Dosing and Blending Line

High-Performance Blending Line for homogeneous Seed Blends

For this project, a modern dosing and blending plant was integrated into an existing building. At the heart of the system is the 15 m³ double-shaft horizontal blender Type RDM 15 – our largest high-performance blender for fast, gentle and homogeneous production of seed blends.

The plant was precisely adapted to the customer’s process requirements, the existing building situation and downstream packaging. From intake and weighing of the individual components to conveying, blending and transfer to packaging, the result is an integrated plant solution for high production capacities.

Insights

The individual components are fed via a box intake. The components are emptied from boxes into the intake hopper and conveyed to the blender by discharge dosing belt conveyor and a slow speed bucket elevator designed for gentle and residue free product handling. Load cells below the intake hopper enable controlled dosing of the components according to the specified blending recipe.

The product is then transferred into the 15 m³ horizontal blender. The RDM 15 is designed for large batches and short blending times. Two horizontally arranged, counter-rotating blending shafts ensure fast and uniform blending of a wide range of seed types.

A key advantage of the RDM blenders is the combination of large usable volume and flexible batch size. Blending can already be carried out from a filling level of approx. 25 %, allowing not only very large batches but also smaller quantities to be processed.

After the blending process, the two-part bottom flap opens across the entire area of the blending chamber. The finished mixture is discharged into the buffer hopper within seconds. This direct discharge not only saves time, but above all helps prevent renewed segregation of the different components.

From the buffer hopper, the finished mixture is transported to packaging. For full quality control an automatic sampler enables representative sampling from the product flow after the blending process.

Highlights

A key requirement was the integration of the complete plant into the existing building. Machine positioning, conveying routes, platforms, maintenance access, aspiration system and connection to packaging all had to be precisely coordinated with the existing structural conditions.

The horizontal blender Type RDM 15 forms the technical centerpiece. With its large volume and robust design, it is built for highest production capacities and demanding industrial blending tasks.

Dedusting was also planned as part of the overall concept. The aspiration and exhaust air dedusting system captures relevant extraction points at intake, conveyors, blender and packaging, supporting clean and reliable plant operation.

The control and automation system connects all individual components into one continuous process. Thanks to the clear visualization, the individual plant areas can be operated logically and adapted to the respective recipes and production sequences.

With this plant, a powerful yet flexible solution was implemented, combining high capacity, controlled dosing, homogeneous blending quality and integration into existing production structures.
