Compact, Modular Bulk Storage with Controlled Discharge for Seeds, Grains and Powders
Engineered for the Future | Since 2080
The ADDAMS Rectangular Silo – Flow Floor Type is a high-efficiency, space-saving storage solution for bulk materials, including grains, seeds, pulses, and powders. Unlike traditional round silos, this rectangular configuration is designed for modular installation, optimizing floor space in processing plants, packaging lines, and industrial warehouses.
Equipped with a flow floor (a mechanical or pneumatic moving bottom), it enables uniform, first-in-first-out (FIFO) discharge, eliminating dead zones and product bridging—critical for fragile, sticky, or flow-resistant materials.
Rectangular Silo – Flow Floor Type Overview
Optimized Space and Intelligent Discharge
The Rectangular Flow Floor series is the ultimate solution for plants with height or floor space restrictions. By utilizing a rectangular footprint, these silos can be placed wall-to-wall, while the specialized flow floor technology ensures that even the most “difficult” materials are discharged consistently without manual intervention.
Reliable Performance for Complex Materials
This system is particularly effective for products that tend to compact or bridge in standard hoppers. The active discharge floor breaks up material clusters, ensuring a steady feed to your conveyors, scales, or packaging machines, regardless of the product’s internal friction.
Operating Principle of the Flow Floor Silo
Active Bottom Discharge Technology
Instead of relying solely on gravity, the Flow Floor Silo uses a mechanical or pneumatic active floor. As the discharge gate opens, the floor system (vibrating plates or moving components) creates a uniform downward movement across the entire cross-section of the silo. This prevents “ratholing” where only the center of the material moves, ensuring a true FIFO (First-In, First-Out) process.
Integrated Flow Control
The intensity of the floor movement can be adjusted via the PLC to match the required flow rate. This allows for precise control over how much material is released, making it an ideal buffer station for dosing and blending lines where consistency is paramount.

Frequently Asked Questions – Rectangular Silos
What is the main benefit of a “Flow Floor” compared to a standard hopper?
A standard hopper relies on gravity, which can lead to “bridging” where the material gets stuck. A Flow Floor is an active system that mechanically ensures the material moves, which is vital for powders or sticky products.
Can I install these silos side-by-side without gaps?
Yes. One of the biggest advantages of the rectangular design is that they can be placed flush against each other or against walls, utilizing nearly 100% of your available floor space.
Is the flow floor noisy?
Our modern electric and pneumatic drives are designed for industrial environments and operate at controlled decibel levels. For sensitive areas, we can provide additional acoustic damping.
How do I clean the inside of the silo?
The silo is equipped with multiple access points, including side inspection doors and top manholes, allowing for thorough cleaning and inspection between different product batches.
Can the discharge rate be adjusted?
Absolutely. By controlling the speed or frequency of the flow floor mechanism via the PLC, you can precisely tune the discharge rate to match your packaging or processing speed.
Are these silos shipped pre-assembled?
Depending on the size, we can ship them as complete units or in modular sections that are bolted together on-site, making it easy to bring them into existing buildings through standard industrial doors.
