Vortex Assist in a Coffee Roasting Plant

Several years ago, Vortex Global was approached by a systems group to discuss a new original equipment manufacturer (OEM) opportunity. This particular systems group specializes in the design and construction of roasters and other coffee processing systems.

Typically, this systems group would construct their own simple gate valves for use in their coffee roasting systems. But after attending an exhibition where Vortex products were on display, they became interested in Vortex design. In particular, they were impressed with the Orifice Gate. With that, the systems group contacted Vortex to request a trial order of Vortex Orifice Gates, to be integrated within their coffee roasting systems.

Quantity: 2 Vortex Orifice Gates
* Size: 200 mm
* Designed for indoor service
* Gate body constructed from painted carbon steel
* Gate blade & material contact areas constructed from 304 stainless steel
* Flange gasket constructed from food-grade white neoprene
* Stainless steel tubing & fittings
* Zinc-plated fasteners
* Designed without acorn nuts
* Each equipped with an Adjustable Variable Position (AVP) assembly, to provide metering capabilities.
* Each supplied with a pre-wired terminal box, for ease of installation. Terminal box is constructed from stainless steel and includes 24 VDC, NEMA 4 water/dust-tight flex conduit and fittings.
* Equipped with magnetic reed switches, for blade position feedback.

Quantity: 1 Vortex Orifice Gate
* Size: 350 mm
* Gate frame, flanges & safety covers constructed from aluminum
* Gate blade & material contact areas constructed from 304 stainless steel
* Blade is electropolished to accommodate wash-down
* Pressure plates constructed from PET polymer & are “live-loaded” with compressed natural rubber load seals
* Flange gasket constructed from food-grade white neoprene
* Rated for 82 C maximum continuous service
* Stainless steel tubing & fittings
* Sealed body, for a positive seal of air & materials across the gate & to atmosphere
* Supplied with a pre-wired terminal box, for ease of installation. Terminal box is constructed from stainless steel and includes 24 VDC, NEMA 4 water/dust-tight flex conduit and fittings. The terminal box is pre-wired to use solenoid valves and position switches.
* Equipped with a magnetic piston and proximity switches, for blade position feedback.

These three Orifice Gates were installed as part of a roasting system supplied to an American coffee processor. The system began operations in late 2016. Both the systems group and the end user customer have been very satisfied with the performance found in Vortex products; so much so that this order has resulted in many additional orders for Orifice Gates and Roller Gates to be used in this group’s systems.

Although the systems group continues to self-construct simple gate valves on occasion, they are becoming more and more familiar with the benefits found in Vortex products.

Roller Gates Assist in the Production of Horse Feed
Roller Gates Assist in the Production of Horse Feed
Last spring, Vortex consulted with a horse feed producer to assist with a process need. At this facility, the client is producing forage cubes. Upstream in the process, bales of hay are broken down and minor ingredients are added before the raw materials are formed into cubes (approximate size: 75 – 100 mm square). Once formed, the cubes are transferred into cloth silos. Below each silo, a common belt conveyor transfers forage cubes to a packaging line, where they are loaded into bulk bags. Vortex was tasked with identifying a solution for discharging forage cubes out of the cloth silos, down onto the belt conveyor. Primarily, the client is concerned with forage cube quality and thus, the cubes cannot be damaged upon gate closure. Upon careful analysis of the application, the Vortex Roller Gate was recommended. The client sourced this small-batch order as part of the “proofing” stage of its new production process. Now installed in their application, the Vortex

Wye Line Diverter Replaces Inconsistent Flap Diverters  Flour Milling Company in East Jawa, Indonesia
Wye Line Diverter Replaces Inconsistent Flap Diverters
Flour Milling Company in East Jawa, Indonesia It is not unusual for a flour mill to have problems with in-line flap diverters when installed in a pneumatic conveying system. The soft seals around the flap are exposed to direct blast abrasion from grist or wheat flour. This can create significant pressure drops in the conveying system, as well as line plugs once product is allowed to pass through the closed leg of the diverter. A flour milling company was experiencing these problems with the in-line flap diverters purchased when the mill was built. The product leakage from the diverters was creating conveying inefficiencies and significant downtime to uninstall the flap diverter and remove line plugs. The milling company decided to install Vortex Wye Line Diverters, which are ideally designed to overcome common problems associated with in-line flap diverters. The wye line design features a stainless steel sliding blade while maintaining a positive seal when the ports are closed. The diverter is also capable

Vortex Gravity Vee Diverter Replaces Flapper Diverter Materials can flow individually or both outlets simultaneously or both closed
Vortex Gravity Vee Diverter Replaces Flapper Diverter
Materials can flow individually or both outlets simultaneously or both closed Application: Vortex’s client previously utilised a flapper diverter to handle baking flour. This was problematic because, depending on the position of the blade, material was constantly flowing through one of the outlets. With the Vortex Gravity Vee Diverter, materials can flow toward either outlet individually, both outlets simultaneously, or both closed for material shut-off. Features: * Dual cylinder gate design. * Diverter body, blade & material contact areas constructed from 316L stainless steel. * Seals constructed from PET polymer, for food-grade product safety. * 24 in | 610 mm round inlet transition, to connect with a hopper above. Inlet transition * features 12 fluidizer pads to assist material flow. * Round, 12 in | 305 mm, ANSI flange outlet transitions, to match the client’s pre-existing footprint. * Pre-wired terminal box. Set up for a Class II, Div I (Groups E, F, G) environment. This dual cylinder Gravity Vee Diverter was

Vortex Seal Tite Diverter Handles Pet Food Kibbles
Vortex Seal Tite Diverter Handles Pet Food Kibbles
A pet food manufacturer needed to divert kibble dry food from a feeder into one of two disc conveyors, which transports the kibbles to the packaging line. Vortex engineered several 254mm Seal Tite Diverters constructed from stainless steel for the pet food company. The four Vortex Seal Tite Diverters feature a removable access door that allows inspection, maintenance and repairs to be performed without removing the diverter from service. The Seal Tite Diverters also feature removable parts. For return-on-investment purposes, this feature is beneficial because it allows for the replacement of worn parts, rather than full diverter replacement. The Seal Tite Diverters are designed so that the leading edge of the blade actuates into a recessed area. This protects the blade’s seals from the material flow stream, which would otherwise cause them to wear and allow material leakage into the closed diverter leg. The client is very pleased with the performance
