Cartons of meat are closed, frozen, sorted, tracked, stored, retrieved, palletised, wrapped and labelled by machines, all with minimal human intervention.
MHM General Manager Sales & Marketing, Tony Johnson, said the solution set a new standard for the meat processing industry in Australia.
“This kind of process automation provides the answer to a range of challenges that processing plants are grappling with right now – from labour shortages to the need to reduce their carbon emissions,” he said.
The custom-designed system was the result of intensive engagement and consultation with Midfield Group.
Midfield Group’s objectives for the upgrade included freeing up space for further processing expansion, reducing its reliance on manpower, having the ability to effectively manage inventory for production and sales, and reducing its overall energy consumption.
After intensive engagement and consultation with Midfield, MHM Automation proposed a custom-designed solution comprising a six-mag lidder, four SSO plate freezer stacks, two automated storage and retrieval systems (ASRS) and a three-cell robotic palletising system.
The project was delivered in stages over three years, culminating in the commissioning of the ASRS in June 2023.
ASRS – a game changer
Delivered by MHM in collaboration with its European technology partners TGW and Inther, the ASRS automatically sorts incoming cartons from the production line by SKU. It then transfers and stores them in a space-efficient racking system and retrieves them on demand to assemble rainbow pallets to fulfil individual customer orders.
Two ASRS systems were installed at Midfield, one for chilled and one for frozen meat products.
Johnson described the ASRS as a game changer for the food processing industry.
“With the ability to deal with a high volume of products in constant motion, the ASRS streamlines the movement of goods in and out of storage effectively and efficiently. It is ideal for plants producing large numbers of SKUs and needing to combine those products into custom pallets to meet customer requirements,” he said.
The ASRS offers a host of benefits, encompassing comprehensive inventory management and seamless integration with production and sales management systems. Its high-speed elevators and live shuttle system enable efficient order picking. Notably, it eradicates manual handling concerns and ensures impeccable traceability.
Whilst ASRS systems are commonly used in warehouses to handle pallets or cartons of dry goods, MHM’s system is relatively unique in its ability to operate in chilled and frozen environments.
“This makes the technology ideal for food processors,” Johnson said.
Integrated solution benefits
Other equipment in the system also delivered important improvements to Midfield’s operations.
The installation of the lidder and plate freezers in 2021 amplified the plant’s freezing capacity to approximately 25,000 cartons per day.
Well recognised by the Australian meat industry as the preferred freezing system to meet stringent export food safety requirements due to its 24-hour freeze time, MHM’s plate freezers also deliver significant energy savings of up to 30% compared to blast freezing. Contact freezing between plates ensures the frozen cartons are completely flat, which was important to enable integration with the ASRS and automated palletising system at Midfield.
Added in 2022, the palletising system alleviated labour requirements, which were proving difficult to fulfil in a stretched labour market. It mitigated health and safety hazards associated with manual handling of heavy meat cartons, and also introduced automation to pallet scanning and Meat Messaging label generation, eliminating the need for manual port marking.
A trusted partnership
The integration of advanced technologies has not only elevated Midfield’s operational efficiency but has also ushered in a new era of enhanced capabilities.
Midfield Group CEO, Dean McKenna said the project’s success was the result of a trusted partnership.
“At Midfield Group we are committed to providing superior products and reducing our environmental footprint. We strive to be ahead of the curve when it comes to introducing new technologies that help us achieve those goals.
MHM Automation understands our goals and works with us to achieve them. We particularly value their ability to provide an integrated, end-to-end solution. They have delivered everything they promised, and more,” he said.

The field of food technology is constantly developing to find more sustainable and effective ways to produce, distribute, and consume food. The following are some encouraging developments in this area:
Protein Agriculture
Animal protein production significantly impacts greenhouse gas emissions worldwide. As a result, companies creating substitutes, primarily plant-based and, more recently, via cellular and molecular agriculture, are now competing. Cellular agriculture uses cultivated cells to produce animal tissues, proteins, and lipids. Conversely, molecular farming uses plant molecules as "mini dairy farms" to grow and duplicate animal proteins through photosynthesis.
Protein Fermentation
Protein fermentation is an inventive technique for obtaining animal proteins. There are two varieties of this process: biomass fermentation and precision fermentation. Precision fermentation uses genetically engineered organisms to produce dairy proteins, enzymes, lipids, and vitamins. In contrast, biomass fermentation uses fungus, yeast, or bacteria to create foods high in protein from organic material quickly. The manufacture of chymosin for parmesan cheese is one example.
