詳情
  Fresh wood contains a lot of ♠βwater, and in certain enviroΩ&®₩nments, water will continue to evaporate.σλ The natural evaporation of water will caus£§±e defects such as shrinkage, cracking, bending←✔∞∏ deformation, mildew,©>→¥ etc., which will seriously affect the qualit£'&y of wood products. Therefore, thλπσ≤e wood must be forced (controlled) to dry duΩλ∏γring the production of various₹¥ wood products. Proper drying can overco σme the above-mentioned w™  ood defects, improve the mechanical streng≠>✘∑th of the wood, and improve the pδ©≠¥rocessing performance of the wood. It •λis the rational use π÷♥γof wood, an important technical measure of the &¶value of wood, and it is also an ✔ indispensable main p≥∏'∑rocess for the production of ♥ ™<wood products.
  Wood drying equipm♦"&<ent = oven
  Wood drying equipmen$λ &t realizes forced dry>βing of wood, and it must÷✘ have three basic funπ<♦→ctions: heating, humidity and venβ∏tilation. The heating function™✔€& is self-evident; humi§ εdity (spray steam or atomized wδ€"ater) is used to protect certain stε ages of drying require∞β& d for high-humidity envir&₩onments to prevent cracking, deformat♣β×‌ion, etc.; ventilation equipment must ensure t☆>hat humid and hot air passes through al§ ®↔l parts of the material eve↕♠nly. The wood has a un×≠≈iform moisture content. A simple w₽✔™ood "oven" is generally a hot or direct heat₽γing stove, it is difficult to organize ₽γ‌<a reasonable air circulat§γ←ion, and the humidity is diffic$←€♠ult or impossible to ad'$ just. It is very difficult to obt ♣★ain a good drying effect with thisλ  simple equipment.
