In the packaging process of powder materials such as milk powder, soybean milk powder, milk powder and protein powder, metering accuracy, dust control and packaging efficiency have always been the core indicators concerned by manufacturers. As a powerful original manufacturer with 27 years of experience in automated packaging, Guangzhou Marchi Packaging Equipment Co., Ltd. and Hefei Marchi Packaging Equipment Co., Ltd., relying on solid R&D and manufacturing capabilities as well as rich experience in whole-line projects, have launched the MC-DLLB-100L semi-automatic large-bag milk powder packaging machine (medical-grade milk powder packaging machine / M-type milk bag packaging machine), delivering high-precision and low-dust powder packaging solutions for food, pharmaceutical, chemical and other industries.
I. Equipment Advantages: Bottom-Filling Technology Resolves Two Core Difficulties in Powder Packaging
The MC-DLLB-100L semi-automatic large-bag milk powder packaging machine adopts bottom-filling technology. Materials are fed from the bottom of packaging bags during filling with a small material drop height to effectively control dust generation. This design is especially suitable for powdery and small granular materials that require high packaging precision, feature uneven density, or have good or poor flowability.
The core advantages of the equipment are shown as follows:All-stainless steel structure for easy cleaningConstructed entirely of stainless steel, the machine is equipped with combined or open transparent material hoppers that can be quickly disassembled and cleaned without special tools, complying with strict hygiene standards of the food and pharmaceutical industries.
High-precision weighing system to guarantee full net content for each bagThe pneumatic bag clamping device and support bracket are mounted on weighing sensors, which perform fast and slow feeding according to preset weights. The high-response weighing system ensures outstanding metering precision.
Intelligent control for easy operationIt adopts PLC control with a touch screen human-machine interface for straightforward operation. Parameter formulas for various products can be stored for subsequent use, supporting storage of up to 10 sets of formulas.
Compatibility with multiple bag types and materialsThe machine handles large-bag products with specifications ranging from 5 kg to 25 kg, applicable to various powders including milk powder, soybean milk powder, dairy powder, protein powder, whey powder, almond powder, coconut powder, grain powder, oat powder, rice flour, peanut powder, red date powder, corn powder, soybean powder, coconut milk powder, peanut milk powder, brown rice flour, lotus root starch, Chinese yam powder and more.
II. Application Scenarios Covering Three Major Sectors: Food, Pharmaceuticals and Chemicals
This equipment is widely deployed in diverse industrial scenarios:Food Industry: Quantitative packaging of edible powders such as milk powder, soybean milk powder, dairy powder, protein powder, coffee powder, starch, wheat flour, glutinous rice flour, corn flour, powdered sugar and seasoning powder.Pharmaceutical Industry: Packaging of materials with stringent hygiene and metering requirements, including pharmaceutical raw material powders, traditional Chinese medicine powders, health supplement powders and medical-grade milk powder.Chemical, Agriculture and Animal Husbandry Industry: Weighing and packaging of powders such as calcium powder, graphite powder, additives, premixes and feed powder.
III. Full Packaging Workflow: Manual Bag Sleeving to Automatic Palletizing
Though classified as a semi-automatic model, the MC-DLLB-100L realizes automatic operation in the core filling stage; only manual bag sleeving is required, while all subsequent procedures are completed automatically by the machine. The complete packaging process is as follows:
Manual bag sleeving: Operators fit empty packaging bags onto the pneumatic bag clamping device, which automatically clamps and secures the bags.
Automatic metering and filling: Based on preset weight parameters, the bottom-filling system carries out two-stage fast and slow feeding from the bag bottom. The high-precision weighing system monitors weight in real time, controlling the net content error of each bag within ±0.1%～0.5%.
Automatic sealing: Upon completion of filling, the machine automatically performs heat sealing or bag stitching of the bag mouth.
Conveying and inspection: Sealed finished bags are transported via conveyor belts, which can be matched with checkweighers for secondary inspection to ensure qualified weight of all products.
Automatic palletizing: Qualified bags are conveyed to the palletizing station, where palletizing robots or automatic palletizers stack the bags neatly. Marchi’s automated palletizing packaging production line can integrate case erectors, case sealers, palletizers and other equipment to achieve full automatic processing from packaging to palletizing, effectively boosting production efficiency and packaging quality. Only one operator is needed for bag sleeving on the entire production line; paired with automatic sealing and palletizing, each line can reduce the workforce by 3 to 4 packers.
IV. Solutions to Customer Pain Points
Marchi provides systematic solutions targeting common pain points prevailing in the powder packaging industry:Pain Point 1: Severe dust pollutionUltra-fine powders such as milk powder tend to generate massive dust during filling, deteriorating the workshop environment and endangering operators’ health. Equipped with bottom-filling technology featuring minimal drop height and a dust removal interface, the MC-DLLB-100L produces barely visible dust on site.
Pain Point 2: Unstable metering accuracyConventional equipment suffers large measurement errors when filling ultra-fine powders, easily triggering measurement disputes and material waste. Supported by a high-response weighing system and automatic re-inspection & rejection function, this machine limits the net content error within ±0.5%.
Pain Point 3: High labor costs and low efficiencyTraditional large-bag packaging requires coordinated work of multiple workers. Marchi’s semi-automatic solution only needs one worker for bag sleeving, with fully automatic follow-up procedures. Combined with an automatic palletizing system, labor intensity and labor costs are greatly cut down.
Pain Point 4: Difficult equipment cleaning and maintenanceThe food and pharmaceutical industries impose strict hygiene requirements on equipment. The all-stainless steel structure paired with tool-free disassembly and cleaning design drastically shortens cleaning time and improves equipment turnover efficiency.
