Troubleshooting Common Issues in Cassava Starch Extraction Equipment

-

 

Cassava starch extraction is a complex process involving several stages, including cleaning, rasping, extraction, purification, dewatering, and drying. Each stage relies on specialized equipment, and issues can arise at any point, affecting the quality and yield of cassava starch. Below are common issues in cassava starch extraction equipment and troubleshooting tips:

Issue 1:Low Cassava Starch Yield

Possible Causes:

Inefficient rasping or grinding of cassava roots.

Poor extraction efficiency in the extraction sieve or centrifuge sieve.

Incomplete separation of starch from fibrous material.

Troubleshooting:

Check the cassava rasping machine for worn-out blades or improper settings. Replace or adjust as needed.

Ensure the extraction sieve or centrifuge sieve is functioning correctly and is not clogged.

Optimize water usage during extraction to improve cassava starch separation.

Issue 2: High Fiber Content in Cassava Starch

Possible Causes:

Inadequate separation of fibers during starch extraction.

Damaged or improperly sized sieve mesh.

Troubleshooting:

Inspect and clean the extraction sieve or centrifuge sieve regularly.

Replace the sieve mesh if it is torn or has oversized holes.

Adjust the water flow to ensure proper washing and separation of fibers.

Issue 3: Starch Loss in Wastewater

Possible Causes:

Excessive water usage during extraction.

Poor settling or dewatering efficiency.

Troubleshooting:

Optimize water usage to balance cassava starch extraction and water conservation.

Check the settling tanks or hydrocyclone stations for proper operation and ensure they are not overloaded.

Inspect and clean the peeler centrifuge regularly to make sure its normal dehydration.

Use flocculants to improve starch recovery from wastewater.

Issue 4: Clogging of Cassava Extraction Equipment

Possible Causes:

Accumulation of fibrous material or starch residues in sieves, pipes, or pumps.

Inadequate cleaning of cassava starch extraction equipment between batches.

Troubleshooting:

Regularly clean sieves, pipes, and pumps to prevent blockages.

Install filters or screens to trap large particles before they enter critical cassava starch extraction equipment.

Use high-pressure water or air to clear clogs.

Issue 5: Poor Cassava Starch Quality

Possible Causes:

Contamination from soil, roots, or equipment.

Inefficient purification or washing processes.

Microbial growth due to inadequate drying or storage.

Troubleshooting:

Ensure thorough cleaning of cassava roots before processing.

Optimize the purification process, like the use of 18-stage hydrocyclone station.

Use a negative pressure flash dryer to dry starch to the recommended moisture content (typically 12-14%) and store in a cool, dry place.

Issue 6: Overheating of Starch Equipment

Possible Causes:

Excessive friction in cassava rasping or grinding machines.

Poor lubrication or maintenance of moving parts.

Troubleshooting:

Regularly lubricate bearings and other moving parts.

Monitor equipment temperature and reduce load if overheating occurs.

Ensure proper alignment of components to reduce friction.

Issue 7: Slow Processing Speed

Possible Causes:

Overloading of cassava processing equipment.

Inefficient motor or power supply issues.

Troubleshooting:

Avoid overloading equipment by feeding cassava at the recommended rate.

Check the motor and power supply for proper functioning.

Upgrade cassava starch extraction equipment if the current capacity is insufficient for the required throughput.

General Maintenance Tips:

Regular Cleaning: Clean all cassava starch extraction equipment after each use to prevent residue buildup and contamination.

Lubrication: Regularly lubricate moving parts to reduce wear and tear.

Inspection: Conduct routine inspections to identify and address issues early.

Operator Training: Ensure operators are well-trained in equipment operation and maintenance.

Cassava Production Guide in the Philippines

-
Image
  Cassava is a vital crop in the Philippines, serving as a primary source of food and income for many farmers. This guide provides essential information on cassava production, include planting, harvesting and processing, to help Filipino farmers enhance their yield and profitability. Cassava tubers Climate and Soil Requirements: Cassava thrives in tropical and subtropical climates. It prefers well-drained, sandy loam to clay loam soils with a pH range of 5.5 to 6.5. Variety Selection: Choose varieties that are high-yielding, disease-resistant, and suitable for the local climate. Recommended varieties in the Philippines include CIAT 30576, TMS 30572, and KM 94. Seed Preparation and Planting: Use healthy, disease-free cuttings for planting. Cuttings should be about 20-30 cm long with at least 5-7 nodes. Plant cuttings vertically or at a 45-degree angle, ensuring that at least two nodes are buried in the soil. Land Preparation: Plow and harrow...
