How to Troubleshoot Common Issues of a Cassava Paddle Washer?

Cassava paddle washer plays a crucial role in ensuring the products quality and food safe in different cassava products processing lines (like garri and cassava flour line). Its malfunctions will influence the quality and productivity. Next, Henan Jinrui will list the common issues of cassava paddle washer and the solutions to troubleshoot them.

Issue 1: Abnormal Operation Noise‌ of Cassava Paddle Washer

‌Motor Squealing‌

Cause‌: Insufficient lubrication or wear of motor bearings of cassava paddle washing machine.

Troubleshoot: Regularly inject high-temperature resistant grease through the oil filler port (recommended every 500 hours).

‌Paddle Friction Noise‌

Cause‌: Hard impurities (e.g., stones) in the raw cassava roots or deformed paddles

Troubleshoot: Install a cassava dry sieve for raw material pre-treatment. Inspect paddle clearance (normal range: 1–3 mm) and correct deformed paddles after shutdown.

Issue 2: Pressure Abnormalities‌ of Cassava Paddle Washer

‌Fluctuating or Intermittent Pressure‌

Cause‌: Air intake due to poor sealing in the water inlet pipeline or insufficient water supply pressure.

Troubleshoot: Check sealing at pipeline joints (use hose clamps for tightening), clean the inlet filter, and ensure water pressure ≥ 0.2 MPa.

‌Pressure Fails to Reach Rated Value‌

Cause‌: Excessive nozzle wear (recommended replacement cycle: 300 hours) or pump seal failure of cassava washing machine.

Troubleshoot: Replace with tungsten carbide nozzles of matching specifications. Inspect and replace the pump’s double-lip seal rings.

Issue 3: Reduced Cleaning Efficiency‌ of Cassava Paddle Washer

‌Excessive Residue‌

Cause‌: Low paddle rotation speed (recommended: 25–35 rpm) or uneven material density.

Troubleshoot: Adjust inverter parameters to achieve rated speed. Install flow guide plates to optimize material distribution.

‌Cloudy Cleaning Fluid‌

Cause‌: Clogged wastewater tank filters or excessive impurities in the clean water tank.

Troubleshoot: Clean the wastewater tank float daily. Wash the clean water tank filter weekly

Issue 4: Shaft End Powder Leakage‌ of Cassava Paddle Washer

Cause‌: Aged seals (typical lifespan: 6–12 months) or seal failure due to negative pressure operation4.

Troubleshoot: Replace with double-lip air-tight seals. Install a nitrogen gas sealing system (pressure: 0.02–0.05 MPa)

Issue 5: Motor Overload‌ of Cassava Paddle Washer

Cause‌: Material clogs or insufficient V-belt tension (below 30% of standard value)

Troubleshoot: Install an online moisture detector (control material humidity ≤ 15%). Adjust belt tension using an automatic tensioner.
