Description
Technical field
The invention belongs to solid pharmaceutical preparation field, it is related to a kind of vertical discharging apparatus, more particularly to a kind of fluid bed vertically goes out
Expect device.
Background technology
It is that the flowable materials such as granular, paste are placed on into the air such as porous plate point that material, which is dried, using fluid bed
On fabric swatch, the dried medium with suitable speed is sent into by its underpart.When velocity of medium is relatively low, gas flows between material particles
Cross, it is whole material bed motionless；Gradually increase air velocity, the bed of material starts gap between expansion, particle and increased；Increase gas velocity again
Degree, considerable part material is in suspension, forms gas-solid mixed bed, i.e. fluid bed, because the material suspended in fluid bed is such as boiling
The liquid risen, therefore also known as ebullated bed, and the property of fluid is presented in it in many aspects, for example, there is significantly upper interface, and protects
Water holding is put down；If increasing air-flow velocity again, particle almost all is entrained by the flow of air, and is just changed into gas and be delivered.Therefore, air velocity
It is fluidized bed drying most basic governing factor, suitable air velocity should be between making the bed of material start in fluidization and by material web
Between going out.
Fluidized bed granulation method is the fluidized state for keeping under the airflow function for making drug powder from bottom to top suspending, bonding
Agent liquid sprays into the method for making powder be agglomerated into particle into fluidising chamber from top or bottom.
Fluidized bed prilling is also referred to as boiling granulating or one-step palletizing, is once to put into material in closed container,
Material is subjected to uniformly mixing in container, by equipment sprayed into adhesive average rate again, allows adhesive fully to be mixed with material
Close, flowed in container, form little particle, hot blast is sent into by bottom, wet granular can be dried, finally directly collect
The technology of finished product dry particl
Typically using air as fluidizing gas, after first being preheated, the fluidized-bed bottom with distribution grid is passed to, makes to need granulation
Solid powder in fluidisation state.Most of liquid feedstock is to spray into fluid bed by two-fluid spray nozzle, it is desirable to which nozzle has operation bullet
Property and be not easily blocked, if hot gas, atomization crystal solution when more it is noted that.In order that the liquid that must be coated on particle is as far as possible
Dry, it is general using gas and solid particle adverse current, to make Granularity Distribution evenly.The speed of fluidizing gas will be arrived greatly
Bulky grain strong movements can be made, to prevent caking phenomenon.
A large amount of solid particles are suspended among the fluid of motion, so that particle has some appearance features of fluid,
When air passes through the bed of material of the random occupied state of solid particle from bottom to up, and air velocity meets or exceeds the critical of particle
During fluidizing velocity, particle in seething up and down in the bed of material, and has partial particulate to be less easily entrained by out the state of the bed of material, and this stream is affixed
Tactile state is referred to as fluidization of solid, i.e. fluid bed.
At present, lateral discharging structure is mostly used for solid pharmaceutical preparation fluid bed, however, long-term production practices show,
It is long that this lateral discharging structure there are discharging time, and discharging not exclusively or is not easy many technical problems such as clean, it would be highly desirable to
It is resolved.
