Rotary dryer air flow

Rotary dryer air flow

An experimental rotary dryer designed with concurrent flow system comprising two primary parts, a double cylinder and a discharge cover, is shown in Fig. 12.1.Forward movement of paddy takes place by inclination angle and rotary motion of the cylinder, while air is blown through the cylinder by the suction fan located on top of the discharge cover

    Heat of compression rotary drum dryers

    The heatless desiccant dryer is the most expensive to operate as 15-20% of its rated flow capacity is consumed as purge air. The rotary drum dryer can lead to significant energy savings because of its unique design and controls. Even compared to a blower purge dryer, rotary drum dryers can save up to 50% of the lifecycle cost. Maintenance cost
