SJYB-ⅢSD Automatic Double-Head Liquid Pouch Machine

1. Product Overview

The SJYB-ⅢSD is a high-speed, fully automatic Vertical Form Fill Seal (VFFS) packaging line featuring dual-head filling technology and an optional Class 100 clean environment. Engineered for high-throughput and ultra-hygienic operations, it is the ideal solution for packaging a wide range of fluids and semi-fluids, including pasteurized milk, dairy beverages, pre-fermented yogurt, fruit juices, protein drinks, purified water, soy sauce, vinegar, and various sauces.

The system seamlessly automates the entire production cycle—from roll film bag forming, precise volumetric metering, and filling, to sealing, cutting, date coding, registration mark detection, and final pouch counting. Delivering an impressive output of up to 8,000 bags/hour, the SJYB-ⅢSD ensures pinpoint dosing accuracy and perfectly sealed, retail-ready packaging.

3. Technical Features

• Class 100 Clean Laminar Flow Hood (Optional): The packaging zone is fully enclosed and protected by a Class 100 positive-pressure purified air system, ensuring the entire forming and filling process occurs in an ultra-clean, contamination-free environment.

• Advanced Heat Sealing System: Utilizing intelligent PID temperature control, the machine employs a constant heat sealing and cutting method. If the sealing jaw temperature deviates beyond the normal range (±5°C), the system triggers an automatic alarm and halts the filling sequence immediately to prevent waste.

• Smart Control Interface: Fully integrated PLC architecture combined with an intuitive HMI touch screen interface for simplified operations and real-time monitoring.

• Precision Date Coding: Equipped with a high-definition ribbon printer, featuring an automated ribbon-shortage alarm to prevent uncoded products from leaving the line.

• Servo-Driven Film Feeding: The film pulling system is driven and monitored by an advanced servo system, ensuring silky-smooth web tension. It includes a film-outage alarm and an external web-guiding device for precise alignment.

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

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

• UV Film Sterilization: Integrated high-intensity UV lamps sterilize the packaging film prior to forming. An intelligent safety interlock automatically shuts off the UV light if the chamber door is opened, protecting operators from eye injury.

• CIP Automatic Cleaning Ready: Fully supports Clean-In-Place (CIP) automatic circulation. The machine can seamlessly interface with the client’s existing central CIP infrastructure for effortless sanitation.

• Precise Registration Mark Detection: A premium photoelectric sensor reads eye-marks on the film in real time, controlling the servo motor and cylinder synchronization to guarantee pinpoint bag-length accuracy and flawless pattern alignment.

• Independent Dual-Lane Control (A & B Positions): Lanes A and B feature independent production control units, allowing operators to configure separate packaging parameters for maximum operational flexibility.

• Rigorous Hygienic Standards: Structural components are manufactured from premium SUS304 stainless steel. All product-contact components and feed piping are constructed from medical-grade SUS316L stainless steel, offering superior corrosion, acid, alkali, and absorption resistance.

• Automated Batch Counting: Live production counts are accurately tracked and displayed directly on the main HMI touch screen.

• Utility Access: 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 aseptic requirements)

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

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

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

• Flexible Lane Configurations (Available in single-head filling or dual-head filling setups)

• Fully Customized Tooling & Engineering Tailored to Your Factory Layout

5. Product FAQ

Q1: What range of liquid viscosities and products can the SJYB-ⅢSD handle?

A: The SJYB-ⅢSD is engineered for high versatility, handling both low-viscosity fluids and semi-fluid pastes. It is widely used for dairy products (pasteurized milk, yogurt, dairy drinks), beverages (fruit juice, protein drinks, water), and condiments (soy sauce, vinegar, sauces). For highly viscous materials, we recommend pairing the machine with our optional servo rotor pump to ensure smooth product feeding and flawless dosing accuracy.

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

A: Unlike traditional multi-lane machines that share a single control system, the SJYB-ⅢSD features independent production control units for Position A and Position B. This allows you to configure, adjust, or run separate packaging parameters for each lane on the HMI touch screen. It maximizes your operational flexibility, minimizes downtime during maintenance, and achieves a combined high-speed output of up to 8,000 bags/hour.

Q3: Can this machine meet strict aseptic and hygienic standards for dairy or food packaging?

A: Yes, absolutely. The SJYB-ⅢSD is built to premium sanitary standards. All product-contact piping and parts are constructed from medical-grade SUS316L stainless steel (acid, alkali, and corrosion-resistant), and it fully supports integration with your factory’s CIP automatic circulation cleaning system. For strict aseptic requirements, you can opt for our Class 100 Clean Laminar Flow Hood, which creates a positive-pressure, ultra-clean environment to protect the product during the entire bag-making and filling process.

Q4: What type of packaging film does this machine use, and how is the bag length controlled?

A: This machine is optimized for standard PE (Polyethylene) roll film with a maximum width of 240–350mm, producing a sleek, reliable back-sealed (center-sealed) pouch. To ensure brand consistency and beautiful packaging, the machine utilizes a premium photoelectric sensor for registration mark detection (eye-mark), which works in synchronization with the servo-driven film feeding system to control bag length precisely down to the millimeter.

Q5: Does Saide customize the voltage and language interface for international global markets?

A: Yes. While our standard configuration is AC 220V/50Hz with an English/Chinese HMI, we provide fully customized engineering for global power grids (such as 110V, 380V, or 480V at 50Hz/60Hz) and multi-language touch screen interfaces tailored to your operators’ local language habits.
