Chocolate Coating Pan Machine

Can coating pans run both chocolate panning and sugar syrup coating?

Yes. All CP models run both processes. The two behave differently in the pan. Chocolate panning relies on cocoa butter crystallization and needs cool dehumidified process air. Sugar syrup coating depends on the coating method — hard panning requires controlled drying and evaporation; soft panning may use cold processing and limited drying air.

What products cannot be coated in a pan?

Coating pans require free-flowing centers that tumble as the pan rotates. Unsuitable products and their correct machine:

• Sticky masses, soft fillings, partially molten products: need a depositor or an enrober.
• Flat products, slabs, bars: need a chocolate enrober with a flat conveyor.
• Products needing single-pass curtain coating: need an enrober, not a pan.

Do coating pans require cool process air?

Only for chocolate panning. Chocolate panning relies on cocoa butter crystallization and requires cool dehumidified process air — either from a climate-controlled room, from an external chiller and air cooler, or from CP1000INTCOOL's built-in cooling. Sugar syrup coating does not require cool air; warm dry air drives hard panning, and soft panning may use cold or limited drying air.

What does the preglazing stage do in chocolate panning?

Preglazing seals the center surface before chocolate is applied. A thin syrup layer is applied while the product rolls in the pan. The purpose is to limit oil migration from nut-based centers into the chocolate layer, reducing softening and fat bloom risk. Syrup is dosed in small portions; controlled process air dries each application before the next. Syrup viscosity is tuned with gum arabic; partial glucose syrup addition limits crystallization. For high-moisture or sticky centers (preserved fruits, soft confectionery centers), dry dusting powders are applied between syrup layers to stabilize the surface and keep rolling uniform. Preglazing may be reduced or omitted on thin target coatings — but skipping it on nut-based centers increases fat bloom and softening risk in the finished chocolate layer.

What happens during the panning (chocolate application) stage?

Panning is the main chocolate coating phase. Chocolate is applied in successive portions while cool dehumidified air is introduced to drive cocoa butter crystallization layer by layer. Airflow direction and volume are tuned to keep distribution even and prevent centers sticking together. Without cool dehumidified process air, shells stay tacky, crystallization slows, and centers stick together — this is the stage that drives the CP1000INTCOOL requirement when conditioned room air is unavailable.

What does the final glazing stage do?

Final glazing sets surface appearance and handling properties. A syrup-based glaze is first applied in multiple thin layers with intermediate drying using reduced-humidity air, until surface tackiness disappears. After a resting period in a controlled environment, a finishing glaze is applied in the same pan. Two categories of finishing glaze are used: wax-based glazes for a protective finish with moderate sheen, and shellac-based glazes for high-gloss surfaces. Parameters adjust by product sensitivity, batch mass, and target surface quality. Skipping the resting period before the finishing glaze produces uneven gloss and surface defects.

What is the difference between a coating pan and a chocolate enrober?

A coating pan builds coating layers on free-flowing centers through repeated tumbling cycles inside a rotating drum. A chocolate enrober coats fixed-shape products in a single continuous pass through a chocolate curtain on a flat conveyor. Pans are for tumbling-suitable centers (nuts, dried fruits, lentils, confectionery centers); enrobers are for slabs, bars, and other flat or fixed-shape products.

What is the difference between CP1000 and CP1000INTCOOL?

Both are 70 kg-class pans. Conditioned-air availability decides:

• CP1000: default for sugar syrup coating, and for chocolate panning when conditioned process air is available from a climate-controlled room or an external chiller and air cooler.
• CP1000INTCOOL: adds built-in air heating and cooling — required for chocolate panning when the room cannot reliably provide cool dehumidified air for cocoa butter crystallization.

What is the difference between hard panning and soft panning?

Both are sugar syrup coating methods:

• Hard panning: thin sugar syrup layers with controlled drying and evaporation between applications, producing a hard crystallized shell.
• Soft panning: concentrated syrups and dusting powders build softer layers, run with cold or limited drying air, with final hardening over time.

Why are ribbed pan interiors used?

Ribbed pan interiors lift and tumble the centers instead of allowing them to slide along the wall. This supports uniform tumbling during chocolate coating, sugar syrup coating, glazing, and polishing cycles. Products that slide instead of tumble become more difficult to coat or polish uniformly. Ribs are fitted on CP400, CP1000, CP1200, and CP1500WTM; CP1000INTCOOL uses an alternative interior design suited to its built-in air-conditioning architecture.

How does the CP1500WTM tilting discharge mechanism work?

CP1500WTM rotates the pan to a controlled angle for discharge, releasing the 220 kg-class batch through gravity instead of manual scooping. The working angle is adjustable. Limit switches prevent mechanical interference and make discharge repeatable across cycles. VFD acceleration and deceleration settings are tuned to reduce shock loads on the gearbox and transmission elements during the tilt cycle. Frame: stainless steel or painted black steel. On smaller manual-discharge models (CP400, CP1000, CP1000INTCOOL, CP1200), discharge is operator-controlled with no tilting mechanism.
