Crowd out unit using screw that the big proportion of length and diameter , the effictiveness of plasticizing is very good . the head of mould using advanced electromotive system and hydraulic system , the degree of automatization is high , acting facillitately and the high of product efficiency . the head of mould using heating method inside , adjusting easily , the thickness of sheet is very precise , and the availability of heating is high , and saving the electricity 挤出机采用大长径比螺杆，塑化效果好模头换网部分采用先进电动液压装置，自动化程度高，操作方便生产效率高模头采用内加热式，具有调模容易板片厚薄更精确均匀，更为突出的是热利用率高省电节能温度控制采用
At the basis of matching test , the paper has an idea to enhance the heat unitization rate of dy generator , which is unitizing the heat deposited in the generator to supply heat needed by the generator ’ s de - adsorption . the test verifies this method is contently feasible to enhance the cop of dy generator 在匹配实验的基础上，提出了一种提高dy发生器热利用率的方法，即利用发生器内储蓄的显热为发生器提供脱附所需的热量，实验证实该种方法在对于提高发生器的cop是切实可行的。
Comparing with internal heating type fluidized bed , vibration fluidized bed , which get the material to fluidized state through mechanical vibration , can improve thermal utilization factor , quality and reduce steam and power consumption , and one time investment while keeping all advantages of internal heating type fluidized bed 振动式流化床是一种利用机械的振动，使物料达到流化状态，它在保留内热式流化床干燥器优点的基础上，在热利用率，产品质量，降低蒸汽及电力消耗，设备一次性投资低等方面均较内热式流化床有较大提高。
