Dust Free Bulk Bag Unloading

The use of flexible intermediate bulk containers (FIBC’s) or bulk bags as they are more commonly referred to have many benefits for the transportation and storage of raw materials such as powders and granules.

Fresco Systems have designed a solution for the safe discharging of bulk bags in a clean, dust free environment. This improves production efficiency and eliminates housekeeping issues caused through lesser processes.

Dust Free Bulk Bags are loaded in to the bulk bag unloader by forklift or electrical hoist and trolley. The bags are supported on the massage plates which protect the operator and through agitation will dislodge materials which may have compacted during storage or transport. The spout of the bulk bag is clamped in Fresco’s unique single handed spout clamp providing a dust tight seal that won’t leak or release during the discharge cycle.

As product discharges from the bulk bag into the process below displaced air vents to the integral or central dust collection system. This creates an air curtain at the spout of the bulk bag and a vacuum within the empty bulk bag collapsing the bulk bag so when remove from the bulk bag unloader it can be disposed of without bellowing dust and air into the environment as the operator folds the bag for disposal or recycling.

All Fresco systems bulk bag unloaders are independently load tested and certified as per AS/NZ 1418.

Fresco Systems designs, manufactures and install process system in-house providing a great deal of flexibility with adapting their standard designs to meet each customer’s specific requirements. Fresco Systems can change materials of construction, finishes, heights etc and adapt the discharge of the bulk bag unloader allowing materials from the bulk bag to be directly discharged in to packing machines, flexible or pneumatic conveyors, hoppers etc.

Bulk Bags to Packaging Equipment

More and more of our customers are separating the blending and packaging process.

Where in the past they directly pack from under the blender, they now blend into bulk bags which separate the blending to the packaging process.

This has many advantages including independent scheduling on both operations.

Fresco Systems assist customers by fitting our bulk bag filling head under the existing blenders. Our single hand operated spout clamp and venting system enables quick and dust tight connection between the blender and the bulk bags. The bulk bags will then need to feed a form fill seal machine or any other packaging equipment. The packaging equipment usually provides a start/stop signal which is controlled by its weigh hopper.

Fresco Systems supplies various types and combinations of this system into the industry and recently we supplied an electric hoist type unloader coupled with a flexible conveyor to feed pre-blended flour products into a form fill seal machine. Due to the various type of pre-blend that needs to be fed, Fresco Systems selected the beveled spiral flexible conveyor which is capable to handle difficult products which packs, smears and compacts. This selection combined with the incorporation of vibration and agitation in the charging hopper ensures that the product flows consistently. A hinged hopper cover was also supplied to allow loading of smaller batch products. The start/stop signal from the packaging equipment communicates with our supplied control system which triggers and activates all the required flow aids above including bag massagers and the flexible conveyor.

Our experience and detailed system design ensures that the system was delivered, installed and commissioned with no hassles and all safety requirements to CAT 3 are met satisfactorily.
