Description
Technical field
The present invention relates to material drying device technical field, more particularly to a kind of vacuum freezing drying device.
Background technology
Vacuum freeze drying is under vacuum conditions, using sublimation principle, the moisture freezed in advance in material directly to be risen
China removes, so that dry materials.At present, in existing vacuum freezing drying device, the heating plate 20 in its vacuum storehouse 10 is led to
Often all it is that heat carrier is done using silicone oil, silicone oil is heated by steam or the grade external heat source of electric heater 30, then uses oil pump
Heat release in heating plate 20 in 40 feeding vacuum storehouses 10, is heated, so circulation, as shown in Figure 1 again behind outflow vacuum storehouse 10.
However, in above-mentioned mode of heating, because silicone oil is in the heating plate in vacuum storehouse, constantly being put along journey from the inlet to the outlet
Heat, temperature is gradually reduced, and forms heating plate leading portion and the back segment temperature difference, and it is uneven that this temperature difference causes dried material to be heated,
Influence freeze-dried material dries uniformity；And, in order to reduce the temperature difference, existing vacuum freezing drying device has to increase oil
The flow of pump, causes oil pump power to increase, and power consumption increases, although the temperature difference has reduced, still there is dried material and is heated
Uneven phenomenon, it is difficult to solve the problems, such as that freeze-dried material is dried inconsistent.
The content of the invention
It is cold that the technical problems to be solved by the invention are to provide a kind of simple structure, the good vacuum of low, effect that consumes energy
Freeze drying device.
To solve the technical scheme that above-mentioned technical problem is used：A kind of vacuum freezing drying device, including vacuum storehouse and
It is connected with vacuum storehouse with the vavuum pump vacuumized to vacuum storehouse, lyophilized heating plate is provided with the vacuum storehouse and is freezed and caught
Hydrophone, refrigeration compressor and expansion valve are externally provided with the vacuum storehouse, the refrigeration compressor, lyophilized heating plate, expansion valve and
Lyophilized water vessel passes sequentially through the connected composition circulation line of pipeline.
Further, between the refrigeration compressor and lyophilized heating plate formed heating agent pipeline, the refrigeration compressor with
Refrigerant pipeline is formed between lyophilized water vessel, also including converging the heat exchange being connected to be exchanged heat with heating agent pipeline, refrigerant pipeline
Device.
Further, vacuum freezing drying device according to claim 1, it is characterised in that：The refrigerant compression
Machine is frequency-changeable compressor.
Beneficial effect：In this vacuum freezing drying device, the lyophilized heating plate in vacuum storehouse constitutes heat pump
Condenser, refrigerant vapour enters heat release in the lyophilized heating plate in vacuum storehouse, because phase transformation is carried out at the same pressure, makes vacuum
Lyophilized temperature of heating plate in storehouse is consistent, and eliminates the temperature difference of lyophilized heating plate upstream and downstream, is heated evenly dried frozen aquatic products, real
Show and dried uniformity；And, condensed refrigerant liquid throttles by expansion valve, and be again introduced into vacuum storehouse lyophilized catches
Hydrophone refrigeration heat absorption, to maintain the low-temperature condition of lyophilized water vessel, lyophilized heater plate and lyophilized water vessel refrigeration are all used
Same set of heat pump, effective reducing energy consumption reduces freeze-drying cost.
Brief description of the drawings
The present invention is described further with reference to the accompanying drawings and examples；
Fig. 1 is the structural representation of vacuum freezing drying device in the prior art；
Fig. 2 is the structural representation of the embodiment of the present invention.
Specific embodiment
Reference picture 2, a kind of vacuum freezing drying device of the invention, including vacuum storehouse 1 and it is connected with to vacuum with vacuum storehouse 1
The vavuum pump 2 that storehouse is vacuumized, lyophilized heating plate 3 and lyophilized water vessel 4 are provided with vacuum storehouse 1, are externally provided with vacuum storehouse 1
Refrigeration compressor 5 and expansion valve 6, refrigeration compressor 5, lyophilized heating plate 3, expansion valve 6 and lyophilized water vessel 4 pass sequentially through pipeline
It is connected and constitutes circulation line.
In the present embodiment, refrigeration compressor 5, lyophilized heating plate 3, expansion valve 6, lyophilized water vessel 4 constitute heat pump refrigerant
Circulation line, the refrigerant vapour of the discharge of refrigeration compressor 5 enters heat release, refrigerant vapour in the lyophilized heating plate 3 in vacuum storehouse
Condensed at lyophilized heating plate 3 and enter reservoir 7 after forming refrigerant liquid, throttled by expansion valve 6, be again introduced into vacuum storehouse
In 1 lyophilized water vessel 4 refrigeration heat absorption, refrigerant liquid gasify at lyophilized water vessel 4 to form refrigerant gas after enter system
Cold compressor 5.Wherein, the lyophilized heating plate 3 in vacuum storehouse 1 constitutes the condenser of heat pump, and refrigerant vapour enters
Heat release in the lyophilized heating plate 3 in vacuum storehouse 1, because phase transformation is carried out at the same pressure, makes the lyophilized heating plate 3 in vacuum storehouse 1
Temperature is consistent, and eliminates the temperature difference of the upstream and downstream of lyophilized heating plate 3, is heated evenly dried frozen aquatic products, realizes and dries uniformity.
And, refrigerant liquid freezes in freeze-dried water vessel 4 and absorbs heat, and refrigeration compressor 5 has drawn heat from lyophilized water vessel 4, no
Need from traditional electric heater or Boiler Steam consumption of calorie, i.e., a refrigeration system need not be additionally set and catch water to lyophilized
Device 4 is freezed, and effectively causes that lyophilized energy consumption cost greatly declines.
Wherein, it is heating agent pipeline, refrigeration compressor 5 and lyophilized water vessel 4 between refrigeration compressor 5 and lyophilized heating plate 3
Between be refrigerant pipeline, present invention additionally comprises the heat exchanger 8 that be connected to be exchanged heat is converged with heating agent pipeline, refrigerant pipeline, make
Before the discharging refrigerant steam of cold compressor 5 enters lyophilized heating plate 3, first pass through heat exchanger 8 and exchanged heat, eliminate the mistake of exhaust
Temperature, it is ensured that temperature stabilization.
Preferably, refrigeration compressor 5 is by variable-frequency motor control, variable-frequency motor is according to lyophilized technique curve to refrigerant compression
Machine 5 is controlled.
Embodiments of the present invention are explained in detail above in conjunction with accompanying drawing, but the invention is not restricted to above-mentioned embodiment party
Formula, in the ken that the technical field those of ordinary skill possesses, can also be before present inventive concept not be departed from
Put that various changes can be made.
