Client Background and Market Context
The client is a mid-sized snack manufacturer based in Bangkok, Thailand, operating multiple fried snack lines and seeking to diversify into premium potato chips. Their procurement motivation centered on meeting rising demand for locally produced, certified snacks with reliable throughput and strict food safety compliance. This investment was also driven by the need to respond to evolving consumer preferences for quality and traceability in the Thai market.
According to Statista, the Thai savory snack market reached USD 1.8 billion in 2023 with a 5.1 percent CAGR. Leading competitors include Lay’s Thailand, Hanami, and Greenday. The timing of this project aligns with a market shift toward higher-value, certified products and the ongoing expansion of the urban middle class in Thailand.
Pain Points and Procurement Requirements
Prior to procurement, the client faced bottlenecks in consistent chip quality, high oil absorption rates, and the inability to meet both Halal and FDA Thailand certification requirements on legacy equipment, resulting in lost contracts with major retailers and food service chains.
- Consistent 300 kg per h Throughput: Line must deliver stable output with minimal downtime and tight weight variance.
- Oil Absorption Rate Control: Finished chips must not exceed 32 percent oil absorption to meet health and labeling requirements.
- Energy Efficiency: System must optimize electricity and gas use, targeting below 0.10 USD per kWh and 0.40 USD/m³.
- Halal and FDA Compliance: All processes and materials must be certified for Halal and pass FDA Thailand inspection.
- Rapid After-sales Response: Technical support must guarantee <24 hour remote diagnostics and local spare parts availability.
Engineering Solution and Process Description
The production process begins with raw potato intake using an automated hopper elevator designed for the Atlantic variety, which typically has a 20 percent starch content. The elevator feeds into a rotary drum washer (ASM-W350) that removes soil and debris, ensuring minimal surface damage for size grade M-L tubers.
Next, a steam peeler (ASM-SP300) rapidly removes skin with minimal yield loss, followed by an optical sorter to reject substandard potatoes and foreign matter. The line uses a centrifugal slicer (ASM-CS350) set to 1.4 mm thickness, optimized for Atlantic’s texture and moisture profile.
The multi-stage washing system features a three-tank configuration with continuous water recirculation and de-starching modules, which is crucial for reducing free starch and minimizing stickiness during frying.
Blanching is performed in a continuous flow blancher (ASM-BL300) at 75 deg C for 3 minutes, controlling enzyme activity and color stability. A vibration de-watering unit ensures excess surface water is removed prior to frying, improving oil uptake control.
The core of the line is the continuous fryer (ASM-FR300), utilizing a three-zone oil temperature control system (165-175 deg C) to ensure uniform cooking. The fryer is equipped with an integrated oil filtration system to prolong oil life and maintain product quality, especially important for high humidity conditions in Bangkok.
Post-frying, the chips pass through a centrifugal de-oiler and then a cooling conveyor. The seasoning drum (ASM-SD100) provides even flavor distribution. Finished chips undergo metal detection (ASM-MD2) before entering the automatic packing machine (ASM-PK150), which supports pillow and gusset bag formats at up to 30 packs per minute.

On-Site Installation and Commissioning Story
The complete production line was shipped from Qingdao, China, to Laem Chabang Port near Bangkok, arriving after 13 days at sea. After efficient customs clearance in Thailand, the equipment was unloaded and transported to the client’s facility. All machinery arrived intact and ahead of schedule, minimizing local storage time and risk.
Installation spanned seven days, with the main challenge being voltage stabilization due to fluctuations in the plant’s grid supply. Our engineering team installed an automatic voltage regulator to protect the PLC and sensitive control panels. Additionally, local humidity of 75 percent required extra attention to dehumidification in the seasoning and packing zones to ensure product crispness.
During trial production, the first batch was processed at an ambient temperature of 31 deg C and relative humidity of 78 percent. The line achieved a stable output of 302 kg per h with oil absorption averaging 31.7 percent. The client was impressed by the uniform chip color and crispness, noting the absence of common surface blisters.
Compliance and Certification Pathway
The production line was engineered to meet FDA Thailand requirements (Ministry of Public Health Notification No. 420) and Halal certification standards set by the Central Islamic Council of Thailand. All processes, from raw material handling to final packing, were documented for traceability and audit readiness, ensuring smooth certification and market entry.
Key equipment features include stainless steel 304 contact surfaces for hygienic compliance, segregated production zones to prevent cross-contamination, and CE-marked PLC controls. Halal compliance was supported by exclusive use of approved lubricants and cleaning agents, with supplier declarations filed for all contact materials.
Engineer Field Notes
During commissioning, we quickly learned the Atlantic potatoes sourced locally in Thailand had a slightly higher median size and a starch content of about 20 percent. This required us to fine-tune the blanching time and frying temperature to prevent excessive browning and optimize the oil absorption rate. Adjusting the slicer thickness to 1.4 mm proved ideal for balancing crispness and throughput.
A critical lesson emerged during the Halal compliance audit: all lubricants and cleaning agents must have valid Halal certification. We worked closely with local suppliers to replace two imported products, ensuring the line passed the first inspection by the Central Islamic Council.
For long-term operation in the Bangkok tropical humid climate, I recommend regular inspection of the dehumidification units and periodic oil filtration system maintenance. This greatly reduces the risk of product softening and extends the fryer oil life, especially during the rainy season when humidity can exceed 80 percent.
