Wood Chips Dryer From Zhengzhou SunCo Machinery:   Zhengzhou SunCo Machinery has been worked in the drying of wood chips, sawdust, wood shavings since 1990. From then on, we have seen many different drying methods with varying degrees of success. Our experience has proved that the most cost-effective and efficient method for drying wood chips is to use of rotary drum dryers.

Wood Chips Dryer From Zhengzhou SunCo Machinery can dry moisture 40-50% wood chips into about moisture 12%. The moisture inside the wood chips mainly are free water and biological water. Free water is easier to be dewatered, and biological water is difficult to be got rid of.

Wood Chips Dryer From Zhengzhou SunCo Machinery is the Ideal Method to dry wood chips. This simple, direct, and highly effective method of drying has been successfully applied in the dewatering of a wide range of materials; and has proved to be the ideal method for drying wood shavings and wood chips. The drying drum features an expanding cross-sectional area and a compound showering flight pattern which guarantees maximum exposure of all particles to the drying medium. The velocity and temperature of the air stream are different in each of the three passes to suit the changing rates of evaporation as the moisture content of the wood shavings and wood chips decreases.

Wood Chips Dryer Composition: Hot Air Furnace, Rotary Drum Dryer, Screw Conveyor,  Belt Conveyor , Dust Catcher,  Induced Draft Fan,  Air duct tube, motors, etc.

How Wood Chips Dryer works ?
Material moves through the triple-pass drum in an air stream created by the wood chips dryer’s Induced Draft Fan. The three cylinders are concentric and are mechanically interlocked to rotate at the same speed.

The wood shavings or wood chips are repeatedly carried to the top of each cylinder by internal and external flights so they are constantly and intimately showered through the hot gas. Moisture is given off continually as they move along the hot air stream.

Heavier, wetter particles move slower than fine particles -- forward through the center cylinder, back through the middle cylinder and again forward through the outer cylinder to the induced draft fan at the discharge end. The warm damp exhaust gases are separated from the dried product in the primary cyclone separator, and fall out the bottom onto a vibrating shaker screen to remove fines. (Note that the optional secondary "cooling fan" and cyclone collector, which under favorable ambient conditions can remove several additional points of moisture.)

Precise control of exhaust air temperature assures accurate moisture control, without product degradation. Controls react instantaneously to any temperature change, and immediately adjust the heat input to assure uniform drying and accurate control of the moisture content of the finished product.

If the product is fragile, a "negative air" system may be used, where an airlock is installed at the bottom of the primary cyclone collector and the induced draft fan is positioned downstream to avoid product breakup caused by passing through the fan. However, we do not recommend this arrangement with certain species of wood, since we have found that resins present in the warm damp exhaust can quickly accumulate on the sidewalls of the pipe and plug it, making for a difficult cleaning job.

Features of Wood Chips Dryer from Zhengzhou SunCo Machinery:
1- More economical to operate when fuel costs are taken into account. Cost savings of 60% -70% are not uncommon.
2- Big drying intensity. As wood chips (or wood shavings) are high dispersion inside the flue gas, all superficial area of the wood chips (or wood shavings) are the effective drying area.
3- Short Drying Time
4- Simple Structure, Less occupied area, easy installation and maintenance.
5- Large Capacity, High Heat Efficiency.

How to select the suitable wood chips dryer ?
We need know these information as follows:
1- Before drying, what is the moisture of the wood chips ?
2- After drying, what is the moisture of the wood chips ?
3- How many tons wet wood chips do you need to dry per hour ?
4- What fule will you prefer to use, such as coal, diesel, natural gas, waste wood, etc ?
