Automatic Liquid Filling Machine

(Guangzhou Shilong Machinery Equipment Co., Ltd. – A Professional Manufacturer in China with 18 Years of Expertise in Packaging Equipment)

The Shilong Fully Automatic Liquid Filling Machine is an intelligent automated liquid dispensing system produced directly in our factory. It integrates automatic bottle arranging, precise quantitative filling, anti-drip suction, automatic conveying, no-bottle-no-fill protection, and fault alarms.

Powered by core metering technologies such as servo pistons, flow meters, or negative pressure, and equipped with a Siemens PLC + Touch Screen control system, all product-contact parts are made of 304/316L food-grade stainless steel. It is compatible with liquids of low, medium, and high viscosity, as well as those containing micro-bubbles or corrosive properties. The machine can operate as a standalone unit or seamlessly integrate with capping, labeling, coding, and check-weighing equipment to form a complete automatic packaging line. As a reliable supplier, Shilong meets the large-scale, standardized, and hygienic production needs of the food, daily chemical, pharmaceutical, and chemical industries.

Core Product Features

1. Ultra-High Precision, Stable & Drip-Free

Driven by servo motors (piston/flow meter metering), achieving a standard accuracy of ±0.5%, with high-end models reaching ±0.2%. Long-term operation shows a precision decay of ≤0.12% over 12 hours.

Filling nozzles feature an anti-drip suction device to eliminate stringing, dripping, and material waste, keeping the production line clean.

Dual calibration mechanism (Touch screen parameters + Physical weight correction) ensures consistent fill volume.

2. Intelligent Control & Quick Changeover

Siemens PLC + 7-inch Color Touch Screen: One-touch setting for fill volume, speed, and counting. Stores 100+ production recipes, allowing specification changes without complex debugging.

Quick-change structure: Bottle/capacity changeover takes under 3 minutes, compatible with round, square, irregular, and wide-mouth bottles.

Intelligent Protection: No-bottle-no-fill, stop on no material, overload/leakage alarms, and self-diagnostic fault codes to reduce waste and downtime risks.

3. Hygienic, Durable & Easy to Clean

All material-contact parts use 304/316L Stainless Steel + Food-grade Silicone/PTFE seals, complying with GMP, QS, and food contact standards. Corrosion-resistant, non-leaching, and easy to clean.

Modular quick-release piping supports CIP (Clean-in-Place) or offline disassembly cleaning, ensuring no dead angles or residue, suitable for multi-product switching.

Stable machine structure with an MTBF (Mean Time Between Failures) ≥800 hours. Core components are manufactured in-house for superior durability.

4. High Efficiency & Flexibility

Filling Range: 10ml–5L (customizable up to 200L drums). Available in 4–16 head linear models with a capacity of 1000–6000 bottles/hour, customizable to meet specific speed requirements.

Material Compatibility: Low viscosity (water, alcohol, beverages), medium viscosity (oil, laundry detergent), high viscosity (honey, syrup), micro-bubbles (juice, vinegar), and weak corrosion (disinfectants, reagents).

High Expandability: Can connect with bottle unscramblers, washers, cappers, labelers, coders, and case packers for a one-stop line solution, reducing multi-supplier coordination costs.

5. Customization & After-Sales Support

Supports non-standard customization: Explosion-proof, anti-corrosion, constant temperature, vacuum filling, and models dedicated to large drums/IBC totes.

Factory Direct Sales: 2-year whole machine warranty (including wearing parts), lifetime maintenance, rapid response in Guangzhou, providing installation, commissioning, operation training, and remote assistance.

Frequently Asked Questions (FAQ) - Exclusive to Shilong

Q1: Can Shilong filling machines handle viscous or foamy liquids?

A: Yes. The standard servo piston type is suitable for viscosities ranging from 1–100,000cP (oil, honey, pastes). For foaming materials (juice, vinegar, wine), we can customize negative pressure/vacuum filling to suppress foam, prevent overflow, and improve accuracy.

Q2: What is the actual filling accuracy? Will it become inaccurate over time?

A: Standard models offer ±0.5% accuracy, while high-end servo models achieve ±0.2%. The accuracy decay is ≤0.12% after 12 hours of continuous operation, outperforming the industry average. A simple monthly calibration (one-touch on screen + weight check) ensures long-term stability.

Q3: How long does it take to change bottle types or volumes? Is it complicated?

A: It takes under 3 minutes without dismantling complex parts: simply adjust parameters on the touch screen, fine-tune the guide rails, and swap the filling nozzle. With 100+ recipe storage, it supports rapid switching for multiple SKUs, ideal for flexible production.

Q4: Is it easy to clean? Will there be residue or cross-contamination?

A: The piping, tanks, and nozzles feature a full quick-release design, cleanable with water or disinfectant. For perishable or high-hygiene materials, CIP (Clean-in-Place) is available, ensuring no dead angles or residue, meeting food/pharmaceutical standards.

Q5: Does it require a specialized operator? How long does it take for a beginner to learn?

A: One person can manage the machine, and independent operation can be mastered after 1 day of training. The touch screen features a user-friendly interface, simple parameter settings, and fault code prompts, requiring no professional electrical or mechanical background.

Q6: What is the warranty period? How is after-sales service guaranteed?

A: We offer a 2-year warranty for the whole machine (including seals, nozzles, and other wearing parts) and lifetime maintenance at cost. As a Guangzhou local factory, we provide 48-hour on-site service, rapid remote troubleshooting, and in-house core component supply for short repair cycles.

Q7: Can it integrate with my existing capping/labeling machines?

A: Yes. Designed with standard interfaces, it is compatible with mainstream brands of cappers, labelers, coders, and conveyors. We provide integration solutions and debugging to quickly form a complete production line.
