In the field of granular material packaging, fully automatic 25kg packaging machines have become vital equipment for enterprises to boost production efficiency and cut labor costs. Designed for medium-specification bulk bag packaging requirements, the 25kg large-bag packaging machine is widely applied in food, chemical, feed and other industries. Featuring stable weighing precision and automatic running performance, the 25kg granular packaging machine is gradually replacing conventional manual or semi-automatic packaging modes. As an original reputable packaging equipment manufacturer with 27 years of technical accumulation, Guangzhou Marchi Packaging Equipment Co., Ltd. launches MCZD-25K fully automatic 25kg granular packaging machine to deliver integrated packaging solutions covering raw material feeding through finished product palletizing.

I. Core Equipment Advantages
Marchi MCZD-25K adopts precise and reliable mechanical operation to replace manual weighing, bag fitting and conveying procedures. It integrates automatic weighing, automatic bag loading, automatic filling, automatic bag delivery and automatic sealing to realize continuous automatic operation. Designed with fully enclosed structure and safety interlock devices such as door opening detection, all execution units are equipped with control and safety parts to guarantee safe and convenient operation. Developed targeting the features of granular materials, the machine can steadily process rice, corn, wheat, soybean, peanut, mixed grains, feed pellets, plastic pellets, fertilizer granules, resin pellets, salt, white granulated sugar, monosodium glutamate, tea, soybean meal, frozen vegetables, frozen fruits and various other granular products.
Key Parameters: Max. packaging capacity 4～6 bags per minute, filling weight 10～25 kilograms per bag, applicable bag materials including paper bag, plastic bag and woven bag, bag dimension length 600～1100mm × width 300～600mm, air consumption 750 standard liters per minute, total installed power 3kW.
II. Core Configuration and Model Selection
The machine is fitted with high-precision weighing system and three-stage fast-medium-slow filling control technology to limit weighing deviation within ±0.2%. Equipped with PLC plus touch screen HMI, operators can set parameters and monitor running status intuitively. The equipment is embedded with intelligent protection logics: no feeding without bags, no feeding for incompletely opened bags and no sealing without materials. Optional functions include door opening detection and low air pressure alarm to further improve safety and operational stability.
III. Complete Packaging Process
The full workflow from raw material feeding to finished pallet stacking is listed below:
- Automatic Feeding: Bin sensors monitor material level to avoid material shortage or overstocking.
- Automatic Weighing: High-precision load cells work with three-stage high-medium-low speed feeding; feeding stops automatically once reaching preset target weight.
- Automatic Bag Loading: Bag loading manipulator picks bags from bag storage bin and accurately positions them at filling station to replace manual bag sleeving.
- Automatic Filling: Materials drop into bags via dust-proof feeding hopper to minimize dust emission.
- Automatic Bag Conveying: Filled bags are transferred to sealing station by conveyor belts.
- Automatic Sealing: Stitch sealing or heat sealing is adopted according to woven bag, plastic bag or paper bag material to achieve tight leak-proof closure.
- Automatic Transport: Sealed bags pass through checkweigher conveyor for subsequent sorting.
- Palletizing: Finished 25kg bags are delivered to palletizing system, where palletizing manipulator automatically grabs, arranges and stacks bags into neat pallets, completing full automatic packaging from bulk raw materials to palletized finished goods.
IV. Application Scenarios
This equipment is applicable to food processing (rice, corn, soybean, wheat, peanut, mixed grain, tea, monosodium glutamate, white granulated sugar, edible salt), feed production (all types of pellet feed), fertilizer manufacturing (urea, compound fertilizer, potash fertilizer, phosphate fertilizer), chemical raw materials (plastic pellets, resin pellets, rubber pellets), building materials (quartz sand, stone aggregate, barite) and frozen food industries (frozen vegetables, frozen fruits).
V. Common Industry Pain Points and Corresponding Solutions
Pain Point 1: High labor cost and difficulty in worker recruitmentTraditional packaging lines require multiple staff for bag fitting, weighing, sealing and handling.Solution: Fully automatic 25kg packaging machine replaces several manual posts to drastically cut labor expenditure and labor intensity.
Pain Point 2: Large weighing error and excessive material lossUnstable performance of manual or semi-automatic equipment causes obvious weight fluctuation.Solution: High-precision weighing system plus intelligent three-stage feeding ensures accurate single-bag weight and reduces raw material wastage.
Pain Point 3: Low production efficiency failing to fulfill bulk ordersLow running speed and poor station coordination of conventional equipment restrict output.Solution: Stable production capacity of 4～6 bags per minute plus full-process automation from feeding to palletizing greatly improves overall throughput.
Pain Point 4: Inconsistent packaging appearance damaging brand imageManual operation easily leads to loose sealing and irregular finished package shape.Solution: Automatic sealing and standardized robotic palletizing guarantee uniform appearance and reliable sealing of all finished bags.
