Profiled beams drying kiln from the manufacturer

Profiled beams is a reliable material for the construction of a wooden house. With proper care, the house of profiled beams will serve you more than 100 years. The main thing is to choose a good beam from a reliable manufacturer. The quality of the beam determines some criterias. They are geometric parameters, wood color, number of cracks and humidity. Since the humidity inside the wood can significantly affect its structure and the quality of the timber. Let us consider this indicator in more detail.

Profiled beams` kinds

The moisture content of the timber is the basis for classification:

• beam of natural moisture

• naturally-dried beam

• chamber drying beam

The profiled bar of natural moisture does not go through the drying stage in production and contains a large amount of water. After construction, the wet beam gives a strong shrinkage. This significantly affects the design of the house.

The production of a profiled beam, which was dried naturally, relieves it of excessive moisture. But this method of drying takes a lot of time. The beam is stacked and dried in the wind. It is important to understand that moisture is in the tree in two forms. There are free (intercellular) and bound (intracellular) moisture in wood. It is not possible to remove the bound moisture by this method of drying.

The chamber drying beam from the manufacturer has undeniable advantages over the first two species. During the drying process, both types of moisture are extracted.

What is chamber drying for?

First, let's see what the technology is. Chamber drying is the physical process of extracting moisture from wood, which allows you to reduce the drying time of the material at times.

Why is it necessary to choose profiled beam of chamber drying from the manufacturer?

Wood can dry and in itself after the construction of the house. But excess moisture can seriously affect its quality. The fact is that the outer part of the timber dries faster than the inner one, and therefore deforms (decreases) also faster. This leads to the appearance of significant cracks on the beam.

2) If the wood, dried in the chamber, will subsequently get wet, it will absorb only the intercellular moisture. And as the rain ends it will immediately start to give this moisture back. There will be no excess moisture inside the cells.

The technology of chamber drying

There are several types of chamber drying. They are convection, vacuum, vacuum-pulse, microwave drying, condensation and others. The company & laquo; Yumax & raquo; uses convection chambers when preparing profiled beams for construction. This is the most popular method of drying. It is the most profitable from the economic point of view and allows in sufficient quality to dry coniferous wood.

The work of the convection chamber is based on the difference of partial pressures. The pressure of the vapor in the cold is much less than the vapor pressure in the heat, so the heated steam always aspires to go out the chamber. The heat carrier in the convection chamber is water heated in the boiler. The heating itself occurs with the help of radiators. Moisture from the surface of the wood is removed by the fans. It accumulates in the chamber, and then it is released into the atmosphere. The temperature in the chamber at this moment can reach 60 ° C. Profiled beam is laid in the chamber exactly, so that all gaps are of sufficient cross-section and allow the movement of air.

Parameters of wood`s quality, which past chamber drying

In laboratory conditions, the quality of drying is determined by weighing the beam before and after the procedure. The check can be arranged in a domestic environment with the aid of a moisture meter. And both outside and inside the beam (in the place where the bowl is cut out). If the indicator is 18-22%, this value is sufficient to ensure that the tree remains high-quality and well absorbed protective impregnation and varnish-colorful materials. It is the value guaranteed by the company "Yumax".
