How Does a Dual-Hopper Gummy Depositor Work?
Gummy Molds Team
A dual-hopper gummy depositor is designed to keep two product masses available at the depositing system at the same time. That makes it useful for compatible two-color gummies, center-filled gummies, and other confectionery formats that require controlled delivery of more than one mass.
The exact depositing pattern depends on the head configuration, recipe behavior, mold geometry, machine settings, and intended finished product.
What Makes a Dual-Hopper Depositor Different?
A conventional single-hopper machine holds and deposits one gummy mass at a time. A dual-hopper machine has two separate product supply paths, allowing two formulations, colors, flavors, or components to remain separate until they reach the depositing stage.
This separation creates more production options, including compatible:
- Two-color gummies
- Two-tone gummies
- Center-filled gummies
- Shell-and-center confection formats
- Selected hard-candy applications when the machine is configured for the process
How the Two Product Masses Move Through the System
Each hopper supplies its own side of the depositing system. The machine controls delivery so the two masses can be dispensed according to the selected depositing setup. Depending on the product format, they may be deposited in a coordinated pattern rather than simply mixed together.
On the Gummy Molds dual-hopper depositor, the system has 20 nozzles total — 10 per hopper. The machine also uses Siemens PLC control and a high-precision servo drive for controlled commercial operation.
How Center-Filled Depositing Works
Center-fill production requires the outer mass and center material to stay separate through the depositing system. The goal is to deliver the center inside the surrounding shell rather than placing two visible masses side by side.
That requires coordination between shell viscosity, center viscosity, deposit timing, piece geometry, mold registration, and depositing-head configuration. Read What Are Center-Filled Gummies? for a broader production overview.
How Two-Color Depositing Works
Two-color gummies also use two masses, but the desired visual result can be very different. Depending on the setup, the two colors may form separate zones, layers, or patterns. A dual-hopper machine gives the operator two independent product sources so the finished design does not require premixing the colors before depositing.
Two-color and center-filled gummies both use two product masses, but they require different depositing objectives. Two-color production emphasizes visible separation or patterning; center-filled production requires controlled placement of the center inside the outer shell.
Why Nozzle Layout Matters
Nozzle count by itself does not determine whether a machine will work with a mold. The mold must also align with the nozzle spacing, cavity centers, tray or carrier position, indexing pattern, machine clearance, shot requirements, and formula.
Use the Gummy Depositor Compatibility Guide to evaluate machine and mold fit before buying production quantities.
Why Mold Design Matters
A mold for automated depositing must be planned around more than the shape of the gummy. Important factors include:
- Overall mold dimensions
- Cavity spacing and center locations
- Number of cavities presented to the nozzles
- Tray or carrier dimensions
- Registration and repeatable positioning
- Target piece volume
- Shell volume and center-fill requirements for filled products
If an existing mold does not match the machine layout, a custom commercial gummy mold can be developed around the actual equipment geometry.
Temperature Control and Product Flow
Gummy and candy masses must remain within an appropriate working range during depositing. Too much cooling can increase viscosity and make controlled depositing difficult. Excessive heat can change the behavior of a formulation or create quality issues.
For hard-candy applications, the depositor is not the cooker. The candy mass is cooked separately and then transferred to the depositing system, where the goal is to maintain suitable working conditions for filling. Regular hard candy may be cooked around 302°F (150°C), sugar-free hard candy around 329°F (165°C), and soft candy commonly around 239–248°F (115–120°C), depending on the formulation.
What Does the PLC Control?
Commercial depositing systems use controls to manage the repeatable machine sequence. The exact adjustable settings vary by configuration, but a PLC-based interface can centralize machine operation and help coordinate depositing actions.
The dual-hopper model sold by Gummy Molds uses a Siemens PLC and servo drive. We do not publish unverified speed, deposit-range, or throughput figures until they are confirmed for the exact production configuration.
Single-Hopper vs. Dual-Hopper Depositors
A single-hopper machine can be the simpler choice when you are making one-color gummies from one mass. A dual-hopper machine becomes more relevant when the product requires two separate masses at the depositing system.

Planning a Dual-Hopper Production Line
Start with the finished product rather than the machine. Define the piece size, formula type, whether the gummy is one-color, two-color, or center-filled, target production method, mold layout, and downstream setting requirements. Then select equipment and molds around that production target.
The Commercial Gummy Molds Buyer’s Guide and Gummy Mold Production Calculator can help plan the tooling side of the line.
Dual-Hopper Depositor from Gummy Molds
Our Dual-Hopper Automatic Commercial Gummy Depositor is intended for compatible two-color, center-filled, and hard-candy production. It has 20 nozzles total, with 10 nozzles per hopper, Siemens PLC control, a servo drive, and SUS304 stainless-steel construction.
Because multi-mass depositing is highly product-specific, final machine configuration should be reviewed against the actual recipe, mold, target geometry, and production setup before ordering.
