Description

Technical Field

[0001] The invention belongs to the technical field of collagen hydrolysis, in particular to a selenium-rich protein peptide enzymatic hydrolysis device. Background Art

[0002] Collagen peptide enzymatic hydrolysis is actually the hydrolysis of protein. The existing protein decomposition methods are chemical method and enzymatic method. Since the reaction process of the chemical method is relatively strong, the amino acids are destroyed during the reaction process, and the reaction equipment is highly corrosive, which reduces the service life of the reaction equipment. The enzymatic hydrolysis has many advantages such as low reaction temperature, short reaction time, no environmental pollution, and high nutritional value of the product. Since protein drinks produced by enzymatic hydrolysis have a better taste, companies often use collagen peptide enzymatic hydrolysis equipment for operations when producing and processing food.

[0003] The protein solution needs to be properly stirred during the enzymatic hydrolysis process so that the internal protein can fully contact with the enzyme and then decompose. However, direct stirring is prone to over-violent beating of the protein solution, which will cause protein flocculation, reduce the protein's expansion and foam stability, and cause protein denaturation and easy precipitation, making it difficult to carry out the enzymatic hydrolysis process, so it needs to be improved.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1.

[0015] 2. When the device controls the movement of the conical flask, the limiting sleeve box at the top will stably clamp the top of the conical flask through the arc-shaped clamping plate on the inner wall of the large sleeve interface, so that there will be no gap between the conical flask and the large sleeve interface, avoiding the problem of the long box shell contacting and colliding with the top of the conical flask during movement, thereby crushing the conical flask. Under the premise of ensuring that conical flasks of different calibers can be stably clamped, the effect of stably clamping the conical flask can be achieved, preventing the conical flask and the long box shell from shaking relative to each other.

[0016] 3. When the conical flask slides, its bottom will slide relative to the load-bearing bottom plate through the rotating ball. The rolling of the rotating ball reduces the friction resistance on the bottom of the conical flask, so that the long box shell can easily drive the conical flask to move, avoiding the problem of easy wear on the bottom of the conical flask. During the oscillation of the conical flask, the solution inside the bottle will not be sprayed to the outside due to the sealing effect of the top folding tube, and the enzyme solution inside the conical flask can be supplemented through the folding tube, and the adaptability can be adjusted for protein solutions of different capacities, thereby improving the practicality of the device.

[0017] 4. The circuit board controls the heating resistor to heat up through the adapter wires on both sides, thereby directly heating the water inside the insulation box shell, so that the water temperature reaches the optimal activity temperature of the decomposition enzyme, so that the decomposition enzyme maintains good activity, thereby quickly performing enzymatic hydrolysis. The temperature measuring component above can only measure the temperature of the internal environment of the insulation box shell by absorbing heat energy and inhaling air when the conical flask is undergoing the oscillation process, and then perform temperature adjustment work in time, thereby reducing the interference of external environmental temperature and avoiding the problem of reduced enzyme solution activity.

Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0028] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a selenium-rich protein peptide enzymatic hydrolysis device, comprising a material injection device 2 and an insulated box shell 1, a traction component 3 is arranged on the top of the insulated box shell 1, and an auxiliary bottom plate 4 is arranged on the bottom of the inner wall of the insulated box shell 1;

[0029] The material injection device 2 includes a material distribution top shell 21, the upper surface of which is fixedly connected to the ceiling through a fixed connecting rod 22, and the bottom of the inner cavity of the material distribution top shell 21 is evenly provided with folding tubes 23, and the bottom end of the inner wall of the folding tube 23 is sleeved with a conical bottle 24, and the material distribution top shell 21 can add an appropriate amount of enzyme to the inside of each conical bottle 24 through the hollow folding tube 23;

[0030] The traction component 3 includes a clustering pull plate 31, the inner cavity of the clustering pull plate 31 is evenly provided with a limit sleeve 5, and vertical traction rods 32 are symmetrically provided on the front and rear sides of the upper surface of the clustering pull plate 31. The top of the vertical traction rod 32 is fixedly connected with a bent connecting plate 33, and the bottom of the bent connecting plate 33 is fixedly connected with a segmented pull plate 34. The segmented pull plate 34 can pull the bent connecting plate 33 through the tension plates on both sides to slide synchronously, and the bent connecting plate 33 can slide stably along the slide grooves on the front and rear sides of the upper surface of the insulation box shell 1;

