Multifunctional Cleaning and Grading for Grains, Pulses, and Oilseeds
Engineered for the Future | Since 2080
The ADDAMS Rotary Drum Seed Cleaner Machine is designed for multifunctional purposes, serving as a high-capacity pre-cleaner, air screen cleaner, and precise grader. Utilizing a rotating cylindrical drum with exchangeable perforated screens, this machine efficiently removes oversized, undersized, and foreign materials before final processing.
This ensures improved downstream performance and reduced wear on subsequent equipment. After initial pre-cleaning and safe storage, the machine allows for efficient Air Screen Cleaning and detailed Grading of a wide range of grains, pulses, legumes, and oilseeds simply by changing the perforated screens.
Rotary Drum Seed Cleaner Overview
High-Capacity Versatility in Grain Cleaning
The ADDAMS Rotary Drum series is the multi-tool of the seed processing world. Whether you need to process massive amounts of raw intake as a pre-cleaner or require the delicate precision of a final grader, this machine adapts to your workflow. Its rotating action ensures that every single seed comes into contact with the screen surface, providing superior separation compared to traditional flat-screen systems.
Reliable Performance for Grading and Sorting
By maintaining a constant rotational speed and utilizing gravity, the machine classifies seeds based on their physical dimensions with extreme accuracy. This makes it an essential component for facilities producing certified seeds or high-value export-grade commodities where size uniformity is a critical quality metric.
Operating Principle of the Rotary Drum Cleaner
Centrifugal Separation and Gravity Flow
Material enters the rotating drum and passes through a sequence of cylindrical screens with increasing precision. As the drum rotates, oversized impurities are separated in the early stage, while undersized particles and dust fall through dedicated outlets. The cleaned product exits through the central discharge, ready for secondary processing stages.
Multi-Stage Processing Logic
The machine can be equipped with multiple screen sections, each with different perforation sizes. This allows the operator to perform scalping (removing large trash), sifting (removing small debris), and grading (sorting into different sizes) all within a single pass through the machine.

Frequently Asked Questions – Rotary Drum Cleaner
How long does it take to change the screens for a different crop?
Our modular drum design allows for relatively quick screen changes. Depending on the model, a full set of screens can be swapped out in 30 to 60 minutes, allowing you to switch crops on the same day.
Can this machine replace a flat-bed air screen cleaner?
While it can perform air screen cleaning, its primary strength is high-capacity pre-cleaning and precise grading. For many plants, it works perfectly as a primary cleaner before the product moves to further processing.
Does the rotating drum damage the seeds?
No. The drum rotates at a controlled, low speed. The tumbling action is very gentle, as the seeds slide along the smooth perforated surface rather than being vibrated aggressively.
Is it effective at removing dust and light chaff?
Yes, when connected to an external aspiration system. The machine features ports that allow air to be drawn through the material as it tumbles, pulling away light impurities while the screens handle size-based separation.
Can it handle wet or high-moisture grain?
While it is primarily designed for dry materials, the rotary action is more effective than flat screens at handling slightly damp material that might otherwise clog a traditional vibrating screen.
What is the maintenance requirement for the drum?
Maintenance is minimal. Periodic lubrication of the main bearings and checking the screen wear are the primary tasks. Because it has fewer moving parts than a vibrating cleaner, it offers long-term reliability.
