I. Equipment Advantages
Marchi fully automatic nut packaging machine features intelligent control and high-precision operation. Driven by three-servo system and equipped with internationally renowned control components, the equipment runs stably and is easy to operate. The multi-head combination weigher conducts dynamic weighing via multiple independent hoppers to realize high-precision metering for nuts and effectively reduce raw material waste. Adopting man-machine interface combined with PLC control system, the machine allows convenient parameter adjustment and rapid specification switching.
II. Packaging Process: From Nut Bag Loading to Finished Product Palletizing
Taking Marchi packaging production line as an example, the fully automatic nut packaging machine covers the complete process leading to post-stage palletizing:
Bag Loading → Coding → Zipper Opening → Bag Opening → Metering and Discharging → Cleaning → Heat Sealing → Shaping → Palletizing
Detailed description: The automatic bag picking mechanism grabs empty bags and sends them to the bag clamping station. Thermal transfer or laser coder prints production date and batch number. For stand-up zipper bags, the zipper opening device unzips bags automatically, and vacuum suckers prop bag mouths open. The multi-head combination weigher finishes weighing and feeds materials through the discharging hopper with metering accuracy of ±0.2%～0.5%. The bag mouth cleaning device removes residual debris. The intelligent temperature control system automatically adjusts sealing temperature according to bag material. The shaping device regularizes package appearance. Finished bags are delivered to the rear section via conveyor belts. Cooperated with case erector, case packer, case sealer and automatic palletizing system, the whole line completes automatic case unpacking, packing, sealing, strapping and palletizing, realizing full-line unmanned operation.
III. Application Scenarios and Equipment Parameters
Marchi fully automatic nut packaging machine is applicable to various materials: pistachios, almonds, walnut kernels, cashews, pine nuts, pecans, melon seeds, peanuts, macadamia nuts, apricot kernels, hazelnuts, walnuts, mixed nuts, roasted nuts, nut crisp, daily nuts, nut gift boxes and so on. Applicable bag types include stand-up bag, zipper bag, spout stand-up bag and flat bag.
Key Equipment Parameters (Model: MCGD8-200)
- Packaging Size (Length × Width): 100～300mm × 100～200mm
- Packaging Speed: 25～90 bags per minute
- Applicable Materials: PE composite film, aluminum foil film, aluminized film and other composite films
- Bag Width Adjustment: Automatic adjustment (motor-controlled synchronous one-key adjustment for all grippers)
Core Configuration: Multi-head combination weighing system, three-servo film pulling system, intelligent temperature control sealing system, PLC man-machine interface, automatic bag width adjusting mechanism, color mark photoelectric detection system, no-bag or incomplete bag opening detection device. Parts in contact with materials are made of 304/316 stainless steel or food-grade plastic, complying with hygiene standards. The equipment is equipped with multiple safety detections: No feeding without bags or incomplete bag opening; No discharging if bags fail to open; No sealing without bags or materials. Optional alarm and shutdown functions are available for door opening, missing color band, insufficient air pressure and abnormal sealing temperature.
IV. Customer Pain Points and Solutions
Pain Point 1: Insufficient packaging accuracy causing severe raw material waste
Manual weighing has an error up to ±5 grams per bag, and the loss rate of high-value nuts exceeds 15%.
Marchi Solution: The multi-head combination weigher controls metering accuracy within ±0.2%～0.5%, greatly cutting down raw material loss.
Pain Point 2: Poor sealing performance leading to nut oxidation and shortened shelf life
Nuts are rich in grease. Invasion of oxygen will cause rancidity and deteriorated taste.
Marchi Solution: Optional nitrogen flushing or vacuum packaging combined with high-precision heat sealing system effectively reduces residual oxygen inside bags and extends shelf life.
Pain Point 3: Low production efficiency failing to meet peak season orders
The daily output of manual packaging is limited, resulting in order backlog and delayed delivery.
Marchi Solution: The packaging speed reaches 90 bags per minute. Cooperated with post-stage automatic palletizing system for full-line unmanned operation, the daily output of a single line is several times higher than manual packaging.
Pain Point 4: High equipment failure rate and slow after-sales response
Some equipment frequently breaks down under continuous high-intensity operation with delayed maintenance, leading to production interruption.
Marchi Solution: Adopting internationally famous control components for stable operation. The manufacturer provides one-year warranty and lifelong maintenance service, as well as whole factory scheme design and technical support.
V. Conclusion
From single packaging machine to complete production line, from nut bag loading to finished product palletizing, Marchi Packaging Equipment provides full-process automated solutions. As a packaging machinery manufacturer with 27 years of industrial experience, Marchi will continue to help nut processing enterprises realize intelligent upgrading and efficiency improvement in packaging links with high-quality equipment and professional technical services.
