Causes and control of uneven drying of wood

1. The general reasons for the occurrence:

(1) The aerodynamic state of the drying chamber is poor;

(2) Uneven heat dissipation of the heater;

(3) The pile stacking code is unreasonable, and the airflow in the kiln is uneven;

(4) The difference in moisture content of wood before entering the kiln is too large;

2. Prevention and correction methods:

(1) Check the heating pipe, remove the condensed water and air from the heating pipe, check if the drain pipe is out of order, and whether the return pipe is gambling. The heating tube can work normally and the heat transfer is uniform;

(2) Ensure that each fan is in normal operation, and there must be no opening or closing;

(3) reduce the difference in moisture content of wood before entering the kiln;

(4) Timing of the fan;

(5) Pay attention to the uniform distribution of air along the height direction of the pile;

(6) Reasonable accumulation, so that the airflow in the kiln is evenly circulated.
