3. Technical Features

• Precision Side-Sealing & Thermal System: Utilizing intelligent PID temperature control, the system employs a constant heat sealing and mechanical cutting method optimized for PE film. If the sealing head temperature deviates by even ±5°C from the normal threshold, a safety interlock triggers an automatic alarm and halts filling immediately to eliminate material waste.

• Independent Dual-Lane Control (A & B Positions): Lanes A and B feature independent production control units. This unique architecture allows operators to run or configure separate packaging parameters for each lane via the touch screen, maximizing operational flexibility.

• Class 100 Clean Laminar Flow Hood (Optional): The interior filling and forming zone can be fully enclosed and protected by a positive pressure of Class 100 purified air, completing the entire packaging cycle in an ultra-clean environment.

• Smart PLC & HMI Interface: Controlled via a premium integrated PLC architecture and an intuitive HMI touch screen panel, enabling rapid parameter adjustments, real-time tracking, and simple diagnostics.

• Servo-Driven Film Feeding: Powered by an advanced servo system to ensure silky-smooth film feeding and web tension control. Includes an automated film-outage safety alarm and an external web-guiding device for flawless alignment.

• Robust Transmission Main Drive: Synchronized by a high-torque combination of a servo motor, heavy-duty reducer, and pneumatic cylinders to guarantee stable, reliable, and smooth mechanical motion.

• Intelligent Volumetric Filling System: A pneumatic cut-off valve regulates liquid supply into the balance tank, where an automated float switch monitors fluid levels (complete with a low-level safety alarm). Dosing volumes are easily fine-tuned via an adjustable rotary dial, while high-precision cylinders drive the flow control valves.

• High-Definition Date Printing: Equipped with a precision ribbon coding printer featuring an automated ribbon-shortage alarm to prevent uncoded products from moving down the line.

• UV Web Sterilization: Integrated high-intensity UV lamps sterilize the packaging film prior to bag forming. A built-in safety switch automatically deactivates the UV light if the chamber door is opened, protecting operators’ eyes.

• CIP Automatic Cleaning Ready: Fully supports Clean-In-Place (CIP) automatic circulation loops. The machine seamlessly interfaces with your facility’s existing central CIP infrastructure for effortless sanitation.

• Pinpoint Registration Mark Detection: A high-sensitivity photoelectric sensor reads film eye-marks in real time, synchronizing the servo system to guarantee perfect bag-length accuracy and graphics alignment.

• Rigorous Hygienic & Material Standards: All structural frame components are manufactured from premium SUS304 stainless steel. All internal product-contact piping and feed parts are constructed from medical-grade SUS316L stainless steel (acid, alkali, and corrosion-resistant).

• Production Logistics: Live production counts are accurately tracked and displayed directly on the touch screen. Standard configuration includes a built-in air blow gun for daily maintenance and a dedicated electronic scale communication socket.

4. Optional Configurations

• Integrated Class 100 Clean Laminar Flow Hood (Fulfills strict ultra-clean requirements)

• Servo Rotor Pump (Installed post-balance tank on the filling pipeline; highly recommended for high-viscosity pastes and sauces)

• Product Supply Feed Pump (Installed pre-balance tank to automate material transfer from storage; supports automated gravity-feeding configurations if high-level upstream storage tanks are used)

• Multi-Language HMI Touch Screen Interface (Customized to regional language preferences)

• Flexible Configuration Choices (Available in single-head filling or dual-head filling setups)

• Fully Customized Tooling & Engineering Tailored to Your Factory Layout

5. Product FAQ

Q1: What are the main advantages of a side-sealing liquid machine like the SJYB-ⅢSC?

A: The SJYB-ⅢSC features a specialized side-seal configuration, which shifts the sealing seam to the side of the pouch rather than the center back. This design leaves the front and back panels completely clear, offering a larger, uninterrupted surface area for brand graphics, logo printing, and nutritional labels, making it highly popular for retail pasteurized milk and beverage branding.

Q2: How does the independent dual-head (Lanes A & B) system improve factory uptime?

A: Unlike standard multi-lane machines that share a single set of parameters, the SJYB-ⅢSC is built with independent production control units for Position A and Position B. You can adjust the filling volumes, sealing speeds, or specific parameters for each lane independently via the HMI touch screen. If one lane requires a film roll change, the other lane can continue running, preserving factory throughput.

Q3: Can the SJYB-ⅢSC handle high-viscosity products accurately?

A: Yes. The integrated cylinder-driven volumetric filling system achieves exceptional dosing accuracy (±0.5% – 1%) for free-flowing fluids like milk, juices, and water. For thicker, semi-fluid items or dense sauces, we can integrate our optional servo rotor pump behind the balance tank to provide smooth, consistent positive-displacement feeding.

Q4: Does this machine meet international food hygiene and CIP standards?

A: Absolutely. To comply with strict global food safety regulations, the structural frame is built from premium SUS304 stainless steel, while all product-contact piping and feed components are made from medical-grade SUS316L stainless steel (highly acid- and alkali-resistant). Furthermore, the entire fluid pathway is CIP-ready, meaning it hooks up directly to your central CIP system for effortless, teardown-free automated flushing.

Q5: How is the packaging film sterilized during production?

A: To ensure a hygienic packaging process, the machine features an integrated UV lamp film sterilization system that irradiates the packaging film prior to forming. For operator safety, it includes an intelligent interlock switch that automatically shuts off the UV light instantly if the chamber door is opened, preventing any risk of eye injury.
