Client Background and Market Context
The client, a mid-sized snack manufacturer based in Monterrey, Mexico, operates several brands in the regional savory snacks market. With a vision to diversify its product portfolio, the company targeted the growing demand for healthier, alternative chips. Their procurement was motivated by the need to automate production, improve product consistency, and meet Kosher standards for export and domestic health-focused retail.
According to Statista, the Mexican savory snacks market was valued at USD 3.9 billion in 2023, with a robust 5.3 percent CAGR projected through 2028. Major competitors include Sabritas, Barcel, and Churrumais. The client’s entry timing was driven by rising consumer preference for sweet potato-based snacks and retailer demand for certified, traceable, and innovative products.
Pain Points and Procurement Requirements
Prior to this project, the client struggled with inconsistent chip quality, high oil content, and manual production bottlenecks that limited throughput and regulatory compliance. The lack of process automation also made it difficult to ensure Kosher standards and traceability for export partners.
- High Capacity: Required minimum 500 kg/h throughput to supply national retailers and meet growing demand.
- Low Oil Absorption: Targeted final product oil content below 25 percent for healthier positioning.
- Energy Efficiency: Needed integrated heat recovery and smart controls to minimize electricity and gas costs.
- Kosher Compliance: All contact surfaces and process flows had to meet Kosher requirements for certification.
- Fast After-Sales Support: Required guaranteed 24-hour engineer response for any critical downtime.
Engineering Solution and Process Description
The production process begins with raw sweet potato intake, utilizing a belt-type hopper elevator designed for handling the regional Innovator variety with 21 percent starch content. This ensures gentle transfer and minimal bruising, critical for chips color and texture.
Next, peeling is performed by a rotary abrasive peeler (model ASP-800), calibrated for medium-sized tubers (130-180g average). This step achieves over 98 percent peel removal with minimal flesh loss, key for yield.
Sorting and slicing uses a multi-channel optical sorter and a disc slicer (model SCS-600), ensuring uniform 1.6 mm slice thickness for even frying. The sorter removes defects and foreign objects, critical for food safety and NOM-251-SSA1-2009 compliance.
Washing and blanching are handled by a vortex washer and a continuous blancher (model BLQ-500), tuned to 85 deg C for 90 seconds to reduce enzymatic browning and surface starch, optimizing chip color.
De-watering is achieved via a centrifugal de-waterer (model DWT-500) to lower surface moisture, which directly impacts oil absorption rate during frying.
menggoreng occurs in a continuous fryer (model FRY-1000), with smart PLC control of frying temperature (165-175 deg C) and oil circulation. Integrated heat recovery reduces gas consumption by 12 percent.
De-oiling follows using a vibration de-oiler (model DEO-600), which achieves final oil content below 25 percent, critical for product appeal and shelf life.
Cooling and seasoning are managed with a spiral cooler and a drum-type flavoring mixer, ensuring even temperature reduction and seasoning coverage.
Metal detection and automated packing (model PKG-400) complete the process, ensuring food safety and high-speed bagging at up to 48 bags per minute.

On-Site Installation and Commissioning Story
The complete production line was shipped from Qingdao, China to Altamira Port, Mexico over 27 days via ocean freight. Upon arrival, customs clearance was completed within five working days, reflecting the robust import protocols in Mexico. The equipment was safely unloaded and transported to the client’s facility in Monterrey, with all components arriving intact and on schedule.
Installation took place during March, with average temperatures around 22 deg C and 60 percent humidity. A specific technical challenge arose with voltage stabilization, as the local grid experienced fluctuations. Our engineering team installed a dedicated industrial voltage regulator to ensure consistent 220V, 60Hz supply, safeguarding sensitive PLC and IoT modules from power surges.
During the trial production phase, the first batch of sweet potato chips achieved a stable oil absorption rate of 24 percent and throughput of 505 kg/h. The customer was especially impressed with the crispness retention, despite the humid spring weather. The line passed all acceptance tests on the first attempt.
Compliance and Certification Pathway
The production line was engineered to fully comply with NOM-251-SSA1-2009 food safety standards, which govern hygiene and process control in Mexican food manufacturing. Kosher certification was achieved by ensuring all contact surfaces and process flows met rabbinical supervision requirements, with full segregation of non-Kosher materials. Equipment design also aligns with Codex Alimentarius and HACCP principles.
Key compliance features include keluli tahan karat 304 food-contact surfaces, CE-marked PLC controls, and traceability modules for batch records. The facility is zoned to segregate raw and finished product flows, supporting both Kosher and NOM-251 certification. All critical control points are monitored and logged for regulatory audit readiness.
Engineer Field Notes
Adapting our process to the local Innovator sweet potato variety with its 21 percent starch content and medium size (130-180g) required fine-tuning the slicing and frying modules. We adjusted slicer blade angle and set the blancher at 85 deg C for optimal texture, resulting in consistently thin, crispy chips.
During Kosher compliance verification, our team learned the importance of strict material segregation. We implemented color-coded cleaning tools and dedicated oil filtration units to prevent any cross-contamination, which was critical for rabbinical approval and future audits.
For long-term operation in Monterrey’s semi-arid climate, I recommend quarterly calibration of the humidity sensors and routine checks on the spiral cooler. Stable cooling is vital for crispness retention, especially during the humid summer months.
