Timber drying kiln

Leading wood drying equipment from China, economical and reliable performance.
PARLICULAR DETAILS
1. BEARING STRUCTURE
The structure of the kiln is made completely of special aluminum alloy AW6063. All the beams, profiles, and roof holding structure as well as wind-bracing have high resistance to corrosion, which are of I, U, L & C .
The complete structure is self-supporting and is mounted on to a base concrete foundation using stainless- steel heavy-duty dowels.
The connecting materials, bolts, nuts &washer are made of stainless steel. The offered bearing structure can bear stress of 150kg/m2 of snow load and wind load of 120km/h.

2. KILN CASSETES SHEETING AND INSULATION SYSTEM
The heat insulation system is made of aluminum cassette-panels of alloy with high density non-flammable rock wool thermal insulation of 120mm thickness, the density of rock wool is 55kg/m3, which is higher than that of fiberglass. There is a slope on the roof, avoiding accumulation of rain or snow on the roof. The kiln wall is externally and internally faced with corrugate embossed aluminum sheets with a granulated finish of 1.1 mm. The Cassettes themselves are specially mounted with the supported of aluminum plate between columns of bearing structure. High-temperature caulking between cassettes protects the walls from heat transfer. The caulking is applied at any cassettes joints.
The thermal constant of the jacket penetrability is k=0.45w/m-2.k-1. This is due to the particular construction characteristics of the walls. They are completely fire resistant; they do not absorb moisture, guaranteeing constant operation.

3. KILN DOOR
The lifting –sliding sturdy aluminum door structure profile. The special groove where the strong rubber seal is installed provides optimum tightening alongside the doorframe. The kiln door wall is of the same construction as the kiln and roof walls using rock wool insulation of 120mm.The closing system is equipped with adjustable counterparts which enable the precise adhesion of the door to the kiln structure. The bottom mullions feature nylon rollers on heavy duty

stainless pins

4. KILN DOOR CARRIER AND LIFTING DEVICE
The TECH I’ beams monorail carriage design realizes unrestricted movement of the door which hangs vertically in its raised position. Carriage wheels are sealed ball bearing to in any weather conditions.



5. INSPECTION DOOR
The inspection door is included and is of opening 1500×600 mm
with rock wool insulation of 120mm.
It is equipped with a safety handle, easy to open and close.
The inspection door will be placed in rear wall.



6. FALSE CEILING
The chamber is divided by aluminum intermediate ceiling into a technology section where all the technical elements are located and a drying section where the timber to be dried is placed. The intermediate ceiling is mounted on the lower part of the chamber beams and is made of corrugated profile sheets of thickness1.1 mm ensuring the smooth air flow.



7 FANS & MOTORS
The air ventilation is provided by reversible medium pressure fans with high performance level installed in each chamber above false ceiling of the chamber. The fans can perform with the same efficiency and capacity in both direction and at any revolution rate. Each fan has 6 aluminum swinging blades with perfectly symmetrical shape. The aluminum fan φ800 mm impellers are fixed directly on to the shaft of the specially designed motors. The motors are tropically insulated to resist high temperature (IP55) and to work without any problems in environments reaching 100% of moisture content


8 HEATING ELEMENTS
The heating elements use aluminum fin built on stainless steel pipe. Heat exchanger coils are located vertically overhead. All the piping from collectors for the heat exchanger coils up to flanges out of kilns are made in stainless steel. The heat output is designed for the highest demand.

9. THE AIR EXCHANG SYSTEM
The ventilation and suction system of vents are made of aluminum material. Vents make use of pressure and vacuum zones generated inside the chamber which avoids the use of additional fans. The whole system of vents works simultaneously. In this offer the chimney are provided in the chamber ceiling. The vents are positive opening and closing.


10. ELECTRIC BOARD
The board is the modular panel meeting the international standards relevant to protection class IP55. The operating drying components are placed in the electric board. (Switches, relays, fusing etc.)

11. AUTOMATIC CONTROL OF THE DRYING PROCESS HOLZMEISTER M800B (DELPHI)
Every unit is equipped with:
6 pcs of probes to detect the wood moisture
2 pcs of EMC stations/ front and back / For climate controlling
It is a LCD based automatic kiln controller. The kiln dryer controller DELPHI is based on the most advanced electronic technology today available and includes all the best solutions that LOGICA H&S has developed in over ten years of experience in timber drying control systems.
The new user interface, based on a LCD graphic display having a very good readability, allows an easy set-up also to not skilled users, because all setting are made through self-explaining menu and the access to most advanced menus, divided from the ones most commonly used.
