Abstract
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.
Description
One, technical field
The present invention relates to a kind of be applied to industries such as pharmacy, chemical industry, food, agricultural chemicals pass through spray-drying, mixing granulation and again drying process realize the production technology of granulating.
Two, background technology
At present, the process for granulation that industry such as pharmacy, chemical industry is used comprises spray-drying, mixing granulation and three process such as drying more successively, to in spray-drying, granulating and drying two complete equipments and two different containers, carry out drying, granulation, dry more step by step, it produces big, the inconvenient operation in occupation of land space, labour intensity is higher, production efficiency is lower, is unfavorable for applying.
Three, summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, spray-drying, mixing granulation and dry again three process can be merged the one step process for granulation that concentrates on the spray-fluidized granulating and drying of finishing continuously in the airtight container and provide a kind of.
Purpose of the present invention realizes by following technical solution: a kind of one step process for granulation of spray-fluidized granulating and drying is: at first, spray drying treatment is carried out to liquid principal goods material in top in the hothouse of spray drying device, finishes the seed meal drying of phase I; Then, this seed dry powder vertical sedimentation enters the bottom granulation zone in the hothouse, fluidized bed plant by the hothouse bottom is in the suspension fluidized state with seed dry powder, at this moment, the auxilliary material of another road liquid also is atomized into small droplet by the nozzle atomization device and is sprayed on the seed dry powder that is suspension fluidisation shape, make this seed dry powder cohesion conglomeration and be included in and carry out the granulating and drying processing together, finish the granulating and drying of second stage; Then, the finished powder that granulating and drying makes is discharged from the powder outlet of hothouse bottom, and realize granulating and in charging basket, collecting through strength conveying cooling and the processing of fine powder return mechanism; Dried waste gas by the cyclone separator purification separation after and enter atmosphere, separate the fine powder that obtains by cyclone separator in addition and carry cooling and fine powder return mechanism through strength again and return bottom in the hothouse and participate in again granulating and drying and handle.
After adopting the present invention, (same airtight container) just can merge realization spray-drying, mixing granulation and dry again three process in the hothouse of spray drying device, thereby production link, saving production space, reduction labour intensity in the middle of can reducing, easy and simple to handle feasible, can improve labor protection, and improve granulate quality and operating efficiency, have significant technological progress, meet GMP (GMP) requirement fully, can in the granulation industry, widely popularize application.
Four, description of drawings
The present invention is described in further detail below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the flow chart of the one step process for granulation of spray-fluidized granulating and drying of the present invention.
Five, the specific embodiment
Before process for granulation, need reequip the hothouse and the peripheral facility thereof of spray drying device, make the inside of hothouse be divided into the upper and lower, top is spray drying treatment, is connected with blower fan, filter, heater and charging pump, nozzle atomization device etc.; The bottom is that granulating and drying is handled, and is connected with blower fan, filter, heater, charging pump, nozzle atomization device (another set of) and fluidized bed plant (having granulation, agitating function) etc.
With reference to Fig. 1 as can be known, the one step process for granulation of spray-fluidized granulating and drying of the present invention is: at first, top in the hothouse of spray drying device to liquid principal goods material (for major ingredient) to carry out spray drying treatment (be that air is heated into hot blast by blower fan, filter, heater and enters hothouse top, simultaneously liquid principal goods material is dispersed into droplet through charging pump, nozzle atomization device and contacts with hot blast in hothouse), finish the seed meal drying of phase I; Then, this seed dry powder vertical sedimentation (descending and the stream mode for vertical) enters the bottom granulation zone in the hothouse, fluidized bed plant by the hothouse bottom is in the suspension fluidized state with seed dry powder, at this moment, it (is auxiliary material that another road liquid is assisted material, wet adhesive or dressing material etc.) also be atomized into small droplet and be sprayed on the seed dry powder that is suspension fluidisation shape by nozzle atomization device (another set of), make this seed dry powder cohesion conglomeration and be included in and carry out granulating and drying processing (and contacting with the hot blast that enters the hothouse bottom once more) together, finish the granulating and drying of second stage; Then, the finished powder that granulating and drying makes is discharged from the powder outlet of hothouse bottom, and realize granulating and in charging basket, collecting through strength conveying cooling and the processing of fine powder return mechanism; Dried waste gas by cyclone separator (genus air exhausting device) purification separation after and enter atmosphere, separate by cyclone separator (genus air exhausting device) that the fine powder that obtains is carried cooling and fine powder return mechanism through strength more in addition and the bottom returned hothouse in participates in the granulating and drying processing again.Wherein strength carry cooling and fine powder return mechanism be utilize dry, the air of purification, temperature adjustment effectively cools off to realize granulating the finished powder of discharging from the granulation zone of hothouse bottom and collects in charging basket; In addition, also the fine powder that separate to obtain from cyclone separator is returned again and be transported to the hothouse bottom and participate in granulating and drying again.Simultaneously, it is double again does a cold wind and uses, and can alleviate " general top " phenomenon at hothouse top.The top of hothouse, the hot blast temperature of bottom are not quite similar.
The present invention can be provided with clamping device (having blower fan) on the top in locular wall, the chamber of above-mentioned hothouse, handle with locular wall, the cooling of chamber jacking row natural wind hothouse, can effectively reduce the temperature on locular wall, chamber top, the material that helps improving low softening point is adsorbed on " fusion " phenomenon that produces on the locular wall.Can also on the cone of the bottom of above-mentioned hothouse bearing be set, carry out artificial rapping with the locular wall to hothouse and handle, can shake falls to being adsorbed on accumulation material on the locular wall.
