Client Background and Market Context
The client is a mid-sized snack manufacturer in Dhaka, Bangladesh with a growing presence in the urban packaged foods market. Faced with escalating demand and increasing regulatory scrutiny, the company sought to modernize its potato chips production to ensure consistent quality, Halal compliance, and scalable throughput. Their procurement motivation was driven by the need to replace outdated batch fryers and manual packing with a semi-automatic solution that would assure both food safety and operational efficiency.
According to IMARC Group, the Bangladesh snacks market was valued at USD 1.2 billion in 2023, with a projected CAGR of 8.2 percent through 2028. The market is highly competitive, with leading brands such as Bombay Sweets, Pran, and Meridian Foods dominating shelf space. The client’s timing aligned with a surge in urban snack demand and a policy push for locally certified, Halal-compliant foods.
Pain Points and Procurement Requirements
The customer previously struggled with inconsistent product quality, high oil absorption, and the inability to meet Halal and FSSAI standards. Manual processes resulted in variable throughput and frequent product losses, limiting their ability to compete with larger brands.
- Consistent Capacity: The line must maintain a steady 150 kg per h throughput to meet order volumes without overloading staff.
- Low Oil Absorption Rate: Finished chips should not exceed 35 percent oil content to ensure crispness and health standards.
- Energy Efficiency: The solution must optimize electricity and gas use to reduce per-batch operating costs.
- Halal Compliance: All contact surfaces and process flows must meet Halal guidelines for the Bangladeshi market.
- Rapid After-Sales Support: Critical spare parts and technical support must be available within 48 hours to minimize downtime.
Engineering Solution and Process Description
The semi-automatic potato chips line is designed for Lady Rosetta and Kufri Chipsona-1 potatoes, which are favored in Bangladesh for their 22 percent starch content and uniform size. The process begins with raw potato intake and peeling using the ASM-P150 Abrasive Peeler, calibrated for minimal skin loss and high throughput. This is critical for maximizing yield from medium-sized tubers (average 55mm diameter).
Next, sorting and slicing is performed with the ASM-SL2 Rotary Slicer, featuring adjustable blade thickness (1.6mm to 2.0mm) to suit the high-starch profile of Lady Rosetta. This ensures uniform chip size and optimal surface area for subsequent blanching and frying.
Washing and бланширование occur in the ASM-BL1 Continuous Blancher, which maintains water temperature at 70 deg C. This step removes excess starch, preventing stickiness and improving color retention. The blancher’s overflow design and controlled dwell time (90 seconds) are matched to the local tuber chemistry.
De-watering is achieved via the ASM-DW2 Centrifugal Dewaterer, reducing surface moisture to below 4 percent before frying. This step is essential for low oil absorption and crisp texture, especially in humid climates.
The жарка stage utilizes the ASM-FR150 Batch Fryer with a gas-fired heating system. Oil temperature is precisely controlled at 180 deg C, with a residence time of 150 seconds. The fryer’s oil circulation and filtration system maintain a consistent oil quality, directly impacting product flavor and shelf life.
Post-frying, de-oiling is handled by the ASM-DO1 De-oiler, which spins chips at 900 rpm for 20 seconds, bringing residual oil down to target levels. Cooling and seasoning are performed in the ASM-CL1 Cooling Conveyor and ASM-SN1 Seasoner, ensuring even flavor distribution and rapid temperature drop for packaging.
Finally, metal detection (via ASM-MD1) and packing (via ASM-PK1 Semi-Auto Packager) guarantee food safety and compliance with FSSAI traceability standards. The semi-automatic workflow balances labor input with automation for cost-effective, certifiable production.

On-Site Installation and Commissioning Story
The equipment was shipped from Qingdao to Chittagong Port in 19 days, followed by customs clearance and overland transport to Dhaka. Despite monsoon season delays, all modules were unloaded and staged at the client’s facility within 26 days of vessel departure, aided by streamlined documentation and local agent support.
Installation was completed in one week. A key technical challenge arose with voltage stabilization, as local grid fluctuations risked PLC faults. Our engineers deployed an industrial-grade AVR (Automatic Voltage Regulator) to maintain stable 220V, 50Hz supply, preventing downtime. The team also implemented additional humidity control around the seasoning and packing area to address the city’s tropical monsoon climate.
Trial production coincided with typical June weather in Dhaka: 27 deg C average temperature and 65 percent humidity. The first batch achieved 149.2 kg/h throughput and 33 percent oil absorption, passing both FSSAI and Halal audits on the first attempt. The customer expressed satisfaction with product crispness and operational simplicity.
Compliance and Certification Pathway
The line was designed to meet FSSAI (Food Safety and Standards Authority of India, as adopted in Bangladesh) and Halal standards, with equipment and process flows engineered for full traceability and religious compliance. All critical control points were documented according to FSSAI 2011 and OIC/SMIIC 1:2019 Halal codes, ensuring audit readiness and export potential.
Equipment features supporting compliance include нержавеющая сталь 304 contact surfaces for HACCP and Halal hygiene, segregated seasoning and packing areas to prevent cross-contamination, and CE-marked PLC control panels for safety certification. All lubricants and process aids are Halal-certified, and the process flow was validated by third-party auditors prior to commissioning.
Engineer Field Notes
During commissioning, we adapted slicing and frying parameters for local Lady Rosetta potatoes, which in Dhaka typically present 22 percent starch and medium size. Adjusting blade thickness to 1.8mm and blanching time to 90 seconds minimized stickiness and ensured even golden coloration, critical for market acceptance.
A key lesson emerged in verifying Halal compliance: every lubricant, cleaning agent, and packaging input required documentation and sourcing from approved suppliers. This step demanded close client collaboration and was central to passing the initial Halal audit.
For long-term operation in tropical monsoon conditions, I recommend periodic checks on dewatering and seasoning modules. High ambient humidity can lead to product softening if cooling airflow drops or if packing is delayed. Regular filter changes and strict process discipline are vital for consistent crispness.
