Description

Device and method for removing ethanol from seabuckthorn fruit oil

Technical Field

The invention relates to the technical field of distillation devices, in particular to a device and a method for removing ethanol from seabuckthorn fruit oil.

Background Art

Seabuckthorn is a rare plant that can grow in harsh conditions and contains a variety of active ingredients. It is a common Chinese medicine used by ancient Tibetan and Mongolian doctors to treat diseases. It has the pharmacological effects of removing phlegm and benefiting the lungs, nourishing the stomach and spleen, and promoting blood circulation and curing diseases. Seabuckthorn fruit oil contains carotenoids, vitamin E and a variety of trace elements.

At present, there are several methods for extracting seabuckthorn oil from seabuckthorn pulp, such as supercritical fluid extraction, pectinase method and solvent extraction. Except for solvent extraction, other methods have the disadvantage of low oil extraction efficiency. Solvent extraction requires the use of a distillation device to recover ethanol.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

Please refer to Figures 1 to 8, the present invention provides a technical solution:

Embodiment 1: A device for removing ethanol from seabuckthorn oil, comprising a distillation box 1 and a box cover 2 movably connected to the top of the distillation box 1, a distillation device is arranged inside the distillation box 1, the distillation device comprises a stirring mechanism and a cleaning mechanism, a heating tube 1 3 and a heating tube 2 4 are fixedly connected to the middle and bottom of the outer surface of the distillation box 1 respectively, and a discharge pipe 5 is fixedly connected to the bottom of the side of the distillation box 1.

The stirring mechanism includes a motor 601, a stirring shaft 602, a horizontal stirring plate 603, a vertical stirring frame 604 and a mixing rod 605. A mounting frame 6 is fixedly installed on the top of the distillation box 1. The motor 601 is installed at the top center of the mounting frame 6. The stirring shaft 602 is connected to the output end of the motor 601. The horizontal stirring plate 603 is fixedly connected to the outer surface of the stirring shaft 602. The vertical stirring frame 604 is fixedly connected to the bottom of the horizontal stirring plate 603. The mixing rod 605 is fixedly connected to the outer surface of the stirring shaft 602. The bottom of the stirring shaft 602 is fixedly connected with a stirring rod 606.

The cleaning mechanism includes a slide groove 6051 and a cleaning ring 6052. The slide groove 6051 is opened on the outer surface of the mixing rod 605. The cleaning ring 6052 is slidably connected to the inside of the slide groove 6051 through a limiting slider. The cleaning ring 6052 is in close contact with the outer surface of the mixing rod 605. A cavity is provided inside the mixing rod 605. A centrifugal block 60512 is slidably connected inside the cavity. A fixed magnetic block 60513 is fixedly installed inside the centrifugal block 60512. An elastic rope 60514 is fixedly connected to one end of the centrifugal block 60512 away from the stirring shaft 602. A movable rod 6056 is connected to the center of one end of the mixing rod 605 away from the stirring shaft 602.

The mixing rod 605 has one end away from the stirring shaft 602 and is fixedly connected to a connecting frame 6010 on both sides. The movable rod 6056 has one end away from the mixing rod 605 and is fixedly connected to a magnetic ring 6057. The connecting frame 6010 has one end away from the mixing rod 605 and is fixedly connected to a sliding rod 6058. The outer surface of the sliding rod 6058 is connected to a magnetic sliding ring 6059. One end of the sliding rod 6058 is fixedly connected to a limiting ring 60511. A cleaning brush 60510 is fixedly connected to one side of the magnetic sliding ring 6059. The magnetic ring 6057 and the side of the magnetic sliding ring 6059 that are close to each other repel each other.

During mixing, the rotation of the mixing rod 605 generates centrifugal force, which causes the cleaning ring 6052 to slide inside the chute 6051 toward the end away from the stirring shaft 602, thereby driving the cleaning ring 6052 to clean the surface of the mixing rod 605. After the motor 601 is decelerated, the rotation speed of the mixing rod 605 is reduced, and the cleaning ring 6052 stops sliding. At the same time, the centrifugal force causes the centrifugal block 60512 to slide inside the cavity toward the end away from the stirring shaft 602, and the centrifugal block 60512 squeezes the elastic rope 60512. 514. When the elastic rope 60514 contracts, the centrifugal block 60512 pushes the movable rod 6056 to extend. At this time, the magnetic ring 6057 and the magnetic sliding ring 6059 are close to each other. As the magnetic ring 6057 approaches, the magnetic sliding ring 6059 slides outside the sliding rod 6058, thereby moving away from the mixing rod 605. The magnetic sliding ring 6059 drives the cleaning brush 60510 to approach the inner wall of the distillation box 1, so that the cleaning brush 60510 contacts the inner wall of the distillation box 1, and cleans the inner wall of the distillation box 1 along with the rotation.

