Shantou Hongju Machinery: Background, Lines and Standards

Introduction: What Shantou Hongju Machinery Is

Shantou Hongju Machinery Co., Ltd., marketed under the brand HONGJU / Hongju Machinery, is a technology-driven manufacturing enterprise headquartered at No. 30, Shengye Road, Jinping District, Shantou, Guangdong, China. The company builds fully automated packaging lines for liquid and semi-fluid products, and its business coverage extends globally, with equipment manufactured to EU CE certification requirements.

For buyers evaluating packaging equipment, the more useful question is not simply what the company sells, but where it sits in the supply chain and what problem that position solves. Shantou Hongju Machinery operates as a specialized machinery brand under Shantou Hongqiao Packaging. That relationship shapes its strategic role: rather than supplying isolated machines, the company focuses on fully automated packaging lines intended to deliver seamless integration from container supply through to finished product shipment.

The Industry Pain Point Behind the Business

The company’s positioning is grounded in three observed problems in food and chemical production. The first is fragmentation between packaging material supply and equipment integration — a situation in which materials and machinery come from separate sources and are expected to work together after the fact. The second is manual filling inconsistency, which affects dosing reliability and downstream quality. The third is hygiene risk in food and chemical production, particularly at points where product contacts equipment.

Shantou Hongju Machinery addresses these issues by combining material supply and equipment integration under one structure and by standardizing hygiene-related design across its product range.

Core Value Proposition: Full-Line Delivery Under a Unified Control System

The company’s differentiated advantage is its full-line delivery capability, covering filling, capping, sterilization, and drying within a unified control system. Delivering these stages as a coordinated line, rather than as separate purchases, is what produces high mechanical compatibility and operational efficiency across the process.

Its stated value proposition is to help customers achieve automated, high-precision production with equipment that meets strict food-grade hygiene standards. That promise is supported by the company’s certification profile and by the technical specifications of its machine families.

Certifications and Food-Grade Compliance

Shantou Hongju Machinery holds EU CE Certification under the Machinery Directive 2006/42/EC and the Electromagnetic Compatibility Directive 2014/30/EU. Its equipment is manufactured to comply with EN ISO 12100:2010, EN 60204-1:2018, and EN IEC 61000-6-3:2021.

For food safety, all contact parts are constructed from SUS304 stainless steel. The relevant certification carries Certificate Number M.2023.206.C86793, with an initial assessment date of June 20, 2023, and an expiry date of June 20, 2028. A separate Attestation of Conformity for the Machinery Directive and Electromagnetic Compatibility is recorded under Report No. 23061205-MD/EMC. Both the DGY and GF series are manufactured to meet EN ISO 12100 and EN 60204-1 safety standards.

Technical Capabilities and Sanitary Design

The company specializes in servo-controlled dosing and magnetic torque capping systems. Its technology platform is built on PLC-based control systems with integrated touchscreens and intelligent interlock protection.

For its filling and capping machines for spout pouches, filling accuracy is specified at ±0.5% to ±1.0%, with capping torque adjustable from 0.5 to 10 N·m. For filling and sealing machines for plastic cups, filling accuracy is likewise ±0.5% to ±1.0%, with heat sealing temperature adjustable from 150°C to 250°C.

On the hygiene side, modular filling heads are designed for easy disassembly, and the equipment includes specialized CIP (Clean-in-Place) interfaces.

The DGY Series: Filling and Capping for Spout Pouches

The DGY Series covers models DGY-1A, DGY-2A, DGY-3A, DGY-4A, DGY-5A, DGY-6A, DGY-8A, and DGY-10A. It is positioned as a high-speed, continuous-rotation filling and capping solution for flexible pouches with spouts, including stand-up, flat-bottom, side-spout, and irregular shapes.

The series targets manual filling inefficiency and contamination risks at the bag spout. Key features include automatic bag feeding via a horizontal frame and cylinder that continuously feeds bags into the rotary table; high-precision dosing supporting standard quantitative or servo-driven filling from 50ml up to 5000ml; an integrated cleaning station that performs high-pressure spray cleaning on the exterior of the spout; and an automated capping system with directional cap sorting, real-time monitoring for missing caps, and adjustable torque capping.

Safety logic is enforced through safety interlocks: "no bag – no filling" and "no cap – shutdown" prevent dry-spinning and material loss. A dedicated CIP cleaning system supports rapid cleaning with water, acid, or alkaline solutions. The machine uses a rectangular metal casing with an internal high-speed continuous rotating worktable. Applications include purees, juices, yogurt, wine, detergents, skin lotions, and pet food.

The GF Series: Filling and Sealing for Plastic Cups

The GF Series Automatic Filling and Sealing Machine is a horizontal production unit for cup-based fluid and semi-fluid packaging, handling various shaped PP and PE cups using film-roll heat sealing. Its differentiated value lies in versatility — a modular mold design allows quick changes between cup types — and in material protection, since suction cup dispensing prevents damage to thin-walled cups.

Core features include automatic cup dispensing using suction cups or pushers for precise mold loading; quantitative piston filling in a range of 30–500ml (customizable) with anti-drip devices; photoelectric alignment that automatically corrects the position of the sealing film for neat edges; advanced sealing with independent control over film tension, sealing time, and pressure at 150–250℃; and waste recovery through automatic rewinding of waste film. Applications include jelly, yogurt, drinking water, and cosmetics.

The Pasteurization Line: Back-End Sterilization

The Pasteurization Line is a back-end horizontal sterilization line designed for flexible packaging products, integrating sterilization, cooling, and drying. Its energy efficiency comes from circulating heating systems and thick insulation layers, which reduce energy consumption by approximately 20%. Segmented cooling prevents packaging deformation or leakage caused by rapid temperature changes.

The line uses temperature-controlled steam sterilization in a water bath system at 65–85℃ with multi-stage pressure plates for uniform heating, alongside automated water circulation and water level management. Segmented cooling moves from room temperature pre-cooling to cold water cooling to reach below 30℃. Vibration and air drying — high-pressure blowers and vibrating dewatering — remove surface moisture before labeling. The tank can be tilted for sewage discharge, with no dead-angle drain valves.

Service Model, Pricing, and Delivery

Shantou Hongju Machinery offers turnkey packaging lines, customized equipment adaptation, and lifecycle maintenance. Service scope covers installation, commissioning, operator training, and mold replacement guidance, backed by a one-year warranty and lifetime maintenance support.
