(2) feeding: through the feeding device will be vitamin E API materials slowly added to the vacuum single-cone dryer inside, in the feeding process, pay attention to the control of feeding speed and feeding volume, to avoid feeding too fast resulting in uneven accumulation of materials, affecting the drying effect, usually loaded with the amount of control in the container of the effective volume of 30% -80% or so.

(3) vacuum: after closing the feed port, start the vacuum pump, the dryer internal air extraction, so that the drying chamber gradually form a certain degree of vacuum, the general vacuum required to reach 0.01-0.1MPa or so. In a vacuum environment, the boiling point of water or organic solvents in vitamin E API will be significantly reduced, thereby accelerating the drying speed.

(4) Heating and drying: open the heating jacket of the heating medium valve, so that hot water, steam or thermal oil and other heating medium into the jacket, the heat through the container wall transfer to the material. At the same time, start the stirring device, stirring paddle to the appropriate speed spinning generally in 5-20 rpm, so that the material in the drying process is fully turned, increasing the contact area between the material and the heating surface, to ensure that the material is heated uniformly, to avoid localized overheating and agglomeration phenomenon, improve the drying efficiency and quality. Turning.

(5) Drying process monitoring: in the drying process, through the temperature sensor, vacuum sensor and other equipment real-time monitoring of the temperature and vacuum in the dryer, and adjusted according to the preset drying parameters, when the moisture content of the material or solvent residue to meet the required standards, the drying process ends. In this process, the operator needs to pay close attention to the changes in the parameters to ensure the stability and reliability of the drying process.

(6) break the air and discharge: close the heating medium valve and vacuum pump, to be returned to normal pressure inside the dryer, open the discharge port, the dried vitamin E raw materials discharged. Discharge should pay attention to avoid contamination or loss of materials, you can use the appropriate discharge device, such as screw conveyor, etc., the material will be transported to the designated packaging or storage location.

(7) Equipment cleaning and maintenance: After the discharge is completed, the vacuum single cone dryer is cleaned up to remove the residual materials and impurities inside, and then the equipment is checked and maintained to ensure the performance and stability of the equipment when it is used next time.

Vitamin E API Vacuum Single Cone Dryer Performance Features

(1)Large production capacity: large loading capacity, generally up to about 80% of the effective volume of the container, suitable for large-scale production of vitamin E API, improve production efficiency.

(2)High drying efficiency

Large effective heat transfer area: its effective heat transfer area is about 1.7 times of the inner area of the container, which can make the material fully absorb heat and speed up the drying speed.

The material movement is sufficient: the material is lifted up in the spiral in the vessel, and then descends along the main axis in a vortex, and is heated evenly and effectively in this dispersed movement, which improves the uniformity and efficiency of drying.

Optimization of vacuum system: The combination of high vacuum at the head of the machine and high-speed pulse airflow at the bottom of the machine with the same temperature in the same direction can efficiently take away the solvent in the material. At the same time, the design of double-channel vacuum pipe opening prevents vacuum blockage, reduces resistance, improves pumping rate and further accelerates the drying process.

(3)Product quality guarantee

Full-sealed nitrogen-filled production: the drying process is fully sealed and can be filled with nitrogen protection, avoiding material contact with the air, preventing oxidation and deterioration, guaranteeing product quality, but also reducing the cross and pollution, improving the cleanliness and safety level.

Prevent material bonding: the gap between the mixer and the container wall is small, and high finish, can effectively prevent the material bonded to the surface of the wall, to ensure that the material can be fully dry, but also to facilitate the cleaning of the equipment.

(4)Meet the aseptic production requirements: optional online CIP (in-situ cleaning) and SP (in-situ sterilization) and online aseptic sampling and other functions, and the upper and lower processes sealed connection, the entire production process closed production, in line with the new version of the GMP production requirements to meet the new version of the production requirements of vitamin E and other aseptic API API production needs.

(5) strong material adaptability

applicable to a variety of material forms: can adapt to the viscosity, poor heat penetration, easy to roll the ball, easy to clump into a block of material drying, for vitamin E APIs with a certain viscosity of the material can also be well dealt with to protect the heat-sensitive materials: the drying process is carried out at low temperatures, the heat-sensitive, crystalline requirements of the material does not produce damage to the ability to maintain the activity and quality of vitamin E so that the active ingredient is not lost. active ingredients are not lost.
