Roller Gate Case Study: Enhancing Soybean Meal Export

The United States plays a crucial role in the global soybean market, with Gulf Coast ports serving as a primary hub for exports. A significant portion of this export volume is soybean meal, a vital component in animal feed worldwide. Efficient and reliable material handling is paramount to maintaining this flow, ensuring that facilities can meet the demands of international trade without costly delays or equipment failures.

When a major agricultural processor and exporter undertook a multi-million dollar expansion at their Louisiana facility, they required robust and dependable equipment to handle soybean meal, hulls, and various grains. This case study focuses on one piece of equipment from this large-scale project: a custom-designed Vortex Roller Gate. This gate is representative of the high-performance solutions sourced to optimize the facility's finished product handling systems, specifically for meal just before it is loaded for export.

The Challenge: Reliable Shut-Off for Abrasive Materials

The client required several slide gates capable of providing a positive seal and reliable service in a demanding environment. The system handles large volumes of soybean meal, an abrasive material that can cause significant wear on standard equipment. A key requirement was a gate that could close on a flowing column of material without jamming or leaking, and that would offer a long service life with minimal maintenance downtime. The gate also needed to withstand continuous service temperatures up to 250°F (122°C).

The Vortex Solution: A Custom 48" x 30" Roller Gate

Vortex engineered a Model RSFA48X30V1-HT3-SR-RP-E147111 Roller Gate to meet the specific demands of the application. This rectangular gate features a 304 stainless steel frame, blade, and material contact surfaces, providing excellent corrosion and abrasion resistance.

Several key design features make this Roller Gate the ideal solution:

• Vortex Model No. RSFA48X30V1-HT3-SR-RP-E147111, 48" X 30" Rectangular Stainless Frame Roller Gate Valve.
• Valve body, blade and seal retainers are 304 stainless steel.  
• Material contact is 304 stainless steel and polymer.
• Milled access slots in side frame allows removal and replacement of bonnet seals while the gate valve remains in service.  
• Valve body is modified to accept proximity switches (plugged if indication switches are not utilized).
• QTY (2) double acting air cylinder actuator equipped with a magno-piston for use with magnetic reed position indication switches.
• (HT3) - Valve is rated for 250˚F(122˚C) maximum continuous service.  PET side seals and upper and lower bonnet seals are live loaded and silicone rubber backed.  Valve also includes cam-adjustable slide rollers and PET roller spacers.  End seal and bonnet blade guides are PET.
• (SR) - Stainless steel and bronze cam-adjustable slide rollers replace polymer cam-adjustable slide rollers
• (RP) - Outlet flange pattern is drilled to match return pan transition.  Return pan is sealed and assembled onto gate valve.
• (E147111) - LARGE RECTANGULAR ROLLER GATE. SET UP FOR 60 PSI. 6” FRAME, 1/2” BLADE, TWO 8” BORE AIR CYLINDERS. DESIGNED TO CLOSE ON FLOWING PRODUCT. THREAD SEALANT OTHER THAN TEFLON TAPE TO BE USED ON ANY THREADED FITTING.

A Critical Component in a Major Expansion

This customized Vortex Roller Gate, along with several other Vortex valves provided for the project, plays a vital role in the client's expanded export capabilities. By delivering a positive seal, resisting abrasion, and offering features that simplify maintenance, the Roller Gate ensures the reliability and efficiency of the finished meal handling circuit.
