What Is The Difference between A Blast Freezer And A Normal Freezer?

When it comes to preserving food, choosing the right type of freezer is crucial. Two common types are blast freezers and normal freezers. But what sets them apart? Let's dive into the details.

What is a Blast Freezer?

A blast freezer, also known as a shock freezer/quick freezer, is designed to freeze food quickly at extremely low temperatures. It typically operates with temperatures ranging from -30°C to -40°C. These freezers are often equipped with advanced features like 200mm thickness sandwich panels, screw compressor rack units, V-type air-cooled or evaporative condensers.

How Does a Blast Freezer Work?

Blast freezers work by rapidly circulating very cold air around the food items. This quick-freeze process turns fresh items into frozen ones in no time. The high cooling capacity ensures that the core temperature of the food drops swiftly, locking in freshness and nutrients.

What is a Normal Cold Room Freezer?

A normal freezer, maintains temperatures around -18°C to -25°,is designed for long-term storage rather than rapid freezing. As usual,food will be transferred to the freezer for long-term storage from the blast freezer.

Key Differences Between a Blast Freezer and a Normal Freezer

Speed of Freezing

Blast Freezer: Quick-freezes fresh things into frozen things quickly.

Normal Freezer: As usual, normal freezer is used to store frozen items for a long time.

Temperature Range

Blast Freezer: Operates between -30°C to -40°C.

Normal Freezer: Operates between -18°C to -25°C.

Components

Blast Freezer: Equipped with screw compressor rack units and V-type air-cooled or evaporative condensers.

Normal Freezer: No need screw compressor rack unit, the single stage piston compressor can meet the requests. The building cost is lower.

Why Choose a Blast Freezer?

Choosing a blast freezer offers several advantages:

Preservation of Quality: The rapid freezing process helps maintain the texture, flavor, and nutritional value of food.

High Cooling Capacity: Ideal for industrial applications where large quantities need to be frozen quickly.

Versatility: Suitable for various settings such as slaughterhouses and food processing plants.

Advanced Features: With components like 200mm thickness sandwich panels and Bitzer screw compressors, they offer superior performance.

In conclusion, while both types of freezers serve their purpose well, blast freezers stand out for their speed and efficiency in industrial settings. If you need to freeze large quantities quickly while maintaining quality, a blast freezer is your best bet.
