Keys to smooth operation – listening and planning

A big part of ensuring the smooth operation of a new project is clear communication between client and provider. Aurora receives excellent reviews from its clients who say they listen to client needs and maintain regular contact throughout the project and post-installation.
 
Geoff Hadwin, general manager at Cresta Mushrooms has first-hand experience as Aurora supplied and installed a metal detector for their production plant.
“Aurora listened to what we wanted and sourced the machine we needed. They then programmed it to what we wanted and installed it,” says Geoff.
“It was a complicated thing they were having to do, but they were good, and they were always very pleasant to deal with. And once the machine arrived their communication level was great.”
 
Every load of mushrooms now goes through the new metal detector to ensure no metal contaminant is passed on to the consumer, and its main benefit is that it saves a lot of product.
Cresta Mushrooms didn’t consider going with any other supplier when Aurora was recommended to them, and Aurora delivered on their high expectations.
 
“We were happy with their product, price and service, and with their performance,” says Geoff.

Traffic management is critical

Traffic management involves a systemised approach to analysing and controlling the traffic movements in and around a production or warehousing facility. Every facility should have comprehensive traffic management plan.
When you have trucks, fork lifts and other heavy machinery on site it will inevitably create the hazard of mixed traffic. This needs to be isolated, controlled or eliminated to ensure people’s safety at work.
 
Pedestrian traffic must be managed wherever there are vehicle movements in a work place – it only takes a single moment of inattention for a serious or even fatal accident to occur.
Designated pedestrian walkways, using the certified Tru-Gard barrier system, are an effective solution to ensure employees and visitors don’t stray into danger zones.
 
Doorways to warehouses, factories and loading bays are also areas that can be overlooked when it comes to safe traffic management. Ideally doorways should not have mixed traffic types and it is recommended that traffic flow is restricted to one direction.
Implementing traffic management systems not only reduces the health and safety risks on your site but it can also help with streamlining your entire production or warehousing facility. Standardisation across multiple sites also reduces the risks associated when employees move between sites.
 
Talk to us today about how we can help you reduce the health and safety risks that you are faced with in your workplace.

Digital valve controllers

Emerson Process Management has introduced the Fisher Fieldvue DVC6200p series of digital valve controllers.
The DVC6200p series is an ideal solution for applications in which accessibility, extreme temperatures (up to 120°C/250°F), extreme vibration or confined space make integral mounting difficult or impractical.
 
Industries such as pulp and paper, and metal and mining have typically preferred to isolate valve-mounted instruments from harsh environments. With the remote mount version of DVC6200p, only the valve position feedback is mounted on the control valve, while the remainder of the digital valve controller can be mounted more than 90m away in a less severe or more accessible environment.
The remote valve mounted feedback unit uses the patented Fieldvue linkage-less, non-contact feedback technology in which physical contact has been eliminated between the valve stem and the instrument. With no linkage to wear, loosen, corrode or vibrate, the feedback unit can withstand a plant’s operating extremes.
 
With over one and half million units installed worldwide, Fieldvue digital valve controllers prove highly suited to difficult process environments where they provide unmatched valve operation. 
Using the best of Profibus PA, the DVC6200p series provides a wealth of alerts, trends, and diagnostics to allow for visibility and control, The DVC6200p supports enhanced device description (EDD) files that allow for quick and easy configuration.
The Fieldvue DVC6200p digital valve controller is certified to Profile 3.02 for Profibus PA devices by the PROFIBUS Nutzerorganisation a.V (PNO).
 
The DVC6200p is offered with CSA, IECEx, ATEX and FM hazardous area approvals as well as other certifications/approvals. It is also listed in the Lloyd’s Register for industrial, marine and offshore use.

Milk cooling crucial for export dairy industry

With standards for milk and milk products becoming more stringent, business owners and farmers need quality cooling options to keep up the important dairy industry’s contribution to the Australian and New Zealand economies.
The dairy industry’s customers, for example those in the Asia/Pacific region, are demanding 100 per cent assurance of the milk quality from the moment it leaves the cow to when the end-user purchases the product. That means strong control over the quality of the milk as it is being taken from the cow, then onto the on-farm storage, pick-up and transportation to the processing plant phases.
 
When milk is taken from the cow, its temperature is 35 degrees. The longer it remains above 4’C, the greater the bacterial growth and the more unsafe it becomes to process. The timing to cool the milk below 4’C is critical to the quality of the product, and after a very short time it actually becomes worthless.
 
According to the Australian Department of Agriculture, Fisheries and Forestry, milk must be cooled within two hours of milking at no more than six to eight degrees depending on collection date. The temperature control system must maintain the temperatures to no more than 10 degrees during transport.
This highlights why the milk cooling system needs to be correctly sized and selected in the first place and then checked and serviced at regular intervals. One of the key components of this is making sure the plate heat exchanger can maintain the heat load efficiently and effectively at the correct temperature.
 
