3. Four Core Advantages

• Standard-Fit Class 100 Clean Purification System: Unlike competitive models where cleanroom purification is an add-on option, the SJYB-IIISC ships with a top-mounted Class 100 laminar flow purification unit as standard equipment. This system continuously delivers positive-pressure HEPA-filtered sterile air over the film feeding and filling zones, ensuring every packaging cycle is completed in a cleanroom-grade environment — a critical baseline requirement for ESL pasteurized milk, yogurt, and premium flavored dairy products.

• High-Speed Dual-Head Side-Seal Architecture: The side-seal dual-head configuration enables simultaneous forming, filling, and sealing of two bags per machine cycle at up to 134 bags per minute — one of the highest throughput rates available in the cleanroom-grade liquid packaging category. The side-seal structure is optimized for the PE film used across standard dairy pouch formats, delivering consistent seal geometry and bag presentation across all supported SKUs.

• Elite Metering Accuracy & Full-Process Automation: Delivers exceptional dosing precision with a metering accuracy of ±0.5–1%, ensuring consistent fill weights across every bag at full production speed. The system automates the complete packaging sequence — including film drawing, bag forming, liquid filling, side sealing, cutting, and date printing — eliminating manual intervention and reducing labor dependency at every stage of the line.

• CIP-Ready Hygienic Design for Rapid Changeovers: Engineered with full CIP (Clean-In-Place) automatic circuit flushing compatibility. All fluid-contact pathways feature smooth-radius sanitary bends and polished internal surfaces to eliminate hygienic dead zones. When connected to your facility’s CIP loop, the system undergoes automated chemical cleaning and sanitizing cycles without requiring manual component teardown — ensuring contamination-free transitions between different dairy product variants and continuous industrial uptime.

4. Technical Workflows & Features

• Integrated Class 100 Positive-Pressure Air Curtain: The standard-fit top-mounted Class 100 laminar flow unit draws factory air through a multi-stage HEPA filtration system and delivers a continuous downward-flowing sterile air curtain over all film-contact and product-contact surfaces. This positive-pressure design actively repels ambient airborne microorganisms rather than simply filtering the immediate zone — providing a consistently sterile microenvironment that persists even during brief line stoppages or operator access events.

• Inline UV Film Sterilization: As the PE film unwinds and travels toward the bag-forming station, the inner surface passes through a dedicated UV-C irradiation chamber. This contactless sterilization step eliminates surface bacteria, molds, and yeasts on the packaging material before it contacts the product, providing a secondary hygienic barrier that works in tandem with the Class 100 air curtain for comprehensive dual-layer contamination control.

• Servo & Pneumatic Hybrid Actuation: The SJYB-IIISC combines servo motor-driven film transport with pneumatic sealing and cutting mechanisms, delivering synchronized high-speed operation with minimized mechanical wear. This hybrid actuation architecture maintains stable bag dimensions, consistent side-seal geometry, and precise fill volumes even at maximum rated throughput — ensuring uniform finished bag quality across extended production runs.

• Universal Line Integration via PLC Signal Framework: The SJYB-IIISC PLC control unit supports standard industrial signal protocols, enabling bidirectional communication with upstream pasteurizers, homogenizers, and liquid supply tanks, as well as downstream conveyors and secondary packaging equipment. This open-architecture design allows the machine to be embedded into both new greenfield dairy lines and the upgrade of existing packaging infrastructure with minimal integration engineering.

5. Product FAQ

Q1: How does the SJYB-IIISC differ from the SJYB-IIISD, and when should I choose one over the other?

A: The primary distinction is the sealing orientation and throughput profile. The SJYB-IIISC uses a side-seal configuration, which is optimized for standard PE film dairy pouches and delivers a higher maximum throughput of up to 134 bags per minute — making it the preferred choice for high-volume pasteurized milk, flavored milk, and yogurt drink operations where speed is the dominant requirement. The SJYB-IIISD uses a back-seal configuration, which provides greater bag rigidity and is better suited for larger fill volumes or products where pouch structural integrity is a priority. Both models ship with the Class 100 cleanroom purification system as standard.

Q2: Why is the Class 100 purification system standard on the SJYB-IIISC rather than optional?

A: The SJYB-IIISC is specifically positioned for the premium ESL dairy market — pasteurized milk, yogurt, and flavored dairy beverages — where regulatory hygiene standards and consumer shelf-life expectations are the highest in the liquid food packaging sector. Including the Class 100 laminar flow purification unit as standard equipment ensures that every machine delivered to a dairy facility meets cleanroom-grade contamination control requirements from day one, without requiring customers to specify or budget for an upgrade. This also eliminates the risk of a facility operating below its hygiene standard due to an oversight during machine procurement.

Q3: What dairy product types is the SJYB-IIISC optimized for?

A: The SJYB-IIISC is purpose-built for the full spectrum of premium and functional dairy beverages, including pasteurized milk, yogurt drinks, fresh milk, rice milk, oat milk, coffee dairy beverages, fermented milk drinks, and other dairy-based liquid products. Its Class 100 cleanroom environment and dual UV-plus-purification hygiene architecture specifically address the contamination sensitivity of these products, while the high-speed dual-head side-seal system delivers the throughput needed for high-volume dairy production schedules.

Q4: How do the Class 100 purification and UV sterilization systems work together?

A: The two systems target different contamination vectors and operate simultaneously as a dual-barrier hygiene architecture. The inline UV-C irradiation chamber addresses surface contamination already present on the packaging film — bacteria, molds, and yeasts that may have settled on the film roll during storage or handling. The Class 100 laminar flow purification system addresses airborne contamination in the filling environment — continuously flushing the film feeding zone, nozzle area, and open bag mouth with positive-pressure sterile air that prevents new airborne microorganisms from settling on either the film or the product during the filling cycle. Together, they provide comprehensive protection at both the material and environmental contamination pathways.

Q5: Can the SJYB-IIISC maintain its rated throughput while the Class 100 system is active?

A: Yes. The Class 100 laminar flow purification unit operates as an independent parallel system that runs continuously without interfering with the mechanical packaging cycle. The purification airflow is engineered to be stable and non-turbulent — a laminar, downward-flowing curtain that does not disturb film tension, bag forming geometry, or seal jaw alignment at any point during high-speed operation. The machine’s rated capacity of 90–134 bags per minute is achieved and validated with the Class 100 system fully active, not in a purification-off test condition.
