HYBRID DRYER FOR HIGH VISCOUS MATERIALS

摘要

The hybrid dryer of the present invention comprises: a rotatory cylinder; a materials-to-be-dried supply unit; a hot air supply unit; a hot air chamber; and a scraping unit. The materials-to-be-dried supply unit is placed on the top of the rotatory cylinder to spread the materials-to-be-dried on the surface of the rotatory cylinder. The hot air supply unit comprises a first hot air pipe and a second hot air pipe, which are respectively connected to both sides of the rotatory cylinder to provide hot air into the rotatory cylinder in turn or to discharge the hot air, which has passed through the rotatory cylinder, in turn. The hot air chamber is placed outside the rotatory cylinder along an outer circumferential surface of the rotatory cylinder, and the hot air, which is resupplied through the rotatory cylinder, passes through the hot air chamber. The scraping unit is placed on one side of the rotatory cylinder to remove the materials-to-be-dried, which are dried by the rotatory cylinder and the hot air chamber from the surface of the rotatory cylinder. The present invention aims to provide a hybrid dryer for highly viscous materials, which has an improved drying efficiency and settles the system disorder that occurs when drying highly viscous materials.
