1. Faster freezing and Consistent freezing: Impingement tunnel freezers use a high-velocity air jet to rapidly freeze the product, resulting in faster freezing times than traditional methods. The impingement air jet ensures even and consistent freezing of the product, preventing freeze-thaw damage and preserving the quality of the food. Compared with conventional stationary impinging jets, self-excited oscillating impinging jets have a higher Nusselt number, which improves heat transfer during the cooling process. 2. Space-saving design: Impingement tunnel freezers are designed to take up minimal space in a production facility, allowing for maximum efficiency in production. The high-velocity air jet enables quicker freezing times and reduces overall energy consumption compared to traditional freezers. 3. Improved product quality and Increased productivity: The rapid freezing process and consistent freezing temperature helps to preserve the texture, color, and flavor of the product, resulting in higher quality food. The faster freezing time and consistent temperature control allow for higher production output and reduced downtime in the production process.
