The working grain dryer


Tower drying machine is widely used in the field of wheat, rice, soybean, corn, and peanuts; we could provide different kinds of machines to meet the special need of clients. The structure of the tower drying machine is very simple and easy to operate, which is very popular in the big farm, grain procure station, grain raiser. The machine uses coal and straw as fuel, refrain the grain from pollution with small investments, and full automatic operation, which is suitable for the big or middle farm. The abandoned rice husk, firewood, straw, all of these can be used as the fuel materials, which save the expenses for coal or fuel gas , clean hot air for drying material without any pollution.

The grain dryer of working Principle

The grain which have been cleaned,send to the dryer tower by elevator,stockpiling on the storing grain prothole by dead-load,stop load material.Fire hot blast furnace,close draft fan cooling resist,open draft fan hot blast resist,open draft fan supply heat air.After one hour start the row grain cycle facility,the grain will be Uniform distribution cycle move,contact with hot blast then heater,the moisture of the grain will be discharge from inner to outer,till reach dryer requirement.Then open the below fast row grain hole make the grain out of the dryer.After finished dryer,High moisture grain,it is control the reduce moisture scope according to the requirement.Single tower cycle dryer is batch cycle,have dry and cooling functions design.Dual-tower combined type,composition by the heat-cool tower and Dual-tower.Tri-tower or Multi-tower combination,composition by plural heat tower and one cooling tower, it is continuation working type,it can be satisfied with different variety reduce moisture 0.5-6% for one time,if reduce moisture more than 7-20%,it will be reduce the capacity.
