Equipment feature
1.The rate for cream collection is 10～15% higher than that of the multiple function tank, and the effective content inside the cream is one time higher than the normal one. Because the heat solvent is added into the drug surface continuously and then they pass the drug layer from up to down with high speed to solve the solute in the drug material during the extraction, so the solute inthe drug material and the solute in the solvent keep high grads. If the solute in the drug material can separate out with high speed until it separates out, then the extraction extent of the effective content is high. Because the concentration is finished inside the seal device with little loss and high transformation rate, so the rate
for cream collection is high and the effective content inside the drug cream is high. .
2.For the factors of high speed of separation out of solute、short time of extraction synchronous operation of concentration and extraction, the time from changing the drug material into the concentrated drug cream is only seven to eight hours, which
highlights high equipment utility. .
3.The equipment is simple and has little use area and features high equipment utility, which highlights economic investment.
4.The extraction just needs one time of use of solvent, which is used cyclically in a set of seal equipment. The solvent in the
drug residue can be reclaimed basically, which makes the solvent quantity is 30% less than that of the multiple function extraction tank and the solvent consumption is 50~70% less than that of the multiple function extraction tank. The above advantages make it available the extraction of organic solvent and purification of effective content in the China traditional drug. .
5.Fot the concentrated secondary vapor serving as heat source, the extraction liquid into the concentrator is at the same
temperature level with that of the concentrator, which can save the vapor for more than 50% and feature easy operation and
reduces the operator.
Operation principle
Put the drug material into the extraction tank and insert the solvent such as water、ethanol、carbinol and acet, etc (in accordance with
the technology requirement) whose capacity is five to ten times the drug material. The tee in the extraction tank and the vapor valve of clip
sleeve open to heat the extraction liquid until boil that will last for about twenty to thirty minutes. And then, the extraction & filter pipe sorbs
one third extraction liquid into the concentrator. And the tee in the extraction tank and the vapor valve of clip sleeve are closed and the
heater valve is opened to concentrate the material liquid. The second vapor produced during concentration can enter the extraction tank
through the upward pipe at the evaporator to serve as the heat source for extraction to maintain the boil inside the tank. .
The second vapor continues rising to change into the condensation liquid by the condensor and falls back inside the extraction tank
to serve as new solvent to be added at the drug surface. The new solvent arrives down at the bottom of the extraction tank throughout the
drug material layer. The dissoluble effective content at the drug material is resolved into the solvent inside the extraction tank. The
extraction liquid enters the concentrator by the extraction & filter pipe and the second vapor produced for concentration arrives the
extraction tank to serve as heat source and new solvent. The extraction of new solvent with large circumfluence can make the density
of the drug material and solvent at high grads. The solvent in the drug material separates out at high speed until a complete separation
(i.e. the extraction liquid is colorless.) . Then, the extraction liquid stops entrance of the concentrator. The concentrated second vapor
enters the cooler to continue concentration until the drug cream with required proportion(1.2~1.34) is available. The colorless liquid
inside the extraction tank can be stored at the storage tank for reuse. The drug residue is drained out of the residue outlet. In the case
of extraction with organic solvent, it is necessary to add proper water and open the tee and the clip sleeve vapor valve. After reclamation
of solvent, the residue is drained.
