Acoustic drying system with sound outlet channel
First Claim
1. An acoustic wave drying system for drying a material, comprising:
- an airflow source;
an acoustic resonant chamber that directs acoustic energy onto the material, including;
an air inlet for receiving air from the airflow source;
an air outlet;
a primary air channel having side surfaces connecting the air inlet and the air outlet, the primary air channel having a primary air channel length between the air inlet and the air outlet;
a closed-end resonant chamber formed into a first side surface of the primary air channel, the closed-end resonant chamber having side surfaces and a resonant chamber length; and
a sound air channel having a sound air channel inlet on a second side surface of the primary air channel opposite to the closed-end resonant chamber and a sound air channel outlet for directing an air impingement airstream containing acoustic energy onto the material, the material being spaced apart from the sound air channel outlet by a gap distance, the sound air channel having a sound air channel length between the sound air channel inlet and the sound air channel outlet;
wherein a first fraction of the air received from the airflow source is directed out of the pneumatic transducer through the air outlet and a second fraction of the air received from the airflow source is directed out of the pneumatic transducer through the sound air channel outlet as the air impingement airstream.

Abstract
An acoustic wave drying system for drying a material using an acoustic resonant chamber that imparts acoustic energy to transiting air received from an airflow source. The acoustic resonant chamber includes a primary air channel having side surfaces connecting an air inlet and an air outlet, the primary air channel having a primary air channel length between the air inlet and the air outlet. A closed-end resonant chamber is formed into a first side surface of the primary air channel, the closed-end resonant chamber having a resonant chamber length. The acoustic resonant chamber also includes a sound air channel having a sound air channel inlet on a second side surface of the primary air channel opposite to the closed-end resonant chamber and a sound air channel outlet for directing an air impingement airstream containing acoustic energy onto the material.
