Reliable Depackaging Machine for Organic waste

The separation mill DRM is a depackaging machine for municipal and commercial organic waste, source separated organics (sso) as well as packaged food waste. With a throughput of up to 25t/h, the machine is designed for professional food and biowaste recycling. Here, our system achieves the highest degrees of purity.

Today, the separation mill DRM is in continuous use in various recycling plants: it unpacks and homogenizes the food waste and thus optimally prepares it for recycling in biogas plants.

Separation mill DRM

Depackaging machine: focus on economic efficiency

High degree of purity

High purity in the separation process of organic waste and packaged food waste. Further increase in purity with complete depackaging systems and plant engineering.

20 % dry matter content

Low water consumption in the separation and depackaging process means a lower investment in the fermenter of the biogas plant or a reduction in logistics costs.

Tested in practice for 10 years!

The separation mill has been in continuous operation in several German food recycling plants for more than 10 years. It achieves a very high machine availability even with difficult requirements and in multi-shift operation.

Highest purity and highest biomass yield

Double rotor for the depackaging machine

depackaging machine cross-section

Our separation mill DRM works with the double rotor principle. Only this principle allows our depackaging machine to achieve the high purity required for the processing of mixed organic waste. At the same time the separation mill DRM is characterized by high throughput and process reliability.

Advantages of the double rotor:

  • The wide beaters of the first rotor open packages reliably and gently without crushing them too much.
  • Due to the small distance between the beater and the screen, the biomass is pressed through the screen without adding much liquid.
  • The second rotor takes over the material and repeats the process again.
  • The pressed-out packaging material is very light and is ejected from the side of the depackaging machine by centrifugal force. Foreign matter that still contains too much organic material remains in the machine.
Economical and efficient

Low water and energy consumption of the depacker

The separation mill DRM separates biowaste and packaging without adding water or liquid. Only in the case of very dry organic waste a minimal addition of liquid through integrated nozzles can improve the separation performance.

This is how our separation and depackaging systems achieve their high efficiency, and the low-resource separation saves twice:

  • On the one hand, because hardly any water needs to be used for separation and thus the organic concentration of 20% is very high.
  • On the other hand, a high organic concentration for biogas production means a lower investment in the fermenter, as it can be designed smaller.

This is the only way to achieve a high economic efficiency with our separation and depackaging systems.

Always in use

High machine availability of the depacking machine

Thanks to its robust stainless steel construction, the separation mill DRM can withstand the most demanding separation tasks and has also proven itself in 24/7 multi-shift operation in waste disposal plants.

The built-in hydraulics make it easy for operators of food recycling facilities to open the machine’s housing halves for maintenance or remove massive interfering materials quickly. Essential spare parts that only need to be replaced after a few years can be easily changed, so that a very long service life of the depackaging equipment is achieved.

System competence increases biomass yield and purity

Screw press for dewatering of biowaste

The depackaging machine does not stand alone in the waste treatment process. Only with the optimal coordination of the individual process steps the highest performance, efficiency and purity in organic waste treatment are achieved. Here you see the depackaging system together with our screw press PRS for further dewatering of the packaging.
