Twin Roto Sifter 1350 Installation for High-Capacity Flour Processing
Overview
For high-capacity flour processing, screening equipment must operate at the same speed as the flour is processed without causing a production bottleneck.
For a large-scale flour processing application, Galaxy Sivtek installed the Twin Roto Sifter 1350, a twin-chamber centrifugal sifting system that will process high volumes of fine, low bulk density powders.
The goal was simple: provide more throughput of flour in a smaller design than with multiple discrete sifters and their extra connections, maintenance points and space.
The Challenge: Scaling Flour Screening Capacity
As production volumes increase, screening capacity must increase with them.
In high-throughput flour processing, adding several individual screening machines can help meet capacity requirements, but it can also make the process more complex. More machines mean more drives, connections, inspection points, cleaning requirements, and floor-space considerations.
The requirement was therefore not simply to install a larger flour sifter machine.
The processor needed a solution capable of handling a high material flow while keeping the screening stage compact, enclosed, and practical to maintain.
The Solution: Twin Roto Sifter 1350
For this reason, the Twin Roto Sifter 1350 from Galaxy Sivtek was recommended, a machine which combines two centrifugal screening chambers in one machine configuration.
Flour enters through a common inlet and is distributed between both screening chambers. Inside each chamber, rotating beaters move the flour towards the cylindrical mesh. The oversize particles are separated, and the fine material goes through the required openings in the screen.
Both chambers screen at the same time, while the material is split and passes through two screening sections.
The Twin Roto Sifter 1350, flour sieving machine is used for flour applications, with a capacity of up to 30 tons of product per hour, depending on the material characteristics, the mesh size, the feed condition and the machine configuration.
How the Installation Improved the Screening Process
Higher Capacity in a Compact Configuration
The twin-chamber arrangement provides two centrifugal screening actions within one integrated system.
This makes it suitable for processors that need to increase screening capacity without installing multiple completely separate machines.
Simplified Process Integration
Using one twin screening system can reduce the number of individual equipment interfaces required around the screening stage.
For high-capacity plants, this helps simplify installation, material routing, inspection, and routine maintenance.
Enclosed Flour Handling
Flour is a fine material, and during screening dust control is important.
Twin Roto Sifter is designed to keep the product contained during processing to help ensure cleaner material handling around the production area.
Easier Inspection and Maintenance
The machine is designed to provide access to internal screening components for routine inspection, cleaning, and mesh changes.
If processors are producing large quantities of products, it will be easier for them to make access because it will eliminate unnecessary complexity in maintaining the equipment and make it easier for the processors.
Low-Vibration Operation
Separation takes place through centrifugal action inside the screening chambers rather than through vibration of the complete machine body.
This enables the equipment to run with little external vibration that makes the integration with existing processing lines easier.
The Operational Impact
The installation provided a more practical approach to high-capacity flour screening by combining two screening chambers within one system.
Instead of increasing capacity by multiplying individual screening units, the Twin Roto Sifter 1350 allows large material volumes to be distributed across two centrifugal chambers operating simultaneously.
The result is a screening arrangement that supports:
- high-volume flour processing,
- reduced equipment complexity,
- compact installation,
- enclosed material handling,
- and easier access for routine maintenance.
For processors planning capacity expansion, this type of configuration can help prevent the screening stage from becoming a limitation as production volumes increase.
Conclusion
High-capacity flour processing requires more than increasing upstream production. The screening stage needs to be able to screen the same quantity of material without complicating the process needlessly.
The Twin Roto Sifter 1350 is a practical solution as it merges two centrifugal screening chambers into one compact and easy-to-manage screening system, allowing the processor to obtain higher screening capacity with a smaller footprint.
For flour processors evaluating a capacity expansion or upgrading an existing screening line, Galaxy Sivtek can assess the material, required throughput, mesh specification, and process conditions to recommend the most suitable screening configuration.
