Chocolate depositor NGOSD series

one-shotfor the food industryin-line

Overview
A one-shot chocolate depositor that produces the shell and the filling in a single synchronized cycle. Supplied as the NGOSD-CV series with four base models (NGOSD10CV, NGOSD20CV, NGOSD36CV, NGOSD60CV). Machine mounts downstream of a tempering unit and upstream of a cooling tunnel or demolding station. PID-controlled dry heating prevents blockages and cold-start dosing; servo-driven dosing and servo suck-back deliver repeatable deposits and prevent stringing.

Process suitability

• Deposits shell chocolate and filling into each mold cavity in one synchronized cycle.
• Designed to integrate after a tempering machine and before a cooling tunnel; requires continuous tempered chocolate feed sized to shot weight and cycle rate.
• Choose a stand-alone depositor when cooling/demolding are supplied separately; choose a bundled molding line when cooling and demolding must ship together.
• Solid inclusions: only NGOSD10CV accepts inclusions up to 2 mm and only via the filling path; other models require inclusion-free products.
• Maximum total deposit per cavity depends on model: 500–1200 g.

Decisions fixed at order

• Conveyor type (belt conveyor or mold-chain conveyor) — chassis and index synchronization are fixed at manufacture.
• Mold format (175 × 275 mm or 205 × 600 mm) — frame sizing fixed at manufacture and not changeable in the field.
• Inclusion capability and target throughput — inclusion handling restricts model choice.

Model selection (conveyor type × mold format — base model)

• Belt conveyor / 175 × 275 mm: NGOSD10CV — max 500 g/shot, 4.2 kW; accepts inclusions ≤ 2 mm (filling path only).
• Belt conveyor / 205 × 600 mm: NGOSD20CV — max 1000 g/shot, 5 kW; inclusion-free.
• Mold-chain conveyor / 175 × 275 mm: NGOSD36CV — max 700 g/shot, 4.2 kW; inclusion-free.
• Mold-chain conveyor / 205 × 600 mm: NGOSD60CV — max 1200 g/shot, 5 kW; inclusion-free.

Elimination criteria and cycle-rate notes

• Machine mechanical cycle up to 20 shots/min on inclusion-free product; actual production rate depends on shot weight, suction timing, pouring speed and conveyor indexing.
• With maximum inclusions (NGOSD10CV) expect roughly 5–7 shots/min under heavy-inclusion conditions.
• Eliminate models whose mold format, required shot weight, or inclusion capability exceed limits; follow format/conveyor substitution rules to select alternatives.

Configuration options (availability and consequence if omitted)

• Z-axis motion (servo) — available on all models; omitted = fixed head height.
• Hopper level sensors — available on all models; omitted = manual hopper monitoring.
• Heated three-way bypass valves at hopper feeds — available on all models; omitted = no automatic bypass diversion.
• Heated FDA-approved flexible food hose — available; omitted = unheated line risks chocolate cooling before hopper.

One-shot head architecture and controls

• Common-valve (CV) architecture: two piston banks (chocolate outer annulus and filling inner bore) stroke in parallel into an engraved aluminum manifold plate feeding one concentric nozzle per cavity.
• Shell-to-filling ratio set by piston stroke and stored in PLC recipes; recipe change requires no hardware modifications.
• PID-controlled dry heating of manifold, depositor body and three-way valves plus cold-start protection prevents dosing until working temperature is reached.
• Servo-driven suction (suck-back) on both banks and servo-driven pouring/dosing ensure repeatable stroke control and stable shell-to-filling ratio.

Belt vs chain conveyor — mounting constraint

• NGOSD10CV and NGOSD20CV mount to a cooling-tunnel belt and deposit into belt-mounted molds; NGOSD20CV can also serve as a deposit unit on a drop line.
• NGOSD36CV and NGOSD60CV mount to a mold-chain conveyor and deposit into molds indexed on a mold chain inside a molding line.
• Conveyor type is fixed at manufacture; changing it post-delivery requires a new chassis.

Stand-alone depositor vs bundled molding line

• This product covers the stand-alone depositor (depositor only; no cooling tunnel, no demolding included).
• Bundled compact or full molding lines (including cooling and demolding) are separate configurations available when required.

Common features (all models)

• Construction: AISI 304 stainless steel, engineering plastics and aluminum.
• Two heated hoppers with pneumatic agitators included as standard.
• Common-valve timing mechanism with one valve per side synchronizing its pistons.
• HMI for dosing, shell-to-filling ratio, temperatures, Z-axis (if fitted), suck-back, conveyor sync and recipe storage.
• 6 bar compressed air required for hopper agitators and pneumatic pistons when Z-axis option is fitted.
• Rigid C-frame chassis for retrofit into existing lines; 380 V three-phase supply.

Models summary and highlights

• NGOSD10CV — belt, 175 × 275 mm molds; 10+10 pistons feeding 10 concentric nozzles; max 500 g/shot; inclusions ≤ 2 mm via filling path only; up to 20 shots/min (≈5–7 with max inclusions); 4.2 kW.
• NGOSD20CV — belt, 205 × 600 mm molds; 20+20 pistons; max 1000 g/shot; inclusion-free; can be used on drop lines; 5 kW.
• NGOSD36CV — mold-chain, 175 × 275 mm indexed molds; 36+36 pistons; max 700 g/shot; inclusion-free; 4.2 kW.
• NGOSD60CV — mold-chain, 205 × 600 mm indexed molds; 60+60 pistons; max 1200 g/shot; inclusion-free; 5 kW.

Position in the production line

• Typical upstream chain: chocolate storage tank → tempering machine → NGOSD-CV depositor → cooling tunnel → demolding station or manual demolding.
• Tempering machine and upstream supply must sustain the planned shot weight and cycle rate; on chain models supply must be continuous.

Warranty and lead time

• Standard warranty: 1 year against manufacturing defects.
• Lead time: typically 3–4 months from order because chassis size, piston geometry, mold or belt mounting and conveyor interface are sized at manufacture.
