Description
DCN static DA coolers are designed for large-batch cooling in stand-alone vessels. Their unique scraped-surface agitators and large surface-area-to-product ratio allow rapid cooling without damaging particulates or affecting quality and taste.
Process
Product is transferred into the cooler by a vacuum transfer system. The cooling cycle is closely monitored to prevent thermal shock and separation. After cooling, the product can be pumped out or transferred into vessels using sterile-air over-pressure, then taken to the filling line for depositing – reducing product damage and losses.
Standard batch sizes range from 300 to 1,000 litres.
