Vibratory Sieve

Applications & Use Cases

• Separating fine powders from coarser particles in baking and confectionery.
• Grading ingredients like spices, grains, or nuts by size for quality control.
• Removing foreign objects or lumps from bulk dry goods before further processing.
• Dewatering certain food products after washing or blanching.
• Recovering usable product from waste streams in food production.

Typical Specifications

Typical capacity

Varies significantly, but 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 are 400V, 3-phase, 50Hz, with power consumption typically between 0.5 kW and 2.2 kW.

Screen diameter/area

Typically ranges from 600mm to 1500mm in diameter for single-deck units, influencing the effective screening area.

Mesh sizes available

Units are typically supplied with interchangeable screens, offering mesh sizes from as fine as 50 microns up to several millimetres.

Construction material

For food processing, contact parts are typically made from 304 or 316 grade stainless steel to meet hygiene standards.

Footprint

A typical vibratory sieve requires a floor space of approximately 1m x 1m to 2m x 2m, plus access for maintenance.

Vibration mechanism

Units commonly employ an unbalanced weight motor to generate multi-plane vibration for efficient particle separation.
