Radpak Linear Weigher Bagging Line

• Packaging of free-flowing granular products such as nuts, seeds, pulses, and confectionery.
• Bagging of snack foods, cereals, and dried fruits.
• Filling of non-food items like small hardware components or pet food.
• Automated packaging in environments requiring precise weight control and consistent bag presentation.

Typical throughput

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

Weighing accuracy

Linear weighers are designed for high accuracy, commonly achieving tolerances of +/- 0.5g to 2g for target weights, depending on product characteristics.

Bagging machine type

The Sandiacre TG320LF suggests a vertical form fill and seal (VFFS) machine, commonly used for producing pillow bags, gusseted bags, or block bottom bags.

Power supply

Units of this type typically require a 3-phase electrical supply, commonly 400V, 50Hz, with an associated compressed air supply for pneumatic components.

Construction materials

Given the 'dimple pan finish' and 'stainless steel' description, food-grade stainless steel (e.g., 304 or 316) is typically used for product contact parts to ensure hygiene.

Footprint

A complete line with an infeed elevator, gantry, weigher, and bagging machine will require a significant operational footprint, typically several metres in length and width.

Control system

Modern units feature touch screen controls, commonly offering recipe management, production data logging, and diagnostic functions.

• What types of products are suitable for a linear weigher?

  Linear weighers are best suited for free-flowing, granular, or small piece products that can be accurately dispensed by vibration and gravity.

• What are the advantages of a linear weigher over a multihead weigher?

• What maintenance is typically required for this type of equipment?

• Is specialist training required to operate this bagging line?

Filling machines remain sought-after on the secondhand market due to their durability and long operational lifespan. Buyers typically value models from established manufacturers known for robust construction. When purchasing used units, inspectors should verify seal integrity, calibration accuracy, and maintenance history, as these directly affect product consistency and line efficiency. Common strengths include straightforward mechanical design facilitating repairs and adaptability to different container sizes. Reliability and minimal downtime are frequently cited priorities among processors seeking cost-effective production solutions.
