Using carrier air, the traditional dryer used to give off huge amounts of calories, thus causing a lowering of temperature inside the dryer. Consequently its drying efficiency was drastically reduced. The Okadora dryer, on the other hand, operates under high efficiency and with little loss of energy.
The Okadora dryer operates at a heating speed four times higher than a traditional dryer. This means that ingredients for drying are given calories at four times the speed of traditional dryers. It is for this reason that the Okadora dryer can be so greatly reduced in size.
Due to a combination of centrifugal force and the thin filming layer on the heat-transmitting panel, material with a higher water content is naturally conducted faster to the panel and through evaporation loses its gravity. After evaporation, this material is replaced by material with higher water content and so on. This cyclical action makes it possible for evaporation to take place until the material has an even and low water content. On the contrary, with a traditional dryer, which is of the horizontal type, the lower part of the container tends to fill up with the material and the stirring paddle cannot move the heated ingredient evenly. It is therefore clear that the horizontal dryer takes a much longer time to lower the water content of the material.
