Key Strategies to Reduce Starch Loss in Cassava Starch Production

Reducing starch loss during cassava starch production is crucial for improving yield and efficiency. Here are key factors to pay attention to:

Controlling the quality of cassava is the first step to increase the yield of cassava starch. Fresh, high-quality cassava has a higher starch content, which helps reduce starch loss during cassava starch processing.

- Freshness of Cassava:Use fresh cassava roots to minimize starch degradation. Stored cassava loses starch due to respiration and microbial activity.

- Variety Selection: Choose high-starch-content cassava varieties (e.g., TME 419, KU 50).

- Remove Impurities: Dirt, sand, and peels can interfere with extraction, leading to starch loss.

In the production process of cassava starch, the peeling step is omitted in order to reduce the starch loss . Because cassava peel also contains starch components, after separation and purification, the toxins in the cassava peel can be removed. Therefore, in cassava starch production, omitting the peeling process is also a major measure to reduce starch loss.

During the cassava grinding process, the selection of appropriate grinding equipment can free the starch in the cassava better, thereby increasing the starch release rate and reducing the loss of starch during cassava starch production.

Optimal Grinding Machine-rasper

- Fine Grinding: Ensure complete cell rupture to release starch granules, but avoid over-grinding, which can break starch molecules.

- Use Modern Rasper: The machine can improve starch release efficiency compared to traditional method or hammer mill. For example, rasper designed by Henan Jinrui, the crush rate of cassava can achieve 98%, which can effectively reduce starch loss in cassava starch production.

- Water Usage Balance: Too much water dilutes starch, while too little reduces extraction rate. So Controlling the water usage balance in the grinding process, also can reduce starch loss.

The cassava starch production line adopts multi-stage separation and filtration technology, which can not only ensure the quality of cassava starch, but also reduce starch loss and maximize starch recovery. The cassava starch production line designed by Henan Jinrui adopts multi-stage separation and extraction equipment, which can effectively reduce starch loss during the production process.

- Centrifugal Sieves: Use several stages of centrifugal sieves to separate starch from fibers effectively.

- Reprocess Pulp: Residual starch in cassava fiber can be recovered through secondary extraction.

- Hydrocyclone Systems: 18 stages hydrocyclone stations enhance starch purification and reduce starch loss in wastewater.

Drying is also an important step in cassava starch processing. Optimizing starch drying technology can not only avoid starch gelatinization and ensure starch quality, but also reduce starch loss.

- Low-Temperature Drying (≤60℃): Prevents gelatinization, maintaining starch integrity.

- Flash Dryers: Ensure uniform moisture removal, improving final starch quality. Choosing suitable flash dryer can also reduce starch loss. For example, Henan Jinrui's flash dryer adopts negative press drying, can effectively avoid starch flying.

Optimized drying-flash dryer

Wastewater generated during cassava starch production usually contains residual starch. By recycling wastewater and reusing water, not only can starch loss be reduced, but water can also be saved, making the cassava starch production process more sustainable.

- Starch Recovery from Wastewater: Use sedimentation ponds or decanters to reclaim residual starch.

- Recycle Water: Reuse process water after filtration to minimize starch loss.

Regular equipment maintenance and the use of automatic control systems in cassava starch production lines also play an important role in reducing starch loss.

- Regular Cleaning: Prevent microbial growth and clogging in pipelines and machines. Microbial growth can cause starch degradation, while clogging can disrupt the production process and lead to starch loss.

- Automated Control Systems: Ensure consistent processing conditions (e.g., pH, water ratio).

Staff training for cassava starch production

- Staff proficiency: Train Workers on best practices, such as proper handling of cassava roots, efficient use of equipment, and quality control measures, can avoid unnecessary starch loss.

- Monitor Key Parameters: Continuously monitor key parameters such as starch concentration, extraction rate, and moisture content at each stage of the production process. This allows you to identify and address any issues promptly, preventing starch loss.

To reduce starch loss in cassava starch production, manufacturers must optimize raw material selection, extraction, separation, and drying processes. Implementing advanced equipment like rasper, hydrocyclone station, and flash dryer can significantly improve starch yield and profitability.
