Definitions
- the present invention concerns a drive-through chamber type timber drying kiln, where the timber loads to be dried are conveyed on a roller track or equivalent through a front door into the drying kiln, and from which drying kiln, subsequent to drying, the timber loads are removed on the opposite side of the drying kiln through a back door.
- So-called drive-through chamber type drying kilns are known in prior art. Their structure is such that drying kiln loads assembled of drying kiln packages are carried into the drying chamber on a roller track in front of them, whence the loads are pushed into the drying chamber. The dried loads are taken out through the opposite door of the drying chamber. It is an advantage of these chamber-type drying kilns known in the art that in them the load changing time is comparatively short. However, a disadvantage is the expensive realization of such drying kilns, because they require two opposite doors, and roller tracks on both sides of the drying chamber.
- the object of the present invention is to provide a simple design by which the drawbacks mentioned can be substantially reduced, and to provide a chamber-type drying kiln in which the advantageous characteristics of the chamber-type drying kiln, mentioned above, are preserved.
- the invention is mainly characterized in that in the drying kiln two or more drying chambers are connected in series and that of these chambers connected in series each chamber operates independently in the way that when the timber loads are transferred from a first. chamber to a next chamber, in this latter chamber the drying is carried on substantially from that point of the drying schedule which had been reached in the drying process in the first chamber.
- the chamber-type drying kiln comprises four drying chambers K 1 , K 2 , K 3 and K 4 .
- the chambers K 1 and K 2 among themselves and the chambers K 3 and K 4 among themselves are connected in series.
- the chambers K 1 and K 2 in ombination and the chambers K 3 and K 4 in combination constitute two chamber groups, both of them having only one front door 11 and one back door 13.
- Through the chamber groups K 1 , K 2 and K 3 , K 4 pass the roller tracks 10.
- the initial parts 10a of these roller tracks are located outside the doors 11, and similarly the ultimate ends lOb of the roller tracks 10 are located outside the rear doors 13.
- the timber loads P 1 to be dried are brought to the initial ends 10a of the roller tracks, and the finished dried loads P 4 are taken off the ultimate ends 10b of the roller tracks 10.
- the chamber-type drying kiln comprising two drying kiln groups is composed of outer walls 14 and partitions 16, of a roof 15, and of the front doors 11 and rear doors 13 mentioned. Between the first chambers K 1 and K 3 and the second chambers K 2 and K 4 are provided light-weight partitions 12, for instance made of flexible fabric-type material, because these partitions 12 need not be thermally lagging.
- the partitions 12 are advantageously of such kind that it is possible to push the drying kiln loads P 2 through them from the first chamber K 1 , K 3 to the second chamber K 2 , K 4 .
- Each drying chamber K 1 -K 4 is provided with means by which circulation F k of drying air through the timber loads P a and P 3 composed of packages provided with spacers is achieved.
- Said means comprise one or more blowers 20 and a heating radiator 21 placed in a duct 22.
- On the intake side of the blowers 20 in the duct 22 is introduced through ventilation ducts 26 an inlet air flow F in from outdoors, and similarly, on the pressure side of the blowers 20, an outlet air flow F out is taken off through ventilation ducts 25.
- control dampers 23 and 24 are provided in connection with the ventilation ducts 25 and 26 to control dampers 23 and 24, by the aid of which, combined with regulation of the radiators 21, the drying capacity of the circulating air F k is influencable.
- Said means are separated from the load space by a partition 17, which is open on both sides (apertures 18 and 19). Through one aperture 19 the circulating air can pass to one side of the load, and through the other aperture 18 it is enabled to return to the blowers, having in the meantime passed through the loads.
- the direction in which the air circulates is reversed at regular intervals, usually automatically.
- the drive-through chamber type drying kiln described in the foregoing operates as follows.
- the first chambers K 1 and K 3 and the second chambers K a and K 4 of the chamber groups operate independently.
- loads P 2 are transferred from the first chambers K 1 , K 3 into the second chambers K 2 , K 4 , drying is carried on subsequent to this transfer as if no transfer had taken place, in other words, after the transfer, one begins to follow the drying schedule in the second chambers Kz,K 4 starting at that point in the drying process which had been reached in the drying in the first chambers K 1 , K 3 .
- each group of chambers contains two drying chambers K 1 , K 2 ; K 3 , K 4 , In certain applications there may be even more such chambers in series, for instance three or four.
