Vibratory Sifter for Screening Flour

Vibratory Sifter for Screening Flour employs a multi-layer sieve configuration, continuously separating feed into 2 to 6 different particle size ranges according to preset particle size specifications. During the screening process, it removes contaminants and other unwanted particles from wheat flour. The sieve mesh sizes cover a wide range from 20 to 500 mesh, allowing users to flexibly select the configuration based on the target product particle size—higher mesh numbers correspond to smaller sieve apertures, effectively removing minute impurities such as foreign objects, agglomerates, and oversized particles, resulting in a very fine and uniform product. It can also grade flour by particle size as needed.

Why Vibratory Sifter Is Used for Flour Screening？

Flour is a light powder material with small particle size and good flowability. However, it can also absorb moisture easily during storage, especially in humid environments. Once slight agglomeration appears, flour feeding and packaging may become unstable.Using a vibratory sifter can provide the following practical benefits:

Improve Flour Uniformity The screen separates oversized particles and helps keep flour particle size more consistent before mixing or packaging.

Remove Lumps Moisture-related agglomerates can be removed before entering the next production stage.

Reduce Foreign Matter Risk Fibers, paper fragments, or other visible contaminants can be intercepted during screening.

Improve Packaging Stability Uniform flour flows more smoothly into automatic packing machines.

Reduce Manual Labor Compared with hand sieving, mechanical screening supports continuous production.

How does the vibratory sifter for screening flour work?

The working principle of the vibrating sifter for screening flour is to vibrate the screen frame through the excitation force generated by the vibration motor, thereby screening the raw material particles on the screen.

The specific process is: after the raw materials are evenly distributed in the screen frame, they are affected by the vibration force. The large particles move to the front edge under the action of the vibration force and are gradually discharged from the equipment outlet, while the small particles pass through the screen and are discharged from below.

The material outlet is discharged, thus realizing the separation of materials with different particle sizes.

Installation Feedback

After installation and trial operation, customers reported several improvements in daily production performance: flour feeding was smoother, packaging weight stability was improved, clumping in finished product bags was reduced, dust around the sieving area was reduced, and cleaning time was shorter than with the previous manual sieving equipment. Furthermore, the equipment can be integrated into the existing production line without requiring major layout modifications.
