hot grain rotary drum drying line price/drums dryer machinery for sale

 hot grain rotary drum drying line price/drums dryer machinery for sale Structure and Working principle 

hot grain rotary drum drying line price/drums dryer machinery for sale  DETAILS

Material goes through the feeding device into the lining of the drum, in order to realize the downstream drying,

material inner constantly grabbed, scattered under the copy board of a spiral rolling to realize heat exchange, the material move to the other side of the lining and into the middle side, at this time going counterflow drying, material in the middle are constantly repeated by copy board, it is marching into two steps forward and one back, material in the middle is fully absorb heat coming from the inner cylinder, and absorb the middle roller heat and prolong the drying time again at the same time, at the moment dry material is at the best condition.

 The Material go to the other side of the middle section and into the outer section, material within the outer cylinder in rectangular loop travel ,  in order to achieve the material moving fast to discharge roller under the effect of drying in hot air . Because of  the weight other wet material can't advance rapidly drying, the material returns to this rectangular copy board  with fully drying action, in this way hot grain rotary drum drying line price/drums dryer machinery for sale  can achieve purpose of drying.

 hot grain rotary drum drying line price/drums dryer machinery for sale ADVANTAGES:

 Reliable technology
1.material at head of the tube goes into the inner cylinder, under the action of copy plate the material back to  the middle barrel, once again back to the outer barrel, finally dry material is discharged from the other end of the barrel, the length is three times as that of the traditional dryer, thus it greatly reduced the volume of the equipment.
2.Rotation speed controlling system can be adjust according to the different materials , little abrasion, safe and reliable, low maintenance cost.
3.The feeding speed can be adjusted,simple operation.
4.Large capacity , continuous operation.
5.Advanced explosion-proof fire system design, safe and convenient.
Energy conservation and high efficiency
Because of the special structure of corn grain drier, materials in the middle barrel and the outer barrel

become more spread , fully exposed to air, heat exchange area is larger, at the same time because the external heat is transferred step by step from the inner barrel to outward , it can make full use of the waste heat and reduce the heat loss.Thermal efficiency is increased by 30% - 40%; Volumetric heat transfer coefficient is twice of the  single cylinder dryer.
 High automation
The hot grain rotary drum drying line price/drums dryer machinery for sale  can automatically finished feeding and discharging process. Exhaust temperature adopts intelligent control, and linkage with speed-control feeding device, the feed-rate can be automatically controlled, in order to make sure the dryness of the product. It saves energy consumption, as the exhaust temperature is 50-80℃.
Good appearance after drying.
Professional furnace design can make the fuel in the furnace chamber burn adequately, furnace contains several  settling chamber, hot air discharge from furnace at a rather slow speed, furnace slag are blocked and dropped in  the settling chamber ,in this way it ensures the purity of the high temperature air, under the condition the material  doesn’t have black spots phenomenon.
