[0001] The present invention relates to the technical field of cold-pressed tea oil, and in particular to a cold-pressed oil device and a method for using the same. Background Art

[0002] Camellia oil is an edible vegetable oil extracted from the mature seeds of the common camellia of the Theaceae family. There are generally two camellia oil extraction processes: the pressing method, which is a method of extracting camellia oil from camellia fruit by physical pressing. It originates from the oil-making method of traditional workshops and is a traditional extraction process; the leaching method, which is a method of extracting camellia oil from camellia fruit using edible-grade solvents based on physical and chemical principles. Since the pressing method can make the color, aroma and taste of camellia oil complete and has the characteristics of retaining various nutrients, the pressing method is more commonly used in the processing process.

[0003] The pressing methods of tea oil are divided into hot pressing and cold pressing. The hot pressing method uses the oil crops to fry and crush before pressing, which can increase the oil yield, but high-temperature pressing can easily cause oxidative polymerization in the tea seed oil, decomposition to produce certain peroxides and harmful substances, destroy the nutrients in the tea oil, and there are many impurities, which affect the appearance, color and internal quality of the tea oil. The cold pressing method is to press the oil crops under a low temperature environment (40℃-50℃), the oil quality is better, and the nutrients and natural fragrance are richer.

[0087] Detecting the temperature of the insulation liquid by monitoring component 4;

[0088] If the temperature detected by the monitoring component 4 is lower than the first preset temperature, the temperature control component 3 heats the insulation liquid to increase the temperature;

After the circulating water pipe 21 discharges the insulation liquid, the outlet water temperature detector 42 detects the temperature of the insulation liquid. When the detected temperature is greater than or equal to 40°C and less than or equal to 45°C, the cooling fan is turned off through the control system, and the heater 322 is turned off at the same time. The insulation liquid discharged from the circulating water pipe 21 flows through the outlet pipe 35, the cooling pipe 331, the heating pipe 321 and the water inlet pipe 34, and then flows back into the circulating water pipe 21; when the detected temperature is greater than or equal to 40°C and less than or equal to 45°C, the cooling fan is turned off through the control system, and the heater 322 is turned off at the same time. The insulation liquid discharged from the circulating water pipe 21 flows through the outlet pipe 35, the cooling pipe 331, the heating pipe 321 and the water inlet pipe 34. When the temperature is greater than 45°C, the cooling fan is turned on by the control system, and the heater 322 is turned off at the same time. The cooling fan continuously blows air to the cooling pipe 331. When the insulation liquid flows through the cooling pipe 331, the temperature decreases, and then flows back into the circulating water pipe 21 through the water inlet pipe 34; when the detected temperature is lower than 40°C, the cooling fan is turned off, and the heater 322 is turned on at the same time. The number of heaters 322 turned on can be adjusted according to actual conditions. When the insulation liquid flows through the heating pipe 321, the temperature rises, and then flows back into the circulating water pipe 21 through the water inlet pipe 34, thereby ensuring that the temperature in the cold pressing device 1 is always maintained between 40-45°C, thereby improving the overall processing efficiency of the cold pressing oil equipment.
