As the dairy and nutritional powder industries accelerate upgrading toward automation, cleanliness and extended shelf life, dedicated packaging lines featuring stable operation, precise filling and vacuum fresh-keeping capacity have become core equipment for numerous manufacturers to build quality competitiveness. Relying on 27 years of continuous innovation and manufacturing accumulation in automated packaging, Guangzhou Marchi Packaging Equipment Co., Ltd. and Hefei Marchi Packaging Equipment Co., Ltd., its two major production bases, launch factory-specific turnkey production line solutions centered on milk powder vacuum packaging machines for milk powder, protein powder and various high-value powders, helping customers build continuous packaging workflows from filling to palletizing.
Dual Production Bases In-house: Focused on Automated Powder Packaging
As an original packaging machinery manufacturer, Guangzhou Marchi and Hefei Marchi have developed mature technical systems covering powder metering & filling, vacuum sealing and post-process automatic palletizing. The company’s engineering team can tailor production lines according to the characteristics of materials including milk powder, soymilk powder, nutritional rice flour, meal replacement powder, coffee powder, solid beverage powder, enzyme powder, seasoning powder, as well as certain veterinary medicinal powders and fine chemical powders. The newly promoted milk powder packaging production line adopts a modular structure centered on bottom-up filling technology, sequentially connected with vacuum sealing, weight inspection, metal detection, case erection, case packing and robotic palletizing stations, delivering full-process equipment solutions from raw material receiving to finished product warehousing for factory-specific milk powder packaging scenarios.
Core Model and Configuration: MC-DLLB-100L Bottom-Up Filling Machine
The core filling unit of this production line is the MC-DLLB-100L bottom-up filling system. Materials are filled from the bottom of packaging bags with low material drop height and nearly zero dust emission, making it particularly suitable for powders such as milk powder with moderate flowability, high dust generation tendency and stringent hygiene requirements. Its all-stainless steel structure and combined/open transparent hoppers can be quickly disassembled and cleaned without special tools, complying with clean production standards for food and health products. The pneumatic bag clamping device and support bracket are directly mounted on weighing sensors; equipped with a high-response weighing system, the machine automatically performs fast and slow feeding according to preset weights to ensure excellent metering consistency. The control system adopts PLC together with a touch screen human-machine interface, capable of storing parameter formulas for 10 different products for one-click recall, drastically shortening product changeover time.
Core Parameters:
Packing weight range: 5～25 kg Packing accuracy: stably maintained at ±0.1%～0.5% Packing speed: 1～4 bags per minute Total machine power: 2.87 kW Universal three-phase power supply: AC 208～415V 50/60Hz Net machine weight: approximately 450 kg Low requirement for factory floor bearing capacity with flexible installation.
Full Production Line Packaging Workflow: From Filling to Palletizing
On-site operation workflow: Materials are delivered into the machine hopper through sealed pipelines. Operators fit bags onto the pneumatic bag clamping ports and start the system; the machine automatically clamps bags and initiates filling, with weighing sensors feeding back data in real time. Filling stops once the preset weight is reached, the bag clamp releases, and the bag pushing mechanism smoothly transfers filled bags out. Bags are then conveyed to a double-chamber vacuum sealing machine, which evacuates air to meet process standards before heat sealing, effectively lowering residual oxygen inside bags and inhibiting milk powder oxidation, caking and microbial proliferation. Sealed bags pass through a checkweigher and metal detector sequentially, with non-conforming products automatically rejected to guarantee outgoing product quality. In the subsequent procedure, an automatic case erector opens empty cartons; parallel robots or spider robots pick qualified packaged bags and load them into cartons, followed by carton sealing via a case sealer. Finally, palletizing robots stack finished cartons onto pallets in preset layouts for subsequent forklift transportation and warehousing. The whole workflow features seamless connection with minimal manual intervention; the overall production capacity and cleanliness meet the stable and efficient operational requirements of factory-dedicated milk powder packaging lines.
Multi-Material Compatibility to Improve Factory Production Flexibility
Apart from infant formula milk powder, adult milk powder, middle-aged and elderly milk powder and modified milk powder, the same milk powder packaging production line can handle soybean protein powder, pea protein powder, whey protein powder, nutritional meal replacement powder, mixed grain powder, turmeric powder, ganoderma lucidum powder, tea powder, coffee powder, non-dairy creamer, food premixes, veterinary medicinal powders and fine chemical powders by replacing a small number of customized components or adjusting parameters. Bottom-up filling delivers outstanding performance for powders and small granules with poor flowability or uneven density, enabling factories to rapidly switch between diversified orders and reduce equipment idle time.
Targeted Pain Point Resolution: Marchi Customized Production Line Solutions
Dairy powder and high-value powder packaging has long been plagued by multiple challenges: dust pollution endangering workshop environment and operator health, weighing inaccuracies damaging consumer trust, insufficient vacuum degree accelerating fat oxidation and caking deterioration, as well as heavy workload and high error rates in manual post-process palletizing and handling. Targeting these practical customer pain points, Marchi equips the milk powder packaging line with bottom-up drop height control technology to minimize dust emission; the high-precision weighing and feedback system restricts metering error within ±0.5%, paired with weight data traceability to avoid insufficient net content; double-chamber vacuum sealing ensures far lower residual oxygen than conventional heat sealing and greatly extends shelf life; robotic palletizing systems replace manual handling with stable cycle rates, neat stacking shapes and reduced product breakage rates. Meanwhile, the 10-set formula storage function, tool-free detachable hopper structure and compatibility with various bag specifications maintain high line efficiency during frequent product changeovers. As an original manufacturer, Guangzhou Marchi Packaging Equipment Co., Ltd. and Hefei Marchi Packaging Equipment Co., Ltd. provide continuous support covering equipment selection, process commissioning and after-sales service, together with remote operation & maintenance modules to help customers swiftly respond to market changes.
Against the industry trend of food safety assurance, stable quality and intelligent manufacturing in dairy products, protein products and various fine powder sectors, dedicated production lines optimized for cleanliness, precision, fresh-keeping and automated connection have become standard configuration for high-end manufacturing plants. Drawing on solid manufacturing experience and mature milk powder packaging line solutions, Marchi’s dual production bases continue to deliver flexible and reliable equipment support for dairy processing, health food and fine chemical enterprises. Leveraging integrated line strengths of "dust-free filling + vacuum fresh-keeping + intelligent palletizing", Marchi helps customers gain market recognition for superior product quality.
