Client Background and Market Context
The client, a mid-sized family-owned snack manufacturer based in Lahore, Pakistan, has been producing fried snacks for over a decade. Facing rising demand and increasing competition, the company sought to upgrade from manual and semi-automatic equipment to a fully-automatic line to enhance consistency, reduce labor dependency, and ensure Halal and PSQCA compliance for market expansion.
According to Statista, the Pakistani savory snacks market exceeded USD 1.2 billion in 2023, with a CAGR of 8.7 percent. Leading competitors include Lays, Kurleez, and Super Crisp, all of whom have expanded automated capacity in recent years. The timing was driven by post-pandemic consumption recovery and the need to meet strict Halal and food safety standards, providing a strategic window for investment in high-throughput production.
Pain Points and Procurement Requirements
Prior to this project, the client struggled with inconsistent product quality, high oil absorption, labor shortages, and an inability to meet evolving Halal and food safety standards. These issues limited both output and market access, threatening long-term growth.
- High Line Capacity: System must reliably deliver at least 500 kg per h compound chips output without bottlenecks.
- Low Oil Absorption Rate: Finished chips must maintain oil uptake below 30 percent to meet cost and quality benchmarks.
- Energy Efficiency: Equipment must minimize electricity and gas consumption to control per kg operating cost.
- Halal Compliance: All food contact surfaces and additives must be certified Halal and traceable.
- Fast After-Sales Support: Local technical issues must be resolved within 24 hours to avoid costly downtime.
Engineering Solution and Process Description
The process begins with raw potato intake, where Kufri Chipsona-1 and Lady Rosetta varieties are received and inspected for size grade A uniformity. Potatoes are loaded onto the ZX-PT-800 Peeling Machine utilizing abrasive rollers, which efficiently remove skins with minimal starch loss, critical for 21 to 24 percent starch content typical in Pakistani crops.
Next, sorting is performed via a Vibratory Grading Conveyor to eliminate undersized or defective tubers, ensuring only optimal potatoes proceed. Rebanar is accomplished with the JQ-2000 Rotary Slicer, set for 1.5 mm thickness for compound chips, a parameter chosen to balance crispness with oil absorption.
El washing stage employs a Multi-Stage Bubble Washer to remove surface starch and reduce microbial load. Blanqueamiento follows in the BL-500 Continuous Blancher at 80 deg C for 90 seconds, optimizing color and reducing acrylamide formation, especially important for high-starch local potatoes.
De-watering is achieved with a Centrifugal Dewaterer to minimize surface moisture, directly affecting oil absorption rate and downstream frying efficiency. Fritura uses the FRY-1200 Continuous Fryer with precise PID temperature control at 180 deg C, ensuring even cooking and minimizing oil degradation.
De-oiling is handled by the Vortex De-oiler, which removes excess oil and achieves a finished product oil absorption of 28.5 percent. Cooling is managed by a Crossflow Cooling Tunnel to stabilize texture before seasoning.
Seasoning is applied in a Drum Coater with adjustable dosing for flavor uniformity. Metal detection ensures food safety prior to automatic packing via the PK-400 Vertical Form Fill Seal Machine, which delivers up to 40 packs per minute, supporting high-volume retail distribution.

On-Site Installation and Commissioning Story
The equipment was shipped from Qingdao, China to Karachi Port via ocean freight, with a transit time of 18 days. Upon arrival, customs clearance proceeded smoothly thanks to pre-arranged documentation under PSQCA guidelines. The machinery was unloaded and trucked to the Lahore facility, ready for installation.
During installation week, the major technical challenge was voltage stabilization. Fluctuations in the local grid (220V, 50Hz) risked PLC errors and fryer temperature drift. Our engineering team installed an industrial-grade AVR and surge protection system, ensuring consistent power supply. Additionally, humidity levels averaging 65 percent in Lahore required calibration of de-oiling and cooling steps to maintain product crispness.
The trial production phase began under ambient temperatures of 27 deg C. The first batch achieved the target oil absorption rate of 28.5 percent, with all critical control points passing Halal and PSQCA audits. The client was impressed with the uniformity and throughput, noting a throughput stability of ±2 percent across three consecutive shifts.
Compliance and Certification Pathway
The entire line was engineered to comply with PSQCA food safety standards (Pakistan Standard PS: 3733-2019), Halal requirements as per Pakistan Halal Authority, and CE machine safety directives for export. All food contact surfaces, additives, and lubricants were certified Halal, and the process flows were validated for traceability and allergen segregation.
Key equipment features supporting certification included acero inoxidable 304 contact zones for HACCP and Halal compliance, color-coded segregated production zones, and a CE-marked Siemens PLC system. The seasoning line was equipped with a dedicated Halal ingredient hopper to ensure no cross-contamination, while all electrical panels met IEC 60204-1 safety standards.
Engineer Field Notes
During commissioning, we carefully adjusted the blanqueamiento and fritura parameters to accommodate the Kufri Chipsona-1 and Lady Rosetta potatoes. Their 21-24 percent starch content required slightly lower blanching temperatures and extended de-watering to prevent surface stickiness and ensure crispness in the compound chips.
A key lesson came during Halal compliance verification. We discovered that even minor non-food grade lubricants in the conveyor drive presented a risk. We replaced all lubricants with Halal-certified food-grade alternatives and trained the client’s maintenance staff on strict documentation and traceability.
For long-term operation in Lahore’s tropical monsoon climate, we recommend regular inspection of the de-oiling and cooling systems, especially during the high humidity months. Keeping the cooling tunnel filters clean and monitoring ambient humidity is critical to maintaining chip crispness and shelf life.
