The partial or full dehydration of organic or inorganic matter containing water by induction of matter into a vacuum and processing matter through a specially designed acceleration channel is disclosed. The inducted matter accelerates in air from zero speed to sub-sonic speed to reach supersonic speed. As the material transitions the sound barrier, it is subject to acoustic shock waves and an instant negative pressure drop occurs. The sound waves disintegrate, disinfect the material and extract part or all moisture from any organic or inorganic material.

The present invention discloses a high-moisture sludge ultra-fine synchronizing deep-drying device and a method thereof. The device has a sludge ultrafine pulverizing unit and a sludge drying unit arranged horizontally in parallel, and a pulverized sludge discharge port arranged between them. The sludge ultrafine pulverizing unit comprises a sludge pulverizing chamber and a sludge feeding port, and the sludge pulverizing chamber is a hollow cylindrical structure with a pulverizing rotation shaft arranged in the center, and the pulverizing rotation shaft is provided with a sludge pulverizing impeller.
