are based on the principle of the vibrating fluid bed.
The material is transported on a perforated surface and held in suspension by an air flow and the vibrations of the surface.
The system is suitable for the crystallization and drying of PET granules or flakes from the washing lines.
The residence time is very small (less than 15’).
The air heating can be done with electric heaters, natural gas heaters, diathermal-oil or vapor heat exchanger.
Equipped with am high-efficiency fan with variable flow.
The partial recycling of the air used in the drying pro- cess for energy saving.
The control with a Siemens PLC allows an easy operation in every working phase.
