Having good experience with Pick Heaters in other applications within the plant, the customer contacted the local Pick representative for help. Pick designed a complete package to convert the process to a circulating hot water system. A Pick Heater was installed external to the retort, circulating water at 1,200 gpm while efficiently holding water at the desired temperature of 210°F.
The result was a noticeable improvement in product quality of their canned fruit, with no over or under cooking. The customer identified a quick equipment payback based both on more energy efficiency and reduced product rejection. They are budgeting to make the same change to other retorts in the plant.
