Linear weigher is more efficient than conventional circular systems
An automated linear weighing machine is introduced that can weigh products with brittle shells at higher speeds and with fewer breakages compared to conventional circular systems
In Use – The first installation of this system is in place in a confectionary business in France.

Details

An automated linear multi-head weighing machine has been developed that can weigh products with brittle shells that are prone to breaking at higher speeds and with fewer breakages compared to conventional circular systems.

Products are fed into the weigher through a vibrating feeder. Portions of confectionary are then weighted using around fourteen hoppers. A computer selects the correct combination of hoppers that come closest to the target weight and the hoppers are then discharged into the packaging machine. Compared to a circular weigher, the linear weigher has a reduced dropping distance as products pass through the machine. Shock absorbing materials also cushion the fall.
The system has been developed by Ishida Europe, working with Sucralliance. Ishida also produces circular weighers, but claims to be the only company manufacturing linear weighers
The content in this entry has been obtained from publicly available information sources only (e.g. press releases, website and trade press articles) and is subject to completion of a validation process with the technology supplier.

Potential Benefits

A potential benefit from this system is reduced product waste arising during the check-weighing and packing process, combined with improved efficiency. It is reported that Sucralliance achieved speeds of 50 packs per minute for 150g packs and ensured 99.5% of confectionary was unbroken with the new installation at their factory in Grenoble, France. Previously, to achieve this speed and level of quality required four workers packing by hand.
The manufacturers state that the linear system is around 20% slower than a circular system and slightly more expensive, but in the correct circumstances will provide improved efficiency overall.

The system has been developed by Ishida Europe working with Sucralliance.

Consultant View

Taking advantage of this technology would require a capital investment, so feasibility would depend upon remaining life time of existing equipment and proposed capital investment cycles.
