Product Chilling & Hydrocooling

Rapid Product Temperature Pull-Down

Product chilling covers everything from cooling a pumpable liquid to flooding whole produce with near-freezing water. The dividing line is whether the product can go through an exchanger or whether the water has to come to it.

Pumpable product. A sanitary plate exchanger against chilled water or glycol is the efficient answer. Viscosity rises as the product cools, so the cold end works hardest for the least return and the exchanger is sized against the property profile rather than an average.

Whole or delicate product. Hydrocooling in a Temp-Plate bank floods the product with chilled water while the plates keep the water cold. Product never touches a heat transfer surface, which is what makes it suitable for whole items and anything that would foul a channel.

Making the cold water. Both routes need chilled water, and where near-freezing water is required a falling film chiller makes it directly with no secondary loop and no approach temperature given away.
