摘要
采用流化干燥技术,使竹粉在干燥室内呈现“沸腾”状态,从而使竹粉颗粒与热空气接触面积最大化,实现迅速去除其内部水分的目的。通过计算机自动控制干燥过程中,气流速度、干燥室温度等技术参数,使干燥过程更加合理。设计热泵除湿装置,除去水分,回收剩余热量,并将热量返回干燥室,达到节能的目的。
Fluidized drying technology is adopted to contribute to a“boiling state”of bamboo powder in the drying chamber,thereby maximizing the area of contact between bamboo powder particles and hot air,and achieving the purpose of quickly removing the internal moisture,with computer used to automatically control such technical parameters as air flow speed,drying chamber temperature in the drying process to make the drying process more rational,with a heat pump-based dehumidifying device designed to remove moisture and recover the remaining heat to be returned to the drying chamber,thus achieving the purpose of energy conservation.
