Technology Description:

The TRIDENT Screw Press is a durable, robust and efficient piece of equipment, purpose built for making bedding material from dairy manure. The press features a screw with interrupted flighting, graduated pitch and resistor teeth. The flighting is notched and a 1/32 inch screw-screen clearance helps promote effective dewatering and low maintenance operation. The screw shaft is supported on both ends ensuring robust and low wear operation. A simple yet effective shaft seal design prevents machine failure from manure liquid entering the gearbox. An air operated outlet door allows automated output control. The produced solids are coarse and fluffy with exceptional dry matter (up to 34%), providing both cow comfort and excellent drainage characteristics, both essential requirements in today’s dairy applications. The equipment with its robust construction and corrosion resistant components is designed for long lasting operation, while reducing maintenance and operational costs. The Trident Screw Press is utilized as a component in Trident’s Bedding Recovery System, where it is implemented post the coarse fiber separation step with the Trident Rotary Screen.

Depending on the specific requirements on the farm the Screw Press can be installed with a straight or tapered screw shaft. Different screen sizes are available as well, to allow optimal performance. The Screw Press can be installed with an automation package allowing 24/7 operation without requiring operator attendance. 

Robust construction coupled with corrosion resistant components and wear resistant design assures long life. The low tolerance design eliminates the high wear issues found in other screw presses providing long life making the Trident line of screw presses reliable and economical to operate.

The Trident Screw Press is based on the proven and robust technology of the Vincent Screw Press, that was first introduced to the dairy industry in 1996. Trident is the exclusive distributor of Vincent Screw Presses in the agricultural market in U.S. and Canada.

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, in 2016 Trident Processes became the agricultural marketing representatives for Vincent screw presses are now being marketed under the Trident name. These presses represent a significantly different design than that used by most presses in the dairy industry in that the screw is supported on both ends to prevent it from ever touching the screen. This significantly reduces wear and the cost of replacing screens that is typical for most systems. This distinction combined with the robust and sturdy construction of these units make them a systems that should be considered for any application that need reliable and efficient course solids removal.
