In the production of pharmaceutical APIs, fine chemicals and powder intermediates, metering accuracy, dust‑tight sealing and process continuity of material packaging directly affect finished‑product quality and workshop production efficiency. As an essential part of powder production lines, API mixing packaging machines and vacuum raw‑material packaging machines are capable of quantitative sealing for powder and granular materials. Guangzhou Marchi Packaging Equipment Co., Ltd., with 27 years of practical experience in packaging equipment, provides MC‑DLLB‑100L series API mixing vacuum packaging‑related equipment and complete‑line supporting services. It supports manufacturing enterprises in model selection, equipment configuration and production‑line process construction.
Core Equipment Configuration and Key Parameters
The MC‑DLLB‑100L API mixing packaging machine adopts a bottom‑filling operation mode. Materials are filled from the bottom of packaging bags with a low falling distance to reduce dust generation. It is suitable for powder and small‑granule materials with high packaging‑precision requirements, uneven density, good or poor flowability.
The whole machine features an all‑stainless‑steel structure equipped with combined and open transparent hoppers. Operators can complete disassembly and cleaning without tools, facilitating cleaning for material change‑over in workshops and lowering the risk of cross‑contamination between different materials. The pneumatic bag‑clamping device and bracket are mounted on load cells. The equipment performs segmented fast‑and‑slow filling according to preset weight parameters. Equipped with a high‑response weighing system, it helps achieve stable packaging accuracy. Controlled by PLC with a touch‑screen human‑machine interface, the machine features simple operation logic. The system can store 10 sets of product adjustment parameter recipes. Stored recipes can be directly called when switching to different‑material production to reduce on‑site commissioning time.
This model features a packaging weight range of 5‑25 kg, packaging accuracy of ±0.1～0.5 %, and a packaging speed of 1‑4 bags per minute. Power supply specification: 3P AC 208‑415V 50/60Hz; total power: 2.87 kW; net weight: 450 kg. During model selection, enterprises may communicate with the manufacturer about configuration adjustments according to their own material characteristics, target packaging weight and workshop capacity planning to match actual production conditions.
Equipment Application Scenarios and Processable Materials
Application scenarios for API mixing packaging machines and vacuum raw‑material packaging machines cover pharmaceutical API production, pharmaceutical intermediate processing, fine chemicals, certain food additives, mineral powders, dyes and pigments, feed additives and other processing fields. Processable materials include API powders, pharmaceutical‑powder intermediates, various fine powders, agglomerated powders, light‑weight powders, heavy‑weight powders, crystalline granules and fine granular materials.
For production conditions requiring workshop dust control and metering stability, the equipment can be integrated into the whole production line and connected with upstream and downstream mixing, conveying and testing equipment to realize continuous production.
Complete Packaging Workflow
The whole workflow starts with upstream material conveying. Materials are delivered into the equipment hopper. Operators finish bag loading, and packaging bags are firmly fixed by the pneumatic bag‑clamping mechanism. Bottom‑filling is then started. The filling nozzle extends to the bag bottom to perform graded fast‑and‑slow feeding. The weighing system collects weight data in real‑time and stops feeding once the preset weight is reached.
Upon completion of filling, bag‑mouth sealing is carried out. Sealed finished bags are conveyed outward by the conveying mechanism and can be connected to check‑weighing and foreign‑matter detection processes. Qualified packaging bags after inspection keep moving along the conveying line to the palletizing station, where supporting palletizing equipment neatly stacks finished bags. Continuous operations from material filling, sealing and inspection to palletizing are realized, reducing intermediate manual handling.
Common Industry Pain Points and Corresponding Solutions
Many powder‑producing enterprises encounter various practical problems in the packaging phase. Corresponding solutions are sorted out combined with equipment characteristics:
Heavy dust during material packaging and cumbersome cleaning for material change‑overPain Point: Dust is easily generated during powder filling, impairing the workshop environment; equipment disassembly and cleaning are troublesome, and cross‑contamination may occur when switching between different materials.Solution: Adopt the bottom‑filling structure to reduce dust. The transparent hopper allows tool‑free disassembly for quick washing after production, meeting cleaning requirements for multi‑variety rotating production.
Fluctuating material density and unstable packaging metering valuesPain Point: Some powder materials feature uneven density and variable flowability, resulting in packaging‑weight deviation fluctuations and material loss.Solution: Rely on high‑response weighing sensor components, fast‑and‑slow segmented filling mode together with the recipe‑storage function. Store adapted parameters for different materials to mitigate metering fluctuations caused by density variations.
Long commissioning time for production change‑over and high operator skill requirementsPain Point: Repeated parameter commissioning is required when switching product specifications, placing high demands on operator experience.Solution: The equipment is equipped with a touch‑screen human‑machine interface. Multiple sets of production recipes are pre‑saved. Existing recipes can be directly recalled for material‑specification replacement to shorten commissioning time and lower operation barriers.
High manual input for handling and stacking after packagingPain Point: Transfer and stacking of finished bags after packaging rely on manual labour with high labour intensity and insufficient overall production‑line continuity.Solution: The equipment can connect to conveying lines and downstream palletizing units, extending packaging procedures to automatic palletizing, streamlining the whole production line and reducing manual intervention.
As an original manufacturer of packaging equipment, Guangzhou Marchi Packaging Equipment Co., Ltd. leverages years of practical project experience to carry out model‑selection evaluation combined with customer material samples, workshop conditions and capacity plans, and provide equipment configuration suggestions. It helps enterprises obtain suitable solutions for API mixing packaging machines and vacuum raw‑material packaging machines matching their actual working conditions.
