(1) If the initial moisture content of the dried wood before drying is very different, such as when the difference is more than 20%-30%.

(2) When the moisture content of the wood has reached the required final moisture content value through the detection of the inspection board, there may be a part of the wood whose moisture content has not fully met the requirements, and the actual moisture content of different dried wood at that time is very different. .

(3) When the moisture content of the dried wood has reached the required final moisture content value through the inspection of the inspection board, there may be a part of the wood whose distribution of moisture content along the thickness direction is not uniform, and the moisture content of the inner layer is still high. .

(4) When the requirement for uniformity of the final moisture content of the dried wood is relatively high, you should carry out balanced treatment, that is, making the wood that has reached the final moisture content no longer be dried, and continue drying the wood that does not meet the final moisture content requirement. This treatment could improve the drying uniformity of the final moisture content of the entire pile of woods and could keep the distribution uniformity of moisture content along the thickness direction of the wood.
