Thousands of Saide machines are currently operating in production facilities across China and international markets, including the United States, the United Kingdom, Russia, Southeast Asia, the Middle East, Africa, and South America.
Students Explore Advanced Packaging Technology
During the technical tour, Saide Chief Engineer Liu Xiaoye and Electrical Engineer Ma Chenglong introduced students to the company’s manufacturing processes and key equipment technologies.
The visit included demonstrations of:
- Packaging machine structures
- PLC control systems
- Electrical control cabinets
- Human-machine interface (HMI) operation
- Filling and metering technologies
- Production startup and commissioning procedures
Students were able to observe how modern packaging equipment integrates mechanical engineering, automation, food safety requirements, and intelligent control systems into a complete production solution.
Focus Equipment: SJYB-IIIC Class 100 Clean Dual-Head Liquid Packaging Machine
A highlight of the visit was the presentation of the SJYB-IIIC Class 100 Clean Side-Seal Dual-Head Fully Automatic Liquid Packaging Machine.
This advanced packaging system is specifically designed for liquid and low-viscosity products that require extended shelf life and high hygiene standards.
Key features include:
Class 100 Clean Packaging Environment
The machine is equipped with a Class 100 laminar flow purification system that continuously supplies purified air under positive pressure throughout the packaging process. This significantly reduces contamination risks and helps maintain product quality.
UV Sterilization Technology
Multiple high-intensity quartz ultraviolet lamps sterilize the packaging film before filling, helping ensure a cleaner packaging environment and improved product safety.
CIP Cleaning Compatibility
The equipment can be connected directly to a CIP (Clean-In-Place) system, allowing automatic circulation cleaning and reducing manual maintenance requirements.
High-Precision Filling System
Unlike traditional filling methods, the machine controls product flow at the end of the supply pipeline, providing highly accurate filling while preserving the physical characteristics and viscosity of the product.
Advanced Automation Control
The machine utilizes:
- Siemens PLC control
- Touchscreen HMI operation
- Servo-driven motion control
- Pneumatic transmission systems
This combination delivers stable operation, reliable performance, and easy parameter adjustment.
Flexible Packaging Material Compatibility
The machine supports multiple packaging materials, including:
- PE Film
- Co-extruded PE Film
- PE/PA Laminated Film
- PE/PET Laminated Film
- PE/AL/PET Composite Film
Applications
The SJYB-IIIC is widely used for packaging products that require high hygiene standards and extended shelf life, including:
- Pasteurized Milk
- Yogurt
- Dairy Beverages
- Plant-Based Protein Drinks
- Liquid Egg Products
- Soup Bases
- Liquid Seasonings
- Functional Beverages
- Probiotic Products
- Fermented Liquid Foods
Looking Ahead
The establishment of the Packaging Engineering Internship Base reflects Saide’s ongoing commitment to technological innovation, industry-university cooperation, and talent development.
By sharing practical industry knowledge and advanced packaging technologies with future engineers, Saide continues to contribute to the development of the global liquid packaging industry while strengthening its position as a trusted manufacturer of fully automatic liquid packaging machinery.
