Chemac equipments offers fluid bed dryers. The atmospheric air is sucked in the dryer through 5/10-micron filter by an efficient dynamically balanced fan driven by an electric motor. The clean air then passes over the electric heaters/ steam or oil radiator provided with temperature controller. The hot air passes through the produce and fluidisation dries the product. Dryer is provided with dehumidifier [chilled water system] at the inlet of the dryer so as to dry the product at low temperature under fluidized condition. The blower speed is controlled by ac frequency drive so as to control the fluidisation avoiding choking of the filter bag. A raking system provided to avoid lump formation in the container to achieve uniform fluidisation and uniform drying. A model with complete automation and plc, automatic bag shaking and with mimic is also offered.
