Acoustic drying system with interspersed exhaust channels

An acoustic air impingement drying system for drying a material, comprising:

• an airflow source providing air at a supply flow rate;
• a pneumatic transducer unit having a width dimension that spans a width of the material including:
• an inlet chamber that receives air from the airflow source
• a plurality of acoustic resonant chambers, each having an inlet slot that receives air from the inlet chamber and an outlet slot that directs air onto the material, wherein the acoustic resonant chambers impart acoustic energy to the transiting air, the outlet slots being oriented at an oblique angle relative to the width dimension of the pneumatic transducer unit;
• and
• a plurality of exhaust air channels interspersed between at least some of the outlet slots for removing the air directed onto the material by the acoustic resonant chambers;
• and
• a blower for pulling air through the exhaust air channels at an exhaust flow rate.
