Description

Technical Field

[0001] This utility model relates to the technical field of fish peptide processing equipment, and in particular to a constant temperature stirring device for enzymatic hydrolysis of small molecule fish peptides. Background Technology

[0002] In the enzymatic hydrolysis of small molecule fish peptides, the uniformity of stirring is a key factor affecting the hydrolysis efficiency and product quality. However, the fixed position of the stirring component in traditional enzymatic hydrolysis stirring devices has many drawbacks and is difficult to meet the needs of refined enzymatic hydrolysis processes. Traditional stirring devices often employ a single, fixed stirring paddle structure, whose height and angle cannot be adjusted. When processing different amounts of material, the fixed stirring range cannot adapt to changes in material depth. For example, when processing a small amount of fish peptide solution, the stirring paddle can only act on the upper layer of the material, and the material at the bottom is difficult to be fully stirred, resulting in uneven contact between the enzyme and the substrate. This leads to incomplete enzymatic hydrolysis in some areas, resulting in low product purity and poor efficiency. Some improved devices attempt to adapt to different material amounts by manually adjusting the position of the stirring components, but this method is cumbersome and lacks precision. Manual adjustment requires stopping the machine, which not only interrupts the continuity of the enzymatic hydrolysis reaction, but also requires solving the above problems. Utility Model Content

A moving block 17 is sleeved on the lead screw. The adjusting component facilitates driving the moving block 17 and the moving stirring block 11 to move up and down, realizing the adjustment of the stirring range to adapt to the stirring requirements of different amounts of materials. Two sliding grooves are formed on the moving block 17, and the moving block 17 slides on the guide rods 14 through the sliding grooves. The guide rods 14 facilitate restricting the movement direction of the moving block 17, ensuring that the moving block 17 can only move up and down in a straight line, preventing it from deflecting as the lead screw rotates, and ensuring the stable operation of the moving stirring block 11. The bottom of the two guide rods 14 is fixedly connected to a positioning block 15, and the bottom of the lead screw is rotatably installed on the positioning block 15. The side walls of the moving block 17 are symmetrically and fixedly connected to moving stirring blocks 11.

The soft sleeve 13 facilitates preventing the enzymolysis material from contacting the lead screw to cause contamination or the lead screw from being corroded, and at the same time avoids impurities being involved during the operation of the lead screw, ensuring the normal operation of the adjusting component and extending the service life of the lead screw.

The enzyme inlet pipe 3 facilitates accurately adding enzyme preparations conveniently. The cover plate can effectively prevent external impurities from entering the inner tank 7 to contaminate the reaction system, and can also avoid the leakage of internal steam from affecting the reaction temperature.

[0016] Working principle: When the present utility model is in use, first, each electrical component in this application is respectively connected to the power source body. Then, three supporting feet 1 are welded to the bottom of the outer cylinder 2 at equal intervals, and the entire device is stably erected on the ground, avoiding direct contact between the outer cylinder 2 and the ground to cause wear, and at the same time reserving an operating space for the bottom water outlet pipe 6 and the discharge pipe. The outer cylinder 2 and the inner tank 7 are welded to form a closed heat preservation cavity 10. The inner tank 7 serves as the core container for the enzymatic hydrolysis reaction, carrying the mixed system of fish peptide solution and enzyme preparation. The outer cylinder 2 provides protection for the inner tank 7 and isolates the influence of the external temperature. The two together constitute the basic framework for the constant temperature reaction. Next, hot water and other heat preservation liquids are injected into the heat preservation cavity 10 through the water inlet 9 at the top of the outer cylinder 2. The water inlet pipe connected to the water inlet 9 facilitates rapid liquid replenishment. The water outlet pipe 6 at the bottom of the outer cylinder 2 is communicated with the bottom of the heat preservation cavity 10, and the liquid discharge is controlled by a valve to timely replace the aged heat preservation liquid. The liquid in the heat preservation cavity 10 maintains the temperature stability by its own heat capacity, continuously provides a constant temperature environment for the inner tank 7, and reduces the influence of external temperature fluctuations on the enzyme activity. Then, the liquid injection pipe 8 at the top of the inner tank 7 is connected to external equipment through a flange to achieve batch or continuous injection of raw materials such as fish peptide solution, avoiding pollution and low efficiency caused by manual addition. The enzyme inlet pipe 3 serves as a dedicated channel for the enzyme preparation. The cover plate screwed on its top can prevent impurities from entering or steam leakage, ensuring the accurate addition of the enzyme preparation to the reaction system. The raw materials and the enzyme preparation are preliminarily mixed in the closed inner tank 7 to prepare for the enzymatic hydrolysis reaction. At the same time, the stirring system consists of a stirring motor 4, a rotating shaft 12, stirring paddles and adjusting components. The support 5 provides a stable support for the inverted stirring motor 4, reducing the running vibration. The stirring motor 4 drives the rotating shaft 12 to rotate through a sealed bearing. Multiple stirring paddles on the rotating shaft 12 rotate synchronously to perform basic stirring on the materials. The adjusting components further optimize the stirring effect: The first motor 16 is installed in the mounting block at the bottom of the rotating shaft 12 to drive the rotation of the screw rod. The moving block 17 sleeved on the screw rod moves up and down linearly under the restriction of two guide rods 14. The moving stirring block 11 on the side wall of the moving block 17 moves synchronously with it, expanding the stirring range, especially for the materials at the bottom and the edge of the inner tank 7 to be fully stirred to avoid sedimentation. The soft sleeve 13 wraps the screw rod to prevent material pollution or corrosion of the screw rod and ensure the long-term stable operation of the adjusting components. Finally, the enzymatic hydrolysis reaction proceeds efficiently under the synergistic effect of constant temperature and uniform stirring. After the reaction is completed, the product is discharged through the discharge pipe on the other side at the bottom of the outer cylinder 2.至此小分子鱼肽酶解用恒温搅拌装置的使用结束。
