Abstract
The invention relates to a shelf device of a vacuum freeze drier. The shelf device of the vacuum freeze drier comprises shelves, a hydraulic column and a drying box. The shelves are arranged from top to bottom at equal intervals and hung inside the drying box. Every two adjacent vertical shelves are connected through hinges located at the two ends of the shelves. The front portion of the bottom-layer shelf is connected with the bottom of the drying box through bolts. A side plate is welded on the periphery of each layer shelf. According to the shelf device of the vacuum freeze drier, product trays are removed, the side plate is welded on the periphery of each layer shelf, the shelves replace the trays, and bulk pharmaceutical chemicals are directly frozen and dried on the shelves. The shelf device of the vacuum freeze drier has the advantages that contact thermal resistance does not exist between the bulk pharmaceutical chemicals and the shelves, so that the freeze-drying process is greatly accelerated, and the bulk pharmaceutical chemicals can be rapidly fed, discharged and cleaned.
Description
Technical field
The present invention relates to a kind of vacuum freeze drier, especially a kind of shelf device for vacuum freeze drier.
Background technology
The vacuum freeze drying of product need to be carried out in certain device, and this device is called vacuum freeze drier, is called for short freeze dryer.Freeze dryer is comprised of drying box, water vessel, refrigeration machine, vavuum pump and valve, electrical control gear etc. by structure.
Freeze dryer is comprised of refrigeration system, vacuum system, control system, hydraulic system, baric systerm, heat-exchange system, steam sterilizing system (containing purging system in place) by system, and the principle of freeze dryer as shown in Figure 1.
Having now for the vacuum freeze drier placement needs the shelf of cryodesiccated goods to have two kinds to place the goods forms:
The first, if the cillin bottle freeze-drying of partly jumping a queue (treating being placed in cillin bottle containing aquatic product of freeze-drying), first the cillin bottle of partly jumping a queue is placed on (Fig. 2) in the pallet that can take out the end, after placing on the shelf by pallet, again the end, taken away, only retain frame, role makes the unlikely lodging of goods bottle on the one hand, make on the other hand with the shelf face, fully to contact at the bottom of the goods bottle, to reduce heat transfer (the passing cold) thermal resistance in freeze-drying process, accelerate freeze-drying process, after freeze-drying finishes, again the end, inserted in frame, to take out goods (connecting pallet).
The second, if bulk drug freeze-drying, directly the water-containing material medicine is placed in full chassis, so-called full chassis is for taking out chassis, as its name suggests, that surrounding frame and chassis form one, the end, can not be taken away, before freeze-drying, first the full chassis that fills good goods is placed on every layer of shelf, to coil from shelf and take off again after freeze-drying, then carry out the packing of freeze-drying medicine.
Full chassis generally can produce following problems in freeze-drying:
Full chassis can produce moderate finite deformation in cold process is conducted heat in freeze-drying, cause bottom surface and shelf loose contact, thereby greatly affect diabatic process, (freeze-drying process) extends freeze-drying time greatly, extend sometimes 1/5～1/3 time of whole freeze-drying, energy consumption increases, and scheduling of production is brought to adverse effect.
The distortion of full chassis generally has following two reasons:
(1) full chassis is generally thin-wall construction (thick 1～1.5mm), and area is large (being generally 300mm * 400mm) again, in use procedure, unavoidably bumps again more yielding.
(2), in freeze-drying process, range of temperature large (generally rising at-40 ℃～-50 ℃+30 ℃～+ 40 ℃ left and right) variations in temperature in a big way easily causes the dish distortion.
But can't solve fully before the problems referred to above, cause freeze-drying time greatly to extend, the freeze-drying decrease in efficiency.
Summary of the invention
The present invention is if for a kind of shelf of vacuum refrigerating drier device, for solving the technical problem of full chassis deformation effect diabatic process, accelerates freeze-drying speed, to adapt to the needs of bulk drug freeze-drying.
For achieving the above object, technical scheme of the present invention is: a kind of shelf of vacuum refrigerating drier device, comprise shelf, hydraulic column, drying box, be characterized in: several shelves interval are from top to bottom equidistantly arranged, and hang in drying box, between upper and lower shelf, by the hinge that is positioned at the shelf two ends, connect, bottom shelf front portion is connected with the drying box bottom by bolt, and every layer of shelf surrounding is welded with side plate one.
The height of shelf surrounding welding side plate is 15mm.
Before freeze-drying, in blowing and freeze-drying process, the equidistant shelf of arranging in interval becomes horizontal.
When cleaning and draining, hydraulic column rises to peak, and shelf turns forward.
The invention has the beneficial effects as follows:
(1) cancel the goods pallet, every layer of shelf surrounding welded to one limit (high about 15mm), shelf has just replaced full chassis, and bulk drug is freeze-drying on the shelf directly, and its advantage is bulk drug goods and the contactless thermal resistance of shelf, thereby has accelerated widely freeze-drying process.
(2) before freeze-drying in blowing and freeze-drying process, whole shelf device is suspension status, and it is horizontal that shelf becomes, so that liquid freeze-dried products is placed consistency of thickness (being generally the 10mm left and right), guarantees that freeze drying rate is consistent.
(3) shelf need compare while cleaning thoroughly, shelf meeting run-off the straight, water in cleaning can rush at front portion from the shelf rear portion, and substantially exclude shelf, after repeatedly cleaning draining several times, can reach the purpose of shelf cleaning and draining, after draining, after hydraulic stem moves down, shelf reverts to again level, can enter next freeze-drying process.
The accompanying drawing explanation
Fig. 1 is the freeze-drying system schematic diagram;
Fig. 2 is the goods dish schematic perspective view that can take out the end;
Fig. 3 is structural representation of the present invention;
Fig. 4 is the structural representation of the present invention while cleaning.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As shown in Figure 3, shelf of vacuum refrigerating drier device of the present invention, comprise shelf 1, hydraulic column 2, drying box 3 etc.
Several shelves 1 are equidistantly arranged at interval from top to bottom, and hang in drying box 2, between upper and lower shelf 1, by the hinge 4 that is positioned at shelf 1 two ends, connect, bottom shelf 1 front portion is connected with drying box 3 bottoms by bolt 5, and every layer of shelf 1 surrounding is welded with side plate one.The height of shelf 1 surrounding welding side plate is 15mm.
Before freeze-drying in blowing and freeze-drying process, whole shelf device is suspension status, it is horizontal that shelf becomes, so that liquid freeze-dried products is placed consistency of thickness (being generally the 10mm left and right), guarantee that freeze drying rate is consistent, after the bulk drug freeze-drying finishes, after with vacuum cups, dry raw material medicinal powder being siphoned away, shelf 1 need compare thoroughly and clean, and substantially excludes rinse water (remaining a small amount of water can be taken away with water ring pump or vavuum pump), in order to comparatively fast enter next freeze-drying process.
When cleaning also draining, shelf 1 can be tilted (Fig. 4), and tilting procedure is as follows:
Hydraulic column 2 on shelf device rises to peak, because the anterior orlop plate A of shelf 1 place (left and right 2 points) are be connected with drying box 3 bottoms by bolt 5 (rear portion are not connected), shelf 1 meeting run-off the straight, water in cleaning can rush at front portion from shelf 1 rear portion, and substantially exclude shelf 1, after repeatedly cleaning draining several times, reached the purpose of shelf 1 cleaning and draining, after draining, the hydraulic stem of hydraulic column 2 suitably moves down, shelf 1 reverts to again level, can enter next freeze-drying process.
This device, at present by domestic, external peculiar, has reached above-mentioned gratifying effect.
