Adjustable Automatic Master Potato Baler


The JMC Adjustable Automatic Master Potato Baler is an automated bagging system which gently counts, accumulates and packs pre-packaged bags into Master poly and paper bale bags. Also, aptionally into Mesh masters. Once filled the Master Bags are automatically moved via a conveyor in an upright position to be closed/sealed.

The system can be interfaced with the optional JMC FuseAire4 hot air sealer to close poly masters or with the optional integrated sewing head option for paper masters. It can also be integrated with most automatic closing devices and is compatible with all product bag types over from poly to paper Master Bags in minutes. The JMC “Space Saver” Incline Conveyor provides a compact footprint and the optional “Automatic Bypass” makes it ideal for loose stacking into bin boxes, RPC’s or re-routing product to an alternate process without the need to move or re-configure equipment.

The system handles potato bags ranging in size from 3 lbs to 20 lbs.



POWER: 230 volt 3 PH. 60 Hz
