Stainless Steel High Humidity Material Industrial Drying Equipment  For Drug Residue

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.

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:

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

benefits.

4.Anti acid/alkali corrosion

Stainless steel high humidity material industrial drying equipment can prevent from acid/alkali corrosion

and iron contamination.