Milk coolers should be chilling the milk to within 2 degrees of their cooling water supply temperature or you are just throwing money into energy bills. The cooler the milk enters the vat storage, the cheaper it is to keep cool and the better the quality of the milk.
If the plate heat exchanger isn’t working properly, either it is sized incorrectly, or your herd has increased in numbers and thus the cooling duty has changed, or simply the milk cooler has become fouled with various contaminants that will cause a reduction in flow and/or inefficient cooling. The cooling system will then need to work much harder to cool the milk, again hurting the farmer in energy costs, and finally the milk quality will, not might, be compromised simply from not being chilled and stored cold enough.
Dairy farmers would be advised to get a dual bank exchanger that Sondex can provide. And remember “the taller the plate the cooler the milk” - the old adage of just add more plates is long dead and gone, science clearly shows that the longer the thermal length of the heat transfer plate the longer the resonance time in contact with milk, this is what will give you virtually instant cooling of the milk together with chilling it down to the required storage temperature while reducing your energy bills.
Sondex can also assist in designing and creating specific heat transfer equipment that can cover all the producer and processor’s milk cooling/heating needs.
 
The penalties for non-compliance can be quite large for businesses across regional Australia and New Zealand. If the milk is found to be not at the required temperature or have high bacteria counts, individuals are advised to correct the fault. If after this warning the problem is not fixed, there can be serious consequences - such as excluding the producer’s milk products from supply and removal of declaration of compliance.
 
This industry is full of fine margins, which is why it is so important to have your heat transfer system in top shape. If you are unable to pinpoint the faults in the heat exchanger it may pay to contact Sondex who can also offer professional technical advice.

Push together water pipes that can take the strain

As New Zealand’s leading producer of quality frozen convenience foods, Leader Products have been experiencing ever increasing demand from their customers.  This demand has been driven by increased sales of their existing products, as well as the development and introduction of new ones. This has put strains on their current production capacity.  To meet this growth, they 
have been adding new equipment to their plant in Otahuhu in Auckland.
 
Most recently, they installed a new Retort Pressure Cooker.  The unit need a water supply connected to it.  The water supply would be taken from an existing galvanised steel line in the roof cavity above the processing factory.  
Using a pipe system that could be installed without welding and the need for hot work permits was important for Leader, as the walls and roof are made of flammable polystyrene sandwich panels, typical in food processing plants.  Access in the roof cavity was very confined in places, adding further challenges to the installation.  
 
Leader Products selected Kembla’s KemPress stainless steel piping system for the extension.  Being made of 316L stainless steel, it met food their food safety requirements. The weld-free press fit jointing system eliminated both the fire risk around their polystyrene sandwich panels, as well as the time and need to complete the hot work permits.  The range of KemPress Stainless fittings, including the BSP threaded unions, made it simple to connect the Kempress piping system to the existing galvanised steel water line via a ball valve.  The Kempress Stainless system’s compliance with standards AS 5200.053 and AS3688 gave Leader the peace of mind that the system was reliable and robust.
 
Leader Products own engineering team undertook the installation of the KemPress piping system.  The actual pipe installation took less than a day, and it was completed with no leaks.  Leader’s Engineering Manager, Richard Crabb noted that this helped them recover some lost time on the installation due to other issues that can often occur when commissioning new plant equipment, ensuring they met their production start deadline.
 
Leader Products engineering team found the KemPress piping system easy and quick to install, with Richard Crabb commenting that “we will use the product again as we continue to add to our plant capacity”.
As demonstrated at Leader Products, Kembla’s KemPress stainless steel press fit piping system has proved itself numerous times to be a quick and easy system to install, yet still being an extremely robust and reliable system.  Especially for use in food and beverage processing where plant operation time is critical to meet customer demands.

“Shipping Containers - Gas Hazards!

Any engineering operation that imports goods in shipping containers faces an unexpected risk – toxic gases inside the container. A study by NZ Customs showed that about 1 in 5 import containers could be at risk. The types of gases found include neurotoxins like Methyl Bromide from fumigations, but also carcinogens like Formaldehyde from wood products. Even machinery parts from overseas, can emit benzene and other cancer causing hydrocarbons, from oils and chemical coatings. In many cases, gases can accumulate to dangerous concentrations, without being able to be detected by human smell.
Fortunately there is a solution available – gas detection and ventilation equipment. This is widely used by Customs authorities in New Zealand, Australia, Canada and Europe, but so far the problem is not widely recognised by private industry. A hollow stainless steel probe can easily be inserted through the container door seal, before it is opened, and the gas levels checked with a monitor. If unsafe levels are found, the container can be ventilated fast and efficiently, using a patented system available from Nordiko Quarantine Systems Pty Ltd.
