Product Description

GFG series batch type fluid bed dryer is designed based on GMP standard and is known for its enhanced drying capacity and sanitary operation condition.This design is mainly used to dry non-fragile granules and powder materials in foodstuff, pharmaceutical and chemical industry. 

After being heated and filtered, clean hot air is introduced into the air distributor at the bottom of the dryer and flow through a perforated drying bowl on which wet materials are loaded. Under the effect of strong air stream and rotating agitator, wet materials are perfectly fluidized. Moisture evaporates very fast because of thorough contact and heat transfer between hot air and wet material. At the top of the dryer, bag filter is installed to separate fine particles from the exhausted damp air. 



Technical Features 

1) Robust drying chamber: The drying chamber is made by SUS304 or SUS316L steel plate, fully welded and mirror polished. The design is robust, simple and compact which requires minimum maintenance. 

2) Fast and uniform drying: Due to the specially designed drying bowl and agitator, wet material can be perfectly fluidized to make sure fast and uniform drying. 

3) Flexibility in heat source: The heat source can be steam, hot water, electricity, thermal oil, oil/gas/coal/biomass fired hot air generator to match with different working conditions. 

4) Flexibility in drying: The dryer works in batch type so that drying time can be easily controlled. It can be used to dry materials with different moisture content and moisture type. 

5) GMP design: The drying chamber is fully welded, mirror polished without dead corners for cleaning to meet GMP standard.
