Client Background and Market Context
The client, a mid-sized snack foods company based in Pune, India, operates several regional brands focused on traditional and westernized potato snacks. Facing rising demand and tightening quality standards, the company sought to upgrade from batch frying to a fully-automatic continuous line to boost output and guarantee product consistency. Their procurement motivation centered on meeting new FSSAI guidelines and expanding into modern retail channels.
According to IMARC Group, India’s savory snacks market exceeded USD 8.6 billion in 2023, with a projected 10.5 percent CAGR through 2028. Major competitors include Haldiram’s, Bikaji Foods, and Balaji Wafers. With urbanization and organized retail accelerating, the timing was ideal for the client to invest in high-throughput, compliant production capacity.
Pain Points and Procurement Requirements
Before the upgrade, the client struggled with frequent downtime, inconsistent chip color, and high oil content due to manual batch processing. These issues limited their ability to scale and meet retailer requirements for shelf life and product uniformity.
- High Throughput: The line must process at least 800 kg/h raw potatoes with minimal fluctuation.
- Oil Absorption Rate: Finished chips must consistently achieve less than 30 percent oil absorption.
- Energy Efficiency: Total power and gas usage must be at least 10 percent lower than previous batch systems.
- Vegetarian Compliance: All equipment and process flow must meet Vegetarian standards for the Indian market.
- Rapid After-sales Support: On-site engineering response required within 24 hours of any critical failure.
Engineering Solution and Process Description
The process begins with raw potato intake, where Kufri Chipsona-1 tubers (average size grade 45-55 mm, starch content 22 percent) are loaded onto an elevating conveyor feeding the automatic destoner and washer (Model ASM-W600). This system removes soil and surface debris, critical for minimizing starch buildup and ensuring clean slicing.
Cleaned potatoes are transferred to the peeling machine (Model ASM-P500), which uses abrasive rollers set for thin-skin removal, preserving yield for high-starch Indian varieties. Post-peeling, a sorting conveyor allows manual inspection and removal of defective tubers.
Next, potatoes enter the slicing machine (Model ASM-S800) fitted with adjustable stainless steel blades for 1.5 mm slice thickness. This ensures rapid, uniform slicing essential for even blanching and frying, especially given the high starch content of local varieties.
Slices are washed and de-starched in a vortex washer, then conveyed to the blanching unit (Model ASM-BL600) where slices are blanched at 80 deg C for 2.5 minutes to deactivate enzymes and prevent excess browning.
Blanched slices pass through a centrifugal de-watering machine (Model ASM-DW400), minimizing surface moisture and optimizing oil pick-up in the subsequent continuous fryer (Model ASM-FR1000). The fryer operates at 175 deg C with precise temperature control, ensuring crispness and controlled oil absorption.
Post-frying, chips enter the de-oiling centrifuge, reducing surface oil, then move via a cooling conveyor to the seasoning drum (Model ASM-SN500) where uniform flavoring is applied. A metal detector ensures food safety before final packaging in the vertical form-fill-seal (VFFS) machine, which delivers up to 60 bags per minute with nitrogen flushing for shelf life extension.

On-Site Installation and Commissioning Story
The equipment was shipped from Qingdao port, China, to Mumbai port, India, arriving after 18 days at sea. Upon clearing customs, the containers were trucked to Pune, where unloading was completed with local crane support. All equipment arrived intact, and pre-shipment labeling facilitated rapid inventory checks.
Installation commenced during the tropical monsoon season, with ambient temperatures averaging 27 deg C and 65 percent humidity. A key technical challenge was maintaining voltage stabilization due to grid fluctuations. Our engineering team installed an automatic voltage regulator and performed line harmonization, ensuring all motors and PLCs operated within tolerance.
The trial production phase began after 12 days of assembly. The first batch achieved 790 kg/h throughput with 29 percent oil absorption, exceeding the client’s expectations. The customer praised the consistent chip color and crispness, noting that the line performed reliably despite high humidity and temperature swings.
Compliance and Certification Pathway
The line was designed and documented to comply with FSSAI (Food Safety and Standards Authority of India) regulations and ISO 22000 food safety management. All process steps and materials were validated to meet Vegetarian standards, a cultural imperative for mass-market Indian snacks. Reference standards included FSSAI Schedule IV and Codex Alimentarius CAC/RCP 1-1969 for hygiene.
Equipment was fabricated with aço inoxidável 304 food contact surfaces, fully welded seams, and segregated cleaning zones. The PLC control panel was CE-marked and featured password protection for process traceability. Seasoning and oil handling zones were isolated to prevent cross-contamination, supporting both FSSAI and Vegetarian requirements.
Engineer Field Notes
Adapting the line to Kufri Chipsona-1 potatoes with 22 percent starch and a 45-55 mm average size required fine-tuning of blanching and frying parameters. We reduced blanch time to 2.5 minutes and set the fryer at 175 deg C to control browning and optimize crispness, compensating for the high starch content typical of Indian varieties.
During Vegetarian compliance verification, we learned that even minor cross-contact with non-vegetarian ingredients in shared seasoning lines would disqualify the product for major retailers. We implemented color-coded utensils and dedicated cleaning schedules, a lesson that now informs all future Indian projects.
For sustained performance in the tropical monsoon climate, I recommend regular inspection of electrical cabinets for condensation and maintaining silica gel packs during the rainy season. This prevents humidity-induced faults and keeps the PLCs running smoothly.
