Material information controls turning off or on for electromagnetic air releasing valve 19, and when electromagnetic air releasing valve 19 is opened, the vacuum in vacuum line is fast
Prompt drop is low, and the vacuum in material container 7 is destroyed, and foam is ruptured rapidly.
The material container 7 is made up of bottle for material 20 and bottle cap 21, the two hermetic seal connection, the vacuum exhaust pipe 6, thing
Material temperature sensor 8 is connected with the hermetic seal of bottle cap 21.
Referring to application method and operation principle of Fig. 1 and Fig. 2 descriptions according to the present invention.
Chinese medicine extract concentrate drying is to dry extract：By material (Chinese medicine extract, glue class, honey or single pan-fried precious Chinese medicine
Medicine materical crude slice extract solution etc.) material container 7 is put into, bottle for material 20 and bottle cap 21 are sealed to ensure the vacuum in container, by material
Temperature sensor 8 and the access bottle cap 21 of vacuum exhaust pipe 6, the wherein detecting head of temperature of charge sensor 8 will be placed in the middle of material,
Vacuum exhaust pipe 6 will be placed in more than material liquid surface.Vacuum condenser 3 is started by controller 4 and extracts vacuum, when material container 7
Interior vacuum reaches after setting value (such as -0.08Mpa) that controller 4 restarts micro-wave oven 2, and temperature of charge is begun to ramp up, thing
Expect temperature sensor 8 by the temperature of charge data transfer measured to controller 4, when temperature of charge reaches setting numerical value, control
Device 4 makes temperature of charge constant in setting value by closing, unlatching micro-wave oven 2 or the power output by adjusting micro-wave oven 2.
A large amount of foams can be produced when material is concentrated to a certain degree, cause liquid level to raise rapidly, material will be inhaled into vacuum and take out
Tracheae 6 is simultaneously overflowed, and now material liquid surface is contacted with material inductor 14, and when material inductor 14 detects foam, information is passed
Controller 4 is delivered to, controller 4 is by adjusting the vacuum in the electromagnetic air releasing valve 19 on vacuum condenser 3, destruction material container 7
Degree, makes foam rupture rapidly, and liquid level declines, and vacuum is raised again in material container 7, and material seethes with excitement again, liquid level rise with
Material inductor 14 is contacted, and controller 4 is again started up electromagnetic air releasing valve 19, after being repeated several times, and material remains relatively low liquid level
The boiling of height, so as to avoid loss of material.
Vacuum exhaust pipe 6 is stored in liquid-collecting bottle 17 after the condensed pipe 18 of the steam of extraction is cooled down, as concentration is continuous
Carry out, the vapor (steam) temperature in vacuum exhaust pipe 6 is also constantly changing and existed to the degree of concentrate drying certain related
Property.Accompanying drawing 2 is vapor (steam) temperature-concentrate drying state change curve for Chinese medicine extract, and wherein relative density is actual measurement number
According to 30 times of amplification, from figure 2 it can be seen that in the Chinese medicine extract concentrate drying stage, vapor (steam) temperature by the rising stage, stationary phase,
Decline phase three phases are constituted, and each temperature spot corresponds to different relative densities, sentenced by presetting vapor (steam) temperature
The degree of disconnected material concentrate drying, when vapor (steam) temperature is T1, the relative density of concentrate is 1.1-1.2；When vapor (steam) temperature is
During T2, the relative density of concentrate is 1.2-1.3；When vapor (steam) temperature is T3, the relative density of concentrate is 1.3-1.4；When
When vapor (steam) temperature is T4, material turns into dry extract, so as to accurately judge material concentrate drying by on-line checking vapor (steam) temperature
Degree.
As concentration is constantly carried out, the weight of material is also constantly mitigating, set by the weight in advance to material,
The degree of concentrate drying can be accurately judged by on-line checking weight of material.
Vapor (steam) temperature detect and weight of material detection both can individually carry out, can also the two be combined, can realize and sentence
The purpose of disconnected concentrate drying terminal, when the two is combined, can exclude more interference, the result of detection is more accurate.
Involved various components in the present embodiment, such as micro-wave oven, vacuum condenser, controller, temperature sensor,
Electronic scale, electric up-down plate, electromagnetic shielding plate, material inductor, electromagnetic air releasing valve etc. are well known to the skilled person
Prior art, those skilled in the art can be commercially available by various commercial sources, can also be according to institute in the present embodiment
The product function designed, designed of description.
