Bosch Xelum, the latest machine from Bosch for dosing of active pharmaceutical ingredients

At Achema 2018 in mid-June at Frankfurt, Bosch Packaging Technology will introduce its latest R&D device for the continuous production of oral solid dosage (OSD) forms. The platform ensures a short time to market and optimum dosing of active pharmaceutical ingredients (APIs). “The new laboratory device is based on our Xelum production platform that we presented last year,” says Fritz-Martin Scholz, product manager at the Bosch subsidiary Hüttlin. “The separated process steps of batch production take place one after the other and without interruption. This leads to shorter cycle times, lower production costs and high flexibility.” With the Xelum R&D, Bosch offers a platform that offers an ideal start to continuous manufacturing.

Precise and reliable dosing

As opposed to the common complex mass flow rate, excipients and active ingredients are dosed as a discrete mass in the Xelum R&D. This makes it possible to dose even smallest amounts of APIs of less than 1%. The system doses, mixes and granulates individual packages, so-called X-keys, which continuously run through the process chain and are removed successively from the machine as packages into bins. “This way we reduce not only process complexity, but also the system’s failure susceptibility, while increasing both accuracy and quality of the end product. Moreover, the product is traceable at all times,” says Scholz. Depending on requirements, up to four loss-in-weight feeders can be used.

Since the Xelum R&D uses the same components for dosing, mixing and granulating as the Xelum production platform from Bosch, process parameters are identical and can be directly transferred 1:1. “Scale-up becomes obsolete, which reduces development time and API usage, since elaborate tests are no longer necessary,” Scholz explains. Material flow from dosing to emptying takes place in a closed process (bin-to-bin) to ensure the highest safety.

The benefits of the fluid bed

Current continuous production systems for wet granulation mostly use twin screw granulators. The Xelum system relies on fluid bed processors – based on a proven technology developed by the Bosch subsidiary Hüttlin. In the fluid bed, granulation and drying take place in the same process chamber. “This eliminates the need to transfer wet granules, which in turn has a positive effect on the system’s reliability,” Scholz emphasizes. Pharmaceutical manufacturers obtain granulates with the desired characteristics – including unimodal particle size distribution, as well as excellent flow and tableting properties combined with high production yields.

The controls of the Xelum R&D correspond to a modern production system. All relevant process parameters are continuously recorded. Both the production and the product transfer, as well as the cleaning process are recipe-controlled and ensure reproducible results. The user-friendly handling of the system is complemented by a DoE (Design of Experiment) software support. Bosch Packaging Technology will be at Achema in Hall 3.1 Stand C71

The impact, resilience, and growth of responsible packaging in a wide region are daily chronicled by Packaging South Asia.

A multi-channel B2B publication and digital platform such as Packaging South Asia is always aware of the prospect of new beginnings and renewal. Its 16-year-old print monthly, based in New Delhi, India has demonstrated its commitment to progress and growth. The Indian and Asian packaging industries have shown resilience in the face of ongoing challenges over the past three years.

As we present our publishing plan for 2023, India’s real GDP growth for the financial year ending 31 March 2023 will reach 6.3%. Packaging industry growth has exceeded GDP growth even when allowing for inflation in the past three years.

The capacity for flexible film manufacturing in India increased by 33% over the past three years. With orders in place, we expect another 33% capacity addition from 2023 to 2025. Capacities in monocartons, corrugation, aseptic liquid packaging, and labels have grown similarly. The numbers are positive for most of the economies in the region – our platform increasingly reaches and influences these.

Even given the disruptions of supply chains, raw material prices, and the challenge of responsible and sustainable packaging, packaging in all its creative forms and purposes has significant headroom to grow in India and Asia. Our context and coverage engulf the entire packaging supply chain – from concept to shelf and further – to waste collection and recycling. We target brand owners, product managers, raw material suppliers, packaging designers and converters, and recyclers.
