Equipment Model Selection and Core Configuration
To satisfy automatic quantitative filling demands of well-flowing granular materials, Marchi launches MCGZ-JZ full-automatic granular filling machine. The equipment is compatible with various cans including PE cans, aluminum cans, paper cans and tin cans, and customized moulds are available upon customer requirements with strong container adaptability. Featuring high automation degree and coordinated full-line operation, it complies with GMP standards.
In terms of core configuration, the machine consists of bottle unscrambling system, metering & filling system, capping system and rear conveying & palletizing system. Operators place empty bottles on the unscrambler, which automatically arranges and orients bottles and feeds them orderly to filling stations. Optional auxiliary devices such as weight sorter, automatic desiccant pouch inserting machine, bottle surface dedusting device, manual operation station, inkjet printer and automatic soft cap sealing unit can be equipped to build a complete granular filling production line according to actual production needs.

Full Packaging Process Analysis: From Bottle Unscrambling to Palletizing
The full workflow of MCGZ-JZ full-automatic granular filling machine covers bottle unscrambling, metered filling, capping, conveying and palletizing to form an integrated automatic packaging line.
Bottle Unscrambling Stage: Operators feed empty bottles into the hopper of the unscrambler. Equipped with rotating disc and guiding mechanism, the unscrambler sorts and aligns bottles automatically and conveys them towards filling stations in uniform direction. Adjustable structure fits containers of different specifications.
Metered Filling Stage: Upon arriving at filling station, bottles are positioned and clamped automatically. The metering system performs quantitative weighing based on preset weight, and granular materials are accurately filled into bottles via blanking structure. Adopting high-precision load cells and dynamic compensation algorithm, the equipment maintains stable filling accuracy even under high-speed operation.
Capping Stage: After filling, bottles are transported to capping station automatically. Optional automatic cap sorter arranges caps and delivers them to capping heads for automatic screwing or pressing. An extra soft cap sealing unit is available for products requiring soft closure.
Conveying and Palletizing Stage: Capped finished bottles are sent to subsequent procedures by conveyor belts. Optional supporting equipment includes weight sorter to reject off-spec products, inkjet printer for production date and batch coding, and automatic desiccant feeder to insert desiccant before capping. Final finished bottles are collected on workbench and stacked manually or by automatic palletizer into palletized units for convenient storage and delivery.
Common Industry Pain Points and Marchi Solutions
Pain Point 1: Unstable packaging accuracy
Many manufacturers suffer big metering deviation and obvious precision fluctuation, resulting in raw material waste and defective finished goods.
Solution: Marchi MCGZ-JZ is equipped with high-precision weighing sensors and dynamic compensation algorithm to control filling accuracy within ±0.3～1.5% and effectively cut material loss.
Pain Point 2: Long commissioning time for product switching
Frequent change of container types and materials under multi-variety small-batch production leads to lengthy debugging and production halt.
Solution: The machine allows flexible adjustment within bottle diameter 35～100mm and bottle height 40～200mm for easy specification conversion and shortened changeover duration.
Pain Point 3: Poor coordination among full production line
Mismatched conveying speed and poor connection between working stations lower overall production efficiency.
Solution: Marchi provides integrated full-line solutions covering unscrambling, filling, capping, conveying and palletizing. All stations run in linkage with automatically matched conveying and filling speed to realize efficient line coordination.
Pain Point 4: Unstable sealing performance
Loose caps cause air leakage and material spillage and shorten product shelf life.
Solution: Built-in automatic cap sorting and sealing system enables precise adjustment of sealing pressure and torque to meet closure requirements of various caps.
Pain Point 5: Slow after-sales service response
Delayed equipment maintenance causes long-time production shutdown upon breakdown.
Solution: Marchi sets up complete after-sales service system with professional technicians for timely on-site support. Electronic and physical backups of equipment drawings, spare parts list, programs and operation manuals are well preserved for fast troubleshooting.
With stable metering precision, flexible container compatibility and integrated full-line solution, Marchi MCGZ-JZ full-automatic granular filling machine delivers reliable automatic packaging solutions for granular material manufacturers.
