Wet storage
A wet storage referred to in the timber industry a repository of is proposed timber in which the logs for the purpose of preservation are irrigated artificially.
description
The wood is stored in the wet store until it is sent for further processing in the sawmill . Storage is possible for several years without any loss of quality, with the optimal storage period depending on the type of wood. For softwood , the period of two to three years is considered optimal. In exceptional cases, however, four to five years are also possible. With hardwood ( beech ), the wood should only be stored for a few months to a maximum of a year. A reduction in quality is to be expected from the third year of storage.
The irrigation fills the pore system of the wood, which prevents the outside air from penetrating. Pests such as B. the bark beetle , other insects and fungi are thus deprived of their livelihood and the infestation is prevented. The wet storage also prevents drying out and thus the formation of dryness or shrinkage cracks .
It takes about three months for the wood to become soaked with water. Nocturnal irrigation can then be dispensed with. The operating costs for the storage space amount to three to five euros per cubic meter and year. Wet storage facilities are usually sprinkled with water from nearby rivers or ponds. The irrigation water is collected again by a system of ditches and fed back into a collecting pond, from where it is reintroduced into the irrigation cycle.
The wet storage process is particularly useful when larger quantities of felled wood are to be preserved over a longer period of time, for example after major storms. In this way, a financial loss can be avoided if the market price falls due to the large supply of wood.
In some regions of Germany, many wet wood storage facilities were created as a result of the storm damage caused by Kyrill in 2007. When such storage facilities are set up near rivers, care is taken to ensure that there are openings for amphibians to the waters.
Winter operation
With constant temperatures below 0 ° C, regular irrigation is not necessary in winter. Ideally, an ice sheet forms on the wood.
