Two cereal bars, one with the word ENERGY and one with a zigzag line in white

Decoration on cereal and energy bars

A FoodJet depositor with vision puts a chocolate design on each cereal, granola, energy or protein bar: a word, a name, a logo or a seasonal motif, in chocolate or compound. Vision measures every bar after cutting, so the design follows its position and rotation, and a new design is a recipe, not new tooling.

Why do stringers and enrobers limit bar decoration?

Bars sell on their top. Most lines decorate them with a stringer that draws fixed lines across the belt: the chocolate also lands between the bars and on the belt, and every bar gets the same lines. The other route is dipping or enrobing, which gives a full coat of chocolate with no room for a design.

How does FoodJet put a design on each bar?

A vision system measures the position, rotation and outline of every bar. The FoodJet Control Platform on the industrial PC turns the stored design into a droplet map for that bar, and a heated depositing head with a row of individually controlled nozzles deposits it on the moving belt. The design follows the measured outline of each bar, even when bars sit off-centre or rotated after cutting, and the line keeps running.

Text, logos and seasonal designs from the recipe

ENERGY on one run, a heart or a star the next: a design is a file, not a tool. You can also run a different design per lane, so several products leave the same line.

Chocolate on the bar, not on the belt

Each nozzle opens only where the design needs it, so the chocolate you pay for ends up on your bars. You buy less chocolate, and your line needs less cleaning.

What happens to a bar out of specification?

Vision checks every bar against the limits the operator has set. A bar that is broken or too short gets no chocolate, and its status is passed on to your line, so your reject system knows which bar to take out.

A top layer instead of dipping

Where only the top of the bar shows, you can deposit a full chocolate layer on the top face as an alternative to dipping, with a free rim that follows the shape of each bar. FoodJet deposits from above only, so for a coat all round, an enrober remains the right choice.

Frequently asked questions about bar decoration

Can you write text on a bar?

Yes. A word, a name or a logo in chocolate is a design in the recipe, and it goes on every bar that passes.

Do the bars need to be aligned after cutting?

No. Vision measures each bar, even when it sits off-centre or rotated, and the design turns with it.

Which materials can you use?

Chocolate and compound. We usually work with chocolate compound, and we check your bars and your material in a trial.

How fast can the line run?

Around 10 m/min is normally within easy reach. Above that it depends on your material, so we confirm the speed for your bars in a trial.

Can I test this with my own bars?

Yes. In our test centre we test with your bars and your chocolate or compound. Place your bars at random, as they come off the cutter: you see the designs before you decide. Read how testing and feasibility works.

Test it with your own bars

Send us your bar size and lanes, how the bars arrive after cutting, your chocolate or compound, the designs you want and your line speed. We test it with your own bars. After the trial, we advise on the setup for your line and send you a proposal.
