What Is Blast Chilling? The Basics of Blast Freezing
Why blast chilling and freezing is important. What is the 'danger zone'? What are the Department of Health Guidelines? These are the types of questions that as a cater you should know the answers to, howveer blast chilling and freezing is not as straight forward as standard reach-in refrigeration as there is a process to handling food safely.
How does a blast chiller work?
When large amounts of ice crystals melt, they increase the amount of moisture and can hamper the overall quality and taste of food. By decreasing moisture, the blast chiller’s cooling process helps maintain the best possible quality and taste.
Why is a blast chiller important?
Both the cooling process and temperature play a crucial role in preventing bacteria growth. Bacteria like E.coli and Staphylococcus grows rapidly between 40°F – 140°F, which is commonly referred to as the “ danger zone .” Improper refrigeration or freezing can spur this on if it allows food to stay in this temperature range for a prolonged period of time. This is why a blast chiller is a major asset. Its ability to quickly lower food temperature keeps any product out of that danger zone.
How long can you freeze food in a blast chiller?
The unit’s temperature varies based on manufacturer and model. According to Foodservice Equipment Reports, most commercial blast chillers help food reach a core temperature of “around 160°F or more down to 41°F or less in about 90 minutes” and can “freeze food for four hours or less.” This rapid temperature decrease plays a key role in preventing the growth of bacteria, which we’ll address next.
What is a blast chiller?
A blast chiller, also known as a flash freezer , is designed to lower food temperature quickly. Equipped with multiple shelves, your customer can freeze multiple types of foods all at once. While commercial kitchens use the unit to rapidly freeze product, many also use it to thaw and temporarily chill batches of food, such as pastas, breads or freshly made desserts like ice creams and sorbets.

How to cool food in a blast chiller?
Tips for cooling food effectively 1 Only fill to capacity – Filling your blast chiller above the capacity stated will damage the effectiveness of your unit and can slow the cooling process, leading the bacterial development. 2 Regularly check temperatures – It’s important to regularly check the temperature of your blast chiller to ensure that everything is working correctly. Not doing so could lead to a temperature failure going unnoticed and potentially contaminated food being served to customers. 3 Rotate food regularly – To ensure that old food doesn’t get left in your chiller, use a rotation system that ensures older food is moved to the front of the unit before new food is put in. 4 Clean your chiller regularly – Blast chillers are safe and hygienic environments but even they aren’t immune to leaks and spills. Remember to clean out your unit regularly to avoid cross contamination.

How Does a Blast Chiller Work?
First, you place a tray with food or drinks inside the blast chiller. Once you start the process, the blast chiller fan turns on and cools the product with cold air. This approach also minimizes the product loss that occurs during evaporation, and the smaller ice crystals do less damage to the food when it thaws. All in all, the blast chiller process results in tastier, more tender, and more nutritious food compared to traditional refrigeration or freezing.
How Does a Blast Chiller Preserve Nutritional Health?
Finally, a blast chiller retains more nutrients than other freezing methods. When you freeze food using normal, more harsh means, the nutrients start to deteriorate and the product loses its flavor. Frozen food is extremely useful for ready-cooked meals, but the quality can be lost if you’re not using a blast chiller.

What is a Blast Freezer?
A Blast Freezer (also known as “blast chiller”, “blast chiller freezer”, or “shock freezer”) is a specialized category of freezer used to preserve food at a very low temperature (very cold) to prevent the growth of microorganisms. A Blast Freezer is also known as Blast Chiller.
History of Air Blast Freezers
Up until 1842, food was preserved by soaking in salt and ice brine. This method was commercially utilized till the advent of a mechanical refrigerator. In 1880, the first refrigerated frozen meat cargo was shipped from Australia to Britain.
How Blast Freezers Work
In ordinary refrigerators, when a food gets frozen, the water inside it crystallizes. The crystals formed inside the food are relatively larger in size. When a large crystal melts, it ruptures the cells of the preserved food. Eventually the texture and taste of the food gets deteriorated.
Conventional Refrigerator vs Blast Chiller
In a conventional refrigerator, food is stacked one above another. The air circulating inside gets stagnated. The cold air pumped by the cooling coils has to cool both the stagnant air and the food. That is the reason for which ordinary refrigerator takes longer time to cool. However, a Blast Freezer has a different arrangement.
Pros and Cons of Blast Freezers
A Blast Freezer locks the color, texture, flavor, and nutritional value of the preserved food quickly.
How Do Blast Chillers and Freezers Work?
Blast chillers and freezers will decrease the temperature of your freshly cooked food to storage temperatures and help you avoid any bacteria growth or spoilage.
