As the core equipment in pharmaceutical production, the drying characteristics of vibrating fluidized bed dryer are the basic knowledge that users must deeply understand and master. Only by truly understanding these features can we use the device more effectively, improve its usage and application effectiveness, and avoid mistakes in operation.
The drying rate, as a key indicator to evaluate the drying effect, is affected by a variety of factors. These factors include vibration intensity, air velocity, bed height, air temperature, and particle size.
In the lower vibration frequency range, the drying rate is typically lower than when there is no vibration; In the high-frequency range, the drying rate exceeds the value of no vibration. It is important to note that regardless of the particle size, there is always a minimum value for the drying rate within a given measurement range. The frequency corresponding to this minimum value decreases as the amplitude increases.
In addition, the minimum drying rate is generally found at the vibration intensity of 1, but this can also vary depending on the nature of the material. Therefore, in actual operation, we need to flexibly adjust the vibration intensity, air speed and other parameters according to the characteristics of the material to achieve the best drying effect.
In summary, understanding and mastering the drying characteristics of vibratory fluidized bed dryers is essential to improve the efficiency of equipment use and ensure the quality of pharmaceutical products. We should continue to accumulate experience in daily use, optimize the operation strategy, and ensure that the equipment can give full play to the maximum efficiency.
