Graseby Best Checkweigher

• Ensuring packaged food products meet specified weight tolerances.
• Reducing product giveaway and ensuring compliance with weight legislation.
• Identifying under- or over-weight products for rework or rejection.
• Integrating into automated production lines for continuous quality control.
• Monitoring production line efficiency and identifying process issues.

Typical throughput

For this class of equipment, throughput can typically range from 60 to 200 items per minute, depending on product size and stability.

Weighing range

Units of this type commonly handle products from a few grams up to several kilograms. This specific unit is noted for 100g - 500g.

Accuracy

Checkweighers are typically designed for high accuracy, often to +/- 0.5g or better for lighter products, depending on speed and product characteristics.

Construction material

Units for food processing are almost exclusively constructed from stainless steel for hygiene and durability, as noted for this unit.

Power supply

Commonly 3-phase electrical supply (e.g., 400V, 50Hz) and often requires a compressed air supply for reject mechanisms.

Reject mechanism

Pneumatic blow reject systems are common for lightweight products, offering fast and efficient removal of non-conforming items.

Footprint

Overall length for a unit of this type is commonly around 1.5m to 2m, with the weigh platform being a key determinant of product size handling.

• What maintenance is typically required for a checkweigher?

  Routine maintenance typically involves cleaning, calibration checks, and inspection of belts, sensors, and pneumatic components. Regular calibration is crucial for accuracy.

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

• What kind of products is this unit suitable for?

• What are the typical environmental requirements for a checkweigher?

• Is calibration necessary for a used checkweigher?

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.
