Precision Cleaning and Grading for Optimal Product Quality and Efficiency
Engineered for the Future | Since 2080
The ADDAMS Optimum Fine Cleaner and Grader series represents the pinnacle of seed processing technology. Designed to separate light impurities, small seeds, and damaged particles from dry products, these machines ensure your harvest reaches its full market potential. By combining advanced flat reciprocating screens with powerful air aspiration systems, the Optimum series delivers industrial-grade purity for grains, pulses, oilseeds, and specialized crops.
Gentle product handling is at the core of our design philosophy. ADDAMS equipment is engineered to respect the integrity of your seeds, maintaining high germination rates and superior visual quality while maximizing operational throughput.
Optimum Fine Cleaner and Grader Overview
Superior Purity and Sorting Precision
The Optimum series is divided into two primary functions: fine cleaning and high-precision grading. The Fine Cleaner focuses on removing dust, husks, and undersized seeds, while the Grader classifies materials into uniform size fractions. This dual-capability ensures that only the highest quality product continues through your production line.
High-Efficiency Air Screen Technology
Using a combination of balanced reciprocating screens and multi-stage air systems, these machines are estimated to remove approximately 85% of impurities and 75% of small or immature seeds. This transition significantly elevates the grade of the final product, making it ready for high-value export or certified seed use.
Key Features of the OPTIMUM Series
-
Full-width Vibratory Feeder: Features stepless adjustment of the feed rate via an inverter, ensuring a uniform, self-cleaning flow across the entire sieve width.
-
Pre- and After-Suction Systems: Built as independent units to ensure precise air cleaning, removing light particles before the material even reaches the sieves.
-
Balanced Eccentric System: Fitted with counterweights and heavy-duty bearings to ensure steady running with minimum stress on building structures.
-
Birch Plywood or Metal Screenshoes: Moisture and insect-resistant materials that reduce resonance, providing a better working environment and long-term durability.
-
Food-Grade Ball Box: Utilizes rubber balls for continuous, efficient self-cleaning of the sieves, ensuring zero downtime for screen maintenance.
-
Air Lifting Channel: Eliminates light seeds in a variable expansion chamber, guiding husks and dust away from the main product stream.
-
Flexible Product Flow: Allows for multiple different sorting fractions by easily changing the sieves and the position of the outlet trays.

Frequently Asked Questions – Fine Cleaners
What is the difference between a pre-cleaner and a fine cleaner?
A pre-cleaner is used for high-capacity removal of large trash during intake. A fine cleaner, like the Optimum series, is used for precision sorting, removing small seeds, and fine dust to achieve final product purity.
Can the machine separate damaged seeds from healthy ones?
Yes. The Grader function utilizes reciprocating screens and air lifting channels to separate seeds that are broken, immature, or damaged based on their weight and size.
How often do the screens need to be cleaned?
The machines feature an integrated ball box system that uses rubber balls to clean the sieves while the machine is running. This self-cleaning mechanism prevents clogging and maintains constant performance.
Is the air system adjustable for different crops?
Absolutely. Both the pre-suction and after-suction systems are independent and can be adjusted to handle different weights of product, from light flower seeds to heavy maize.
Why is birch plywood used for the screen shoes?
Birch plywood is highly resistant to moisture and insects. More importantly, it absorbs vibrations better than metal, which leads to a quieter working environment and less stress on the machine’s frame.
What is the purpose of the air lifting sieve screen?
This specialized screen turns the seed so its biggest surface faces the air flow. This maximizes the efficiency of the air separation, ensuring even the smallest light particles are removed.
