Description
Technical field
It is the utility model relates to dry materials technical field, in particular to a kind of for pharmacy, food and chemical field
The high-efficiency and continuous drying device of improvement, the device are suitably applied the drying rank of active ingredients from traditional Chinese medicinal extracted in concentration flow path
Section.
Background technique
In pharmacy, food and chemical field, need water remaining in material after drying steps remove concentration or other
Wet part.There are spray drying tower, vacuum oven, vacuum crawler formula dry in the widely used drying equipment of drying section at present
Dry machine etc., all kinds of corrupt practices creep in for these equipment, such as:
Spray drying tower: can only be dried under normal pressure, and 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%, is wasted more serious.The thermal efficiency is lower (generally 30%~40%), steam or
Power consumption is larger.Volume is larger simultaneously, takes up an area more.
Vacuum oven: needing higher concentrate concentration, and industrial production poor continuity can only singly criticize drying, dry effect
Rate is low, and general drying time was at 10 hours or more.Long time drying is easy to damage the effective component in material.Besides pallet
Explosive payload is less, once explosive payload is more than 1/3 height of pallet, material is easy for splashing when dry, causes to waste.
Vacuum crawler formula drying machine: equipment size is larger, longer, needs great occupied area.Equipment barrel is multilayer
Track structure, changing batch cleaning is difficulty, and it is thorough to be difficult cleaning.
Utility model content
At a certain temperature, the wet stock of any aqueous (or other wet parts, for aqueous, similarly hereinafter) has certain steaming
Vapour pressure, when this vapour pressure is greater than the water vapor partial pressure in ambient gas, moisture will be vaporized.With the progress of evaporation, material contains
Water and steam drops, the water vapor partial pressure in pipeline inner periphery gas can be gradually increased, and the rate of evaporation also can be slower and slower,
The moisture vapor contained by the material is equal with the water vapor partial pressure in gas, and system reaches flat city, and evaporation will not continue to carry out.
For this purpose, the purpose of this utility model is that providing one kind for deficiency present in existing dry materials technology and changing
Good high-efficiency and continuous drying device.The device aims to solve the problem that the defect of traditional drying equipment, and reducing water vapor partial pressure bring influences,
Dry efficiency is improved, residual is reduced, reduces installation space, the continuity of production is kept, shortens the heated time of material, is realized
Low concentration charging, is continuously available the stable dried material of greater homogeneity.
To achieve the goals above, technical solution used by the utility model is as follows:
A kind of high-efficiency and continuous drying device of improvement includes the heater more than two-stage that is used in series, every grade of heater
Material circulation latus rectum amplify step by step, the logistics of upper level heater circulation latus rectum is that the logistics of next stage heater circulates latus rectum
1~5 times.
It further include a vaporization chamber, a condenser system and vacuum system, institute in a preferred embodiment of the utility model
It states and is provided with material and saturated vapor two-phase mixture entrance, saturated vapor outlet, dried material outlet on vaporization chamber, it is described cold
A saturated vapor entrance, vacuum orifice and condensate discharge mouth, material and saturation on the vaporization chamber are provided in solidifying system
Material and the outlet of saturated vapor two-phase mixture on steam two-phase mixture entrance and afterbody heater are connected by pipeline
It connects, the saturated vapor outlet on the vaporization chamber is connected to by pipeline with the saturated vapor entrance in condenser system, the evaporation
Dried material outlet on room is connect with dried material collection system, and the vacuum orifice in the condenser system and vacuum system connect
It connects, the condensate drainage mouth in the condenser system is connect with condensate collection system.
Due to using technical solution as above, the utility model passes through the artificial water vapor partial pressure by ambient enviroment again
It reduces, to reduce the decaying of evaporation rate, ensure that going on smoothly for evaporation.
Mutually synthermal heating agent or different temperatures can be used in the heat exchanger that the utility model multistage is incremented by logistics circulation latus rectum
Heating agent, can be more preferably using the heating agent effect of different temperatures.Moisture content is high when material is in upper level heat exchanger, therefore upper one
Grade heat exchanger uses the higher heating agent of temperature, such as: industrial steam, superheated water ... etc., heating agent and material are in opposite
Biggish heat transfer temperature difference, the hygroscopic water evaporation rate in material is high at this time, and in the higher situation of material moisture, the heat of absorption
Amount is mainly used for the evaporation of moisture, and the bulk temperature of material is not too high, therefore will not generate to the effective component in material broken
It is bad.The heat exchanger of next stage uses the lower heating agent of temperature, such as: at negative pressure steam, hot water ... etc., heating agent and material
In relatively small heat transfer temperature difference, the water content in material already declines at this time, and material occupies biggish specific gravity, using temperature compared with
Low heating agent will not make the bulk temperature of material excessively high, can effectively avoid the effective component in material from being destroyed.
Compared to other drying equipments, the utility model has the advantage that continuity of production process is strong, high production efficiency,
Material heated time is short, and material is heated evenly, and product quality is uniform, and entire drying process carries out under vacuum, in material
Effective component saves preferably, and device structure is compact, and the installation space needed is small.
