When you’re running a food production facility and handling everything from corn flour to quinoa, quick changeover is a commercial necessity. The throughput pressure of a busy packaging line demands it. Cleaning the equipment between batches, using dry or wet clean-in-place (CIP) depending on the material, must be completed quickly and thoroughly to avoid product contamination.
A major national foodservice distributor upgraded its dry food handling and packaging operation with a food grade conveyor system built around the Floveyor Elementa range. The result was faster changeovers, a cleaner and safer operation, and a packaging line that keeps pace with demand.
The challenge: flour processing across a wide material range
The distributor operates several value-added processing facilities across Australia, with ongoing investment in automated handling and packaging equipment. At one facility, the team was managing a production line upgrade and handling a demanding list of dry food materials:
- Corn flour and rice flour
- Potato starch
- Quinoa and chia seeds
- Sunflower kernels
- Sugar
- Cocoa powder
Each material has variable handling characteristics spread across particle size, bulk density, flowability, and allergen status. The team needed a bulk bag unloading and conveying system that could manage this kind of diversity reliably, feed a multi-head weigher consistently, and support quick changeover between product runs, without cross-contamination risk.
The project was part of a broader packaging line upgrade, with the multi-head weigher and VFFS (vertical form fill and seal) packaging machinery supplied by an external machinery partner. Floveyor was brought in by its Queensland partner to provide the conveying solution.
What does a food grade conveyor need to do on a high-changeover packaging line?
The project manager knew what the system had to deliver. Having worked with Floveyor food processing equipment in a previous role, he already had confidence in the technology. The key requirements for the project were:
- Reliable, consistent feed to the multi-head weigher: no blockages, no surging, no starvation
- Food grade design capable of full dry and wet CIP between product runs
- Allergen management supported by fast, contamination-free changeovers
- Safe handling of partially emptied bulk bags, including the ability to stop flow, retie spouts, and restart without spillage
- Compact footprint to fit within the available space of the existing packaging line without major modifications.
- Reduced manual handling for operators.
The solution: Floveyor Elementa range with integrated bulk bag unloader system
Following a discovery consultation and solution modelling, Floveyor supplied a fully integrated bulk bag unloading and conveying system built around the Elementa range. An Elementa conveyor is from Floveyor’s food and beverage product range, designed for low-risk, dry food applications where cleanability and gentle handling are paramount.
Bulk bag unloader: promoting flow and preventing bridging
The bulk bag unloader was configured with two important features for working across a range of powders with different flow characteristics:
- massage paddles to promote consistent material flow
- a spout chamber vibrator to mitigate bridging.
A bag shut-off valve on the bulk bag unloader allows operators to stop flow mid-fill, retie the bag, and carry out changeovers without spills or contamination risk. An electric hoist and monorail system handles the lifting and positioning of bulk bags, freeing up forklifts for other site tasks and reducing manual handling for operators.
How does a screw feeder improve packaging line performance?
A screw feeder positioned under the bulk bag unloader provides the controlled, regulated feed rate the packaging line requires. This is what gives the multi-head weigher the steady, predictable supply it needs to run accurately and efficiently, one of the most common failure points in flour processing and dry food packaging lines. High- and low-level sensors on the packaging machine hopper automatically signal the screw feeder to start and stop, keeping the system balanced and the line running smoothly.
Floveyor Elementa AMC: gentle conveying from feeder to packaging hopper
The Floveyor F4 AMC from the Elementa range lifts product gently from the screw feeder up to the packaging machine hopper. Using FloDisc® Technology, the AMC conveys material in a fully enclosed, dust-controlled environment, protecting the integrity of the product and the health and safety of the operators. An Elementa is an excellent choice for low-risk applications where a hygienic conveyor is not required.
An electric rope tensioner reduces preventive maintenance time by approximately 50%, which matters in a high-changeover environment where downtime is costly. Equipment condition monitoring is achieved with low-speed sensors and bearing temperature monitoring sensors to check conveyor health continuously, flagging potential issues before they escalate into unplanned stoppages. This protects both upstream and downstream food processing equipment from cascade shutdowns.

