Client Background and Market Context
The client is a mid-sized snack manufacturer in Mexico City, operating for over 12 years in the regional potato and corn snack sector. Facing increased demand from supermarket and convenience chain buyers, the company sought to automate its potato chips production, aiming for higher throughput, tighter quality control, and compliance with evolving NOM food safety standards. Their procurement was driven by both capacity expansion and the need to meet stricter certification requirements for distribution.
The Mexican snack market is valued at over USD 6.7 billion with a 5.9 percent CAGR according to Statista. Major competitors include Sabritas, Bokados, and Barcel. The timing of this investment aligned with post-pandemic demand recovery and supply chain shifts, giving the client a strategic window to capture market share with higher quality and certified products.
Pain Points and Procurement Requirements
Prior to this project, the client struggled with inconsistent product quality, high oil usage, and labor-intensive manual steps. Meeting new NOM certification and optional Kosher requirements further complicated their process. They required a solution that could ensure stable output, cost control, and rapid after-sales support.
- Throughput Capacity: The line must deliver a consistent 300 kg per h output to meet order volumes during peak demand.
- Oil Absorption Rate: Finished chips must remain below 24 percent oil content for health and labeling compliance.
- Energy Efficiency: Total electricity and gas consumption must be reduced versus legacy equipment, targeting under 0.10 USD per kg.
- Kosher Compliance: All food contact materials and process steps must allow for optional Kosher certification.
- After-Sales Response Time: Service response within 24 hours is mandatory to minimize unplanned downtime.
Engineering Solution and Process Description
The raw potato intake system uses a stainless steel elevator (ASM-E300) designed for the Innovator variety, which averages 21 percent starch content. This ensures gentle handling and prevents tuber bruising that could increase sugar and darken chips.
Peeling is performed by a brush roller peeler (ASM-P320) with adjustable water spray. This model achieves over 98 percent skin removal with minimal potato loss, tailored to the medium size grade (80-120g) typical in Mexican supply chains.
Sorting and slicing follow, using a vibratory grader (ASM-G250) and centrifugal slicer (ASM-S300) equipped with 1.5mm blade sets. The slicer is calibrated for Innovator potatoes, optimizing cut uniformity and minimizing starch leaching.
The washing and blanching system features a dual-stage washer (ASM-W220) and a continuous blancher (ASM-B200). Washing removes free starch, while blanching at 80 deg C for 2 minutes reduces reducing sugars and stabilizes chip color, critical for potatoes with 21 percent starch.
De-watering is accomplished by a centrifugal de-watering machine (ASM-D150), reducing surface moisture to less than 4 percent. This step is vital for oil absorption control and crispness retention.
Жарка is managed by a continuous fryer (ASM-F350) with a 500L oil tank, operating at 180 deg C. The PLC-regulated temperature and oil circulation system ensure even cooking and precise oil uptake.
De-oiling and cooling follow, using a vibration de-oiler (ASM-DO100) and cooling conveyor (ASM-C100). These stages achieve the target oil absorption rate and prepare chips for seasoning.
Seasoning is handled by a drum tumbler (ASM-T80) with variable speed control for uniform flavor application.
Metal detection and packing are the final steps, with a metal detector (ASM-MD60) and vertical form-fill-seal (ASM-PK200) machine, ensuring food safety and high-speed bagging at up to 30 packs per minute.

On-Site Installation and Commissioning Story
The production line was shipped from Qingdao to Veracruz port in 23 days, with customs cleared in Mexico within 4 days. The team coordinated local transport to the Mexico City facility, where unloading was completed efficiently due to pre-arranged staging and bilingual logistics support.
Installation spanned one week, during which the main technical challenge was stabilizing 220V 60Hz voltage supply amid fluctuating city grid conditions. Our engineers deployed a voltage regulator and collaborated with the factory’s electrical team for seamless integration. Additionally, water treatment was fine-tuned to address high local hardness, preventing scale in the blancher and fryer.
The trial production phase coincided with a humid season, with ambient temperatures around 22 deg C and 62 percent humidity. First batch output met all quality targets, with 99.2 percent yield and crispness exceeding client expectations. The customer praised the rapid setup and training, noting minimal adjustment time for operators.
Compliance and Certification Pathway
The line was engineered to meet NOM-251-SSA1-2009 for food safety, HACCP protocols, and optional Kosher requirements. All process steps and documentation were audited for compliance, with validation by third-party inspectors as mandated by INVIMA for food processing equipment in Mexico.
Equipment-level features supporting certification included нержавеющая сталь 304 food contact surfaces, segregated material flow for allergen control, and CE-marked PLC systems. Kosher compliance was facilitated through dedicated cleaning cycles and certified lubricants, while HACCP points were mapped and monitored via the integrated control system.
Engineer Field Notes
Adapting the line to Innovator potatoes was straightforward due to their 21 percent starch content and medium size grade. We adjusted blanching time and slicing thickness for optimal color and crispness, achieving consistent results even with seasonal supply variations.
During Kosher compliance verification, we learned the importance of strictly segregating utensils and scheduling dedicated cleaning cycles. Close coordination with local inspectors accelerated the sign-off process and avoided costly delays.
For long-term operation in Mexico City’s humid, mild climate, I recommend quarterly checks on de-oiling and cooling systems to prevent condensation and maintain crispness, especially during the rainy season. The local water supply’s high mineral content also warrants regular descaling of blanchers and fryers.
