Understanding Blast Chiller Capacities

Blast chiller capacity measurements can be confusing, especially for those who are new to the industry. To start off, it’s important to know that blast chillers can come in various sizes, from countertop to floor-standing units. The capacity of a blast chiller is typically measured in terms of how many standard-sized pans, trays, or GN (Gastronorm) units it can hold. Standard-sized sheet pans usually come in full, half, and quarter sizes, and GN units are typically used in European kitchens.

When it comes to capacity options available in the market, blast chillers can range anywhere from holding a few pans to several dozen. Common capacities include 3, 5, 10, 20 and 40 GN units. A countertop blast chiller might have a capacity of 5-10 standard-sized pans or 3-5 GN units, while a larger floor-standing model could hold up to 40 GN units. The right capacity for your kitchen depends on a variety of factors such as the size of your kitchen, the volume of food you need to chill, and the type of food you’re preparing.

Matching blast chiller capacity to your kitchen’s output and demand is critical to ensure that you’re not sacrificing quality or efficiency. If you’re running a small café that does not have a lot of space, a 3-5 GN unit blast chiller or a countertop model with the capacity to hold a few pans might be sufficient. However, if you’re running a high-volume restaurant or catering business, a larger floor-standing model with the capacity to hold 20 or more GN units could be the best option. Not having the right blast chiller capacity could result in food not being chilled fast enough, leading to bacteria growth and unsafe storage.

Another important factor to consider when choosing a blast chiller is the rate at which it can chill cooked food. Blast chillers vary in their chilling times, with some models being able to bring food from the cooking temperature to a safe temperature within 90 minutes, while others can chill cooked food to a low temperature within 240 minutes. A fast-chilling model can improve kitchen efficiency and ensure food safety, but it usually comes with a higher price tag.
