Biscuit cavity filling with a FoodJet depositor

FoodJet enables cavity filling of biscuits with materials such as jam/marmalade, chocolate, or caramel. For well-aligned products, Design Studio guides the depositing into each cavity. If products shift or rotate, vision guidance detects the position and orientation of each piece to maintain consistent placement. The system can, in most cases, be added to an existing conveyor where line space is available.

Biscuit cavity filling with a FoodJet depositor

Cavity filling deposits a controlled amount of material into each biscuit cavity—creating consistent product appearance and repeatable portioning. With FoodJet, you can fill cavities inline with materials such as jam/marmalade, chocolate or caramel. For stable, well-aligned products, depositing can be guided using Design Studio. If products can shift or rotate, vision guidance can detect position and orientation per piece to keep placement consistent. The system can be integrated on an existing conveyor when line space is available.

What is biscuit cavity filling (and where it fits in your process)

Biscuit cavity filling applies a defined deposit into recessed features of the biscuit to create a filled or topped product without manual handling. The depositor is typically placed after baking and cooling, when products are stable on the conveyor and ready for adding a filling component. Because the deposit is controlled per product, cavity filling supports repeatable portioning and a consistent visual result across batches. The exact setup depends on cavity geometry, conveyor presentation, and material behavior, so depositing parameters are tuned to your product and line.

Aligned products: deposit accurately with Design Studio

If biscuits are well-aligned and presented consistently, Design Studio can be used to guide where deposits land within the cavity pattern. A product design can be uploaded and used to define deposit positions, supporting accurate placement and repeatability. This approach works well when product spacing and orientation are stable and when upstream handling ensures consistent presentation on the conveyor.

Not aligned? Use vision-guided cavity filling

When biscuits can shift, vary in spacing or rotate, vision guidance can detect each product’s position and orientation and adjust depositing accordingly. This helps maintain consistent placement even when perfect alignment upstream is not feasible. The best approach depends on product contrast, cavity visibility and required accuracy.

Materials for cavity filling (jam/marmalade, chocolate, caramel)

FoodJet supports cavity filling with a range of materials. Material suitability depends on viscosity, temperature management, and the required finish. Below are common examples.

• Jam / marmalade (including pectin-based fruit preparations)
• Chocolate / compound
• Caramel

Material note

Material compatibility depends on viscosity and process conditions. Share your material and target result, and we can advise on the most suitable configuration.

Discuss your biscuit cavity filling application

Share your biscuit format, cavity geometry, material and line layout. We’ll advise on depositing setup, placement in the process, and whether Design Studio or vision guidance is recommended for your presentation.
