What is the preheat treatment of Medicine Residue Dryer

Preheating treatment of wood drying equipment is a major event.Medicine Residue Dryer How to do preheating treatment is a very important part. The following is a simple share with you: First,Medicine Residue Dryer the time required for preheating treatment of wood drying equipment depends on the wood species,Medicine Residue Dryer The thickness and the moisture content of the furnace are determined by using the material with a thickness of 50mm as an example. Under normal conditions,Medicine Residue Dryer the initial spray is 12-15h. In order to obtain a reasonable temperature gradient,Medicine Residue Dryer the cooked data also needs to stop the treatment of 6 ~ 8h. Regarding Quercus glauca and Southern oak,Medicine Residue Dryer these two types of materials are very rich in parenchyma cells, ray parenchyma cells, mahogany wood, patty, gamba,Medicine Residue Dryer and other highly dense materials. It is usually sprayed for 24 hours to completely soften the wood and dredge the cell cavity.Medicine Residue Dryer Dissolve the filling material in the cell cavity locally to prepare for the subsequent drying process.

The temperature of the initial spraying should not be too low,Medicine Residue Dryer otherwise the steam flow into the furnace is too small, lacking to make the relative humidity in the furnace reach the reference request,Medicine Residue Dryer the effect of preheating treatment is not good,Medicine Residue Dryer the ordinary initial treatment temperature is 95-100 degrees. The above is related to wood drying equipment,Medicine Residue Dryer I hope to help you.
