Technical Field

The utility model relates to the technical field of drying machines, in particular to an energy-saving hot air drying machine.

Background

The dryer is a mechanical device for reducing moisture of materials by using heat energy, and is used for drying objects. The dryer vaporizes moisture (typically moisture or other volatile liquid components) in the material by heating to escape to obtain a solid material of a specified moisture content. The purpose of drying is for material use or further processing requirements. The dryers are classified into an atmospheric dryer and a vacuum dryer according to the operation pressure, and the dryers are classified into an atmospheric dryer and a vacuum dryer (the vacuum dryer is also called a vacuum dryer) according to the operation pressure. The dryer of the recent generation started to use a fixed bed dryer which is operated intermittently. The types of mechanical equipment used for carrying out the drying operation are numerous and can be divided into atmospheric pressure and reduced pressure (reduced pressure dryers are also called vacuum dryers) depending on the operating pressure. The method can be divided into a batch method and a continuous method according to the operation method. Air, flue gas or other drying media may be classified according to the drying media. Depending on the mode of movement (material movement and drying medium flow) there can be a division into cocurrent, countercurrent and crossflow. According to the operation pressure, the drying machine is divided into an atmospheric drying machine and a vacuum drying machine, the partial pressure of moisture steam in a space can be reduced by operating under vacuum, the drying process is accelerated, the moisture boiling point and the material drying temperature can be reduced, and the steam is not easy to leak, so that the vacuum drying machine is suitable for drying heat-sensitive, easily oxidized, explosive and toxic materials and occasions where the moisture steam needs to be recovered.
