Wierzejki, one of Poland’s largest meat manufacturers has installed a new Ishida multihead weigher, significantly improving the line throughputs
This has been achieved when packing the company’s new range of dumplings, with the investment resulting in a payback of approximately 18 months. Previously a laborious and time-consuming hand packing operation that required six people to achieve the 1.2 tonnes of dumplings to be packed every hour, the Ishida CCW-RVE-214W-1S-30-WP has considerably reduced overall losses from 5% to less that 2% per pack.
The new product weighs dumplings mainly into 400g packs but is able to handle a large variety of pack weights, including multiple weighments into the same pack for very large foodservice packs, using the 'multi-dump' mode. This gives Wierzejki the flexibility to respond quickly to market and customer demands. Equally important, the consistency of pack weights that the Ishida weigher delivers helps to enhance the consumer experience to support Wierzejki’s premium brand image.
Featuring a patented Pulse Width Modulation (PWM) technology, the Ishida RVE model provides greater control of the infeed of product at the top of the weigher and during transfer to the hoppers. By being able to automatically vary both the amplitude and duration of vibration, the vibratory feeders deliver a controlled and consistent flow of product in order to maintain speed and efficiencies while virtually eliminating overfill in the hoppers. Embossed surfaces facilitate a smooth product flow throughout the weigher. A special distribution system beneath the Ishida weigher provides a fast and efficient transfer of dumplings into the thermoforming machine.
Thanks to its intuitive touch screen operation, the Ishida multihead which is in operation for 12 hours each day requires only one operator to supervise the line, with set up and changeovers being easy to undertake. Moreover, the weigher’s modular design allows easy removal and replacement of contact parts for a fast and thorough daily clean down.
This is the second Ishida multihead weigher to be installed at Wierzejki and like the first, which Wierzejki reports has been working perfectly for over two years, the new model has proved extremely reliable. The weigher was installed by Ishida’s long term local partner in Poland, Fenix Systems, with the installation being completed in under two days. Fenix also hosted a a one-day workshop to help operators familiarise themselves with the machine, as well as providing ongoing remote technical support.
“Precision is everything in our business and this was the driving force behind our investment in the Ishida solution,” said Adam Zdanowski from Wierzejki. “Our new Ishida weigher has given us increased accuracy and efficiency, and no downtime, together with excellent service and support, all of which are delivering significant improvements to the bottom line.”
