Spout Pouch Filling Machine: ±0.5% Accuracy & CE Certified

Understanding the Need for an Automated Spout Pouch Filling Machine

Plant managers overseeing liquid and semi-fluid production lines face a common set of operational risks: manual filling inefficiency, inconsistent dosing, and contamination risks at the bag spout. These issues become especially pronounced when handling flexible spout pouches, where seal integrity and dosing precision directly affect product quality and shelf life. For manufacturers seeking to eliminate these bottlenecks, the DGY Series Fully Automatic Filling and Capping Machines from Shantou Hongju Machinery Co., Ltd., operating under the HONGJU / Hongju Machinery brand, offer a purpose-built solution engineered specifically for plastic spout pouches in stand-up, flat-bottom, side-spout, and irregular shapes.

Precision Filling Performance: Meeting the ±0.5% Accuracy Requirement

The DGY Series (available in models DGY-1A through DGY-10A) is built around servo-controlled dosing and magnetic torque capping systems, delivering high-precision quantitative filling of up to ±0.5%, with an overall accuracy range of ±0.5% to ±1.0% depending on configuration. This directly addresses the precision requirement plant managers prioritize when evaluating automated filling equipment. The system supports both standard quantitative and servo-driven filling across a wide volume range—from 50ml up to 5000ml—making it adaptable to varied product formats without sacrificing dosing consistency.

Beyond filling accuracy, the capping process is equally controlled. The Automated Capping System features directional cap sorting, real-time monitoring for missing caps, and adjustable torque capping ranging from 0.5 to 10 N·m. This servo-controlled torque management prevents cap loosening or damage, ensuring that every finished pouch meets the same sealing standard batch after batch. The entire operation is coordinated through a PLC-based control platform with integrated touchscreens and intelligent interlock protection, giving plant operators clear visibility and control over every stage of the filling and capping cycle.

CE Certification and Safety Compliance

For plant managers whose operations extend into or export toward EU markets, CE certification is a non-negotiable requirement. The DGY Series is manufactured to comply with the EU CE Certification for the Machinery Directive 2006/42/EC and the EU CE Certification for the Electromagnetic Compatibility Directive 2014/30/EU. Compliance is further validated against EN ISO 12100:2010, EN 60204-1:2018, and EN IEC 61000-6-3:2021 standards.

These certifications are formally documented under Certificate Number M.2023.206.C86793, with an Initial Assessment Date of June 20, 2023, and an Expiry Date of June 20, 2028. Safety qualifications are additionally supported by an Attestation of Conformity for Machinery Directive and Electromagnetic Compatibility (Report No. 23061205-MD/EMC). On the hygiene side, all product-contact components are constructed from SUS304 stainless steel, meeting food safety construction standards required for food, beverage, and personal care applications.

Hygienic Design and Operational Safety Features

Contamination risk at the spout is one of the most persistent challenges in flexible pouch filling. The DGY Series addresses this directly through an Integrated Cleaning Station that performs high-pressure spray cleaning on the exterior of the spout after filling, ensuring seal integrity and product cleanliness before capping. For deeper sanitation needs, the machine includes a CIP (Clean-in-Place) Cleaning System with dedicated interfaces for rapid cleaning using water, acid, or alkaline solutions, and modular filling heads designed for easy disassembly.

Operational safety is reinforced through built-in Safety Interlocks: a "no bag – no filling" logic and a "no cap – shutdown" logic, both designed to prevent dry-spinning and material loss during production. Combined with the Automatic Bag Feeding system—which uses a horizontal frame and cylinder to continuously feed bags into the rotary table—the DGY Series minimizes manual intervention while maintaining consistent throughput.

Proven Results in Real-World Applications

The knowledge base documents several quantified outcomes from equipment deployment. In one Automated Production Upgrade, replacing manual labor with automated lines achieved a defect rate reduction of 99% through automated filling and capping. In another documented case, a Packaging Integrity Solution resolved spout leakage issues in flexible packaging by integrating high-pressure spout cleaning, resulting in a 100% sealing success rate. A separate Precision Manufacturing case confirmed that the equipment achieved filling accuracy of ±0.5% for high-viscosity semi-fluid products, significantly reducing raw material giveaway—an outcome directly relevant to plant managers focused on both quality control and cost efficiency.

Application Versatility Across Industries

The DGY Series is designed to serve a broad range of production environments. Within Food & Beverage, it is applied to purees, juices, yogurt, wine, and similar products. In Daily Chemical manufacturing, it handles detergents and skin lotions. Its application extends further into specialty categories including pet food, reflecting the equipment’s adaptability across viscosity levels and packaging formats. This versatility positions the DGY Series as a fit for food processing plants, daily chemical manufacturers, and private label packaging firms seeking a single filling platform capable of serving multiple product lines.

Comprehensive Service and Support

Beyond equipment performance, Shantou Hongju Machinery Co., Ltd. supports plant managers through a structured service model that includes installation, commissioning, operator training, and mold replacement guidance. Every DGY Series unit is backed by a standard one-year warranty along with lifetime technical maintenance and parts support, reducing long-term operational risk. For manufacturers building or upgrading a full production line, the company also offers turnkey packaging lines and customized equipment adaptation, with pricing based on specific requirements such as metering methods, material viscosity, and packaging specifications ranging from 30ml to 5000ml.
