Description
Technical field
The utility model belongs to bio-pharmaceuticals chemical technology field, and in particular to a kind of detection vacuum freeze drier in real time
The device of sample drying degree.
Background technology
Vacuum freeze drier is suitable for high-grade bulk pharmaceutical chemicals, the prepared slices of Chinese crude drugs, biology, wild vegetable, dehydrated vegetables, food,
The drying of the materials such as fruit, chemical industry, pharmaceutical intermediate.Traditional bell-jar vacuum freeze drier is because of simple in structure, cost
It is cheap, using than wide.Freeze-drying situation cannot be accurately grasped during sample is lyophilized, when being generally used extension freeze-drying
Between method, do so some faces and waste time, on the other hand waste the resources such as electricity.
Utility model content
The purpose of this utility model is to provide a kind of device of real-time detection vacuum freeze drier sample drying degree, solution
Vacuum freeze drier existing in the prior art of having determined cannot monitor the problem of sample freeze-drying situation in time.
The utility model is the technical scheme adopted is that a kind of real-time detection vacuum freeze drier sample drying degree
Device, including host are provided with hothouse on host, electronic scale dress are provided at hothouse and the cold-trap contact position on host
It sets.
The utility model is also characterized by
Operable touch screen is additionally provided on host, operable touch screen is connect with power switch and electronic scale device.
It is additionally provided with vacuum pump connector on host, vacuum pump is installed at vacuum pump connector.
Vacuum pump connector is located at hothouse and the positions host 10~20cm of contact surface.
Hothouse is internally provided with specimen holder.
The utility model has the beneficial effects that the device of vacuum freeze drier sample drying degree is detected in real time, dry
It is provided with electronic scale device at dry room and the cold-trap contact position on host, sample can be detected in real time using the function of this device
In addition the mass change of freeze-drying sample.
Description of the drawings
Fig. 1 is the structural schematic diagram for the device that the utility model detects vacuum freeze drier sample drying degree in real time;
Fig. 2 is the device use touch in the process that the utility model detects vacuum freeze drier sample drying degree in real time
Screen curve figure.
In figure, 1. hosts, 2. specimen holders, 3. hothouses, 4. operable touch screens, 5. power switches, 6. cold-traps, 7. electronics
Scale device, 8. charge valves, 9. vacuum pump connectors, 10. vacuum pumps.
Specific implementation mode
The utility model is described in detail with reference to the accompanying drawings and detailed description.
The utility model it is a kind of it is real-time detection vacuum freeze drier sample drying degree device, structure as shown in Figure 1,
Including host 1, it is provided with hothouse 3 on host 1, electronic scale is provided at hothouse 3 and 6 contact position of cold-trap on host 1
Device 7 is additionally provided with operable touch screen 4 on host 1, and operable touch screen 4 is connect with power switch 5 and electronic scale device 7,
It is additionally provided with vacuum pump connector 9 on host 1, vacuum pump 10 is installed at vacuum pump connector 9, vacuum pump connector 9 is located at
At hothouse 3 and 1 positions 10~20cm of contact surface of host.
Hothouse 3 is internally provided with specimen holder 2.
A kind of device of real-time detection vacuum freeze drier sample drying degree of the utility model, operation principle are as follows:
When needing drying sample, refrigeration machine starts running, and condenser temperature continuously decreases.To make cold-trap that there is fully absorption water
The ability of part, pre-coo time should be no less than 30 minutes.After precooling, waited for what is frozen in ultra low temperature freezer or liquid nitrogen in advance
Dry goods are placed in the specimen holder 2 of hothouse 3, lucite cylinder on cover, are closed charge valve 8, are shown sample quality at this time, so
After open vacuum pump, vacuum pump is started to work, and " vacuum degree " display declines until 20Pa is hereinafter, freeze-drying process starts,
Select required curve type (sample temperature, sample quality, cold-trap, vacuum degree), selected curve can be real on operable touch screen 4
When be shown in touch screen corresponding position, when " sample quality " curve when not changing for 1 to 2 hour, it is dry to illustrate that sample is completed
It is dry.At this point, slowly opening " charge valve " first, vacuum pump is simultaneously closed off, air is made to slowly enter cold-trap, then power-off lifts and has
Machine cloche, article is taken out, and is preserved, and freezing dry process terminates.
Remarks:In the present invention, the sample quality dried must not exceed the specified biggest quality of freeze drier
Range, other points for attention are identical as normal freeze-drying machine.
As shown in Fig. 2, operable touch screen 4 now has three sample temperature, condenser temperature and vacuum degree parameter songs
Increase a sample quality curve on the basis of line.
