Description
Technical field
The utility model relates to a kind of drying equipment, particularly relates to a kind of vacuum drying chamber for the preparation of beta carotene.
Background technology
Beta carotene is a kind carrot, have another name called provitamin A, it extensively is present in the animals and plants, wherein the highest with content in carrot, capsicum, the pumpkin etc., color is dark orange to kermesinus, extensively apply to painted, simultaneously because it has the vitamin A function in vivo, so the nutraceutical additive of FAO (Food and Agriculture Organization of the United Nation) and the approval of food additives joint committee of the World Health Organization.In the preparation process of beta carotene, can use usually and carry out vacuum drying in the vacuum dryer.
At present, conventional vacuum dryer mostly has an airtight casing, article to be dried are placed in the casing, and by vavuum pump airtight casing is evacuated, thereby by reducing the boiling point of the pressure reduction water in the casing, make the moisture that is attached on the article to be dried evaporate volatilization at a lower temperature and drying.But there are the following problems for traditional vacuum dryer: 1, owing to the thermal energy conduction non-uniform phenomenon can appear in low density gas under vacuum, thereby it is discontinuous that article temperature to be dried is risen, and the inhomogeneous phenomenon of being heated occurs, and influences drying efficiency.2, in use, the inwall of operating room gathers steam easily and forms water droplet, because the operating room is rectangular structure, its top and bottom is all the plane, and water droplet unavoidably by the top drippage, has reduced dry mass if be dropped in undoubtedly on the material that is dried; Because the bottom, operating room also is the plane, and the water that flows to the bottom from sidewall can't gather, be difficult to get rid of simultaneously, increased the humidity in the operating room, strengthened dry difficulty.
The utility model content
At the deficiencies in the prior art, the purpose of this utility model is for a kind of vacuum drying chamber for the preparation of beta carotene being provided, having solved vacuum dryer of the prior art and had slow, the ineffective problem of rate of drying; Simultaneously, can also solve operating room's water dripping on top problem, improve dry mass, thereby improve the production efficiency of beta carotene.
For achieving the above object, the utility model adopts following technical scheme:
A kind of vacuum drying chamber for the preparation of beta carotene comprises the casing of sealing, is located at sample rest stand and heating component in the dry chamber of box house, and vavuum pump; It is characterized in that: be provided with the bleeding point that is communicated with dry chamber at casing, bleeding point is connected with vavuum pump by exhaust tube, and the position of the connector of close vavuum pump is provided with evacuating valve on exhaust tube; The position that is positioned at the evacuating valve left end at exhaust tube also is provided with normally closed air intake branch; Also be provided with the air inlet that is communicated with dry chamber on casing, air inlet is connected with inert gas storaging device by air inlet pipe; The roof of described dry chamber is the domes that are to upper process.
Realize that the purpose of this utility model can also reach by taking following technical scheme:
Realize that a kind of embodiment of the present utility model is: the end that described air inlet pipe is connected with inert gas storaging device is provided with air intake valve.
Realize that a kind of embodiment of the present utility model is: the diapire of described dry chamber is provided with rhone, is provided with the drainpipe of band valve at the lowest part of this rhone.
Realize that a kind of embodiment of the present utility model is: described bleeding point is located at the bottom of casing, and described air inlet is located at the top of casing.
The beneficial effects of the utility model are:
1, the utility model has increased air inlet pipeline, by feeding inert gas, forms convection current in casing, and the gas that evaporates in the sample is extracted out, has improved drying efficiency and drying effect, thereby improves the production efficiency of beta carotene.
2, the utility model is made as the domes that are to upper process with the roof of dry chamber, simultaneously, diapire at dry chamber is provided with rhone, be provided with the drainpipe of band valve at the lowest part of this rhone, not only can avoid the water droplet at top, operating room to drop on the sample rest stand, can also in time discharge the water liquid that accumulates in the bottom, operating room, improve drying efficiency, improve dries quantity, thereby improved the production efficiency of beta carotene.

The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
Specific embodiment 1:
With reference to Fig. 1, the described a kind of vacuum drying chamber for the preparation of beta carotene of present embodiment comprises the casing 1 of sealing, is located at sample rest stand 2 and heating component (not shown) in the dry chamber 11 of box house, and vavuum pump 3; Be provided with the bleeding point 12 that is communicated with dry chamber at casing 1, bleeding point 12 is connected with vavuum pump 3 by exhaust tube 4, and the position of the connector of close vavuum pump 3 is provided with evacuating valve 5 on exhaust tube 4; The position that is positioned at evacuating valve 5 left ends at exhaust tube 4 also is provided with normally closed air intake branch 6; Also be provided with the air inlet 13 that is communicated with dry chamber 11 on casing 1, air inlet 13 is connected with inert gas storaging device 8 by air inlet pipe 7; The roof of described dry chamber 11 is the domes that are to upper process.
