    • Methods and systems are disclosed for drying a material or, more generally, flash evaporating a target substance having a vapor pressure threshold. The methods and systems include a conveyor conduit that receives material. The material moves through the conveyor and is expelled into a pressure drop zone created by one or more venturi nozzles. As the material encounters the pressure drop zone, the targeted substance in the material experiences a rapid and extreme pressure drop and simultaneously a rapid temperature increase. This causes the target substance in the material to flash evaporate virtually immediately. The resulting vapor is separated from the remaining material and the now dry material is collected for further processing or use. The vapor can be collected, condensed, exhausted, or otherwise treated depending upon the goals of a particular installation or process.
    • 公开了用于干燥材料的方法和系统,或者更一般地,闪蒸蒸发具有蒸气压阈值的目标物质。 方法和系统包括接收材料的输送管道。 材料移动通过输送机并被排出到由一个或多个文氏管喷嘴产生的压降区域中。 当材料遇到压降区域时,材料中的目标物质经历快速和极端的压降并同时迅速升高温度。 这使得材料中的目标物质几乎立即闪蒸。 所得的蒸气与剩余的材料分离,并且收集现在的干燥材料用于进一步的加工或使用。 可以根据特定安装或过程的目标收集,浓缩,排出或以其他方式处理蒸汽。
