Three types of cooling
1. Direct cooling
Air circulates both above and below the products, achieving a maximum airspeed of 3.2 m/s. This gentle method effectively removes BTUs from the product, ensuring optimal cooling.
2. Indirect cooling
Chilled air gently falls over the articles through radiation. Indirect cooling offers a stable and seamless process that ensures uninterrupted product quality.
3. Combined cooling
Our system is designed to provide softer cooling at the beginning of the process, gradually intensifying towards the end to minimize fat bloom effectively.
