Problems solved by technology
Among them, the tiltable reaction pot is generally used for the final concentration and collection of ointment. This kind of pot has a high evaporation temperature, a long time for the material to be heated, and heat-sensitive components are easy to coke. Hygiene
The vacuum concentration reaction pot cannot accurately control various process parameters in the concentration process, and the concentration effect is poor
Due to the high evaporation temperature of thin-film concentration evaporation equipment, and the evaporation temperature and feed volume cannot be automatically controlled, coking often occurs
Double-effect and triple-effect external circulation concentration and evaporation equipment are commonly used at present. They have the advantages of fast evaporation speed and high density extract, but the density of each effect cannot be automatically detected, and manual operation is required for feeding and discharging materials, without temperature and pressure. And the vacuum automatic control system, the vacuum and condensation system consumes a lot of energy, and the equipment is inconvenient to clean

Embodiment Construction
[0015] As shown in Fig. 1 and Fig. 2, at first the evaporator 9 and the heating tank 14 are selected, and the upper and lower ends of the heating tank 14 are connected with the evaporating tank 9 to form a circulation loop. The upper connecting pipe 15 is tangent to the evaporation tank as shown in Figure 3, and the inner diameter of the upper connecting pipe 15 must be smaller than the inner diameter of the upper cavity 36 of the heating tank 14; The infusion pipeline 34 connecting the liquid supply tank 1 and the evaporating tank 9 enters the tank body from a position higher than the upper connecting pipe 15 at the upper part of the evaporating tank and extends to the lower part of the tank body. A concentrate pump 26 is connected to the connecting pipeline between the evaporation tank 9 and the heating tank 14 through a valve and a hose. The steam distributor is connected to the heating tank 14 through a pipe 35 . The gas-liquid separator 16 is connected by a pipeline at t...

A process for the vacuum concentrating of the liquid Chinese medicine features that said liquid Chinese medicine is concentrated by heating with steam and evaporating in a circulation loop in vacuum state and consisting of evaporating tank and heating tank. Its system is composed of heating tank, evaporating tank, connecting pipelines, condenser, vacuumizing unit, liquid supplying tank, liquid conveying pipe, and control unit.
Description
technical field [0001] The invention relates to a process for concentrating traditional Chinese medicinal liquid in a vacuum state and vacuum concentrating equipment used in the process. Background technique [0002] The equipment used in the existing traditional Chinese medicine liquid concentration method mainly includes tiltable reaction pot, vacuum concentration reaction pot, thin film concentration and evaporation equipment, double-effect and triple-effect external circulation concentration and evaporation equipment, etc. Among them, the tiltable reaction pot is generally used for the final concentration and collection of ointment. This kind of pot has a high evaporation temperature, a long time for the material to be heated, and heat-sensitive components are easy to coke. hygiene. The vacuum concentration reaction pot cannot accurately control various process parameters in the concentration process, and the concentration effect is poor. Due to the high evaporation te...
