Traditional Herb Extraction Equipment Operated Low Temperature 60 -
80°C
Description:
1.Low temperature densely: The main solvent is water and ethanol in
the Chinese extracted, if adopt the low extracting and low
concentrating, the water extracting is control in 50℃-90℃, ethanol
extracting is control in 40℃-80℃. Because of the low extracting, it
can avoid the Chinese medicinal materials active ingredient,
especially the organisms activated not easy to destroy, at the same
time it can avoid producing the inefficacy ingredients in the high
temperature, such as dextrin, colloid, tannin etc, improve the
products quality, convenient for isolation and purification.
2.High drawing rate: Because of the extracting pot at the condition
of the vacuum pressure and low temperature, it can enable the
Chinese medicinal materials cell to expedite expand, cell membrane
broken at once, at cell inside, it stripping the active ingredient.
And the continuously supplement of the reflus-norma new solvent,
which it enable the solvent played at the medicinal materials
surface and penetrate into the medicinal materials interior,
improve the medicinal attrition elution-force and the solubility,
the medicinal material and the solvent keep higher gradient of
concentration and extend ability, having accelerated the dissolving
out of solvent of active principle of the medicinal materials
,improve the extracting rate and the harvested ointment rate of the
Chinese medicinal material.
3.Save the solvent: Only need to join 8 times of solvents of crude
drugs quantity once, utilize new solvent conduct of hot backset
current to hot backset current to supplement, which the backset
total is equal to the old extracting need 2-3 times join solvent
total, it save the solvent 50%-60%, also it can increased the
collecting volume of medicinal materials.
4.Save steam, the unit in closed and low temperature operation, all
maintained liquid temperature in the tank keep in 50-90℃, heated
steam pressure in atmospheric conditions, can significant reduction
of the steam power consumption.
5.Design innovation: Through the vacuum of the vacuum converter and
the height difference of the vacuum height suction of the key
design, it shorten the extracting and contracting time, improve the
medicinal harvested ointment rate and some active ingredient
keeping rate.
Applications:
Traditional Chinese medicine hot backset current low temperature
draw low temperature concentrate unit comprehensive backset
current, ooze and filter drawing, adverse current and hot backset
current extraction and concentrate four kinds of principles.
abstraction, concentrate two processes go on at the same time, one
finish traditional medicine draw, concentrate the new craft of
traditional Chinese medicine, take to change the draw pot keep high
temperature with atmosphere fry the craft of boiling, utilize
vacuum to shoulder proceed low temperature draw and low temperature
concentrate, make working temperature to draw pot control in
60-80°C, concentrate temperature control in 50-70°C, guarantee
crude drugs effective composition the distillation loss. Meanwhile
draw and concentrate produced two steam enter backset current
condenser become hot condensation liquid, falling back to and
drawing it the pots, add to the crude drugs as the new solvent, the
new solvent is passed the crude drugs layer from top to bottom,
having played a oozing and filtering dynamically role, the soluble
material which dissolves the crude drugs reaches the draw pot
bottom, enter the concentrating device to concentrate again.
According to practical experience and study for many years, hot
condensation liquid of backset current invite within 2.5-3 hours
drawing former solvent of pot all change once, can keep a higher
density to the draw pot crude drugs in unit time.
