A small multi-function electric heating heat reflux extraction and
concentration unit
This unit is the active ingredient in pharmaceutical extraction and
concentration combined device, the advantage is a concentrated
extract, in the heat extraction process, extraction tank of liquid
through the filter layer to connect into the heater, evaporator,
for circulating concentration, extraction and condensed steam
produced by the second, after special condenser and heat after
condensation condensate to flow back to extract the material deep
tank, so that full access to materials, has played a dynamic role
in solvent extraction and complementary, while reducing the time of
extraction and concentration, significantly increase productivity
and drugs cream rates.
Principle
Low-temperature thermal reflow of Chinese medicine is a combination
of enrichment units return percolation extraction, countercurrent
extraction and heat reflux extraction of concentrated extract four
kinds of principle, the Chinese medicine extraction, concentration,
two processes simultaneously, a complete traditional Chinese
medicine extraction, concentration, new technology, and to improve
the work of extracting the tank temperature was controlled at 50~
70 ℃, the largest Chinese herbal medicine has maintained the loss
of the active ingredients will not be evaporated. The same time,
extraction, concentration produced by distilling the second device
into a hot-cold flow into the return condensate, down to extract
the tank, as a new solvent added to the herbs inside, the new
solvent to pass from the upper and lower layers medicine has played
a role in moving too percolation dissolved medicinal extract the
soluble material to reach the bottom of the tank into the
concentrator to concentrate. Based on years of practice and
research, in a vacuum under the effect of low-temperature heat of
vaporization, the concentration difference the greater the higher
the rate of active ingredient extraction, reflux condenser hot
fluid within about 2.53 hours to extract the flux tank to replace
all the original one, so that extraction tank medicine
organizations and the leaching solution of solute in the solute in
unit time to maintain a relatively high concentration difference.
The device features
1, all closed loop extraction and concentration, can be 0.3-0.5
times more energy-saving.
2, according to different drugs to reduce solvent 0.5-1 times,
while the increase in investment and Charging Capacity 30% - 60%.
Plaster rate was 10%.
3, heat reflux, pressure extraction, low temperature concentration
and shorten production time 1 / 3 or more
4, suitable for water extraction or alcohol extraction, recoverable
ethanol, can be with alcohol precipitation, percolation, warm dip,
cold soak, cold soak and other functions
5, cancel the middle of storage and so on, to save investment by
50%.
6, such as increasing the computer display control, concentration,
temperature can be freely set at 55- 80 ℃.
7, equipment, compact structure, easy operation, covering an area
savings of 50%.
