Client Background and Market Context
The client, a mid-sized FMCG manufacturer based in Karachi, Pakistan, operates multiple snack brands catering to both urban and export markets. Their procurement motivation was to expand halal-certified potato snack output and address rising demand from retail and HORECA channels. With a focus on food safety and process automation, the client sought a robust, scalable solution to replace legacy semi-automatic lines and meet strict Halal and PSQCA requirements.
According to Statista, the Pakistan snack market was valued at USD 1.4 billion in 2023, with a projected CAGR of 7.9 percent over the next five years. Major competitors include Lay’s, Kolson, and Super Crisp. The client’s investment timing was driven by growing urbanization, rising disposable income, and evolving consumer preferences for certified snacks, making Karachi a strategic hub for industrial snack manufacturing.
Pain Points and Procurement Requirements
Before upgrading, the client struggled with inconsistent product quality, batch-to-batch oil absorption variance, and lengthy downtime due to manual intervention and lack of compliance traceability. These challenges limited their ability to scale output, meet Halal standards, and compete effectively against leading brands.
- Stable High Capacity: The line must sustain at least 500 kg/h output with minimal deviation in throughput during peak demand periods.
- Controlled Oil Absorption Rate: Achieve and maintain oil absorption below 24 percent to ensure crispness and regulatory compliance.
- Energy Efficiency: Total power consumption per ton must be optimized to reduce cost per kg and environmental footprint.
- Halal Compliance: All contact materials, process flows, and additives must strictly adhere to Halal guidelines for local and export markets.
- Rapid After-Sales Support: Guarantee technical response time of less than 24 hours for critical troubleshooting and parts replacement.
Engineering Solution and Process Description
The process begins with raw potato intake, where washed Kufri Chipsona-1 tubers (average size grade 55-70 mm) are manually loaded onto a vibratory feed conveyor. This ensures even flow into the brush roller peeler (Model: ASP-800), which is calibrated for the 21-24 percent starch content typical of local supply, balancing thoroughness with minimal yield loss.
Peeled potatoes move to the optical sorter (Model: ASO-400) that detects and removes green, damaged, or undersized pieces. The slicer (Model: ASS-500) uses hardened stainless steel blades set at 1.6 mm thickness, optimizing slice integrity for high-starch varieties and minimizing breakage.
Slices enter a vortex washing system (Model: ASW-600) with continuous water circulation to remove surface starch and prevent clumping. The blancher (Model: ASB-500) operates at 85 deg C for 90 seconds, ensuring enzyme deactivation and color retention, calibrated for high ambient humidity and starch load.
After blanching, slices are transferred to a centrifugal de-watering unit (Model: ASD-350) to reduce surface moisture, which is critical for uniform frying and minimizing oil uptake. The continuous fryer (Model: ASF-1500) uses a three-zone temperature profile (165-175 deg C) to achieve an oil absorption rate below 23 percent, with auto oil filtration to extend oil life.
Post-frying, a de-oiling conveyor (Model: ASO-800) removes excess oil before slices are cooled in a vibratory cooling tunnel (Model: ASC-400). Seasoning is applied via a drum applicator (Model: ASSN-300) with PLC-controlled dosing for consistency. Final product passes through a metal detector (Model: ASM-200) before entering the automatic packing machine (Model: ASPK-250), which supports both pillow and gusset bag formats.

On-Site Installation and Commissioning Story
The equipment shipped from Qingdao port to Karachi Port in 19 days, followed by three days of customs clearance in Pakistan. Upon arrival, the containers were unloaded and staged for assembly in the client’s new production facility, with all modules checked for transit damage and compliance with import documentation.
Installation commenced during late spring, with tropical monsoon climate, an average temperature of 27 deg C, and relative humidity at 65 percent. A technical challenge arose with the voltage stabilizer, as local grid fluctuations affected PLC startup. The engineer team reconfigured the transformer taps and installed an additional surge protector, ensuring stable 220V 50Hz supply for sensitive controls. Water treatment was also optimized to prevent scaling in blancher heat exchangers.
During the trial production phase, the first batch achieved a steady 500 kg/h output with uniform crispness and a measured oil absorption rate of 22.8 percent. The customer noted improved product color and texture, with minimal breakage despite the high ambient humidity. The commissioning team documented all parameters and provided operator training for ongoing quality control.
Compliance and Certification Pathway
The line was engineered to comply with PSQCA (Pakistan Standards & Quality Control Authority) and Halal requirements, referencing PS: 3733-2019 for snack foods and OIC/SMIIC 1:2019 for Halal production. All process steps and additives were validated for religious compliance, with traceability established through batch coding and segregated ingredient storage.
Equipment featured zanglamaydigan po'lat 304 contact surfaces for HACCP and Halal compatibility, while the production line layout included designated zones to prevent cross-contamination. The PLC control panel was CE-marked and fitted with audit logs for traceability. All lubricants and cleaning agents were Halal-certified, and operator workflows were documented for certification audits.
Engineer Field Notes
During commissioning, the unique characteristics of Kufri Chipsona-1 potatoes—especially the 21-24 percent starch content and 55-70 mm size grade—required precise adjustment of the slicing thickness and blanching time. We ran several test batches to find the optimal settings that balanced crispness with minimal oil uptake, ultimately locking in a 1.6 mm slice and a 90-second blanch.
A critical lesson emerged during Halal compliance verification: even minor cross-contact with non-certified cleaning agents can jeopardize certification. We instituted strict color-coded tool policies and double-checked all supplier documentation before audit, which saved significant time and avoided rework.
For long-term performance in Karachi’s tropical monsoon climate, I recommend regular inspection of electrical panels for condensation and maintaining a dehumidified storage area for seasoning powders. These preventive steps will help sustain quality and reduce unexpected downtime during the rainy season.
