Harmo Food Machinery, a professional manufacturer of chocolate and food processing equipment, has officially announced the launch of its newly developed Chocolate Cooling Tunnel, designed to serve a wide range of applications across the food industry. This innovative cooling solution reflects Harmo’s continued commitment to technological advancement, production efficiency, and equipment reliability.
The new Chocolate Cooling Tunnel is engineered to support multiple food processing sectors. In addition to traditional chocolate cooling, the system is suitable for spring roll cooling, bakery product cooling, and snack processing lines. Its flexible design allows food manufacturers to use one cooling tunnel for different product categories, helping to maximize equipment utilization and reduce capital investment.
With stable temperature control and uniform airflow distribution, the tunnel ensures consistent cooling results, which are critical for maintaining product shape, texture, and surface quality.
One of the key advantages of Suzhou Harmo’s new cooling tunnel is its high compatibility with various chocolate processing machines. The system can work efficiently with:
One-shot chocolate depositors
Chocolate decorating machines
Chocolate chunks extruders
Chocolate vermicelli extruders
This compatibility enables manufacturers to build multi-functional chocolate production lines, allowing easy switching between different product types without major equipment changes. As a result, producers can respond more quickly to market demands and seasonal product development.
Harmo Food Machinery has introduced a creative mechanical improvement by eliminating the traditional correction sensor and pneumatic cylinder system. Instead, the cooling tunnel uses a customized conveyor belt with tendons on both sides.
This advanced belt design ensures the conveyor runs straight and stable at all times, preventing belt deviation during long-term operation. By removing correction sensors and cylinders, the system reduces mechanical complexity, minimizes maintenance requirements, and improves overall operational reliability.
The new conveyor structure also contributes to smoother product transportation, especially for delicate chocolate items and lightweight bakery or snack products.
The newly developed Chocolate Cooling Tunnel offers several key benefits, including:
Stable and uniform cooling performance
Reduced mechanical failure points
Lower maintenance costs
High adaptability to different food production lines
Improved production efficiency and consistency
Its modular design allows customization in length, width, and cooling capacity to meet specific factory layouts and production needs.
With the launch of this new Chocolate Cooling Tunnel, Harmo Food Machinery once again demonstrates its strength in food processing equipment innovation. By focusing on practical improvements and customer-oriented design, Harmo continues to support global food manufacturers with reliable, efficient, and future-ready solutions.
Harmo Food Machinery remains dedicated to delivering advanced chocolate and food production equipment that meets international standards and evolving market requirements.
A chocolate cooling tunnel is used to rapidly and evenly cool chocolate products after depositing, enrobing, or decorating. Proper cooling helps stabilize the chocolate structure, prevent deformation, and achieve a smooth surface finish with consistent gloss and texture.
Yes. In addition to chocolate, Harmo’s cooling tunnel is suitable for spring rolls, bakery items, and various snack products. Its adjustable temperature control and airflow design allow one tunnel to support multiple food processing applications, improving equipment utilization.
The cooling tunnel is designed for seamless integration with one-shot depositors, chocolate enrobers, decorating machines, chocolate chip depositors, chunk extruders, and vermicelli extruders. This compatibility allows manufacturers to build flexible, multi-product production lines.
The system uses precise temperature control combined with evenly distributed airflow throughout the tunnel. This ensures consistent cooling across the entire conveyor width, helping maintain product shape, texture, and surface quality.
Yes. The cooling tunnel features a modular design, allowing customization of length, width, and cooling capacity to match specific production volumes and plant layouts. This makes it suitable for both new installations and existing production line upgrades.
