Dual and countercurrent ultrasonic equipment designs are assembled from a certain number of units
.
The pre-infiltration equipment, the main body of the extraction equipment, the discharger, the juicer, and the infusion pipeline are connected
.
In the continuous countercurrent process, the work flow is as follows: the cut net medicinal materials or the roots, stems and leaves of plants are passed through the quantitative feeding mechanism.
Evenly put it into one end of the unit, and then slowly push it to the other end of the unit through the screw blade, and automatically discharge it according to a certain time required by the process, while the solvent is quantitatively controlled by the other end with a flowmeter according to the process requirements.
Make the direction of the root, stem and leaves of the medicinal material or plant completely opposite to the direction of the solvent
.
During operation, under the action of the propeller, the medicinal materials are constantly flipped forward to replace and rub with the solvent, and the interface of diffusion is constantly updated to obtain a concentration difference in the whole extraction process, thereby shortening the extraction time and improving the yield of leaching components
.
Since this unit is a closed operating system, it also facilitates the leaching of volatile organic solvents
.
At the same time, the feeding and slag discharge of the unit are automatically completed, and the upper door cover can be opened during cleaning, which meets the CIP requirements
.
If required in production, the dregs containing very few active ingredients discharged from the latter tank can be put into a juicer or solvent recovery device for cleaning, which not only improves the yield of active ingredients but does not pollute the environment, is clean and hygienic, and meets the requirements of pharmaceutical production.
GMP requirements
.
When the liquid level of the solvent reaches 3/4 of the diameter of the cylinder, open the steam valve to heat the solvent.
When the temperature is heated to the extraction temperature, start feeding into the dual and countercurrent ultrasonic equipment.
3r/min (the speed can be adjusted according to the length of the extraction time)
