Vemag - Checkweigher

• 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 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.

• What is the typical footprint of a checkweigher?

  The footprint varies significantly but typically ranges from 1 to 2.5 metres in length and 0.5 to 1 metre in width, excluding any infeed or outfeed conveyors.

• Can this equipment be integrated into an existing production line?

• What kind of maintenance does a used checkweigher require?

• Are spare parts readily available for unknown manufacturer models?

• What certifications should I look for?

Checkweighers are valued in food processing for reliable weight verification and compliance support. Buyers typically prioritise accuracy, speed, and ease of integration with existing production lines. When purchasing used units, inspecting calibration history, mechanical condition, and software functionality proves important. Industry sentiment favours models offering consistent performance, straightforward maintenance, and robust build quality. Durable construction and proven track records across multiple production environments remain key considerations for buyers assessing secondhand equipment.
