Technique for producing grain with one-step method containing atomization, fluidization, granulation and dessication

InactiveCN101274243AMeet the requirements of Good Manufacturing Practice (GMP)Reduce intermediate production linksMaterial granulationEngineeringSpray drying
The invention discloses a one-step method granulation production technique of spray-fluidization granulation dryness, which is characterized in that: firstly, the sponging drying disposal of liquid main material is carried out at the upper part in a spraying drying chamber to complete the drying of seed powders; subsequently, the seed dry powder is vertically deposited in a lower granulation area in the drying chamber and is arranged in a suspended fluidization state by a fluidized bed device when another way of liquid auxiliary material is also atomized as fine droplets and sprayed on the seed dry powder to carry out the granulation drying disposal together and complete the granulation drying; subsequently, the product powder prepared by the granulation drying is exhausted and the granulation is realized by the disposal of a pneumatic delivery cooling and fine powder returning device and is collected in a material bucket; furthermore, the fine powder obtained by the separation of a cyclone separator is returned to the lower part of the drying chamber by the pneumatic delivery cooling and fine powder returning device so as to participate the re-granulation drying disposal. The invention reduces the middle production links, saves the production space, reduces the labour intensity, improves the granulation quality and the working efficiency, and can be widely generalized and applied in granulation industries.

Gentiopicroside drop pill and preparation method thereof

InactiveCN101053571ASignificantly protects the liver and promotes choleresisIncrease or improve solubilityOrganic active ingredientsDigestive systemSolubilityCentrifugation
A gentiopicroside dropping pill contains gentiopicroside and medicinal groundsubstance components with a dosage proportion by weight of 1:0.5-10. The format of the gentiopicroside dropping pills is 5-500mg/grain. The preparation method of the gentiopicroside dropping pills comprises the following steps: refluxing the gentian coarse powder with ethyl hydrate for extracting, combining and concentrating the extract, standing it overnight at low temperature; performing soup centrifugation and filtration; eluting the filtrate with macroporous resin column; collecting the eluent, concentrating it at reduced pressure to concrete shape, vacuum (freeze) drying it to obtain a crude product; refining it to obtain pure gentiopicroside; selecting medicinal groundsubstances for preparing solid dispersion as a carrier and suspending gentiopicroside in the melting carrier, and then working out gentiopicroside dropping pills by adopting the dropping method. The gentiopicroside dropping pills, as gentiopicroside dropping pill dose, possesses remarkable liver-protection and cholagogic functions. Since the medicament is highly dispersed molecularly in the groundsubstance, and the groundsubstance with water-solubility can accelerate dissolution velocity and absorption rate of drugs, then the bioavailability is high.
