Description

Technical Field

[0001] This utility model relates to the field of dairy processing technology, and specifically discloses a multifunctional stirring device for dairy processing. Background Technology

[0002] As an important source of nutrition, dairy products typically involve multiple processing steps, including mixing, stirring, heating, and cooling. The stirring device is one of the core pieces of equipment, used to ensure uniform mixing, promote heat exchange, and improve product texture. During the stirring process, heating the materials according to process requirements is a fundamental operation. For example, precise temperature-controlled stirring of dairy products is required in steps such as pasteurization, fermentation preheating, or sugar dissolution.

[0003] However, existing mixing devices often have limited functionality. On the one hand, many devices lack active and rapid cooling capabilities after mixing and heating, relying solely on natural cooling to reach the temperatures required for subsequent processes. This method is inefficient, prolongs production cycles, and impacts overall efficiency. On the other hand, existing devices typically lack dedicated and convenient sampling mechanisms, making it difficult for operators to take small samples during mixing to observe the mixing state, color, or perform online monitoring.

[0004] Therefore, a multifunctional stirring device for dairy processing is needed to solve the above problems. Utility Model Content

[0005] This invention proposes a multifunctional stirring device for dairy processing, which can actively cool heated materials, improve cooling efficiency, and shorten the production cycle. At the same time, by setting up a dedicated sampling mechanism, it is convenient to extract a small amount of sample during the stirring process for real-time observation and testing.

[0006] This utility model is implemented as follows: a multifunctional stirring device for dairy product processing includes a stirring tank, a tank cover and a tank bottom respectively installed on the upper and lower sides of the stirring tank. A fixing plate is fixedly connected to the outer wall of the stirring tank. A cooling mechanism is provided below the fixing plate. The cooling mechanism includes a flow groove opened in the inner wall of the tank bottom. A heat-conducting plate is fixedly connected inside the flow groove. A water pump is provided below the fixing plate. An inlet pipe is connected between the water outlet end of the water pump and the inside of the flow groove. A water inlet pipe is connected to the water inlet end of the water pump. An outlet pipe connected to the inside of the flow groove is installed on the outer wall of the tank bottom.

[0007] A sampling mechanism is provided on the upper side of the fixed plate. The sampling mechanism includes a sampling dish. An iron plate is fixedly connected to the lower end of the sampling dish. A ring magnet that attracts the lower end of the iron plate is embedded in the upper end of the fixed plate. A positioning ring fitted on the outer wall of the sampling dish is fixedly connected to the upper end of the fixed plate. An L-shaped sampling tube with a manual valve is connected to the outer wall of the stirring tank.

[0008] A heating mechanism is provided above the fixed plate, and a stirring mechanism is provided between the inside and outside of the stirring tank.

[0009] As a preferred embodiment of the multifunctional stirring device for dairy processing according to this utility model, the heating mechanism includes an installation groove formed on the inner wall of the stirring tank, a heat-conducting ring fixedly connected inside the installation groove, a heating sleeve fitted inside the installation groove and conforming to the outer wall of the heat-conducting ring, an insertable temperature sensor extending into the outer wall of the stirring tank, a vertical plate installed at the upper end of the fixing plate, and a temperature controller installed on the outer wall of the vertical plate.

[0010] As a preferred embodiment of the multifunctional stirring device for dairy processing according to this utility model, the stirring mechanism includes a mounting frame installed on the upper end of the can lid, a main shaft that penetrates the can lid is rotatably connected to the top of the inner wall of the mounting frame, a plurality of stirring blades are installed on the outer wall of the main shaft, and a drive motor whose output end is fixedly connected to the main shaft is installed at the upper end of the mounting frame.

[0011] As a preferred embodiment of the multifunctional stirring device for dairy processing according to this utility model, a switch box is installed on the outer wall of the vertical plate.

[0012] As a preferred embodiment of the multifunctional stirring device for dairy processing according to this utility model, the lower end of the tank bottom is connected to a discharge pipe with a manual valve.

[0013] As a preferred embodiment of the multifunctional stirring device for dairy processing according to this utility model, the outer wall of the can lid is connected to a feeding port.

[0014] As a preferred embodiment of the multifunctional stirring device for dairy processing according to this utility model, support frames are installed on both the left and right sides of the lower end face of the fixed plate, and the water pump is installed on the outer wall of the left support frame.

[0015] The beneficial effects of this utility model are:

[0016] 1. During the stirring and heating process, the operator can open the manual valve on the L-shaped sampling tube installed on the outer wall of the mixing tank at any time to allow a small amount of material to flow into the sampling dish. This sampling dish is fixed in place by a ring magnet inside a fixing plate and a bottom iron plate, and its horizontal movement is restricted by a positioning ring to ensure stability when receiving the sample. After sampling, closing the valve allows the sampling dish to be removed for testing. This dedicated sampling mechanism facilitates the convenient extraction of small samples during stirring, providing an effective means for real-time observation and testing.

