“At fermentere” stammer fra latin og betyder “at bringe til gære”. Det beskriver i alt sin enkelthed faktisk, hvad fermentering går ud på: Når du fermenterer din mad, konserverer du den ved at sætte gang i en gæringsproces, hvor de

200L Fermentor

A 200L fermentor is used to carry out biofermentation processes on a pilot scale. Upscaling to 200L is often used after testing at 20L to qualify the product or process before further upscaling (e.g. to 2000L).

A fermentation process is used, among other things, for the development of food, feed, or food ingredients (e.g. proteins). The biomass, which can consist of microorganisms or plant material, undergoes a transformation using, for example, yeast or bacteria. 

In a biofermentation process, biotechnology is used to select, modify, and optimize microorganisms in order to produce specific biosolutions. In biofermentation processes, the role of biotechnology is to exploit microorganisms such as bacteria, yeast, fungi, or plant cells for the production of desired biosolutions. 

The biofermentation process has the potential to produce a wide range of biosolutions for industries such as food production, biochemical production, and pharmaceutical production.

How can the Danish Technological Institute help you?

The 200L fermentor is a part of the Danish Technological Institute's Biosolution Technology Center, where we offer laboratory and pilot testing in the field of biorefining and biofermentation. Our equipment is often involved as a subprocess in the development of innovative products - either in research and development projects or in direct collaborations with companies.
