Problems solved by technology
[0002] At present, there are many problems in the wiped film molecular still. During the distillation, the time required for distillation cannot be controlled, and the temperature can only be adjusted by controlling the heating tube. This often fails to achieve the best effect of liquid medicine distillation. After the distillation is completed, there will often be liquid medicine remaining on the condenser tube, so it is often necessary to wait for the liquid medicine to drip automatically or use an external force to make the liquid medicine drip from the condenser tube. When cleaning the inside of the distiller, it is often necessary to disassemble the distiller Clean the inside, such multiple disassembly will cause gaps in the distiller, and the best vacuum state cannot be achieved, which will affect the distillation effect

The invention discloses a pharmaceutical wiped film type molecular distiller, which comprises a casing, wherein a vacuum machine is fixedly arranged on the top wall of the casing, an annular pipe is fixedly arranged on the top wall of the casing, a medicine inlet pipe is slidably connected in the annular pipe, a lifting device is arranged in the annular pipe, a cavity is arranged in the casing, and a liquid scraping device, a wiped film device, a rotating device, a telescopic device and a scrubbing brush device are arranged in the cavity. According to the invention, the position of a spray head is controlled through a rack and a gear, the heating time of liquid medicine on the side wall of the cavity can be controlled, the influence on liquid medicine distillation due to too long or too short heating time is avoided, the liquid medicine can be scraped into a liquid film state by controlling the film scraping brush through the motor and the connecting rod, the efficiency during liquid medicine distillation is improved, residual liquid medicine is scraped off through the scrubbing brush, liquid medicine waste caused by the fact that the liquid medicine is left on the connecting rod is avoided, and the recovery rate of the liquid medicine is effectively improved.
