Why TORBED?

The TORBED produces consistent high quality product with little or no waste, no after taste and oil free.

Hot air is fully recyled within the process chamber that results in a highly energy efficient system.

TORBED TECHNOLOGY: Principal of Operation

The TORBED provides a novel method of processing particles of any shape in a gas stream which is normally hot air. A well defined fluidised packed bed of raw material is floated over the blades and supported by the momentum of linear jets of process air. The blade arrangement guides the process air flow at an angle to create a horizontal motion of the bed. The underside of the bed is exposed to the high velocity impact of the gas stream leaving the blades and is quickly dissipated within the bed depth.

This creates a gently rotating bed of material which is continually mixing with the hot air passing through the bed. This principal dramatically increases the heat transfer rate in the process creating a homogeneous treatment of the product.

If the underside of the bed were the only part to be exposed to these conditions, the processing of the material would be uneven. It was found that causing the bed to flow in a toroidal (doughnut shaped) manner, all the bed material is exposed to the same conditions that exist at the base of the bed.
