El Flour Powder Tank Semi-Trailer is widely used for transporting bulk flour and other dry food powders between mills, processing facilities, warehouses, distribution centers, and food production plants. It supports efficient delivery for businesses that handle large quantities of powdered ingredients.
The sealed tank system helps maintain a clean and controlled transportation environment, reducing exposure to rain, dust, and other external elements. At the destination, the pneumatic unloading system allows the powder to be transferred directly into storage silos or processing equipment, helping reduce manual handling and improve unloading efficiency.
From flour production and food processing to bulk ingredient distribution, this semi-trailer provides a practical transportation solution for maintaining a consistent and efficient supply of dry powder materials.

High quality axle with strong load capacity, stable performance and long service life. Optional FUWA / BPW brand.

High-strength low alloy steel Q345B, good toughness and wear resistance.

Equipped with heavy-duty tubeless tires. Excellent heat dissipation reduces tire burst risk during continuous transportation. Strong wear resistance and grip, suitable for various road conditions.

Powerful diesel engine, stable output for powder discharging.

Professional air compressor matched for powder conveying. It supplies stable compressed air to fluidize dry powder inside tank, realizing fast discharging with low material residue rate ≤0.3%.

Equipped with dual safety valves for double protection. It automatically releases excess pressure to keep the tank safe during powder discharging.
