Description
Technical field
The present invention relates to a kind of heat drying apparatus, more particularly to a kind of heat drying apparatus for freeze-drier of spraying.
Background technology
In traditional freeze drying process, as shown in Figure 1, it is necessary to will treat lyophilized liquid A be filled into advance vial or
In the container Bs such as pallet, then the container B is contained in the upper glaciations of flaggy C of plane placement, flaggy heats up pair under vacuum environment
Ice cube heats, and steam sublimation simultaneously leaves dry matter.In this drying process, material to be dried is to stand all the time, only bottom
Portion small range region contacts with flaggy, and heat transfer is limited, particularly when material is previously charged into the container of the hot non-conductor such as vial
In when carrying out lyophilized, heat-transfer effect is poor, drying time length；The material upper surface of standing is dried at first, and drying layer is gradually to freezing
Layer declines, and in this stage, drying layer turns into frozen crust distillation obstruction of the vapor to external diffusion, and mass transfer effect is poor, further
Extend drying time；In addition, static drying it is also proposed very high requirement to flaggy temperature homogeneity.
There is a kind of dynamic freeze drying plant later, the material for being frozen into ice particle in advance is placed in cone drier by it
In, using the agitator turning over materials of rotation driving, the cone drier is by boring wall heat drying material.Agitator stirs pair
Material applies mechanical force, and it rubs, collision effect is easily destroyed the original body state of material；And material is necessary in cone
Being stacked into certain altitude can be stirred by agitator, and this accumulation also hinders bottom distillation vapor to external diffusion；In addition, taper
Drier can only be dried by several times.
In summary, the rate of drying of material in freeze-drying how is improved, improves the heat and mass effect during this
Fruit, and the original body state of material how is avoided damage in the drying process, how freeze-drying is carried out continuously, turned into
Those skilled in the art urgent problems to be solved.
