Introduction to the Equipment
Control System
The controller model Delphi is a modern electronic device, made with the newest materials, which is able to do, in a totally automatic way, the complete drying cycle required by a large number of timber groups. The project of this system has been realized in order to couple the most advanced functions with the easiest simplicity of use: there is one special key for each function that can be recognized by a symbol. Furthermore, to simplify the operations, a new system based on chip-cards has been introduced, which allows the user to record on cards the most used programs, personalized according as the type of kiln dryer and the timber group, which can be set up on the machine only by inserting the card into the card reader.
Technical Specifications:
Measurement and Control Range of Temperature: 0-100ºC
Measurement and Control Range of Humidity: 3-30%
Measurement Range of Moisture Content of Wood: 4-80%
Heating System
The heating system is composed of electromagnetic heating valve, bimetallic (stainless steel/aluminum) ribbed heat-exchanger coils, cut-off valve and piping.
The heating system can meet different drying requirements from medium-low temperature schedule to medium-high temperature schedule with its strong heating power.
Spray System
The spray system is composed of spraying valve, cut-off valve, stainless steel spray pipe.
The spray pipe is made by stainless steel so that the carbon steel pipe's drawbacks of heavy corrosion and short service life can be effectively avoided.
Air Circulating System
The optimum model of kiln is adopted with circulating fans located on the upper side of the kiln. The No. 8 fan is aluminum molded with big air volume and high efficiency. The electrical power for a single fan is only 3.0Kw so that the energy consuming and the drying cost can be substantially lowered. As the symmetrical blades can ensure the same amount of the air volume and the air pressure no matter the fan is in normal direction of rotation or in contra rotation, the reversible fan guarantees the uniformity of air velocity and air temperature at the cross sections of the stack so that the uniformity of the wood moisture content at the cross section of the stack is greatly improved.
The ceiling is built using LF21 anti-corrosion corrugated aluminum panel that its strength, stiffness and corrosion resistance are substantially improved.
Venting System
To realize the fully modulating operation, the aluminum air dampers are controlled by the vents actuator via the driving mechanism and the vents actuator in turn is controlled by the main control system.
Kiln Door System
The popular one-piece sliding aluminum alloy doors are furnished. The door has a welded steel framework with a double insulation using polystyrene. The door is sealed with custom-tailored special-shaped rubber tube which is heat-resisting, anti-aging and highly airtight.
Besides sliding on the top track the door carrier is also supported by a floor rail, which ensures it operate easily, smoothly and steadily.
