Dryer classification: 1. According to the operating pressure of the dryer, it can be divided into two types: normal pressure type and vacuum dryer. According to the operation mode of the dryer, it can be divided into two types: indirect operation and continuous operation. According to the state of the material to be dried, it can be divided into a block material, a strip material, a granular material, a paste material, a solution or a slurry material dryer, etc. According to the type of drying medium suitable for the dryer, it can be divided into air, flue gas, superheated steam, and inert gas as drying medium. According to the structure of the dryer, it can be divided into spray dryer, fluidized bed dryer, airflow dryer, rotary drum dryer, drum dryer, various box dryers, etc. According to the method of supplying heat to the material according to the dryer, it can be divided into conduction heating dryer, convection heating dryer, radiant heating dryer, high frequency heating dryer, etc. A newer classification method, the dryer is divided into two categories, five categories and two categories are adiabatic drying process and non-adiabatic drying process. The adiabatic drying process can also be divided into two categories: one is a small particle material dryer, such as a spray dryer, a gas flow dryer, a fluidized bed dryer, and a rotary drum dryer. The second is a block material dryer, such as box drying. Middle tunnel dryer, multi-belt dryer and belt dryer. Non-adiabatic drying process can be divided into three sub-categories: vacuum dryer, conduction heat transfer dryer, radiation heat transfer dryer, which is characterized by non-adiabatic system.
