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.

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.

Oats Handling System

As part of their expansion plant, a muesli manufacturer contacted Fresco Systems to assist in handling various types of oats to and from bulk bags.

Their processes require batching from bulk bags as raw materials and then filling bulk bags as finished products.

Being a new user to bulk bags, they were concerned with handling oats in bulk bags, in particular breakages and flowability. Fresco Systems recommended the electric hoist type bulk bag unloaders fitted with vibratory trays and metering screw feeders. The electric hoist enables the operator to handle bulk bags from pallet trucks in the process room rather than forklift. Once lifted, the bulk bags then rest securely on the vibratory tray.

The vibratory tray provides acts as a gentle flow aid compared to the paddles of the bag massagers which might damage the products. The spout clamp then seals the bulk bag spouts creating dust tight, secure attachment, totally enclosing the interface between the bulk bags and the feeder hopper below.

To eliminate the risk of breakage, a larger feeder screw was selected with minimal clearance between the screw edge and the outer tube. This eliminates the risk of the product pinching and breaking during feeding. The bulk bag unloaders are on loadcells which enable the operators to key in desired amounts of product to be batched out.

The end result is an effective way of handling and batching fragile products from bulk bags.

At the end of the process, two bulk bag fillers are positioned side by side to allow continuous feeling of bulk bags. The bi directional belt conveyor feeds into a bulk bag while the other filled bulk bag is being replaced. Once the operator connected an empty bulk bag to the fill head and press the ready button, the bag inflators remove creases and folds in the bags which can cause irregular filling of the bag, making it unstable. The bulk bag fillers are also on loadcells and the belt conveyor feeds each station until the desired weight is reached.

Stand alone control systems were supplied with all systems with the capabilities of communicating to the plant PLC.

As Fresco Systems consulted with the client from concept stage, delivery and commissioning of the systems have been seamless and the customer is now discussing further system upgrades increase their capacity.
