Study on the aerodynamic drying technology with particle classification for paste materials

Abstract

Nowadays, we often meet the problem of paste materials drying in the industries of chemistry, pharmacy, agricultural product processing, Differentiating normal particles, paste materials are often agglutinate and difficult to be dried. Besides, agglutinated material mass after drying, in many cases, need further crushing and classification, which makes the process high cost. The integration of aerodynamic principles with the crushing and classification in one single equipment could partly satisfy the requirements. Experiments with paste calcium carbonate and cassava starch have proved the reasonability of the design and applicability of the prototype equipment. It is hoped that the calculation method could be applied to the design of equipment in bigger scale.
