S31 – Rotary forming line for chewing gum

The process begins with pre-extrusion and extrusion, ensuring stable temperature and continuous output.

The extruder produces a rope of gum that is immediately coated with talc or a releasing agent through a dedicated dosing unit, preventing sticking and preparing the product for the next stage.

After this step, the rope sizer ensures the product reaches the correct diameter before the forming stage.

Before entering the forming stage, the product passes through a tempering belt. This step lowers the temperature and relieves internal tensions, allowing the product to release the natural “shrinking effect” and ensuring it is perfectly conditioned for the following part of the process.

At the core of the line, we have the forming machine that houses our latest-generation rotary die sets, where the shaping of the candy takes place.

These rotary die sets are engineered for long production runs with minimal changes, delivering cost efficiency in weight, dimensions, and shape.

The forming process operates at a constant speed between 35 and 110 m/min, supported by sensors placed before, inside, and after the forming machine to guarantee accuracy and consistency.

Speed is fully synchronized with the rest of the line through a PLC controlled system, minimizing human labour operation.

Pneumatic forming pressure provides precise shaping, while the stainless steel tubular frame enables quick cleaning and maximum hygiene.

The final stage is handled by our cooling tunnels, which deliver efficient cooling and direct transfer from forming to packaging.

Cooling is achieved through direct airflow with axial fans, ensuring uniform distribution from the top.

For convenience and hygiene, most tunnel components are fully removable, making cleaning and inspection simple while maintaining the highest production standards, and CIP system is optionally available.
