How does flash freeze work?
Flash Freezing food focuses on rapidly freezing the product so as to maintain proper retention of moisture, flavor and texture. It accomplishes this via high speed internal cooling. It rapidly cools down the internal temperature in the freezer, making it much easier to ensure efficient cooling for the product.
How does a blast freezer work?
Blast chillers or freezers operate by blowing forced cooled air over food placed inside. When defrosting food, large ice crystals melt and cause excess moisture to release, which largely impacts the taste and quality of your food products.
What is the difference between flash freezing and freezing?
When you put unfrozen foods in your freezer, it takes hours to freeze them fully. In contrast, when you flash freeze meats, they are frozen so quickly that the ice crystals don’t form between the fibers of your meats.22 Sept 2017

How long does a blast freezer take to freeze ice cream?
Unlike the macro crystals that are formed on slow freezing, the micro crystals do not damage the structure of the product on defrosting so it keeps its original consistency without the loss of any liquid from the structure. Blast freezers can harden off the outside of the ice cream in around 25 minutes.
Is flash freezing safe?
But did you know that produce that’s flash-frozen may be healthier than the fruits and veggies sitting in your fridge?

Can you blast freeze ice cream?
This process consists of storing your ice cream in a blast freezer in order to lower its temperature even further (to -18/-20°C) without stirring it.
What is the temperature of a blast chiller?
Blast chillers drop food temperatures from 160 degrees F to 35 degrees F in 4 hours or quicker with some models. Blast chillers bring food temperatures down using a combination of cold and moving air across the product, which expedites the process.
Is flash freezing the same as freeze drying?
The key difference between flash frozen and freeze dried food is that the former process doesn’t remove moisture from the meat. Most freeze dried dog foods show around 5% to 7% moisture in the Guaranteed Analysis, compared to 70% or more in flash frozen raw food.17 Dec 2021
