Steam wood dryerIntroduction:

Steam wood specific dryer, capable of drying various types of wood and various specifications of wood. It has the advantages of high efficiency, energy saving, reliable cases, short drying cycle, good drying quality, and low drying cost. It is widely used in large, medium, and small wood processing enterprises, especially suitable for operating wood processing manufacturers. The Maichuang series wood specific dryer uses a steam generator to generate sufficient heat energy during normal operation, which is fully absorbed by the drying medium in the heat energy drying system, producing a temperature of about 50-120 degrees Celsius. Under the action of the circulating fan, the high-temperature air circulation process is required. Saturated wet steam can quickly make the surface temperature and internal humidity of wood consistent, thus achieving the goal of drying both the inside and outside of wood simultaneously. By using intermittent heating drying technology for wood with different individual sizes, defects such as internal cracking, end cracking, and deformation during the drying process are solved, greatly improving the yield of high-quality wood products. The wood drying equipment is equipped with a heat recovery system, which significantly reduces the drying cost and shortens the drying cycle. When the moisture content of the wood drops below 30-35, after high-temperature dry steaming, all parasitic insects and their eggs inside the wood can be eliminated, solving the adverse effects caused by insects and improving the economic efficiency of the enterprise.

1、 Equipment composition

The steam wood dryer uses steam as its energy source, and the steam pipes inside the equipment are composed of components such as pipelines, steam traps, radiators, and boilers.

2、 Working principle:

The heat dissipation of the drying room radiator is related to its surface area, and the size of the heat dissipation area can be calculated. The manufacturer uses high-quality seamless steel pipes and aluminum fins on the surface to increase the surface area of the radiator and improve the heat exchange efficiency. By using electromagnetic valves to regulate the temperature inside the drying room, the cost of manual control has been reduced and the quality of drying has been improved. Reasonably adjust the hot air ventilation volume, evenly ventilate layer by layer, provide all-round hot air supply, no dead corners, so that the wood can be uniformly and uniformly dried, and run efficiently. Reduced the occurrence of wood deformation, internal cracking, and end cracking.

3、 Performance characteristics:

1. Using a high-temperature and high humidity axial flow fan to perform heat exchange on the surface of the finned radiator, as the area of the finned tubes on the radiator surface increases, the temperature distribution inside the drying room is relatively uniform through the hot air circulation system.

2. The steam is converted into clean hot air by a steam boiler through steam pipelines and introduced into the wood drying room. The high temperature and high humidity resistant axial flow fan in the drying room is used to achieve uniform drying of wood in various areas by hot air. Heat recovery and utilization are achieved by repeatedly heating the hot air in the drying room through a hot air circulation system. Thus reducing the cost of use, it is a relatively economical equipment for wood drying and drying in China.

3. The steam boiler separates the combustion chamber from the hot air system, providing pure hot air without any pollution to the wood. Eliminating the risk of igniting materials inside the drying room and causing safety issues such as fires that may occur during traditional wood drying.

4. The hot air temperature can be adjusted according to different types of woodThe needYes, it can be adjusted and controlled between 35 ° C and 100 ° C, achieving drying of various hardwoods, hardwood, cork, veneer, wooden boards, plywood, etc. This is achieved by controlling the steam input through an electromagnetic valve, with small temperature difference, fast drying speed, and high quality.

5. Using a steam wood dryer, it can dry to the required final moisture content without being limited by natural conditions. It has mature drying theory and process technology, which can ensure drying quality. Compared with air drying, it has a shorter drying cycle, higher production efficiency, smaller footprint, less complex equipment, long service life, safety and reliability, and good economic effect.

6. By using a moisture removal system to achieve forced moisture removal, the emission of exhaust gas can be accelerated and the drying speed can be accelerated.

7. In the production process of drying equipment, the hot air system of the steam pipeline mainly heats the radiator wall with steam, and then transfers the heat to the cold and humid air through the wall. After the steam in the pipeline releases the heat of vaporization, it will form condensed water and then be discharged.

Notes:

When using a steam pipeline system to heat the drying room, we need to promptly drain the condensed water, otherwise it will accumulate in the radiator, not only reducing the heat dissipation area, but also affecting the normal operation of the steam wood dryer, and even exacerbating pipeline rust. Therefore, the steam outlet end of the radiator will be equipped with a steam trap, which is mainly used to separate water and gas. Steam pipes are evenly connected to the drying room. The heat transported by the steam pipe is uniform, and the insulation layer is filled with high-density aluminum silicate cotton, which ensures the insulation of the oven and the safety of the user.
