Design of carcass chilling facilities - with optimal meat quality output

Designing carcass chilling facilities for optimal meat quality output is our specialty at DMRI

We bring our unique expertise to the table, whether you're embarking on a new chilling process or enhancing an existing one. Our chilling processes are meticulously crafted to achieve a chill loss of 0.7% to 1.3%, tailored to your specific requirements, whether you opt for a hard or soft process. Moreover, we stand by our commitment with a chill loss guarantee.

Constructing or upgrading chilling facilities demands precise equipment sizing and design to ensure the right process parameters. Drawing from our extensive experience, we excel in extracting heat from hot carcasses efficiently, mitigating potential design flaws, and optimizing project expenditures without compromising on quality.

Engaging DMRI for your project means accessing proven technical specifications validated by our own engineers' field expertise. We'll guide you through contractor and supplier selection, ensuring adherence to our rigorous process standards.


Upon project completion, DMRI conducts thorough performance testing to identify any necessary contractor adjustments. From inception to conclusion, we're with you every step of the way:


DMRI's designs deliver:

  • Enhanced meat quality
  • Minimal chill loss (evaporative loss during chilling)
  • Reduced drip loss (meat juice in packaging)
  • Lower operating costs
  • Ample chilling capacity
  • Precise final product temperatures
  • Minimal building condensation (no dripping)
  • Structural durability

Quick Chill Tunnel DMRI



















Value of chill loss

The water that evaporates from the skin and meat of the carcasses poses a significant loss in yields. Analysis of sales numbers from various pork slaughter facilities determined the average value of 1% of chill loss to be approx. 1.3 EUR per carcass.

In one case, one of our customers running 700 pigs/hour in a two shift operation was able to increase yearly sales of approx. 3,500,000 EUR by reducing their chill loss with 1% by refurbishing their chilling process using DMRI’s specifications.
