| Condition of failure | | Cause (in processing) | remedy |
|
|---|
| Poor husking ratio | | Insufficient roll pressure. | Adjust the pressure to increase the pressure as to set the husking ratio at about 90% without any damage on the grain skin. | | High water content of the paddy. | Measure the water content, and adjust it to a right level. | | Worn rolls | If the main shaft roll is smaller in diameter than the countershaft roll, exchange the right and left sides.
Replace them with new ones. | | Excessive feed rate. | Decrease feed rate using the feed rate adjusting handle. | | Belt slippage | Tight belt as per 5,6,8. |
|
| much husk included in the husked rice | | Maladjusted wind-sorting section. | Adjust the valve. | | Belt slippage. | Tighten the belt. | | Husking is often interrupted. | Use the valve to decrease the feed rate, and avoid any long duration of interruption wherever possible. | | Too much feed rate. Blocked louver. | Clean the louver. |
|
| Des not power on (pilot lamp does not illuminate | | The power switch of the paddy husker control panel is not turned on. | Turn on the switch. | | Broken cable. | Check the conductance of power cable. | | Blown fuse (F1) on the front of the control box. | Replace the fuse(1A) |
|
| Rolls do not open/close. | | Fault with the air cylinder (for rolls). | Replace the air cylinder. | | Fault with the speed controller. | Replace the speed controller. | | Fault with the regulator. | Replace the regulator. | | Excessive tension of the driving Hex. | Adjust the belt tension. | | Bolt, or wrong belt routing. | Check the belt routing, and reinstall the belt if necessary. | | Fault with the air valve. | Replace the air valve. |
|
| Neither shutter nor rolls function. | | Fault with the HAND/AUTO change over switch. | Replace the switch | | Blow fuse on the panel. | Replace the fuse(1A). | | No or sufficient air feed. | Feed air 5kgf/cm²or more. | | Fault with the solenoid valve | Replace the solenoid valve. |
|
| Shutter does not open. | | No paddy contained in the husker hopper. | Supply the paddy. | | The time set on the timer has not elapsed yet from the paddy began the accumulating. | Wait until the time comes. | | The paddy separator hopper is full. | Wait unit the hopper becomes empty. | | Fault protection circuit tripped. | Repair the fault. | | Fault with the husker hopper lower limit level gauge. | Replace the level gauge. | | Fault with the air cylinder. | Replace the air cylinder. | | Ball valve closed. | Open the ball valve. | | Low air pressure. | Wait until the air pressure recovers. |
|
| Shutter does not close. | | Fault with the upper limit level gauge of the paddy separator machine hopper. | Replace the level gauge. | | Low air pressure. | Check and adjust the air pressure. | | Fault with the air cylinder and solenoid valve. | Replace the air cylinder and solenoid valve. |
