New solutions often arise from the intelligent combination of proven technologies and established components. This was recently the case with a task set by a customer from the pharmaceutical industry.
The challenge: Before the powder is further processed in a packaging machine, it must be checked by a metal detector for any metallic foreign objects it may contain. In order to achieve a high level of sensitivity, the powder must be checked in free fall. However, the metal detector cannot be installed on the packaging machine because the ceiling height is too low and the position is inconvenient for operation.
The solution: A CEIA metal detector is installed below a Volkmann vacuum conveyor on a Volkmann mobile lifting column. With the help of the height-adjustable column, the product discharge of the metal detector is adjusted to the correct height to match the mobile container. The vacuum conveyor can also be lowered to a height that allows the mobile lifting column to pass through doors and into the washroom.
The powder is transported by vacuum conveying, for example, from an IBC container to the mobile lifting column and from there to the metal detector. Metallic foreign objects are sorted out and collected in a separate bottle. The tested powder is collected in a mobile container. Another vacuum conveyor is installed at the packaging machine, which draws the material from this container.
The inspection and separation of metal parts can be carried out in the immediate vicinity of the packaging machine. However, this is also possible in more distant areas of production.
Installing the metal detector on a mobile lifting column allows for flexible use in production. In addition, the system can be moved to the appropriate area for cleaning.
The mobile lifting column was designed in close cooperation with our Polish partner Trade & Consult.
In the video, we show some impressions of the lift truck in operation. The footage was shot in our test centre after successful FAT and shortly before shipment to our customer. This also explains the presence of a packaging machine (seen as a box covered with foil) and the operator’s clothing, which is not suitable for pharmaceutical use.
