The honeycomb rotary dehumidifier dryer uses ceramic fibers as the substrate to form honeycomb rotary wheels, and a special chemical synthesis two-stage crystallization method is used to uniformly crystallize the moisture absorbing agent silica gel and molecular sieve on the ceramic fiber rotary wheel substrate, making it highly hygroscopic. There are countless mesh like pores on its entire surface, where water molecules in the air are adsorbed and dehumidified, and heated to detach from the pores and regenerate. Its wheel not only has excellent moisture absorption effect, but also has the characteristics of fire resistance, acid and alkali resistance, and washability.
