One-Shot Chocolate Depositor

NGOSD10CV or NGOSD20CV — which model?

Maximum shot weight decides. Both run at up to 20 shots/min and share the common valve mechanism, servo Z-axis, servo suck-back, and PID-controlled dry heating:

• NGOSD10CV: up to 500 g/shot, smaller chassis, 4.2 kW. Choose when combined shell-plus-filling weight is under 500 g per shot.
• NGOSD20CV: up to 1000 g/shot, larger chassis, 5 kW. Choose above 500 g/shot.

Picking NGOSD10CV above 500 g/shot hits the per-shot ceiling and forces a multi-pass cycle that breaks the one-shot principle; picking NGOSD20CV for products well under 500 g/shot pays for unused chassis and an extra 0.8 kW. The model is fixed at order — chassis and piston-cylinder geometry are sized at manufacture, not field-changeable.

What is one-shot depositing and what is the CV series for?

One-shot depositing forms the chocolate shell and the filling in a single synchronized cycle: shell chocolate and filling are dosed simultaneously through concentric pistons into one mold cavity, eliminating the separate shell-then-fill steps used on shell-molding lines. The NGOSD-CV series uses a common valve mechanism — one shared valve serves all suction and pouring pistons across the manifold, which keeps the chassis simple and the cost lower. CV fits production where shell-to-filling weight ratio across cavities holds acceptable tolerance with shared valve timing. Tighter per-cavity weight accuracy requires the NGOSD-SV (separate valve) series with a dedicated valve per cylinder; SV is not on this page.

CV or SV — when are separate valves required?

Common valve (CV) shares one valve mechanism across all suction and pouring pistons. Across cavities, deposit weight tracks together but absolute weight tolerance per cavity depends on viscosity uniformity in the manifold. Separate valve (SV) gives each cylinder its own valve, allowing independent per-cylinder weight control and tighter tolerance across the full mold. CV fits standard molded chocolate and center-filled production with normal commercial weight tolerance. SV is required when product specification or downstream weight-check rejects mandate per-cavity weight control. The SV series is a different machine and is not field-converted from CV.

Stand-alone or bundled with a molding line — which page is which?

Chassis shipment decides which page applies:

• Stand-alone (this page): NGOSD-CV on its own C-frame chassis, for retrofit between an existing tempering machine and cooling tunnel, or above a belt for drops/coins/filled portions.
• Bundled, semi-automatic: NGOSD16SV-ML — depositor with cooling tunnel, manual demolding, on the chocolate-molding-machine page.
• Bundled, fully automatic: SML500 — full molding line with elevator cooling tunnel and automatic demolding, on the high-capacity molding line page.

Picking stand-alone when cooling tunnel and demolding are also missing leaves the rest of the line to source elsewhere; picking a bundled line when only the depositor is missing pays for components the plant already has.

Mold depositing or belt depositing — same machine?

Same machine, both modes. NGOSD-CV deposits into polycarbonate molds (pralines, tablets, center-filled chocolates) when installed above a mold conveyor, or onto a cooling-tunnel belt (drops, coins, filled portions) when installed above a belt. Mode is set by mounting position and PLC recipe — belt speed, shot frequency, suck-back stroke, and Z-axis travel are stored per format and recalled by the operator without mechanical changeover. Constraint: belt mode does not produce shaped lentils with engraved top profiles — those need cavity drums on the RD600 roller depositor. CDFL chocolate drop lines are dedicated belt-depositing lines for high-volume drops/chips/buttons production with their own cooling tunnel and two-zone belt; NGOSD-CV in belt mode covers ad-hoc belt depositing inside a molding-line plant, not dedicated drop production.

What feeds the NGOSD-CV from upstream?

Tempered chocolate, supplied via the chocolate storage tank. Tempering grade splits by model: NGOSD10CV requires a continuous tempering machine — its smaller shot weight and finer cavity work depend on the highest-grade crystal form for gloss, snap, and clean mold release. NGOSD20CV is fed by an industrial tempering machine — the 1000 g shot weight and the chocolate types this model runs match industrial-grade tempering output. The depositor's PID-controlled dry heating holds the depositor body and three-way valves at working temperature but does not temper — it conditions already-tempered chocolate against thermal loss inside the manifold. Feeding untempered chocolate produces molded pieces without gloss, without snap, and with poor mold release. Wheel-type batch temperers drain between cycles and break the depositor's hopper level-sensor feed loop; they are not used upstream of either model.

What does the NGOSD-CV not do?

• Not a tempering machine — chocolate must arrive already tempered.
• Not a cooling tunnel — deposited molds or belt need a separate cooling tunnel downstream.
• Not a demolder — pieces release on a downstream demolding station or by hand.
• Not for shaped lentils with engraved top geometry — those are formed between cavity drums on the RD600 roller depositor.
• Not for spreads in jars — that is the TTSCF100 spread filling machine, a gear-pump-based depositor.
• Not field-convertible to the SV series — separate-valve is a different machine.
