Overview
Hot air through a round bed
The GFG fluid bed dryer dries damp granules and powder. Filtered, heated air enters from the bottom of the dryer and lifts the material into a fluidized state, so water evaporates quickly.
The main parts are the air filter, heater, main machine, trolley, dust removing chamber, pipe, fan and silencer.
Charge
Put granules or powder into the charging hopper.
Fluidize
Air is filtered and heated, then passes through the Dutch sieve. The material fluidizes under stirring and negative pressure, and dries.
Collect
The fan draws moist air through the dedust bags. Fine powder stays in the bags and is shaken back into the container.

Features
Made for easy cleaning and even drying
The dryer follows GMP design and works under negative pressure.
Round fluid bed
The inside is smooth with no dead corner, and very easy to clean.
More fluidized area
The main machine is 20% higher than a common design. Fluidized height is kept and the bag filter carries less load.
Complete dust removal
Two air cylinders change over alternately. The anti-static filter bag stops material sticking.
Stirring device
Stirring avoids lumps and channel flow in damp material.
Negative pressure
The dryer runs under negative pressure, is easy to clean, takes up little floor space and conforms to GMP.
Pairs with granulation
It is used with the YK swing granulator and the GHL high speed mixing granulator.

Questions
Before you order
What are fluidized bed dryers?
They are dryers that lift damp granules or powder on a stream of heated air, so water evaporates quickly. The GFG is a round one, with batch charging of 60 kg to 500 kg across six models.
How does a fluid bed dryer work?
Filtered, heated air enters from the bottom and passes through the Dutch sieve. The material fluidizes under stirring and negative pressure and dries. The fan draws the moist air through the dedust bags, and fine powder stays in the bags and is shaken back into the container.
What is the purpose of a fluidized bed?
To dry damp granules and powder evenly and quickly. In the GFG the stirring device avoids lumps and channel flow, and operating temperature is controllable up to about 120 °C.
What are the advantages of a fluidized bed dryer?
The GFG follows GMP design, works under negative pressure, is smooth inside with no dead corner and is easy to clean. It takes up little floor space, and complete dust removal uses an anti-static filter bag so material does not stick.
