Client Background and Market Context
The client is a mid-sized snack manufacturer based in Hanoi, Vietnam, operating for over 10 years in the northern Vietnamese snack sector. Their motivation for procurement stemmed from capacity constraints with legacy semi-automatic lines and the need to meet stricter food safety and Halal requirements to access new distribution channels. The company sought a reliable, high-throughput solution to compete with larger national brands and expand into modern trade.
According to Statista, the Vietnamese snack market reached USD 1.95 billion in 2023 with a CAGR of 8.6 percent. Key competitors include Oishi Vietnam, Orion Food Vina, and Hai Ha Confectionery. Timing was driven by the rapid growth of urban retail and rising demand for certified, high-quality snacks in Vietnam.
Pain Points and Procurement Requirements
Prior to upgrading, the client faced chronic production bottlenecks, inconsistent oil absorption rates, and costly manual interventions. Meeting Halal and FDA Vietnam requirements was a major barrier to entering new retail channels, while escalating labor and energy costs reduced competitiveness.
- High Capacity: The line must deliver stable output at 1,000 kg per h to meet growing demand and reduce overtime.
- Low Oil Absorption Rate: Finished chips must consistently achieve below 27 percent oil absorption for better texture and shelf life.
- Energy Efficiency: The solution should minimize electricity and gas consumption per kg produced.
- Halal Compliance: All contact surfaces and processes must be verifiably Halal for certification.
- Rapid After-Sales Response: Local support must respond within 24 hours to minimize downtime.
Engineering Solution and Process Description
The process begins with potato intake and raw material handling, where bulk Atlantic potatoes (average 19 to 22 percent starch) are unloaded into the ZYX-1000 Hopper Elevator. This model ensures gentle transfer to minimize bruising, which is critical for preserving chip color and texture given the local potato size and starch characteristics.
Peeling is performed by the AP-1000 Abrasive Peeler, optimized for the medium-to-large Vietnamese Atlantic variety. Precise abrasive settings reduce peel loss below 6 percent, important for yield and cost control. Sorting and inspection conveyors follow, where visual and mechanical grading remove undersized or defective tubers.
IL SL-1000 Slicer delivers uniform slice thickness (1.5 mm) using high-carbon steel blades, balancing throughput with minimal starch leaching. Washing and sbiancamento are handled by the WB-1000 Continuous Washer-Blancher, designed for high-starch varieties to control sugar and reduce Maillard browning. Blanching time and temperature are precisely managed (3 minutes at 85 deg C) for optimal chip color.
De-watering is achieved via the DW-1000 Vibratory Dewaterer, reducing surface moisture to below 5 percent before frying, which is vital for consistent oil absorption and crispness. The FRY-1000 Continuous Fryer operates at 180 deg C with a 2.5-minute dwell time, utilizing a three-zone oil filtration system to maintain oil quality for high-throughput frying of high-starch Atlantic potatoes.
De-oiling and cooling are provided by the DO-1000 Centrifugal De-oiler and CL-1000 Cooling Conveyor, respectively. These units stabilize oil content and enhance texture, especially important in Hanoi’s tropical humid climate. Seasoning is performed in a SE-1000 Drum Seasoner with dust extraction, ensuring uniform coverage and minimal seasoning loss.
The final steps include metal detection with the MD-1000 Metal Detector and automatic packing via the PK-1000 VFFS Packing Machine, supporting up to 60 packs per minute. This layout ensures food safety, traceability, and high output for the Vietnamese market.

On-Site Installation and Commissioning Story
The entire production line was shipped from Qingdao, China to Hai Phong Port in Vietnam, taking 10 days via sea freight. Upon arrival, the consignment cleared customs smoothly, thanks to pre-arranged documentation for FDA Vietnam and Halal compliance. Equipment was transported by truck to the Hanoi facility and unloaded over two days with local crane support.
Installation week coincided with high humidity (average 75 percent) and temperatures around 28 deg C. A key technical challenge was ensuring the fryer’s PLC-controlled ventilation system could handle the tropical environment, preventing condensation and maintaining product crispness. The engineering team recalibrated the ventilation and de-oiling sequence, leveraging real-time humidity sensors to stabilize line conditions.
During trial production, the first batch yielded chips with an average oil absorption rate of 26.8 percent and consistent golden color. The client was particularly pleased with the system’s throughput stability and minimal manual intervention. The commissioning process validated the line’s performance under tropical humid conditions typical of Hanoi.
Compliance and Certification Pathway
The line was engineered to comply with FDA Vietnam food safety regulations and Halal requirements. All process zones and documentation were aligned with QCVN 8-2:2011/BYT and Codex Alimentarius standards, ensuring traceability, allergen control, and sanitation. Halal compliance was verified by an accredited body, with all critical control points mapped and validated.
Equipment-level features included acciaio inossidabile 304 contact surfaces to support HACCP and Halal certification, color-coded tool sets to prevent cross-contamination, and a CE-marked PLC for electronic record-keeping. Segregated seasoning and packing zones ensured no cross-contact with non-Halal ingredients, supporting rapid certification during external audits.
Engineer Field Notes
Adapting the line to process Vietnamese Atlantic potatoes with 19–22 percent starch required careful tuning of the blanching and frying parameters. We reduced blanching time and slightly lowered frying temperature to prevent excessive browning, which is common with higher starch content and the larger average size grade we encountered in Hanoi. This adjustment improved color consistency and product yield.
During Halal compliance verification, we learned that documentation and physical segregation of seasoning zones are critical. Even minor lapses in cleaning records could have delayed certification. We implemented a barcode-based cleaning log for all contact surfaces, which greatly satisfied the local Halal auditor.
For long-term operation in Hanoi’s tropical humid climate, I recommend regular inspection of the fryer’s ventilation and de-oiling systems. High humidity can increase oil absorption and affect crispness, so maintaining optimal airflow and dryer settings is essential for quality and energy efficiency.
