How Does a Chocolate Coating Machine Work?

Ideally, the working principle of a typical chocolate coating equipment takes effect in different stages along the production line.

You’ll find out that comparatively large equipment for commercial chocolate coating often comes as a complete chocolate coating system.

Relatively smaller machines designed for small-scale production may come in separate components and be integrated to form a single unit.

Even so, the working principle tends to be somewhat the same since it involves the basic principles across all models.

Here is a step by step process of how this equipment works;

  1. All the necessary chocolate raw materials and ingredients are introduced into the tempering system. This allows the materials to melt and turn into a smooth liquid formulation.

Tempering system is connected with the coating machine to supply liquid chocolate formulation at the coating stage.

  1. The melted liquid chocolate formulation goes through a wire rack, which carries it to via the prebottomer for consistent coating.

Wire rack takes the formulation towards the chocolate coating device and easing its passage through a preliminary cooling conveyor. And this is fundamental since it expedites solidification of liquid chocolate formulation applied by the prebottomer.

  1. The solidified formulation goes through the conveyor for transportation towards the coating pump and forms a continuous waterfall-like curtain.

This curtain covers the respective set surface of the product. Through the aid of coating pumps, the actual coating process takes place at this stage.

  1. Chocolate liquid formulation failing to get on the item drains back through the wire rack. Depending on the specific model of chocolate coating machine you are using, some allow the ingredients to return to the tempering unit.

Some machines also have blowers, which perform a similar function making sure chocolate never pools on the product.

  1. Immediately the product leaves the coating pump, it goes straight to the vibrating table.

Essentially, the wire rack vibrates dynamically to ensure the chocolate ingredient formulation coats the products evenly.

  1. The coated product then moves to the de-tailing rod. The essence of this rod is merely to cut or remove excess or unwanted chocolate ingredient pieces.
  1. Chocolate-coated products are then transferred to wax paper to make it easy to remove them immediately they cool down.

Typically, they pass through an elongated cooling, and insulated tunnel operated at a constant low temperature. This makes it yield a shiny, hard-finish product with a relatively optimized shelf-life.

That’s primarily how a typical chocolate coating machine works.
