Tietjen presents its new developments for the feed and petfood/aquafeed industries at VICTAM International in Utrecht, Netherlands.
The large chamber mill FD, the AGS AD Air-Gravity Separator AGS AD, and the Online Particle Size Controller OPC, all three increase the efficiency of the grinding process.


Research & Development

The amount of plastic waste is increasing from year to year. Biodegradable packaging is therefore becoming increasingly important, and not only in the food industry. Yet there are already many sustainable packaging alternatives – such as bio-film made from macroalgae. Since this process is very time-consuming and expensive, Ludwig Schmidtchen, a doctoral student, has developed a cheaper and faster manufacturing process for this film. He received help from Tietjen.


Timber industry

The full decarbonization of our energy supply to meet the 2030 climate targets requires diversification of energy sources while maintaining or improving security of supply. Sustainable wood energy is the only renewable, on-demand, baseload partner technology of photovoltaics and wind energy at power plant scale. Wood pellet fuel is already available today, is in sufficient supply in the long term through a global market, and can thus secure our energy supply and grid stability for tomorrow.

In Germany alone, about 12 million tonnes of food go to waste each year. From an energy point of view, this food waste is very valuable, as biowaste can be made into sustainable energy in biogas plants and then fed into our electricity and district heating grids. We will show you how such biowaste can be optimally recycled today with the help of state-of-the-art grinding and separation technologies.


Products & Machines

Only with optimal feeding and appropriate dosing of the feed material can the grinding plant be operated efficiently. Tietjen offers three options for feeding with the air-gravity separator (AGS series), the drum feeder (DA series) and the vibratory feeder R.
