Multipond Wägetechnik GmbH (Germany) - With annual growth rates of two digits and an annual production of more than 100,000 tons, the company H. & J. Brüggen KG is one of the leading and fastest growing cereal manufacturers in the world. The manufacturer´s large product range requires maximum flexibility in the production and final packaging. Therefore, the company relies on the multihead weighers from MULTIPOND for weighing the products for good reasons. More than 35 machines installes already at the total of four production locations in Germany, Poland and France speak for themselves. Only recently, another multihead weigher of the type MP 3601-FFC-S5 has been installed in the Lübeck factory.

The weighing system is a 36-head Twin memory hopper weigher which is used for weighing of various muesli-mixtures with up to three components for target weights up to 1,000 g. Transferring the individual partial portions to the packaging in the exactly correct mixing ration was decisive for the purchase of the multihead weigher at Brüggen.

The individual components of the muesli mixtures are supplied to the weigher here via two MULTIPOND vibratory conveyers and via 2 tubes – for the free-flowing components such as oat flakes or cornflakes. Two ultrasonic probes above the product separation provide even product feed to the weigher in the area of the vibratory feeders.

The weigher is equipped with a 4-way product separation and has two separate outlets for filling of two vertical VFFS (vertical from fill seal machine). Individual sectors – feed trays and chutes – have been provided with a special surface in order to also be able to weigh difficult, sticky products without problems.

Combining, mixing, counting and dosing are included as standard as basic functions in the weigher software. The weigher described here mainly operates in a combination of the combination and patented MULTIPOND dosing modes. Depending on the application, the target weights of one or more supcomponents are determined in the traditional combining mode while the weights of other subcomponents are determined in the patented dosing mode.

“One of the reasons why Brüggen comes back to the weighing systems of MULTIPOND again and again is the high degree of flexibility in relation to the weigher software”, says Stephan von Melle, Technical Director of the company. “The development factor in this area is established so high, unlike any other supplier. Our own ideas and imagination about the individual projects are always implemented one hundred percent here. However, software and operator guidance of all systems are designed so that these are easy to operate”.

After the actual weighing process, the accurate weigh portions are transferred via the two funnel outlet to the two VFFS (vertical form fill seal machine). The performance potential of the multihead weigher is not yet exhausted with the 2 x 60 weighings per minute required by Brüggen.

Maximum accuracy is achieved using calibration systems integrated in each load cell which make completely automatic calibration possible even during the production. “With their high reliability and effectiveness, the system certainly represents the core for the line availability”, says von Melle.

Stephan von Melle is also satisfied with the collaboration with MULTIPOND. “The fast reaction of this special machine manufacturer is particularly beneficial here. The technical and advisory support of the MULTIPOND service employees has already contributed to some optimization processes in our final packaging”.

MULTIPOND is the sales and service division of the German based manufacturing company ATOMA which has been established since 1946. The first automatic weighing system for the packaging industry was launched in 1963. It is positioned as the market leading innovator in the design and manufacture of customized multihead weighing systems for the packaging industry. Headquarters and manufacturing facilities are in Waldkraiburg, Germany, about 65km east of Munich. Beside the global network of sales and service representatives, there are four wholly owned sales and service subsidiaries in the UK, the Netherlands, France and the US.
