Abstract
Description
Technical Field
[0001] This utility model relates to the field of colloid mill technology, specifically to a colloid mill suitable for the production of animal protein. Background Technology
[0002] In animal protein processing, colloid mills are commonly used to emulsify chicken bone paste, pork skin, and other animal materials such as chicken carcasses, fish pieces, and animal organs. These processes require the materials to reach a fine and homogeneous state to ensure the quality and taste of the final product.
[0003] The temperature should be kept low during the grinding and emulsification of animal proteins. Temperature control is crucial during this process. The suitable temperature range is typically between 4 and 8°C. This ensures maximum extraction of salt-soluble proteins while preventing protein coagulation, thus preserving their oil and water retention capabilities. Existing colloid mills generate heat between the grinding blocks during prolonged grinding, and the heat from the drive motor is also easily transferred to the grinding blocks, leading to high grinding block temperatures. This can cause salt-soluble proteins to denature and lose their emulsifying effect.
[0004] To address the aforementioned technical problems, this application proposes a colloid mill suitable for the production of animal protein. Utility Model Content
[0005] I. Technical problems to be solved
[0006] The technical problem this invention aims to solve is that during long-term grinding, heat is generated between the grinding blocks, and the heat from the drive motor is also easily transferred to the grinding blocks, which can easily cause the grinding blocks to become too high.
[0007] II. Technical Solution
[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a colloid mill suitable for animal protein production, including a shell, a support frame installed at the bottom of the shell, no plate at the top of the shell, and a fixed grinding plate one installed on the upper inner side, a feeding pipe installed on the eccentric side of the fixed grinding plate one, a cylindrical fixed grinding plate two installed on the inner wall of the shell below the fixed grinding plate, a rotating grinding block rotatably installed inside the shell, a motor connected to the rotating grinding block installed at the bottom of the shell, a coarse grinding layer on the top of the rotating grinding block that mates with the lower side of the fixed grinding plate, a fine grinding layer on the outer wall of the rotating grinding block that mates with the fixed grinding plate two, and a slurry discharge groove passing through the lower part of the shell and the lower part of the fixed grinding plate two;
[0009] The grinding plate has a cooling water chamber inside, and a cooling water delivery assembly that communicates with the cooling water chamber is installed on the outer shell.
[0010] As an improvement, the cooling water delivery assembly includes an inlet pipe and a drain pipe, which are respectively installed on opposite sides of the outer casing, with the drain pipe being higher than the inlet pipe. A water control valve one and a water control valve two are respectively installed on the inlet pipe and the drain pipe.
[0011] As an improvement, the rotating grinding block has a hollow structure inside, and multiple sets of heat dissipation vents are provided on the lower side wall. Multiple sets of heat dissipation vents are provided on the bottom of the outer shell. The heat dissipation vents and heat dissipation vents overlap and intersect.
[0012] As an improvement, the outer wall of the grinding plate is fixedly connected to the outer shell by multiple sets of bolts.
[0013] As an improvement, the lower edge of the fixed grinding plate contacts the top of the second fixed grinding plate, and the upper edge of the rotating grinding block is chamfered.
