Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, specifically a cooling device for tea oil production. Background Technology

[0002] In the production of tea oil, the cooling process is a key step to ensure the quality of tea oil. After high-temperature treatment such as extraction and refining, tea oil needs to be cooled to a suitable temperature quickly and evenly to prevent oxidation and rancidity of the oil and loss of nutrients, and to ensure its stable physicochemical properties and excellent flavor quality.

[0003] Currently, common methods for cooling tea oil mainly include jacketed cooling and agitation cooling. Jacketed cooling involves introducing coolant into the container jacket to remove heat from the tea oil through heat conduction. Agitation cooling, on the other hand, promotes heat transfer within the tea oil through mechanical agitation, accelerating heat exchange with the container walls. However, traditional jacketed cooling methods only cool the outer layer of the tea oil. Due to the poor thermal conductivity of tea oil, a significant temperature gradient of "cold outer layer and hot center" forms inside, resulting in uneven cooling and severely affecting the cooling effect and quality of the tea oil. While agitation cooling can promote heat exchange to some extent, relying solely on conduction for heat dissipation is inefficient. Therefore, a cooling device for tea oil production is needed to address the problems existing in current technologies. Utility Model Content

[0004] The purpose of this invention is to provide a cooling device for tea oil production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for tea oil production, comprising a tea oil cylinder and a jacketed cooling cylinder, wherein the jacketed cooling cylinder is sleeved on the outside of the tea oil cylinder, and a jacketed cavity is provided between the tea oil cylinder and the jacketed cooling cylinder. A heat-conducting mechanism is provided inside the tea oil cylinder, the heat-conducting mechanism comprising a hollow stirring rod, a circulating water outlet pipe, and a hollow stirring plate. The hollow stirring rod is rotatably connected to the inside of the tea oil cylinder, the hollow stirring plate is circumferentially fixed to the side surface of the hollow stirring rod, the circulating water outlet pipe is also circumferentially fixed to the side surface of the hollow stirring rod, and an inclined air-cooling pipe is fixed to the side surface of the jacketed cooling cylinder, with a fan fixed to the end of the inclined air-cooling pipe away from the jacketed cooling cylinder.

[0006] Preferably, the hollow stirring plate is connected to the hollow stirring rod, the circulating water outlet pipe is connected to the hollow stirring rod, and the circulating water outlet pipe is located above the hollow stirring plate.

[0007] Preferably, the inner wall of the jacketed cooling cylinder is provided with an annular groove, and one end of the inclined air-cooled pipe is provided with a guide port, which is connected to the annular groove.

[0008] Preferably, the end of the circulating water outlet pipe away from the hollow stirring rod is provided with a water outlet, and the port of the water outlet is aligned with the inner wall of the inclined air-cooling pipe.

[0009] Preferably, a bearing seat is fixed at the bottom center of the jacketed cooling cylinder, a circulating water pump is fixed at the lower end of the bearing seat, one end of the hollow stirring rod extending out of the jacketed cooling cylinder is rotatably connected to the outlet end of the circulating water pump, and a circulating water inlet pipe is fixedly connected between the jacket cavity and the inlet end of the circulating water pump.

[0010] Preferably, a driven wheel is fixed to the upper end of the hollow stirring rod, a drive motor is fixed to the side surface of the jacketed cooling cylinder, the drive motor is fixed to the upper end of the drive motor, and a transmission belt is provided between the driven wheel and the driving wheel.

[0011] This utility model provides a cooling device for tea oil production, which has the following advantages compared with the prior art:

[0012] By using a heat-conducting mechanism, the outer ring of the tea oil is cooled by the coolant in the jacketed cavity. At the same time, the heat in the central area of ​​the tea oil is directly absorbed through the circulation channel composed of hollow stirring rods and hollow stirring plates. The outer layer and the center are cooled at the same time, effectively eliminating the temperature gradient of "cold outer layer and hot center". This changes the inefficient mode of traditional stirring that relies solely on conduction for heat dissipation and significantly improves the overall cooling efficiency.

