Thermal reflux distillation concentrator
 
Equipment features:

1. The rate for plaster collection is 10-15% higher than that of the multi-function tank, and the effective elements in the plaster is one time higher than the normal one. Because the hot 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 during the extraction, so the solute in the drug material and the solute in the solvent keep in high-gradient. If the solute in the drug material can be separated out with high speed until it separates out completely, then the extraction extent of the effective content is high. Because the evaporation is finished inside the seal device with little loss and high transformation rate, so the rate for cream collection is high and the effective element inside the drug cream is high.

2,For the factors of high speed of separation out of solute, short time of extraction and the evaporation is synchronized with extraction, the time from changing the drug material into the concentrated drug cream is only seven to eight hours, which has the advantage of high facility availability,

3,The equipment has the advantage of simple and small floor space and high equipment availability, so the cost is lower.

4,The extraction just needs to add the solvent one time, 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 in extraction of organic solvent and purification of effective content in the China traditional medicine.

5,For the evaporated secondary steam serves as the heat source of extraction, the extraction liquid pumped to the evaporator is at the same temperature level with that of the evaporator, which can save the steam for more than 50% and feature easy operation and reduces the operator.
 
Function:

The device serves for vegetable and herbal medicine, china traditional drug, animal, food additional extraction with water, ethanol, methanol and acetone, which also can be used to recycle and concentrate the organic solvent.
