Client Background and Market Context
The client is a mid-sized, family-owned snack manufacturer in Mashhad, Iran, operating in the region for over a decade and seeking to expand into branded potato chips. Facing increased demand from regional supermarkets and export partners, the company’s leadership prioritized automation and compliance as core procurement drivers. Their vision is to establish a benchmark plant for consistent quality and food safety, suited for both domestic and GCC export channels.
According to IMARC Group, the Iranian snack food market is valued at over USD 1.2 billion with a CAGR of approximately 6.5 percent. Key competitors include Chitoz, Shadlee, and Golestan. The timing of this project was influenced by rising consumer demand for locally produced, certified snacks, and the growing importance of Halal and ISO 22000 standards for both domestic and export sales.
Pain Points and Procurement Requirements
Before upgrading, the client struggled with inconsistent chip quality, excessive oil absorption, and frequent downtime on legacy semi-automatic lines. Achieving stable high throughput, food safety compliance, and cost-effective production were critical pain points.
- High Throughput: The line must deliver a stable 500kg per h output with minimal unplanned stops.
- Low Oil Absorption Rate: Finished chips must consistently achieve less than 30 percent oil uptake.
- Energy Efficiency: The line should maximize yield per kWh and cubic meter of gas, with heat recovery where possible.
- Halal Compliance: All process and contact surfaces must support Halal certification and traceability.
- Rapid After-sales Support: Engineer response and spare parts supply must be guaranteed within 24 hours for critical issues.
Engineering Solution and Process Description
The process begins with raw potato intake using a stainless steel elevator conveyor (Model: ASM-EC500), designed for gentle handling of Spunta potatoes with 18 to 20 percent starch content. This ensures minimal bruising and optimal sizing for downstream processing.
ال peeling stage utilizes an abrasive roller peeler (Model: ASM-APR500) set for medium abrasion, calibrated to preserve the average size grade and reduce peel waste. Potatoes are then visually sorted and transferred via a vibratory feeder to the slicing machine (Model: ASM-VS500), which uses a precision blade set at 1.5mm thickness for uniform frying and texture.
Washing is performed in a dual-stage bubble washer to eliminate starch and surface contaminants, critical for Spunta variety’s moderate starch release. التبييض follows in a continuous hot water blancher at 85 deg C for 2 minutes, optimizing chip color and reducing acrylamide formation.
After de-watering in a centrifugal dewaterer (Model: ASM-CD400), slices enter the continuous fryer (Model: ASM-FR500), where an oil temperature of 175 deg C is maintained. A PLC control system ensures precise dwell time and temperature, addressing the 18 to 20 percent starch content to achieve the target oil absorption rate.
De-oiling is achieved via a high-speed vibration de-oiler, followed by cooling on a forced-air conveyor. Seasoning is applied in a drum tumbler with adjustable dosing to ensure even flavoring. A metal detector (Model: ASM-MD300) inspects finished chips before automated packing in nitrogen-flushed pillow bags, ensuring ISO 22000 and Halal requirements are met.

On-Site Installation and Commissioning Story
The production line was shipped via Qingdao Port and arrived at Bandar Abbas after 28 days at sea. Customs clearance in Iran was completed within 10 days, and the equipment was transported overland to Mashhad, where it was unloaded and staged for installation with all components accounted for.
Installation took place over two weeks. One notable technical challenge was stabilizing voltage fluctuations during peak summer, with outdoor temperatures reaching 39 deg C and 35 percent humidity. The engineering team installed an inline voltage regulator and upgraded the facility’s main breaker to ensure consistent 220V 50Hz supply, preventing PLC resets and maintaining uninterrupted commissioning.
During trial production, the first batch achieved target throughput and a measured oil absorption rate of 29 percent, with chip breakage below 2 percent. The client was impressed with the crispness and color uniformity, attributing success to the process controls and careful adaptation to local Spunta potatoes.
Compliance and Certification Pathway
The line was engineered from the outset to meet GSO food safety requirements, specifically GSO 1694 and ISO 22000 for process management, as well as Halal certification mandated in Iran. The project team worked closely with a local accredited body to ensure all documentation, traceability, and audit trail requirements were satisfied before start-up.
Key equipment features supporting compliance include الفولاذ المقاوم للصدأ 304 contact surfaces for HACCP and Halal zones, segregated seasoning and packing areas to avoid cross-contamination, and CE-marked PLCs for data logging. All lubricants and process aids were certified food-grade and Halal compliant, while operator training was documented to meet ISO 22000 standards.
Engineer Field Notes
Commissioning this line in Mashhad presented unique challenges due to the local Spunta potato’s moderate 18 to 20 percent starch content and slightly larger average size. We adjusted slicer speed and blanching dwell time to minimize sugar leaching and control chip color, which proved essential for achieving the desired texture and appearance.
During Halal compliance verification, I learned the importance of pre-installation segregation for seasoning and cleaning utensils. A local auditor emphasized full traceability for all process aids, which we documented and labeled accordingly. This lesson reinforced the value of integrating compliance steps into every phase of installation.
For long-term operation in Iran’s hot arid climate, I recommend regular checks on cooling conveyors and maintaining optimal fryer oil turnover, especially during the summer months when ambient temperatures exceed 35 deg C. These steps are critical to preserving chip quality and equipment life.
