BUBBLE GUM
EXTRUDER
FORMING LINE

Bubble Gum Extruder

This is where the entire line starts. Raw gum compound is loaded into the extruder hopper. The internal screw (127mm × 660.4mm) rotates and pushes the compound forward, continuously extruding it through the nozzle in a uniform slab shape. The Siemens Germany 7.5 kw motor drives this entire process. An integrated heating system maintains the correct gum temperature for smooth, consistent extrusion. Screw speed is controlled via the 10 kw inverter so the output rate can be adjusted to match the downstream stations.

Rest Conveyor 1

As soon as the gum slab leaves the extruder, it lands on the first rest conveyor. This conveyor carries the slab toward the roller and scrolling line at a controlled, inverter-managed speed. The word "rest" is deliberate: the freshly extruded slab needs a short window to cool slightly and begin setting its shape. Without this buffer, the slab could deform before reaching the roller station. The 8-foot length gives the slab that extra stabilisation time. A food-grade belt ensures hygiene compliance at every direct contact point.

Roller and Scrolling Line

This is the core mechanical stage of the line. The roller and scrolling line uses a press roller set with bracket system to compress the gum slab from both the top and the bottom simultaneously. This brings the slab to an exact, uniform thickness across the full width. At the same time, the scrolling belt keeps the slab moving continuously forward so there is no jamming or bunching at this station. The 5 HP SEW Germany gear motor drives the entire roller set. If the thickness is uneven here, piece sizes at the cutting stage will be inconsistent. The 5-foot press roller set and 5-foot press roller area together ensure the slab is uniform across its full length before it moves on.

Rest Conveyor 2

The roller and scrolling line applied significant pressure to the slab. Before cutting, the slab needs a short settling time so that the cut is perfectly clean and sharp. This second 6-foot rest conveyor is the buffer between the press station and the cutting station. Its inverter-controlled speed keeps the overall line throughput in sync. The food-grade belt maintains hygiene compliance at all direct gum contact points.

Cutting Roller

By this point the slab is perfectly pressed, uniform in thickness, and settled. It passes under the cutting roller, whose blades cut across the slab in the cross direction, producing individual bubble gum pieces at consistent dimensions. The 2 HP SEW Germany motor drives this roller. The rotation speed of the cutting roller determines the cutting frequency and therefore the size of each piece. This speed is adjusted via inverter to match the required piece dimensions. The cutting roller itself is 2 feet and the cutting roller area is 6 feet. After cutting, the pieces drop onto the third rest conveyor.

Rest Conveyor 3

After cutting, the freshly cut gum pieces land on the third 6-foot rest conveyor. Here the pieces cool a little further, the cut shape sets properly, and the pieces naturally begin to separate from one another. At this point the pieces are still slightly warm, and feeding them directly into the 3-step conveyor without this rest period could cause them to stick together. This final rest stage gets the pieces fully ready for the 3-step conveyor and vibration drum. Food-grade belt is consistent across all stages.

3-Step Conveyor

The 3-step conveyor operates across three separate floors. The system gradually transfers cut gum pieces down to the level of the vibration drum. Each floor has its own conveyor belt. The advantage of this multi-floor design is that pieces naturally spread and distribute into a single even layer as they move through, so they arrive at the vibration drum evenly with no clumping. Per the GEW catalog, the main drive gear motor is 1.5 kw, motor power is 2.2 kw, and the air blower is 3 kw. Belt size W 660mm × L 4875mm, 2mm FG belt material. Weight approx 3000 kg. Totally covered with MS sheet.

Vibration Drum

This is the final stage of the line. The SS 304 stainless steel vibration drum receives the cut gum pieces from the 3-step conveyor. The vibration action of the drum separates any pieces that are touching, distributes them evenly, and ensures a smooth, consistent flow toward the next production stage. From here, pieces can feed directly into the GEW coating pan, polishing drum, or wrapping machine. The SS 304 construction meets food-grade hygiene requirements at all direct gum contact surfaces. A dedicated 1.5 kw gear motor and 1 kw inverter control the vibration intensity. Variable capacity with air system and fans for additional piece separation.
