Abrégé

The invention relates to a drive-through wood drying kiln as well as a conveyor. Accordingly, a drive-through drying arrangement comprises a drying tunnel (4), a conveyor (5a), with which a train consisting of a number "n" of successively track-guided conveying units (3a) loaded with wood (2a), through "drawing" can be transferred from an input port (8) to an output port (9). To obtain improved flexibility and capacity, it comprises, within the drying tunnel (4), a plurality of conveyors (5a, 5b, 5c), laterally arranged alongside each other, each of which, through carrying out "drawing", can transfer a train belonging to each conveyor by means of a number "n" of successive conveying units (3a, 3b, 3c) loaded wood (2a, 2b, 2c) with wood loads (2a) from an input port (8) to an output port (9), whereby the conveyors (5a, 5b, 5c) are equipped with such mutually arranged drive units (13) that at least two of these (5a, 5c respective 5b) can carry out "drawing" for different periods of time or time intervals.

Abrégé

This invention concerns a method for the drying of material (1) by air that is caused to circulate around and/or through the material (1), where the drying comprises at least two subprocesses (A, B) and where the circulation air in each subprocess (A, B) is conditioned to considerably different wet temperatures (TvA, TvB). The energy recovery takes place through the circulation air in one of the subprocesses (A, B), the subprocess with higher wet temperature (TvA, TvB), being divided into at least two subsets (3, 4), where one subset (3) is demoisturised through condensation, where energy obtained during the condensation process is transferred to the second subprocess (A, B), to the circulation air with the lower wet temperature (TvA, TvB), and where the other subset (4) of the circulation air is led past the condensation process. The invention concerns also an energy-recovery system (2) and a drying arrangement (10).

Abrégé

The invention concerns a method of drying of material, in particular timber, using warm air, where the drying process is divided into at least a first and a second subprocess (A, B), in series with each other, and the circulating flows (2) of the two subprocesses in the relevant drying chambers are conditioned to significantly different wet temperatures (TvA) and (TvB), respectively. In order to achieve a reduced energy input, the circulating air (2) in the first subprocess (A) is given a higher wet temperature (TvA) than the circulating air (2) in the second subprocess (B), and that heat in the circulating air (2) in the first subprocess (A) is recovered and transferred to the second subprocess (B).

Abrégé

This invention concerns a method for the displacement of a vertically displaceable motor driven door leaf 1 in an opening 2 in a building 3. The method comprises that a first line drum 4 comprising a first axis of rotation 5 that is caused to interact with a first line 6 that has been attached to the line drum 4 and the door leaf 1, a second line drum 7 comprising a second axis of rotation 8 that is caused to interact with a second line 9 that has been attached to the line drum 7 and the door leaf 1 [sic, syntax]. A force of rotation is transferred from a motor unit 10 to the axis of rotation 5 and 8 of the relevant line drum through a power-transfer unit 11 whereby the line drums 4 and 7 are rotated and the first line 6 is rolled onto or rolled off from the first line drum 5 [sic, "4"?] and the second line 9 is rolled onto or rolled off from the second line drum 7, whereby the door leaf 1 is displaced upwards or downwards. The power transfer unit 11 is caused to act on at least one axis of rotation 5 or 8 since two cogs are always in interaction with each other in a gear system 12 comprised within the power-transfer unit 11, and it acts on at least one axis of rotation 5 or 8. At least this axis of rotation 5 or 8 is rotated in this case, and a transmission unit 13 is caused to interact with the first axis of rotation 5 and the second axis of rotation 8, and ensures that the rotation of the axis of rotation 5 or 8 that is caused to rotate with the aid of the power-transfer unit 11 is transferred to the second axis of rotation 5 or 8. The invention concerns also an arrangement 24, a doorway 29, a building 3 and a lumber drying facility 30.

Abrégé

This invention concerns a method for monitoring of timber 1 that is being dried in a drying arrangement where the method comprises detection of a change in dimension. The detection takes place through reproduction of the extent of the timber during the drying process at least two different points in time in order to obtain at least a first and a second reproduction that demonstrate the extent of the timber in at least one direction, measurement of the extent of the timber on the first reproduction, measurement of the extent of the timber on the second reproduction, determination of the difference between the extent of the timber on the first reproduction and the extent of the timber on the second reproduction and thus the determination of a change in dimension, and the relation of the change in dimension to the expulsion of moisture from the timber, the drying process of the timber, when the change in dimension demonstrates a reduced extent, shrinkage, of the timber. The invention concerns also an arrangement (2) and a drying arrangement (11).

Abrégé

This invention concerns a method for determining the moisture content of wood (2) that is being dried comprising the introduction and placement of the wood into a chamber (3), the introduction of flowing warm air into the chamber (3) and onwards round and past the wood (2) and expulsion of the moist air, and thus also expulsion of the water that has been emitted from the wood (2), from the chamber (3). The method is characterised by the sending of a pulse through the wood (2), from one side of the wood (2) to the other side, the reception of the pulse when it has passed through the wood (2), the measurement of the time of transmission for the pulse from its transmission until its reception, and calculation of the moisture content of the wood relative to the time of transmission, where a long time of transmission of the pulse is related to a high moisture content of the wood and a short time of transmission of the pulse is related to a low moisture content of the wood. The invention also concerns an arrangement (1), a drying chamber (3) and a drying plant (8).

Abrégé

The invention concerns a method for the dynamic control of the drying period in a drying tunnel that works with an outwardly enclosed drying pathway (1) through which wood in the form of batches (4:2-4:n) is fed forwards at regular intervals, known as the 'throughput time', such that a batch of wood (4:0) with its load of moist wood are fed into the pathway at the same time as a batch of dried wood (4:n) and with a moisture ratio (൘n) that has been achieved and that is located at the innermost extent of the drying pathway is fed out from the pathway. The method is characterised in: that the final moisture ratio (ϑn) for a batch of wood (4:n) located at the innermost extent of the pathway (1) is determined by measuring the moisture ratio of the batch of wood, that the measurement of moisture ratio is carried out directly in the drying pathway, that the final moisture ratio (ϑn) is compared with the target moisture ratio (൘n) for the batch of dried wood, that withdrawal is carried out if the final moisture ratio (ϑn) is less than or equal to the desired target moisture ratio (൘n) for the batch of wood.
