Pneumatic sprayer CPS series

electricstainless steelautomatic

Product overview
The AkayGAM CPS100 is an air-assisted, recipe-driven sprayer that applies filtered liquid chocolate or sugar syrup to centres tumbling in a compatible coating pan. The unit operates immediately upstream of the pan-coating stage and provides repeatable, timed spray pulses from stored recipes. The 100 L reservoir is water-jacketed and PID-heated; product hoses and nozzle assemblies are heated to maintain working temperature to the outlet.

Process suitability — eliminate the sprayer if

• The product contains inclusions or particles > 100 µm (reservoir has no agitator; product must be homogeneous and inclusion-free).
• The product must be processed above 50 °C (maximum product temperature of the machine is 50 °C).
• Chocolate and syrup must alternate without a cleaning stop (product change requires full manual draining, disassembly and cleaning).
• No plant compressed air at 6–8 bar is available, or the coating pan lacks process air for setting/drying (the sprayer does not supply process air).

Coating pan inventory — choose configuration

• Existing coating pans → order CPS100 (sprayer only). Two independent nozzle arms can serve one or two customer CP1000/CP1200 pans.
• No coating pans → order CPS100 + CP1000x2 (complete panning station). One CPS100 with two CP1000 pans (70 L each, 1000 mm diameter) ordered together; blower optional.

Manual ladling vs CPS100 sprayer — key differences

• Manual ladling — requires skilled panner; results vary by operator; hand pouring at 0 bar with no pressure regulation or timer; chocolate typically kept at 40–45 °C in a warming bath.
• CPS100 sprayer — PLC/HMI repeats stored spray ON/OFF timing, operating pressure and reservoir temperature; pneumatic valve and pressure transmitter provide regulated delivery; minimum-level sensor included (no flowmeter or load cell).
• Choose CPS100 when production needs PLC-driven dosing, repeatable batches or one operator managing multiple pans. Keep manual ladling for irregular artisan single-batch runs where capital cost is not justified.

Application by product type — guidance

• Liquid chocolate — use for build-up layers and shell formation; typical reservoir temperature 40–45 °C (dark/milk), untempered; higher air-assist pressure within 4 bar limit may be required depending on viscosity.
• Sugar syrup / gum arabic — use for pre-sealing, finishing layers and polishing; set reservoir temperature per syrup formulation but do not exceed 50 °C; generally atomizes at lower pressure within the 4 bar limit.

How the sprayer works in a coating pan cycle

• Recipe parameters recalled: temperature, pressure, spray duration, waiting time and nozzle selection.
• Short spray steps are repeated while the pan rotates; tumbling distributes coating across the bed of centres.
• Cycles repeat until target coating thickness and finish are reached.

Maintenance and cleaning

• Reservoir water jacket: use 30% food-grade inhibited propylene glycol; untreated water causes scale and reduces heat transfer.
• Nozzles, lines and reservoir: clear product at colour or product changes. For chocolate, never wash with water — purge at working temperature and wipe with warm cocoa butter or a food-grade fat-based cleaner. For sugar syrup, flush with hot water per cleaning recipe.
• Air and control elements: drain and filter compressed-air supply to remove moisture and oil; keep pneumatic valve, pressure transmitter and minimum-level sensor clean.

Warranty and lead time
1-year warranty against manufacturing and construction defects. Typical lead time 3–4 months from order because nozzle-arm configuration and pan bundling are configured at manufacture.

Technical characteristics / specifications
