[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.
[0023] Example:
[0024] like Figures 1 to 5As shown, this utility model provides a vegetable oil raw material drying device, including a drying tank 11 and a support frame 12. The drying tank 11 is installed on top of the support frame 12. The support frame 12 provides support for the drying tank 11, ensuring the overall stability of the drying device. The drying tank 11 is equipped with a circulation component, including a circulating fan 13. The circulating fan 13 promotes air circulation within the drying tank 11, accelerating heat transfer and moisture evaporation, and improving drying efficiency. The drying tank 11 has an air inlet 14 and an air outlet 15. One end of the air inlet 14 and the air outlet 15 are connected to the drying tank 11, and the other end is connected to a pipe. The circulating fan 13 is installed on the pipe. Through the coordinated arrangement of the air inlet 14, the air outlet 15, the pipe, and the circulating fan 13, air circulation within the drying tank 11 can be achieved, making the temperature and humidity distribution within the drying tank 11 more uniform and ensuring the consistency of vegetable oil raw material drying. The drying tank 11 is also equipped with a stirring assembly and a heating assembly. The heating assembly includes heating elements 27, which are arranged around the inner wall of the drying tank 11. By arranging the heating elements 27 around the inner wall of the drying tank 11, the vegetable oil raw materials inside the drying tank 11 can be heated evenly, ensuring uniform heating of all parts of the raw materials and improving the drying effect. The heating elements 27 can be MCH-150 ceramic heating plates. The stirring assembly is located on one side of the drying tank 11. This overall layout of the stirring assembly on one side of the drying tank 11 makes efficient use of space, facilitates installation and maintenance, and simultaneously stirs the raw materials inside the tank.
[0025] like Figure 2 , 3 As shown, the circulation assembly also includes a filter, which is installed on the top of the drying tank 11. The filter is connected to the air inlet 14 and air outlet 15 on the drying tank 11 via a duct. By connecting the filter to the air inlet 14 and air outlet 15, impurities in the circulating air can be filtered to prevent them from entering the drying tank 11 and contaminating the vegetable oil raw materials, thus ensuring a clean drying environment. Both the air inlet 14 and air outlet 15 are equipped with filter plates to prevent the raw materials from entering the conical cylinder 16 and the circulating fan 13.
[0026] The filter includes a conical cylinder 16, with an inlet pipe 17 and an outlet pipe 18 at the top. An air guide plate 19 is located at the top of the inner part of the conical cylinder 16, which alters the direction of airflow into the cylinder, resulting in a more efficient airflow distribution and improved filtration. A dust hopper 21 is located at the bottom of the conical cylinder 16, collecting filtered impurities for regular cleaning and ensuring continuous filter operation. The inlet pipe 17 connects to the air inlet 14 on the drying tank 11, and the outlet pipe 18 connects to the air outlet 15 on the drying tank 11 via a circulating fan 13, which is mounted on a support frame 12. This connection layout of the inlet pipe 17, outlet pipe 18, circulating fan 13, and various interfaces of the drying tank 11 allows filtered air to smoothly re-enter the drying tank 11 for circulation, ensuring the normal operation of the circulation system.
[0027] like Figure 2 , 5 As shown, the heating assembly also includes a temperature sensor 28 and a temperature controller 29. The temperature controller 29 is mounted on the support frame 12, and the temperature sensor 28 is located inside the drying tank 11. The temperature controller 29 is electrically connected to both the temperature sensor 28 and the heating element 27. Through the electrical connection between the temperature sensor 28, the temperature controller 29, and the heating element 27, the temperature inside the drying tank 11 can be monitored, and the operating state of the heating element 27 can be adjusted according to the set temperature to control the drying temperature. This ensures that the vegetable oil raw materials are dried at a suitable temperature, avoiding any impact on the quality of the raw materials due to abnormal temperatures. The temperature sensor 28 can be a PT100 platinum resistance temperature sensor; the temperature controller 29 can be an AI-518P temperature controller.
[0028] The stirring assembly includes a drive motor 22 and a stirring shaft 23. The drive motor 22 is mounted on one side of the drying tank 11, and the stirring shaft 23 is located inside the drying tank 11. This mounting arrangement allows the drive motor 22 to provide stable power to the stirring shaft 23, causing it to rotate within the drying tank 11. The output shaft of the drive motor 22 passes through the drying tank 11 and connects to one end of the stirring shaft 23. This connection transmits the power of the drive motor 22 to the stirring shaft 23, causing it to rotate within the drying tank 11 and stir the vegetable oil raw material. This promotes full contact between the raw material and hot air, improving drying efficiency.
