Together, adverse reaction of tcm accident is reported in media often, and is Chinese medicine the main reason for cause herbal medicine efficacy and quality fluctuation phenomenon
The unstability of extraction process product quality.
Traditional Chinese drug inspissation process is the key link of traditional Chinese medicine quality control, and traditional Chinese drug inspissation is that Chinese medicine extract heats in the external world
Under effect, make the process of its solvent evaporation, obtain the process of high concentration Chinese medical concrete.In the process, the boiling of Chinese medicine extract
Point-saturated vapor pressure can be changed with the raising of Solid content concentration in its solution, and both critical physical parameter is drilled
Change trend then directly affects the regulation of the process control procedure of traditional Chinese drug inspissation.
At present, more fall behind for traditional Chinese drug inspissation process mid-boiling point-research of the saturated vapor pressure in this production process, no
Research and development and the actual requirement of engineering of traditional Chinese drug inspissation production technology can sufficiently be instructed.
Therefore, designing and providing one kind can realize that Chinese medicine extract boiling point-saturated vapor pressure detection device is Chinese medicine life
A production field technical problem urgently to be resolved hurrily.
The content of the invention
The invention aims to overcome deficiency of the prior art, there is provided and a kind of Chinese medicine extract dynamic boiling point-
Saturated vapor pressure analyzer, based on dynamic boiling point-saturated vapor pressure correlation theory, it is possible to achieve under the conditions of various concentrations
Chinese medicine extract is in different boiling saturated vapor pressure detection corresponding with its.
The purpose of the present invention is achieved through the following technical solutions.
A kind of Chinese medicine extract dynamic boiling point-saturated vapor pressure analyzer, including vavuum pump, the vavuum pump pass through pipeline
It is connected respectively with No.1 vacuum buffer tank and No. two vacuum buffer tanks, the No.1 vacuum buffer tank and No. two vacuum buffer tanks
Between be connected by pipeline, No. two vacuum buffer tanks by pipeline be connected with turn drying tower, condenser and heating boil
Rise device.
Vacuum valve is provided with the pipeline that the vavuum pump is connected with No.1 vacuum buffer tank, No. two vacuum buffer tanks.
The No.1 vacuum buffer tank top is connected with No.1 vacuum regulating valve and No.1 pressure gauge, and bottom is connected by pipeline
It is connected to No.1 tapping valve.
No. two vacuum buffer tank top is provided with No. two pressure gauges, and bottom is connected with No. two tapping valves by pipeline.
No. two vacuum pressure regulation are provided with the pipeline connected between the No.1 vacuum buffer tank and No. two vacuum buffer tanks
Valve.
No. three pressure gauges are provided with the pipeline connected between the drying tower and condenser.
The ebuillition of heated device is provided with thermometer.
Compared with prior art, beneficial effect caused by technical scheme is：
(1) present invention in, ebuillition of heated device can load relatively large number of Chinese medicine extract, with static method measure boiling point-
Saturated vapor pressure is compared, and this equipment causes it to sample the overall representative of concentration shortage it is possible to prevente effectively from measurement solution detection limit is very few
Detection error caused by property；
(2) in the present invention, using double vacuum buffer tanks-vacuum dual-stage buffer regulation system, it can effectively realize and set
Standby vacustat, avoid the fluctuation of the vacuum in detection process, it is difficult to the phenomenon effectively adjusted；
(3) in the present invention, by the way of same vavuum pump provides double vacuum buffer tanks vacuum source simultaneously, it is possible to protect
Vacuum in card system will not produce larger fluctuation because of the working characteristics of pump in itself, can also reduce equipment cost, keep away
Exempt from equipment waste.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
To become apparent the purpose of patent of the present invention, feature, below in conjunction with the accompanying drawings to the specific reality of patent of the present invention
The mode of applying is further described.It should be noted that accompanying drawing uses using very simplified form and non-accurately ratio,
Only to purpose that is convenient, lucidly aiding in illustrating patent Example of the present invention.
Chinese medicine extract dynamic boiling point-saturated vapor pressure analyzer of the present invention, it is used as detection Chinese medicine extract boiling point-full
With vapour pressure equipment, based on dynamic boiling point-saturated vapor pressure correlation theory, it is possible to achieve for the Chinese medicine under the conditions of various concentrations
Extract solution is in different boiling saturated vapor pressure detection corresponding with its.
As shown in figure 1, Chinese medicine extract dynamic boiling point-saturated vapor pressure analyzer of the present invention, including it is vavuum pump 1, dry
Dry tower 10, condenser 13 and ebuillition of heated device 14.The vavuum pump 1 passes through pipeline and No.1 vacuum buffer tank 6 and No. two vacuum
