Our company may design and manufacture the brickwork-type, colorful steel plate-type, metallic shell type and full A-alloy assembling type timber drying equipment according to the requirement of user, with 20-200 m3 for timber loading quantity; the control modes cover the manual control, semi-automatic control and full-automatic control; the heating media covers the steam, hot water and heat transfer oil. Guarantee the excellent product quality, advanced technology, reasonable price, and timely supply of goods and good services as well as lifelong tracing service. The products of our company are divided into following kinds:

KILN STRUCTUTE:

 Skeletal system of the kiln is consisted with aluminum frame which is a special-shaped aluminum profile developed and designed by HuaHai. Stainless steel bolt is used to connect aluminum profiles and aluminum plates. The joint is sealed with special sealant to ensure the tightness of kiln. The aluminum plate in the kiln adopts the aluminum flat plate and the grooved aluminum plate structure, and the outer aluminum plate adopts the 750-type large corrugated aluminum plate, which has good rigidity and beautiful appearance. The inner and outer plates of the kiln wall are filled with large bulk glass wool insulation, and the heat preservation effect is excellent, effectively reduce the heat loss of the drying kiln during the working process.

The overall appearance of the kiln is sturdy and durable, which can ensure normal operation in harsh environments such as wind load and snow load in alpine regions. 

 In the way of pressure dehumidification, the dehumidification cylinder is arranged symmetrically on both sides of the fan, and the dehumidification is carried out through the pressure difference of the circulating inlet and outlet end of the fan. The wet bulb in one side discharges the humid air in the kiln, and the other side draws in the dry air from the outside.  The dehumidification system is composed of dehumidification tube, connecting rod and electric actuator of air valve. The air valve electric actuator adopts Siemens from Germany, and its performance is stable and reliable.

DEHUMIDIFICATION SYSTEM 

 In the way of pressure dehumidification, the dehumidification cylinder is arranged symmetrically on both sides of the fan, and the dehumidification is carried out through the pressure difference of the circulating inlet and outlet end of the fan. The wet bulb in one side discharges the humid air in the kiln, and the other side draws in the dry air from the outside.  The dehumidification system is composed of dehumidification tube, connecting rod and electric actuator of air valve. The air valve electric actuator adopts Siemens from Germany, and its performance is stable and reliable. 

 

HEATING AND SPRAYING SYSTEM

  In the wood drying process, the heating and humidification in the kiln are realized by the heating and spraying system. The steam heat source realizes the thermal cycle of heating in the kiln through the control valve group, the connecting pipe, the radiator and the return valve group..Humidification is carried out by steam spraying valve group and spraying pipeline. Steam is sprayed to the kiln through the steam spraying hole of the spraying pipeline in the kiln, and the humidification process is also a heating process. High quality electric valve is used for control of heating and steam spraying, with accurate control and stable performance. Backwater adopts floating ball trap, which can effectively reduce heat loss and increase the utilization rate of heat energy. 


 

CONTROL SYSTEM

      The controlling system is mainly divided into two kinds: semi-automatic control and fully-automatic control. The meter changes the temperature and humidity in the drying kiln by controlling the switch of the valve. Temperature control is realized by controlling the change of heat source transfer in the heating system of the kiln by electric valve switch. Humidity is achieved by controlling the spraying electric valve and the air valve electric actuator. 

      Semi-automatic control: can also be called phase automatic control, automatic operation of equipment in each drying stage. The drying stage is determined by different wood drying processes and the drying process value is set by the drying technicians themselves. After setting, the equipment runs automatically. 

      Fully-automatic control: operation technicians can wood drying process or directly select the inherent wood drying process in the control instrument for wood drying. The automatic control system carries out automatic detection of temperature, balance moisture content and wood moisture content in the kiln according to the or call of the drying process procedure, and guides the kiln to heat and drain moisture in accordance with the detected data to achieve the wood drying effect.
