Traditional drying apparatus requires several pre-treatment stages before drying. Screening removes larger particles, while smaller particles are separated by a centrifugal device; this is to prepare the liquid waste for the condensing stage. The pre-treated liquid is then concentrated down to some 20%, which is then dried by mixing with other dried powder. As an alternative, another method to dry the liquid waste by injecting hot air from the top of the incinerator. This method was not cost-effective, however, owing to the further treatment required for waste vapor and strong smells.

The Okadora Dryer requires no such pre-treatment. The process is as simple as loading and drying. The comparison in performance between the Okadora Dryer and traditional dryers is easily made: the Okadora Dryer outstrips traditional dryers in terms of installation costs, running costs, site space and ease of operation.
