New processes in fermentation and downstream processing (DSP) are crucial for the future of sustainable food and ingredient production. By utilizing microorganisms, innovative companies like 21st.BIO can create high-value products that replace traditional raw materials and increase the industry's resource efficiency.
But being part of this innovative race via modern testing laboratories not only requires biotechnological expertise - it also requires reliable process equipment that supports the right pressure and temperature conditions without compromising flexibility and hygiene.
A strong recommendation during the development of a new test facility for fermentation processes for 21st.BIO was the start of a valuable collaboration that today supports the company's efforts to gain even more market share in industrial biotechnology.
With valuable technical advice, customized hose solutions and fast service, Alfotech is today 21st.BIO's preferred supplier of technical solutions that make a difference – every day.


The dynamic dance floor
Nicknamed the "dance floor", the test facility in the pilot laboratory plays a central role for 21st.BIO in developing and optimizing fermentation processes, which are sold to other companies. It serves as the backbone of an experimental and dynamic platform where various media are tested under different pressures and temperatures in a controlled environment.
System flexibility is essential. That’s why all equipment is mounted on wheels, allowing setups to be quickly adjusted and adapted to new experiments. This places high demands on the process equipment – especially the hose solutions, which are crucial for the efficient transport of liquids, steam, and cleaning agents (CIP). At the same time, the installed hose reels benefit Severin and his colleagues by making regular cleaning easier and ensuring high hygiene standards are maintained.

Reliability above all
For 21st.BIO, it's not just about price, it's about reliability. As Severin Gregersen, Fermentation & DSP Specialist, says:
If we can eliminate uncertainties by purchasing better quality process equipment, it's worth every penny. Not because we have our own production to maintain, but because we handle customer projects with tight deadlines. We simply need to be able to rely on your hose solutions to deliver within the time frame we have available.

Food-grade certification in sight
At 21st.BIO, quality and safety is not just a priority – it's a necessity. Although the company is approved for large-scale trials, it’s working strategically towards full food-grade certification. This places high demands on the process equipment, particularly the components that come into direct contact with the media. That’s why the purchased industrial hoses comply with the EC 1935/2004 regulation, ensuring that materials do not release unwanted substances into food ingredients.
But the collaboration goes beyond just deliveries. When new needs arise, Alfotech is ready with rapid support and adjustments to ensure the test facility always meets current standards. With deep expertise in both biotechnological processes and regulatory requirements, Alfotech is a valuable partner in 21st.BIO’s journey towards food-grade certification.
