Environmental Protection Industrial Pork Manure Drying Equipment
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.
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: 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. 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. 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. 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.
1. High thermal efficiency, low drying cost
New internal structure, and strengthen 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.
2. Reliable running, good stability
The new type of feeding and discharging device, put an end to the phenomenon of the plug in
feeding, incontinuity, nonuniform and material return. The "aligning roller device” is adopted by the dryer,
which makes the tug and rolling ring always do the linear contact, and it greatly reduces the abrasion
and power consumption. The “zero horizontal thrust” of the dryer is realized, which greatly reduces the
abrasion of the gear wheel and supporting wheel, the cylinder operation is more stable and reliable.
3. Wide range of heat source using, environmental protection and non-pollution
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
