| Research Abstract |
Swelling is a phenomenon which fine packed beds such as polymer and clay absorb liquid by osmotic pressure and increase the volume. Drying and dehydration in swelling materials are very important problems in wide fields such as agriculture, food science and bioengineering.
In drying of swelling materials, dehydration process is needed before drying process. We presented here two methods for dehydration processing of swelling materials. One is the method by electro-osmotic flow caused by applied electric field. The other is the method of freezing separating moisture from swelling materials. It was found that both methods were investigated experimentally and were effective for dehydration of swelling particles.
