Distiller’s Grains/DDGS Dryer

ZJN drying machine can dry above 80% moisture content residues to below 10%. The color and nutrition will be well kept.

Wet distiller grains is automatically transported into the first level cylinder. With the fuction of guiding board and rotary harrow, wet material will spread into the drying room and contact with hot air directly. Through continously lifting and spreading and hot air blowing, the water contents will be greatly reduced. Then material will enter into second level cylinder. In this cylinder, hot air current is reverse with material transfer trend, material will be dry more evenly and thoroughly. In third cylinder, material water content is very low, drying process will go quickly.

Compare with traditional dryer, material will be dried over 5-6 times in ZJN Drying Equipment. And the covery area only 60% of single drum dryer.

We can match different hot air system for you, according to your Heat Source, no matter it is natural gas, bio-gas, coal, oil, bio-mass fuel or others. What’s more, if there is a boiler, the boiler flue gas can also be used as energy.

Advantage:

1. Simple structure, large production capacity.
2. Energy saving, little equipment running costs.
3. Drying equipment continuously working 24hours, continuously feeding wet material and continuously discharging finished product.
4. Fully automatic, easy and stable operation, low failure rate.
5. The size of dry sludge particles can be controlled as user’s requirements, to facilitate the next step.
6. The “horizontal installation” of the dryer is unique and easy to install.
7. Three cylinders drying equipment covers little area, save lots of plant investment.
8. The entire drying system is centralized control by ABB/Simens PLC, easy to operate. In the drying equipment, drying, crushing, sieving and conveying process are combined to operate. The whole process is simplified and easy to control automatically.
9. The solid particles in the air flow is highly dispersed in a suspended state. And the hot air and solid material conduct in two directions. So that the transfer surface area greatly increased. Since the inlet hot air speed is very high, gas-solid two-phase conduction speed is also very high. So the volume heat transfer coefficient is quite high. As the solid particles in the air flow is highly dispersed, making the material critical wet content greatly reduced.
10. High thermal efficiency, long drying time, large treatment capacity. Down-flow in the first stage cylinder, counter-flow in the second stage cylinder, down-flow in the third stage cylinder, S-type material transfer trend. Material mixed well with hot air. What’s more, the higher material moisture content is, the higher the temperature of hot air could be.
