Client Background and Market Context
The client, a mid-sized snack manufacturer based in Lima, Peru, operates across the Andean region, supplying major supermarket chains and foodservice distributors. With a recent capital investment round, the company sought to expand its potato chips offering using a fully-automatic line to ensure consistent product quality, higher throughput, and compliance with export and Kosher standards. Their procurement motivation was driven by the need to compete with major brands while responding to increased demand for hygienic, certified snacks.
According to Statista, the Peruvian savory snacks market was valued at USD 1.1 billion in 2023, with a projected CAGR of 6.3 percent through 2027. Key competitors include Frito Lay Peru, La Ibérica, and San Jorge. The timing was strategic as the market shifts toward higher regulatory scrutiny and consumer preference for certified, export-ready potato chips.
Pain Points and Procurement Requirements
Prior to this investment, the client struggled with inconsistent product texture, high oil absorption, and compliance gaps with INVIMA and Kosher standards. Their legacy semi-automatic line could not meet supermarket specifications or ensure reliable throughput, especially during humidity spikes in Lima’s coastal climate.
- High Throughput Capacity: Must reliably deliver 500 kg/h output with minimal downtime.
- Low Oil Absorption Rate: Final chips must not exceed 28 percent oil content to meet market expectations.
- Superior Energy Efficiency: Total energy use per kg must be reduced by at least 10 percent compared to previous setup.
- Kosher Compliance: All process steps and materials must support Kosher certification for export and local market access.
- Rapid After-sales Response: Service team must guarantee 12 hour maximum response to technical issues.
Engineering Solution and Process Description
The process begins with raw potato intake, where automatic conveyor-fed hoppers are used to minimize manual handling and preserve the quality of the local Innovator potato variety, known for its 20 percent starch content and medium-large size. The roller brush washer-peeler (Model ASM-WP600) removes soil and peels efficiently, adjusting brush speed for optimal skin removal without excessive yield loss.
Next, optical sorting with the ASM-OS300 ensures defective or green potatoes are ejected, critical for consistent chip color and food safety. The multi-blade slicer (ASM-SL500) slices potatoes to a uniform 1.4 mm thickness, with variable speed drive to adapt to the average size grade of Peruvian potatoes.
The vortex washing system (ASM-VW400) removes surface starch, which is essential for Innovator potatoes with higher starch content to prevent clumping and ensure crispness. Following this, hot water blanching (ASM-BL350) at 85 deg C for 2 minutes inactivates enzymes, preserves light color, and reduces acrylamide formation.
De-watering is performed by a centrifugal de-watering unit (ASM-DW500), optimizing for 60 seconds at 900 rpm to achieve a surface moisture content below 6 percent. This step directly impacts oil absorption and final chip texture.
In the continuous frying system (ASM-FR700), chips are fried at 175 deg C for 3.5 minutes with precise oil flow control and automatic filtration. The system’s heat recovery design reduces energy usage, and the de-oiling conveyor (ASM-DO350) ensures excess oil is removed, supporting the target oil absorption rate.
Chips are then cooled on a vibration cooling conveyor (ASM-CC350) to ambient temperature, seasoned in a tumble drum (ASM-SN300), and passed through a multi-frequency metal detector (ASM-MD150) for food safety. Finally, the vertical form-fill-seal (VFFS) packer (ASM-PK320) ensures hermetic, high-speed packaging with gas flushing to preserve crispness.

On-Site Installation and Commissioning Story
The equipment was shipped from Qingdao, China to Callao Port in 27 days via ocean freight. After prompt customs clearance in Peru, the line was delivered to the Lima site and unloaded using local crane services. All modules arrived intact, and pre-commissioning checks began immediately.
Installation took place over one week. The primary challenge was stabilizing the 220V 60Hz power supply, as minor voltage fluctuations affected the PLC control panel. The engineering team installed an industrial-grade voltage stabilizer and adjusted the water treatment system to address 60 percent ambient humidity, which can affect chip crispness during packaging. These measures ensured both equipment reliability and product quality in Lima’s coastal environment.
During trial production, the first batch achieved a consistent 27.5 percent oil absorption rate and stable chip color. The client was impressed with the line’s throughput and the crispness of the finished product, even as ambient temperatures reached 22 deg C and humidity was above 60 percent. The line passed all performance acceptance tests on schedule.
Compliance and Certification Pathway
The production line was engineered to fully comply with INVIMA food safety regulations and HACCP principles, as well as Kosher requirements for the Peruvian and export markets. All process documentation and validation records were prepared in accordance with INVIMA Resolution 719/2015 and Codex Alimentarius standards. Cultural compliance for Kosher was ensured by segregating all non-plant-based lubricants and providing detailed traceability for all ingredients and contact surfaces.
Equipment features supporting certification included stainless steel 304 food contact surfaces for HACCP and Kosher hygiene, color-coded sanitation zones, and CE-marked PLC controls for future EU export readiness. Automatic CIP (Clean-in-Place) systems were implemented to facilitate both INVIMA audits and routine Kosher inspections.
Engineer Field Notes
Adapting the process to the Innovator potato variety was crucial. With a 20 percent starch content and medium-large size, we fine-tuned the blanching and de-watering steps to prevent excessive oil absorption and ensure crispness. The 1.4 mm slicing thickness proved optimal for both texture and frying time.
During Kosher compliance verification, we learned the importance of segregating all non-plant-based lubricants and maintaining strict traceability from raw intake to packing. Routine validation of the automatic CIP system was essential for passing both INVIMA and Kosher audits.
For long-term operation in Lima’s humid subtropical climate, we recommend regular checks of the water treatment and de-oiling systems, especially during the rainy season, to maintain chip crispness and minimize microbial risks. The voltage stabilizer also proved invaluable for consistent PLC performance.
