Dryer for wood with their hands
The problem of maintaining optimal humidity in lumber relevant than among builders, and among the fans something to make in their own carpentry workshop. In this case, drying of the wood at home allows you to save a good idea to buy it, because the dry raw material is always more expensive than wet.
By the way, if you do not have time for construction work, then dry the wood at home or at the cottage is possible even at atmospheric conditions.
Some owners are adapted for this purpose already existing premises hay, barns or other suitable structures. Here, for example, a way out of the situation found one of our forumchanin.
Timakval (party FORUMHOUSE):
I used to dry attic yard (former hayloft) size 10 * 5 m. We expand as necessary, by laying each row. Total 3.5 cubes of different boards. The advantages of this drying place - always a shadow, ready roof and ventilated cool. I took last May of different size boards, rods and bars for a small building. Boards were impossibly from moisture. During lying in the hay (1.5-2 months) in dry fluff. At the same time they are not twisted and arched.
Drying under atmospheric conditions - the process is quite long, and now that we have decided to take a comprehensive approach to this issue, let us Consider the sequence of a home dryer building, allowing more efficient to achieve the required performance humidity. As a suitable premises, we offer you to choose the construction of the required size, and after that you can start working. The room may have dimensions 2 * 3 or 4 * 3 m (possible). It all depends on your needs and scope of activities. But, choosing the building, it should be remembered that in the dryer should be left plenty of space. After all drafts and chaotic movement of air is often negatively affect the quality of the wood.
Construction of the dryer inside of a room
The room is chosen for the arrangement of the dryer must be heated oven or specially installed chimney. Well, if the room will be pre-mounted heater. If there is no, then do not forget to leave room for him.
That's what the project offers a home dryer member of our forum.
Nicholas Valen (party FORUMHOUSE):
Thus, there is a garage with a major water heating as a boiler installed stove with wood and testing. There pipe diameter of 800 mm and a length of 2.2 meters (former airbox with industrial enterprises). The idea is the following: set hermetic cover at both ends of the tube, leaving choke 150-200 mm in diameter for the supply and removal of hot air. Heated air is cooler (for example, automotive heater). Air supply - desktop fan. The tube is loaded 0.3-0.5 cube lumber melted furnace (coolant temperature reaches 90 degrees, think actual feed air warm up to 50-60 degrees).
If you chose the room is too large, then the space, planned to use a dryer, you should make an isolated and sealed. For these purposes, you can use the wooden partitions, insulation, bricks and other materials that help create a microclimate in the dryer. Do not forget that in the chamber, leave the window for ventilation and, of course, the front door. After all, we should not get a hut with no windows and doors.
Fans installed in the space of the drying chamber, will help to create a forced air flow and make the drying process more efficient.
mfcn (party FORUMHOUSE):
Fans desirable to put on the side of the stack, parallel to the barrel of the spacers. Remember that when drying is necessary with every cubic meter of wood evaporate the order of a few hundred liters of water.
To accommodate the lumber in the dryer should be installed special shelves or decks. They can be made of metal - to design able to withstand relatively high loads. Dry wood should be up indicators corresponding to 8-12% moisture. Its measurements are made using a special meter.
Dry wood is necessary, observing certain rules. Otherwise, the material will be hopelessly spoiled and unfit for further use. To do this, the wood should be stacked. And between each new layer should be positioned pads of boards of the same thickness. Forest, packed in a neat pile, never suffer from fungal infections, keep its integrity and excellent consumer qualities.
Lao Czy (party FORUMHOUSE):
Gaskets should be done higher up, was to better air ventilation between the boards. They dry out better. You can bet on the edge of your cut wedges 25 * 30 or 25 * 40. And what is the reason for limiting the height of the stack? To the board did not lead "a helicopter blade," the uppermost layers of boards in a pile lock screws. So I keep the third year of their boards at the cottage in the suburbs. They are in excellent condition!
Freestanding drying chamber
Can be quickly and efficiently drying the wood in a well equipped and separate drying chambers. Construction of such a camera on a scale cottage or suburban area is not always appropriate. After all, such a construction cost is very expensive, and its construction will take away a lot of time.
The construction of such facilities can be quite called the full-scale construction project. In this case, you can not avoid the labor-intensive operations associated with the pouring of the foundation, with the erection of walls and installation of sophisticated equipment. Such a camera will have the circuit shown in the figure.
In such a dryer be located not only essential equipment (heating and ventilation devices), but also an additional automatic control system.
Modes of operation of the drying chamber
Normal operation of the drying chamber does not imply a high heat. A full cycle of works related to the drying of one batch of wood can be divided into several stages.
- The first phase lasts 15 to 20 hours. During this period the air in the chamber is warmed up to 45So. Ventilation is not turned on, and the condensate drops on the walls of the room.
- The second stage lasts about 48 hours. It involves connecting the ventilation and heating of air up to 50 w.
- The third phase lasts until the desired moisture level in the internal structure of timber (8... 12%). At this time, the air temperature rises to 55 Co, exhaust valve is fully opened, and the fans are running at full capacity.
After the humidity reaches the required parameters, discontinue supply of heat. Fans at the same time must remain enabled for another 24 hours. The result is a dry timber, ready for use during the carpentry or construction work.
