Which to choose: Blast chiller or refrigerator?

Choosing the right kind of refrigeration for your hospitality business is a huge decision. A commercial fridge is specifically designed for frequent use, in busy professional kitchens. Whether you are running a small cafe or restaurant, food must be kept chilled at the right temperature and displayed in a visually pleasing manner.

In commercial kitchens, there is often a need to cool down cooked food quickly, in order to safely store it for use at a later date. It used to be thought that chilling it down to room temperature, followed by storage in a fridge, was sufficient for most food applications.

However, we know that the temperature of food needs to be reduced in a much more controlled manner. The safest way to comply with the food safety regulations governing the chilling and freezing of cooked food is to use a blast chiller, or blast freezer.

Why can’t you use a standard fridge for this? The benefits of having a blast chiller for food safety, food quality, labor savings, and decreased food waste make the investment a no-brainer. But, what do you really need to know to make a smart investment and reap the benefits that come with this game-changing addition to your line-up?

Some of the questions you might be asked by a commercial equipment supplier, like our kitchen division, Butler Equipment, are:

Does your commercial fridge cool food quick enough?

When fridge doors are continually being opened, the unit requires a faster chill recovery rate and has to work far harder to maintain its storage temperature. As a result, commercial fridges are made with powerful compressors, far sturdier construction. They are often fan-assisted and this makes them louder than domestic fridges. Depending on your menu and your food demand, your kitchen may need to prep food in bulk. Your refrigerator needs to be up to the task of chilling the food quick enough, without dropping the overall temperature inside the fridge.

Have you looked at the main functions of a blast chiller?

One of the main features of this kind of unit is that it rapidly cools down your food, until it’s at a safe point to store in a refrigerator. This happens by blasting the food with cooled air for an extended period of time. A standard blast chiller will chill from 70°C to 3°C in less than 90 minutes. A blast freezer will chill from 70°C to – 18°C in less than 240 minutes.

Blast Chillers are your best choice for rapidly freezing food products for longer term storage. It also means you’re able to purchase bulk products in season/at a lower price. Blast freezing allows chefs to prepare menu items and rapidly freeze for later use. Food products prepared in this way will maintain their cellular structure, taste and appearance as if they were just prepared for the first time. It will also simplify your overall commercial kitchen ordering process – you can plan more effectively and minimise disruptions to your menu caused by a lack of availability.

Will these features help you operate more effectively and sustainably?

A blast chiller system can also streamline production processes, enabling staff to work faster and more effectively. This gives you the flexibility to adjust your staffing levels to meet demand, as well as manage your overall operating costs. Blast Chillers will also help you meet food safety requirements by reducing the potential growth of micro-organisms, which result in your food deteriorating more quickly.

In many traditional kitchens, it is common practice to place warm food into a fridge or freezer to bring the food down to 3°C or – 18°C respectively; this practice results in the fridge or freezer having to operate outside of its designed capabilities. This equipment misuse can result in increased power and service costs, as well as a shortening of the equipment’s expected life cycle.

Remember a cool room or fridge is designed to keep cold food cold and a freezer room is designed to keep frozen food frozen.

What is the best one for your operation?

Your restaurant concept and its size will be the biggest factors in what you buy for restaurant refrigeration. There is a wide range of sizes of Blast Chillers to fit various work spaces, volumes, and budgets.

Low profile versions are designed to fit under a combi oven for convenient transfer of food pans from oven to chiller. We love the Olis Blast Chiller – Shock Freezer 5 x 1/1 GN which is perfect for under counter convenience.

Our recommendations for other larger volume models by Olis range are as follows:

8 tray x 1/1 GN Olis Blast Chiller – Shock Freezer
Olis 12 tray x 1/1 GN Olis Blast Chiller – Shock Freezer
