Cotswold Mechanical Ltd - LINEAR WEIGHER 4 LANE

• Accurate portioning of free-flowing and semi-free-flowing granular products.
• Dispensing ingredients in food processing, such as confectionery, snacks, and dry pet food.
• Packaging lines requiring precise weight control for products like nuts, seeds, and small pasta.
• Automated assembly processes where components need to be weighed and batched accurately.

Typical throughput

For a 4-lane linear weigher of this class, throughput can typically range from 20 to 60 weighments per minute, depending on product characteristics and target weight.

Weighing range

Units of this type commonly handle target weights from a few grams up to several kilograms per weighment, adjustable via change parts and settings.

Accuracy

Typically achieves accuracy within +/- 0.5% to 1.5% of the target weight, influenced by product consistency and speed.

Power supply

Commonly requires a 230V, single-phase, 50Hz electrical supply, with some units potentially needing a three-phase connection or compressed air.

Material contact parts

Typically constructed from food-grade stainless steel (e.g., 304 or 316) for hygiene and durability, especially in food processing applications.

Footprint

A 4-lane linear weigher with gantry typically requires a floor space of approximately 1.5m x 1.5m, plus space for infeed and outfeed conveyors.

• What types of products are best suited for a linear weigher?

  Linear weighers are ideal for free-flowing and semi-free-flowing granular products, small pieces, and items that can be accurately vibrated or conveyed into weigh buckets. They are less suitable for sticky or very irregularly shaped items.

• How does a linear weigher differ from a multihead weigher?

• What maintenance is typically required for a used linear weigher?

• Can this unit be integrated into an existing packaging line?

• What are 'change parts' and why are they important?

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.
