Description

Technical Field

[0001] The invention relates to the technical field of oyster peptide extraction, and in particular to an automated enzymatic hydrolysis and enzyme inactivation integrated device for oyster peptide production and a use method thereof. Background Art

[0002] Oysters are rich in protein, slightly cold in nature, salty in taste, and belong to the liver meridian, gallbladder meridian, and kidney meridian. They have the effects of enhancing immunity, sedation, anti-experimental gastric ulcer, anti-atherosclerosis, anti-inflammatory and anti-aging. Therefore, they are often favored by people as one of the supplements with high nutritional value.

[0003] Oyster peptides are made by applying peptide molecular biotechnology to the oyster processing process and enzymatically hydrolyzing them. The small molecule oligopeptides formed by this production method completely retain the original vitamins, trace elements, taurine and other nutrients of the oysters, making the oysters rich in nucleic acids more quickly absorbed by the human body than single amino acids or proteins, and more easily absorbed by the body. They have more important biological activity in human metabolism and can effectively increase male serum testosterone levels. They have higher biological value and more important physiological functions than ordinary oyster products.

[0004] Oyster peptides need to be enzymatically hydrolyzed during the production process. However, in the current enzymatic hydrolysis equipment for oyster peptides, the various materials cannot be fully mixed during the process of adding enzymatic hydrolysis powder to the oyster peptides. The materials are more likely to settle to the bottom after mixing, resulting in an incomplete enzymatic hydrolysis process and low enzymatic hydrolysis efficiency. In addition, after the enzymatic hydrolysis of the oyster peptides, the tank is not cleaned in time, and a huge fishy smell will be generated during long-term use, thus affecting the product quality.

[0037] The enzymolysis tank 1 and the tank cover 7 are fixedly connected by bolts and nuts.

[0038] A plurality of stirring rods 19 are evenly distributed on the stirring shaft 10 located inside the inner cylinder 3 .

[0039] A bottom plate 20 is provided at the bottom of the enzymolysis tank 1 ; a plurality of supporting legs 21 are provided at the bottom of the bottom plate 20 .

[0040] The upper spiral blade group 13 includes a plurality of downward-turning spiral blade units; and the inclination angle of each downward-turning spiral blade unit decreases from the upper to the smaller one; in the upper spiral blade group 13, the downward-turning force of the spiral blade units from the upper to the smaller one gradually decreases due to the decreasing inclination.

[0041] The lower spiral blade group 14 includes a plurality of upward spiral blade units; and the inclination angle of each upward spiral blade unit increases from top to bottom; in the lower spiral blade group 14, the spiral blade units from bottom to top have decreasing inclination, and the upward force also gradually decreases from bottom to bottom, so that most of the materials can be concentrated in the middle of the inner tube 3 for stirring. At the same time, the water flow generated by the spiral can dissolve the particulate matter in the liquid more quickly, thereby improving the working efficiency of the enzymatic hydrolysis.

[0042] An electric push rod 22 is arranged upward at the bottom of the enzymolysis tank 1 ; the other end of the electric push rod 22 is connected to the bottom of the moving ring 15 .

[0043] The interior of the moving ring 15 is a hollow structure, and a water spray hole 23 is provided on the outside of the moving ring 15; the moving ring 15 is connected to a water pipe 24, and the other end of the water pipe 24 is connected to an external water source. After the enzymatic hydrolysis is completed, the cleaning liquid can be passed into the water pipe 24, and then during the movement of the moving ring 15, the wall of the inner cylinder 3 is sprayed with water and scraped.

[0044] The outer ends of the upper spiral blade group 13 and the lower spiral blade group 14 are fixedly connected with a scraper 25; one side of the scraper 25 abuts against the inner wall of the inner container 2. The scraper 25 can be provided to clean the side wall of the inner container 2. During the rotation of the spiral blades, the material is easily thrown onto the side wall of the inner container 2. The scraper 25 rotates to scrape the side wall of the inner container 2, thereby improving the cleanliness of the device.

[0045] The following steps are involved:

[0046] (1) Steam the oyster meat at 75-80 degrees for 5-10 minutes to kill bacteria in the oyster meat. After steaming, take out the oyster meat and put it into a grinder to grind it into slurry.

[0047] (2) The slurry is introduced into the inner cylinder 3 from the feed port 8, and the enzyme preparation is added according to the weight of the slurry, and the pH value is adjusted to 5.3-6.5. At the same time, the temperature in the enzymolysis tank 1 is set to 50-60 degrees, and the enzymolysis time is set to 30-40 minutes, and then the enzymolysis is carried out. During the enzymolysis process, the enzymolysis tank 1 is stirred regularly, once every ten minutes, to ensure that the enzyme preparation and the slurry are fully mixed.

[0048] (3) A heat medium is introduced into the interlayer to heat the material inside the enzymolysis tank 1 to a certain temperature, such as 85°C or 95°C, and maintain it for a certain time to ensure that all enzymes are inactivated. Then, when the temperature drops to a suitable temperature, such as 40°C, an enzymolysis solution is obtained.

[0049] (4) Open the discharge valve to discharge the enzymatic solution.

[0050] Working principle: When the motor drives the horizontal plate 11 to rotate, since the horizontal plate 11 is fixedly connected to the inner cylinder 3, the entire inner cylinder 3 is driven to rotate. The rotation of the horizontal plate 11 drives the stirring shaft 10 to rotate. After the stirring shaft 10 rotates, it drives the stirring rod 19 to stir the material inside the inner cylinder 3.

[0051] A variety of enzymes are introduced into the interior of the tank through the feeding port 8. During the rotation of the motor, the spiral blade unit attached to the outer wall of the inner cylinder 3 sinks the discharged materials. When the materials sink to the middle of the inner cylinder 3, the spiral blade unit attached to the middle and lower sections of the outer wall of the inner cylinder 3 lifts the sunken materials. Through the multi-angle spiral blade setting, the materials are mixed and stirred in the middle of the inner cylinder 3, making the enzymatic hydrolysis process more efficient.

[0052] During the enzymatic hydrolysis process, the heat conversion of the medium is realized through the medium water inlet 5 and the medium water outlet 6. Through the design of the thermal insulation interlayer 4, the temperature inside the tank is controlled more evenly, making the enzymatic hydrolysis process more complete.

[0053] By externally driving the electric push rod 22 inside the enzymolysis tank 1, the electric push rod 22 pushes the movable ring 15 fixedly connected at the upper end to move, and the movable ring 15 does not rotate, while the inner cylinder 3 rotates, so that the scraper 16 on the movable ring 15 scrapes the material sticking to the wall of the inner cylinder 3. The contents not described in detail in this specification belong to the prior art known to professionals in this field.

[0054] The above-described embodiments only express the preferred embodiments of the present invention, and the description thereof is relatively specific and detailed, but the present invention is not limited to these embodiments. It should be noted that it is obvious to those skilled in the art. Without departing from the purpose of the present invention, any improvement made shall fall within the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
