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

- 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 cassava starch loss.

-Primary Cleaning: Use cassava dry sieve to remove dirt, weeds and mud without damaging the cassava tubers.

-Thorough Washing: Using a paddle washer in the cleaning step of cassava starch production can wash the residues on the surface of cassava roots thoroughly.

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

- Use Modern Cassava Rasper: The rasping machine in cassava starch production line can improve starch release efficiency compared to traditional method or hammer mill. Rasper is the most efficiency equipment for crushing cassava tubers in starch project.

- Water Usage Balance: Too much water dilutes cassava starch, while too little reduces extraction rate.

- Multi-stage Sieving:Use several stages of centrifugal sieves in cassava starch processing line to separate starch from fibers effectively.

- Residual Starch in cassava fiber: Re-process cassava fiber (waste pulp) to recover remaining starch.

- Fast Sedimentation:Use settling tanks or 18-stage hydrocyclone station to separate protein and cell fluid out of starch quickly, preventing fermentation.

- Proper Dewatering: Use a peeler centrifuge to reduce moisture before drying.

- Controlled Temperature (≤60°C): High heat can gelatinize cassava starch, reducing quality.

- Even Drying: Flash dryer in cassava starch production line can prevent uneven moisture content. And through automatic interlocking system, moisture content of final starch can be controlled.

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

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

- Regular Cleaning: Prevent microbial growth and clogging in pipelines and machines.

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

- Train Workers on best practices to avoid unnecessary starch loss.

- Monitor Key Parameters: Starch concentration, extraction rate, and moisture content at each stage.
