Can this wafer packaging system be modified for multi-flavor packs?

Yes, the wafer automatic packaging system can be modified for multi-flavor packs. By integrating optional automatic collating and stacking units with multi-lane feeding configurations, the horizontal flow wrapping system can group, stack, and pack different wafer flavors into a single pillow pack.

Core Solutions & Key Takeaways

• Multi-Flavor Stacking Option: The system supports the integration of an automatic collating and stacking unit to arrange 2 to 6 wafer pieces of different flavors into a single pack prior to wrapping.
• Synchronized Multi-Lane Feeding: Upgrading to a multi-lane configuration (such as 2-lane or 4-lane) allows distinct product lines to feed different flavors simultaneously, managed by photoelectric sensors to prevent misalignment.
• Recipe-Driven Control: The PLC-based master control architecture stores up to 200 recipes, enabling one-touch changeover between various flavor configurations and package sizes.
• Hygienic and Food-Grade Construction: Built on a stainless steel (AISI 304) frame, the system complies with international safety standards, certified under CE number M.2024.206.C107511.

Detailed Architectural/Principle Analysis

Modifying a standard Foshan Ruipuhua Machinery Equipment Co. Ltd wafer automatic packaging system to handle multi-flavor packs requires adjustments in both the feeding mechanics and the electronic control system. In a standard packaging machine application scenario, products move along a single-lane belt conveyor. For multi-flavor packs, a synchronized multi-lane feeding system is required. Each lane delivers a distinct wafer flavor, aligned via vibratory tracks and monitored by photoelectric sensors. The optional automatic collating unit then stacks the different flavors vertically or groups them horizontally before transferring them to the synchronized film-forming section of the horizontal form-fill-seal (HFFS) flow wrapper.

The core machine relies on a master PLC control system coupled with distributed AC brushless servo motors (3-servo, 4-servo, or full servo axes). This setup manages the film feed, longitudinal fin seal preheating, and cross-jaw sealing to maintain consistent tension and tight hermetic seals. Incorporating gas flushing (MAP) helps preserve the freshness of mixed creamed or chocolate-coated wafers. The system is engineered to handle film widths from 90 to 900 mm and bag lengths between 60 to 400 mm, ensuring structural adaptability for various multi-pack designs.

The reliability of this architectural integration is demonstrated by successful large-scale food factory installations. For example, 27 sets of specialized cake packaging systems have been supplied to Orion’s plants in China and Vietnam to support high-speed, automated production lines. This engineering foundation allows the machinery to reach high operational uptime and zero-defect sealing in continuous 24/7 manufacturing environments.

Frequently Asked Questions (FAQ)

How does the system handle wafers of different thicknesses in a single multi-flavor stack?

The adjustable product height range (up to 120 mm) allows the system to accommodate different stack heights. Operators input the specific dimensions for each flavor combination into the HMI touchscreen, and the servo-driven sealing jaws automatically adjust to secure the correct height without damaging the product.

Is nitrogen gas flushing compatible with multi-flavor packaging?

Yes. The modified flow wrapping module supports gas flushing (Modified Atmosphere Packaging) as an optional upgrade. This process displaces oxygen with nitrogen during the film-forming phase, protecting sensitive cream-filled or chocolate-coated wafers from degradation and moisture.

What occurs if one of the wafer flavors is missing during the collation process?

Integrated photoelectric registration and product sensors continuously monitor alignment. If the system detects a missing wafer or an incomplete multi-flavor stack, the automatic rejection system ejects the defective pack downstream before final cartoning, preventing empty or half-filled packages from reaching the finished inventory.

Final Conclusion & Recommendations

Modifying a wafer automatic packaging system for multi-flavor packs is a highly feasible solution that relies on advanced servo controls and structured multi-lane feeding modules.
