PGL-B Spray Drying Granulator (Fluid Bed)
applications:
Pharmaceutical industry: tablet, capsule granule, granule of Chinese medicine with on or low sugar
Foodstuff; cocoa, coffee, milk powder, juice of granule, flavoring and so on.
Other industries: pesticides, feed, chemical fertilizer, pigment, dyestuff and so on.
features:
Integrate spraying, drying fluid granulating in one body to realize granulating from liquid in one step.
Using the process of spraying, it is particularly suitable for micro auxiliary raw materials and heat sensitive raw materials. Its efficiency is 1-2 times that FL boiling granulating machine.
The final moisture of some products can reach 0.1%. It is equipped with powder returning device. The rate of granule forming is more than 85% with 0.2-2mm of diameter.
The improved inner roller multi-flow atomizer can treat the liquid extract with 1.3g/cm3 of gravity.

Example of model choice: Suppose that are 120kg liquid extract I (include 30% solid) and 60kg seed II in one vessel, from I and II, we can get theoretical product amount M=mI+mII=120kg×30%+60kg=96kg, working time T=120kg/30kg/h=4h, from the parameter table we can find that the fluidization amount is inside the standard loading range. If we require two batches in one duty time, model PGL-30B is OK.
