Description

Technical Field

[0001] This utility model relates to the field of homogenizer technology, specifically to a heat preservation structure applied to a homogenizer. Background Technology

[0002] Homogenizer insulation is used to ensure that the emulsion maintains a suitable temperature during homogenization, thereby optimizing the breakup of fat globules and maintaining the stability of dairy products. In homogenization operations, the emulsion typically needs to be kept at a certain temperature (such as in pasteurization or ultra-high temperature sterilization processes). Insulation prevents sudden temperature drops from causing fat coagulation or viscosity changes, ensuring uniform dispersion of fat globules and preventing stratification. Simultaneously, stable temperature reduces the adverse effects of mechanical shear forces on milk proteins, ensuring smooth transitions to subsequent sterilization, filling, and other processes, ultimately improving product quality and shelf life.

[0003] In existing homogenizer insulation structures, such as the one disclosed in patent publication number CN215464211U, a homogenizer with a constant temperature device is described. In this homogenizer, the homogenizing tank receives the liquid material, and a drive motor drives a stirring head to mix the liquid material evenly. Simultaneously, a sliding plate moves the heating rod and insulation rod up and down, adjusting their positions within the homogenizing tank to ensure uniform heating and improve homogenization. However, the sliding plate is often fitted onto the outer circumference of the frame, and the heating rod and insulation rod connected to the sliding plate cannot be removed from the homogenizing tank. This results in the heating rod and insulation rod being contaminated by the material in the liquid material for extended periods, making cleaning difficult and leading to bacterial growth that could affect the quality and safety of subsequent liquid materials. Utility Model Content

[0004] The purpose of this invention is to provide a heat preservation structure for homogenizers, in order to solve the problem that existing heating rods and heat preservation rods are inconvenient to clean due to long-term contamination by materials in the liquid, which leads to bacterial growth in the materials and affects the quality and safety of subsequent liquids.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A heat preservation structure for a homogenizer includes a homogenizing cylinder with multiple protruding cylinders inside. A temperature control component is located at the bottom of the homogenizing cylinder, passing through the multiple protruding cylinders in sequence. A heater is located at the bottom of the homogenizing cylinder, and a heating strip is connected to the heater and wrapped around the outer circumference of the homogenizing cylinder. A receiving plate is located at the bottom of the heater and the temperature control component. The temperature control component has a heat-absorbing part that contacts the heating strip. The heater, the heat-absorbing part, and the control terminal of the temperature control component are all connected to an external controller.

[0007] A further technical solution is that the temperature control component includes a liquid circulation pipe and a liquid pump. The liquid pump is located between the receiving plate and the homogenizing cylinder. One side of the liquid pump is connected to one end of the liquid circulation pipe. The liquid circulation pipe passes through multiple protruding cylinders in sequence. The other side of the liquid pump is connected to a liquid tank. The other end of the liquid circulation pipe is connected to the liquid tank. The liquid tank is used to receive external liquid. The heat absorption part is inserted into the top of the liquid tank and contacts the heating strip. The start end of the liquid pump is connected to the controller.

[0008] A further technical solution is that a temperature measuring component is provided on the inner wall of the convex cylinder, the temperature measuring component is sleeved on the liquid circulation pipe, the temperature measuring component is used to measure the temperature of the homogenizing cylinder and the liquid circulation pipe, and the starting end of the temperature measuring component is connected to the controller.

[0009] A further technical solution is that the temperature measuring component includes a first temperature sensor and a second temperature sensor. The first temperature sensor is used to measure the temperature of the homogenizing cylinder, and the second temperature sensor is used to measure the temperature of the liquid circulation pipe. The second temperature sensor is provided with a sleeve fitted onto the outer circumferential surface of the liquid circulation pipe.

[0010] A further technical solution is that the front and rear sidewalls of the kit are provided with fixing stickers, which are in contact with the outer peripheral surface of the liquid circulation pipe.

[0011] A further technical solution is that the liquid tank is equipped with a first solenoid valve, which is connected to the liquid pump and has a connecting pipe on its side. The connecting pipe is equipped with a second solenoid valve. Both the first and second solenoid valves are connected to the controller, and the heat-absorbing part is inserted into the top of the liquid tank.

