Potato starch production. A guide to consistent, high-quality yields

Rising operating costs, inconsistent starch quality and increasing sustainability demands are common challenges faced by many facilities in the potato starch industry. These challenges become even more critical during high-pressure campaign operations, where maintaining uninterrupted production is essential to meeting client demands and ensuring profitability. We partner with Flottweg to provide efficient and sustainable solutions that help you optimize every aspect of your production process, from maximizing starch yields and minimizing water usage to ensuring reliable, consistent 24/7 operations.

 

 

 

4 main challenges of potato starch production and how to overcome them

 

 

Rising operating costs in potato starch production

 

The challenge: High energy consumption, extensive water usage, and frequent maintenance are some of the biggest contributors to rising operational costs. With campaigns often running 24/7 for months, minimizing expenses is essential for maintaining profitability.

 

Our solution:

 

• Flottweg decanters: These energy-efficient centrifuges optimize the separation of solids and liquids, reducing the energy required for downstream processes. Their robust design minimizes wear, lowering maintenance costs.

 

• Flottweg belt presses: They achieve a high dry matter content of up to 90%, efficiently extracting excess moisture from potato pulp. This significantly reduces the energy required for thermal drying, maintains the quality of the pulp and cuts transport costs by decreasing the volume and weight of the material.

 

• Water recycling systems: Flottweg decanters efficiently separate vegetable water from the potato pulp during processing. This recovered water can be clarified and reused in washing or other production stages, reducing the reliance on fresh water.

 

The impact: By implementing Flottweg solutions, starch plants can achieve substantial cost savings while maintaining operational efficiency, allowing them to pass on competitive pricing to their clients.

 

 

Inconsistent potato starch quality

 

The challenge: Variability in raw potato quality, process inefficiencies and impurities can lead to inconsistent starch output, impacting client satisfaction and downstream usability.

 

Our solution:

 

• Flottweg nozzle separator: The Flottweg nozzle separator is designed to efficiently wash and concentrate starch, ensuring high purity and consistency. Its advanced disc stack technology allows for the separation of fine solids, while the continuous solids discharge system maintains uninterrupted performance, delivering a final product that consistently meets the stringent quality standards of industries such as food, paper, and pharmaceuticals.

 

• Process optimization audits: Our process optimization audits are key to identifying and addressing factors affecting starch quality at every stage of production. From raw material variability to separation efficiency, we analyze key quality drivers and suggest tailored solutions.

 

• Real-time monitoring systems: Real-time monitoring ensures consistent starch quality by continuously tracking critical parameters like concentration, impurity levels and separation efficiency. Automated adjustments stabilize processes, preventing fluctuations and maintaining uniformity. This proactive approach minimizes impurities and ensures high-purity starch.

 

The impact: Consistently delivering high-quality starch enhances plants’ reputation as reliable suppliers, which strengthens existing relationships and opens doors to long-term partnerships and new business opportunities.

 

 

Complying with environmental & sustainability standards in potato starch facilities

 

The challenge: Environmental regulations and the demand for sustainable practices are changing the potato starch industry constantly. Starch plants must address challenges such as reducing water consumption, managing waste responsibly and improving energy efficiency, all while maintaining operational effectiveness.

 

Our solution:

 

• Water management: Flottweg decanters and nozzle separators efficiently separate vegetable water from potato pulp, enabling its reuse for washing and other production stages. This reduces fresh water consumption and minimizes wastewater output, cutting costs and meeting regulatory standards.

 

• Byproduct recovery: With advanced separation technology, Flottweg decanters extract valuable proteins from vegetable water. These proteins can be processed as an additional revenue stream or repurposed, reducing waste and improving overall resource utilization.

 

• Energy-efficient design: Flottweg machines are engineered for low energy consumption through optimized drives and lightweight construction. Their durability and minimal wear ensure long-term operational sustainability while maintaining consistent performance.

 

The impact: By adopting sustainable practices, starch plants achieve more than just regulatory compliance. Efficient resource management and eco-friendly production processes enhance their reputation with eco-conscious clients and consumers, positioning them as forward-thinking industry leaders.

 

 

Reliable potato starch production during campaign seasons

 

The challenge: During campaign operations, starch plants operate 24/7 for months to meet production demands. Equipment failures or unplanned downtime in this critical period can lead to financial losses, missed targets and potentially damaged client relationships.

 

Our solution:

 

• Robust design for continuous operation: Flottweg decanters, nozzle separators and belt presses are engineered with high-quality materials to withstand the rigorous demands of extended campaign operations. Their durable construction ensures consistent performance, even under the strain of 24/7 use.

 

• Simplified maintenance: Easy-to-access components and quick-clean features ensure that essential maintenance can be performed with minimal downtime. For example, belt presses are equipped with continuous belt-cleaning systems that reduce residue buildup, keeping machines running smoothly throughout the campaign.

 

• Efficient cleaning protocols: Flottweg machines are designed to meet the strict hygienic standards of highly regulated industries such as food, biotechnology, and chemicals. Constructed with high-quality stainless steel and adhering to “Hygienic Design” principles, they ensure deposit-free operation and easy cleaning. With CIP-capable components and innovative solids chambers, Flottweg nozzle separators integrate seamlessly into existing cleaning processes, maintaining product purity and operational efficiency.

 

The impact: Starch plants can maintain uninterrupted operations throughout demanding campaign periods. This ensures production targets are met without costly delays, protects client relationships with reliable deliveries and minimizes operational risks.
