Green Bedding and Digestate separators from Greencrop
G reen bedding has now become of great interest in the UK after its popularity in the USA and Europe for some years . Our neighbours in Holland have been using green bedding for six years and have converted to the system both on mats and deep bedding ( 85 % of all new cubicles in Holland have

gone to deep bedding ). Visscher have been involved from the beginning , and have developed an automatic separator system and have over 450 working units in Holland ( both static and mobile ). They also have over 90 in Germany , plus units in Italy , Belgium , Denmark , Portugal , Lapland and now a number of units installed in the UK .
After a full review the process has now been accepted in the UK . The Visscher / Sepcom green bedding separator is designed to produce recycled bedding material from the separated slurry . The benefits of this system give cow ’ s better comfort in the cubicle , helps keep them cleaner and help to reduce mastitis levels in the heard , whilst also reducing bedding costs . The separator has a lower electrical demand than other machines as it is fitted with a 5.5kw motor . Due to its larger screen area and auto adjusting head , its power requirement is reduced . The Visscher / Sepcom will produce bedding with a dry matter content of 33-37 per cent .
The unique polymer sectional auger as standard , which has proved itself on other Sepcom separators for its cleaning ability during use . As well as significant advantages in keeping the screens cleaner , it aids a higher degree of separation than a steel screw system . The final part of the separation is by a Visscher screen mounted in the centre of the solid core , this allows the moisture from the inside of the solids out through the centre , thus not trying to squeeze all of the liquid to the outside . This works in conjunction with the Patented Visscher automatic press module head which adapts the counter – pressure to the medium`s consistency . This allows the module to automatically apply optimum pressing force . The system will continuously adjust itself to the pre-set value and this has a very close relationship with the dry matter percentage and capacity .
The PLC controller can be adjusted to the dry matter content / mass balance desired for nutrients and dryness . Only about 70 % of the daily produced slurry is needed for bedding , a simple turn of a dial on the panel decreases the amps , saving energy costs and produces a faster standard separation DM for spreading on to the land . This means you don ’ t have to climb up and adjust the separator outlet manually every time . Pumps and agitators The consistency and homogeneity of the slurry helps ensure a good result . It is therefore important to choose the right agitation and pump in connection with the green bedding separator .
Greencrop can provide a range of electrical mixers for the reception pits , plus for the most efficient installation we would recommend the Visscher cutting mill and positive displacement pump system .
. The capacity is about 5-20 m3 per hour . The worm pump is characterised by a constant flow of slurry , irrespective of its composition .
The rota is hardened to cope with any small hard particles , which would harm a standard positive displacement pump .
Through the control panel the pump and auto-head work together to feed the correct amount of slurry at any one time , and if there becomes a blockage or lack of product , the system will automatically shut down .
Greencrop can also offer a full range of Sepcom separators for AD plants be it slurry- field crop or food , feed stocks . Horizontal or the unique vertical machines are in use on many UK Plants ...
