{"product_id":"powder-weighing-large-bag-line","title":"Fully Automatic Powder Weighing Production Line For Large Bag","description":"\u003cp\u003eKeypack Intelligent Fully Automatic Powder Weighing Production Line For Large Bag is a high-precision automatic weighing and pre-made bag filling system engineered for continuous, dust-free packaging of powdered materials in food, pharmaceutical, and chemical industries. It delivers up to 200 bags per hour with a bag clamp capacity of 25 kg, driven by a new-generation PLC control system and built with SUS304 stainless steel on all product-contact surfaces with polished finish. Ideal for milk powder, health-care powder, solid beverages, food additives, and solid pharmaceutical powder requiring reliable big-bag automatic weighing line solutions.\u003c\/p\u003e\n\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\u003cp\u003eThe Fully Automatic Powder Weighing Production Line For Large Bag is a purpose-built automatic weighing line designed for high-volume, pre-made open-mouth bag filling of fine powder materials. Unlike small-sachet VFFS machines, this system is engineered specifically for large-format open bags — handling bag sizes from 750–950 mm (L) × 400–550 mm (W) with a bag clamp load capacity of 25 kg — making it the ideal solution for producers requiring big-bag powder packaging with consistent fill accuracy and dust-free operation.\u003c\/p\u003e\n\u003cp\u003eThe production line integrates automatic bag feeding, gripping, opening, powder filling, air exhaust, and sealing into a single continuous automated process. Adopting a new-generation production control system paired with a high-precision, high-speed dedicated metering controller, the line delivers strong functionality, high reliability, and excellent scalability — fully adapting to the demands of continuous production in food-grade, pharmaceutical-grade, and industrial powder packaging environments.\u003c\/p\u003e\n\u003cp\u003eEquipped with Keypack Intelligent (Kunbupack) automatic weighing line control architecture, the system supports both automatic and manual operation modes with self-locking logic, real-time operation monitoring, PLC I\/O point comparison, and PLC backup point replacement — ensuring maximum uptime and production continuity for multi-shift powder packaging operations. All product-contact parts are manufactured from SUS304 stainless steel with surface polishing treatment, meeting GMP standard requirements for dust-free powder handling.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBag Clamp Load Capacity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e25 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBag Size Range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e750–950 mm (L) × 400–550 mm (W) × 0–100 mm (gusset)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBag Style\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eOpen-mouth bag (pre-made)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBag Feeding Speed\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eUp to 200 bags\/hour (actual speed subject to customer's auger discharge rate)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProduct-Contact Material\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSUS304 stainless steel, surface polished\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFrame Material\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHigh-quality carbon steel with powder coating\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePower Consumption\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3.5 kW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMachine Weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eApprox. 3,000 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eControl System\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePLC system with touchscreen interface\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMinimum Air Pressure\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.40 MPa (auto-stop below this threshold)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eKey Features and Machine Characteristics\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic \/ Manual Mode with Self-Locking:\u003c\/strong\u003e Supports seamless switching between automatic and manual operation modes.
