NNP sieve vibratory sieving unit

Applications & Use Cases

• Separating fine powders from coarser particles in baking and confectionery.
• Grading spices and seasonings by particle size for consistent product quality.
• Removing foreign objects or agglomerates from dry ingredients before mixing.
• Sifting flours and starches to improve aeration and prevent lumps.
• Processing dairy powders to ensure uniform texture and dissolve rates.

Typical Specifications

Typical capacity

For this class of equipment, throughput can range from 100 kg/hr to several tonnes/hr, depending on mesh size and product density.

Power supply

Commonly found on units of this type, a 3-phase electrical supply (e.g., 400V, 50Hz) is typically required, though smaller units may be single-phase.

Sieve diameter

Typically, sieve diameters for industrial vibratory units range from 450mm to 1200mm, influencing screening area.

Mesh sizes

A wide range of interchangeable mesh sizes are usually available, from very fine (e.g., 50 microns) to coarse (e.g., 10mm), to suit various separation needs.

Construction material

Units for food processing are commonly constructed from 304 or 316 grade stainless steel for hygiene and corrosion resistance.

Vibration mechanism

Typically, these units utilise an unbalanced motor to create a multi-plane vibratory action, aiding material flow and separation.