[0029] like Figure 2 , 4As shown, the stirring shaft 23 is equipped with multiple sets of stirring blades 25, which are arranged circumferentially on the stirring shaft 23. This circumferential arrangement of the stirring blades 25 on the stirring shaft 23 expands the stirring range, making the stirring more uniform and ensuring that the vegetable oil raw materials in all positions within the drying tank 11 are fully stirred. Pulleys 26 are provided at both ends of the stirring blades 25. The drying tank 11 has two sets of sliding grooves 31, and the pulleys 26 are slidably connected to the drying tank 11 through the sliding grooves 31. This slidable connection between the pulleys 26 and the sliding grooves 31 reduces dead zones during stirring, further improving the stirring effect. Multiple sets of through holes 32 are formed on the stirring blades 25. These through holes 32 allow hot air to pass through the stirring blades 25 more effectively, enhancing the contact between the hot air and the vegetable oil raw materials, thus improving drying efficiency and uniformity.
[0030] The drying tank 11 is a horizontal tank. This horizontal design increases the surface area of the vegetable oil raw material within the tank, allowing for greater contact between the material and hot air, thus improving drying efficiency and facilitating feeding and discharging operations. The drying tank 11 has a feed hopper 33 at the top and a discharge port 34 on one side, with a control valve 24 installed on the discharge port 34. The feed hopper 33's placement at the top of the drying tank 11 facilitates the pouring of the vegetable oil raw material into the tank, improving feeding convenience. The discharge port 34's location on one side of the drying tank 11 and the control valve 24's installation on the discharge port 34 allow for easy control of the discharge speed and quantity of the dried vegetable oil raw material, meeting various production needs.
[0031] The specific usage and function of this embodiment are as follows:
[0032] During use, place the support frame 12 in a suitable working area, ensuring its stability. Install the drying tank 11 on top of the support frame 12, which provides support for the drying tank 11, ensuring stable operation of the entire device. Connect the air inlet 14, air outlet 15, and pipes. Install the circulating fan 13 on the pipes and install the filter on top of the drying tank 11, connecting the filter inlet pipe 17 to the air inlet 14 pipe and the exhaust pipe 18 to the air outlet 15 pipe via the circulating fan 13. This series of connections constitutes an air circulation and filtration system, providing clean and circulating air for the drying process. Install the temperature sensor 28 inside the drying tank 11 and the temperature controller 29 on the support frame 12, ensuring they are correctly connected to the heating element 27 to monitor and control the drying temperature. The drive motor 22 is installed on one side of the drying tank 11. The output shaft of the drive motor 22 is passed through the drying tank 11 and connected to the stirring shaft 23. The stirring blade 25 is installed on the stirring shaft 23. The pulleys 26 at both ends of the stirring blade 25 cooperate with the sliding groove 31 in the drying tank 11 so that the stirring assembly can work normally and stir the raw materials in the tank.
[0033] Open the feed hopper 33 and pour the vegetable oil raw material into the drying tank 11 through the feed hopper 33. The feed hopper 33 is located at the top of the drying tank 11 for easy pouring of the raw material, improving feeding convenience. Start the heating element 27. The heating element 27, which surrounds the inner wall of the drying tank 11, begins to work, evenly heating the vegetable oil raw material in the drying tank 11 to ensure uniform heating of all parts of the raw material and provide heat for the drying process. Turn on the drive motor 22, which drives the stirring shaft 23 to rotate. The stirring blades 25 arranged circumferentially on the stirring shaft 23 rotate accordingly, stirring the vegetable oil raw material. The pulleys 26 at both ends of the stirring blades 25 slide within the grooves 31, reducing dead zones in the stirring. The through holes 32 on the stirring blades 25 allow hot air to pass through better, ensuring full contact between the raw material and the hot air, improving drying efficiency and uniformity. The circulating fan 13 is activated, causing air to enter the drying tank 11 through the air inlet 14. Inside the tank, air flows and exchanges heat with the raw materials, carrying moisture out through the air outlet 15 and returning to the air inlet 14 via a pipe, forming a cycle. This results in a more uniform temperature and humidity distribution within the drying tank 11, ensuring consistent drying of the vegetable oil raw materials. During air circulation, air containing impurities enters the conical filter 16. The air guide plate 19 changes the airflow direction, causing impurities to separate under centrifugal force and gravity, falling into the ash hopper 21. The filtered clean air exits through the exhaust pipe 18 and re-enters the drying tank 11 via the circulating fan 13, preventing impurities from contaminating the raw materials and ensuring a clean drying environment. The temperature sensor 28 monitors the temperature inside the drying tank 11 and feeds the data back to the temperature controller 29. The temperature controller 29 automatically adjusts the operating state of the heating element 27 according to the set temperature value, ensuring the drying process is carried out at a suitable temperature and avoiding the impact of abnormal temperature on the quality of the raw materials. After drying, the control valve 24 on the discharge port 34 is opened, and the dried vegetable oil raw material is discharged from the discharge port 34. The discharge port 34 is located on one side of the drying tank 11 and is equipped with the control valve 24 to facilitate control of the discharge speed and discharge volume.
