TIETJEN Verfahrenstechnik GmbH products

Tietjen’s biomass shredder BMS is a vertical grinder that efficiently and homogeneously processes biomass for anaerobic digestion. By de-fibering, crushing and grinding with Tietjen’s BMS, a higher gas yield is achieved, and difficult substrates can be made usable in the digester.

The Hammer Mill GDX is designed for grinding compound feed, with frequently changing requirements, in the feed structure. The fully automatic screen change also makes it possible to quickly change between two screen perforations by mouse click, and while the machine is running. Together with a frequency converter (FC) controlled drive, this results in a maximum of variability in terms of the grain spectrum.

The AGS series air-gravity separator is well suited for the continuous separation of all types of foreign bodies from free-flowing bulk materials. Dosing occurs in combination with a dosing screw, which can also convey non-free-flowing bulk materials such as flours and bridge conveyor lines. The design guarantees optimum double foreign object protection thanks to a magnetic cascade and wind sifting for non-magnetic contaminants. The AGS housing is very compact, the centre distance between input and output is only 245 mm. The unit is pressure shock resistant in accordance with the latest standards, tested in practice and certified.

The depackaging machine DRM is used for processing food waste like municipal and commercial organic waste or source separated organics (sso). With a high throughput our equipment is designed for professional food waste recycling. Here, our system achieves the highest degrees of purity. Today, the separation mill DRM is in continuous use in various food waste recycling plants: it unpacks and homogenizes the food waste and thus optimally prepares it for recycling in biogas plants.
