US fruit processing plant turns to HRS team 04 July 2013

HRS Process Technology has successfully installed heat exchanger and pump systems for an aseptic fruit processing plant in Oxnard, California.

The system, which includes a DTA-series heat exchanger and a BP8 and BP10 positive displacement pump, will process 4 tons per hour of aseptic sliced and diced strawberry in syrup.

Carlos Cobian, general manager, HRS Process Technology, explains that this is the second time HRS has been involved with the Oxnard plant, adding that industrial treatment of products, such as whole or diced fruits, can be challenging since the product can easily be damaged.

"The success of our technology for fruit dices aseptic plants is based on our corrugated double tube heat exchangers, piston pump and our aseptic filler," comments Cobian.

"Combining them makes it possible to process the fruit pulp and purée, minimising the undesirable thermal effects and getting a reliable, hygienic and well controlled filling process," he adds.

Designed to overcome many challenges associated with traditional pumps,

Cobian cites HRS' BP-series reciprocating positive-displacement pump, for example, which is a hydraulically operated unit delivering high flow rates and high-pressure drop, but without the problems of traditional pumps used with delicate product.

Its hygienic design, combined with a good response to CIP (cleaning in place) makes this pump suited for food processing applications, especially for particulate and low shear rate products.
