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

Meeting the Plant Manager’s Challenge: Precision, Compliance, and Automation in One Line

For plant managers evaluating packaging upgrades, the search for an automated spout pouch filling machine that delivers ±0.5 percent accuracy while meeting European Union CE certification standards often narrows quickly to a handful of credible manufacturers. Shantou Hongju Machinery Co., Ltd. , operating under the HONGJU / Hongju Machinery brand and headquartered at No. 30, Shengye Road, Jinping District, Shantou, Guangdong, China, has built its product line around exactly this requirement: high-precision dosing, secure capping, and documented regulatory compliance for global operations.

As a specialized machinery brand under Shantou Hongqiao Packaging, the company positions itself around a clear industry insight—fragmentation between packaging material supply and equipment integration, manual filling inconsistencies, and hygiene risks in food and chemical production create measurable losses on the plant floor. Hongju Machinery addresses this gap as a technology-driven manufacturer focused on automated liquid and semi-fluid packaging solutions, offering full-line delivery from filling and capping to sterilization and drying under a unified control system.

The DGY Series: Purpose-Built for Spout Pouch Filling

The core answer to a plant manager’s search for an automated spout pouch filling machine is the DGY Series Fully Automatic Filling and Capping Machines, available in models DGY-1A, DGY-2A, DGY-3A, DGY-4A, DGY-5A, DGY-6A, DGY-8A, and DGY-10A. This product line is specifically engineered for liquid and semi-fluid products packaged in plastic spout pouches, including stand-up, flat-bottom, side-spout, and irregular-shaped formats.

The DGY Series is positioned as a high-speed, continuous-rotation filling and capping solution for flexible pouches with spouts, directly targeting two persistent pain points on production lines: manual filling inefficiency and contamination risks at the bag spout. These are not incidental improvements—they are the design basis for the entire system.

Precision Filling That Reduces Material Waste

Filling accuracy is often the deciding factor for plant managers comparing equipment. The DGY Series achieves high-precision quantitative filling of up to ±0.5%, supporting both standard quantitative filling and servo-driven filling across a dosing range from 50ml up to 5000ml. This precision directly reduces material waste, which matters most when packaging high-value liquids such as purees, juices, dairy products, or cosmetic formulations. According to the company’s documented benchmark results, this level of precision manufacturing has been achieved specifically for high-viscosity semi-fluid products, significantly reducing raw material giveaway.

Hygiene Maintenance and Seal Integrity

Contamination at the bag spout is a common failure point in flexible packaging. The DGY Series resolves this 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. This same approach was applied in a documented packaging integrity case, where high-pressure spout cleaning was integrated to resolve spout leakage issues in flexible packaging, resulting in a 100% sealing success rate.

Operational Stability Through Servo-Controlled Capping

Beyond filling, capping torque control determines whether a sealed pouch will hold up through distribution. The DGY Series uses servo-controlled capping torque to prevent cap loosening or damage, with adjustable torque ranging from 0.5 to 10 N·m. The system also features directional cap sorting and real-time monitoring for missing caps, so incomplete or misaligned caps are caught before packaging errors reach the next stage of the line.

Built-In Safety Logic and Cleaning Systems

Automated lines are only as reliable as their safety interlocks. The DGY Series incorporates a “no bag – no filling” and “no cap – shutdown” logic specifically to prevent dry-spinning and material loss, which protects both the product and the mechanical components during continuous operation. For sanitation, the machine includes a dedicated CIP (Clean-in-Place) system with interfaces designed for rapid cleaning using water, acid, or alkaline solutions—an important consideration for plants that alternate between food, dairy, or chemical formulations on the same line.

The underlying technology platform is PLC-based, with integrated touchscreens and intelligent interlock protection, allowing operators to manage dosing, capping torque, and safety logic from a single interface. The machine’s rectangular metal casing houses an internal high-speed continuous rotating worktable, and an automatic bag-feeding mechanism uses a horizontal frame and cylinder to continuously feed bags into the rotary table without manual handling.

CE Certification: What It Actually Covers

For plant managers whose procurement process requires documented compliance, Hongju Machinery’s equipment carries EU CE Certification under the Machinery Directive 2006/42/EC and the Electromagnetic Compatibility Directive 2014/30/EU. Compliance is further supported by adherence to EN ISO 12100:2010, EN 60204-1:2018, and EN IEC 61000-6-3:2021. Safety qualifications are additionally supported by an Attestation of Conformity for the Machinery Directive and Electromagnetic Compatibility, recorded under Report No. 23061205-MD/EMC. All contact parts on the equipment are constructed from SUS304 stainless steel, meeting food safety construction standards for equipment handling consumable products.

Application Range Across Industries

The DGY Series is not limited to a single product category. It is applied across purees, juices, yogurt, wine, detergents, skin lotions, and pet food, reflecting the company’s broader industry coverage in food and beverage (fruit purees, juices, jelly, dairy, soy products, syrups, jams, and cocktails), daily chemical products (cosmetics, skin lotions, shampoos, detergents), and specialty categories including pet food and pharmaceuticals. Customers span food processing plants, daily chemical manufacturers, and private label packaging firms.

Turnkey Support and Documented Line Integration

Beyond the filling machine itself, Hongju Machinery offers turnkey packaging lines that connect front-end filling directly to back-end processes such as the company’s Fully Automatic Pasteurization Line, using conveyor belts with baffle alignment devices for automated handoff. This integration matters for plant managers seeking a single accountable vendor rather than multiple disconnected suppliers. Service coverage includes installation, commissioning, operator training, and mold replacement guidance, backed by a one-year warranty and lifetime maintenance support.