[0012] A further technical solution is that the heat-absorbing part includes a fixed box, a drive motor, a heat-conducting plate, a gear, and a lifting block. The fixed box is fixed to the top surface of the liquid tank, and the drive motor is provided on its inner wall. The lifting block is provided on the side of the heat-conducting plate. The heat-conducting plate slides up and down on the inner wall of the fixed box. The output end of the drive motor is provided with a gear, which meshes with the lifting block. The drive motor is connected to the controller.

[0013] A further technical solution is that the liquid tank is equipped with a drain valve that extends outside the homogenizing cylinder.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The heating bar is electrically heated by a heater at the bottom of the homogenizing cylinder. The heating bar is wrapped around the outside of the homogenizing cylinder. The temperature control component heats the bottom of the homogenizing cylinder through the convex cylinder, thereby improving the uniform heating effect of the homogenizing cylinder. There is no need to insert the heating rod into the homogenizing cylinder. This solves the technical problem that the existing heating rod and heat preservation rod are inconvenient to clean due to long-term contamination by the material in the liquid, which leads to the growth of bacteria in the material and affects the quality and safety of the subsequent liquid.

[0016] 2. The temperature control component is heated by absorbing the heat from the heating strip in the heat-absorbing part. The residual heat of the heating strip is used to increase the temperature of the temperature control component. There is no need to use an external heating source, which reduces resource utilization and improves environmental protection. Attached Figure Description

[0021] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0022] See Figures 1 to 3 This utility model provides a heat preservation structure for a homogenizer, including a homogenizing cylinder 1, a plurality of protruding cylinders 2 inside the homogenizing cylinder 1, a temperature control component passing through the plurality of protruding cylinders 2 in sequence at the bottom of the homogenizing cylinder 1, a heater 3 at the bottom of the homogenizing cylinder 1, a heating strip 4 connected to the heater 3 and wrapped around the outer circumference of the homogenizing cylinder 1, a receiving plate 5 at the bottom of the heater 3 and the temperature control component, and a heat absorption part of the temperature control component in contact with the heating strip 4. The heater 3, the heat absorption part and the control end of the temperature control component are all connected to an external controller.

[0023] It should be noted that the controller uses an STM32 microcontroller or a SMART200 PLC controller.

[0024] Specifically, the heater 3 is activated by the controller to electrically heat the heating strip 4. The heating strip 4 is wrapped around the outer circumference of the homogenizing cylinder 1, which can heat and keep the liquid in the vertical direction of the homogenizing cylinder 1 warm. At the same time, the temperature control component absorbs the heat from the heating strip 4 through its heat-absorbing part to raise its own temperature. The temperature control component heats the bottom of the homogenizing cylinder 1, and together with the heating strip 4, it can keep the liquid in the homogenizing cylinder 1 warm, thereby improving the uniform heating effect of the homogenizing cylinder 1. There is no need to insert the heating rod into the homogenizing cylinder 1, thus solving the technical problem that the existing heating rods and heat-keeping rods are inconvenient to clean due to long-term contamination by the material in the liquid, which leads to the growth of bacteria in the material and affects the quality and safety of the subsequent liquid.

[0025] In a preferred embodiment, the temperature control assembly includes a liquid circulation pipe 6 and a liquid pump 7. The liquid pump 7 is located between the receiving plate 5 and the homogenizing cylinder 1. One side of the liquid pump 7 is connected to one end of the liquid circulation pipe 6. The liquid circulation pipe 6 passes through multiple protruding cylinders 2 in sequence. The other side of the liquid pump 7 is connected to a liquid tank 11. The other end of the liquid circulation pipe 6 is connected to the liquid tank 11. The liquid tank 11 is used to receive external liquid. A heat-absorbing part is inserted into the top of the liquid tank 11 and contacts the heating strip 4. The start end of the liquid pump 7 is connected to the controller.

[0026] It should be noted that liquids include, but are not limited to, water, acetone, and other liquids.

[0027] Specifically, the liquid pump 7 is activated by the controller. The liquid pump 7 draws heated water from the heat absorption section into the liquid circulation pipe 6 from the liquid tank 11. The water in the liquid circulation pipe 6 and the liquid tank 11 circulates, heating the convex cylinder 2 at the bottom of the homogenizing tank and simultaneously heating the homogenizing cylinder 1. Combined with the heating strip 4, this ensures that the liquid material in the homogenizing cylinder 1 is heated more evenly, improving the heat preservation effect of the liquid material. The water in the liquid tank 11 is supplied externally to maintain a sufficient water supply.

