Flour Sifter Machine
Industrial Flour Sifter Machine for continuous screening of wheat flour, corn flour, rice flour, cassava flour, starch and other dry powders. The circular vibro sifter removes lumps, oversized particles and unwanted impurities while providing consistent screening performance.

Flour Sifter Machine for Industrial Powder Screening
Flour quality can be affected by lumps, oversized particles, impurities and inconsistent particle size. For continuous production, manual sieving can also require significant labor and may become a bottleneck.
Our Flour Sifter Machine uses controlled vibration to move flour across the screen surface and separate particles according to the selected mesh size.
The machine can be configured with different screen meshes, screening layers, materials and discharge arrangements according to your production requirements.
It can be used as a standalone flour screening machine or integrated with conveyors, feeders, hoppers and packing systems.
Common Flour Screening Problems
Before choosing a flour sifting machine, many processors face similar production problems.
Flour Lumps and Agglomerates
Flour can form lumps during storage, transportation or processing. These agglomerates may affect feeding, mixing and the consistency of the final product.
A suitable flour sifter separates oversized lumps from the finer flour particles during continuous screening.
Manual Sieving Is Too Slow
Manual sieving may be practical for small batches, but it becomes inefficient when production volume increases.
Operators need to repeatedly feed, shake and clean the sieve, increasing labor requirements and making continuous production difficult.
A vibrating flour sifter automates the screening process and can operate continuously.
Inconsistent Screening Results
Manual screening depends on operator technique, screening time and material handling.
With a defined screen mesh and controlled vibration, the Flour Vibro Sifter provides a more consistent screening process.
Screen Mesh Blocking
Fine flour particles can accumulate on the screen surface and reduce screening efficiency.
For fine powders or applications with higher mesh requirements, an optional ultrasonic screening system can be considered to help reduce mesh blockage.
Oversized Particles and Impurities
Flour may contain oversized particles, agglomerated material or unwanted particles that need to be removed before further processing.
The screening machine separates the material according to the selected mesh size and discharges oversized material separately.
Production Bottlenecks
As production increases, manual or undersized screening equipment can become a bottleneck.
An industrial flour sifter can be connected with feeding and conveying equipment to create a continuous screening process.

What Is a Flour Sifter Machine?
A Flour Sifter Machine is an industrial screening machine designed to separate flour according to particle size and remove unwanted oversized particles or impurities.
Our machine uses a circular vibrating screening principle. A vibration motor generates controlled vibration, causing the flour to move across the screen surface.
Fine particles pass through the selected screen mesh, while oversized particles remain on the screen and are discharged through a separate outlet.
The machine can be configured with one or multiple screening layers depending on the required separation.
How Does a Flour Vibro Sifter Work?
The Flour Vibro Sifter uses vibration to continuously move flour across the screening surface.
The basic process is:
Feeding → Vibrating Screening → Fine Flour Passing Through Mesh → Oversize Discharge
When flour enters the machine, the vibration causes the material to spread across the screen.
Particles smaller than the selected mesh openings pass through the screen, while larger particles remain on the screen and move toward the discharge outlet.
For multi-layer configurations, different screen meshes can be used to classify the material into multiple particle-size fractions.

Key Features of Our Flour Sifter Machine
Stainless Steel Construction
304 or 316L stainless steel can be selected for material-contacting parts according to the application requirements.
The smooth internal surface can help reduce material residue and make cleaning easier.
Efficient Vibrating Screening
The circular vibration helps distribute flour across the screen surface and provides continuous contact between the material and screen mesh.
Customized Screen Mesh
The screen mesh can be selected according to:
- Flour type
- Particle size
- Required screening fineness
- Production capacity
- Screening stages
Single or Multiple Screening Layers
The machine can be configured with different numbers of screening layers.
A single-layer machine is suitable for basic impurity removal or simple separation.
Multi-layer configurations can be used when several particle-size fractions need to be separated.
Adjustable Vibration
The vibration intensity can be adjusted according to material characteristics and screening requirements.
This helps optimize material movement and screening performance.
Easy Screen Replacement
The screening structure is designed for convenient inspection, cleaning and screen replacement.
Optional Ultrasonic Screening
For fine powder applications where mesh blockage is a concern, an ultrasonic screening system can be added.
The ultrasonic system can help improve the screening of fine powders and reduce material accumulation on the screen.
Customized Feed and Discharge
Feed inlets and discharge outlets can be customized according to the customer’s production line.
Different outlet positions and configurations can be designed according to the installation requirements.

Actual screening capacity depends on material characteristics, moisture content, bulk density, particle size, screen mesh, number of layers, feed rate and required screening efficiency.
For this reason, the machine model should be selected according to the actual flour and production requirements rather than capacity alone.
What Flour Can Be Screened?
The Flour Sifter Machine can be used for different types of dry flour and powder materials.
Common applications include:
- Wheat flour
- Corn flour
- Rice flour
- Cassava flour
- Potato starch
- Corn starch
- Tapioca starch
- Soy flour
- Sugar powder
- Salt
- Cocoa powder
- Spice powder
- Other dry food powders
Different materials have different flowability, moisture content and particle-size distributions. The screen mesh and machine configuration should therefore be selected according to the specific material.
Flour Sifter Applications
Flour Mills
In flour mills, the machine can be used for screening flour after milling or before further processing.
It helps separate oversized particles and improve particle-size consistency.
Bakeries
For commercial bakeries, screening flour before mixing can help remove lumps and unwanted oversized particles.
Food Processing Plants
The flour sifter can be integrated into automated powder handling and food processing lines.
Grain Processing
Different grain-based powders can be screened according to their particle-size requirements.
Powder Processing Lines
The machine can be connected with conveyors, feeders, hoppers, mixers and packing machines.
Single-Layer vs Multi-Layer Flour Sifter
The number of screening layers depends on the required separation process.
| Configuration | Typical Application |
|---|---|
| Single Layer | Basic flour screening and impurity removal |
| Two Layers | Two-stage particle separation |
| Three Layers | Multiple particle-size classification |
| Multi-Layer | More complex classification requirements |
If your main purpose is removing lumps and oversized particles, a single-layer configuration may be sufficient.
If several particle-size fractions need to be separated, a multi-layer configuration can be considered.

How to Choose a Flour Sifter Machine
Choosing the right flour sifter requires more than simply selecting a machine diameter.
1. Material Type
Tell us what material you need to screen, such as wheat flour, corn flour, rice flour, cassava flour or starch.
2. Required Capacity
Provide the required production capacity in kg/h or t/h.
Capacity depends on material characteristics, mesh size, screen area and required screening efficiency.
3. Required Mesh Size
The screen mesh should be selected according to the particle size that needs to pass through the screen.