[0017] 2. After the heating process is completed, if rapid cooling is required, the water pump can be started to pump cold water through the suction pipe and the inlet pipe into the flow channel on the inner wall of the tank bottom. The cooling medium flowing through the flow channel continuously transfers its cooling capacity to the material through the heat-conducting plates fixed in the channel, while the stirring blades continuously agitate the material to enhance heat exchange. The heated cooling medium is finally discharged from the outlet pipe, forming a forced cooling cycle. This design enables the device to actively cool the material after heating, significantly improving cooling efficiency and effectively shortening the production cycle. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0026] Please see Figure 1-5 A multifunctional stirring device for dairy processing includes a stirring tank 1, a tank cover 3 and a tank bottom 2 respectively installed on the upper and lower sides of the stirring tank 1, a fixing plate 17 fixedly connected to the outer wall of the stirring tank 1, a cooling mechanism provided below the fixing plate 17, the cooling mechanism including a flow groove 7 opened in the inner wall of the tank bottom 2, a heat conducting plate 8 fixedly connected inside the flow groove 7, a water pump 9 provided below the fixing plate 17, an inlet pipe 10 connected between the water outlet end of the water pump 9 and the inside of the flow groove 7, a water inlet pipe 11 connected to the water inlet end of the water pump 9, and an outlet pipe 26 connected to the inside of the flow groove 7 installed on the outer wall of the tank bottom 2.

[0027] A sampling mechanism is provided on the upper side of the fixed plate 17. The sampling mechanism includes a sampling dish 19. An iron plate 20 is fixedly connected to the lower end of the sampling dish 19. An annular magnet 18 that attracts the lower end of the iron plate 20 is embedded in the upper end of the fixed plate 17. A positioning ring 21 that is sleeved on the outer wall of the sampling dish 19 is fixedly connected to the upper end of the fixed plate 17. An L-shaped sampling tube 16 with a manual valve is connected to the outer wall of the mixing tank 1.

[0028] A heating mechanism is provided above the fixed plate 17, and a stirring mechanism is provided between the inside and outside of the mixing tank 1.

[0029] In this embodiment: First, the operator injects the dairy raw materials into the mixing tank 1, and stirs the materials in the mixing tank 1 through the stirring mechanism to ensure uniform mixing. During the stirring process, the materials in the mixing tank 1 are heated by the heating mechanism and the temperature is automatically controlled.

[0030] During the mixing process, if it is necessary to check the material status, open the manual valve on the L-shaped sampling tube 16 installed on the outer wall of the mixing tank 1. A small amount of material will flow into the sampling dish 19. During this process, the iron plate 20 at the bottom of the sampling dish 19 and the annular magnet 18 embedded in the upper end of the fixing plate 17 attract each other. At the same time, the positioning ring 21 limits the sampling dish 19, preventing the sampling dish 19 from moving in the horizontal direction and keeping the sampling dish 19 stable. After the sampling is completed, close the manual valve on the L-shaped sampling tube 16. The operator can directly remove the sampling dish 19 from inside the positioning ring 21 to observe and test the sample. By setting up a dedicated sampling mechanism, it is convenient to extract a small amount of sample during the mixing process for real-time observation and testing.

[0031] After the heating process is completed, if rapid cooling is required, the water pump 9 is started. Cold water is drawn through the water pipe 11 and pumped into the flow groove 7 on the inner wall of the tank bottom 2 through the inlet pipe 10. When the cooling medium flows through the flow groove 7, its cooling capacity is transferred to the material through the heat-conducting plate 8 fixed in the groove, and the material is heat-exchanged. The heated cooling medium is finally discharged through the outlet pipe 26. During the cooling process, the stirring blades are needed to stir the material in the stirring tank 1 to keep the material flowing and improve efficiency. This allows for active cooling of the material after heating, improving cooling efficiency and shortening the production cycle.

[0032] As a technical optimization of this utility model, the heating mechanism includes an installation groove 4 opened on the inner wall of the mixing tank 1, a heat-conducting ring 5 fixedly connected inside the installation groove 4, a heating sleeve 6 that fits against the outer wall of the heat-conducting ring 5 inside the installation groove 4, an insertable temperature sensor 25 extending into the outer wall of the mixing tank 1, a vertical plate 23 installed at the upper end of the fixing plate 17, and a temperature controller 22 installed on the outer wall of the vertical plate 23.

