grain rotary drum dryer

1)dry all kinds of grains 2)dry about 200T in 24 hours,but can be custom made with bigger or less capacity 3)full automatic

main feature

Breakthrough in Grain Drying Technology. The Relative movements of Grain and Air in the Drying Zone, producing"MIXED-FLOW" characteristics resulting. Tailored for high capacity grain drying, ranging from 100 Ton/Day to over 400 Ton/Day.(also according to customer's need)

1,The latest technology and revolutionary computerized touch screen controls.Controls are by way of a touch screen interface through a Programmable Logic Controller (PLC).:there are testing sensor transferred the the moisture and grain temperature to the computer control center,which are tested by testing sensor timely. Through Computer program operations to control the following :

1)automatic control of raw grains input

2)hot air stove of accurately controlling for automatic

3)the control of hot air and temperature for different section

4)with temperature-based automatic moisture control.

4)the control of the air volume for output

5)Automatically adjusts dryer unloading speed to maintain grain discharge moisture.

6)Includes built-in control diagnostic,auto shutdown

2,Efficiency, energy saving, environmental protection, and drying grain good quality, low cost

The hot air stove of efficient and energy saving,can buring different fuel,including coal ,husk ,oil,grease and gas,etc.(we design according to the customer's needs);

Standard boiler with two- story layout Furnace,which is fire-resistant and energy conservation,the advanced .Furnace make the fuel can burn more and well, and environmental protection and no pollution, the service life is long.

Take advanced multistage drying equipments,Unique dust removal technology with thefunction of Focus on absorption of dust, waste gas,as well as the function of Multi-level spiral falling dust, water curtain dust,so can achieve environmental pollution.

Computer control system can control the hot air,temperature and the speed of unloading dynamically according to the grain moisture. Drying medium gathered with the grain of low temperature and high moisture in the (the up- and down-stream )mix flow tower,at the same time ,flowing to the same direction,which not only can best use of the high temperature hot air,bus also can makeeach grain get the same temperature and average dying for each grain,however,the maximum heating temperature for the grain itself is lower than 50 °C,After each drying section, taking the easy process ,so that moisture dying tend to balance and also Benefit for next drying section and make sure drying quality.Practice shows that compared with other drying models,Can save energy 30-50%
