    • 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.
    • 一种声波干燥系统,用于使用声学谐振室来干燥材料,所述声学谐振室将声能传递到从气流源接收的空气。 声谐振腔包括具有连接空气入口和空气出口的侧表面的主空气通道,一次空气通道在进气口和空气出口之间具有一次空气通道长度。 封闭端谐振室形成在主空气通道的第一侧表面中,封闭端谐振室具有谐振室长度。 声学谐振室还包括声空气通道,该声音空气通道在与空气封闭端谐振室相反的主空气通道的第二侧表面上具有声音空气通道入口,以及声音空气通道出口,用于将包含声能的空气冲击气流引导到 材料。
