Chocolate Enrobing Machine

A chocolate enrobing machine — also called a chocolate enrober or chocolate coating machine — covers biscuits, wafers, cookies, and cakes with a smooth, uniform layer of chocolate as they pass on a wire-mesh belt through a flowing chocolate curtain.

Product Overview

The Wanttone chocolate enrobing machine combines a chocolate curtain and bottom-coating system, an air blower that removes excess coating, and a vibrating belt that levels the finish, all built in food-grade SUS304 stainless steel. Paired with a cooling tunnel, it delivers perfectly coated, fully set products at continuous industrial line speed.

Capabilities & Applications

Key Features

  • Uniform Curtain Coating

    A controlled chocolate waterfall coats the top and sides of every product evenly, while the bottoming system covers the underside — full, half, or bottom-only coating as your product requires.

  • Air Blower & Vibrating Wire Belt

    An adjustable blower strips excess chocolate from the surface and a vibrating open-mesh belt levels the coating, giving a clean, glossy finish with consistent coating weight and minimal chocolate waste.

  • Heated, Jacketed Chocolate Circuit

    The enrobing tank, curtain system, and circulation pipework are jacketed and temperature-controlled, keeping chocolate at working viscosity and compatible with upstream tempering units.

  • Cooling Tunnel Integration

    The enrober connects directly to a cooling tunnel that sets the coating under controlled temperature and airflow, locking in gloss and snap before stacking and packaging.

  • SUS304 Hygienic Construction

    A full stainless-steel build with open access, removable chocolate-contact parts, and a fast washdown design meets modern food-safety audit requirements.

  • Line-Speed Synchronization

    Variable-frequency drives synchronize belt speed, curtain flow, and blower intensity with your upstream cooling conveyor and downstream packaging.

  • Widths Configured to Your Line

    Working widths from compact bakery models to full industrial line widths are customized to your product size and capacity.

Applications

  • The chocolate enrobing machine is the heart of any chocolate-coated product line: chocolate-coated biscuits and cookies, enrobed wafers, chocolate-covered cakes and Swiss rolls, coated pretzel sticks and biscuit sticks (Pocky-type), energy bars, and seasonal coated specialties. It integrates seamlessly with Wanttone biscuit production lines, cooling conveyors, chocolate conche refiners, and downstream stacking and packaging equipment.

A Defined Role in the Line

  1. Upstream Requirements

    Confirm the incoming material or product condition, target throughput, infeed height and available utilities.

  2. Core Machine Function

    A controlled chocolate waterfall coats the top and sides of every product evenly, while the bottoming system covers the underside — full, half, or bottom-only coating as your product requires.

  3. Downstream Integration

    Match discharge height, line speed, control signals, guarding and cleaning access with the next operation.

The Wanttone Difference

Chocolate coating is one process where a manufacturer’s practical production experience shows immediately — and Wanttone coats biscuits in its own factory. Our engineers know from daily production how coating temperature, belt speed, blower balance, and cooling profile determine gloss, snap, and coating weight, because we sell chocolate-coated biscuits under our own brand. That producer’s insight is built into every enrober we ship, on top of 40+ years of biscuit equipment engineering since 1981, ISO 9001-controlled manufacturing, and an in-house Foodstuff Machinery Research Institute. Your project includes line layout design, chocolate supply system engineering, on-site installation and commissioning, operator training, and lifetime after-sales service.

Frequently Asked Questions

What products can the chocolate enrobing machine coat?

Biscuits, cookies, wafers, cakes, Swiss rolls, biscuit sticks, pretzel sticks, energy bars, and similar bakery products. Coating style — full, half, or bottom-only — is configured per product.

Do I need a tempering machine with the enrober?

For real cocoa-butter chocolate, yes — proper tempering gives gloss, snap, and bloom resistance. For compound chocolate, simple melting and holding is sufficient. We supply the complete chocolate supply system either way.

How is coating thickness controlled?

Through chocolate curtain flow, belt speed, and blower intensity, all adjustable and storable per recipe. Coating weight is therefore repeatable across shifts.

How does the coating get set before packaging?

The enrober connects to a cooling tunnel sized to your line speed, which sets the chocolate under controlled temperature and airflow before products reach the stacker or packing machine.

Can the enrober be added to my existing biscuit line?

Yes. We customize working width, belt height, and line-speed synchronization to integrate with both new Wanttone lines and existing third-party equipment.
