Blast Freezers: Common Applications and Working

1. Blast freezers: Common Applications and Working Blast freezers, also known as flash freezers or shock freezers, are a cold storage solution that quickly freezes items, especially food, at very low temperatures. The quick freezing protects the food from harmful bacteria or microorganisms as it prevents their growth. These freezers can store items at temperatures ranging from -40 to +40 degrees Celsius (the temperature capacity of a blast freezer varies based on their model). This blog briefly explains this cold storage solution that the blast freezers rental service offers. How Does Blast Freezers Work? Before we understand how a blast freezer works and why it is preferred over normal freezers, let us look into the workings of a normal freezer to understand a bit better. Freezing happens when the water inside the food item transforms into ice crystals. Normal freezers take time to freeze the contents, which leads to the formation of big ice crystals. When the big ice crystals defrost, they damage and distort the cell structure of the item, affecting the food's texture and quality.

2. In contrast, a blast freezer freezes the item in no time, even at extremely low temperatures. The freezing happens when the blower releases cold air, leading to smaller ice crystals forming. As a result, the cell structure is preserved, which minimizes the alteration in the texture and quality of the food. However, storing hot food in high quantities in the blast freezer is not recommended. This is because the internal temperature of the blast freezer can increase, and the blower will release warm air. The freezer will then work on cooling the warm air and the food item, ultimately delaying the cooling process and reducing its effectiveness. Some blast freezers have movable trays that allow customizing the food position to ensure it is cooled evenly. What are the Applications of Blast Freezers? Blast freezers are portable cold storage solutions made for commercial applications. They are used across industries for rapid chilling the product at manufacturing site; however, some of the most common and important applications are: •Hotels, restaurants, commercial kitchens, and other businesses dealing in the food industry use blast freezers to preserve cooked food, food stock, and meals. •Confectionaries use blast freezers to store desserts, ensuring the texture and taste remain unchanged. •Pharmaceutical or healthcare industries use this to store vaccines, clinical trials and certain medications. •The dairy industry uses blast chillers to store dairy items like curd, flavored milk, cottage cheese, etc., to ensure the product quality remains intact. •Cold storage companies use blast freezers in commercial units.

They work by rapidly freezing the contents, thereby maintaining the food's
