About the Solution:

Daritech is the exclusive distributor of EYS Screw Press manure separators for the United States and Canada. By combining well established technology with the knowledge and wherewithal of Daritech, EYS produces an effective line of screw press manure separators.

EYS has a variety of separators to choose from depending on your goals:

  • SP-600 Is the standard duty machine, capable of high capacity manure separation with production of a highly manageable stack of solids between 25% and 30% dry matter. The SP-600 is a good fit for an operation that seeks to remove the fiber ahead of long term storage, and to stack that fiber in a neat and dry pile.
  • SP-600HD Developed exclusively for the preparation of the feedstock for Daritech’s in-vessel composter, the BeddingMaster, the SP-600HD has heavy duty components coupled to a slow turning gearbox that dries solids in excess of the 35% dry matter required for effective composting.
  • SP-800HD is a longer, higher capacity, faster turning separator for larger dairies with a need for solids greater than 32% dry for purposes such as green bedding.
Whatever your screw press manure separation needs, Daritech’s has an EYS separator for your consideration.
