Description

Technical Field

[0001] This utility model relates to the technical field of vegetable oil extraction, specifically to a cold-pressing extraction device for vegetable oil. Background Technology

[0002] Cooking oil is an indispensable condiment in human life. Adding cooking oil during cooking can improve heat conduction efficiency, enhance the color of food, and increase nutritional content. Edible vegetable oils can be produced using cold pressing, which uses immense physical and mechanical pressure to separate the oil from the raw materials, purifying and refining it. Cold pressing reduces the need for high-temperature heating, thus preserving the product's natural nutrients and retaining its original biological activity to the greatest extent.

[0003] An existing cold-pressing device for edible vegetable oil, as disclosed in patent publication number CN202120891889.2, includes a cold-pressing component and a leveling component. The cold-pressing component comprises a base, a support rod, a cold-pressing seat, a first guide tube, a second guide tube, and a pressure plate. The cold-pressing seat has a first through hole axially formed, and the first guide tube is located inside the second guide tube, both fixed to the top of the cold-pressing seat. The leveling component includes a central rod, a rotary motor, leveling rods, a movable plate, a connecting rod, a toothed plate, a transmission gear, and a drive motor. The lower end of the central rod is fixedly connected to the output shaft of the rotary motor, and a connecting groove is formed on both sides of the upper end of the central rod. One end of each of the two leveling rods is rotatably connected to a connecting groove. The movable plate is sleeved on the central rod, and both ends of the connecting rod are hinged to the leveling rods and the movable plate, respectively. The leveling rods can level the raw materials to prevent them from easily piling up, thereby ensuring the oil yield.

[0004] However, this device is inconvenient for subsequent processing after cold pressing and lacks practicality. Summary of the Invention
