Crumb Handling System

When a food manufacturing firm in Sydney had a requirement to feed bulk crumbs mixed with oils out of pallecons and into a process line, they knew they had a challenge on their hands.

The product compacts under its own weight causing it to bridge and rat hole, making it hard to deliver into conveyors.

Fresco Systems was able to prove through a series of product trials they had ability to work with the product. Fresco then designed and quoted a system that would allow the client to reduce the physical handling of the product while maintaining a continuous throughput, thus both reducing costs and improving productivity. The system provided is completely unmanned except for the loading and unloading of the bulk materials.

Fresco Systems design philosophy makes it a natural choice for this type of application – where ergonomics, safety and productivity go hand in hand. For this application it was imperative that all contact materials were manufactured to the highest standard from 316 S/S and incorporating full safety guarding and interlocks to a category 3 level.

The custom designed solution incorporates a hydraulic bin tipper, with a graduated tipping angle to allow an even flow of product through a mesh into the charging hopper. The hopper was specifically designed with an agitator and fluidisers to negate any chance of bridging or flow issues. This then feeds a charging adaptor for the flexible conveyor, which is tuned via a VSD to match the downstream flow requirements.

This complete system had to fit within tight space requirements meeting site specific protocols around operator access to controls and forklift loading of bulk materials.

Fresco systems is the obvious choice when the requirements are for anything that requires thinking outside of the square, with a team of specialist engineers they are able to customise the solutions to cost effectively meet or exceed the clients expectations.

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.
