Ishida is taking the accurate weighing of mixed products – such as nuts, confectionery and convenience meals – to a new level of sophistication and accuracy with the introduction of a 36-head multihead weigher. In particular, the new CCW-R-236 is able to ensure the correct amount of high-value products with no need for overfilling.
The new weigher is capable of handling and mixing up to eight different products at high speeds, with a top speed of up to 360 weighments per minute for a single product.
The mix weighing process means each section of the machine acts as an individual weigher, allowing each ingredient in the mix to be given a specific target weight to ensure that the final product contains exactly the right proportion. Equally important, each section can be specified with different contact parts in order to cope with the special characteristics of difficult-to-handle products, such as sticky items including raisins or jellies, without compromising speed or accuracy.
The CCW-R-236 incorporates Ishida’s proven R Series technology, including pulse width modulation (PWM), which ensures a controlled and more predictable flow of product through the machine, and unique combination calculation software, five-stage digital filter, anti-floor vibration and Ishida-made load cells that enable the weigher to maintain excellent accuracy at these high speeds.
This accuracy has further reduced product giveaway, meaning significantly more packs can be produced from the same amount of product, while faster calculation speeds allow the weigher to calculate several possible final combinations each time. As a result, the missed cycles that can occur in competitor machines have been all but eliminated.
Easy-to-follow graphic displays on the remote control unit (RCU) keep operators fully informed of machine status, weighing results and any action needed, while information such as presets or software upgrades can be rapidly downloaded via a network. Equally important, the RCU software uses a Windows XP® platform, enabling weighing data to be made readily available to factory managers anywhere in the company.
One-touch presets and tool-free removal and replacement of hoppers and feeders minimise downtime. Packs can also be photographed to provide an easy reference for operators selecting presets.
“Our new CCW-R-236 offers the perfect balance of consumer satisfaction and high pack yield,” comments Paul Griffin, marketing director of Ishida Europe. “Each pack contains the expected amount of high-value components, yet virtually no overfilling is needed to achieve this.”
