Vertical Ribbon Vacuum Dryer is a multi-function mixer combines mixing, reaction and drying. It is widely used in industries of food, adhesive, lithium battery, etc. The mixer is equipped with heating jacket, and its main shaft and ribbons can be also with heating function (to improve drying efficiency furthermore). Its main shaft is with mechanical seal to achieve high vacuum sealing effect. Connecting to the vacuum system, it can realize efficient drying (the drying efficiency is 3-5 times than that of the double cone rotary vacuum dryer with same specification); In front of the vacuum system, it is equipped with a dust collector, a condensation recycle device, a solid-gas separation device, etc., in order to reduce the loss of raw materials a ...
