Use wood dehumidifier to avoid common defects and solutions in wood drying

            Use wood dehumidifier to avoid common defects and solutions in wood drying 

1).common defects and solutions in wood drying 

1, cracking: wood in the kiln drying process cracking phenomenon has the following three situations:

2, external crack (surface crack) : refers to the outer surface of the sawn timber (usually the outer section of the chord cutting board) along the longitudinal crack of wood ray, it is mainly caused by excessive surface stress in the early drying, so the early drying should try to avoid heating up too fast, control the temperature gradient.

3. End crack (split or longitudinal crack) : when wood is dried in the kiln, it is easy to produce end crack due to the rapid evaporation of water at the end of wood, especially when the wood thickness is large.

4, internal crack (honeycomb crack) : wood internal crack occurs in the wood, along the wood ray crack, such as honeycomb, also called honeycomb crack. Internal crack generally occurs in the late drying, the way to prevent is in the kiln dry, late timely intermediate treatment, in order to remove the surface hardening, for a large thickness of converted wood, especially hard broad-leaved wood, late drying temperature must not be too high.

2) Eseego wood dehumidifer use the heat pump technology for wood drying, the digital control system can precise temperature control. It can protect well the wood material when drying
