Problem: an overwhelming excess of fermentation residues and manure

Solution: a RHINO agricultural dryer from RHS

What can you do with excess fermentation residues or manure? Both of these can be stored, disposed of or burnt. These solutions all come at a price. Moreover, with these solutions the high concentrations of valuable nutrients such as potassium, phosphate and nitrogen go unused. And in regions with a nutrient surplus, such as Emsland or the western Münsterland region, depositing these substances on arable land is not always advisable.

Then there is the possibility of drying the material out professionally. This is not free of charge either, but - it pays off many times over! Only through thorough drying can the weight and volume of these outstanding waste substances be massively reduced. All forms of separation are unnecessary here. Separation is a partial step but is not an overall solution to the problem. Therefore: the best solution is to send all the material to a RHINO agricultural dryer, in either solid or liquid form, which results in a dry matter (DM) content of 85-90% and more. Now we have a wonderfully homogenous dry substance that can be used as a field or garden fertiliser. This can now be transported to agricultural or horticultural land in dump trucks or pelleted and filled into sacks for sale to domestic customers. A clear outcome: the RHINO agricultural dryer converts excesses into a finished product to enhance the environment.

RHINO Agrar for drying manure and fermentation residues

Advantages at a glance:

  • The drying principle: A large substrate surface is created by continuous mixing with two agitators using a continuous supply of hot air (patent pending)
  • Agitator dryer in a space-saving container design – no indoor area required
  • High-quality, maintenance-free drying vessel made from stainless steel
  • Maximum availability: “Runs like clockwork”, up to 8,500 hours per year
  • From this comes: a material that is astonishingly homogenous in consistency and dryness, a top-class natural fertiliser!



The supply, mixing and dosing unit (SMD)

(part of the patent applied for)
This device processes the substrate to be dried right where it belongs: in the drying vessel. As a result, all the nutrients remain completely in the dried product. Nothing of value ends up in the exhaust air. Together with the filter units installed above the drying vessel, the SMD works hard and eliminates the need to purchase an exhaust air scrubber.
The SMD supplies sulphuric acid in 96% concentration to the drying plant; here it is diluted to 20% volume for its use with water. This solution passes via a system of hoses to the drying vessel, which it enters via nine separate openings. It binds the ammonia gas (NH3) and converts it to solid ammonium sulphate [molecular formula (NH4)2SO4].
From this we obtain an excellent field and garden fertiliser. All completely automatically! And: as well as reduced investment costs, both the tedious cleaning work on an exhaust scrubber and the laborious storage of the ammonium sulphate solution (ASS), which is a pollutant to water and corrosive to concrete, are no longer necessary.

The benefits of RHINO for you as a farmer can be seen here:

  • The build-up of fermentation residues and manure is reduced to a minimum right on the site at which it gathers
  • Lower storage, transport and disposal costs allow amortisation of the drying plant in just a few years
  • You receive a long-term investment that will work reliably and with little maintenance over many years
  • You obtain a system that is operated in an environmentally friendly manner and is good for the environment
  • You save your organisation any costs for fertiliser by using the homogenous dried product on the agricultural areas while also potentially achieving revenues from distributing it as a garden fertiliser.

RHINO agrar im Einsatz

NDM Unternehmensverbund

Mit einem deutschlandweit einmaligen Engagement und der Motivation „selber anzupacken statt abzuwarten“ haben die Kommanditisten der NDM, allesamt Landwirte aus dem Kreis Borken (NRW), den Grundstein ihres gemeinsamen Unternehmens zur Gülle-Vollaufbereitung gelegt. Mit Risikobereitschaft, unternehmerischem Einsatz und nicht zuletzt auch Eigenkapital von mehr als zwei Millionen Euro haben sich Landwirte hier selbst in die Verantwortung genommen, um die Probleme ihrer viehintensiven Region Westmünsterland, insbesondere die Verminderung der Nitrateinträge ins Grundwasser, aktiv anzupacken. Das Ziel: neue Wege für eine Modernisierung der Landwirtschaft im Westmünsterland.

Die NDM Naturwertstoffe GmbH ist alleiniger Projektträger und Betreiber des ersten Innovationsstandortes zur Güllevollaufbereitung in Nordvelen.
