Abstract

The invention provides a compound dryer. The compound dryer comprises a rotating cylinder, a drying material, a hot air provider, a hot air chamber and a scraping unit. A drying material provider is arranged above the rotating cylinder; and the drying material is coated on the surface of the rotating cylinder. The hot air provider is connected to two sides of the rotating cylinder, and comprises first and second hot air pipes. The first and second hot air pipes alternately provide hot air into the rotating cylinder or alternately exhaust the hot air through the rotating cylinder. The hot air chamber is arranged at the external of the rotating cylinder along the outer surface of the rotating cylinder. The scraping unit is arranged on one side of the rotating cylinder; and the drying material is removed from the surface of the rotating cylinder after being dried by the rotating cylinder and the hot air chamber.

Description

technical field [0001] The present disclosure relates to a hybrid dryer in which indirect and direct heating are combined. More specifically, the disclosure of the present invention relates to a compound dryer for mud-like materials in which the mud-like materials with relatively high viscosity and cohesiveness are accurately and precisely provided and dried. Background technique [0002] Sludge-like materials such as medical or chemical ingredients, microalgae, airgel pastes, sewage sludge, organic materials, animal waste, marine sediments, etc. having micro-particles with a unit size of micron are dried to remove water therein, and then widely used. Therefore, various dryers for drying mud-like materials have been developed. [0003] For example, Japanese Application Laid-Open No. 2001-47841 discloses a drying device in which a viscous material to be dried is supplied between stirring blades due to the rotation of the stirring blades. However, in a drying device in whi...
