Full Automatic 5L-30L Drum Gallons Net Weight Filling Machine

Net Weight Filling Machine

Applicable Product Categories:
• Lubricants and Automotive Fluids: Engine oil, motor oil, brake fluid, coolant, transmission fluid, and other petroleum-based or synthetic lubricants
• Edible Oils: Sunflower oil, corn oil, soybean oil, olive oil, and other food-grade vegetable oils
• Agrochemicals and Industrial Chemicals: Pesticides, herbicides, fungicides, liquid fertilizers, and industrial chemical solutions
• Food and Beverage Liquids: Soy sauce, vinegar, cooking wine, salad dressings, and other non-carbonated, low-viscosity food-grade liquids

Filling Capacity Range: 5 L to 30 L

• The weighing and filling machine features a primary structural frame fabricated from 304 stainless steel, while all product-contact components-including the submersible nozzle, fill manifold, and transition hoppers-are manufactured from 316 stainless steel to ensure long-term resistance to chloride-induced corrosion and full compliance with hygiene requirements.
• Process control is executed by a certified industrial PLC, interfaced with a ruggedized touchscreen HMI that supports real-time parameter monitoring, recipe management, and audit-trail-enabled operation.
• The submersible nozzle employs depth-controlled immersion and flow-rate modulation to suppress foam generation and eliminate entrained air during liquid transfer-critical for maintaining fill consistency in low-surface-tension fluids.
• Each filling head incorporates a dedicated, temperature-compensated load cell mounted in direct mechanical alignment beneath the fill station, enabling real-time gravimetric feedback and achieving ±0.2% repeatability across the specified 5 kg–30 kg net-weight range.
• The fully modular architecture allows tool-free disassembly of wetted sections within ≤15 minutes, supporting CIP-compatible cleaning protocols and meeting GMP-aligned maintenance intervals.
• Comprehensive diagnostics continuously monitor sensor integrity, actuator response, and weight signal stability; deviations exceeding predefined thresholds automatically initiate an audible alarm, contextualized on-screen alert, and controlled process halt to prevent nonconforming batches. This design enables robust, validated performance across heterogeneous packaging formats-from narrow-neck HDPE bottles to wide-mouth stainless-steel pails-without recalibration or hardware modification.

The net weight filling machine is used for filling liquid in a range of 5 to 25kg. The weighing filling machine comprises a bucket feed conveyor, a bucket positioning mechanism, a bucket push mechanism, a dual-stage (fast/slow) filling system, a feeding transition hopper, a precision weighing controller, and a programmable logic controller (PLC). Designed for high-accuracy automated liquid dispensing, this system accommodates both non-foaming and foaming liquids, ensuring reliable performance across diverse fluid properties.
