Technical Field

[0001] This utility model relates to the technical field of edible oil cooling equipment, specifically to a cooling device for edible oil processing. Background Technology

[0002] Edible oil refers to animal or vegetable fats used in food production. It is liquid at room temperature. During the production and processing of edible oil, freshly pressed oil is heated to excessively high temperatures. These high temperatures cause oxidation, producing harmful substances and reducing its quality and safety. Therefore, hot edible oil needs to be cooled before subsequent storage, packaging, and other processing steps. Current technologies typically employ natural cooling or air cooling, which have low heat transfer efficiency and require long cooling times, making it difficult to achieve rapid and uniform cooling and thus failing to meet the production requirements of edible oil.

[0006] Furthermore, the upper and lower parts of the cooling chamber are respectively connected to an inlet pipe and an outlet pipe. The other end of the inlet pipe is connected to a liquid pump, and the other end of the outlet pipe is connected to a liquid tank. The liquid pump is fixed on the top of the liquid tank. The inside of the liquid tank is provided with a suction pipe that communicates with the inlet of the liquid pump. A thermoelectric cooler is installed on the side wall of the liquid tank.

Detailed Implementation

[0015] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0016] like Figure 1-3 As shown, a cooling device for edible oil processing includes a tank body. From top to bottom, the tank body comprises an oil inlet chamber 1, a cooling chamber 2, and an oil storage chamber 3. The oil inlet chamber 1 and the cooling chamber 2 are separated by an upper partition 4, and the cooling chamber 2 and the oil storage chamber 3 are separated by a lower partition 5. The upper partition 4 has several upper through-holes 6, and the lower partition 5 has several lower through-holes 7 corresponding to the upper through-holes 6. The upper through-holes 6 and their corresponding lower through-holes 7 are connected by a guide pipe 8, which guides the edible oil from the oil inlet chamber 1 through the cooling chamber 2 into the oil storage chamber 3. The cooling chamber 2 is filled with coolant, forming an immersion liquid cooling environment to exchange heat and cool the high-temperature edible oil flowing through the guide pipe 8, thereby increasing the contact area between the edible oil and the coolant. Compared to natural cooling or air cooling, this significantly improves heat transfer efficiency, enabling rapid and uniform cooling of high-temperature edible oil, shortening cooling time, and meeting the production needs of edible oil. The top of the oil inlet chamber 1 is connected to an oil inlet pipe 9 for receiving high-temperature edible oil. The side of the oil inlet chamber 1 and the bottom of the oil storage chamber 3 are connected by a circulating oil pipe 10, on which a sanitary pump 11 is fixedly installed, forming a closed-loop circulation circuit, allowing the edible oil to circulate through the interior of the cooling chamber 2 multiple times, improving cooling efficiency. The lower part of the oil storage chamber 3 has a conical structure, which facilitates the concentrated flow of oil to the bottom outlet, reducing dead corner residue during oil discharge or circulation, and improving the discharge rate. Support feet 21 are fixedly connected to the outer wall of the oil storage chamber 3.

[0017] The bottom of the oil storage chamber 3 and the circulating oil pipe 10 are connected by a solenoid three-way valve 12. The bottom of the oil storage chamber 3 is connected to the first valve port of the solenoid three-way valve 12, and the circulating oil pipe 10 is connected to the second valve port of the solenoid three-way valve 12. The third valve port of the solenoid three-way valve 12 is the oil discharge port. By controlling the switching state of the solenoid three-way valve 12, the edible oil in the oil storage chamber 3 can be sent into the circulating oil pipe 10 or directly discharged out of the cooling device.

[0018] The upper and lower parts of the cooling chamber 2 are respectively connected to an inlet pipe 13 and an outlet pipe 14. The other end of the inlet pipe 13 is connected to a liquid pump 15, and the other end of the outlet pipe 14 is connected to a liquid tank 16. The liquid pump 15 is fixed on the top of the liquid tank 16. The inside of the liquid tank 16 is provided with a suction pipe connected to the inlet of the liquid pump 15, which is used to draw coolant from the liquid tank 16 and pressurize it into the cooling chamber 2 to maintain the continuous flow of coolant and enhance the heat exchange effect. A semiconductor refrigeration chip 17 is installed on the side wall of the liquid tank 16. The cold end of the semiconductor refrigeration chip 17 is placed inside the liquid tank 16 for active cooling of the circulating coolant. The hot end of the semiconductor refrigeration chip 17 is placed outside the liquid tank 16 to achieve effective heat dissipation, thereby ensuring that the coolant is always at a low temperature. Several heat dissipation fins 18 are fixedly connected to the hot end of the semiconductor refrigeration chip 17 to improve heat dissipation efficiency.

[0019] A temperature detector 19 is installed on the outer wall of the oil storage chamber 3. The probe of the temperature detector 19 extends into the interior of the oil storage chamber 3 to monitor the temperature changes of the edible oil in real time. A controller 20 is installed on the outer wall of the cooling chamber 2. The controller 20 is equipped with a display screen and operation buttons. The sanitary pump 11, the solenoid three-way valve 12, the liquid pump 15, the semiconductor cooling chip 17, and the temperature detector 19 are all electrically connected to the controller 20. The controller 20 automatically adjusts the start and stop of the sanitary pump, the liquid pump 15, and the semiconductor cooling chip 17 according to the temperature signal of the edible oil collected, so as to realize the intelligent control of the edible oil cooling process. When the temperature of the edible oil reaches the preset threshold, the circulation stops to avoid the edible oil from being over-cooled.

[0020] Working principle: like Figure 1-2 As shown, when the cooling device is in use, a fixed amount of high-temperature edible oil enters the oil inlet chamber 1 through the oil inlet pipe 9. Under the action of gravity, the high-temperature edible oil flows into the guide pipe 8 through the upper through hole 6. When it flows downward through the cooling chamber 2, it exchanges heat with the surrounding coolant and is cooled down. The cooled edible oil flows into the oil storage chamber 3. When the sanitary pump 11 is started, the edible oil in the oil storage chamber 3 is pumped back to the oil inlet chamber 1 through the circulating oil pipe 10 to form a circulating cooling path. During this period, the coolant is driven by the liquid pump 15 and sent from the liquid tank 16 to the upper part of the cooling chamber 2 through the liquid inlet pipe 13. It flows in the cooling chamber by pressure and absorbs heat. After absorbing heat, it returns to the liquid tank 16 through the drain pipe 14. The semiconductor cooling chip 17 in the liquid tank 16 continues to work, transferring heat from the cold end to the hot end and dissipating it into the environment through the heat dissipation fins 18 to keep the coolant at a constant low temperature. When the temperature detector 19 detects that the temperature of the edible oil in the oil storage chamber 3 reaches the preset threshold of the controller 20, the controller 20 issues a command to stop the operation of the sanitary pump 11, the liquid pump 15 and the semiconductor cooling chip 17, and controls the electromagnetic three-way valve 12 to switch to the oil discharge mode, opening the third valve port so that the cooled edible oil is discharged out of the device through the oil discharge port.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
