technical field

The utility model relates to the technical field of processing medicinal excipients, in particular to an anti-scald thermal insulation vacuum drying oven for the processing of medicinal excipients.

Background technique

Pharmaceutical excipients refer to the excipients and additives used in the production of drugs and the formulation of prescriptions. They are substances other than active ingredients that have been reasonably evaluated in terms of safety and are included in pharmaceutical preparations. In addition to excipient, acting as a carrier and improving stability, it also has important functions such as solubilization, solubilization, slow and controlled release, etc. It is an important ingredient that may affect the quality, safety and effectiveness of drugs. During the processing of pharmaceutical excipients It needs to be dried in the process of drying. At present, the commonly used drying equipment is a vacuum drying oven, which is easy to control, and the medicinal excipients are not easily contaminated during the drying process.
