Plant extraction process
1. Select plants/medicinal materials. It is nothing more than ancient prescriptions, proven prescriptions, and folk medicinal herbs. At present, common and uncommon medicinal materials have been studied. Most of the time, the amount of medicinal materials has been increased to extract low-isolated components, or medicinal plants have not been studied from Miao medicine, Tibetan medicine, Mongolian medicine, Africa, Latin America and other places.
2. Extract. Solvent petroleum ether, n-hexane, cyclohexane, benzene, chloroform, ethyl acetate, n-butanol, acetone, ethanol, methanol, water (small polarity → large polarity). Daily decoction of medicines is effective, use water and ethanol and other solvents with high polarity. Artemisinin and other boiling methods are not effective, use petroleum ether and other solvents with low polarity. The common medicinal materials, water/alcohol/ether, are presented again, and more compounds can be separated and identified.
3. Separation. This is the most important task. There are dozens of compounds in the solution extracted in the second step. Generally, column chromatography is used, which is what we often call column flushing. The workload is large, boring, and low-tech. A master's degree may do this every day for 2 years of experimentation. As shown in the figure below, the column for separating compounds is as large as 2 meters high and as small as 10 cm. Change the solvent conditions of the mobile phase, change the material of the column, and repeatedly wash the column under different conditions and separation principles to separate the monomer compound.

Dryer installation and commissioning and precautions
Dryer installation and commissioning and precautions:
When the dryer is transported by the manufacturer to your factory, you must first perform a routine inspection of the dryer to check whether it is the machine you purchased and whether it is damaged or unusable during the delivery process. Photographs should be taken immediately and with the manufacturer.
Before the dryer, you should determine the installation position of the dryer. The installation location of the dryer should consider the location of the transportation channel, raw material turnover, water intake, steam inlet and sewer pipe. Here, the Xingxing washing equipment reminds you that the dryer should be installed. Together with equipment such as dehydrators and dryers, the distance between these devices is reduced to prevent subsequent troubles due to improper selection of locations.
The dryer belongs to one of the larger and heavier laundry equipment, so the machine should be installed on a solid foundation and kept horizontal to prevent the equipment from working due to the location of the site and the uneven installation site. Large vibrations occur, which affects the washing efficiency and the life of the dryer.
Refer to the dryer instruction manual, find the electrical control cabinet door of the industrial washing machine according to the relevant content in the manual, and connect the 380V three-phase power supply line and the neutral line according to the binding post (the need to remind here is: the electricity consumption of the dryer) Must be 380V, no access to low voltage or high voltage)
Referring dryer body corresponding access label instructions inlet conduit and steam pipes, such as steam does not have the condition, the steam inlet may be blocked. If steam heating is used, install pressure indicating devices and safety devices at the obvious location of the steam main pipe outside the machine.