How does the Elementa range support allergen management and quick changeover?
Allergen management was a critical requirement for this project. The food grade conveyor design supports both dry and wet CIP, giving operators the flexibility to choose the right cleaning method for each product transition. BFM Flexi connections at each interface provide a fully sealed connection that can be removed quickly for cleaning.
Safety interlocks and guarding are fitted to all maintenance and cleaning access points, with tool-free quick-release clips on guards for fast, safe access. The result is a food grade conveyor system where quick changeover is engineered from the ground up, not retrofitted as an afterthought.
For guidance on allergen management in food manufacturing, the Food Standards Australia New Zealand (FSANZ) allergen resources provide a useful reference for manufacturers.
Compact footprint, seamless integration
The new system was designed to fit within the existing packaging line layout, integrating with the multi-head weigher and VFFS machinery without requiring major modifications to the surrounding equipment. For plant managers working with constrained floor space, this kind of modular, fit-for-purpose design is often the difference between a practical solution and one that creates new problems.
Why the Floveyor Elementa range won the tender
Several factors separated Floveyor from international competitors. As an Australian manufacturer, Floveyor offered significantly shorter lead times, a practical advantage that helped the project team meet a tight schedule. Floveyor’s Queensland partner provided experienced onsite support through installation and integration.
What ultimately stood out was the quality of the solution. Floveyor listened carefully to the operational pain points and addressed each one directly:
- smooth, reliable material flow from bulk bags
- rapid changeovers that support allergen management
- operator-friendly handling and cleaning
- built-in features that reduce unplanned downtime.
The project manager’s prior experience with Floveyor reinforced confidence in a Floveyor choice at the decision-making stage.
The outcome: a packaging line built for throughput and food safety
The Floveyor Elementa range delivered a bulk bag unloading and conveying system that met every project objective within the compact footprint of an existing packaging line. And they were able to do it with minimal disruption to surrounding equipment.
The food distributor now operates a dry food handling system that manages a wide range of powders consistently and safely, supports quick changeover, eliminates contamination between batches and gives operators a cleaner, safer working environment. The electric hoist and monorail have simplified bulk bag handling. The sensors and interlocks have reduced the risk of unplanned stoppages. Floveyor’s food grade Elementa range excels for the long term in a demanding production environment.
Frequently asked questions
Quick changeover in food processing refers to the ability to switch a production or packaging line from one product to another rapidly and without risk of cross-contamination. In dry food handling, this typically means cleaning conveying and feeding equipment between product runs, especially when one or more materials contain allergens. A food grade conveyor design with CIP capability and tool-free access points such as the Floveyor AMC is central to achieving reliable, quick changeover. Features like tool-free guard removal and bag shut-off valves also help operators execute changeovers quickly and thoroughly.
Allergen management on a shared packaging line requires a combination of procedural controls and equipment design. On the equipment side, fully enclosed conveying systems, sealed flexible connectors, and CIP capability reduce the risk of allergen carry-over between batches. FSANZ provides regulatory guidance for Australian food manufacturers on allergen labelling and management.
A bulk bag unloader (also called a big bag discharger or FIBC unloader) is a bulk material handling system to support and empty large flexible intermediate bulk containers, typically holding 500 kg (1,100 lb) to 1,500 kg (3,300 lb) of powder or granular material. Product flows out through the bag spout into a hopper or feeder below. Features like massage paddles, spout chamber vibrators, and bag shut-off valves help manage flow, prevent bridging, and allow safe mid-fill changeovers.
An aero-mechanical conveyor uses a rope and disc assembly moving at high speed inside a sealed tube to create an airstream that suspends and transports powder or granular material. AMCs are well-suited to food processing applications because they are:
- fully enclosed to control dust and contamination
- gentle on friable materials
- capable of vertical and steep-angle conveying
- easy to clean