Food as Medicine
Using food's therapeutic and nutritional qualities to support and restore health is a long-standing custom. But thanks to technological advancements, the idea of food as medicine has changed and taken on a more profound significance. Functional foods offer health advantages beyond their nutritional content, and nutraceuticals—which are made from food ingredients—may be able to treat illnesses. For instance, probiotic yogurt, cod liver oil, and milk with vitamin D added are examples.
3D-Printed Food
3D-printed food is a potential development that would allow users to create customized meals with particular forms, colors, realistic textures, and mouthfeel sensations. This technology would benefit the plant-based market and populations like those with autism, ARFID, or the elderly who might have sensory sensitivity issues, dysphagia, or other food-related disorders.
Designer Crops
Traditional agriculture is under stress from the growing global population, climate change, and unsustainable farming methods, which results in food shortages, spoiling, malnutrition, and insecurity. Designer crops provide increased resistance, yields, and nutrition through sophisticated breeding and gene editing. Pest-resistant bananas, reduced-cyanide cassava, and vitamin-enriched rice are more robust and nutrient-dense food sources.
Digital Supply Chain
Issues with accessibility, emissions, waste, and contamination plague today's food supply chain. Technologies like IoT, AI, blockchain, and automation make food tracking from farm to table, conditions monitoring during transportation, and data analytics for optimization possible. This digital revolution will result in a more intelligent, transparent, sustainable, and efficient food supply system.

Food waste is a global challenge with severe economic, environmental, and social repercussions. Simultaneously, demand for sustainable, eco-friendly packaging is escalating. Smart temperature-sensitive packaging emerges as a powerful solution, marrying these two critical needs by significantly enhancing food freshness, extending shelf life, and becoming an integral part of modern waste reduction strategies.
Intelligent Packaging: A Temperature-Responsive Solution
Smart temperature-sensitive packaging, often classified under Intelligent Packaging, integrates active components that visually or electronically indicate a product’s temperature history. This innovation marks a paradigm shift from traditional time-based “use-by” dates to condition-based “best-before” indicators that better reflect food quality. Among the leading technologies driving this transformation are Time-Temperature Indicators (TTIs), RFID tags with temperature sensors, and temperature-sensitive inks or polymers. TTIs use labels or inks that irreversibly change color or shape upon exposure to specific temperature thresholds, offering consumers clear visual cues of temperature abuse and providing a more reliable reflection of product freshness. RFID tags, on the other hand, embed chips within packaging to continuously log and transmit temperature data throughout the supply chain, enabling manufacturers to trace and isolate compromised batches, thereby enhancing quality control and cold chain integrity. Temperature-sensitive polymers or inks act as built-in quality checkpoints, activating only when a temperature violation occurs, ensuring that products meet storage standards at every stage of distribution.
Bridging Freshness and Sustainability
The integration of intelligent packaging systems brings significant value to both food preservation and sustainability goals. By monitoring the thermal history of products, technologies such as TTIs and sensors allow for more accurate shelf-life assessment, effectively extending the safe consumption period for perishable goods like meat, dairy, and produce. This monitoring reduces premature disposal and helps consumers make informed decisions about product freshness.
Intelligent packaging also supports targeted waste-reduction strategies—allowing businesses to triage and reprice items with mild temperature deviations rather than discarding entire batches —while sensor data enables data-driven improvements in logistics and cold chain management. Significantly, the industry’s commitment to sustainability extends to the materials themselves. Ongoing research focuses on developing biodegradable and compostable TTIs, as well as printed electronic sensors on paper or bioplastic substrates. These innovations ensure that technological progress in food preservation aligns with circular economy principles—addressing food waste without contributing to plastic pollution.
For smart temperature-sensitive packaging to achieve its full potential, standardization, cost reduction, and consumer education are key. As the technology matures and becomes more cost-effective, its integration from farm to fork will create a transparent, accountable, and highly efficient food supply chain.
Ultimately, these intelligent packaging technologies are more than just labels; they are data-rich tools that empower consumers, retailers, and supply chain managers to make informed decisions, transforming an uncertain "use-by" date into a verified guarantee of freshness, thus taking a massive bite out of global food waste.
