A MESURING AND CONTROL APPARATUS OF AIR VOLUME FOR VENTILATION DRY

摘要

The present invention provides a wind volume measuring and controlling apparatus for ventilation drying, wherein the apparatus quickly and efficiently performs a drying process through accurately controlling wind volume and wind velocity. The provided apparatus comprises a dryer (30) and an air feeding unit (20) being placed at one side of the dryer (30) and feeding hot air into the dryer (30), wherein the dryer (30) includes: an air feeding part (31) into which air is fed from outside; an air discharging part (32) from which the fed air is discharged; a pressure sensor (33) measuring the pressure of the air fed into the air feeding part (31); a temperature sensor (34) measuring the temperature of the air fed into the air feeding part (31); and a control part (35) receiving the value of the pressure measured by the pressure sensor (33) and the value of the temperature measured by the temperature sensor (34), computing the wind velocity and wind volume of the air fed into the air feeding part (31), and feedback-controlling the wind velocity and wind volume of the air fed into the air feeding part (31) by comparing the value of the computed wind velocity and wind volume with predetermined reference values.
