SIFTING
Material separation technology tailored to fit your process

What is sifting?
Sifting involves separating, classifying, or refining powders and granules by passing them through a defined mesh or screen. This not only removes unwanted foreign particles and oversized materials but also ensures a uniform particle size distribution, which is critical for downstream processing. In industries where hygiene and regulatory compliance are essential, such as food and pharmaceuticals, sifting also helps guarantee purity and adherence to strict quality standards.
Typical applications
Sifting equipment is widely used across diverse production environments.
In food manufacturing, sifters help screen flour, starch, sugar, cocoa, spices, and other powdered ingredients to deliver consistent textures and eliminate contaminants.
In the pharmaceutical industry, sifting ensures the uniformity of excipients and active ingredients, preventing agglomerates that could affect dosage accuracy or tablet compression.
Comparison between flat deck sifters and centrifugal sifters
Flat deck sifters and centrifugal sifters are the technology categories used to perform product sifting effective. Flat deck sifters, also known as vibrating sifters, are ideal for precise particle size classification and gentle handling of fragile products. They are best suited for applications where accurate separation across multiple fractions is required. Centrifugal sifters, on the other hand, excel in high-throughput operations where bulk powders must be quickly screened or safety-checked.
Feature | Flat deck sifters | Centrifugal sifters |
---|---|---|
Best for | Applications with multi-step accurate separation | High-throughput operations of bulk powders |
Efficiency | Higher residency time | Lower residency time |
Speed | Slower processing | Faster processing |
Level | Several levels of separation | Single level of separation |
Dust generation | Generates more dust airborne particles due to movement | Generates less dust. Enclosed operation, less air displacement. |
Capacity | Lower capacity rates per screen area | Higher capacity rates per screen area |
Vibration level | Vibrate / tumble | Low vibration / static |
Noise | Noisy | Low noise levels |
