Case Study: 8 Sets of 1200MM Chocolate Decorating & Cooling Lines Exported to the USA

In 2025, Suzhou Harmo Food Machinery Co., Ltd. successfully exported eight (8) sets of 1200MM chocolate decorating and cooling lines to a major snack manufacturer in the United States. This project highlights Harmo’s strong capability in chocolate coating machinery, chocolate decorating machinery, and customized food processing solutions for the global market.

Project Background

The U.S. client specializes in producing puffed rice cakes, corn snacks, and cereal bars. They required a high-efficiency chocolate decorating and cooling tunnel that could apply decorative chocolate zigzags on puffed snacks while maintaining consistent cooling performance. The goal was to enhance product appearance, taste, and stability during mass production.

After comparing several suppliers, the customer chose Suzhou Harmo Food Machinery for its advanced design, reliable performance, and proven export experience in chocolate machinery.

Equipment Overview

Each of the eight production lines features a 1200MM chocolate decorating and cooling system designed for continuous, automated operation. The system includes the following components:

Automatic chocolate decorating machine – equipped with precision nozzles that can produce elegant zigzag or linear chocolate patterns on puffed snacks or rice cakes.

Adjustable conveyor belt system – suitable for delicate puffed products, ensuring smooth transfer without damage.

Cooling tunnel with double-layer air circulation system – guarantees even temperature control and stable chocolate setting, preventing cracks or surface defects.

304 stainless steel (SS) construction – ensures hygiene, durability, and easy cleaning, meeting international food safety standards.

This line can be integrated with other chocolate coating, enrobing, or cooling systems, offering flexibility for future product upgrades.

Manufacturing, Testing & Delivery

All equipment was manufactured and assembled in Suzhou, China, under strict quality control. Before shipment, each line underwent full performance testing, including fans flow rate, cooling temperature, and conveyor speed calibration.

The machines were packed securely and shipped to the USA by sea freight. Installation and start-up were completed smoothly under the guidance of Harmo’s remote technical support team. Within one week only, the customer successfully began trial production.

Results & Customer Feedback

The client reported stable production performance, consistent chocolate decoration quality, and high energy efficiency. The zigzag chocolate patterns significantly improved the product’s visual appeal and helped increase sales in the competitive U.S. snack market. The cooling tunnels maintained precise temperature control, ensuring smooth chocolate coating and long shelf life.
