COOLING THE NEW STANDARD

The PROPlateHX is a stainless steel, gasketed, plate and frame heat exchanger used to remove and add heat as the process requires.

PRO + THERMALINE 

A PARTNERSHIP DEDICATED TO COOLING MILK

THE PARTNERSHIP

In the early 1990’s, a group that included PRO Refrigeration, Thermaline, and Babson Brothers Company worked together to introduce a new concept that we called Instant Milk Cooling, which unquestionably changed the game of cooling milk.

At the time, there was essentially one way to cool raw milk, using a refrigerated bulk milk tank. Larger farms used well water to precool the milk, but at the center of every dairy farm’s cold chain was a refrigerated bulk tank.

As dairy production grew and standards tightened, conventional cooling methods simply could not get the job done.

Initially, Pro and Thermaline worked directly with some of the largest farms in the Pacific Northwest (farm names like Smith Bro’s, DeRuyter, and Krainick Farms). These farms had increased production and simply outgrown the capacity of their cooling systems. It was exciting testing, designing, and installing systems; there were never two built alike, but each was a step closer to a new way to cool milk, instantly.

Today Pro partners with a network of the highest skilled dairy builders and equipment dealers across North America. These dealers understand the challenges and expectations of today’s farmers better than anyone, and they play a key role in the development of our products.

INSTANT COOLING

At the center of Instant Milk Cooling is a 2-Stage Thermaline Plate Heat Exchanger matched with a PROChiller System. The first chiller and plate cooler combination designed specifically to cool milk from 98°F down to 36°F as it is being transferred from the parlor to the milk house.

By adding a properly sized DAIRYPro Vat, the concept of Instant Milk Cooling has transitioned into the industry standard, and today applied to every new production dairy built in the United States.

In addition to producing higher quality milk, Instant Milk Cooling allows farmers to consolidate the refrigeration equipment to a central “chiller system”, reducing service and maintenance costs.

In some cases, farmers can eliminate their bulk tanks completely by transferring the instantly cooled milk directly into staged milk trucks, reducing additional installation, maintenance, sanitation expense.

INSTANT COOLING IN 4 STEPS

1) Milk is transferred at 101°F from the milking parlor to the milk house

2) With a variable flow pump, the milk is transferred from the DAIRYPro Vat to the PROPlateHX

3) Using 2 stages of cooling, (1) well water and (2) chilled glycol, milk is instantly chilled down to 36°F

4) 36°F Milk is transferred to a bulk tank for storage, or directly onto an awaiting milk truck.
