Abstract

The invention relate to wood processing engineering, in particular to sawn timber drying process, including thick-walled and round logs, with the aid of vacuum-impulse action performed on timber arranged in sealed drying chambers. The inventive method for drying thick-walled timber and logs consists in supplying steam to said drying chambers (1, 2), equalising humidity along the cross section of said sawn timber (28) inside and outside thereof and in heating the timber. Said operations are carried out with the aid of air ducts (23, 24) circled by sections, fans (20), distributors (24), air heaters (21) and guiding elements (25, 26,27) which uniformly distribute a flow through the height and length of stacked sawn timber (28). The distribution of steam and a wood syrup saturated steam-air mixture is carried out in two operations i.e. at first, in diffusers arranged between the fans (20) and the air heaters (21) and, afterwards with the aid of the guiding elements (25, 26,27) on at least two levels. The inventive method for drying thick-walled timber, i.e. beams, logs etc makes it possible to avoid the occurrence of stresses, cracks or warping of wood.

Widely known installations for drying wood, containing

2. Imperfect camera with a hermetically closing two doors and a hot air vent with a fan supplying heated air to the camcorder.

The drawbacks of such wood drying plants are the lengthy process of adding wood to wood from 8 to 20 days, depending on

Z. Waste wood, low drying quality, unequal depth of moisture in dried wood, moisture in the wood is accelerated, so that it is removed,

A better installation is known to be available at home.

4. There is a process of drying of solid materials with the use of a vacuum and a large number of heating units with a heating unit.

A well-known installation contains a drying chamber, a vacuum pump that is also connected to a solution of waste and the use of pipes and valves.

5. See A.S. СССΡ Г ° 1000701, κl. Ρ 26V 5/04, ηubl. 1981 year Β A well-known installation for drying wood in every cycle between heating and vacuum has an adiabatic production, it is a good product. Blowing osu-

SIGNIFICANT FOX (DR. 26) 2 are a gas-air mixture with a temperature of 160 C and 6. Humidity of 15 g / kg for 6 minutes at atmospheric pressure.

The accumulator is supplied for two minutes at a constant pressure of 300 mm. ρτ. ct.

The well-known system and devices have a large energy output, a long process time and low waste weight.

There is a known better technical solution - the simplest is the installation used to realize the process of drying the wood by-pass 20. cl Ρ 26 Β 5/04, Ρ 26 V 3/04.

8. The installation has a heated drying vacuum chamber connected through a quick valve of a vacuum system with a vacuum. A combination of the volume of the drying chamber and the volume of the receiver for creating a vacuum of the required depth must be at least 1: 10.

9. The wood is loaded into the drying chamber, it is easily closed and heated. At the same time, in the case of a vacuum, a vacuum is generated, after which there is a sudden discharge - an impulse - pressure in the drying chamber, is emptied. After this

10. The wood in the drying chamber supports vacuuming, which is stored in vacuum and is separated in the course of time. Then the drying chamber emits vacuum from the vacuum chamber and connects it to the atmosphere and discharges the heat from the inlet to the vacuum chamber.

11. The indicated operations make it possible to achieve many benefits.

SIGNIFICANT FOX (DR. 26) 3 set the humidity of the wood. The depth of the given vacuum in the process of pulsed vacuum is created due to the solution, which has an increase in the volume in comparison with the full volume of the drying chamber. INSTALLATION ALLOWS TO REALIZE THE METHODS OF DRYING
