Chocolate on ice cream

FoodJet's chocolate depositor applies tempered chocolate onto ice cream, into moulds or onto products, in the design you choose. The depositing head is an array of small, individually controlled nozzles, so it places chocolate exactly where you want it and varies the amount per section, with no mechanical change-overs. You run different decorations on the same line, and the system keeps the tempered chocolate at the right temperature from supply to nozzle.

Per-nozzle control, not a single shot

A one-shot depositor places the same deposit everywhere on the product. The FoodJet chocolate depositor does not. Its head is an array of small nozzles, each controlled on its own, so you vary the amount of chocolate in each section of a mould or product. That is how you create detailed, personalised tempered chocolate decorations rather than one fixed pattern.

Change the design without changing the line

Seasonal decorations, branded products, or several designs at once: the pattern lives in the software, not in fixed tooling. You switch design with a recipe, so there are no mechanical change-overs and you keep the line running. The per-nozzle control places each decoration the way you defined it.

Decorating extruded ice cream

On an extruded ice cream line, the depositor sits above the conveyor after extrusion, when the products are stable and ready for decoration. It fits over your existing conveyor.

A stationary depositor suits a fixed pattern on a steady product flow. A movable depositor suits a decoration path that needs controlled movement relative to the product. Depending on the finish you want, you deposit tempered chocolate or a compound.

A surface layer instead of dipping

Besides decorations, you can deposit a full surface layer on each ice cream, as an alternative to dipping. You apply chocolate, caramel or a fruit preparation only where it adds value, with less mess around the line.

The depositor sits before or after hardening, depending on your process. Before hardening works when the product position is stable. After hardening suits a fully set product or a sharp edge on the layer. When products shift or rotate on the belt, vision guidance detects each position; for well-aligned products a sensor is often enough.

A controlled, clean process

Working with a high-value material like tempered chocolate, you want to control the whole process: hold the temperature, keep spillage low, and reduce the risk of contamination. The closed system and the per-nozzle dosing keep waste down and the process clean, so more of your chocolate ends up on the product.

Working out your capacity

You can get a solid estimate of your line capacity yourself, with four numbers: the size of your product, the pitch (the spacing between products, across and along the belt), the number of lanes, and the belt speed. Product size, pitch and lanes together decide how many products fit on the belt at any moment. Multiply that by the belt speed and you have your capacity in products per minute, and from there per hour or per shift. This part is straight maths, and you do not need us for it.

There is one factor that does need our input: can we deposit your product accurately at the belt speed you are aiming for? That depends on the material. As a guide, line speeds around 10 m/min have proven possible for hot products like tempered chocolate. Temperature, viscosity and the way the chocolate flows all affect how fast we can dose it cleanly, so treat that figure as a guide for a first estimate, not as a limit. For every application we run a trial with your actual product, so the capacity you plan with is one we have measured, not one we have assumed.

More products on the same belt

The core of a FoodJet system is the depositing head: an array of individually controlled nozzles across the full width of the belt. Each nozzle deposits on demand, so the head places chocolate on any product, anywhere across the belt, with no fixed tooling and no set product positions. Together this means you do not lose belt space to a fixed pitch: you run products closer together and across the full width, so the same belt and the same speed deliver more products per minute. The smaller the product, the more this counts.

A chocolate system built around your line

Every FoodJet system is configured to your line, so no two are identical. A tempered chocolate setup is matched to your product, your design and your throughput, as a standalone unit or integrated into your existing conveyor, with the supply unit as a stand-alone temperature unit. The table below shows what a typical chocolate application looks like.

FAQ

How much capacity can a FoodJet chocolate line handle?

In most cases you can work this out yourself. Your output comes down to four numbers: product size, pitch, number of lanes and belt speed. The first three tell you how densely the products sit on the belt; multiply that by the belt speed and you have your output per minute. The one factor we confirm is whether we can deposit your chocolate accurately at that speed. As a guide, line speeds around 10 m/min have proven possible for tempered chocolate. To be sure, we run a trial with your own product.

Is this a one-shot depositor?

No. The head is an array of small nozzles, each controlled on its own, so you vary the amount of chocolate per section of a mould or product and create detailed, personalised decorations rather than one fixed deposit.

Can I run different chocolate designs on the same line?

Yes. The design lives in the product recipe in software, so you switch between seasonal or branded designs with a recipe upload, with no mechanical change-over.

How does the system keep the chocolate tempered?

FoodJet uses double-jacketed hoses and piping throughout, fed by the FoodJet supply unit, a closed water circuit with its own heat exchanger. From supply to nozzle the chocolate is held at the right temperature.

Can it run inline with my existing line?

Yes. A tempered chocolate setup runs as a standalone unit or integrated into your existing conveyor, configured to your line speed and product layout.

Where does the depositor go on an ice cream line?

Above the conveyor, after extrusion for decorations. For a surface layer it goes before or after hardening, depending on your process and the finish you want.

Every FoodJet system is configured and quoted to fit your line and your requirements.
