Automated Zongzi Sterilization Line is an advanced, fully automated production line designed for the efficient processing and sterilization of Zongzi, also known as zongzi. This system enhances both productivity and hygiene while maintaining the delicate balance of flavor and texture in the Zongzi. Equipped with high-tech automation, the line offers significant time and labor savings, increasing throughput and ensuring product safety through precise sterilization processes. The line includes features like automatic Zongzi feeding, basket loading, and basket unloading, making it an ideal choice for large-scale production.
Zongzi Sterilization Line

Working Process
The process begins with the automatic loading of Zongzi into sterilization baskets. These baskets are then transferred into the sterilization tank, where hot water is used to disinfect the Zongzi. The automatic flipping system rotates the baskets throughout the sterilization cycle to ensure consistent and uniform exposure to heat. Once sterilized, the baskets are automatically unloaded and cooled, ready for packaging. This fully automatic Zongzi sterilization line minimizes manual handling, increases throughput, and reduces the risk of contamination.
Key Machines
