FG boiling drying machine is a kind of drying equipment, also known as fluidized bed, is one of the equipment of solid preparation production process used widely in pharmaceutical industry. It has many functions such as mixing and drying. It is generally composed of heater, boiling bed host, cyclone separator, cloth bag dust collector, induced draft fan and operation table. According to the different nature of the material, the cyclone separator or bag dust collector can be selected as needed. The boiling in the drying machine is the use of air heated by the heat exchanger, the formation of a heat network through the smoke plate distribution into the main machine, wet material from the feeder into the dryer, due to the effect of wind pressure, the material in the operating machine to form a boiling state, and with the hot air for extensive contact, so as to complete the material drying in a short time.
The clean heat network is distributed into the bed through the valve plate, and the wet material entering from the feeder is heated to form a boiling state. Due to the extensive contact between the hot air and the material, the heat transfer and mass transfer process is enhanced, so it can be dried in a short time, entering from one end of the bed, after tens of seconds to a few minutes of full drying, and automatically flowing out from the other end of the bed, the equipment generally carries out negative pressure operation.
Where is the use effect of fg boiling dryer good, here is what you want to know
1, the degree of fluidization is high, the material is heated evenly, the heat exchange is sufficient, and the drying strength is large.
2. It broadens the application range of ordinary fluidized bed, and can be applied to high water content powder materials or materials with agglomeration tendency and uneven particle size.
3. It can operate at a small operating gas speed, and the minimum gas speed is only 25% to 30% of the ordinary fluidized bed, so there is less dust entrainment and low requirements for post-processing equipment.
4. Material container adopts cylinder jacking, reliable sealing and easy operation.
5, sealed operation, no dust flying
6, the fluidized bed is a circular structure to avoid dead corners,
7. The hopper is set up to stir to avoid the formation of gully flow when wet materials are reunited and dried.
8, the use of turning over the grain, convenient and rapid *, can also be designed according to the requirements of automatic feed in and out system,
9. Sealed negative pressure operation, air flow is filtered. Easy to operate, easy to clean, is in line with the "GMP" requirements of the ideal equipment.
10, the drying speed is fast, the temperature is symmetrical, each batch of drying time is generally 20-30 minutes.
