Description

Technical Field

[0001] This invention belongs to the field of production technology, specifically relating to a vitamin E preparation production line and its production method. Background Technology

[0002] Vitamin E, or tocopherol, is a fat-soluble vitamin that enhances cellular antioxidant activity, maintains and promotes reproductive function. Clinically, it is mainly used as an adjunct treatment for cardiovascular and cerebrovascular diseases. It can scavenge free radicals in the body, reduce cellular oxygen consumption, promote blood circulation, and participate in some metabolic processes and hormone synthesis. Vitamin E deficiency can cause reproductive disorders, abnormal muscle, liver, bone marrow, and brain function, hemolysis of red blood cells, and embryonic defects. However, high-purity tocopherol is easily oxidized and deteriorates, making it difficult to preserve. Esterification converts it into vitamin E acetate, which is less prone to deterioration and can be broken down into tocopherol after digestion and absorption by humans or animals. Therefore, vitamin E acetate is widely used in food, feed additives, cosmetics, and pharmaceuticals. However, current vitamin E preparation production lines are not continuous enough, have low automation levels, and are inefficient. Summary of the Invention

[0035] A method for producing a vitamin E preparation includes the following steps: Step S1: Vitamin E oil is fed into the first metering tank 200 after being filtered through the feeding oil tank to remove large impurities. The amount of vitamin E oil fed in is obtained by automatic weighing through the first weighing mechanism. Vitamin E oil is fed into the first inlet 110 and filtered through the first filter screen 160 to remove large impurities. When the vitamin E oil is fed quickly, it is directly diverted into the first tank 100 through the first feed pipe 111 and the second feed pipe 112, and then filtered through the second filter screen 190 to ensure the purity of the vitamin E oil entering the first metering tank 200. The first weighing sensor 230 can automatically measure the weight of the first metering tank 200 in real time. The first mounting base plate 240 ensures the stable installation of the first supporting sensor, and the first shim 220 ensures the connection of the first supporting lug 210, which can better adapt to the installation height.

[0036] Step S2: Silica powder is fed into the first silo 300 by the first powder pump 310. The silica powder is fed into the first silo 300 by the first powder pump 310. The first observation tube 320 can be used to check for blockages so as to clear them.

[0037] Step S3: Raw material mixing. The silica powder in the first hopper 300 is fed into the first mixer 400, and the vitamin E oil spray emulsion is also fed into the first mixer 400. The mixture is thoroughly stirred in the first mixer 400. The silica powder and vitamin E oil are fed in proportion. First, the silica powder is fed into the first mixer 400. At the same time, vitamin E oil is sprayed into the first mixer 400 through the first oil supply pipe 450 and the first spray head 431. The first mixer 400 is ventilated and heated to 50-60°C. The first main shaft 410 (its rotation drive method is conventional and will not be described in detail) drives the first plow blade rotor 420 to mix and stir the silica and vitamin E oil until they are evenly mixed. Furthermore, the connection between the first mixer 400 and the second air outlet 480 and the second air inlet 330 not only ensures the air pressure balance within the first mixer 400 and the first hopper 300, facilitating the feeding of silica powder, but also enables dust removal through the first dust bag 340, preventing dust from mixing with the silica powder. Moreover, when air blows onto the first dust bag 340, the flexible structure of the first dust bag 340 can shake and cause the silica powder in the first hopper 300 to vibrate, which can prevent the silica powder from accumulating and clogging.

[0038] Step S4: Air-cooled drying. The mixture obtained in step S3 is fed into the first cooling tank 500. The first vibrating plate 520 slowly sends it to the first separation tank 600. The first blower 510 blows and cools the mixture into the first cooling tank 500. The first vibrating plate 520 (whose vibration drive method is conventional and will not be described in detail) drives the mixture to vibrate and slowly move to the right. The first blower 510 blows cold air into the first cooling tank 500, which can be blown upward through the first air slit 522 to remove moisture from the mixture. The first raised column 521 can also hold the mixture in place by accumulating it over a large area. The mixture falls into the first separation tank 600 on the right side of the first cooling tank 500 and enters the first screening machine 700 through the lower end of the first separation tank 600. The air blown out by the first blower 510 is blown into the first sleeve through the upper end of the first separation tank 600. After being heated by the first heating water pipe 460, it can not only preheat the vitamin E oil, but also heat the cold air before blowing it into the first mixer 400 to provide the required temperature.

[0039] Step S5: Sieving and Storage. The mixture obtained in step S3 is centrifuged in the first sieving machine 700. After sieving and dust removal, it is sent to the first storage tank 720. During centrifugation and sieving in the first sieving machine 700, dust is removed by vacuum adsorption in the first dust removal tank 720, and the remaining vitamin E preparation is collected in the first storage tank 720.

The first vibration plate (520) is provided with a plurality of first raised columns (521), and a first air blowing slit (522) is provided between one side of the first raised column (521) and the first vibration plate (520).

6. The vitamin E preparation production line according to claim 1, characterized in that, The first separation tank (600) has a first air outlet (610) at its upper end, the first mixer (400) has a first air inlet (440) at its upper end, the first air outlet (610) is connected to the first air inlet (440), the first silo (300) has a second air inlet (330) at its upper end, the first mixer (400) has a second air outlet (480) at its upper end, the second air outlet (480) is connected to the second air inlet (330), the first silo (300) has a first dust removal bag (340) inside its upper end, the first dust removal bag (340) and the first silo (300) together form a first dust removal chamber (350), and the second air inlet (330) is correspondingly located inside the first dust removal chamber (350).

7. The vitamin E preparation production line according to claim 6, characterized in that, The first metering tank (200) and the first mixer (400) are connected by a first oil supply pipe (450). A first heating water pipe (460) is wound around the first oil supply pipe (450). A first sleeve (470) is sleeved on the outside of the first oil supply pipe (450). One end of the first sleeve (470) is connected to the first air outlet (610), and the other end of the first sleeve (470) is connected to the first air inlet (440).

8. A method for producing a vitamin E preparation, implemented according to any one of claims 1-7, characterized in that, Includes the following steps: Step S1: Vitamin E oil is fed into the first metering tank (200) after being filtered through the feeding oil tank to remove large impurities. The amount of vitamin E oil fed in is obtained by automatic weighing through the first weighing mechanism. Step S2: Silica powder is fed into the first silo (300) by the first powder pump (310); Step S3: Raw material mixing. The silica powder in the first hopper (300) is fed into the first mixer (400), and the vitamin E oil spray emulsion is also fed into the first mixer (400). The mixture is thoroughly stirred by the first mixer (400). Step S4: Air-cooled drying. The mixture obtained in step S3 is sent into the first cooling tank (500), and the first vibrating plate (520) slowly sends it to the first separation tank (600). The first blower (510) blows and cools the mixture into the first cooling tank (500). Step S5: Screening and storage. The mixture obtained in step S3 is sent to the first screening machine (700) for centrifugation. After screening and dust removal, it is sent to the first storage tank (720).
