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.
