Description
Technical Field
[0001] The utility model relates to the technical field of vitamin E production, and specifically relates to a vacuum feeding device for producing natural vitamin E. Background Technique
[0002] Natural vitamin E, with α-tocopherol as the main component, is an important fat-soluble antioxidant and is widely used in many fields such as food, health products, and cosmetics. It can not only effectively prevent lipid oxidation, thus extending the shelf life of food, but also help maintain skin health and enhance immune function. Therefore, with the increasing emphasis on a healthy lifestyle by people, the market demand for natural vitamin E is continuously growing.
[0003] Currently, the production of natural vitamin E mainly relies on methods such as plant extraction and chemical synthesis. Among them, the plant extraction method uses natural plant sources (such as vegetable oils, nuts, etc.) to obtain high-purity natural vitamin E. However, in this process, the treatment of raw materials and the control of the extraction process are crucial, especially in terms of the efficiency and safety of the raw material transportation link.
[0004] In the production process of natural vitamin E, the design of the feeding device directly affects the production efficiency and product quality. Traditional feeding devices often face problems such as oxidation risk and temperature rise when transporting raw materials. These factors not only reduce the biological activity of vitamin E but may also lead to a decline in product quality. Therefore, it is particularly important to develop a vacuum feeding device for producing natural vitamin E that can efficiently transport raw materials in a low-oxygen and low-temperature environment.

The opening and closing of the pipes are controlled by the displacement of the movable insert plate 43. It is used to control the opening and closing of the feeding pipe 2 and the discharge pipe 3. When feeding material into the feeding buffer tank 1, the feeding pipe 2 is opened and the discharge pipe 3 is closed. When the natural vitamin E production equipment is working, the raw materials required for the next operation can be fed into the feeding buffer tank 1 first. After the raw materials are fed in, the sealing opening and closing parts 4 close the feeding pipe 2. At the same time, the discharge pipe 3 is also closed, and the feeding buffer tank 1 is vacuumed to prevent the raw materials from oxidizing in the feeding buffer tank 1.

A lead screw 41 is rotatably connected to the left side of the inner wall of the rectangular sleeve 40, which converts the rotation of the motor 42 into the linear motion of the moving insert plate 43. A motor 42 for driving the lead screw 41 to rotate is provided on the left side of the rectangular sleeve 40, which is powered by an external power source.
[0034] Furthermore, a movable insert plate 43 is threadedly connected to the outer wall of the lead screw 41, which opens and closes the pipe through displacement. A rubber sleeve 44 is bonded to the outside of the movable insert plate 43 to enhance the sealing performance. The outer wall of the rubber sleeve 44 of the sealing opening and closing component 4 on the feeding pipe 2 is tightly fitted with the inner wall of the feeding pipe 2, thereby achieving the sealing of the feeding pipe 2. The outer wall of the rubber sleeve 44 of the sealing opening and closing component 4 on the discharge pipe 3 is tightly fitted with the inner wall of the discharge pipe 3, thereby achieving the sealing of the discharge pipe 3.
[0035] Furthermore, the filter housing 60 is provided with a first filter plate 61, a second filter plate 62 and a third filter plate 63 from left to right. The filter hole sizes of the first filter plate 61, the second filter plate 62 and the third filter plate 63 decrease in sequence, and intercept large particles, medium particles and fine impurities in sequence.
[0036] Furthermore, the inner wall of the filter box 60 is provided with three U-shaped positioning grooves 66. The first filter plate 61, the second filter plate 62 and the third filter plate 63 are respectively inserted into the three U-shaped positioning grooves 66 to fix the position of the filter plates.
[0037] Furthermore, a rectangular opening 600 is provided on the front side of the filter box 60 to facilitate the replacement of the filter screen. A cover plate 64 is provided at the rectangular opening 600 to close the maintenance window. A rubber plate 641 is provided on the rear side of the cover plate 64. The outer wall of the rubber plate 641 is tightly fitted with the inner wall of the rectangular opening 600. The front sides of the first filter screen 61, the second filter screen 62 and the third filter screen 63 are all tightly fitted with the rear side of the rubber plate 641 to ensure airtightness.
[0038] Furthermore, mounting holes 640 are provided on the front side of the cover plate 64 near the four corners. Bolts 65 are connected to the mounting holes 640. The bolts 65 are threaded to the front side of the filter box 60 to fasten the cover plate 64 to the filter box 60.
[0039] In this embodiment, the vacuum feeding device for producing natural vitamin E is used by first starting the motor 42 of the sealing opening and closing part 4 to drive the lead screw 41 to rotate, which drives the moving insert plate 43 to exit the inner cavity of the feeding pipe 2 along the clearance opening 8, so that the rubber sleeve 44 releases the seal on the feeding pipe 2. At this time, the sealing opening and closing part 4 of the discharge pipe 3 remains closed, and the raw material is fed into the feeding buffer tank 1 through the feeding pipe 2. After the raw material enters the feeding buffer tank 1, the sealing opening and closing part 4 of the feeding pipe 2 is closed, and at the same time, cooling water is fed into the cooling chamber 10 through the cold water input pipe 11. The water flows through the cooling chamber 10 and is discharged from the water outlet pipe 12, forming a circulation to maintain the low temperature of the raw material in the feeding buffer tank 1. Then, the external vacuum pump is started, and the air path is opened through the solenoid valve on the L-shaped air guide pipe 5 to suck up the feeding material. Air in the buffer tank 1 is filtered through the first filter plate 61, the second filter plate 62, and the third filter plate 63 of the filter element 6 to remove particulate matter in stages, and finally discharged through the vacuum pump extraction pipe 7 to achieve a vacuum environment in the feed buffer tank 1. When discharge is required, the sealing opening and closing part 4 of the discharge pipe 3 is opened, the insert plate 43 is moved out of the inner cavity of the discharge pipe 3, and the raw material is output to the production equipment through the discharge pipe 3. If the filter element 6 needs to be maintained, the bolts 65 on the cover plate 64 can be removed, the cover plate 64 and the rubber plate 641 can be removed, and the first filter plate 61, the second filter plate 62 and the third filter plate 63 can be pulled out from the rectangular opening 600 along the U-shaped positioning groove plate 66 for cleaning or replacement. After completion, the cover plate 64 can be reinstalled and the bolts 65 can be tightened to restore the use.
