Soft capsules are a common pharmaceutical dosage form in the field of medicine. Due to their soft shell material, they are called soft capsules. Drying is an important step in the preparation of soft capsules, and in general, drying treatment is required during the preparation of soft capsules to ensure the quality and stability of the drug. At this point, the soft capsule dryer equipment will come in handy. Soft capsule dryer is a new type of drying equipment designed and manufactured specifically for the special characteristics of soft capsules.
The process principle of the soft capsule dryer mainly includes the following aspects:
1. Principles of Air Control
The heating system and motion system in the soft capsule dryer work together to complete the drying task. The heating system heats hot water to a certain temperature through devices such as a heating water tank and heater, and maintains the temperature inside the hot water tank. The high-temperature water vapor in the water tank can be atomized and sprayed into the drying chamber through a sprayer, mixed with air, and dispersed to the upper and lower parts of the drying chamber. A temperature gradient and air flow environment with balanced temperature were formed in the drying chamber, completing the task of drying soft capsules.
2. Principle of Heating System
The heating system in the soft capsule dryer mainly provides the required heat for the soft capsules, thereby quickly evaporating the excess water content in the capsules. Its main components include a water tank, heater, temperature sensor, etc. Among them, the water tank heats the water to a certain temperature through a heater, and the temperature sensor can monitor the temperature of the heated water in real time within the set temperature range. Hot water flows in the conveyor belt and is atomized into water vapor through the drying chamber sprayer.
3. Principles of Motion Systems
The motion system in the soft capsule dryer is mainly responsible for uniformly vibrating the soft capsules in the drying chamber and distributing them evenly in the drying chamber. The motion system mainly includes motors, reducers, and driving devices. Among them, the motor drives the reducer through the driving device, which in turn drives the soft capsule to rotate. The drying chamber track is shock-absorbing and anti shake to achieve a uniform speed standard. During the drying process, the soft capsules move at a constant speed to ensure that their surface receives uniform thermal radiation and air drying.
4. Temperature control principle
The temperature control system in the soft capsule dryer mainly monitors the temperature of the drying chamber in real time through temperature sensors, and automatically adjusts the working status of the heating system through the control system. During the entire process of drying soft capsules, the temperature control system can optimize and control the heating, ventilation, and rotation states to ensure that the soft capsules receive uniform and non excessive heating treatment during the drying process, thereby ensuring the quality and stability of the soft capsules.
