Paddy Rice Grain Dryer Tower Drying Equipment for Rice Milling Plant Line

Freshly harvested paddy usually carries between 18 and 28 percent moisture, and at that level it cannot be stored or milled economically. If the grain is dried too fast it cracks and the milling yield collapses, and if it is stored too wet it heats, moulds and loses value. The Paddy Rice Grain Dryer Tower solves both problems by removing moisture gently and evenly to a safe, mill ready level.

The dryer is a continuous flow tower in which grain descends by gravity through alternating rows of hot air and tempering sections. Heated air is drawn across the grain column by centrifugal fans, and the direction of airflow and the grain discharge speed are adjusted so that every kernel loses moisture at the same controlled rate. A tempering zone at the base lets internal moisture migrate to the surface before it is removed, which is the key to crack free drying.

Available with rice husk, coal, diesel or biomass hot air furnaces, the tower dries from 25 percent moisture down to 14 percent in a single pass or in multiple gentle passes. Automatic moisture monitoring lets the operator set the target and walk away, while the low grain drop height protects the delicate kernel structure.

• Even Moisture Removal: Alternating airflow sections and a tempering zone equalise moisture inside each kernel, achieving crack free drying and a higher head rice yield.
• Multiple Heat Sources: The tower can be fired by rice husk, biomass, coal, diesel or gas, letting each mill use its cheapest local fuel.
• Large Capacity: Standard towers handle 10 to 100 tons of wet paddy per hour, matching the throughput of medium and large rice milling plants.
• Gentle Handling: The grain column and discharge mechanism use a low drop height, so mechanical stress and broken grain are kept to a minimum.
• Automatic Moisture Control: An online moisture sensor linked to the PLC adjusts discharge speed and air temperature to hold the final moisture exactly on target.
• Robust Construction: The galvanised steel tower and wear resistant internals resist the dusty, humid environment of a working rice mill for many seasons.

The Paddy Rice Grain Dryer Tower is used in rice mills, grain depots, central procurement stations and seed production bases. It dries paddy, wheat, corn and other cereals, and it can be combined with a cleaning and destoning section to form a complete post harvest handling line.

The dryer tower is shipped in bolted sections with fans, burners and control cabinets packed separately and protected against moisture. All mating faces are sealed and the electrics are wrapped for sea transport. Installation drawings, an operating manual and commissioning support are supplied, and the tower carries a twelve month warranty against manufacturing defects.