A distillation tube 7 is connected to the top of the box cover 2, and the bottom of the distillation tube 7 is connected to the box cover 2 through a fixing frame 702. A retaining frame 701 is fixedly connected to the outer surface of the distillation tube 7. A cooling tube 703 is fixedly connected to the end of the distillation tube 7 away from the box cover 2. A collecting tube 704 is fixedly connected to the bottom of the cooling tube 703. A sampling tube 705 is connected to the inside of the retaining frame 701. A detection port 706 is fixedly connected to the side of the sampling tube 705. A one-way valve is installed inside the sampling tube 705 to only allow steam to flow from the bottom to the top. A condenser 7031 is installed inside the cooling tube 703. A metal cooling plate 7032 is fixedly connected to the outer surface of the cooling tube 703. Coolant is filled between the cooling tube 703 and the condenser 7031.

Part of the ethanol vapor will enter the sampling tube 705 and then liquefy. By opening the detection port 706, the ethanol can be sampled and tested.

After entering the distillation tube 7, the ethanol vapor flows to the inside of the cooling tube 703, flows through the condenser 7031 and is liquefied, and flows out from the collecting tube 704. When passing through the inside of the condenser 7031, it exchanges heat with the coolant, causing the ethanol vapor to quickly liquefy and flow down. The metal cooling plate 7032 has good thermal conductivity and can transfer the heat in the coolant. After contacting with the air, the heat is transferred through the air, which can quickly liquefy the ethanol.

Embodiment 2: A telescopic spring 6053 is fixedly connected to one side of the inner wall of the slide 6051, and a magnetic slider 6054 is fixedly connected to one end of the telescopic spring 6053. A cleaning plate 6055 is fixedly connected to one side of the magnetic slider 6054. In this embodiment, the cleaning plate 6055 is in close contact with the outer surface of the mixing rod 605, and the width between the two sides of the cleaning ring 6052 and the outer surface of the mixing rod 605 is greater than the thickness of the cleaning plate 6055. The cleaning ring 6052 is in close contact with the top and bottom of the outer surface of the mixing rod 605, and the magnetic slider 6054 is close to the fixed magnetic block 60513. The two sides attract each other, and during the movement of the centrifugal block 60512, the fixed magnetic block 60513 is driven to move, thereby attracting the magnetic slider 6054 to move. The magnetic slider 6054 slides inside the slide groove 6051, and then drives the cleaning plate 6055 to clean the outer surface of the mixing rod 605. At the same time, the telescopic spring 6053 is squeezed. After the speed of the motor 601 is reduced, the restoring force of the telescopic spring 6053 itself will push the magnetic slider 6054 to reset, and at the same time, the cleaning plate 6055 will slide in the opposite direction for a distance, so as to further clean the outer surface of the mixing rod 605.

Embodiment three: A baffle 60515 is fixedly connected to one side of the centrifugal block 60512 close to the stirring shaft 602. The baffle 60515 is slidably connected to the inner wall of the cavity. The right side of the baffle 60515 and the inside of the cavity are filled with lubricating oil. During the movement of the centrifugal block 60512, the baffle 60515 will be driven to move. After the baffle 60515 moves, the space for storing the lubricating oil will be changed, so that the centrifugal block 60512 will continuously push the lubricating oil during the movement, and the centrifugal block 60512 moves more smoothly.

Embodiment 4: The outer surface of the slide rod 6058 is provided with a thread, and the magnetic sliding ring 6059 is threadedly connected to the slide rod 6058. When the centrifugal block 60512 pushes the movable rod 6056 to move, the magnetic ring 6057 and the magnetic sliding ring 6059 get close to each other. The magnetic sliding ring 6059 rotates outside the slide rod 6058 as the magnetic ring 6057 approaches, thereby driving the cleaning brush 60510 to rotate and clean the inner wall of the distillation box 1, thereby further improving the cleaning effect and preventing ethanol from remaining on the inner wall of the distillation box 1.

A method for removing ethanol from seabuckthorn fruit oil comprises the following steps:
