This utility model relates to the technical field of mixing and batching devices, specifically a vegetable oil mixing and batching device, including a mixing tank. A support leg is fixedly connected to the lower surface of the mixing tank, and a clearance groove is formed on the lower surface of the mixing tank. An isolation cover is fixedly connected to the inner wall of the clearance groove, and a mixing component is fitted over the isolation cover. This utility model utilizes a first magnet and a second magnet in conjunction. Because the first magnet repels the second magnet, the second magnet can lift the mixing component into the air. Thus, when the mixing component rotates, it will not adhere tightly to the inner wall of the mixing tank under the influence of gravity, resulting in minimal friction between the mixing component and the mixing tank. Therefore, no additional driving force is needed to overcome friction when the mixing component rotates. Furthermore, the absence of friction prevents substances from being rubbed off the mixing component and mixed into the oil, ensuring the quality of the oil.
