This invention discloses a drying method for paste and its dynamic vacuum drier which includes a tank, shell, top cover, bottom cover in which, an interlayer is formed between the tank and the shell, the tank is linked to a suction pipe connecting with a vacuum pump and a screened plate is in the tank separating it to up space and low space interlinked with the suction pipe. A paste, put on the screen plate, is divided into several 1-3 mm strips by the screen holes under the pressure difference to be dried dynamically and continuously in the high vacuum low space to increase surface dry area of paste by times or magnitude orders to reduce drying time. |
