Bulk Bag, Small Bag & Drum Handling

Powder often enters and leaves a plant in super sacks, small bags, and drums. Efficiently and effectively handling these containers is crucial. Every connection between a container and the process is a chance for dust to escape and product to be lost. GQI specs this equipment, complete solution or legacy system upgrade, based on your application: the product, the container actually in service, the containment level required, and the equipment on the other side.

The GQI Approach

Designed Around the Container

FIBC connections · bag-dump stations · drum handling, specified & delivered through GQI

A container handling system works best when it is designed precisely for the container showing up at the facility. That's why GQI's specification starts with the bag or drum itself, spout diameters, liner, loop type, full and empty dimensions, in conjunction with material characteristics and peripheral process demands.

Filling and discharging, engineered separately
Sized to the actual bag: spout, liner, loops, clearance
304 / 304L / 316 / 316L stainless or carbon steel
Weld finishes from industrial to pharma electropolished
Executions for hazardous dust & explosivity concerns
High-containment options up to OEB-rated systems

Application: Emptying Bulk Bags

Bulk Bag Discharging

FIBC discharge connections: bottom spout to your process

Discharging connects the bottom spout of a full FIBC to whatever comes next: a hopper, a screw or rotary feeder, a conveyor. The connection is sized to the outlet spout of the bag actually in service, and the options are chosen for the dust behavior of the product: dedusting connections pull away displaced air, liner clamps control the inner liner, and exchangeable inner tubes let one station serve bags with different outlet diameters.

Sized to the outlet spout: diameter, length above & below tie
Exchangeable inner tube for varying FIBC outlets
Liner clamping device for lined bags
Dedusting / evacuation connection
Dust filter or filter retrofit kit
WIP: integrated wash-in-place spray nozzle

Application: Filling Bulk Bags

Bulk Bag Filling

FIBC fill connections: fill head to the top spout

Filling connects a fill head to the top spout of an empty FIBC. The fill connection mounts under the equipment doing the dosing (a fill head, feed system, or weigh frame), so GQI specs it against the inlet spout diameter, the bag construction (loops, liner), and the full-bag weight and dimensions your process produces. The same containment options apply: dedusting to handle displaced air, hazardous-dust execution where explosivity concerns demand it.

Sized to the inlet (fill) spout diameter
Mounts under fill heads, dosing / feed & weigh frames
Bag construction accounted for: loops, liner, weight
Dedusting / evacuation of displaced air
Air-regulator kit for pneumatic functions
Hazardous-dust execution available

Small-bag dump station for manual sack emptying

Application: Small Bags, Drums & Kegs

Small Container Handling

Bag-dump stations & drum filling, discharging & tipping: sacks ~25 kg / 50 lb · drums 30 gal, 55 gal / 200 L & custom

Small containers cover two jobs, filling and discharging, and GQI specs both. When product arrives in sacks an operator can lift, a bag-dump station keeps the dust at the station instead of in the room, specced around the sacks, bags per hour, and what the station feeds. Drums and kegs discharge into the process with a tipper or lift column, a containment cone at the connection, and dust extraction where the product needs it; or fill to a target weight with dust containment during the fill and drum indexing where throughput demands it. Dust control scales from a simple hood to an integral filter to full high-containment execution.

Integral dust filter, hood or extraction / vent connection
De-bagging grate & bag compactor for empty sacks
Open-top, tight-head & fiber / keg drums
Full inversion / tipper & lift column / hoist
Fill head with dosing / weigh control & fill accuracy
Drum clamp, indexing / turntable & lid handling
Feeds hoppers, screeners, conveyors & pneumatic lines
Food-grade / FDA · hazardous-dust builds · mobile on castors

Containment

High Containment, When the Product Demands It

OEB-driven containment: up to glovebox systems

Some products set the containment level for you. Where an OEB (occupational exposure band) requirement applies, GQI offers high-containment FIBC connection systems, such as the Hecht HCVS, and high-containment / glovebox executions of bag-dump and drum stations. The specific system is selected with GQI engineering against your OEB level and hazardous-area classification.

High-containment FIBC connection systems (e.g. Hecht HCVS)
High-containment / glovebox bag-dump & drum options
Specified against your OEB level
Class / Div / Group execution for hazardous dust

Built to the Duty: Alloys, Finishes & Seals

Materials of construction are locked in at specification (contact and non-contact surfaces separately) so hygienic, abrasive, and hazardous-area duties get the build they need.

Alloys, Contact & Non-Contact

304 / 1.4301, 304L, 316, 316L stainless or carbon steel, specified separately for product-contact and non-contact surfaces.

Weld Finishes to Pharma Grade

From industrial as-welded through sanitary ground-flush, dairy crevice-free (Ra ≤ 0.8 µm), and pharma (Ra ≤ 0.5 µm / electropolished).

Seals & Elastomers

EPDM (FDA), platinum-cured silicone (FDA), nitrile, FKM / Viton, PTFE / FEP, and polyurethane. Every acceptable option captured at specification.

Sleeves & Sock Fabrics

PU-coated polyester, food-grade / FDA PU, antistatic / conductive (Type C), and PTFE-coated fabrics for the flexible elements of the connection.
