Krones Processing

The Group’s process technology expertise unified under a single brand

Process technology has been a core expertise of Krones for many decades. Until now, this broad range of solutions and technologies has been represented by various companies and brands within the Group, each specialising in specific industries, technologies or regions.

Krones is now streamlining the market presence of its process technology business under a single performance brand:Krones Processing.

The goal is to make the Group’s comprehensive process technology portfolio more transparent and easier to access. The existing organisation, the companies and their expertise will remain unchanged. What is new is the unified brand identity, which highlights the wide range of competences and technologies within the process technology portfolio.

Bioreactor from Krones

Process technology for the fermentative production of alternative proteins

To be able to continue to supply the world's growing population with vital nutrients and at the same time use the available resources sparingly, the nature of protein sources will change in the future.The solution? Alternative proteins. This is because food of animal origin can be replaced with plant proteins, precision fermentation or cultivation of biomass, all of which provide equivalent products. And the increased efficiency in production means that natural resources are used more efficiently.Krones supports food manufacturers in the production of alternative proteins – both during design of the process technology and when scaling up to a higher production output.

At a glance

  • Process expertise and market know-how in the food and beverage industry
  • Ideally coordinated technological solutions
  • Economic conceptual design of the complete installation
  • Energy-efficient process

A concrete example of the cultivation and replication of such proteins is biomass production. Here, cells are placed in a tank where cell multiplication is initiated. And this is exactly where Krones comes into play with its own bioreactor. The key factor: It was developed on the basis of the proven fermentation unit Poseidon(opens external link in a new tab) from Steinecker from brewing technology and works with a circulation unit instead of an agitator. In addition, the recirculation unit is equipped with aseptic valve technology from Evoguard and a low-shear aseptic pump. Integrated in a sterile tank with steam or condensate barrier, cells can be cultivated or fermentations carried out.

Requirements to a bioreactor

Homogenization
  • to prevent sedimentation of cells
Mixing
  • to provide adequate mass transfer of nutrients within the overall tank volume 
  • to provide adequate heat transfer between the tempering jacket and the tank contents
Aeration
  • to supply the cells with oxygen
Feeding
  • to supply the cells with nutrients and other ingredients
Sampling 
Sterile environment
  • to prevent contamination

The recirculation of the tank volume under sterile conditions is the key task of an efficient fermentation process.

Dynamic fermentation

Recirculation for an efficient fermentation

 

Flexibility and scalability

  • Available tank sizes: between 500 and 200,000 litres
  • Prototype on a laboratory scale, validation and test capacities possible with partners
  • Various outlet housings at different heights within the tank: are not only used as outlet but also as inlet
    • Different flow directions possible (for homogenization, aeration, fluidized bed process or sedimentation for cell harvesting)
  • Flexibility through pipe diameter dimensioning and adjustment of the volume flows in the pipe system
  • Fed-batch or continuous mode possible

Cost and process efficiency

  • Continuous mixing in a recirculation circuit: Use of a recirculation unit instead of an agitator
  • Can be retrofitted into existing tanks
  • Maintainability through easy accessibility of seals, field devices and motors
  • Fewer spray shadows during cleaning for an improved cleaning result
  • Representative measurement of process parameters by means of continuous flow through the field devices in the circuit

Process steps

Tank construction – From tank to bioreactor

Our expertise

  • Manufacturing halls specially designed for tank construction
  • Automated processes for tank dome and shell production
  • Precisely coordinated work steps, carried out by qualified welders
  • High-performance and program-controlled production machines for cutting, drawing and welding work
  • Highest quality through a globally recognised and standardised welding and inspection procedure
  • Surface treatment with polishing and pickling solutions, including ceramic blasting of the outer surfaces

Benefits to you

Efficient solution for high production outputs

The use of a recirculation unit enables the realisation of high production volumes, and the costs still remain within reasonable limits.

Use of approved technology

The bioreactor was developed on the basis of the Steinecker Poseidon(opens external link in a new tab) fermentation unit, well-tried from the brewing industry, that has already successfully proven its worth in practical use at numerous breweries.

Many years of experience in plant engineering

Decades of expertise in process technology are deeply ingrained within the Krones group. Especially, the expertise of the subsidiary Steinecker in the brewing industry can also be adapted to biotechnological applications. Customers who want to open up completely new markets in the area of vegan food alternatives are now also benefiting from this knowledge and are utilising Steinecker's proventechnology to do so.
