Freezing according to the Impingement principle is a quick and effective freezing method, widely used in the food industry. This principle is based on the use of high-speed cold air flow to create rapid heat exchange, helping to freeze products quickly and evenly. This not only maintains the quality of the product but also saves time and energy. In this article, we will learn more about Impingement freezing and its applications in the food industry.
Principle of Impingement freezing
Principle of Impingement freezing
The Impingement freezing principle is based on using high-speed cold air flow to create rapid heat exchange, helping to freeze products quickly and evenly.
In the Impingement freezing system, products are moved on flat plate conveyors using stainless steel materials. Thousands of jets and cold air at extremely high speeds will blow directly and continuously onto the top of the product and the bottom of the conveyor belt, along with the high thermal conductivity of the type of conveyor belt used, quickly cooling the product. by two methods: convection and contact heat exchange.
The airflow continuously contacts the product surface so that the product freezes quickly and evenly on the outer surface right from the moment it enters the freezing room, thereby limiting water loss and product wastage. Finished product quality reaches optimal value, bringing high economic efficiency.
The operating mechanism of the freezing system follows the Impingeme principle
The operating mechanism of the freezing system follows the Impingement principle
The Impingement freezing system operates based on the following mechanism:
- Cold air: The system uses high-speed cold air to create rapid heat exchange. This cold air blows directly onto the product and the underside of the conveyor belt.
- Conveyor: Products are moved on flat plate conveyors using stainless steel materials. This conveyor belt has a high thermal conductivity coefficient, helping to enhance the heat exchange process.
- Heat exchange: Rapid heat exchange between cold air and product helps freeze products quickly and evenly. This process helps maintain product quality, limit water loss and product wastage.
- Energy saving: Due to the fast freezing speed, the Impingement freezing system saves time and energy compared to traditional freezing methods.
With such an operating mechanism, the Impingement freezing system has brought high economic efficiency to the food industry.

Applications of Impingement freezing method
Applications of Impingement freezing method
Impingement freezing has many applications in the food industry, including:
- Freezing packaged foods: The Impingement method is used to freeze packaged foods such as meat, fish, packaged vegetables, instant noodles and canned products. Rapid and uniform cooling maintains product quality and freshness.
- Freezing fresh foods: Impingement is also used to freeze fresh foods such as fruits, vegetables, seafood and fresh meat. Rapid cooling helps preserve the natural flavor and nutritional quality of the product.
- Refreezing food: In addition to freezing, the Impingement method is also used to refreeze food products that have been frozen. The rapid and uniform heating process helps maintain the quality and flavor of the product.
- Pre-packaged food production: In the pre-packaged food manufacturing industry, the Impingement method is used to quickly cool ingredients such as sauces, fillings, and other prepared foods before packaging. package.
- Ready-to-eat food production: Ready-to-eat food products such as pizza, pasta and instant noodles are also often frozen using the Impingement method to maintain their flavor and nutritional quality.
These applications indicate that Impingement freezing is an important and versatile technology in the food industry, helping to improve quality and save time during food production.
Investment and operating costs of the Impingement freezing system
Investment and operating costs of the Impingement freezing system
Investment and operating costs for an Impingement freezing system can fluctuate depending on many factors, including the size of the system, technology used, production capacity and specific requirements of each application. Here are some important factors to consider when evaluating investment and operating costs:
- Initial investment costs: Includes the cost of purchasing the Impingement freezing system, cold air injection equipment, conveyor belts and other auxiliary equipment. Initial investment costs can be high for systems with large capacity or advanced technology.
- . Operating costs: Includes energy consumption costs (electricity, gas, fuel), system maintenance and upkeep, labor costs, and other costs such as transportation costs and management costs
- Energy saving: Impingement freezing systems are often highly efficient, which can help save energy compared to traditional freezing methods. The use of natural refrigerants can also reduce operating costs.
- Staff training: The cost of training staff to operate and maintain the Impingement freezing system also needs to be considered to ensure efficient and safe operation.
- Production efficiency: The performance of an Impingement freezing system will affect overall operating costs. High-performance systems typically have lower operating costs because they consume less energy and require less maintenance.
In summary, evaluating the investment and operating costs of an Impingement freezing system requires careful consideration of relevant factors to ensure the effectiveness and feasibility of the project.
Compare Impingement freezing method with other methods
Compare Impingement freezing method with other methods
Comparing the Impingement freezing method with other methods in the food industry can be done based on a number of important criteria such as freezing speed, product quality, investment and operating costs, and save energy. Here is a general comparison:
- Freezing speed: The Impingement freezing method often has a faster freezing speed than other methods such as air freezing or contact freezing, due to direct contact of cold air with the product. However, liquid refrigerant freezing can provide faster freezing rates in some cases.
- Product quality: The Impingement freezing method maintains product quality better than air freezing, especially for products sensitive to rapid temperature changes. Uniform cooling helps preserve the product’s flavor, color and nutritional quality.
- Investment and operating costs: Initial investment costs for the Impingement freezing system are often higher than other freezing methods such as air freezing. However, with high cooling efficiency and energy savings, operating costs can be lower in the long term.
- Energy saving: Impingement freezing is often more energy efficient than other freezing methods such as air freezing, especially when using natural refrigerants. Rapid cooling reduces freezing time and energy consumption.
In summary, the Impingement freezing method is often the preferred choice in the food industry when fast freezing speed is needed, maintaining product quality and saving energy, despite the high initial investment cost. than some other methods.
