Client Background and Market Context
The client is a mid-sized snack manufacturer based in Riyadh, Saudi Arabia, operating for over a decade with a focus on potato- and corn-based snacks. Their procurement initiative was driven by the need to modernize production, reduce labor dependency, and ensure compliance with Halal and GSO standards to access high-growth retail channels across the GCC region.
The Saudi snack food market is valued at USD 1.9 billion with a 6.3 percent CAGR (Statista, 2023). Key competitors include Al-Batal, Al-Jazira, and Lay’s. The timing was advantageous due to rising demand for locally produced, certified snacks, and expanding distribution networks within Saudi Arabia and neighboring Gulf states.
Pain Points and Procurement Requirements
Prior to upgrading, the client struggled with inconsistent product quality, excessive oil uptake, and frequent downtime on legacy semi-automatic lines. Meeting Halal and GSO certification for retail and export was a recurring challenge, compounded by high energy costs and slow after-sales response from previous suppliers.
- High Throughput: Line must reliably process 500kg per h of local Spunta potatoes with minimal manual intervention.
- Low Oil Absorption Rate: Finished chips should not exceed 32 percent oil content to meet cost and shelf life targets.
- Energy Efficiency: Total power and gas consumption must be optimized for 0.08 USD per kWh electricity and 0.32 USD per cubic meter gas prices.
- Halal and GSO Compliance: All process zones, contact surfaces, and ingredients must be certified for Halal and meet GSO 1694/2016 standards.
- Rapid After-Sales Support: On-site and remote troubleshooting must be available within 24 hours to minimize downtime.
Engineering Solution and Process Description
The production process begins with raw potato intake and automatic destoning using the ASM-PD500 model, designed to handle Spunta potatoes averaging 140g per tuber and 18 percent starch. This ensures initial debris removal and reduces mechanical wear downstream.
Next, peeling is performed by the ASM-AP500 abrasive peeler, which minimizes surface damage and starch loss. Optical sorting follows, using the ASM-OS200 to reject under- or over-sized tubers, a critical step given the variable size and high dry matter content of local potatoes.
Slicing employs a high-speed rotary slicer (ASM-RS1000) with adjustable thickness (1.3mm to 2.0mm), calibrated for optimal crispness retention and uniform frying. Washing uses a multi-stage hydro cyclone to remove surface starch, preventing excessive oil absorption in subsequent frying.
Blanching is executed in the ASM-BL500 continuous water blancher at 85 deg C for 2.5 minutes, which ensures enzymatic inactivation and a bright chip color. De-watering is handled by a centrifugal de-watering system (ASM-DW300) to reduce surface moisture below 2 percent, critical for oil management.
Frying utilizes the ASM-FR500 continuous fryer with automatic oil filtration and precise temperature control at 175 deg C. The system achieves less than 32 percent oil absorption by synchronizing conveyor speed and oil replenishment. De-oiling is performed by a vibration de-oiler to further reduce surface oil.
After cooling (ASM-CL400 air cooler) and seasoning (ASM-SN300 drum system), chips pass through a metal detector (ASM-MD100) before automated packing in nitrogen-flushed bags using the ASM-PK500 VFFS packer. Each stage is PLC-controlled for traceability and batch integrity.

On-Site Installation and Commissioning Story
The line shipped from Qingdao, China to Jeddah Islamic Port, with a transit time of 19 days. Customs clearance in Saudi Arabia was completed within 5 days due to pre-arranged documentation and Halal certification checks. Equipment was unloaded and delivered by road to the Riyadh site, arriving intact and on schedule.
Installation spanned 12 days, during which the team encountered a voltage stability challenge due to local grid fluctuations. The issue was resolved by installing an industrial-grade AVR (Automatic Voltage Regulator), protecting sensitive PLC and VFD components. Water treatment was also optimized for the hot arid climate and 35 percent average humidity, ensuring consistent blanching and washing performance.
During the trial production phase, the first batch achieved a 99.6 percent yield and consistent chip color, with oil absorption at 29.8 percent. The customer praised the crispness and throughput stability, noting that the line maintained full output despite ambient temperatures exceeding 42 deg C during commissioning week.
Compliance and Certification Pathway
The line was designed to meet Gulf Standards Organization (GSO) 1694/2016 food safety requirements and Halal certification. All process documentation and materials traceability were implemented to facilitate Saudi FDA and Halal audits. Special attention was given to ingredient segregation and allergen management per GSO 9/2013.
Equipment features include stainless steel 304 food contact surfaces for HACCP and GSO compliance, dedicated Halal ingredient zones with color-coded bins, and CE-marked PLC controls for export readiness. Cleaning-in-place (CIP) systems and batch traceability further support certification and audit requirements.
Engineer Field Notes
During commissioning, we quickly realized that the local Spunta potatoes, while generally uniform in size, had a slightly lower starch content (18 percent) than anticipated. This required adjusting the slicing thickness to 1.5mm and reducing blanching time by 15 seconds to prevent darkening in the final product.
One critical lesson was the importance of strictly isolating Halal zones during ingredient handling and cleaning. Our team worked closely with the client’s Halal supervisor to implement color-coded utensils and train operators on batch changeover protocols, ensuring full certification at the first inspection.
For long-term operation in Saudi Arabia’s hot arid climate, we recommend biweekly checks on the cooling and ventilation systems, especially during summer months when ambient temperatures can exceed 42 deg C. Maintaining humidity below 40 percent in the packing area is also vital for chip crispness.
