High vacuum heat pump double effect concentrator

The high vacuum heat pump double effect concentrator has changed the traditional condensation mode of concentration With the improved double effect technology of heat pump, the vacuum degree is higher, the stability is better, and the energy-saving effect is remarkable It is especially suitable for the concentration process with high saponin content, high sugar content and strong heat sensitivity The main features of the unit are as follows: (1) high vacuum: spray mass transfer condenser, no need for cooling tower, less water consumption and less power consumption, 1.5kW less than -0.085MPa, vacuum degree above The technology has been invented by the state (2) defoaming Technology: Chinese herbal medicines commonly contain high sugar content and high saponins When they are concentrated, they are prone to foam They often appear boiling and running away, which increases operation difficulty and reduces production efficiency The high vacuum heat pump double effect concentrator adopts spray technology, and successfully solves the problem of defoaming in concentration (3) antiscaling Technology: the forced external circulation three pass design is adopted, which greatly increases the flow rate of the liquid medicine in the column, reaching more than 2m / s The steam jet pump is adopted to make the temperature of the heating mixed steam not more than 90 ℃, which greatly prolongs the strong washing cycle, and the scale is very thin and easy to clean (4) energy saving: spray condensing condenser and forced circulation pump, saving electricity and saving solar term For example, for a 2000L high vacuum heat pump double effect concentrator, the total power consumption of the condensing system is 9.1kw, and only 0.37t steam is needed to evaporate 1t water (5) automatic control technology: automatic control of liquid level, steam pressure, liquid inlet temperature and defoaming, which greatly reduces the labor intensity of operators while reducing material running.
