The traditional drying apparatus uses ‘carrier air’ to conduct evaporated air to the condenser. Consequently, ‘carrier air’ produces waste gas (containing odours) in large volumes, which is emitted into the atmosphere. On the contrary, the Okadora Dryer does not need ‘carrier air’ at all and processes evaporated steam into condensed water without any waste gas.

Using, as it does, a large volume of ‘carrier air’ during its operation, the traditional dryer requires a large-scale dust-collection apparatus, because waste gas containing a powdery dust must be filtered before emission. In addition, condensed water, contaminated with powdery dust, is discharged as taint water. The Okadora Dryer, on the other hand, as we mentioned before, does not employ any ‘carrier air’ therefore there is no dust contamination and the condensed water can be discharged without any problems of pollution.
