Klar madvarer holder deres kølige takket være viskøs opløsning fra HRS

THECOO ~ 2

Ready Foods, en amerikansk producent af supper og saucer, har reduceret den tid det tager at afkøle en af ​​sine kerneprodukter med en tredjedel takket være et nøglefærdigt kølesystem fra HRS Heat Exchangers. HRS-opløsningen, der er ideel til viskøse materialer, har gjort det muligt for Ready Foods at øge produktionen af ​​den kødmarinade, den leverer til en førende restaurantkæde, markant.

Based in Denver, Colorado, Ready Foods is a cook and chill company which manufactures soups and sauces for restaurants and the meat industry. After receiving a large order for one of its meat marinades from a leading chain of quick-service Mexican restaurants, the company needed to increase capacity. The existing process of kettle cooking and steaming the marinade, then chilling it in 5lb pouches in a water cooling system for three hours, would not allow Ready Foods to meet the customer’s increased demand for 2,000lb totes. So, Marco Antonio Abarca, President and Owner of Ready Foods, and Greg Hefter, Plant Engineer, set out to find an alternative solution that would enable them to decrease the length of time it took to cool the marinade from 200°F to 38°F and thereby increase production levels.

En simpel løsning

However, they soon discovered that finding the right cooling system was no easy task, Greg commented; “Some recommended systems which required a large footprint or a 20ft ceiling height; others could only supply one or two parts of the solution and expected us to source the rest and integrate it ourselves; while some showed us systems which were far too complex and sophisticated for our operatives to use,” adds Greg. “We don’t have the luxury of a team of engineers on call 24/7, so any system we chose had to be simple to operate and straightforward enough for our mechanics to take care of.”

fleksibelt design
Only one supplier, HRS Heat Exchangers, was able to meet every one of Ready Foods’ requirements, so Marco and Greg sent them two versions of their marinade for testing. One was very thin while the other was a concentrated form of the product.

“At first, Ready Foods proposed cooling the thinner product using R-404 refrigerant,” says Cameron Creech, HRS’ US Sales & Engineering Manager. “As that’s an aggressive cooling media, we considered a two-stage cooling system: the first phase would cool the product with chilled water, a much-less aggressive medium; the second stage would involve chilling with ammonia.”

The original purchase order for this solution was issued in July 2017 but shortly after, Ready Foods’ client changed the brief, opting instead for the thicker product and choosing glycol rather than R-404 refrigerant as the cooling medium. HRS quickly put together a revised design and the new PO was approved in September 2017.

Samlet støtte

HRS’ turnkey solution for Ready Foods comprises a transfer pump to move the product from the cook kettles into the balance tank; a balance tank to receive and mix both recycled and new incoming product; a BP-6 hydraulic pump to push product through the system; a pre-cooler, consisting of 10 AS Series triple-tubes as the pre-cooling exchanger, which cools the product using chilled water; the final cooler, comprising two Unicus scraped surface heat exchangers; and finally, a three-way valve which sends product into the filler tank or back to the balance tank, depending on whether the temperature requirement is met or the filler tank is too full to receive product.

Hygiejnisk drift
HRS leverede også ekstraudstyr, inklusive et CIP-system (Clean-In-place) og et dampdrevet varmtvandsanlæg for at forhindre frysning i tilfælde af produktionsstop (bruges også til at opvarme opløsningen under det automatiserede CIP-program).

Indstilling af standarden
The cooling system was commissioned in September 2018 and has been operating successfully ever since. The difference in the volume of product Ready Foods is now able to produce is considerable. “It used to take us three hours to chill the marinade, but we are now able to cool it in just one hour. We’ve been able to keep up with our client’s new, increased demand, even at peak times. On a five-day-a-week basis, we can hit 200,000lbs,” concludes Marco.

From an operational standpoint, it’s proved itself to be an integrated system which is not too complex and boasts a small footprint. In addition, due to the fact that a large percentage of Ready Foods’ employees are Spanish-speaking, HRS incorporated a feature on the main page of the program which allows the controls to be switched between English and Spanish.
