What is Electric liquid filling and packaging machine ？

Key Functions and Working Process

1. Container Conveyance: Empty containers are transported to the filling station via a conveyor belt.
2. Positioning and Fixing: Mechanical devices align and secure containers to prevent displacement during filling.
3. Liquid Filling: Liquids are dispensed into containers in precise, pre-set volumes (e.g., milliliters, liters). Filling methods vary based on liquid viscosity (e.g., water, syrup, oil) and include:
   • Gravity filling (for low-viscosity liquids).
   • Pressure filling (for foamy or volatile liquids).
   • Vacuum filling (for thick or viscous liquids).
4. Residue Removal: Some machines clean excess liquid from container mouths to avoid interfering with sealing.
5. Sealing/Capping: Containers are sealed using methods like screw capping, press capping, or heat sealing (for pouches) to prevent leakage or spoilage.
6. Labeling and Coding (Optional): Labels (with branding, ingredients, or expiration dates) are applied, and production details (e.g., batch numbers) are printed.
7. Finished Product Handling: Packaged products are conveyed to the next stage (e.g., cartoning, storage).

Key Features

• High Automation: Reduces manual labor, boosts production speed, and minimizes human errors (e.g., inaccurate filling volumes).
• Adjustability: Parameters like filling volume and speed can be easily modified via control systems (e.g., PLC programming) to accommodate different container sizes and liquid types.
• Hygiene and Safety: Parts in contact with liquids are often made of food-grade or pharmaceutical-grade materials (e.g., stainless steel), ensuring compliance with industry standards (e.g., FDA for food, GMP for pharmaceuticals) and ease of cleaning.
• Versatility: Handles liquids of varying viscosities, corrosiveness, or volatility—from low-viscosity liquids (water, juice) to high-viscosity ones (honey, sauces), and even some particle-containing liquids (with specialized filling nozzles).

Applications

• Food & Beverage: Bottled water, juice, soy sauce, vinegar, cooking oil, sauces.
• Pharmaceuticals: Oral liquids, disinfectants, medical alcohol, pharmaceuticals.
• Cosmetics & Daily Chemicals: Shampoo, laundry detergent, skincare products, cleaning agents.
• Chemicals: Small-packaged lubricants, antifreeze, coatings.
