| 20100223804 | Air modulating non-thermal dryer - An air modulating non-thermal dryer (AMND) system that de-waters a wet feedstock stream with an ambient airstream, to produce a dried product stream. The system utilizes a drying chamber in the efficient production of a dried product, and includes an acoustic induced air motion liberation or “SONICATION™” of the moisture with a combination of drivers, labyrinth transmission lines, and air modulating devices. Initially, a 50% to 60% dry composite of biomass or biosolids is pneumatically conveyed to the chamber through an in-line cutter and a swiveling load leveler with an atomizing nozzle for final shredding. The system can liberate up to 90% of the moisture content, using high volumes of process air, along with infeed motive air to deliver wet feedstock material into the chamber. Expelled airborne moisture may be discharged to atmosphere, without further processing, or it may be recaptured for potable uses. | 09-09-2010 |
| 20130199053 | METHOD FOR REMOVING MOISTURE FROM A CONTAINER - A system for microbially deactivating articles, such as medical, dental, veterinary and mortuary instruments and devices. The system includes vibration means for producing ultrasonic waves to facilitate drying after the completion of a liquid microbial deactivation process. | 08-08-2013 |
| 20130298419 | CLEARING PRECIPITATION - A method of clearing precipitation from a surface of a window comprises ultrasonically vaporizing the precipitation. A vehicle windscreen, for example, has transducers distributed around the edge and bonded to the windscreen to insonify it. The transducers are energized by a drive system. | 11-14-2013 |
| 20140150284 | ACOUSTIC DRYING SYSTEM WITH INTERSPERSED EXHAUST CHANNELS - An acoustic air impingement drying system is provided for drying a material. An inlet chamber receives air from an airflow source provides air at a supply flow rate. A plurality of acoustic resonant chambers are provided, 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. A plurality of exhaust air channels interspersed between the outlet slots remove the air directed onto the material by the acoustic resonant chambers. A blower pulls air through the exhaust air channels at an exhaust flow rate. | 06-05-2014 |
| 20140150285 | ACOUSTIC DRYING SYSTEM WITH PERIPHERAL EXHAUST CHANNEL - An acoustic air impingement drying system is provided for drying a material using a pneumatic transducer unit. An inlet chamber receives air from an airflow source at a supply flow rate. A plurality of acoustic resonant chambers are arranged in a drying zone, each having an inlet slot that receives air from the inlet chamber and an outlet slot that directs air onto the material, the outlet slots being oriented at an oblique angle relative to a width dimension of the pneumatic transducer unit. One or more peripheral exhaust air channels are arranged around the outer boundary of the drying zone for removing the air directed onto the material by the acoustic resonant chambers. A blower pulls air through the exhaust air channels at an exhaust flow rate. | 06-05-2014 |
| 20140202021 | ACOUSTIC WAVE DRYING SYSTEM - 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. One or more secondary closed-end resonant chambers are formed into side surfaces of the primary air channel. An air impingement airstream containing acoustic energy exits the air outlet and impinges on the material. | 07-24-2014 |
| 20140202022 | ACOUSTIC DRYING SYSTEM WITH SOUND OUTLET CHANNEL - 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. | 07-24-2014 |
