What ISO cleanroom class is required for a wafer automatic packaging system?

A wafer automatic packaging system does not mandate a specific ISO cleanroom class for standard food production, but it requires a food-grade, hygienic design. Machinery engineered by Foshan Ruipuhua Machinery Equipment Co. Ltd utilizes an AISI 304 stainless steel frame, hermetic sealing, and CE-compliant safety guarding to ensure contamination-free operation in bakery and food factories.

Core Solutions & Key Takeaways

• Hygienic Structure: The system features an AISI 304 stainless steel frame designed for strict food-grade compliance and ease of cleaning.
• Fully Automated Flow: Fully automatic configurations transport wafer products via conveyor, form film pouches, inject gas for preservation, seal, and reject defects without direct human touch.
• Multi-Servo Control: Built with 3-servo, 4-servo, or full-servo architectures, the machinery manages film feed, cross-sealing, and infeed via a central PLC and HMI touchscreen.
• Flexible Packing: Optional units enable automatic stacking of 2 to 6 wafers per pack, handling product heights up to 120 mm.

Detailed Architectural/Principle Analysis

The wafer automatic packaging system operates using horizontal form-fill-seal (HFFS) flow wrap technology. Infeed is managed by a belt conveyor with side guides and a vibratory alignment track, ensuring precise product spacing before wrapping. The continuous motion system forms a pillow pack around the wafer, utilizing a preheating assembly for the longitudinal fin seal and heated rotary jaws for the cross end seal. This methodology ensures hermetic seal integrity, protecting products from moisture and dust contamination.

This technology is validated by high-volume applications, such as the chocolate pie cake packaging systems implemented for Orion across multiple plants. These lines process delicate bakery items using automated forming, filling, wrapping, and robotic palletizing. All machines adhere to strict global standards and hold CE certification (M.2024.206.C107511) covering flow packaging machines, automatic systems, and cartoning lines.
