Environment Friendly High Humidity Material Industrial Drying Equipment
Material Description:
High humidity material generally refers to the material with the water content of 50%-80%, the common
high humidity materials include pork / chicken / cow manure, bean dregs, drug residue, cassava dregs,
lees, fructose powder, soy sauce and vinegar residue, etc., it’ll need to be dried to the safe storage
moisture-13%, if you want to make rational utilization of these materials.
The most traditional disposal way of the livestock manure is to sell as farmyard manure with the low
price and be used directly as the agricultural fertilizer, its economic value is not to fully explored and
utilized. In fact, these are the precious fodder and fertilizer resources, if it can be developed and utilized,
it will have great significance to the organic fertilizer manufacturing, to the development of planting and
breeding industry, to promote agricultural production and income, energy saving and pollution-free green
food, green agriculture development, to environmental protection and people's health. It makes use of
waste to produce useful material such as fertilizer.
Process Flow:
The dewatered material will be transported to feeding head of the dryer through the screw conveyor after
scattering, and then it will be sent into the inside of the dryer through the unpowered spiral sealing
feeder (the patent technology of our company), and going through several following working areas after
getting into the dryer:
1. Material leading-in area
The material will come into contact with the high temperature negative pressure air after getting into this
area and plenty of water will be rapidly evaporated, and the material can’t be formed into sticky stuff
under the stirring of large guide angle lifting plate.
2. Cleaning area
The material curtain will be formed while the sludge is lifted up at this area, and it will cause the material
stick on the cylinder wall while it’s falling down, and the cleaning device is installed at this area (Lifting
style stirring plate, X type second time stirring plate, impacting chain, impacting plate), the material can
be quickly removed from the cylinder wall by the cleaning device, and the cleaning device can also
crush the materials which are bonded together, so as to increase the heat exchange area, increase the
time of heat exchange, avoid the generation of wind tunnel phenomenon, improve the drying rate.
3. Inclined lifting plate area
This area is the low temperature drying area, the slime of this area is at the low moisture and loose
state, and there is no adhesion phenomenon at this area, the finished products reach the moisture
requirements after the heat exchange, and then enter the final discharge area.
4. Discharging area
There aren’t stirring plates at this area of the dryer cylinder, and the material will be rolling to the
discharging port.
The material gradually becomes loose after drying, and discharged from the discharging end, and then
sent to the designated position by the conveying device, and the fine dust drawn out along with the tail
gas is collected by the dust collector.
Hot air enters into the drying machine from the feeding end, and the temperature is gradually reduced at
the same time of material convection heat transfer, and the water steam taken out under the suction of
induced draft fan, and then emitted into the air after processing.
System Advantages:
New internal structure strengthens the cleaning of dispersed material and heat conduction, eliminate the
sticking phenomenon of the barrel body’s inner wall, it’s more adaptable to the material moisture and
stickiness, the heat exchanging area and the drying efficiency are increased. The operating parameters
can be changed according to different materials, and the heat exchange of the material in the dryer is
more fully. The coal, oil, natural gas, liquefied petroleum gas can be used as fuel. It’s determined
according to material requirements and local natural advantages, to improve production efficiency and
economic benefits. The PLC automatic control system can be adopted in the entire system, the system
contains advanced testing equipment: temperature measurement, temperature regulation (it can be
adjusted at any time according to the needs of the material), the function of automatic fault alarm,
automatic shutdown protection, etc.
