Client Background and Market Context
The client, a diversified agro-processor and snack manufacturer based in Accra, Ghana, operates multiple food businesses with a focus on value-added local crops. Facing rising demand for packaged snacks, they sought to add cassava chips to their portfolio. Their procurement motivation was to scale up production, ensure Halal compliance, and meet GSA food safety standards for national and export markets.
According to Statista, the Ghanaian snack market was valued at USD 180 million in 2023 with a 7.2 percent CAGR. Local competitors such as Yazzy Snacks, Kasapreko Foods, and Champion Chips dominate urban retail. The client’s timing was strategic, aligning with surging consumer demand and favorable regulatory incentives for local processing.
Pain Points and Procurement Requirements
Prior to this investment, the client struggled with inconsistent chip quality, high oil absorption rates, and downtime caused by manual processing. They also faced challenges in meeting Halal and GSA certification due to equipment gaps and lacked responsive after-sales support.
- High Capacity Output: The line must reliably deliver at least 1,000 kg per h finished chips to meet market demand.
- Low Oil Absorption Rate: Finished chips must have oil content below 30 percent to satisfy quality and health standards.
- Energy Efficiency: Equipment should minimize electricity and gas consumption for competitive operating costs.
- Halal and GSA Compliance: All contact surfaces and processes must align with Halal and Ghana Standards Authority requirements.
- Rapid After-Sales Response: Local operators require technical support within 24 hours to minimize downtime.
Engineering Solution and Process Description
The production process begins with raw cassava intake, where roots are unloaded and conveyed to the QXJ-1000 Peeling Machine. This equipment uses abrasion rollers to remove outer skin efficiently, minimizing starch loss, which is critical for the Mondial variety’s 19 percent starch content.
Next, the peeled roots pass through the FSL-1000 Sorting Conveyor for manual inspection and removal of defects. This ensures only uniform-sized tubers progress, optimizing slicing consistency and downstream throughput.
Itu QS-1000 Slicer applies adjustable blade settings to achieve a 1.2 mm chip thickness, ideal for the average cassava size grade in Ghana. Uniform slicing is essential to control moisture loss and achieve even frying.
Sliced cassava is washed in the QXJ-800 Washing Machine to remove surface starch and debris. Effective washing prevents excessive oil absorption and browning during frying, especially important with high-starch raw material.
The slices are then blanched in a BLJ-1000 Continuous Blancher at 85 deg C for 2 minutes. This step inactivates enzymes and stabilizes color. Rapid de-watering via the TSJ-1000 Dewatering Centrifuge follows to reduce surface moisture to below 5 percent.
Itu frying process is performed in the YZJ-1000 Continuous Fryer, maintaining oil at 180 deg C. The design supports precise temperature and dwell time control, critical for minimizing oil uptake in the Mondial variety.
After frying, the de-oiling stage uses the TSJ-800 De-oiling Centrifuge, which spins chips to remove excess oil, achieving a final oil absorption rate of 28 percent.
Chips are conveyed to the cooling tunnel (LQJ-1000) to bring product temperature down for seasoning in the FLJ-500 Drum Mixer. Metal detection (MD-800) ensures food safety before automatic packing in the DZ-1000 Packing Machine.

On-Site Installation and Commissioning Story
The entire line was shipped from Qingdao, China to Tema Port in 32 days. Upon arrival, customs clearance in Ghana proceeded smoothly due to pre-arranged documentation. Unloading at the Accra site was completed within one day, with all crates accounted for and no transport damage.
During installation week, the team faced a challenge with voltage stabilization due to local grid fluctuations. Our engineers deployed an industrial-grade AVR system, ensuring stable 230V 50Hz input for all key equipment. Additionally, the high humidity (55 percent) and average temperature of 24 deg C required recalibration of the de-oiling and cooling modules to maintain chip crispness.
The trial production phase commenced under typical Accra weather: tropical, 24 deg C, and 55 percent humidity. The first batch achieved 1,000 kg per h throughput and a 28 percent oil absorption rate, exceeding client expectations. The client was especially impressed by the crispness and uniformity of the finished chips.
Compliance and Certification Pathway
The line was engineered to fully comply with GSA (Ghana Standards Authority) food safety requirements and Halal standards. All production stages were documented for traceability, and the solution was audited according to GSA 231:2012 and CODEX STAN 1-1985 for food contact materials. Halal compliance was ensured through dedicated ingredient controls and segregated process flows.
Equipment features supporting certification included baja tahan karat 304 contact surfaces for HACCP and GSA, color-coded process zones for Halal segregation, and CE-marked PLCs for export readiness. All lubricants and cleaning agents used were Halal-certified, and food-grade documentation was maintained for all components.
Engineer Field Notes
Adapting our process to the local Mondial cassava variety with its 19 percent starch content and variable size required fine-tuning the slicer blade gap and frying dwell time. We found that reducing the slice thickness to 1.2 mm and slightly increasing blanch time improved both crispness and oil uptake control.
A critical lesson during Halal compliance was the need for full segregation of cleaning equipment and color-coded utensils. During the GSA audit, we demonstrated our documentation and traceability system, which was key to passing on the first attempt.
For long-term operation in Ghana’s tropical climate, I recommend routine maintenance on de-oiling and cooling modules. High humidity can impact chip texture if airflow is not closely monitored. We programmed extra humidity sensors to help operators adjust in real time.

FAQ for Buyers
What is the price range for a 1,000 kg per h fully-automatic chips line in Ghana?
The typical investment for a 1,000 kg per h fully-automatic cassava or potato chips line in Ghana is between USD 360,000 and USD 420,000 depending on automation level and auxiliary equipment. This includes core processing, packing, and initial spares. Optional features such as smart IoT modules or extended warranties may add to the budget.
What is the lead time and shipping duration to Tema Port?
Standard lead time for manufacturing is 90 to 120 days after contract and down payment. Shipping from Qingdao to Tema Port typically takes 32 days by sea. Customs clearance and inland transport add another 5 to 7 days, so plan for a total project timeline of around 5 to 6 months from order to commissioning.
What are the electricity and gas operating costs under Ghana conditions?
At Ghana’s average industrial electricity price of 0.12 USD per kWh and LPG at 0.43 USD per m³, daily utility costs for a 1,000 kg per h line running 16 hours are around USD 178 for electricity and USD 94 for gas. Energy optimization features can reduce these numbers by up to 8 percent.
Is Halal and GSA food safety compliance feasible for this line?
Yes, all contact surfaces are baja tahan karat 304, and the line is engineered for Halal and GSA compliance. Documentation and process segregation make GSA 231:2012 and Halal audits straightforward.
