| Condition of failure | | Cause (in processing) | remedy |
|
|---|
| Even if shutter is opened and mist adjusting knob is turned during automatic operation, neither pointer of water flow meter works nor mists. | | Power switch of water pump unit is off. | Turn on the power switch. | | Water valve in the way of line is not open. | Open the valve. | | Failure of solenoid valve for water. | Make electrical checks. | | Clogging strainer or filter. | Disassemble and remove dust,etc.
If repair is impossible, replace it. | | Clogging needle valve or nozzle. | Exchange filter element.
Disassemble and clean. |
|
| Point of water flow meter is unstable. | | Air mixed in the water. | Take out nozzle and allow water to flow unit, air is removed from the pipe. | | Clogging strainer and filter. | Disassemble and clean. | | Clogging needle valve, solenoid valve or nozzle. | Disassemble and clean. |
|
| Misting is normal but pointer of flow meter does not indicate. | | Failure of water flow meter. | Check and if impossible to repair, replace it. |
|
| Water flowrater does not increase even though the mist adjusting knob is opened maximum. | | Water pressure is too low. | Check water pump unit and adjust water pressure. | | Cause of 1.3~5. | Disassemble and clean. |
|
| Air does not come out even though the mist start button is pressed. Otherwise air quantity is small. | | Air pressure is too low. | Check pressure gauge and adjust water pressure. | | Full of water in the mist separator and micro-mist separator. | Drain it. |
|
| Misting stops during automatic operation. | | Mechanical and electrical failure of level meter. | Check and if impossible to repair, replace it. |
|
| Miting does not stop during automatic operation, even if raw material is out. | | Electrical failure of level meter. | Check and if impossible to repair, replace it. |
|
| Bran sticks to cleaned rice. | | Bran sticking to bran collecting duct. | Clean the duct. | | Lack of bran suction (static pressure) | Increase static pressure. | | Too much mist. | Adjust to the proper flow rate. | | Improper mounting of dividing rubber plate. | Adjust to the proper flow rate. |
|
| Bran sticks to the milling roll. | | Improper mounting of dividing rubber plate. | Adjust to the proper flow rate. | | Water leakage due to failure of solenoid valve. | Check and if impossible to repair, replace it. |
|
| Temperature rise of rice is too high . | | Bran sticking to the polishing chamber. | Clean the polishing chamber. | | Water supply is stopping. | Check water supply line and water pump unit. | | Screen is blinded with broken rice. | Clean the inlet. |
|
| No flow. | | Bran sticking at the inlet. | Clean the inlet. |
|
| Discharge is difficult. | | Mist leakage is due to damage of the dividing plate, and the amount added by the leakage is smaller than the standard. | Check and if impossible to repair, replace it. |
|
| Water pump intermittently stops for a while. | | Water pump gets over heating since too high water pressure. | Check water pump unit and adjust water pressure. |