[0028] Optionally, a temperature measuring component is provided on the inner wall of the convex cylinder 2. The temperature measuring component is fitted with a liquid circulation pipe 6. The temperature measuring component is used to measure the temperature of the homogenizing cylinder 1 and the liquid circulation pipe 6. The start end of the temperature measuring component is connected to the controller.

[0029] Specifically, during the heating process of the homogenizing cylinder 1 by the heating strip 4 and the liquid circulation pipe 6, the temperature of the homogenizing cylinder 1 needs to be measured by a temperature measuring component to obtain real-time information on its temperature and ensure smooth production. Simultaneously, the temperature signal is received by the controller and displayed externally for easy monitoring by staff.

[0030] Furthermore, the temperature measuring component includes a first temperature sensor 8 and a second temperature sensor 9. The first temperature sensor 8 is used to measure the temperature of the homogenizing cylinder 1, and the second temperature sensor 9 is used to measure the temperature of the liquid circulation pipe 6. The second temperature sensor 9 is provided with a sleeve fitted on the outer circumferential surface of the liquid circulation pipe 6.

[0031] Specifically, the first temperature sensor 8 is used to detect the temperature of the homogenizing cylinder 1. After being connected to the controller, the temperature is transmitted to an external display for easy monitoring by staff. The second temperature sensor 9 is used to detect the temperature of the liquid circulation pipe 6. This temperature is also transmitted to an external display via the controller, which helps to understand the water temperature and adjust the heat absorption section accordingly.

[0032] Furthermore, the front and rear side walls of the kit are provided with fixing stickers 10, which are in contact with the outer peripheral surface of the liquid circulation pipe 6.

[0033] Specifically, the fixing sticker 10 is used to contact the liquid circulation pipe 6 to fix it and ensure that the liquid circulation pipe 6 works normally.

[0034] Optionally, the liquid tank 11 is provided with a first solenoid valve 12, which is connected to the liquid pump. A through pipe 13 is connected to its side, and a second solenoid valve 14 is provided in the through pipe 13. Both the first solenoid valve 12 and the second solenoid valve 14 are connected to the controller. A heat absorption part is inserted into the top of the liquid tank 11.

[0035] It should be noted that the heat-conducting sheet 17 is made of silicone-based material, which has the characteristic of rapid heating.

[0036] Specifically, when heating is initiated, the controller opens the first solenoid valve 12, causing the liquid pump 7 to draw hot water from the liquid tank 11 through the liquid circulation pipe 6, which then heats the convex cylinder 2. The second solenoid valve 14 is opened to allow external cold water to flow in for subsequent heating. Simultaneously, if the water temperature is too high, the second solenoid valve 14 can be opened to allow cold water to combine with the hot water for cooling.

[0037] Optionally, the heat absorption part includes a fixed box 15, a drive motor 16, a heat-conducting plate 17, a gear 18, and a lifting block 19. The fixed box 15 is fixed to the top surface of the liquid tank 11, and the drive motor 16 is provided on its inner wall. The lifting block 19 is provided on the side of the heat-conducting plate 17. The heat-conducting plate 17 slides up and down on the inner wall of the fixed box 15. The output end of the drive motor 16 is provided with a gear 18, which meshes with the lifting block 19. The drive motor 16 is connected to the controller.

[0038] Specifically, fixing the fixing box 15 to the liquid tank 11 facilitates the stable operation of the drive motor 16, heat-conducting plate 17, gear 18, and lifting block 19. When the water temperature is detected by the second temperature sensor 9, if the heat-conducting plate 17 heats the liquid tank 11 for too long and the water temperature is too high, the controller starts the drive motor 16 to rotate the gear 18. The gear 18 drives the lifting block 19 to descend, which in turn drives the heat-conducting plate 17 to descend, detaching it from the heating strip 4 and preventing it from heating the water. If the water temperature is low, the drive motor 16 drives the lifting block 19, causing the heat-conducting plate 17 to contact the heating strip 4, thereby heating the water in the liquid tank 11.

[0039] Furthermore, the liquid tank 11 is equipped with a drain valve 20 that extends outside the homogenizing cylinder 1.

[0040] Specifically, when not in use, the water in the liquid tank 11 can be released through the drain valve 20.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
