Systems & Equipment

Milmeq custom designs, engineers and manufactures equipment for primary food processing operations, providing the complete solution to take the product from hot to cold.

Use the below filters to filter our systems and equipment by system category and industry.

Chilling and Freezing

Milmeq custom designs systems for any type of food processing operation requiring chilling, freezing or thawing of product.

In the 1980’s Milmeq pioneered the introduction of large scale plate freezing technology to the meat industry, along with air-blast chilling and freezing tunnels. Today our plate freezers and single and multiple retention tunnels (SRT and MRT) are recognised as setting the global standard for optimising operating efficiencies and product quality.

With the key goals of increasing shelf life, prevention of weight loss, maintenance of product quality and ensuring consistency of product for the consumer, we have developed a range of chilling and freezing technologies. Our systems are configured to provide a hands-free environment in order to improve operator safety, reduce handling and retention time, increase product throughputs and enhance inventory management.

Our chilling and freezing expertise also includes carcass spray-chilling systems for beef, sheep and deer and complete refrigeration engine room design and air conditioning of process environments.

Tunnels (SRT and MRT)

Chilling and freezing tunnels are another innovation that was pioneered by Milmeq in the 1970s. Today we supply custom-designed automatic tunnels to the meat, poultry, dairy, seafood and horticulture industries.

Tunnels employ an air blast based system that provides uniformed conditioning to either chill or freeze product. Application of very low temperatures in a controlled environment enables a fast chill or freeze; typical cycle times range from two to 48 hours.

Interfacing conveyor systems provide completely automatic, hands-free loading and unloading of product, precisely timed to achieve the desired temperature. Eliminating manual handling preserves product quality and reduces the incidence of injury through strain.

The integrated controls and automation designed for each system application allows for operator changes to the set retention time. The controls also deliver complete tracking of all product within the system which aids in the management of further processes post-chilling or freezing such as palletising and distribution.

Tunnels can be designed to operate with a variety of refrigerants depending on customer specifications and desired cycle times, in order to integrate with other process flows within the facility.

Our tunnels come in two distinct designs; the single retention tunnel (SRT) and multiple retention tunnel (MRT). Follow the links below to learn more about each of these.

Tunnels (SRT and MRT)

Single Retention Tunnel (SRT)

The Single Retention Tunnel (SRT) is designed to accommodate varying product types and carton sizes that all require the same chill or freeze time.

The SRT can be designed to be either a chill or freeze tunnel. The single retention time, the enclosure temperature and air velocity will be calculated depending on the temperature of product entering the system and the desired temperature for exit.

The SRT is a first in, first out system which means all cartons complete a full rotation within the system. The carton in feed and out feed conveyors are therefore positioned at one end. These interfacing materials handling systems can feature multiple levels to decrease the load and unload times.

The SRT is suited to food processing operations where there is a high throughput of products that require the same conditioning and follow on to bulk distribution loads.

For example, our tunnel has a unique application for the block cheese industry. Collaboration with the industry on the newly adopted hot formed cheese block tower making process resulted in the development of the Realcold Rapid Chiller during the 1970s. This unique cheese cooling tunnel provides a true 24 hour cooling cycle for block cheese that ensures product quality, colour and flavour are maintained. We continue to provide this variation of the SRT to the dairy industry today.

Tunnels (SRT and MRT)

Multiple Retention Tunnel (MRT)

The Multiple Retention Tunnel (MRT) is designed to accommodate varying product types and carton sizes that require different chill or freeze times.

It is a completely automatic air blast based system that provides flexibility to apply different cooling regimes for different groups of product.

Shelves within the system are allocated different retention times and the interfacing conveyors pre-sort and accumulate product types allowing transfer onto a designated shelf depending on whether the product requires chilling or freezing.

The shelves move at different paces and the in-feed and out-feed carton conveyor transfers are typically placed at either end of the tunnel.

The MRT is suited to food processing operations where there are a number of lower throughput products that each require different conditioning and follow on to customised distribution loads.
