Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of nervonic acid extraction equipment, and more specifically, to a device for separating and distilling nervonic acid from garlic fruit oil. Background Technology
[0002] Garlic fruit oil is a plant oil extracted from garlic fruit seeds. It has unique nutritional value and industrial uses. Garlic fruit oil is an important source of natural nervonic acid, with a higher content than that of maple seeds. It is beneficial for nerve cell repair and brain health. Nervonic acid can be extracted by distillation.
[0003] In existing technologies, when distilling garlic fruit oil using a distillation kettle, a vacuum pump can be used to create negative pressure inside the kettle, which is then heated. The evaporated material is then condensed using a condenser. Heating the kettle can be achieved by installing heat pipes on a stirrer to heat the material inside, which improves heating efficiency. However, this method has some drawbacks. The heat pipes are typically fixed in position. After the material evaporates, the liquid level drops, exposing some of the heat pipes above the material, thus affecting heating efficiency. Utility Model Content

The fixed heat conductor and the lifting heat conductor are both located inside the distillation kettle, and the lifting heat conductor is located above all the fixed heat conductors. The heat transfer oil circulator allows the heat transfer oil to circulate within the fixed heat conductor and the lifting heat conductor.
[0006] Furthermore, the stirrer includes a servo motor mounted on the upper end of the distillation vessel, a first gear mounted on the rotating end of the servo motor, a first sealed bearing mounted on the upper end of the distillation vessel, a rotating rod through which a rotating rod is mounted, a second gear mounted on the upper end of the rotating rod, the first gear and the second gear meshing, and a plurality of stirring rods mounted on the portion of the rotating rod located inside the distillation vessel.
[0007] Furthermore, the fixed heat conductor includes heating coils fixedly installed on both sides of the rotating rod.
[0008] Furthermore, the lifting heat conductor includes a square connecting block installed on the upper end of the rotating rod, a lifting sleeve is fitted on the outside of the square connecting block, lifting rods are installed on both sides of the lifting sleeve, the lifting rods are hollow rods, a heat-conducting pipe is installed on the lifting rods, and the lower end of the heat-conducting pipe is connected to the inlet end of the heating coil below it through a first flexible pipe.
[0009] Furthermore, the heat transfer oil circulator includes a constant temperature chamber installed on the ground on one side of the distillation kettle. Heat transfer oil is placed inside the constant temperature chamber. A circulation pump is installed on the constant temperature chamber. An oil suction pipe is installed at the inlet end of the circulation pump, extending into the constant temperature chamber. An oil inlet pipe is installed at the outlet end of the circulation pump. A first circular groove is formed at the upper end of the rotating rod. The outlet end of the oil inlet pipe is connected to the upper end of the rotating rod via a first rotating joint. The lower ends of the first circular groove are connected to the inlet ends of the heat transfer pipe via second flexible pipes on both sides. A second sealed bearing is installed at the lower end of the distillation kettle. The lower end of the rotating rod passes through the second sealed bearing and extends below the distillation kettle.

A second rotating joint is installed at the lower end of the rotating rod. A circulation pipe is installed at the lower end of the second rotating joint, with the outlet end of the circulation pipe extending into the upper part of the constant temperature chamber.
[0010] The beneficial effects of this utility model are as follows: By installing a fixed heat conductor inside the distillation vessel, the material at the lower end of the distillation vessel can be heated. As the material in the distillation vessel evaporates, its liquid level will drop. After the liquid level drops, the lifting heat conductor can be moved downward to prevent it from moving above the liquid level, thereby ensuring heating efficiency and preventing waste.

[0015] The distillation process of this device is as follows: Material can be added to the distillation vessel 1 through the feed valve 2, and the distilled material can be removed through the discharge valve 3. A vacuum pump can draw negative pressure into the distillation vessel 1. The heat transfer oil circulator 6 makes the heat transfer oil circulate in the fixed heat transfer device 5 and the lifting heat transfer device 7, thereby heating the material.

[0017] The process of stirring materials by the agitator 4 is as follows: the servo motor 8 is started to rotate, which drives the first gear 9 to rotate. The first gear 9 meshes with the second gear 12, which in turn drives the second gear 12, the rotating rod 11, and the stirring rod 13 to rotate, which facilitates the stirring of materials.
[0018] Refer to the instruction manual appendix Figure 1 The fixed heat conductor 5 includes heating coils 14 fixedly installed on both sides of the rotating rod 11. The heating coils 14 can increase the contact area with the material and extend the flow time of the heat transfer oil in the heating coils 14, thereby improving the heat exchange efficiency.

The outlet end of the oil inlet pipe 23 is connected to the upper end of the rotating rod 11 via a first rotating joint 25. The lower end of the first circular groove 24 has openings on both sides. The second flexible tube 26 is connected to the inlet end of the heat-conducting tube 18. The lower end of the distillation vessel 1 is equipped with a second sealed bearing 27. The lower end of the rotating rod 11 passes through the second sealed bearing 27 and extends to the bottom of the distillation vessel 1.

[0022] The process of the heat transfer oil circulator 6 driving the heat transfer oil flow is as follows: The heat transfer oil can be heated by the constant temperature box 20 and kept at a stable temperature. The circulation pump 21 is started to draw the heat transfer oil in the constant temperature box 20 through the oil suction pipe 22, and then enters the first circular groove 24 through the oil inlet pipe 23. The heat transfer oil in the first circular groove 24 can enter the heat transfer pipe 18 through the second flexible pipe 26. The heat transfer oil in the heat transfer pipe 18 enters the heating coil 14 through the first flexible pipe 19, and then enters the second circular groove 28 through the fixed pipe 29. Then, the heat transfer oil returns to the constant temperature box 20 through the circulation pipe 31, which realizes the circulation flow of the heat transfer oil. The first rotating joint 25 and the second rotating joint 30 facilitate the rotation of the rotating rod 11.
