Trident Roller Press Main Image

Technology Description:

The Trident Roller Press is a durable and effective separator for organic material. It is specifically designed to improve the manure management on dairy farms. We see the most effective results when the roller press is placed after a primary separator that captures the manure solids. Depending on the farm’s objectives it can also be implemented as the first line of separation equipment.

The 36”, 48” or 72” roller press features a heavy-duty screen roller, a Duro 40 roller and two air bags that regulate the output dry matter. The press is commonly used after a Rotary Screen and can reduce the moisture content to 72-80%. The inlet collection tray and the effluent tank is manufactured from non-corrosive stainless steel. The adjustable discharge scraper is made of durable UHMW plastic. The dewatered manure solids are discharged onto a conveyor or directly into a storage bay. The sloped effluent tank with its 6” outlet allows for effective discharge of the separated liquid. The integrated CIP system ensures automated cleaning of the perforated drum. The machine also features Trident’s one-way clutch mechanism that allows free-wheeling the drum back to prevent machine downtime potentially caused by larger foreign objects. Long lasting, dependable components guarantee trouble free operation for many years.

Technology Strengths,Weaknesses and Critical Indicators

Slope Screen technologies:

  • Produces fiber for bedding, soil amendment and compost
  • Used extensively on dairies across the country to reduce concerns associated with storage and application
  • Do not significantly reduce nutrients from the manure stream
  • Can utilize many types of technology like slope screen, screw press, rotary drum and others
  • Used before many other technologies to remove coarse solids
  • Minimal maintenance and operator time required
  • Proven technology for nitrogen recovery, phosphorous recovery, storage reduction, GHG reduction, and odor control but with limited impact in all cases

Newtrient Comments/Opinions:

Coarse solids separation technologies:

  • Produces fiber for bedding, soil amendment and compost
  • Used extensively on dairies across the country to reduce storage and application concerns
  • Does not significantly reduce nutrients from the manure stream
  • Can utilize many types of technology like slope screen, screw press, rotary drum and others
  • Used before many other technologies to remove coarse solids
  • Minimal maintenance and operator time required

 

In addition to the screw presses that have been designed and sold by Trident Processes LLC over the years, they now offer a roller press option for those applications that require even drier solids than can be achieved with a screw press alone. As with all Trident equipment the roller press is designed and built to be robust and these units should be considered for any application that needs extra drying and reliable and efficient course solids removal.
