SJYB-Ⅷ 10–25L Industrial Heavy-Duty Automatic Bulk Liquid Packaging Machine

1. Product Overview

The SJYB-Ⅷ is an ultra-heavy-duty, maximum-capacity Vertical Form Fill Seal (VFFS) liquid packaging machinery specifically engineered for large-scale industrial bulk applications from 10L to 25L. Positioned at the pinnacle of high-volume fluid processing, this robust single-lane, back-sealing (center sealing) system is optimized for extra-thick, multi-layer laminated (composite) films. It delivers the extreme structural integrity, high barrier properties, and uncompromising oxygen isolation required to package, transport, and store massive fluid volumes safely without any risk of bursting or leakage.

The system completely automates the entire industrial manufacturing cycle—from extra-wide film roll bag forming, high-precision volumetric or flow-meter dosing, and heavy-flow liquid filling, to reinforced thermal sealing, cold cutting, synchronized date coding, registration mark detection, and batch counting. Operating at a stable, controlled capacity of up to 6 bags/minute, the SJYB-Ⅷ provides a rugged, premium turnkey solution for large-scale institutional catering, bulk dairy, industrial oils, beverage bases, and liquid chemical manufacturers globally.

3. Technical Features

• Reinforced Multi-Blade Structural Sealing: Specifically calibrated to absorb the massive hydraulic impact and static weight of up to 25L of liquid. Utilizing smart PID temperature control and a constant heat sealing with precise cold cutting method, it features an advanced multi-seal-blade design that drastically enhances the weld matrix on heavy laminated films. A safety interlock triggers an alarm and halts filling instantly if temperatures deviate by ±5°C.

• Stepless Height Adjustability: The heavy-duty horizontal sealing unit permits stepless height adjustments within a designated range, enabling operators to achieve rapid specification changeovers between different industrial bulk pouch sizes.

• Dual-Option High-Precision Filling Systems: Configured precisely to match the physical flow traits of your specific bulk product:

  1. Pneumatic Cut-off Valve + Float Switch Loop: Maintains an ultra-稳定 fluid level inside the balance tank (with low-level alarms) and fine-tunes dosing via a mechanical rotary adjustment knob.

  2. Digital Flow Meter + Supply Pump Loop: Allows operators to adjust and input filling volumes digitally directly on the touch screen interface, paired with a micro-adjustment rotary knob for flow optimization.

• Smart PLC & HMI Interface: Driven by an integrated PLC architecture and an intuitive HMI touch screen panel for centralized parameter editing, real-time statistics monitoring, and simplified troubleshooting.

• High-Torque Servo Film Feeding: The super-wide film pulling network is driven and monitored by a high-torque servo motor to guarantee silky-smooth web tension under extreme loads, complete with an automated film-shortage safety alarm.

• Heavy-Duty Transmission Main Drive: Synchronized by a premium combination of a servo motor, high-ratio industrial reducer, and large-bore pneumatic cylinders to ensure smooth, zero-slippage mechanical transmission during high-mass operations.

• Class 100 Clean Laminar Flow Hood (Optional): The interior processing environment can be fully enclosed and blanketed with a positive pressure of Class 100 purified air to achieve an ultra-clean packaging zone.

• 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 entire internal manifold interfaces seamlessly with your facility’s existing central CIP infrastructure for effortless sanitation.

• Pinpoint Registration Mark Detection: A high-sensitivity photoelectric sensor tracks color marks on the film in real time, synchronizing the servo system to guarantee precise bag length and complete pattern integrity.

• Rigorous Hygienic Standards: 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, offering superior corrosion, acid, alkali, and absorption resistance.

• Logistics & Utilities: Tracks and displays live pouch counts directly on the main HMI screen. Standard configuration includes a built-in air blow gun for daily maintenance and a dedicated electronic scale communication socket.

4. Optional Configurations

• Class 100 Clean Laminar Flow Hood: Creates a positive-pressure, ultra-clean environment inside the machine for strict hygienic processing of bulk liquids.

• Servo Rotor Pump: Positioned on the filling pipeline after the balance tank; highly recommended for handling high-viscosity bulk materials (such as dense pastes, creams, heavy lubricants, or thick sauces).

• Product Supply Feed Pump: Placed before the balance tank to transfer material automatically from your main storage; tailored based on specific product characteristics.

• Multi-Language HMI Touch Screen: Localized operating system interface language customized to your global factory operators’ preferences.

5. Product FAQ

Q1: How does the SJYB-Ⅷ guarantee absolute seal security for extra-large packages up to 25L?

A: A 25L liquid pouch weighs approximately 25kg (55 lbs), which places massive hydraulic stress on film seams during drop testing and bulk shipping. To completely eliminate the risk of bursting, the SJYB-Ⅷ features an advanced multi-seal-blade design backed by a reinforced heavy-duty structural frame and high-pressure pneumatic cylinders. This creates an ultra-wide, deeply fused multi-layered weld across thick laminated barrier films, ensuring elite seam strength.

Q2: What filling system is recommended for switching between 10L and 25L batches?

A: We highly recommend the Flow Meter + Supply Pump configuration for large-scale changes. Instead of manually adjusting mechanical knobs, your operators can simply type the target volume (e.g., 10,000ml to 25,000ml) directly into the HMI touch screen. The digital system handles the rest automatically, maintaining a strict dosing accuracy of ±0.5% while slashing changeover downtime.

Q3: What type of packaging film and width does this machine support?

A: The SJYB-Ⅷ is engineered exclusively for heavy-duty, multi-layer laminated (composite) films capable of holding high weight capacities. It supports super-wide web widths ranging from 810mm to 970mm. Thanks to the stepless height adjustment on the horizontal sealing unit, bag lengths can be finely tuned to accommodate different bulk volume specs within the 10–25L spectrum.

Q4: Can this machine be integrated into a “Bag-in-Box” (BIB) production line?

A: Yes, absolutely. The SJYB-Ⅷ is the primary heavy-duty vertical machine used to manufacture the internal high-barrier liquid bags for industrial Bag-in-Box (BIB) and catering supply chains. The filled, sealed, and counted pouches can easily be directed onto a conveyor line for manual or automated boxing.

Q5: Is the fluid pipeline system compatible with aggressive CIP cleaning regimes?

A: Yes. To satisfy rigorous global food-safety and industrial chemical hygiene criteria, the entire balance tank, product manifold, and filling valves are crafted from medical-grade SUS316L stainless steel. This premium material is highly resistant to corrosive sanitizers, acids, and alkalis. The entire manifold is CIP-ready, docking directly with your factory’s automated cleaning loop for hands-free flushing.
