Description
Technical field
The present invention relates to dry materials technical fields, more particularly to be suitably applied the extract of active ingredients from traditional Chinese medicinal
Extract the method and device of the high-efficiency and continuous drying of the drying in concentration flow path.
Background technology
In pharmacy, food and chemical field, need water remaining in material after drying steps remove concentration or other
Wet part.
In pharmaceutical production technique at this stage, the widely used drying means of drying section has spray drying process, true
Empty seasoning, equipment have spray drying tower, vacuum drying chamber, vacuum crawler formula drying machine etc..All kinds of corrupt practices creep in for these equipment,
Such as：
Spray drying tower：It can only be dried under normal pressure, temperature when dry is higher, and the heat-sensitive substance in drug holds
Easy in inactivation.Powder rate is obtained after drying and only has 70%, and waste is more serious.The thermal efficiency is relatively low (generally 30%~40%), steam or
Power consumption is larger.Volume is larger, takes up an area more.
Vacuum drying chamber：Higher concentrate concentration is needed, industrial production poor continuity, drying efficiency is low, general to dry
Time was at 10 hours or more.Long time drying is easy to damage the active ingredient in material.The explosive payload of pallet is less, once powder charge
More than 1/3 height of pallet, material is easy for splashing out amount when dry, causes to waste.
Vacuum crawler formula drying machine：Equipment is long, needs great floor space.Equipment Chinese style multilayer crawler-belt-type structure,
It cleans extremely difficult.
Chinese invention patent Authorization Notice No. CN105477893B discloses a kind of continous way high concentration liquid sterilizing concentration
Drying device and method can make material reach bacterium inspection while being concentrated and dried and require, jacket type one-pipe heater therein
Inner and outer tubes between be filled with heating fluid medium, material (concentrate or extracting solution) is passed through in inner tube, makes object
Material is heated by the heating fluid medium in outer tube, and is completely in liquid phase state, and secondary heater continues to add to material
Heat, it is required that retention time of the material in jacket type one-pipe heater and secondary heater at high temperature sufficiently achieves sterilizing
Condition, since a point of secondary heater, in the state of vacuum, evaporative effect, original material takes place in material
It is divided into the liquid and vapor of film-form, evaporator makes material be evaporated to be condensed into cream block or powder, and vacuum desiccator is by material
Flattening-out is further to evaporate its moisture.The patent is actually to be combined together vacuum drying with sterilizing, is realized primary dense
The continuous sterilization and drying of contracting liquid or extracting solution.But the vacuum degree between the certain point of its secondary heater and evaporator is one
It causes, there are the following problems for such mode：The first, evaporate vacuum degree it is certain in the case of, material secondary heater with
Before the consistent point of evaporator vacuum degree, the pressure range reached in materail tube is limited, is unfavorable for different material evaporation
The evaporation of characteristic has its limitation；Second, the vacuum degree between some point and evaporator of secondary heater is consistent
After point, the variation of vacuum degree is approximately linear, volume change, and approximation line is unfavorable for diffusion of the material in discharge port, more substantially
Long-pending dry cream, center material do not flash fully.
In addition the temperature of charge and the temperature of charge of secondary heater out for entering vaporization chamber are consistent, such mode
There are the following problems：The first, before material does not enter vaporization chamber, pressure is in approximately linear, material evaporation temperature, also approximately linear,
The evaporative effect of material is shallower, is unfavorable for the moisture diffusion of material evaporation；The second, from material feeding temperature to drop temperature,
In the case that vacuum is certain, difference is certain, when evaporation capacity ratio increases, can only only increase its secondary heater face accordingly
Product, has its tool sex-limited.
