Abstract

The invention relates to a drying method of a steroid compound solid material. The steroid compound solid material can be quickly and efficiently dried in an energy-saving manner through a microwave mode, and surprisingly, related impurities are better controlled in the method of the invention compared with a traditional drying mode.

Description

Technical field: [0001] The invention relates to a drying method for steroidal compound solid materials, which can quickly, efficiently and energy-savingly dry steroidal compound solid materials by means of microwaves. better control. Background technique: [0002] Drying refers to in the chemical industry, often refers to the process of vaporizing the moisture (or solvent) in the material by heat energy, and taking away the generated steam by the inert gas. The drying methods include airflow drying, vacuum drying, freeze drying, and microwave drying. , Infrared drying and high frequency drying methods. Drying is an important part of drug production, and it is a key step to maintain the quality of drugs. If there is no drying step, the stability and accuracy of solid drugs cannot be guaranteed. For solid drying, water (or solvent) diffuses from the interior of the solid to the surface and then vaporizes from the solid surface. The pharmaceutical industry mainly uses vacuum...
