Chilling and Freezing Applications
Dowcal N is used for cooling liquid food is used extensively by breweries, wineries, dairies, and fruit processors to cool liquid food during processing, restaurant bars and vending machines. The usage in beverage processing provides dependable temperature control and lower temperature capabilities than water when 30% to 45% of the solution is circulated through cooling coils.
Also used by breweries and wineries to cool fermentation and wort tanks, Dowcal N is chilled in a primary refrigeration unit and then circulated through coils submerged in- or wrapped around the tank. Considering that heat transfer fluid can have an accidental contact with beverage, the fluid is low in odor, toxicity and tasteless. Also, Dowcal N does not affect the foaming of fermenting properties of beer or wine, noticing that the low temperature capability permits recovery of CO2 generated while fermenting, which is used later in the bottling process.
Immersion freezing of wrapped foods
Used for immersion freezing by processors of wrapped meat, poultry, fish, seafood, vegetables, and fruit. Dowcal N provides faster freezing of foods than air or plate freezing, so production rates are increased, also the speed it freezes reduces surface bacteria counts which improves shelf life from products.
In an immersion freezing process, food is tightly wrapped and sealed in airand water-tight bags. Secondly, it is immersed in a freezing bath at 11°C of 40-to-50 percent DOWCAL™ N fluid in solution with water.
Packaging carbonated beverages
Before carbonated beverage are bottled, they are chilled to prevent loss of carbonation. In champagne production, inverted bottles of aged champagne are dipped in a chilled bath of DOWCAL™ N fluid, freezing the contents in the neck of the bottle. This traps sediment for removal. Consistent product chilling is achieved because system equipment is easy to operate and fluids are easy to maintain and adjust.
Plastic bottle blow molding
To blow mold plastic bottles, packaging companies need to cool their molds. Dowcal N is the optimal solution because fluids remain liquid at lower temperatures than plain water, they cool moulds faster, increasing production.
Dowcal N is also a great solution for Ice production so water can be frozen quickly.
