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.
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.
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.
Tempered chocolate only works if it stays at the right temperature through the whole system. FoodJet uses double-jacketed hoses and piping throughout, fed by the FoodJet PUL supply system, a closed water circuit with its own heat exchanger that runs as a stand-alone unit. From supply to nozzle, the chocolate is held at temperature, so the deposit stays consistent across the run.
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.
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.
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.
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 PUL supply system as a stand-alone temperature unit. The table below shows what a typical chocolate application looks like.
Application | Depositing tempered chocolate onto ice cream, into moulds or onto products |
Materials | Tempered chocolate and comparable high-value materials |
Substrates | Ice cream, moulds, products |
Pattern | Per-section design, defined in software, amount varies per nozzle |
Temperature control | Double-jacketed hoses and piping, fed by the FoodJet PUL closed water circuit |
Design changes | Recipe upload, no mechanical change-overs |
Conveyor width | Configured to your line, for example a standard 800 mm belt |
Line speed | Around 10 m/min for tempered chocolate, confirmed in a trial |
System | Standalone or integrated; PUL supply as stand-alone temperature unit |
See how FoodJet's chocolate depositor precisely applies tempered chocolate patterns on ice cream bars, consistent, at production speed, and without contamination. The closed-loop system ensures zero product contact with the environment between runs.
