Condition: excellent (used), BILWINCO 14-Head Multi-Head Weighing Machine – Stainless Steel BILWINCO 14-head multi-head weighing machine, designed for the automatic, precise, and continuous weighing of food products before dosing and packaging. The equipment uses a multi-head combination weighing system that automatically selects the most suitable combination of hoppers to achieve the target weight of each dose. Its 14-head configuration allows for efficient operation in industrial lines that require precision, repeatability, and continuous feeding. Primarily made of stainless steel, this BILWINCO weighing machine is designed for integration with packaging machines, filling machines, and other automatic dosing systems. MAIN FEATURES -Manufacturer: BILWINCO -Type: Multi-head weigher / combination weigher -Number of heads: 14 -Automatic combination weighing system -Dosing controlled by weight -Multiple weighing hoppers -Automatic product distribution -Continuous industrial operation -Construction primarily in stainless steel -Hygienic design for the food industry -Compact configuration for in-line integration -Designed for automatic feeding of packaging machines -Integrable into existing weighing and packaging lines APPLICATION The BILWINCO 14-head multi-head weighing machine is designed to divide the product among different weighing hoppers and automatically calculate the combination that best approximates the programmed weight. Once the combination is selected, the corresponding hoppers discharge the product to form the required dose, which can be transferred directly to a packaging machine, filling machine, or other downstream equipment. This system allows for an automatic, fast, and repetitive weighing and dosing process, reducing manual intervention. It can be integrated with: Elevators and feeding systems Product conveyors Vertical packaging machines Pouch packaging machines Tray and container filling machines Dosing systems Weight controllers Metal detectors Iodpfjzw D Htox Ahyjbc Packaging and end-of-line equipment APPLICATIONS Especially suitable for food industries, frozen food manufacturers, snack producers, vegetable processors, prepared food companies, and packaging companies that require automatic weight-based dosing. Depending on its configuration, it can be used for a wide variety of solid, granular, diced, or portionable products. The combination of BILWINCO technology and 14 weighing heads provides a particularly interesting solution for automatic lines that require precision and continuity in dosing. Machine available for inspection. Additional technical information, dimensions, additional photographs, or videos can be provided upon request.
