85 ARTICLE MILLER / december 2021 “Together with the palletizing robots, Greif-Velox was able to deliver the most compact system possible,” says Wieler. It also saves time. Changing the bag format does not require a meticulous adjustment to the parameters, which would be time-consuming – instead the process parameters can be set with the press of a button after the correct data is entered once. The same is true for the product changeover. When saved, product-related machine parameters can be restored effortlessly. Residual product emptying: Fast, hygienic product changeover without any contamination Fast, hygienic product changeover is made possi- ble through a residual product emptying process us- ing a special container flushing system. Thanks in part to an innovative air flushing system and a conveyor belt that removes product residue, significantly less residual product is left in the container than is stan- dard in the industry. Depending on the volumes being bagged, this could mean annual savings in the five-fig- ure range. Additionally, the system is equipped with a special base that folds open pneumatically to emp- ty product residue. “The systems are designed to be able to run empty very efficiently,” says Wieler. “This significantly reduces cleaning times.” This reduces cleaning time both in and out of the ma- chine, improving employee safety in the factory in gen- eral. The clean filling process – which includes special return air nozzles with inflatable cuffs and return airflow – drastically reduces dust formation, especially when working with fine-grained products. “On conventional machines, you always have a rela- tively large amount of dust blowback from the valves, which requires more cleaning effort,” says Wieler. “Now, we have very little contamination during normal opera- tions.” REDUCTION OF RECALL COSTS To lower recall costs and ensure high product quality, the machine at GoodMills Deutschland is also equipped with a space-saving combined checker system, which has a metal detector with a detection accuracy of under two millimeters and also monitors the weight. Possible contamination can thus be detected early and removed before the products make it to the end customer, pre- venting potential product recalls that are both expensive and damaging to the reputation. A particularly robust seal on the bags further reduces recall costs: The BVPV 4.40 is equipped with the ValvoSeal ultrasound sealing unit, which seals valve bags cleanly and securely with a waf- fle-shaped pattern. This enables an extremely tight seal and, according to a study conducted by TH Lübeck, up to 60% greater resistance to tearing when compared to con- The Velopack high-performance robot delivers fully automatic palletizing.
