Freezer rooms play a vital role in the preservation of frozen products and help businesses manage their inventory efficiently. Proper maintenance and temperature control are crucial to ensure the longevity and quality of the items stored within these specialized cold storage spaces.
Blast Chillers Freezers
A blast chiller or blast freezer is a type of cold room designed to rapidly and efficiently lower the temperature of hot or cooked food to a safe storage temperature. The main purpose of a blast chiller is to prevent bacterial growth and preserve the quality of the food.
How it works:
1. Rapid Cooling: Blast chillers use powerful fans and refrigeration systems to circulate cold air around the food, reducing its temperature quickly. This process is much faster than traditional cooling methods, such as placing the food in a regular refrigerator. Compressors are provides -40° degrees in the cold storage.
2. Food Safety: By rapidly lowering the temperature, the blast chiller minimizes the time that food spends in the “danger zone” (typically between 40°F and 140°F or 4°C and 60°C) where bacteria multiply rapidly. This helps prevent foodborne illnesses and ensures food remains safe to eat.
3. Quality Preservation: The quick cooling process also helps retain the food’s texture, taste, and nutritional value, as it reduces the formation of ice crystals and prevents the food from becoming overcooked.
Blast chillers are commonly used in commercial kitchens, restaurants, catering businesses, and food manufacturing facilities. They are ideal for cooling large quantities of hot food quickly, especially after cooking, before storing it in walk-in freezers or refrigerators. Especially so famous in the seafoods/marine markets. They also use IQF Freezer Tunnel systems too.
By using blast chillers, businesses can adhere to food safety regulations, reduce food waste, and maintain the highest quality of their products.
