SP-600 This is our standard duty machine, capable of high capacity separation with production of a highly manageable stack of solids between 25% and 30% dry matter. The SP-600 is perfect 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-600 HD

SP-600HD Developed exclusively for the preparation of the feedstock for DariTech, Inc.’s 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-800 HD

SP-800HD is a longer, higher capacity, faster turning separator for larger dairies with a need for solids greater than 35% dry for purposes such as green bedding.


DariTech, Inc. has developed a reliable, self cleaning manure separator at a reasonable price for the dairy industry.  The internally fed rotary screen with an external spray bar concept was DariTech Inc., to improvement on the older rotary screen separator. Now we are pleased and proud to introduce the DT360, our new rotary style manure separator.

The DT360 has many features which are attractive to dairymen as they balance performance, reliability and labor and maintenance costs with the manure handling challenges facing today’s dairies. We understand that your time, as well as your crew’s, are best spent on tasks which make the dairy more productive, time spent maintaining and cleaning screens is all but eliminated.
