SJYB-Ⅶ 3–12L Heavy-Duty Automatic Bulk Liquid Packaging Machine

1. Product Overview

The SJYB-Ⅶ is an industrial-grade, heavy-duty Vertical Form Fill Seal (VFFS) liquid packaging machinery specifically designed for large-scale bulk packaging ranging from 3L to 12L. Engineered to handle heavy load capacities with maximum stability, this single-lane, back-sealing (center sealing) system is optimized for thick, multi-layer laminated (composite) films. It delivers the extreme structural strength, high barrier properties, and superior oxygen isolation required to transport and store bulk fluids safely without leaking.

The system completely automates the entire manufacturing loop—from extra-wide roll film bag forming, precision volumetric or flow-meter dosing, and heavy-flow liquid filling, to reinforced thermal sealing, cold cutting, synchronized date coding, mark detection, and batch counting. Operating at a stable capacity of up to 9 bags/minute, the SJYB-Ⅶ provides a rugged, high-precision turnkey solution for bulk dairy, oils, sauces, and chemical manufacturers worldwide.

3. Technical Features

• Reinforced Multi-Blade Heavy-Load Sealing: Specifically calibrated to handle the intense hydraulic stress of up to 12L 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 weld strength on heavy laminated films. A safety interlock triggers an alarm and halts filling 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 specifications changeover between different bulk pouch sizes.

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

  1. Pneumatic Cut-off Valve + Float Switch Loop: Maintains an ultra-stable 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 extra-wide film pulling network is driven and monitored by a high-torque servo motor to guarantee silky-smooth web tension under heavy 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 reducer, and industrial pneumatic cylinders to ensure smooth and stable 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.

• 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-Ⅶ ensure seal security for extra-large packages up to 12L?

A: Packaging 3L to 12L of liquid generates massive kinetic impact during drop tests and shipping. To prevent bursts, the SJYB-Ⅶ utilizes a specialized multi-seal-blade design backed by reinforced heavy-duty pneumatic cylinders and PID thermal management. This delivers an ultra-wide, multi-layered fused weld across thick laminated films, providing the heavy-duty packaging strength and oxygen barrier required for secure industrial bulk transport.

Q2: What is the benefit of choosing the Flow Meter filling configuration for bulk quantities?

A: When handling large bulk changes (e.g., shifting from a 5L batch up to a 12L batch), the Flow Meter + Supply Pump configuration allows operators to type the exact volume directly into the HMI touch screen. This completely eliminates manual mechanical adjustments, slashes changeover downtime down to seconds, and maintains an exceptionally strict dosing accuracy of ±0.5%.

Q3: What type of packaging film does this machine require, and what sizes can it produce?

A: The SJYB-Ⅶ is built exclusively for multi-layer laminated (composite) films with an extra-wide roll capacity supporting film widths from 590mm to 810mm. Thanks to the horizontal sealing unit’s 洛 stepless height adjustment system, your team can flexibly tune pouch lengths to create a variety of bulk specifications within the 3–12 Liter spectrum.

Q4: Can this 12L heavy-duty filler handle viscous products like paste, puree, or heavy oils?

A: Yes, absolutely. While the standard pneumatic cut-off valve setup handles free-flowing bulk fluids perfectly, you can easily integrate our optional servo rotor pump. This positive-displacement configuration effortlessly pushes high-viscosity pastes and thick sauces through the 316L stainless steel manifold into the bulk pouches without air pockets or dripping.

Q5: Is the fluid system easy to clean according to food-grade standards?

A: Yes. To comply with rigorous international food-safety and chemical safety criteria, the entire fluid pipeline and balance tank are crafted from medical-grade SUS316L stainless steel, which is highly resistant to corrosive cleaners, acids, and alkalis. The manifold is CIP-ready, docking directly with your factory’s automated cleaning loop for hands-free flushing.
