Client Background and Market Context
The client is a mid-sized snack manufacturer in Cape Town, South Africa with over a decade of experience in local distribution to supermarkets and convenience channels. Seeking to expand market share and improve product quality, the company invested in a fully-automatic potato chips line to replace labor-intensive manual processes. Their procurement was driven by the need for higher throughput, consistent product quality, and strict compliance with South African food safety and Halal standards.
According to Statista, the South African savory snack market was valued at USD 1.2 billion in 2022, with a projected CAGR of 5.1 percent through 2027. Competitors such as Simba, Willards, and Lay’s dominate shelf space, prompting mid-tier brands to differentiate via automation and food safety. The timing was optimal as post-pandemic demand rebounded and regulatory audits intensified.
Pain Points and Procurement Requirements
Prior to the upgrade, the client struggled with inconsistent output, excessive oil retention in chips, and difficulty meeting Halal and food safety audit requirements. Manual frying and packing limited daily capacity and exposed the operation to higher labor costs and compliance risks.
- Stable 300 kg per h Capacity: Required to meet expanding distributor orders and minimize downtime.
- Low Oil Absorption Rate: Target under 30 percent to improve crispness and shelf life.
- Energy Efficiency: Reduce per-kg electricity and gas consumption by at least 10 percent compared to previous setup.
- Halal Compliance: All materials, contact surfaces, and processing steps must be certified Halal.
- After-sales Response: Technical issues must be resolved within 24 hours to avoid production losses.
Engineering Solution and Process Description
The production process begins with raw potato intake, where locally sourced Mondial potatoes (average size grade 60–80 mm, 18 percent starch) are offloaded onto the conveyor-fed destoner washer. This stage removes soil and stones, ensuring a clean raw material feed critical for South African potato profiles.
Next, the brush-type peeler (Model PL-800) removes skins efficiently while minimizing yield loss. The optical sorter then detects and rejects any green or defective tubers, crucial given the natural variability in Mondial crop appearance and size.
Potatoes are then fed into the rotary slicer (Model SL-600), which produces uniform 1.5 mm slices at a throughput of 300 kg per h. The slice thickness and blade speed are optimized for 18 percent starch content, balancing texture and oil uptake.
Slices are washed in a twin-stage water flume to remove surface starch, then passed through a blancher (Model BL-1000) at 85 deg C for 3 minutes. This deactivates enzymes and prevents post-fry browning. The centrifugal dewaterer reduces surface moisture, supporting lower oil absorption in the subsequent fry.
The heart of the line is the continuous fryer (Model FR-1200), operating at 180 deg C with an integrated oil filtration system. Frying time is precisely controlled to achieve target color and texture for Mondial potatoes. Immediately after frying, chips are transferred to a vibratory de-oiling conveyor to remove excess oil.
Chips are then cooled on an air-blast cooling conveyor, seasoned in a drum-type flavor applicator, and passed through a metal detector for safety. The final stage is automatic packing via a multihead weigher and VFFS packer, delivering consistent retail packs ready for distribution.

On-Site Installation and Commissioning Story
The entire line was shipped in four 40-foot HQ containers from Qingdao to Cape Town Port, completing the sea journey in 27 days. Upon arrival in South Africa, customs clearance was completed within a week, and the equipment was unloaded using a dedicated crane team, minimizing handling risks.
Installation commenced during the early autumn season, with ambient temperatures averaging 24 deg C and humidity around 55 percent. The main technical challenge was voltage stabilization, as local supply fluctuated. The engineer team installed an industrial AVR to ensure consistent 230V delivery, thereby protecting sensitive PLC and inverter components. Water pre-treatment was also optimized to address local mineral content, ensuring washing and blanching quality.
During trial production, the first batch achieved a 98.5 percent yield, with oil absorption measured at 28 percent. Chips exhibited excellent crispness and uniform color. The client was especially pleased with the smooth transition from installation to production under real-world Cape Town climate conditions.
Compliance and Certification Pathway
The line was engineered to fully comply with SABS and SANS 885 food safety regulations, as well as Halal processing requirements for the South African market. All design and documentation were prepared in accordance with SANS 885:2011 and IEC 60204-1 electrical safety standards. Halal compliance was verified by an accredited local body, covering both ingredient sourcing and equipment cleaning protocols.
At the equipment level, all food contact surfaces are الفولاذ المقاوم للصدأ 304, and the line includes segregated zones for flavoring to prevent cross-contamination. The PLC control system is CE-marked and supports audit traceability. Oil filtration and waste management modules are designed for easy cleaning, supporting both HACCP and Halal audits.
Engineer Field Notes
Our first priority was tuning the line for locally sourced Mondial potatoes, which have a medium starch content and variable size. We adjusted the slicer blade speed and blanching time to accommodate the 18 percent starch, achieving optimal color without excessive oil uptake. Uniform slicing was crucial for crispness and oil absorption consistency.
During Halal compliance verification, we learned the importance of detailed cleaning logs and ingredient traceability. The local auditor required full documentation of cleaning cycles and supplier Halal certificates, prompting us to upgrade the PLC data logging to provide automated batch records and cleaning validation reports.
For long-term operation in Cape Town’s Mediterranean climate, I recommend frequent monitoring of oil quality and fryer filtration, especially during periods of higher humidity. Regular staff training on cleaning and maintenance is key to sustaining both food safety and product quality.
