Preformed Bag Weighing and Packaging Machine — Fresh Corn Seeds
2026-07-13
The MG-150SW is a pre‑formed bag weighing and packaging machine designed for portioning seeds of cruciferous crops, leafy vegetables, and sweet corn. Leveraging a proven weighing‑and‑metering architecture and a dedicated opening‑and‑closing mechanism for pre‑formed bags, it addresses industry‑specific challenges such as the relatively large particle size of corn seeds, stringent single‑bag weight‑control requirements, and low efficiency in manual sealing of pre‑formed bags. It is the flagship model for seed companies engaged in retail small‑packaging and channel‑wide bulk‑packaging of sweet corn seeds.
The equipment is equipped with a pre‑formed bag‑opening mechanism that eliminates the need for manual bag‑mouth spreading. Paired with a high‑precision weighing and metering system, the entire process—from bag loading and mouth opening to precise dosing and filling, bag sealing, and finished‑product discharge—can be fully automated. The machine’s operating logic is straightforward and easy to understand; after minimal training, operators can independently manage equipment operation and parameter adjustments, reducing repetitive manual tasks and significantly boosting the overall packaging efficiency of fresh‑corn seeds.
The equipment offers flexible compatibility with a wide range of bag sizes, accommodating small pouches as tiny as 100×120 mm and large pre‑formed bags up to 240×300 mm. It seamlessly handles everything from small, color‑printed trial‑size bags for farmers to high‑volume, standard‑size packaging for corn seed distribution. With a maximum packaging capacity of 2,000 ml, it meets the diverse portioning needs of fresh‑corn seed varieties across different weight specifications. Packaging speeds remain steady at 8 to 15 bags per minute, ensuring smooth production of routine daily orders while effortlessly managing urgent, peak‑season rush‑packing tasks.
The entire machine operates on a standard 220V power supply and is equipped with a stable pneumatic system, consuming 200 NL of air per minute—conditions readily available in most typical workshop environments. Its external dimensions are 1,700 mm long, 600 mm wide, and 1,100 mm high, with an overall weight of approximately 380 kg. The robust, heavy‑duty frame ensures minimal operational vibration, maintaining consistently stable weighing results that are largely unaffected by workshop dust or variations in the feeding rhythm. This guarantees that the net content of each bag of fresh‑corn seed meets the labeled specifications, thereby minimizing post‑sale issues caused by weight deviations. The main body is constructed from stainless steel, offering excellent resistance to dust and easy daily cleaning and maintenance, fully complying with the clean‑production standards of seed‑processing facilities. It prevents contaminant ingress, better safeguarding both the storage quality of the seeds and their subsequent germination performance.