[0031] The limiting sleeve 5 includes a long box shell 51, the inner cavity of the long box shell 51 is evenly provided with large sleeve ports 52, the inner diameter of the large sleeve ports 52 is larger than the outer diameter of the end of the conical flask 24, to ensure that the top of the conical flask 24 can pass through the long box shell 51, arc-shaped clamping plates 53 are symmetrically arranged on both sides of the inner wall of the large sleeve port 52, a thrust connecting rod 55 is fixedly connected to the middle of the outer surface of the arc-shaped clamping plate 53, and a controller 54 is slidably connected to one end of the thrust connecting rod 55 away from the arc-shaped clamping plate 53, and the controller 54 can push the arc-shaped clamping plates 53 on both sides through the thrust connecting rod 55.

[0032] There are four bent connecting plates 33, the top of the inner wall of the bent connecting plate 33 is slidably connected to the upper surface of the heat preservation box shell 1, there are three limit sleeves 5, the outer surface of the long box shell 51 is fixedly connected to the inner cavity of the cluster pull plate 31, and the top of the outer surface of the conical bottle 24 passes through the large sleeve interface 52. The outer surface of the thrust connecting rod 55 is slidably connected to the inner wall of the large sleeve interface 52 through the through hole, the front and rear sides of the outer surface of the controller 54 are fixedly connected to the inner wall of the long box shell 51 through the fixing rod, and the inner wall of the arc clamping plate 53 and the top of the outer surface of the conical bottle 24 are pressed against each other.

[0033] When the device is used to perform an enzymatic hydrolysis process on a conical flask 24 solution containing a protein peptide, each conical flask 24 is evenly placed inside the incubator shell 1, and then the traction component 3 is buckled on the upper surface of the incubator shell 1 so that the top of the conical flask 24 can pass through the large sleeve 52, and then the upper folding tube 23 is pulled down and inserted into the corresponding port of the conical flask 24, as shown in FIG. Figure 2 As shown, the preparation work is completed.

[0034] Since the large socket 52 has a larger flare, after the top end of the conical flask 24 passes through the large socket 52, the controller 54 located inside will push the thrust connecting rod 55 to slide the arc clamping plate 53 toward the outer surface of the end of the conical flask 24, so that the arc clamping plates 53 on both sides can clamp and limit the end position of the conical flask 24, thereby reducing the gap between the conical flask 24 and the large socket 52.

[0035] During operation, the segmented pull plates 34 on both sides pull the bent connecting plates 33 to slide synchronously, so that the cluster pull plates 31 slide back and forth along the upper part of the inner wall of the thermal insulation box shell 1, thereby driving all the conical flasks 24 to move, and then oscillating the protein solution inside. At this time, a solution containing a degrading enzyme is added to the interior of the conical flask 24 through the folding tube 23 on the top, and mixed with the protein solution to oscillate. Since the folding tube 23 can undergo elastic deformation with the movement of the conical flask 24, it can achieve stable transportation of the enzyme solution.

[0036] Example 2, please refer to Figure 1-Figure 8The present invention provides a technical solution: on the basis of the first embodiment, the auxiliary bottom plate 4 includes a load-bearing bottom plate 41, and the upper surface of the load-bearing bottom plate 41 is evenly provided with rotating balls 42 through the embedded grooves, and the rotating balls 42 can roll freely. The bottom of the inner wall of the load-bearing bottom plate 41 is fixedly connected with a circuit board 43, and the left and right sides of the outer surface of the circuit board 43 are symmetrically provided with switching wires 44, and the top of the switching wires 44 is fixedly connected with a heating resistor 45. The circuit board 43 can heat the water inside the heat preservation box shell 1 by heating the heating resistor 45 through the switching wires 44. There are two heating resistors 45, and the top of the heating resistor 45 extends to the upper part of the load-bearing bottom plate 41, and the outer surface of the heating resistor 45 is fixedly connected to the top of the inner cavity of the load-bearing bottom plate 41, and the bottom of the conical bottle 24 and the outer surface of the rotating ball 42 are pressed against each other.

