Erie Technical Systems UltiMAX™ Bulk Bag Unloaders are designed to manually or automatically unload bulk bags. Our Bulk Bag Unloaders, also known as Bulk Bag Dischargers safely support bulk bags with a lifting frame. The frame can be used with a forklift or an optional hoist and trolley system. Once the bulk bag is in place, the operator can untie the bottom bag spout in a dust-tight environment. Flow out of the bag can then be controlled either manually or automatically. The UltiMAX™ bulk bag unloader can be paired with Erie Technical Systems FlexMAX® flexible screw conveyor, ValuMAX®, or a vibratory feeder to create a system to meet the specifications of each application.

Flexible Auger Screw Conveyor option, for our Manual and Automatic Bulk Bag Unloading Equipment, will be used to transport the product from the bulk bag unloader to your process.
The Bag Spout Pinch Ring option, for our Manual and Automatic Bulk Bag Unloading Equipment, incorporates a pinch ring assembly which is pneumatically operated. Once the operator has placed the bag into position the bulk bag outlet spout is stretched over the product flow tube and they can actuate the pinch ring. The ring is driven down and pinches the bag spout between the ring and the top of the product flow tube.
The V-form valve option on the UltiMAX bulk bag unloaders provides a means to seal the bag off and re-tie or to simply stop the flow of material to the process. The valve is actuated with two pneumatic cylinders that move the v-shaped rounded bars toward each other. This pinches bag outlet spout tightly and stops flow out of the bulk bag. The v-shaped bars are made from solid stainless steel. The standard valve is operated by a manual 3-position pneumatic toggle lever valve. The valve is also available in an electrically controlled version for use in automated systems.
Paddle flexors are a useful option for our Manual and Automatic Bulk Bag Unloading Equipment if the bulk material being unloaded tends to set up during shipment. This option provides a means to condition the bag to enhance the flow out of the bag into the process. The two ribbed flexing paddles can move from a flat position to a combined angle of 85 degrees (nearly vertical). It is designed with bag conditioning ribs which engage the bag and breaks up lumps or agglomerations of material in the bulk bag.
The Bag Untie Box when added, allows for the operator to handle the bag spout in an enclosed area to reduce dust generation when preparing the bulk bag for the unloading process. The Untie box includes a hinged, sealed door that is closed during discharge to capture any additional dust produced while emptying the bulk bag.
The hoist and trolley are included as a means to lift the bulk bag into position from the floor without the use of a forklift. The capacities vary based on the application and the units come with a manual or electrically controlled trolley.
The de-weigh option allows the operator to monitor the amount of product being dispensed.
Yes, the UltiMAX™ bulk bag unloader has two options for loading – forklift load and loading using a fixed hoist attached to the frame. The option includes the hoist as well as the upper frame section and supporting I-beam.
The standard UltiMAX™ bulk bag unloader is designed with an internal opening of 60". This generally allows enough room for 48" x 48" square bags to be introduced to the machine. The height of the bulk bags can range from 30" to 75" tall.
The UltiMAX™ bulk bag unloaders are available in 1 Ton and 2 Ton designs standard. Higher capacity units are available as custom designs.
Yes, the UltiMAX™ bulk bag unloader can discharge spouted bags. The untie box option or pinch ring option should be selected for spouted bags.
Yes. An integral dust collection system can be supplied that is either mounted to the UltiMAX™ frame or freestanding.
Yes, with the V-form valve option and the untie box option together, the UltiMAX™ bulk bag unloader allows the user to close the V-form valve, re-tie a partially empty bag and remove it from the machine without having to empty the bag completely.
The pinch ring assembly is open to the operator and provides easy access. The operator pulls the bag outlet spout down onto the tube and clamps the ring manually or pneumatically on top creating a seal. The Untie box option includes a small enclosure with a door and dust collection port. The operator can open the door, untie the bag and close the door to keep dust contained. Used with the V-form valve the untie box can keep hazardous dust away from the operator.
The rate of discharge of bulk bags out of a UltiMAX™ bulk bag unloader is dependent on – bag size, material flowability, loading time, and how the material is being discharged. Typical discharge rates are from a 1-2 bulk bags/hour up to 5-6 bags/hour.
Bulk bags with a solid bottom panel are designed for single use can be unloaded in an UltiMAX™ bulk bag unloader. The unloader needs to be equipped with a knife assembly that tears open the bottom of the bulk bag using the bag weight. The material runs onto a pan and down into the next process.
The flexor paddle option on a bulk bag unloader can be used to release material that has solidified in the bulk bag during transport. The paddles can be manually or automatically activated on a timer.
