Outer circulating concentration equipment is a satisfactory device for manufacturing herbal liquid extract. Its characteristics are as follows: high efficiency, fast evaporation, good defoaming effect, easy to operate, small in size, low maintenance and easy to clean. The ratio of the heating area and condensation area is reasonable, contributing to a good solvent recovery effect. Distilled water recovered can be reused, so the equipment is energy saving. Control the degree of vacuum (-0.08Mpa), cooling water temperature (25-38℃), flow rate and liquid level for continuous concentration. Conduct automatic control over vacuum, pressure, temperature, liquid level, ratio of herbs and liquid, alcohol recovery concentration and cleaning through the console. When installing the equipment, ensure the steam inlet valve is fitted with a safety valve and pressure gauge to prevent overpressure operation. At -0.08Mpa, the boiling point of water is 60 ℃, so ensure the steam pressure<0.1Mpa.） Structural characteristics are as follows: 1、Outer circulating concentration pot: consists of the heating chamber, evaporation chamber, condenser and cooling water tank. Its features are as follows: 1) Fast evaporation and good defoaming effect. 2) Easy to operate, small in size, low maintenance and easy to clean. 3) Can produce extract with a large proportion of 1.4. There are two steam jackets in the evaporation chamber, so air and heat can be provided through the upper or lower jacket according to the liquid level, which can prevent pasting the pot. 4) Can produce extract with different proportions through the outer circulating heater and evaporation pot. 5) Prevent blocking tubes. The design is reasonable and efficient, so it takes a short time from preheating, heating to filming. 6) Low temperature won’t destroy heat-sensitive materials in herbs. 7) The recovered solvent can be reused, so as to reduce production costs. 2 、Single-efficiency outer circulating evaporator 1 ) Fast evaporation and good defoaming effect. 2 ) Easy to operate, small in size, low maintenance and easy to clean. 3 ) Can produce extract with a small proportion of 1.3 or less. 4 ) Prevent blocking tubes. The design is reasonable and efficient, so it takes a short time from preheating, heating to filming. 5 ) Low temperature won’t destroy heat-sensitive materials in herbs. 6 ) The recovered solvent can be reused, so as to reduce production costs. 3、 Single and double-efficiency concentration pot 1 ) It’s energy saving and multi-functional. It can be used for single-efficiency or combined concentration to produce extract with different proportions, and can also be adjusted for double-efficiency concentration according to production needs. 2 ) Fast evaporation and good defoaming effect. 3 ) Easy to operate, small in size, low maintenance and easy to clean. 4 ) Can produce extract with a large proportion of 1.4. There are two steam jackets in the evaporation chamber, so air and heat can be provided through the upper or lower jacket according to the liquid level, which can prevent pasting the pot. 5 ) Can produce extract with different proportions through the outer circulating heater and evaporation pot. 6 ) Prevent blocking tubes. The design is reasonable and efficient, so it takes a short time from preheating, heating to filming. 7 ) Low temperature won’t destroy heat-sensitive materials in herbs. 8) The recovered solvent can be reused to reduce production costs. |