[0037] Water injection grooves 12 are symmetrically opened on the left and right sides of the inner cavity of the insulation box shell 1, and drainage openings 11 are symmetrically opened on the front and back sides of the bottom of the inner cavity of the insulation box shell 1. The bottom of the inner wall of the insulation box shell 1 is fixedly connected to the outer surface of the load-bearing bottom plate 41, and temperature measuring components 6 are symmetrically arranged on the front and back sides of the upper part of the inner wall of the insulation box shell 1, and the top of the heating resistor 45 extends to the interior of the insulation box shell 1.

[0038] The temperature measuring component 6 includes a long plate 61 attached to the wall, and transfer balls 62 are evenly arranged on one side of the inner cavity of the long plate 61 close to the clustering pull plate 31. A two-way slide plate 63 is slidably connected to the inner wall of the long plate 61 close to the transfer balls 62 through a slide groove. When the transfer balls 62 roll, the rolling friction force can be used to control the sliding of the internal two-way slide plate 63. A thermometer 64 is fixedly connected to one side of the inner wall of the long plate 61 away from the transfer balls 62.

[0039] The left and right sides of the inner cavity of the wall-attached long plate 61 are rotatably connected with a one-way fan plate 65 through a groove. The one-way fan plate 65 can only rotate toward the outside of the wall-attached long plate 61, and cannot rotate toward the inside of the wall-attached long plate 61. The outer surface of the one-way fan plate 65 is fixedly connected with an arc spring belt 66, and the end of the arc spring belt 66 away from the one-way fan plate 65 is fixedly connected to the inner wall of the heat preservation box shell 1, and the inner wall of the one-way fan plate 65 and one side of the two-way slide plate 63 are pressed against each other. There are two temperature measuring components 6, the outer surface of the wall-attached long plate 61 is fixedly connected to the inner wall of the heat preservation box shell 1, the outer surface of the cluster pull plate 31 and the outer surface of the transfer ball 62 are pressed against each other, and the outer surface of the transfer ball 62 is rollingly connected to the inner cavity of the wall-attached long plate 61.

[0040] When the conical flask 24 slides left and right, the bottom of the conical flask 24 will roll relative to the outer surface of the rotating ball 42, thereby reducing the friction resistance at the bottom of the conical flask 24 when it moves. The circuit board 43 controls the heating resistor 45 to heat up through the adapter wires 44 on both sides, thereby directly heating the water inside the insulation box shell 1, so that the water temperature reaches the optimal activity temperature of the decomposition enzyme, so that the decomposition enzyme maintains good activity, thereby quickly performing enzymatic hydrolysis.

[0041] The water added from the water injection groove 12 will fill the area where the main body of the conical flask 24 is located. After the enzymatic hydrolysis of each batch of protein solution inside the conical flask 24 is completed, the conical flask 24 is taken out and the waste water is directly discharged through the opened drainage port 11 without being recycled, thereby ensuring that the inside of the container will not be contaminated due to leakage of protein solution or enzyme solution.

[0042] When the clustering pull plate 31 slides left and right, the side of the clustering pull plate 31 will drive the transfer ball 62 in the inner cavity of the wall-attached long plate 61 to roll synchronously through the rolling friction force. At this time, the two-way slide plate 63 on the other side of the transfer ball 62 will slide in the opposite direction of the clustering pull plate 31 under the action of the rolling friction force, thereby pushing the one-way fan plate 65 at the corresponding position to rotate toward the outside of the wall-attached long plate 61, and the arc spring belt 66 is compressed, and the opening here is opened. Because the one-way fan plate 65 will bring the gas inside the insulation box shell 1 into the interior of the wall-attached long plate 61 during the rebound process, the temperature of the gas is measured by the internal thermometer 64.

[0043] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
