Drying a Bean-Curd Refuse in a Mixed-Flow Dryer

Drying characteristics of bean-curd refuse were measured in a mixed-flow dryer, which was a conductive indirect-heating dryer using steam as a heating medium and had an agitated solid bed. Effects of agitating speed and solid inventory were discussed on drying characteristics of bean-curd refuse. Height of a solid bed increased with increasing agitation speed. The evaporation rate and the overall heat transfer coefficient increased on the heating surface as bed mass of the drier or agitation speed increased. Water content of dried solid decreased with increasing bed mass of the drier or agitation speed.
