Checkweighers and Conveyors

• Ensuring product weight compliance in packaged food lines.
• Minimising product giveaway by accurately identifying underweight items.
• Detecting overfilled packages to prevent material waste and regulatory issues.
• Integrating into existing conveyor systems for automated quality control.
• Sorting products into weight categories for specific packaging or distribution.

Typical throughput

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

Weighing accuracy

Units of this type typically offer accuracy down to +/- 0.1g to +/- 1g, suitable for various packaged goods.

Product weight range

Commonly, these checkweighers handle products from a few grams up to 10-20 kg, though specific models vary.

Conveyor belt width

Belt widths are typically between 150mm and 400mm, accommodating a range of product dimensions.

Power supply

Units commonly require a standard industrial single-phase or three-phase supply, typically 230V or 400V, 50Hz.

Construction material

Frames and contact parts are commonly constructed from stainless steel for hygiene and durability in food environments.

Environmental rating

Many units are rated to IP54 or IP65, indicating suitability for washdown environments.

• What types of products can these checkweighers handle?

  These units are typically suitable for a wide range of packaged food products, including pouches, cartons, trays, and rigid containers. The specific product dimensions and weights should be confirmed with the seller.

• Are these units suitable for integration into an existing production line?

• What level of accuracy can be expected from a used checkweigher?

• Do these units come with rejection systems?

• What maintenance is typically required for checkweighers?

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.
