Client Background and Market Context
The client is a mid-sized snack manufacturer based in Lagos, Nigeria, operating in the FMCG sector with a focus on traditional and innovative snack foods. Facing rising demand for premium banana chips in both retail and export channels, the company sought to modernize its production with higher automation and strict food safety compliance. Their procurement motivation was to capture the growing urban market and meet international buyer requirements.
According to Statista, the Nigerian snack market reached USD 1.2 billion in 2023, with a CAGR of 6.4 percent driven by urbanization and changing dietary habits. Key competitors include Chipsy, Leventis Foods, and UAC Foods. With market demand outpacing supply and regulatory scrutiny increasing, the timing for scaling up with a certified, high-capacity line was optimal.
Pain Points and Procurement Requirements
Prior to this project, the client struggled with inconsistent chip quality, excessive oil content, and frequent downtime due to semi-manual batch processes. Their main pain point was the inability to produce at scale while maintaining oil absorption and crispness within specification, especially during humid rainy seasons.
- High Throughput: The line must reliably process at least 500 kg per h of raw banana slices without bottlenecks.
- Low Oil Absorption: Finished chips must maintain oil content below 25 percent to meet premium quality standards.
- Energy Efficiency: Total electricity and gas usage must not exceed 0.12 kWh and 0.09 m3 per kg output, respectively.
- Halal Compliance: All materials and processes must adhere to Halal requirements for both local and export markets.
- Rapid After-sales Support: On-site or remote technical support must be available within 12 hours to minimize downtime.
Engineering Solution and Process Description
Le fully-automatic banana chips line begins with raw banana intake via a stainless steel belt conveyor designed for smooth handling and minimal bruising of the Musa spp. variety, which has a typical starch content of 20 percent. Initial sorting is achieved with a roller grader that removes undersized or overripe fruit, ensuring only uniform, mature bananas proceed.
Next, the peeling station employs a rotary drum peeler with adjustable abrasion to accommodate the medium size grade typical in West Africa. This is followed by automatic slicing using a rotary slicer (model ASM-SL500) with a precision blade set at 1.8 mm thickness, critical for even frying and minimizing breakage.
Slices are transferred to a bubble washing machine for thorough removal of surface starch and latex, reducing stickiness and improving downstream flow. After washing, slices pass through a blanching unit set at 90 deg C for 60 seconds to deactivate enzymes and enhance color retention, which is especially important given the high humidity and rapid browning risk.
Post-blanching, a centrifugal de-watering machine (model ASM-DW400) reduces surface moisture to below 5 percent, optimizing frying efficiency and lowering oil uptake. The continuous fryer (model ASM-FR600) operates at 170 deg C with a residence time of 110 seconds, using palm oil and equipped with a three-zone temperature PID controller for precise heat distribution.
Fried chips are immediately transferred to a vibration de-oiling conveyor, which ensures oil absorption stays below 24 percent, even in Lagos’ 55 percent average humidity. After de-oiling, chips enter a cooling tunnel before moving to a seasoning drum with atomized flavor dosing for consistent coating.
The final stages include metal detection (sensitivity 0.8 mm Fe) and automatic packing using a vertical form-fill-seal (VFFS) machine, which delivers up to 40 bags per minute in nitrogen-flushed pouches for maximum shelf life and crispness.

On-Site Installation and Commissioning Story
The production line was shipped from Qingdao, China to Lagos Port over a transit period of 36 days. After customs clearance and inspection by Nigerian authorities, unloading was completed in two days with all equipment checked for transit damage. The team coordinated local logistics to ensure prompt delivery to the client’s facility.
Installation week was marked by a challenge in voltage stabilization due to grid fluctuations in Lagos. The engineering team implemented an automatic voltage regulator and surge protection system to ensure consistent 230V 50Hz supply. Additionally, the persistent 55 percent humidity and 24 deg C ambient temperature required adjustments to the de-oiling and cooling stages to maintain chip crispness.
During the trial production phase, the first batch of banana chips achieved a measured oil absorption rate of 23.5 percent and a throughput of 507 kg per h. The client was impressed by the uniformity and texture of the chips, noting the system’s stability even under Lagos’ variable climate.
Compliance and Certification Pathway
The line was custom-engineered to meet NAFDAC food safety requirements and Halal certification for the Nigerian market. All process steps and documentation aligned with Codex Alimentarius standards and NAFDAC food processing codes, while the use of Halal-certified lubricants and separation of non-conforming material zones ensured full religious compliance.
Equipment features included SS304 contact surfaces for hygienic design and easy washdown, segregated production zones for allergen and Halal control, and CE-marked PLCs for export readiness. The continuous fryer and conveyor systems were validated for HACCP critical control points, supporting both local and international product traceability.
Engineer Field Notes
During commissioning, we observed that the local banana variety had a slightly higher moisture and lower starch content compared to Asian cultivars. We fine-tuned the blanching time and de-watering speed to ensure optimal crispness and prevent excessive oil uptake, which was essential for consistent chip texture.
One critical lesson was the importance of Halal compliance documentation. The local auditor required detailed segregation records for all materials and process zones. Our advance preparation with color-coded bins and digital traceability made the audit process smooth and transparent.
For long-term operation in Lagos’ humid, tropical climate, we recommend regular checks of the de-oiling and cooling systems. Humidity can quickly affect chip shelf life and texture, so maintaining airflow and equipment hygiene is essential for quality assurance year-round.
