The major components of an enrobing line are a bottomer, coater and cooling tunnel. The bottomer (also called pre-bottomer) applies coating to the bottom of the center and cools it on a moving belt. The coater section may have inboard or outboard tempering systems and additional tanks. It coats all sides of the center, including the bottom once again. Some can half coat or stripe the product. The cooling tunnel properly cools the coating being used and a finished product emerges from the end.

A typical chocolate enrobing plant consists of 3 major components- the holding tank, the temperer, and the enrober itself.  The holding tank is where the chocolate is stored, the temperer is where the chocolate is heated to the proper temperature and consistency, and the enrober is where the chocolate is actually coated onto the product.  There are other auxiliary parts in an enrobing plant, including the various pumps used to transfer the chocolate between components, and a cooling tunnel and vibrating tunnel which are used to post-process the product after enrobing.

The components you need will depend on the production throughput you require, as determined by the number of pieces per hour you need to coat. That count will help you determine the tempering capacity you need, the width and speed of the enrober belt, and whether you need other components, such as a melting and a tunnel.

But in general all you need are:

1) A source of tempered chocolate (or heated compound)
2) The enrober belt itself

Depending on the manufacturer, the bottomer (or pre-bottomer) may be built into the enrober belt or it may be a separate piece of equipment that sits in-line.

Depending on the amount of chocolate (or compound) you need on an hourly basis, you may want a melting tank (or some other source of melted chocolate or compound). These can be manual or they can be tanks with integrated pumps and sensors that keep the bowl of the tempering machine full for non-stop, high volume production.

Depending on the amount of production you need to do, you may need a cooling tunnel to reach your production requirements. My experience indicates that it's not hard to do up to 1000 pieces/hour without a cooling tunnel - depending, of course, on what those pieces actually are.
