| Abstract: | his paper presents the structure, operation principle and the application field of the Spin Flash Dryer, which is developed by the authors and particularly suitble for the hard-to-dry paste-like stickum. Investigations show that there are both potential flow zone and plane circular flow zone in the tangential velocity distribution (TVD) of an ideal cyclone. The plane circular folw is the major flow trend in the TVD of the said dryer but no potential flow zone. It's beneficial to drying the paste-like stickum for the velocity distribution pattern. |
