Jelly Bean Polishing Tech: How to Maintain Glaze Shine in Auto-Packaging

Learn how LeChao Bonbons uses advanced panning and climate control to maintain a mirror-like jelly bean glaze during high-speed packaging and global shipping.

On candy shelves, the glossiness of jelly beans directly correlates with consumers’ perception of the product’s “freshness” and “high quality.” For global buyers, the real challenge isn’t making a brilliant finished product, but ensuring that these jelly beans maintain that perfect “mirror glaze” even after the impact of high-speed automated packaging lines and temperature fluctuations during long-distance sea shipping.

The Core of the Coating Process: Rotary Coating Technology

The gloss of jelly beans doesn’t come from spraying, but from precisely controlled rotary coating (panning).

• Sub-coating Stage: Sugar powder and syrup are coated onto the jelly bean core to create a uniform surface.
• Polishing Stage: Food-grade carnauba wax or beeswax is added to the rotating pan.
• Hardness Control: The thickness of the coating layer must be precisely calculated (usually to the micron level) to ensure that it does not crack due to impact in the weighing hopper of the automated packaging machine.

The Challenge of “Gloss Loss” in Automated Packaging

In large-scale production, automated packaging lines are the “natural enemy” of gloss.

• Physical Friction: Vibrating feeders and chutes generate continuous friction. If the coating layer lacks sufficient toughness, it can cause tiny scratches on the surface, significantly reducing gloss.
• Clouding Phenomenon: If the humidity in the production environment is not properly controlled, trace amounts of water inside the finished product will be released after sealing, causing a white haze on the glaze.
• LeChao’s Solution: We use multi-layer stepped polishing technology and maintain a constant low-humidity environment (RH < 45%) in the packaging workshop to ensure that each candy is in the best dry state before being bagged. ## 3. Stability in International Transportation: Key to B2B Procurement

For global distributors, the performance of products within shipping containers is crucial.

1. Anti-sticking properties: By optimizing the melting point parameters of palm wax, we ensure that our jelly beans remain individually separate and do not fuse together, even in environments above [temperature].
2. Anti-oxidation glaze: A special sealing coating isolates the product from air, preventing color fading caused by pigment oxidation.
