“They also suggested some good value

engineering solutions that helped the return on the project, which was installed on time and on budget.” Advance’s sales & marketing manager,

A conveyor system solution from Advance Automated Systems has streamlined product flow and improved Health & Safety by reducing forklift truck traffic at an aqua feed manufacturer


dvance Automated Systems has recently worked with Cargill, one of

the largest global suppliers of aqua feed, to provide a conveying solution at their Westfield site in Scotland. Cargill’s aqua feeds are supplied to

salmon farmers in Scotland and around the world. In the supply chain, feed is bagged into bags on pallets and bulk bags with a single lift point. Bags are 500kg, 1000kg and 1250kg, with all having the same footprint. The process of moving bulk bags around

the site incorporated multiple lifts and handling, together with excessive forklift traffic collecting from the dispensing hoppers. Associated issues included inefficient handling of the product, as well as the potential for a higher risk of accidents with forklift trucks operating in the production area around operators. Advance presented a fully costed proposal that resolved the current

operational issues of multiple handling and the concentration of forklift truck traffic. The solution involves the installation of a section of modular belt on an automated shuttle that will simply travel along guide rails stopping at multiple out-feed points to feed the bulk bag onto one of several accumulation lanes. With a conveyor system consisting of

Intralox modular belting, Lenze SMART motors, Siemens S7 PLC for system logic and a Siemens KTP700 touch screen HMI for system control and feedback, the solution was manufactured, programmed and installed by Advance engineers. Following installation, Atholl Cameron,

maintenance & projects manager, said: “The big bag conveying project is part of our ongoing capital plan to streamline flows and improve H&S by reducing traffic movements. We approached various companies to look at the project, but Advance were the only company to


A new sanitary Munson Rotary Batch Mixer model 700-TH-40-SS with internal spray line is said to distribute liquid additions throughout dry solids in one to three minutes with total uniformity and minimal shear or heat. The spray line can introduce coatings, flavourings, vitamins or active

ingredients in liquid form into any bulk solid food, nutraceutical, chemical or mineral product. Proprietary mixing flights within the rotating drum fold, tumble,

cut and turn the material, which recombines 288 times per minute and creates a wide bed of moving material onto which liquids can be sprayed in trace amounts or large quantities for rapid incorporation. The flights also direct the material toward and through a stationary, pneumatically-actuated plug gate valve for total discharge, eliminating residue that would otherwise be wasted or require manual removal prior to cleaning. Twin doors on opposing sides of the mixing vessel and a sliding intake chute

provide unobstructed access to the interior, intake spout and seal area for cleaning, sanitising and visual inspection of all material contact surfaces. An internal supply line allows in-place rinsing and cleaning. Constructed of stainless steel finished to sanitary standards, the mixer has a useable batch capacity of 1,130l, total capacity of 2,320l and is equally effective in blending of batches from 100 per cent of rated capacity to as low as 15 per cent without liquid additions, and to 33 per cent with liquid additions.

This project has showed the ability of Advance to use standard core product alongside bespoke equipment

Shaun Graham, said: “The main technology behind the conveyor system is very similar to our Advance SmartLine Pallet Conveyor System, however, as the product was not suitable for being transported on a traditional roller conveyor we adapted our designs to use a modular belt conveyor for the product zone. In addition, each zone is driven via its own Lenze SMART motor and is only running as and when it is needed, making the whole system very energy efficient.”

A new JET-FEED Garnet Delivery System from Flexicon automatically feeds garnet directly from bulk bags to waterjet cutters, eliminating worker fatigue, potential injury, labour, spillage, dust, downtime and higher material cost associated with manual dumping of bags typically weighing 25 to 50 kg. A BFF Series BULK-OUT bulk bag

discharger allows floor level connection of bag straps to a lifting frame, which is forklifted onto cradles of spring-loaded POP-TOP extension posts. Weight of the full bag compresses the posts, which stretch the bag upwards when it empties/lightens to promote flow. The bag outlet spout is pulled through an iris valve which is then closed, preventing material flow while the spout is untied and the access door is closed. The discharger employs FLOW- FLEXER bag activators that raise and lower opposite bottom sides of the bag at timed intervals, loosening compacted garnet and promoting flow into the bag discharge spout. The floor hopper charges a Flexicon flexible screw conveyor, which can be routed vertically, horizontally or any angle, over short or long distances, to the waterjet pressure pot location. The only moving part contacting

garnet is a rotating screw that self- centres within the abrasion-resistant polymer tube, preventing garnet from grinding between the screw and tube wall. The screw is driven beyond the point at which garnet exits the conveyor, preventing contact with seals. Flexicon PROCESS & CONTROL | SEPTEMBER 2019 39
