In the production of proprietary Chinese medicines, the extraction process is the main process. From conventional single-stage reflux leaching extraction to hot reflux extraction concentration extraction, from dynamic extraction to continuous reverse leaching extraction, from enhanced leaching such as ultrasonics, electromagnetic strengthening, etc. to supercritical fluid extraction, leaching process equipment has been completed A leap forward, but what can really be developed is the equipment that this many-time leap involves.

In the case of supercritical fluid extraction equipment, its research and development is based on a process research institute. For a new drug extraction, first of all, it must study its extraction critical temperature, critical pressure and other process parameters in order to convert from the “small test”. For normal production, this shows the process of promoting equipment by the process.

However, the extraction of supercritical fluids also has certain limitations. Its extraction range is limited. This is due to the fact that the supercritical extraction is based on the separation factors in the extraction process that the natural substances contain various components in the critical fluid with different solubilities. There is also the potential for the development of extraction equipment, and of course, other process equipment for proprietary Chinese medicines.

Chinese medicine equipment manufacturing companies also need to learn and introduce new technologies, and they must make progress in equipment with high production efficiency, high degree of automation, good reliability, flexibility, and high technological content to create new types of machinery and equipment and gradually move toward modernization.

The GMP verification of Chinese proprietary Chinese medicines has just started and it is urgently needed to produce scaled-production Chinese patent medicine equipment. Therefore, the equipment in this field has more extensive research and development value. With the continuous development and progress of science and technology, the future microelectronics, computers, industrial robots, image sensing technology and new materials will be more and more widely used in drug machines.