[0013] Through the installed circulating water outlet pipe, inclined air-cooling pipe and fan, the circulating coolant absorbs heat and is discharged through the circulating water outlet pipe into the inclined air-cooling pipe. The coolant impacts the pipe and splashes, increasing the contact area with the air, which helps to improve fluidity and promote heat dissipation. In conjunction with the operation of the fan at one end of the inclined air-cooling pipe, the heat dissipation is further enhanced. Through the dual methods of splashing and air cooling, the circulating coolant is effectively cooled, maintaining the temperature difference between the tea oil and the coolant, and continuously providing power for the cooling of the tea oil.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a cooling device for tea oil production, including a tea oil cylinder 1 and a jacketed cooling cylinder 2. The jacketed cooling cylinder 2 is sleeved on the outside of the tea oil cylinder 1, and a jacketed cavity 3 is provided between the tea oil cylinder 1 and the jacketed cooling cylinder 2. A heat conduction mechanism 4 is provided inside the tea oil cylinder 1. The heat conduction mechanism 4 includes a hollow stirring rod 5, a circulating water outlet pipe 6, and a hollow stirring plate 7. The hollow stirring rod 5 is rotatably connected to the inside of the tea oil cylinder 1. The hollow stirring plate 7 is circumferentially fixed to the side surface of the hollow stirring rod 5, and the circulating water outlet pipe 6 is also circumferentially fixed to the side surface of the hollow stirring rod 5. The hollow stirring plate 7 is connected to the hollow stirring rod 5, and the circulating water outlet pipe 6 is connected to the hollow stirring rod 5. The circulating water outlet pipe 6 is located above the hollow stirring plate 7 and is filled with coolant. Through the circulation of the coolant, the heat is absorbed from the outer wall of the tea oil cylinder 1, thereby cooling the outer ring of the tea oil. The heat conduction mechanism 4 directly absorbs the heat in the central area of ​​the tea oil through stirring and internal coolant circulation, solving the problem of inefficient heat dissipation by traditional stirring.

[0021] Further as Figure 3 As shown, it is worth noting that an inclined air-cooling pipe 8 is fixed to the side surface of the jacketed cooling cylinder 2. A fan 9 is fixed to the end of the inclined air-cooling pipe 8 away from the jacketed cooling cylinder 2. An annular groove 10 is opened on the inner wall of the jacketed cooling cylinder 2. A guide port 11 is opened at one end of the inclined air-cooling pipe 8. The guide port 11 is connected to the annular groove 10. An outlet 19 is provided at the end of the circulating water pipe 6 away from the hollow stirring rod 5. The port of the outlet 19 is aligned with the inner wall of the inclined air-cooling pipe 8. The outlet 19 is aligned with the inner wall of the inclined air-cooling pipe, so that the coolant impacts the inner wall of the pipe to form a splash, expands the heat dissipation area, and improves the heat dissipation effect. The fan 9 blows air into the inclined air-cooling pipe to accelerate the air flow and forcibly remove the heat dissipated by the coolant, further improving the air-cooling effect.

[0022] Further as Figure 4 As shown, it is worth noting that a bearing seat 17 is fixed at the bottom center of the jacketed cooling cylinder 2, and a circulating water pump 16 is fixed at the lower end of the bearing seat 17. The hollow stirring rod 5 extends out of the jacketed cooling cylinder 2 and is rotatably connected to the water outlet of the circulating water pump 16. A circulating water inlet pipe 18 is fixedly connected between the jacket cavity 3 and the water inlet of the circulating water pump 16.

[0023] Further as Figure 1 As shown, it is worth noting that the upper end of the hollow stirring rod 5 is fixed with a driven wheel 13, the side surface of the jacketed cooling cylinder 2 is fixed with a drive motor 12, the drive motor 12 is fixed at the upper end of the drive motor 12, and a transmission belt 15 is provided between the driven wheel 13 and the driving wheel 14.

[0024] This solution has the following working process: Before use, tea oil is added to the inside of the tea oil cylinder 1, while coolant is added to the jacket cavity 3 between the tea oil cylinder 1 and the jacketed cooling cylinder 2. In this way, the coolant in the jacket cavity 3 flows to cool the outer ring of the tea oil stored in the tea oil cylinder 1. During use, the hollow stirring rod 5 and the hollow stirring plate 7 rotate inside the tea oil cylinder 1 and stir the tea oil to promote heat dissipation. Since the jacket cavity 3, the circulating water inlet pipe 18, the circulating water pump 16, the hollow stirring rod 5 and the hollow stirring plate 7 form a circulation channel, the heat in the central area of ​​the tea oil is directly absorbed during the stirring process, avoiding the inefficient problem of traditional stirring relying solely on conduction for heat dissipation. The simultaneous cooling of the outer layer and the center eliminates the temperature gradient of "cold outer layer and hot center".

[0025] After the circulating coolant absorbs heat, it is discharged through the circulating water outlet pipe 6 towards the inclined air-cooling pipe 8. At this time, the splashing state generated by the coolant impacting the inclined air-cooling pipe 8 helps to improve its fluidity and promote heat dissipation. In addition, the operation of the fan 9 set at one end of the inclined air-cooling pipe 8 can further improve the heat dissipation effect of the coolant. The use of splashing and air cooling can ensure that the circulating coolant is effectively cooled, thereby controlling the temperature difference between the tea oil and the coolant and improving the cooling efficiency of the tea oil.