[0014] III. Beneficial Effects
[0015] The advantages of this invention compared to the prior art are as follows: The second fixed grinding plate is equipped with a cooling water chamber. Cooling water is continuously supplied to the cooling water chamber through the cooling water conveying component to reduce the temperature of the second fixed grinding plate. The second fixed grinding plate is in contact with the first fixed grinding plate and heat exchange occurs between them, which can cool the first fixed grinding plate. The rotating grinding block has a hollow internal structure and multiple sets of heat dissipation vents are provided on the lower side wall, so that the heat on the rotating grinding block can be well dissipated. This ensures that the animal protein can be kept at a low temperature between the second fixed grinding plate and the rotating grinding block, preventing the salt-soluble protein from denaturing and losing its emulsifying effect.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] Animal protein is subjected to multi-stage grinding, as shown in the attached... Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5 As shown, a colloid mill suitable for animal protein production includes a shell 1. A support frame 2 is installed at the bottom of the shell 1. The top of the shell 1 is plateless, and a fixed grinding plate 3 is installed on the upper inner side. The outer wall of the fixed grinding plate 3 is fixedly connected to the shell 1 by multiple sets of bolts. A cylindrical fixed grinding plate 2 10 is installed on the inner wall of the shell 1, below the fixed grinding plate 3. A rotating grinding block 5 is rotatably installed inside the shell 1. A motor 9 connected to the rotating grinding block 5 is installed at the bottom of the shell 1. When the motor 9 is started, it drives the rotating grinding block 5 to rotate, so that the top of the rotating grinding block 5 and the fixed grinding plate 3, and the side of the rotating grinding block 5 and the fixed grinding plate 2 10 form two-stage grinding. A feeding pipe 4 is installed on the eccentric side of the fixed grinding plate 3. Animal protein material enters the space between the fixed grinding plate 3 and the top of the rotating grinding block 5 through the feeding pipe 4. The rotating grinding block 5 has a coarse grinding layer 6 on its top that mates with the lower side of the fixed grinding plate 3. Coarse grinding is performed by the coarse grinding layer 6 on the top of the rotating grinding block 5 that mates with the lower side of the fixed grinding plate 3. The upper edge of the rotating grinding block 5 is chamfered. After coarse grinding, the material enters between the rotating grinding block 5 and the fixed grinding plate 2 10 along the chamfered upper edge of the rotating grinding block 5. The lower edge of the fixed grinding plate 3 contacts the top of the fixed grinding plate 2 10, and a sealing gasket is installed inside to prevent the material from entering between the lower side of the fixed grinding plate 3 and the top of the fixed grinding plate 2 10. The outer wall of the rotating grinding block 5 has a fine grinding layer 7 that mates with the fixed grinding plate 2 10. Fine grinding is performed by the fine grinding layer 7 on the outer wall of the rotating grinding block 5 that mates with the fixed grinding plate 2 10. A slurry outlet 11 is installed between the lower part of the outer shell 1 and the lower part of the fixed grinding plate 2 10. The finely ground material is squeezed and moved to the slurry outlet 11 and discharged through the slurry outlet 11.
[0025] To prevent the temperature from rising during the grinding of animal protein, which could cause salt-soluble proteins to denature and lose their emulsifying effect, please refer to the attached... Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 6 As shown, the fixed grinding plate 10 has a cooling water chamber 12 inside. The outer shell 1 is equipped with a cooling water conveying assembly that communicates with the cooling water chamber 12. The cooling water conveying assembly includes an inlet pipe 13 and a drain pipe 15. The inlet pipe 13 and the drain pipe 15 are respectively installed on opposite sides of the outer shell 1, and the height of the drain pipe 15 is higher than that of the inlet pipe 13. A water control valve 14 and a water control valve 2 16 are respectively installed on the inlet pipe 13 and the drain pipe 15. Cooling water is continuously conveyed to the cooling water chamber 12 through the inlet pipe 13. The cooling water after heat exchange with the fixed grinding plate 10 is discharged through the drain pipe 15 to ensure that the fixed grinding plate 10 is kept at a low temperature. The water flow rate can be controlled by the water control valve 14 and the water control valve 2 16 to adjust the temperature and cooling rate of the fixed grinding plate 10.
[0026] Since the lower edge of the first grinding plate 3 is in contact with the top of the second grinding plate 10, heat exchange occurs between the first grinding plate 3 and the second grinding plate 10, thereby cooling the first grinding plate 3.
[0027] The rotating grinding block 5 has a hollow structure inside, and multiple sets of heat dissipation vents 8 are provided on the lower side wall. Multiple sets of heat dissipation vents 17 are provided at the bottom of the outer shell 1. The heat dissipation vents 8 and 17 overlap and are staggered. The heat generated by the rotating grinding block 5 during grinding is discharged through the heat dissipation vents 8 and 17, thereby reducing the temperature of the rotating grinding block 5.
