To fill and seal chocolate paste in cups, you need a hygienic and accurate filling and sealing process using a specialized cup filling machine. Chocolate paste is viscous, so the filling system must be designed for semi-liquid or thick pastes like chocolate spread, or ganache.
Step-by-Step Process to Fill and Seal Chocolate Paste in Cups:
1. Cup Feeding
Cups (plastic, paper, or aluminum) are automatically dropped into the machine via a cup denester.
Cups are typically made of PP, PET, or laminated materials.
2. Chocolate Paste Filling
A servo-driven piston filler or heated hopper system is used to fill the chocolate paste into the cup.
If the chocolate paste is thick or requires heating:
Use a jacketed hopper with temperature control (around 40–60°C) to maintain flowability.
Filling volume can be customized (20g–500g or more per cup).
3. Lid Placement
You can choose from two options:
Pre-cut foil lids: Automatically placed on top of the filled cups.
Roll film: Automatically unwound, cut, and placed over cups.
4. Heat Sealing
A heat sealing station applies pressure and temperature to seal the cup with foil or film.
Common seal types:
Aluminum foil heat seal
PET/PE film seal
Optional: add easy-peel design for consumer convenience
5. Coding (Optional)
Use inkjet or thermal printer to apply production/expiry date and batch number.
6. Cup Discharge & Packing
Sealed cups are discharged onto a conveyor for:
Shrink-wrapping
Tray packing
Cartoning
✅ Recommended Machine Type:
Rotary Cup Filling Sealing Machine for medium output
Inline Cup Filling Sealing Machine for higher output and multiple filling lanes
