Three-cylinder dryer manufacturers describe the technical principle of the dryer
The physical method of the dryer is what we often call "drying", and the characteristics of drying are actually the use of heating, cooling and decompression, and the moisture in the material can be volatilized and condensed. All for the purpose of dehumidification.
Some dryer technology dehumidification means, for example, the liquid is heated and concentrated, although it also has the characteristics of thermophysical dehumidification, but people are accustomed to not think that concentration is a drying technology. With the development of the times, people have gradually incorporated some new dehumidification technologies that do not belong to thermophysical methods into the category of drying technologies, such as molecular sieves and supercritical flow extraction. Therefore, the definition and category of drying technology is a conventional and constantly expanding concept.

The drying technologies commonly used in traditional industrial production dryer technology mainly include: chamber drying, tunnel drying, drum drying, drum drying, belt drying, disc drying, paddle drying, fluidized bed drying, spray drying, etc. Moving bed drying, spray drying, airflow drying, vacuum freeze drying, solar drying, microwave and high frequency drying, infrared heat radiation drying, etc. These traditional drying technologies have a long development history, are mature and reliable, and have been widely used in the world and my country.
In recent years, a number of new dryer technologies have emerged, including pulse combustion drying, colliding flow drying, impact penetration drying, sonic field drying, supercritical fluid drying, superheated steam drying, contact adsorption drying, etc. Compared with the traditional drying technology, the new technology has a certain breakthrough in mechanism, but it still needs to be improved in terms of industrial application. At present, these new drying technologies in my country are still in the early stage of research.
