Client Background and Market Context
The client is a mid-sized snack food producer in Melbourne, Australia, operating in the premium chips and healthy snacks segment. Facing rising demand for locally-sourced, clean-label sweet potato chips, they sought a fully-automatic line to scale production, meet Halal requirements, and ensure EU Regulation 1169 compliance for both domestic and export channels.
According to Statista, the Australian savory snacks market was valued at USD 3.2 billion in 2023 with a 4.6 percent CAGR. Major competitors include Smith’s, Red Rock Deli, and Tyrrells. Commissioning in Q1 2024 allowed the client to capitalize on seasonal demand and new retail contracts while leveraging rising consumer interest in alternative chips.
Pain Points and Procurement Requirements
Prior to this project, the client struggled with inconsistent throughput, excessive oil absorption, and lengthy changeover times on legacy semi-automatic lines. These issues resulted in higher operating costs and limited ability to meet large retail orders, especially during peak demand cycles.
- Capacity Upgrade: Required minimum 1000 kg per h sweet potato chips output to fulfill new supermarket contracts.
- Oil Absorption Rate Control: Targeted finished product oil content below 29 percent to ensure crispness and shelf life.
- Energy Efficiency: Needed to reduce electricity and gas consumption per kg by at least 10 percent.
- Halal Compliance: All contact surfaces and processes must support Halal certification for domestic and export sales.
- After-Sales Response: Required guaranteed spare parts and remote support response within 12 hours.
Engineering Solution and Process Description
The process begins with raw sweet potato intake, where a belt-type elevator feeds tubers into the automatic washing and peeling machine (Model AP-900). This unit uses a combination of abrasive rollers and water spray to remove soil and skins efficiently, critical for Lady Rosetta sweet potatoes with their 22 to 24 percent starch and delicate skin.
After peeling, optical sorting (Model OS-350) eliminates defective or undersized tubers. The size grading ensures only Grade A (60-80mm) sweet potatoes enter the rotary slicer (Model RS-1200), producing uniform 1.5 mm slices for consistent frying and texture.
The sliced sweet potatoes move through a multi-stage washing line with high-pressure water jets to remove excess starch, followed by a vibration dewatering unit. This step is vital for oil absorption control, as higher residual surface starch would otherwise increase oil uptake in the final product.
In the continuous blanching machine (Model CB-1000), slices are blanched at 85 deg C for 90 seconds to deactivate enzymes and maintain color. The subsequent centrifugal dewatering machine (Model CD-800) reduces surface moisture to below 8 percent, optimizing the chips for frying.
Frying occurs in a continuous oil fryer (Model CF-1200) with precise PLC temperature control at 175 deg C. The system uses a multi-zone filtration and automatic oil replenishment to maintain oil quality and minimize oxidation, especially important for sweet potato’s high sugar content.
After frying, chips pass through a vibration de-oiling conveyor and then a cooling tunnel to stabilize texture and prevent condensation. Seasoning tumblers apply flavorings uniformly. A metal detector (Model MD-500) ensures food safety before the chips are packed by the vertical form-fill-seal machine (Model VFS-520) at up to 60 bags per min.

On-Site Installation and Commissioning Story
The production line shipped from Qingdao, China to Port Melbourne via sea freight, covering a distance of 18 days. Upon arrival, customs clearance in Australia was completed within 5 working days, thanks to pre-arranged documentation and local agent support. Unloading at the client’s Melbourne facility proceeded smoothly, with all crates inspected for transit damage.
Installation began the following week. The main technical challenge was stabilizing the 240V 50Hz power supply under variable load, which affected the PLC response time. Our engineering team installed a dedicated voltage stabilizer and upgraded the grounding system to eliminate fluctuations. Additionally, a brief spell of temperate autumn weather, averaging 13 deg C with 70 percent humidity, required fine-tuning of the cooling tunnel to prevent chip softening.
During trial production, the first batch of sweet potato chips achieved 99.2 percent yield and oil content below 29 percent, with excellent crispness and no off-flavors. The client’s QA team approved the batch for immediate shipment to retailers. These results validated the engineering design and process control under real-world Australian conditions.
Compliance and Certification Pathway
From the outset, the production line was engineered to comply with EU Regulation 1169 for labeling and traceability, as well as HACCP and Halal requirements for the Australian market. All documentation and process validation were aligned with BRC and Codex Alimentarius standards. Segregated ingredient handling, allergen control, and automated batch traceability were implemented to meet these stringent requirements.
At the equipment level, all food contact surfaces use keluli tahan karat 304, with welded seams and easy-clean design for HACCP compliance. The PLC system is CE-marked and supports digital traceability logs. The line layout incorporates segregated zones to support Halal certification, with clear visual demarcation and documented cleaning protocols. These features were verified during the third-party audit and cited as best practice.
Engineer Field Notes
Adapting the line to Lady Rosetta sweet potatoes, which have a 22 to 24 percent starch content and average size grade of 65 mm, required fine-tuning the slicing and blanching parameters. We found that a slightly longer blanch at 85 deg C, followed by aggressive centrifugal dewatering, produced consistently crisp chips with controlled oil absorption.
During the Halal compliance review, we learned the importance of documenting every cleaning cycle and maintaining physical separation of packaging materials. The local auditor flagged a minor issue with flavoring storage, which we resolved by introducing color-coded bins and digital inventory logs.
For long-term operation in Melbourne’s temperate climate, I recommend regular calibration of the cooling tunnel and humidity sensors, especially during seasonal transitions. This prevents moisture condensation and ensures consistent product crunch.
