They are essentially vibratory conveyors with perforated bottom plates. Ambient, cooled or heated air is passed through the holes in the plates under pressure and cools (or heats) the product as it is conveyed.
The air is passed through the unit at a velocity that will support the weight of the particles which creates a fluidised state in the bulk material.
Vibratory fluidised bed coolers have the following advantages:
Provide a reliable and continuous temperature transfer through the unit.
Can handle a wide variety of product types and particle sizes.
The mechanical vibration helps to mix the material to ensure a uniform heat transfer.
They can process fragile materials with soft vibratory movement.
Material is continuously mixed while cooling which reduces the concentration of hot spots.
Access to the trough is easy and allows an easy access for cleaning.
Allow the option for product dust removal or additive inclusion during the heat transfer process.
The conveying velocity of the product can be electronically controlled via variable speed drive to provide the most efficient output.
