Question: What Does Blast Freezing Mean?

Is a blast chiller colder than a freezer?

The temperature range of a blast freezer varies depending on the manufacturer, but one thing is a fact; it is much colder than your average domestic freezer.

At CRS, our range of blast freezers and chillers are designed with temperature ranges of -40°C to +10°C..

How does a blast chiller work?

To keep up with higher temperatures and constant use, blast chillers use powerful compressors to rapidly pull down the internal temperature of the unit. This ensures that each time cold air is released from the unit it is quickly replaced, keeping produce inside safe and hygienic.

What temperature is a blast freezer?

The Blast Freeze process requires that food be reduced from a temperature of +70ºC to –18ºC in no more than 240 minutes.

How long does it take to blast freeze?

Likewise, how fast does a blast freezer freeze? Blast Freezers reach these temperatures almost instantly, allowing the products that are inside to freeze within 30 to 90 minutes, compared to shock freezers that usually take 90 to 120 minutes, the main difference is the speed at which it can completely freeze a product.

Can you eat 2 year old frozen meat?

Well, according to the U.S. Department of Agriculture, any food stored at exactly 0°F is safe to eat indefinitely. … So the USDA recommends tossing uncooked roasts, steaks, and chops after a year in the freezer, and uncooked ground meat after just 4 months. Meanwhile, frozen cooked meat should go after 3 months.

What is the purpose of a blast chiller?

A blast chiller is a piece of equipment that quickly lowers the temperature of food. Blast chillers are also referred to as blast freezers or flash freezers. They typically have multiple shelves where food pans or sheet pans can be stored and chilled at extremely low temperatures.

What does blast frozen mean?

Whereas standard freezers are kept at 0°C, blast freezing, also know as shock freezing, involves freezers kept at an air temperature of -30 to -40°C. … A longer freezing process results in larger ice crystals, damaging the food and negatively affecting its flavour.

How does blast freezer work?

This is because blast freezers chill and freeze food rapidly. When the large crystals in food frozen by a conventional freezer start to melt, they rupture the preserved food’s cells. … Blast freezers quickly freeze food stored inside thanks to the blowers inside that pass the chilled air over the surface of the food.

How do you blast freeze at home?

To flash freeze at home means to freeze small items individually and bag them quickly once they’re individually frozen. This is an excellent way to treat blueberries: Simply clean them, then lay them on a cookie sheet and place them in the freezer. Once they’re frozen, bag them in a freezer bag.

How much is a blast freezer?

The Freddy blast chiller retails for $2,900, and you can head to Irinox to shop and learn more about how it works.

What does ice crystals in meat signify?

Freezer burn is the result of air coming into contact with food. When food is frozen, a bunch of water molecules within the food form ice crystals. … The loss of these water molecules causes the food to become dehydrated.

How long does a blast chiller take to freeze?

four hoursBlast chillers are designed to bring the core temperature of food from around 160°F or more down to 41°F or less in about 90 minutes. Most units will freeze food in four hours or less. Cutting the time needed to cool food by 75% is a great benefit to any operation.

How do you blast freeze fish?

The general process for blast freezing involves pushing cold air across the fish at a very high velocity and a very low temperature. Freezers can have a variety of sizes and configurations. Some include conveyor belts or moving trays, while others can be used as long-term storage or transportation solutions.

Is a blast chiller a vehicle for contamination?

Vehicles of contamination help micro-organisms move from one place to another and hence can be a route for contamination. Of the listed options, Blast Chillers are not vehicles of contamination. Blast Chillers are a bit like advanced freezers because they are used to freeze food at a fast rate.

What is the difference between flash freezing and freezing?

Well, quite simply, your home freezer is not designed to freeze foods, it’s designed to keep frozen foods cold. … 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.

What is quick freezing?

transitive verb. : to freeze (food) for preservation so rapidly that ice crystals formed are too small to rupture the cells and the natural juices and flavor are preserved.

How cold is a flash freezer?

In physics and chemistry, flash freezing is the process whereby objects are frozen in just a few hours by subjecting them to cryogenic temperatures, or through direct contact with liquid nitrogen at −196 °C (−320.8 °F). It is commonly used in the food industry.
