Continuous enrobing and tempering machine EM200TT

for chocolatestainless steel

Overview
The EM200 series Chocolate Enrobing Belt is a curtain-coating conveyor for pre-formed, flat-bottom centres. It applies tempered chocolate or compound coatings via a continuous falling curtain while a roller or trough beneath the 200 mm stainless-steel wire-mesh belt coats the underside. Excess coating drains through the mesh to the reservoir. The enrober is designed to be used between a tempering unit and a cooling tunnel; if either tempering or cooling is absent, specify a complete enrobing line (ENL200) instead.

Process suitability

• Suitable for pre-formed, flat-based products (bars, biscuits, wafers, slabs of fondant/marzipan, dried fruit) that travel flat on a wire-mesh belt.
• Not suitable for small, free-flowing round centres requiring all-round coating (use a coating pan) or for bulk loose centres (use a belt coater or pan designed for loose product).
• Real chocolate must be delivered tempered from an upstream temperer; the enrober does not temper or cool the coating.

Mounting height: first decision
Both EM200 models share a 200 mm wire-mesh belt and 0.55 kW drive; they differ in frame height to match temperer outlet. Bench-height temperer → EM200TT (tabletop frame). Floor-standing or continuous temperer → EM200 (floor frame).

What a chocolate enrober does
The enrober carries centres on a stainless-steel mesh belt under a falling curtain of coating; a roller or trough beneath the mesh applies underside coating. An air blower and vibration section remove excess and level the surface. A tail-cutting (detailer) rod trims the strand before pieces transfer to a cooling tunnel. The enrober itself does not temper or cool the coating.

Design and operating principles of the EM200 enrobing belt
The system is built around an AISI 304 stainless-steel wire-mesh conveyor. Excess coating drains through the mesh and returns by gravity to the reservoir. A rotating disc and scraper lift coating to the trough. Bottoming is achieved via a plate or trough under the mesh and an adjustable roller to set underside pickup. Finishing elements (air blower, vibration section, detailer rod) allow mechanical tuning of coating behaviour without changing line layout.

Enrober vs coating pan vs molding (selection)

• Enrober (EM200TT / EM200): for pre-formed, firm, flat-based centres; one-pass curtain coats top/sides and a roller/trough coats the bottom — use when a flat-based finish is required.
• Coating pan: for small, robust, free-flowing centres (nuts, raisins, dragees); builds up thin layers by tumbling — use when an all-round shell or multilayer build-up is required.
• Molding line: for shaped solid or shell pieces formed in moulds; deposits tempered chocolate into moulds and cools — use when no separate centre is present.

Selection by installed equipment (summary)

• Tempering machine + cooling tunnel installed → EM200 or EM200TT matched to temperer outlet height.
• Tempering only → EM200 or EM200TT plus a cooling tunnel (without a tunnel coating will not set correctly).
• Cooling tunnel only → add a tempering machine plus matching enrober.
• Neither installed → choose the complete ENL200 line (tempering + 200 mm enrober + cooling tunnel).

Coating control: what each element does (summary)

• Chocolate temper & viscosity — controls coverage, gloss and set; set upstream by temperer and formulation.
• Air blower — controls top/side thickness and bubble removal; adjust blower output with belt speed.
• Vibration section — removes excess and evens bottom coverage; adjust intensity to avoid surface marks.
• Bottoming roller/trough — sets underside thickness via adjustable gap under the mesh.
• Detailer rod — trims tails and ensures clean transfer; position relative to transfer spacing is critical.
• Belt speed — sets throughput and residence time; increase blower output proportionally with speed.
