Description

Technical Field

[0001] The present invention relates to the technical field of rectification, and particularly to a distillation device and process for producing unsaponifiable matter of corn oil. Background Art

[0002] During the production of corn oil, saponification treatment needs to be carried out on the corn oil. There are still some substances such as sterols, higher alcohols, hydrocarbons, pigments, and fat-soluble vitamins that are insoluble in water but soluble in organic solvents. These substances are collectively referred to as unsaponifiable matter. In order to ensure the quality of corn oil, distillation treatment needs to be carried out on the corn oil to reduce the amount of unsaponifiable matter therein. However, the existing rectification devices still have the following problems:

[0003] The existing distillation device usually heats the corn oil and then, taking advantage of the different boiling points of the unsaponifiable matter and the corn oil, vaporizes the unsaponifiable matter and then condenses it through a serpentine tube. However, in the prior art, the heating of the corn oil usually just directly places an electric hot plate at the bottom of the device, so that at the beginning, the whole corn oil cannot be heated quickly and evenly, affecting the distillation efficiency of the unsaponifiable matter. At the same time, when the vaporized unsaponifiable matter flows in the serpentine tube, it may be due to uneven heat dissipation in the vaporized unsaponifiable matter, resulting in some vaporized unsaponifiable matter in the discharged gas, affecting the collection efficiency of the unsaponifiable matter, and part of the liquefied unsaponifiable matter will adhere to the inner wall of the serpentine tube and is not easy to clean. Therefore, how to reasonably solve this problem is what we need to consider. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art and propose a distillation device and process for producing unsaponifiable matter of corn oil. By using this process, the whole corn oil can be heated quickly and evenly, and at the same time, the vaporized unsaponifiable matter in the serpentine tube can be quickly liquefied, improving the collection efficiency of the unsaponifiable matter. Moreover, the inside of the serpentine tube can be cleaned by a suction pump, and at the same time, high-temperature air flow is used to make the unsaponifiable matter quickly dissolve in the organic solvent, improving the cleaning effect on the inner wall of the serpentine tube.

[0033] The present invention also provides a distillation process for producing corn oil unsaponifiable matter, including the following steps:

[0034] S1: Add corn oil into the box body 1 through the addition port, drive the drive motor 5, the two electric heating rods 2 and the blower 14, so as to vaporize the unsaponifiable matter in the corn oil and inhale it into the serpentine tube 10;

[0035] S2: The operation of the drive motor 5 causes the two hollow plates 15 to rotate, and at the same time the piston 25 moves up and down, so that the normal-temperature air flow blows evenly onto the serpentine tube 10, so that the vaporized unsaponifiable matter can be liquefied and enter the collection box 13;

[0036] S3: When it is necessary to clean the inside of the serpentine tube 10, turn on the control switch to make the liquid injection pipe 11 conduct, the air inlet end of the serpentine tube 10 close, at the same time the liquid discharge port 29 is communicated with the through port 30, and at the same time the blanking port 31 is sealed. When the control switch is turned on, the two electric heating plates 21 are powered on, so that the hot air flow blows onto the serpentine tube 10;

[0037] S4: Start the suction pump 12, pump the organic solution into the serpentine tube 10, so that the unsaponifiable matter adhered to the serpentine tube 10 is dissolved in the organic solvent, and at the same time heat the serpentine tube 10 to accelerate the dissolution of the unsaponifiable matter.

[0038] The functional principle of the present invention can be explained through the following operation mode: corn oil is added into the bottom space of the box body 1 through the adding port, and the two electric heating rods 2, the driving motor 5, and the fan 14 are started. The operation of the driving motor 5 drives the two rotating rods 4 to rotate, thereby rotating the two electric heating rods 2 and the two hollow plates 15. The rotation of the two electric heating rods 2 allows the corn oil to be quickly and evenly heated, so that the unsaponifiable matter in the corn oil can be quickly gasified;

[0039] The operation of the fan 14 will form a gas flow from the outside to the box 1, the serpentine tube 10, the collection box 13, and the outside, thereby quickly sucking the gasified unsaponifiable matter into the serpentine tube 10;

[0040] During the rotation of the two rotating rods 4, the cam 24 will be driven to rotate. Under the elastic action of the first spring 17, the piston 25 and the cam 24 will always be in a state of abutment, so that the rotation of the cam 24 will cause the piston 25 to move up and down continuously. The downward movement of the piston 25 will suck the gas in the box body 1 into the top space of the vertical box 16 through the rectangular box 20. The upward movement of the piston 25 will press the gas in the top space of the vertical box 16 into the two hollow plates 15 and then spray it out through multiple air jets 36, thereby accelerating the gas flow around the serpentine tube 10, so that the gasified unsaponifiable matter in the serpentine tube 10 can dissipate heat evenly, so that the unsaponifiable matter in the airflow can be completely liquefied and enter the collecting box 13 with the airflow. Due to the large weight of the liquefied unsaponifiable matter, it will fall on the inclined plate 32 and then slide through the blanking port 31 to the bottom space of the collecting box 13;

[0041] After the corn oil is distilled, the inside of the serpentine tube 10 needs to be cleaned. At this time, the solenoid valve at the air inlet end of the serpentine tube 10 and the solenoid valve on the injection tube 11 can be energized to make the injection tube 11 conductive, while the air inlet end of the serpentine tube 10 is closed, and then the suction pump 12 is started to inject the organic solvent into the serpentine tube 10, so that the unsaponifiable matter adhering to the inner wall of the serpentine tube 10 can be dissolved in the organic solvent;

[0042] During the operation of the suction pump 12, the two electric heating plates 21 and the electromagnet are both powered on. Since the drive motor 5 is still in operation, gas is still sprayed onto the serpentine tube 10. Due to the arrangement of the two electric heating plates 21, the temperature of the air flow sprayed onto the serpentine tube 10 is increased, so that the unsaponifiable matter can be better dissolved in the organic solvent.

[0043] The organic solvent flowing in the coiled pipe 10 will enter the collection box 13. Since the electromagnet generates a repulsive force on the blocking block 28 after being energized, the blocking block 28 will move downward, the through port 30 will conduct the liquid discharge port 29, and at the same time, the downward movement of the blocking block 28 will cause the gas in the bottom space of the moving cavity 26 to be pressed into the left side of the sliding groove 33, causing the rectangular block 34 to move to the right to seal the material falling port 31, so that the organic solvent entering the collection box 13 can be quickly discharged to the outside.

[0044] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
