The invention provides a control system of a material drier device. The control system is used for sampling a moisture measured value, a temperature measured value on the side surface of the dryer and an outlet air temperature measured value and an outlet air speed measured value of a hot air blower by utilizing a sampling unit; an outlet moisture control unit is used for modifying an outlet air temperature set value of the hot air blower, an outlet air speed set value of the hot air blower and a dryer surface temperature set value according to the changes of the sampled moisture measured value of the material outlet and the moisture measured value of the material inlet; a steam valve control unit is used for controlling the opening-closing size of the steam valve according to the difference of the dryer surface temperature set value and the sampled temperature measured value; and a hot air blower control unit is used for controlling the hot air blower to change the outlet air temperature according to the difference of the outlet air temperature set value and the sampled outlet air temperature measured value, and controlling the hot air blower to change the outlet air speed according to the difference of the outlet air speed set value and the sampled outlet air speed measured value.
Description
technical field [0001] The invention relates to a control system for material dryer equipment. Background technique [0002] Material drying cylinder equipment is mainly used for drying tobacco, dry goods and other materials. Its equipment is like a horizontal cylinder with a hollow cavity inside. Hot steam flows in from one end of the cavity to heat the equipment and form steam condensate, which then flows out from the other end. There are also designs in which steam flows into one end at the same time, circulates in the chamber and then flows out from the same end. As the equipment rotates, the moisture of the wet paper attached to the surface of the equipment heated by the hot steam is evaporated, and then enters the next process. Therefore, this rotary drying and heating equipment is usually also called a drying cylinder. [0003] In order to control the moisture after drying within the range required by the process, it is necessary to apply an automatic moisture cont...
