Mobile weighing for cleanrooms
Mobile weighing solution offers precise weighing and saves costs through flexible use
Key facts
Boehringer Ingelheim uses ultrafiltration vessels when manufacturing its pharmaceutical products under clean room conditions. These vessels must be weighed precisely and transported to other production areas or, in some cases, put into storage. When it comes to weighing them, a mobile weighing solution that can be cleaned with ease and transported safely is required.
Application & Product
To meet Boehringer Ingelheim’s requirements, Vienna-based system manufacturer and partner to Minebea Intec Baumgartner & Co. designed a mobile process vessel with integrated weighing electronics and modules from Minebea Intec.
Customer benefits
This mobile weighing solution enables precise on-site weighing and reduces costs thanks to its flexibility and the speed with which it is ready for use again. Its hygienic design enables complete inspections to be performed and ensures ease of cleaning to protect against contamination.
Boehringer Ingelheim relies on UDF vessels, which are put to use under clean room conditions – both after ultrafiltration and before the product filling stage. The pharmaceutical company ordered a mobile weighing solution for a 50 l ultrafiltration vessel weighing 320 kg in total. The extended remit required the solution to be resistant to cleaning products, be able to withstand transportation stresses and to include the option of connecting the weighing station to the existing PLC.
Manufacturing systems used in the pharmaceutical industry have to comply with stringent hygiene requirements. Thorough cleaning processes using abrasive cleaning agents are a must and they have to be verifiable, too. What’s more, there are busy routes used to transport materials to different production areas for subsequent manufacturing steps. In light of this, the mobile weighing solution has to be able to withstand frequent transportation and intense cleaning. This is a challenge for the process vessel, load cells and connected components alike.
Based on Boehringer Ingelheim’s specific requirements, the Vienna-based system manufacturer Baumgartner & Co. designed a mobile process vessel with integrated weighing technology using the three hygienic weighing modules Contego from Minebea Intec. The weighing modules Contego have a hygienic design. Thanks to its compact design, the solution could be easily integrated into the mobile vessel, while retaining its full functionality and complying with hygiene requirements. In fact, the design consistently avoided details that could pose poor hygiene problems – such as indentations, covers and open threads - thus enabling effective cleaning without placing excessive demands on time or using too many cleaning products. The hygienic design saves money and prevents Boehringer Ingelheim products from becoming contaminated. At the same time, the fundamental “weighing on wheels” concept ensures that the manufacturing system is quickly ready for use again and that efficiency levels are boosted.
