Products are cooled in a controlled manner by cold air directed to the upper and lower sections as they advance through the tunnel on the conveyor belt. Balanced air circulation ensures homogeneous cooling across all product surfaces. This structure helps create more stable production conditions for different product types.
The system features two independent cooling zones. The temperatures of the inlet and outlet sections can be adjusted independently. This allows suitable operating conditions to be created for different chocolate varieties, coating thicknesses, and production speeds.
The belt conveying system has a width of 1000 mm. The sensor-based and pneumatically assisted automatic belt centering system ensures the belt stays centered during operation, helping products be conveyed in an orderly manner.
The cooling system operates with 2 units of 5 HP cooling groups. The cooling tunnel can be manufactured in different lengths according to the product to be manufactured, production capacity, facility layout, and customer requirements. Thanks to its modular design, it can be easily integrated into new production lines or existing facilities.
The cabinet design has been developed to provide easy access for maintenance and cleaning operations. All surfaces in contact with the product are manufactured from AISI 304 stainless steel. Manufactured using food-grade materials, the system features a hygienic design for easy cleaning.
The electrical control system is built with Siemens brand equipment. The Cooling Tunnel is designed to work with chocolate enrobing machines, chocolate molding lines, coconut bar production lines, and other chocolate production equipment.
