Kiln drying out is the procedure of heating logs of wood in the purpose-built kilns for a factor where their excess dampness levels are evaporated, thus quickening the seasoning process as well as achieving a better final result. Optimal dampness levels for residence fire gas are from 20% and below, as well as the kiln drying out process at the same time burns off any pollutants using up by the timber in nature.
The kiln drying procedure
From the minute trees are collected, they are first given to a woodwork mill and there they get debarked, as well as categorized, in their relative sizes, kinds, and shapes. This is an essential step in the wood log drying kiln procedure as logs, and are organized with each other in the same dimensions are going to be dried for equivalent dampness levels.
As soon as organized, the timber is then traveled in batches via the kilns comprised of four areas, particularly: the chamber, the airflow system, the warmth exchanger, as well as the air fans.
- Chamber: Generally, built-in concrete or block, the chamber provides the housing for wood sets that are to be heated up. Modern kilns, however, are often tending in the direction of newer materials, such as glass, aluminum, as well as polyurethane foam.
- Heat exchanger: Heat gets entered in the chamber either by steam heat exchangers or via conventional furnaces which pass gases through huge flue.
- Airflow system: The objective of the ventilation system is to manage dampness levels inside the chamber and essence any kind of water that has vaporized from the logs at the time of the heating procedure.
- Air fans: These fans are in charge of both the transfer of warmth as well as vaporized water in the chamber. Air fans are usually dealt with to the inside of the chamber itself.
Once the timber has attained the ideal moisture levels of below 20%, it will be moved to a planer to be cut right into certain dimensions according to the devices in which it will be utilized.
