In the pharmaceutical industry, microwave drying, as an emerging drying technology, is attracting more and more attention and application. Here are some reasons why more and more pharmaceutical industries are choosing microwave drying:

1. Fast and uniform drying: Microwave drying uses microwave energy to directly act on the inside of the material and generates heat through internal friction of the molecules, making the drying process faster. Compared with traditional hot air drying, microwave drying can significantly shorten the drying time and achieve a more uniform drying effect.

2. Retain drug activity: The characteristic of microwave drying is that the temperature rises quickly and the drying process can be completed at a lower temperature. This low-temperature drying helps retain the active ingredients of the drug and reduces the decomposition and inactivation of heat-sensitive drugs.

3. Energy consumption and cost saving: Microwave drying has a fast process speed and short drying time, which can save energy and production time. In addition, due to the reduced drying time, the equipment occupancy time can also be reduced and production efficiency can be improved.

4. Product quality control: Microwave drying has good process control performance. The temperature and humidity during the drying process can be controlled by adjusting the microwave power and drying time, thereby achieving precise control of product quality.

5. Environmentally friendly: There is no need to use traditional hot air or steam during the microwave drying process, reducing thermal pollution to the environment and consumption of water resources. In addition, microwave drying can also reduce the emission of waste gas and waste water, which meets the requirements of sustainable development.
