TIMBER Recusorb dehumidification/wood drying keeps sawn timber permanently in shape

Every hygroscopic material that is exposed to the ambient air will sooner or later establish an equilibrium with the surrounding air. This means that the material in question also adapts in terms of temperature and product humidity. The prevailing humidity in particular can result in sensitive quality changes for wood that is temporarily stored after cutting and pre-drying. However, as customers' quality requirements are increasing all the time, this requires controlled storage in order to ensure the required quality and prevent wood moisture.

Fluctuating climatic conditions during timber drying

Pre-dried sawn timber, for example, which is to be used for furniture production, must not contain more than 8 - 9% water. Or even joinery wood that is processed into doors or windows should have a product moisture content of approx. 12%. However, if this wood is stored under uncontrolled humidity, considerable fluctuations in quality can occur. Fluctuating and uneven moisture absorption can cause the wood to warp. This in turn can impair further processing in the furniture factory and call into question the quality of the end product. This can even lead to rejects, so that there is a risk that the customer will no longer accept the goods and the sawmill will be left with its goods.

Controlled humidity, consistently high quality.

The humidity required to maintain the drying condition of the wood is practically independent of the temperature in the warehouse. Heating is therefore not advisable when drying wood. K.I.R.S.C.H. uses dehumidifiers for this application to ensure consistent dehumidification throughout the year, even at low temperatures. These work according to the TIMBER Recusorb principle, an energy-optimized sorptive dehumidification system. At the heart of this technology is the world's highest quality SSCR-U rotor developed from silica gel and several metal-silicate compounds. Compared to the classic sorption principle, the TIMBER Recusorb also works with internal heat recovery. The incoming regeneration air (dark green) absorbs the residual regeneration energy of the rotor in the flushing zone, is preheated and its water content is reduced. As a result, the regeneration heater consumes less energy and the rotor is regenerated better in accordance with the lower regeneration air humidity.

TIMBER / RECUSORB dehumidification principle

The operating costs for dehumidification are very low. Alternatively, electrical energy, steam or natural gas can be used as regeneration energy, depending on availability at the site.

Interpretation

The TIMBER Recusorb is designed according to the desired air humidity (e.g. 40% RH) for storage as well as the size, construction and location of the warehouse. The required dehumidification performance can be minimized by minimizing the opening times of the warehouse door (e.g. fast-opening door) and by arranging the air exchange in the warehouse accordingly.

Operating costs are falling!

The required relative humidity is kept at a constant 40% using TIMBER Recusorb dehumidification, regardless of the temperature and season.

Energy optimization / control

The dehumidification performance of the TIMBER Recusorb is continuously controlled by measuring the relative humidity in the storage hall. The desired humidity for storing sawn timber with a residual moisture content of 8 %, for example, is approx. 40 % RH. On days when the relative humidity of the outside air is already below 40 %, no dehumidification takes place and no energy is consumed. Thanks to the TIMBER Recusorb dehumidification system installed in the warehouse, both domestic and foreign customers can now be supplied with furniture and joinery wood with a very low water content.

Advantages of dehumidification for military equipment

Equalization of the remaining wood moisture immediately after pre-drying in the drying kiln is optimal, as the air humidity in the warehouse is in equilibrium with the desired drying state of the wood.

Ensuring the correct water content of the wood, regardless of the storage time. After equalization, the drying condition of the wood remains constantly unchanged due to the “dry” storage at the correct humidity.

No unnecessary energy consumption due to drying to a lower residual moisture content to compensate for the new moisture absorption of the wood during storage

Quality assurance in the production of furniture and joinery wood

No post-drying is required before further processing

Uniform degree of drying of the wood even with large delivery quantities

No deformation due to uneven moisture absorption in the wood during storage

Constant humidity regardless of temperature and season
