Energy Saving Light Material Industrial Drying Equipment For Sawdust
Light material means the powder or small particle material with the density of about 0.4-0.6t/m³, such as
sawdust, bamboo shavings, rice husk, xylose, wood shavings, wood blocks, etc.
Light material is generally with high water content, such as, commonly the saturated water content of
the sawdust is 45-50%, and some of them can reach 60%; The light material is relatively loose, the use
of air transport will not plug the pipeline.
In recent years, with the increasing of environmental resources, the comprehensive utilization of
biomass energy has become more and more important to us. Due to the high moisture content of the
sawdust, broken wood, which leads the incomplete combustion, resulting in that the spark burns the
dust bag at the back of the drying plant, which not only causes the excessive emissions, but also it’s
with high cost to change the dust bag. In the process of producing wood products and biomass fuels
with high burning combustion value, wood chips and broken dregs are required to do the drying process.
After being fed into the hopper, under the function of gravity the raw material will fall onto the belt
conveyor laid under the bottom of the hopper, and then material will be conveyed onto the screening
machine. The massive, strip and other irregular material will be separated out after screening, and
uniform particles will be conveyed to the feeding end of the dryer (The single cylinder or three cylinder
dryer will be chosen as per the service condition) by the belt conveyor under the screening machine.
The feeding end of the dryer is connected with heat source and the discharging end is linked with pulse
air pipes. The fire wall will be setted up in the hot blast stove in order to guarantee the safety of the
drying process, to eliminate the phenomenon of material burning in the dryer, and the heat passing
through pipe will be installed between the hot blast stove and the dryer as the section of heat buffer. The
material will be brought into the diameter-transformed pulse pipe after being dried and the dehydration
for the first time inside of the dryer, which will be in a suspended boiling form at the large diameter of the
pulse pipe, and then it will be quickly dried after contacting with the exhausted heat wind from dryer.
And the material will be driven out of the pulse pipe by strong winds and moved into the first stage
cyclone collector when its water content reaches the design requirement, and 80% of dried material will
be collected, and then get into the second stage cyclone collector after passing through the induced
draft fan to collect the left material. The bag type dust collector can replace the second stage cyclone
The energy saving light material industrial drying equipment has advanced design, which let the material
has the full contact in the dryer, the full surface area of the particles is the effective drying area, and it
has Intensive drying strength. With the pulse air flow dryer, drying time is only half of the regular dryer,
the efficiency of the drying machine is greatly increased. The energy saving light material industrial
drying equipment has advanced structure, with small mall covered area, easy to construct and to do
maintenance. The thermal efficiency can reach 90% when it dries unbound water. The final moisture is
stable (10%-13%) after the regular light material being dried, and the dried material doesn’t contain
impurities. The hot blast stove can be matched with the super temperature alarm, flame monitoring
device, tempering alarm, fuel isolation device, which can ensure the safety of combustion. By adopting
thermal resistant material on surface of shell, so as to prevent heat loss, it reduces fuel consumption,
that is to say, energy saving.
