Cooling tunnel for center cooling in confectionery production
Efficiently manage center cooling in confectionery production with advanced modular designs, ensuring optimal temperature control and energy savings.

Cools and Insulates Confectionery Products Efficiently
The Thermo-Flow®+ KK from Sollich KG is a cooling tunnel designed to meet the demanding needs of confectionery and snack manufacturers. This equipment stands out with its dual convection and contact cooling technology, crucial for maintaining the integrity of chocolate, candy bars, and cereal-based products. With its modular construction, the Thermo-Flow®+ KK is adaptable to various production environments, providing energy-efficient cooling and insulating capabilities with minimized energy loss due to its “all around insulation” design.
Engineered for continuous, high-speed operations, this cooling tunnel works seamlessly with other equipment such as tempering and enrobing machines, ensuring a smooth transition and integration into existing production lines. It achieves uniform temperature and airflow distribution, which is essential for products like milk chocolate squares, peanut butter candy bars, and protein bars. The system features a stainless steel construction option and offers belt widths ranging from 620 mm to 820 mm, featuring the innovative Gullwing cover design for enhanced accessibility and ease of cleaning.
The Thermo-Flow®+ KK also boasts robust automation features, with options for integrated air drying, belt washing devices, and cooling compressors. Thermo-regulation of the belt is available for specialized applications, ensuring precision and quality control. This cooling tunnel is not only an asset for standard confectioneries but extends its utility to bakeries and snack manufacturing industries, supporting product versatility and innovation.
