[0024] The side wall of water tank 1 is fixedly connected with motor 6, the output end of motor 6 is fixedly connected with transmission rod 7, transmission rod 7 penetrates water tank 1 and cooling tank 2 and is rotatably connected with them, the outer wall of transmission rod 7 is fixedly connected with two first stirring blades 8, the first stirring blades 8 can stir cold water in water tank 1, so that the cold water near cooling tank 2 is stirred, and the cooling effect of cooling tank 2 is good, the outer wall of transmission rod 7 is fixedly connected with a plurality of second stirring blades 9, the second stirring blades 9 can stir sunflower seed oil in cooling tank 2 to cool evenly, the first stirring blades 8 are arranged in water tank 1, and the second stirring blades 9 are arranged in cooling tank 2.

[0025] Filter tank 5 is provided with filter screen 10, which can intercept and separate solid wax in sunflower seed oil, recess 11 is formed in the inner wall of filter tank 5, filter screen 10 is inserted into recess 11, which can support filter screen 10 to make it stable, dismounting mechanism is provided on filter screen 10, the dismounting mechanism comprises sealing plate 12 fixedly connected with filter screen 10, C-shaped handle is fixedly connected with the side wall of sealing plate 12, rubber protective sleeve is sleeved with the outer wall of C-shaped handle, which can increase comfort, sealing plate 12 penetrates filter tank 5 and is sealingly arranged, two symmetrically arranged T-shaped latches 13 are slidingly connected with filter tank 5, spring 14 is sleeved with the outer wall of each T-shaped latch 13, and the two ends of each spring 14 are fixedly connected with filter tank 5 and T-shaped latch 13 respectively, two positioning grooves 15 are formed in sealing plate 12, and two T-shaped latches 13 are inserted into corresponding positioning grooves 15, discharge hopper 16 is fixedly communicated with the side wall of filter tank 5, and second solenoid valve is fixedly connected with the outer wall of discharge hopper 16, which can discharge dewaxed sunflower seed oil, water inlet pipe 17 and water outlet pipe 18 are fixedly communicated with the side wall of water tank 1, cold water is injected through water inlet pipe 17, and excess water is discharged through water outlet pipe 18.

[0026] In this invention, the sunflower seed oil is preheated (to approximately 90 degrees Celsius) to liquefy the wax in the oil. The oil is then poured into the cooling tank 2 through the feed hopper 3. Cold water is injected into the water tank 1 through the water inlet pipe 17, while excess water in the tank 1 is discharged through the water outlet pipe 18. The cold water filling the water tank 1 cools the sunflower seed oil in the cooling tank 2 (to a temperature of 30 degrees Celsius, at which point the wax crystals solidify, facilitating subsequent solid-liquid separation). The motor 6 is then started, driving the transmission rod 7, multiple first stirring blades 8, and second stirring blades 9 to rotate via its output. The rotation of the second stirring blades 9 agitates the sunflower seed oil, ensuring even cooling and temperature distribution. The rotation of the first stirring blades 8 agitates the cold water in the water tank 1. Stirring ensures sufficient contact between the cold water and cooling tank 2, resulting in excellent cooling of the sunflower seed oil within. After cooling and allowing it to stand for a period of time, open the first solenoid valve on the connecting pipe 4 to discharge the sunflower seed oil and solid wax into the filter box 5. The filter screen 10 intercepts and filters the solid wax in the sunflower seed oil, while the sunflower seed oil is discharged through the discharge hopper 16, thus removing the wax from the sunflower seed oil. The operator holds the two T-shaped pins 13 and moves them in opposite directions. During this process, the spring 14 is stretched until the T-shaped pins 13 disengage from the positioning groove 15. At this point, the operator holds the C-shaped handle to move the sealing plate 12 and the filter screen 10, disengaging the filter screen 10 from the filter box 5 to remove the intercepted solid wax. The wax is then cleaned, preventing the filter screen 10 from becoming clogged.

[0027] This invention solves the problem in existing dewaxing devices by using a combination of a first stirring blade, a second stirring blade, and a detachable filter screen. This addresses the uneven cooling effect caused by the use of cold water to cool sunflower oil in the prior art. Specifically, the cold water near the sunflower oil is hotter than the water further away, resulting in an uneven temperature distribution. Furthermore, the external sunflower oil near the cold water is colder than the internal sunflower oil, leading to poor cooling efficiency. Additionally, existing dewaxing devices often make it difficult to remove the dewaxed crystals, making operation cumbersome and reducing efficiency.
