor 18, whose output shaft is coaxially fixed with the drive gear 19, is mounted on the L-shaped mounting plate 17. The rotating frame 11 is powered by the stirring motor 18 driving the drive gear 19, which meshes with the driven gear 111.

[0028] In a preferred embodiment, the bottom of the reaction vessel 1 is equipped with a plurality of legs 5 arranged in a circular array. These legs provide stable support for the reaction vessel 1, ensuring the stability of the equipment during operation.

[0029] As a preferred embodiment, a discharge port is provided on the outer wall of the reaction vessel 1 near the top, and a sealing baffle 6 is fixedly installed on the outside of the discharge port by bolts. This facilitates the discharge of materials after the enzymatic hydrolysis reaction is completed.

[0030] In this preferred embodiment, two handles 40 are symmetrically fixedly installed on the top of the sealing cover 4. The handles 40 are U-shaped. This facilitates the opening and closing of the sealing cover 4 by the operator, improves operational convenience, and reduces labor intensity.

[0031] When using the ultrasonic-assisted enzymatic hydrolysis reactor for sea cucumber peptides of this invention:

[0032] First, the operator adds the sea cucumber raw material, protease, and other materials required for enzymatic hydrolysis to the reaction tank 1 through the feeding port at the top of the tank. Then, the sealing cap 4 is tightly closed to ensure the airtightness of the reaction environment and prevent material leakage or the entry of external impurities. If materials or additives need to be added during the reaction, this can be done through the feeding hoppers 3 on both sides of the top. By controlling the opening and closing of the feeding valve 31, the amount and timing of material addition can be precisely adjusted to meet the material replenishment needs during the reaction.

[0033] After the equipment is started, the ultrasonic generator 2 begins to work, and the ultrasonic energy it generates is released into the material in the reaction tank 1 through multiple ultrasonic generating heads 14 on the fixed rod 13. Since the ultrasonic generating heads 14 are embedded in the outer circumference of the fixed rod 13, and the rotating frame 11 has a strip-shaped opening 110 with a width greater than the diameter of the ultrasonic generating heads 14, the rotating frame 11 will not interfere with the ultrasonic generating heads 14 when it rotates, ensuring that the ultrasonic energy can act on the material continuously and evenly. By utilizing the cavitation effect and mechanical vibration of the ultrasonic waves, the cell structure of the sea cucumber raw material is destroyed, the contact between the protease and the sea cucumber components is promoted, and the enzymatic hydrolysis reaction is accelerated.

[0034] Meanwhile, the stirring motor 18 is fixed to the bottom of the reaction vessel 1 via an L-shaped mounting plate 17. Its output shaft drives the drive gear 19 to rotate, and the drive gear 19 meshes with the driven gear 111 at the bottom of the rotating frame 11, thereby driving the rotating frame 11 to rotate around the fixed rod 13. When the rotating frame 11 rotates, the stirring blades 12 on its outer ring wall stir the material in the vessel, ensuring that the sea cucumber raw material, protease, and ultrasonic energy come into full contact, avoiding local aggregation of materials, and ensuring uniform enzymatic hydrolysis. In addition, the scraper 15 at the end of the stirring blade 12 rotates synchronously with the rotating frame 11. The scraper blades 16 on the scraper 15 are in close contact with the inner ring wall of the reaction vessel 1, which can promptly scrape off the material adhering to the inner wall, preventing the material from affecting the enzymatic hydrolysis efficiency due to prolonged retention, and also avoiding material waste.

[0035] Throughout the enzymatic hydrolysis process, the support legs 5 at the bottom of reaction tank 1 provide stable support, ensuring that the equipment does not shake under stirring and ultrasonic action, thus guaranteeing the stability of the reaction. After the enzymatic hydrolysis reaction is completed, the operator can open the sealing baffle 6 at the discharge port on the outer wall of reaction tank 1 to discharge the reacted sea cucumber peptide solution, completing the entire enzymatic hydrolysis operation.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
