Abstract
A flowable material, such as a supercooled melt or supersaturated solution, is dispensed onto a take-up member such as a belt or drum. Either prior to, or after being dispensed onto the take-up member, the material is exposed to ultrasound to promote the crystallization of solid substances in the material. All of the material or only a portion of the material can be exposed to ultrasound. If only a portion is exposed, it is later combined with the rest of the material prior to being dispensed onto the take-up member.
