Wood shavings drying methods in bulk production

For the production of dry wood shavings, the best wood shavings drying methods in bulk production is to use triple pass rotary wood shavings dryer machine.

Triple Pass Rotary wood Shavings Dryer Machine adopts advanced technology from China, and it can dewater and dry the wet wood shavings in large quantity from moisture content 40-50% to less than 13%. The dried wood shavings can be used as animal bedding, or produce chipboard, etc.

What is the working Principle of Triple-pass rotary Wood Shavings Dryer :

Wet wood shavings pass through the triple-pass wood shavings dryer cylinder in an hot air stream created by the Induced Draft Fan. The three drum are concentric and are mechanically interlocked to rotate at the same speed.

The wet wood shavings 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 of the wood shavings drying system, without product degradation. Controls react instantaneously to any temperature change, and immediately adjust the heat input to assure uniform drying of wood shavings and accurate control of the moisture content of the finished product.

After that, to use vibratings screen to classify the wood shavings into different size ranges as need, meantime to get rid of the fine wood powder.  Finally to pack the wood shavings into bags as need.
