Description

Vacuum one-step method extract dry machine

Technical field

This utility model relates to a kind of vacuum one-step method extract dry machine, belong to technical field of heat exchange, be applicable to that product quality must meet Good Manufacturing Practice and Quality Control of Drug (GMP), and require exsiccant various adhesive Chinese medical concretes, Colla Corii Asini, gelatin and other thermal sensitivity biological product under 40～80 ℃ of cryogenic conditions.

Technical background

Present most Chinese medical concrete is still adopting charging tray formula oven drying, and this drying means be unable to do without a large amount of manually-operateds, and this can bring the artificial pollution that does not obviously meet GMP, and many pharmaceutical factories of traditional Chinese medicine also wish to change the backward state of present extract dry.When viscosity extractum adopted the direct method spray drying, atomizing extractum droplet is thin more to be helped fast more by hot-air dry, but thin droplet easily flies upward to be stained with and adhere on the spraying Tata wall, and more mist drips easily and taken to the tail gas collecting system by hot-air tail gas.Stick on the tower wall extractum and toasted by hot-air for a long time and go bad, stick in the trapping system pipeline and bag hose in extractum can only go recycling again by washing into thin liquid.Direct method spray drying extractum yield is low, causes the pharmaceutical factory of traditional Chinese medicine forbidding to direct method spray drying extractum technology.The extract dry machine is for selecting for use preferably owing to there is not other at present, and it is constant decades to cause Chinese medical concrete to rely on oven drying.Patent 99226912.1 vacuum and low temperature spray granulation machines and 01238832.7 Chinese medical concrete vacuum drying granulator by my application; the complicated cost of former structure is higher, and latter's structure is simpler, but there is deadly defect in the both; structure is difficult to effectively amplify, and powdered extract can not maximize.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming of prior art, for Chinese medicine production provides a kind of drying efficiency that can maximize the high and very high vacuum one-step method extract dry machine of product yield, change present extract dry technology and the too disproportionate situation of requirements of the times Chinese medicine production modernization.

The technical solution of the utility model is: it comprises steam articulation, steam articulation fixed bar, left rotary shaft axle supporting base, driving machine, left and right rotating shaft, cylindrical shell, coagulates water suction tube, flight, inclined chute, pulverizer, heating tube group, the double discharging opening of maintenance, inclined chute stationary pipes, nozzle, cartridge filter, filter, right spindle, the articulation fixed bar of bleeding, be characterized in, left and right sides shaft support is on the Y-axis supporting base, and the certain slope of cylindrical shell centrage is by right spindle axes of rotation skew left; The heating tube group is distributed on the cylinder inboard wall with forms of radiation, each heating tube group two ends and cylindrical shell welding UNICOM; Inclined chute is tilted from left to right, and inclined chute is equipped with the polylith flight by the fastening location of immobilized inclined chute stationary pipes on the cylinder inboard wall directly over the inclined chute inlet; The extractum inlet pipe of band extractum nozzle passes inclined chute stationary pipes center and enters cylindrical shell, and nozzle is arranged in the middle upper part of filter and heating tube group.

Since the axle rotation centerline by certain gradient by right spindle axes of rotation skew left, the heating tube group has been held concurrently and has been copied the extract powder plastochondria and do the effect of warp-wise mechanical fluidisation, the inclined chute incline direction is opposite with the rotation centerline incline direction, the polylith flight that on the overhead cylinder of inclined chute inlet, is equipped with exsiccant hot dipping cream powder body copy into, utilize big potential difference constantly to transfer to right-hand member from left end, right-hand member powder body material level increases and is tilted to the left and radially under the fluidisation combined effect at shaft centre line, force the powder body to move axially left, the extract powder plastochondria that flight and inclined chute are forced to do carries out axial flow and mixed, adopt thick droplet principle to make the droplet alligatoring to guaranteeing that drying process continues to carry out degree, by nozzle the extractum droplet is sprayed on the powdered extract powder body in the fluidisation, the extractum droplet is wrapped up to intercept its viscosity, rapid draing under the vacuum and low temperature heating by the powder body immediately.Its advantage is the drying that can maximize, drying efficiency height, product yield height.
