Company Ecosis Ltd has its own drying chamber with a capacity of up to 50 m3 of material. The service is offered as per material, produced by us, as well as for the customer's material.
Why is the drying process important??
Drying is a process, in which the available moisture in the wood is reduced to a certain degree naturally or artificially. Depending on this, atmospheric drying differs from atmospheric air, chamber drying – regulated reduction of humidity in wood by means of drying agents in special closed rooms (drying chambers), and chemical drying- by treating the wood with water-soluble substances or salts, which, in high concentration, push the water to the periphery of the tree. Chemical drying is not used as a self-drying method, and as a means of preparing the wood for drying.
There are a few things to know about drying. Under normal conditions, the wood has an equilibrium moisture content. Balanced, because it depends on the humidity of the surrounding air. There is always a tendency to equalize the partial pressure of air and wood. When the partial pressure of the air is less than that of the wood the moisture gradient is from the wood to the air – we say that the wood dries. When the partial pressure of the air is greater than that of the wood the moisture gradient is from the air to the wood – then we have wetting of the wood. Equilibrium moisture usually ranges from 7% to 9-10%, depending on the air humidity, its temperature and sea level.
Atmospheric drying of wood means the release of moisture under the influence of the climatic requirements of the respective place. To avoid significant quality degradation, great care must be taken with the material being dried, protecting especially from direct sunlight and longer exposure to water. Certain measures, such as stacking with thick dividers, small figure width, embedding vertical openings, increasing circulation in the figure with material, leaving a thick air gap under the figure, etc., are only aimed at shortening the drying time. Depending on the climate, the wood can reach a minimum moisture content, which corresponds to the equilibrium moisture content at the actual temperatures and degree of water vapor saturation in the air. Regardless of all this for most areas of application (where the required moisture content lies below the air-dry value) additional technical drying of the wood is required. From an economic point of view, atmospheric drying of wood involves large working capital over a long period of time.
Unlike atmospheric drying at technical drying, which is offered by Ekosis EOOD in its own modern drying chamber, the drying agent has a much higher temperature and often a significantly higher speed of movement. This is achieved through special heating and ventilation systems (technical resources). Technical drying is mandatory in cases, when the final moisture content of the materials u < 15% and when moisture must be removed from the wood for a short time. In technical drying, this result is achieved by appropriate temperature regulation, the humidity and the speed of movement of the drying agent. Drying facilities require significantly more investment, than in setting up warehouses for atmospheric drying. Therefore, the aim should be to make drying using the latest advances in science in the shortest time and achieving the highest quality of dried wood.. A prerequisite for achieving high productivity is the maximum filling of the volume of the dryer and the correct arrangement, or. placement of the material relative to the drying agent. A drying cycle should only be carried out with materials, which have the same thickness and approximately the same initial humidity.
Company Ecosys Ltd is specialized in technical drying processes in a drying chamber of the latest generation, which facilitates the processes of drying the material and achieving the desired degree of humidity of the wood material.
