Why Hydrocolloid Gelling Physics Dictates Jelly Machine Design
Unlike gummy candies that are deposited into starch/silicone molds before packaging, commercial snack jellies, konjac/collagen strips, fruit cups, and drinking jellies are dosed as hot liquid hydrocolloid sols (72–85 °C) directly into the primary stick, cup, or pouch—setting into an elastic gel only after hermetic heat sealing and cooling! If hopper or manifold temperature drops below the carrageenan/agar/konjac setting threshold (~45–58 °C) during a 10-minute film change, the entire dosing pump gels solid.
Purpose-built jelly packing machines integrate double-wall heated agitated hoppers, SUS316L anti-drip servo pistons, splash-free indexing, and pasteurization-grade sealing jaws across sticks, cups, tubes, and secondary multipacks.

Hot-Fill Jelly Engineering Notes
- Heated Jacketed Hopper & Circulation Loop: PID water/thermal-oil jackets hold carrageenan/konjac syrup at
75–85 °Cwith slow scraper mixing so sugar acid-hydrolysis and premature gelling are both avoided. - Dual-Fill Fruit + Liquid Synchronization: Jelly cup lines drop measured nata de coco, mandarin segments, or konjac pearls at Station 2 before topping off hot clear syrup at Station 3.
- Pasteurization-Proof Seal Integrity: Retort-capable CPP/mLLDPE inner sealant layers survive
85–95 °Chot-water pasteurization baths and cold quench tunnels without delamination.