[0033] In this embodiment: when heating of the material is required during the stirring process, the heating jacket 6 installed in the installation groove 4 is started to work. The heat is transferred to the inner wall of the mixing tank 1 through the tightly fitted heat-conducting ring 5 to indirectly heat the material. The insertion temperature sensor 25 monitors the material temperature in real time and transmits the signal to the temperature controller 22. The temperature controller 22 precisely adjusts the power of the heating jacket 6 according to the difference between the set value and the measured value, thereby achieving the function of automatic temperature control.

[0034] As a technical optimization of this utility model, the stirring mechanism includes a mounting bracket 13 installed on the upper end of the tank cover 3. A main shaft 14 that penetrates the tank cover 3 is rotatably connected to the top of the inner wall of the mounting bracket 13. Multiple stirring blades are installed on the outer wall of the main shaft 14. A drive motor 15 with its output end fixedly connected to the main shaft 14 is installed at the upper end of the mounting bracket 13.

[0035] In this embodiment: the drive motor 15 is started, and its output end drives the main shaft 14 to rotate, driving the stirring blades fixed on the main shaft 14 to stir the material in the mixing tank 1, ensuring uniform mixing.

[0036] As a technical optimization of this utility model, a switch box 24 is installed on the outer wall of the upright plate 23.

[0037] In this embodiment, the operator can control the on / off state of the drive motor 15, water pump 9, and heating jacket 6 by operating the buttons on the outside of the switch box 24.

[0038] As a technical optimization of this utility model, the lower end of the tank bottom 2 is connected to a discharge pipe 12 with a manual valve.

[0039] In this embodiment: opening the manual valve of the discharge pipe 12 allows the material that has been mixed inside the mixing tank 1 to be discharged.

[0040] As a technical optimization of this utility model, the outer wall of the can lid 3 is connected to a feeding port.

[0041] In this embodiment, the raw materials for dairy products to be processed can be injected into the mixing tank 1 through this feeding port to prepare materials for subsequent processing operations such as mixing and heating.

[0042] As a technical optimization of this utility model, support frames are installed on both the left and right sides of the lower end face of the fixing plate 17, and the water pump 9 is installed on the outer wall of the left support frame.

[0043] In this embodiment: the support frames on the left and right sides together provide stable support for the fixed plate 17 and the components above it, and install the water pump 9.

[0044] The working principle and usage process of this utility model are as follows: First, the operator injects the dairy raw materials into the mixing tank 1 through the feeding port, starts the drive motor 15, and its output end drives the main shaft 14 to rotate, driving the stirring blades fixed on the main shaft 14 to stir the materials in the mixing tank 1 to ensure uniform mixing.

[0045] When heating of the material is required during the mixing process, the heating jacket 6 installed in the installation groove 4 is activated. Heat is transferred to the inner wall of the mixing tank 1 through the tightly fitted heat-conducting ring 5 to indirectly heat the material. The insertion temperature sensor 25 monitors the material temperature in real time and transmits the signal to the temperature controller 22. The temperature controller 22 precisely adjusts the power of the heating jacket 6 according to the difference between the set value and the measured value, thereby achieving the function of automatic temperature control.

[0046] During the mixing process, if it is necessary to check the material status, open the manual valve on the L-shaped sampling tube 16 installed on the outer wall of the mixing tank 1. A small amount of material will flow into the sampling dish 19. During this process, the iron plate 20 at the bottom of the sampling dish 19 and the annular magnet 18 embedded in the upper end of the fixing plate 17 attract each other. At the same time, the positioning ring 21 limits the sampling dish 19, preventing the sampling dish 19 from moving in the horizontal direction and keeping the sampling dish 19 stable. After the sampling is completed, close the manual valve on the L-shaped sampling tube 16. The operator can directly remove the sampling dish 19 from inside the positioning ring 21 to observe and test the sample. By setting up a dedicated sampling mechanism, it is convenient to extract a small amount of sample during the mixing process for real-time observation and testing.

[0047] After the heating process is completed, if rapid cooling is required, the water pump 9 is started. Cold water is drawn through the water pipe 11 and pumped into the flow groove 7 on the inner wall of the tank bottom 2 through the inlet pipe 10. When the cooling medium flows through the flow groove 7, its cooling capacity is transferred to the material through the heat-conducting plate 8 fixed in the groove, and the material is heat-exchanged. The heated cooling medium is finally discharged through the outlet pipe 26. During the cooling process, the stirring blades are needed to stir the material in the stirring tank 1 to keep the material flowing and improve efficiency. This allows for active cooling of the material after heating, improving cooling efficiency and shortening the production cycle.

[0048] Finally, once processing is complete, open the manual valve on the discharge pipe 12 at the bottom of the tank 2 to discharge the finished product.
