Vitamin E API Vacuum Single Cone Dryer Process Flow
(1) Feed preparation: first check the equipment status of the vacuum single-cone dryer to ensure that the equipment is intact, the normal operation of the components, no leakage and other issues. Then the vitamin E API material to be dried ready, generally require the material particle size and moisture content and other indicators in line with the scope of application of the dryer.
(2) Feeding: through the feeding device will vitamin E API materials slowly added to the vacuum single-cone dryer's internal. 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 the amount of loading 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 medium valve of the heating jacket, so that the heating medium such as hot water, steam or heat-conducting oil enters the jacket, and the heat is transferred to the material through the vessel wall. At the same time, start the stirring device, stirring paddle rotating at an appropriate speed, generally 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.
(5) Drying process monitoring: During the drying process, the temperature and vacuum inside the dryer are monitored in real time by temperature sensors, vacuum sensors and other equipment, and adjusted according to the preset drying parameters. When the water content or solvent residue of the material reaches the specified standard, 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 atmospheric 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 a suitable 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 discharging is completed, vacuum single cone dryer is cleaned up to remove the residual materials and impurities inside, and then the equipment is inspected 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 characteristics
(1)Larger 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 accelerate the drying speed.
The material movement is sufficient: the material is lifted up in a spiral in the vessel, and then descends in a vortex along the main axis, 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
Fully sealed nitrogen-filled production: the drying process is fully sealed and can be filled with nitrogen protection, avoiding contact between the material and air, preventing oxidization and deterioration, guaranteeing product quality, and also reducing cross-contamination, improving cleanliness and safety level.
Preventing materials from sticking: the gap between the stirrer and the container wall is small, and the smoothness is high, which can effectively prevent the materials from sticking on the surface of the wall to ensure that the materials can be fully dried, and it is also convenient for the cleaning of the equipment.
(4) Meet the requirements of aseptic production: optional on-line CIP (in-situ cleaning) and SIP (in-situ sterilization) and on-line aseptic sampling and other functions, and the upper and lower processes are sealed and connected, and the entire production process is closed production, in line with the new version of the GMP production requirements to meet the requirements of the new version of GMP production, and can meet the requirements of the production of vitamin E and other aseptic raw materials such as vitamin E APIs.
(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 API such as a certain viscous material can also be well dealt with.
Protection of heat-sensitive materials: the drying process is carried out at low temperatures, the heat-sensitive, crystalline requirements of the material does not produce damage, can maintain the activity and quality of vitamin E, so that its active ingredients are not lost.
(6) Convenient operation and maintenance of equipment
