Vemag - Checkweigher

Applications & Use Cases

• Ensuring individual food products meet specified weight targets before packaging.
• Detecting and rejecting under- or overweight packs to comply with legal metrology regulations.
• Reducing product giveaway and optimising fill levels in automated production lines.
• Verifying the presence of all components in multi-pack items.
• Sorting products into different weight categories for further processing or packaging.

Typical Specifications

Typical throughput

For this class of equipment, throughput commonly ranges from 60 to 300 items per minute, depending on product size and weight.

Weighing accuracy

Units of this type typically offer accuracy within +/- 0.5g to +/- 2g, crucial for compliance and waste reduction.

Product weight range

Commonly, checkweighers can handle products from a few grams up to 10-15 kg, though specific models vary.

Conveyor belt width

Belt widths are typically between 150mm and 400mm to accommodate various product dimensions.

Power supply

Most units operate on a standard industrial single-phase or three-phase supply, commonly 230V or 400V AC, 50Hz.

Construction material

For food processing, units are typically constructed from stainless steel (e.g., 304 or 316 grade) for hygiene and durability.

Rejection system

Common rejection systems include air blast, pushers, or drop-down conveyors, selected based on product fragility and speed.
