Counter-Current Rotary Dryers are more suitable for materials that
must be dried to very low levels of moisture, where the last traces
of moisture are difficult to remove, or where an elevated product
temperature is desirable.
They are also used effectively as combined dryer / preheaters.
However, since the final product is in contact with the gas at its
highest temperature the counter-current dryer is often unsuitable
for heat sensitive materials. Although this system can be more
efficient, moisture which is to remain in the product, is not so
readily controlled.
Counter-Current Rotary Dryers Features
