SYB-IISC High-Speed Side-Seal Dual-Head Fully Automatic Liquid Packaging Machine

1. Product Overview

The SYB-IISC is an industrial-grade, high-speed Dual-Head Fully Automatic Side-Seal Liquid Packaging Machine engineered for the modern dairy, beverage, condiment, and liquid food industries. Designed to handle continuous, high-throughput production at 90–134 bags per minute, this advanced system fully automates the complete packaging process — from film feeding, UV sterilization, and precision metering through to side sealing, cutting, batch coding, and finished bag discharge.

By integrating a modular PLC control architecture with servo-driven and pneumatic actuation, the SYB-IISC achieves consistent, high-precision filling at a metering accuracy of ±0.5–1% while accommodating a flexible fill range of 50–1,000 ml per bag. Supporting a wide product portfolio including pasteurized milk, fruit juice, soy milk, drinking water, plant-based beverages, sauces, edible oils, lubricants, and liquid detergents, it seamlessly interfaces with upstream processing lines to deliver a continuous, hygienic, and highly stable output — making it the premier turnkey solution for high-throughput liquid packaging operations.

3. Four Core Advantages

• UV Inline Sterilization System: Equipped with an integrated UV sterilization unit positioned directly along the film travel path. This system continuously irradiates the inner film surface prior to filling, eliminating surface microbial contamination and ensuring that every sealed bag meets stringent hygienic standards for dairy and food-grade liquid packaging.

• Modular PLC Architecture with Touchscreen HMI: Features a fully modular design built on an industrial-grade PLC controller, paired with an intuitive human-machine interface (HMI) touchscreen panel. Operators can manage production parameters, recipe settings, speed control, and fault diagnostics in real time — minimizing changeover time and maximizing operational flexibility across diverse product 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. The system automates the full 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, ensuring contamination-free transitions between product batches and continuous industrial uptime.

4. Technical Workflows & Features

• Servo & Pneumatic Hybrid Actuation: The SYB-IISC 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 ensures stable bag dimensions and consistent seal integrity even at maximum throughput.

• Dual-Head Parallel Filling: The dual-head configuration allows two bags to be formed, filled, and sealed simultaneously in a single machine cycle, effectively doubling throughput relative to single-head designs without increasing the equipment footprint. Each filling head operates independently, enabling precise individual dosing control.

• Inline UV Film Sterilization: Prior to reaching the filling zone, the inner surface of the PE film passes through a UV irradiation chamber. This contactless sterilization step deactivates surface bacteria and molds, extending product shelf life without the need for chemical preservatives or additional aseptic infrastructure.

• Universal Downstream Integration: The SYB-IISC features a universal signal interface framework within its PLC control panel. It communicates directly with upstream liquid supply systems and downstream conveyors or secondary packaging equipment, enabling seamless integration into fully automated production lines across diverse factory environments.

5. Product FAQ

Q1: What liquid product types is the SYB-IISC compatible with?

A: The SYB-IISC is engineered for a broad spectrum of liquid and semi-liquid products. Its standard configuration is compatible with pasteurized milk, fruit juice, soy milk, drinking water, plant-based beverages, soy sauce, vinegar, edible oils, lubricants, liquid detergents, and liquid cosmetics — making it one of the most versatile side-seal liquid packaging platforms available for multi-category production facilities.

Q2: How does the machine maintain metering accuracy at high speeds?

A: Achieving ±0.5–1% dosing precision at up to 134 bags per minute requires tightly coordinated volumetric control. The SYB-IISC handles this through its PLC-governed servo and pneumatic actuation loop, which continuously cross-references bag count, fill timing, and volumetric flow. This real-time feedback system compensates for minor viscosity fluctuations and supply pressure variations, ensuring that every bag receives a consistent, on-spec fill volume from the first bag to the last.

Q3: How does the UV sterilization system protect product hygiene?

A: The inline UV irradiation unit is mounted along the film path upstream of the filling zone. As the PE film unwinds and travels toward the bag-forming station, the inner surface is continuously exposed to germicidal UV-C light. This eliminates surface bacteria, molds, and yeasts that may be present on the packaging material, creating a hygienic barrier at the point of fill — a critical safeguard for dairy and short-shelf-life beverage products.

Q4: How does the CIP system work, and how long does a cleaning cycle take?

A: Cross-contamination control is essential for multi-product facilities. The SYB-IISC is designed with full CIP (Clean-In-Place) automatic circuit flushing compatibility. All internal fluid channels are engineered with smooth sanitary finishes and zero dead-end geometry. When connected to your facility’s central CIP loop, the system runs automated rinse, wash, and sanitize cycles without requiring manual component teardown — dramatically reducing changeover time between different product categories and ensuring regulatory compliance for food-contact hygiene standards.

Q5: Can the SYB-IISC be integrated into an existing automated production line?

A: Yes, absolutely. The SYB-IISC is built as an open-architecture packaging platform. Its PLC control unit supports standard industrial signal protocols, allowing it to receive start/stop commands, speed synchronization signals, and fault interlocks from upstream liquid supply tanks, homogenizers, or pasteurizers, as well as downstream conveyors and case-packing equipment. This makes it straightforward to incorporate the SYB-IISC into both greenfield line builds and the upgrade of existing packaging infrastructure.
