Case Studies

Central Transport – innovation by the truckload

The Brief

New Zealand dairy company, Miraka, needed to collect and transport large volumes of milk safely and efficiently from farm to factory – for processing at their state-of-the-art facility at Mokai, Central North Island.

The Issue

Transport is not Miraka’s core business, so transport and logistics company, Central Transport Ltd (CTL) was contracted to manage the logistics of efficiently collecting and transporting this valuable commodity from 104 local farms. This required specialised equipment to collect milk from farms, transport and deliver it safely, while complying with stringent food safety requirements.

The Solution

Tīra NDA worked collaboratively with the CTL team to develop and deliver milk transport truck and trailer units specific to their needs to meet the high standards demanded by Miraka.

Our design included innovative features such as the drop belly, centre draining trailer unit, which allows for lower COG and enhances trailer performance and safety. The truck units were equipped with the latest technology in milk metering and sampling systems, ensuring full traceability of product from farm to factory.

Fonterra New Zealand – transport that performs all the way

The Brief

As New Zealand’s largest milk supplier, Fonterra have an ongoing requirement for safe, efficient transportation of milk from farm to factory, or between their various processing plants.

The Issues

Fonterra’s requirements are very specific; an immense amount of valuable milk has to travel for long distances on rural roads, so its transportation units need to be up to the task.

The Solution

Over the years, NDA has worked collaboratively with Fonterra to develop a design for its milk transport units that meet its particular needs. We’ve developed innovative features such as the ‘drop belly’ and the centre-draining trailer unit, which allows for lower COG and enhances trailer performance and safety.

A very big cheese – innovation for the US market

The Brief

NDA was engaged by IDS to manufacture an eight-tonne-per-hour CheddarMaster™ cheese machine for delivery to Mullins Cheese in Mosinee, Wisconsin, USA.

The Issues

Fully assembled, the CheddarMaster™ machine was nearly 40 metres long, 6.2 metres wide and nearly 9 metres at its highest point, requiring fabrication and transport in three separate sections and final assembly on site. The machine needed to be manufactured to meet stringent USDA requirements.

The Solution

Tīra NDA worked closely with the IDS design team to develop practical, innovative and efficient fabrication details as part of the manufacturing methodology. Tīra NDA’s significant workshop capacity and resources meant the machine could be fabricated in separate sections and pre-assembled in the workshop – before dismantling and packaging for shipping to the USA. Attention to detail and our excellent quality systems ensured we could meet all requirements of the USDA quality standards.
