Abstract
The utility model relates to a novel bottom-drawing type freeze-drying pallet frame. The frame is provided with a middle clapboard which divides the middle part of an outer frame into a plurality of cells; and medicine bottles to be frozen out are arranged inside the cells. A laboratory or big production adopting the frame can reduce freeze-drying time, increase freeze-drying efficiency and save energy source.
Description
Technical field
The present invention relates to a kind of freeze drying and take out the framework of end formula freeze-drying pallet.
Background technology
During the medicine freeze drying, the effect of taking out end formula freeze-drying pallet and framework thereof is exactly the splendid attire medicine bottle and it is sent into freeze dryer.The end formula freeze-drying pallet of taking out commonly used both at home and abroad at present comprises a pallet and a framework, pallet is similar to drawer, be a hollow, no end face, and lack the cuboid metal structure of a side, other three sides are a little more than the bottleneck of splendid attire medicine bottle, and the size of pallet is often determined according to the situation of freeze dryer; Framework is the cuboid metal structure of a hollow, no bottom surface, no end face, and length is slightly less than pallet, can put pallet into just, earlier medicine is piled up in pallet during use, packages framework then from top to bottom.
In the freezing dry process of medicine, the heat of each medicine bottle is different, the medicine bottle of center, because surrounded by synthermal medicine bottle on every side, heat mainly passes toward goods by the bottom surface.But the medicine bottle near framework except being subjected to the heat transmission of bottom surface, also is subjected to the heat transmission of framework easily.Therefore near the medicine bottle of framework than the central part medicine bottle receive heat many, rate of drying is very fast relatively.Need extend during the medicine freeze drying time of a lyophilization, otherwise the medicine in the medicine bottle of center does not freeze just to enter redrying fully, part, goods bottom can take place dissolve, cause product rejection.So in order to reduce the fraction defective of product, guarantee uniform in quality, just necessary proper extension sublimation drying, but also wasted the more energy simultaneously, improved cost.
Summary of the invention
The invention provides a kind of general frame of establishing separation.This framework is made up of the dividing plate of centre and outside framework all around.Outside framework is with general freeze-drying tray frame unanimity, the cuboid metal structure, and hollow, no bottom surface and end face, length is slightly less than pallet, just in time can put pallet into; Central dividing plate is connected and fixed by welding and outside framework wall, being divided into some unit in the middle of the outside framework, medicine bottle is arranged in the cell, the height of central dividing plate, thickness and length are identical with outside framework, distance between dividing plate and outside framework wall and the dividing plate is 16.00～30.00mm (deciding the bottom surface diameter of an about medicine bottle on medicine bottle bottom surface commonly used diameter).Outside framework and middle dividing plate adopt freeze-drying pallet identical materials usually, generally adopt stainless steel.
The setting of this dividing plate can improve the heat transmission of medicine bottle.Whole framework is not because character own can discharge latent heat in precooling process, and temperature can be a little less than medicine bottle; Can be in a lyophilization and redrying process median septum owing to heat is not taken away in the distillation and the evaporation of moisture yet, temperature can be a little more than medicine bottle, and heat transmission all can take place in outside framework, dividing plate and close medicine.In the whole process, the temperature of dividing plate and outside framework is identical, and is basic identical with the situation that the heat of adjacent medicine bottle generation is transmitted, and the situation that the heat that each locational medicine bottle is subjected to transmits is also basic identical, and product is heated evenly.

The specific embodiment
The framework of taking out end formula freeze-drying pallet of the present invention, as shown in Figure 1, 2, form by outside framework 1 and central dividing plate 2, distance between dividing plate 2 and outside framework 1 and the dividing plate 2 is that 16.00～30.00mm (decides on medicine bottle bottom surface commonly used diameter, the bottom surface diameter of an about medicine bottle), dividing plate 2 is fixing by welding with outside framework 1 wall.Outside framework 1 and dividing plate 2 all adopt stainless steel to make.
The medicine bottle that 10% mannitol solution is housed is placed on respectively in the freeze-drying pallet of freeze-drying pallet that Partition board frame arranged of the present invention and the no Partition board frame of tradition, platinum electrode (Pt100) with two same-types inserts respectively in two medicine bottles of pallet central part same position then, records in the medicine bottle temperature curve of medicine respectively and see Fig. 3 under same experimental condition.
As shown in Figure 3, sample in the framework of dividing plate is arranged in the pre-freeze process, pre-freeze speed is faster than no dividing plate, and the temperature that reaches in this process low than no dividing plate.In dry run, rate of rise in temperature is faster than no dividing plate, and temperature is than the height of no dividing plate.Proved absolutely the framework that adopts the present invention that dividing plate is arranged, more thoroughly freezing, also can shorten freeze-drying time, improve freeze drying efficient, energy savings.And it is more even to adopt the framework that dividing plate is arranged that all samples is heated, and has guaranteed uniformity of sample.Particularly to the product freeze-drying of temperature requirement harshness, there is the framework of dividing plate can strengthen the controllability of process, improve the quality of product.
Claims (2)
1. the framework of a freeze-drying pallet is characterized in that this framework is made up of the dividing plate (2) and the outside framework all around (1) of centre, and dividing plate (2) is fixing by welding with outside framework (1) wall.
2. the framework of freeze-drying pallet according to claim 1 is characterized in that height, thickness and the length of dividing plate (2) is identical with outside framework (1).
