Client Background and Market Context
The client, a mid-sized snack manufacturer in Tehran, Iran, operates several food processing lines and was seeking to diversify its product portfolio with high-quality compound potato chips. Facing rising demand in the urban snack market, the company required a robust, fully-automatic solution to ensure consistent output and compliance with Halal and ISIRI standards. Their procurement motivation centered on capturing a larger share of the fast-growing snack segment while modernizing production capabilities to compete with established brands.
According to Statista, the Iranian snack market is valued at USD 2.1 billion with a CAGR of 6.8 percent (2023-2027). Key competitors include Chitoz, Shadmehr, and Behrouz. The timing of this investment was driven by post-pandemic consumer shifts toward packaged snacks and the need for local content compliance in procurement. This context underscores the strategic importance of high-efficiency, certified lines for manufacturers in Iran.
Pain Points and Procurement Requirements
Prior to this project, the client struggled with inconsistent product quality, excessive oil absorption, and frequent compliance audit failures on their legacy semi-automatic line. Their main pain point was achieving stable high throughput while meeting Halal and ISIRI standards without excessive operating costs or production downtime.
- High Capacity: The line must reliably process 500 kg/h of compound potato chips with minimal downtime.
- Low Oil Absorption Rate: Finished product must not exceed 23 percent oil content to meet ISIRI 3206.
- Energy Efficiency: Total energy consumption must remain below 0.08 USD per kWh to control operating costs.
- Halal Compliance: All contact surfaces and process flows must support Halal certification with segregated zones.
- Rapid After-Sales Support: The supplier must provide a 24-hour response window for technical issues post-commissioning.
Engineering Solution and Process Description
The production process begins with raw potato intake, where Spunta and imported Atlantic varieties are unloaded, sorted, and stored in a temperature-controlled bin. The potato peeling machine (Model PL-800) employs soft-abrasion rollers to minimize starch loss, crucial for the local 18–20 percent starch content. Size grading follows, using a vibratory grader tuned to accommodate the 60–80 mm average local tuber size.
Next, the slicing and washing stage utilizes the SL-500 rotary slicer with adjustable blade thickness from 1.2–2.4 mm. Slices are immediately conveyed to a multi-stage washer with high-velocity jets to remove surface starch and reduce acrylamide formation. This step is particularly important for Iranian potatoes, which can have variable starch distribution.
Blanching is performed in a continuous belt blancher (BL-600) at 75–80 deg C for 90 seconds, optimizing enzyme inactivation without over-softening. The de-watering centrifuge (DW-400) then reduces surface moisture to below 2 percent, ensuring efficient frying and minimizing oil uptake.
The frying process uses a continuous fryer (FRY-1000) with precise temperature control at 175 deg C. Oil flow and turnover are tightly managed to maintain product color and minimize oxidation. A vibration de-oiler follows, reducing the final oil absorption rate to an average of 22.5 percent, which is below the ISIRI 3206 maximum.
Post-frying, chips are cooled in a spiral cooling tunnel to ambient temperature, then seasoned in a drum flavoring system with dust extraction to ensure even coating. Metal detection is achieved using a CE-marked detector (MD-300) with 0.8 mm Fe sensitivity. The final stage is automatic packing with a vertical FFS machine supporting up to 60 bags per minute, ensuring product shelf life and compliance with local labeling laws.

On-Site Installation and Commissioning Story
The equipment was shipped from Qingdao, China to Bandar Abbas over a period of 23 days via sea freight. Upon arrival, customs clearance in Iran proceeded smoothly owing to pre-arranged ISIRI documentation. Unloading at the Tehran facility was completed within 36 hours, with all modules staged for phased installation.
Installation week was marked by a technical challenge—voltage fluctuations in the local grid caused PLC resets during the initial dry runs. Our engineering team installed a 30 kVA stabilizer and reconfigured the main distribution panel to ensure stable 220V 50Hz supply. Additionally, ambient humidity averaged 32 percent and the temperature was 27 deg C, requiring adjustment to the cooling tunnel’s airflow to maintain crispness.
During trial production, the first batch yielded an average oil absorption rate of 22.5 percent and throughput of 502 kg/h. The client was impressed by the consistent texture and color. These results were achieved under typical Tehran spring weather, with low humidity supporting optimal de-oiling and seasoning.
Compliance and Certification Pathway
The line was engineered for full compliance with ISIRI 3206 (compound potato chips), HACCP, and Halal food processing requirements. All process documentation, traceability protocols, and ingredient sourcing were validated during the ISIRI audit. The Halal certification required process segregation and ingredient control, while HACCP focused on critical control points in frying and packing. Reference: Codex Alimentarius, ISIRI 3206.
Equipment features supporting compliance included stainless steel 304 contact surfaces, food-grade conveyor belts, CE-marked PLC controls, and automatic oil filtration. Dedicated zones and color-coded utensils ensured Halal segregation. All electrical and automation panels carried CE and ISIRI marks, supporting both local and export requirements.
Engineer Field Notes
Adapting the machinery for Spunta and Atlantic potatoes with 18–20 percent starch content required fine-tuning the blancher dwell time and slicer blade clearance. The local potatoes’ moderate starch and variable size (mostly 60–80 mm) meant we had to calibrate the grader and washer to prevent starch build-up and ensure even frying. Inconsistent slice thickness can raise the oil absorption rate, so the SL-500 slicer’s calibration was mission-critical.
During Halal compliance verification, we learned that even minor cross-contact risks must be addressed. We implemented a documented cleaning protocol and used physical dividers in the seasoning and packing zones. This lesson reinforced the importance of designing for both regulatory and cultural expectations in Iran.
For the hot, arid climate of Tehran, I recommend frequent maintenance checks on the cooling tunnel and de-oiling system, especially during the dry season when ambient humidity drops below 35 percent. This helps maintain chip crispness and prevents seasoning clumping. Periodic oil filtration is also essential to prolong oil life and keep product quality consistent year-round.
