Projects

We have delivered primary food processing, materials handling and chilling and freezing technology to clients around the globe.

The following are some of our recent projects.

VRIESCENTRALE ASTEN – ASTEN, NETHERLANDS

Single Retention Freezing Tunnel

The Client

Vriescentrale Asten is a contract cool store operator which sorts, packages and freezes pork and beef products for export.


The Challenge

To expand their operations and expand their export markets, Vriescentrale Asten required improved freezing facilities. Their existing blast freezers took several days to freeze product and no longer had sufficient capacity to freeze everything being processed on-site.

Their primary objective was to achieve a faster freezing time in order to improve shelf life, enable adherence to the highest food safety standards and enhance operating efficiencies.

Energy efficiency and the use of environmentally friendly refrigerants were also key considerations.

One of the challenges was that the freezing equipment needed to fit within a small footprint available inside the existing factory.

They approached Milmeq’s European agent, Cofely Refrigeration to provide a solution.

VRIESCENTRALE ASTEN – ASTEN, NETHERLANDS

Single Retention Freezing Tunnel

Our Solution

Milmeq custom-designed and manufactured a single retention freezing tunnel (SRT) to meet Vriescentrale Asten’s needs.

The tunnel operates at minus 45°C to shock freeze meat products to a core temperature of minus 25°C in just 18 hours. Having cartons loaded on shelves means consistent conditions are applied to all cartons, which retains product quality. Automatic loading via the conveyor system eliminates the need for manual handling.


The tunnel has given Vriescentrale Asten a freezing capacity of 160 tonnes per day.

The tunnel’s refrigeration system is powered by natural refrigerants carbon dioxide (CO2) and ammonia (NH3). To keep the levels of NH3 to a minimum, a cascade system is used where CO2 is applied to freeze the product.

Cameras were installed to provide remote monitoring of the tunnel. These were particularly useful during the commissioning stage, and allow ongoing contact with Milmeq for speedy diagnosis and resolution of issues at any stage.

The Result

The installation of the tunnel and resulting fast freezing of meat has enabled Vriescentrale Asten to achieve NL 514 EG and NL 5694 EG certifications for food safety, which have facilitated their entry into new export markets.

Power consumption for freezing has reduced by 35%, compared with using the blast freezer.

This combination of sales growth and savings in operating costs saw Vriescentrale Asten achieve payback for their investment in the tunnel in less than two years, which was half the time they had budgeted for.

“Installing a Milmeq tunnel was the best decision our business ever made. It has been the catalyst for growth in our company, enabling us increase the quality and quantity of product we produce.”
