One-shot Chocolate Depositor

A stand-alone one-shot chocolate depositor for molded and center-filled chocolates. The machine is supplied with its own rigid C-frame chassis for easy installation into new or existing molding lines, and can be integrated with mold conveyors or belt-based depositing systems depending on configuration.

Types of chocolate depositors

We produce one-shot depositors for artisan workshops and industrial chocolate manufacturers. Depending on configuration, the machines are designed for depositing into molds or for belt depositing of drops, coins, or filled portions, and can be integrated into new or existing molding lines.

Design and operating principles of the one-shot chocolate depositor

The NGOSD-CV series is a new generation stand-alone one-shot depositor with a traditional common valve mechanism for suction and pouring pistons. It is suitable for chocolate molding lines and drop/coin applications where stable temperature and repeatable cycle control are required. Servo-driven Z-axis motion supports accurate nozzle positioning, while PID-controlled dry heating stabilizes chocolate and filling temperature.

NGOSD-SV series one-shot depositors use a specially designed separate valve mechanism for each cylinder to improve weight accuracy compared to the CV series. With servo-driven pouring and touchscreen control, deposit weight can be adjusted quickly. Dry heating, servo Z-axis motion, servo suction (suck-back) and per-cylinder valve control are the key functional improvements for repeatable molded and center-filled deposits.

What is one-shot depositing?

One-shot depositing is a molding method where chocolate shell and filling are deposited in a synchronized cycle. The depositor controls dosing and timing so the chocolate and center can be formed in one operation, which is used for molded pralines and center-filled chocolates.

Servo-driven suction and pouring for clean deposits

Servo-driven suction (suck-back) helps prevent dripping and stringing at the nozzle. Servo-driven pouring/dosing provides repeatable stroke control for deposit weight adjustment and stable filling/chocolate ratio. Servo-driven Z-axis motion improves nozzle-to-mold positioning consistency and supports faster indexing and cycle repeatability.

Stand-alone design for line integration

NGOSD series one-shot depositors are stand-alone with their own chassis and can be integrated into molding lines between chocolate tempering and cooling tunnel. The machine can be configured to synchronize with mold indexing and production speed depending on the line layout.

Auxiliary equipment

Chocolate storage tank ST2000INS

The storage tank is equipment to hold chocolate in a homogeneous and liquid condition; it is used to feed the tempering machine, which will form the crystal structure of the chocolate.
