What Is The Machine That Freezers Food Quickly?

In the modern food industry, rapid freezing technology has become a key link in ensuring food safety and quality. The core of this technology is to freeze food in a short time by extremely rapid cooling, thereby maximizing the integrity of the food’s cell structure. But what is the machine that freezes food quickly?

Freezing machine are the most commonly used equipment in food processing plants. This equipment uses a continuous operation mode, where food is placed on a conveyor belt and passes through a low-temperature tunnel at a constant speed. The temperature in the tunnel can be as low as -40°C, and strong cold air flows at a speed of 3-5m/s to ensure that the food is frozen quickly and evenly. For example, traditional freezing of green beans takes more than 2 hours, while tunnel freezing only takes 8-15 minutes to complete the freezing process.

Rapid freezing preserves food quality at multiple levels. At the cellular level, the rapidly formed tiny ice crystals do not puncture the cell wall, maintaining the integrity of the cell structure; at the nutritional level, the loss of heat-sensitive nutrients such as vitamin C can be reduced by more than 60%; in terms of sensory quality, the color, texture and flavor of the food can be better preserved. Data shows that the chlorophyll retention rate of spinach using rapid freezing can reach 95%, while that of traditional freezing is only 75%.

The application scope of this technology is constantly expanding. From the initial fruits and vegetables to today’s seafood and pastries, rapid freezing is reshaping the entire food supply chain. It not only extends the shelf life of food, but more importantly, it preserves the nutritional value and sensory properties of food to the greatest extent, allowing consumers to enjoy food that is close to fresh in any season.

As consumers’ requirements for food quality increase and cold chain logistics improve, refrigeration technology will play a more important role in the food industry.
