Analysis of the specific causes of the phenomenon and solutions

1. The color sorter shows insufficient air pressure

A The air compressor is working abnormally or a motor does not work, causing the air supply pressure to be abnormal. Check the air compressor to make its working pressure reach the normal range

B The air compressor is working normally. Too far air source lines, too thin conveying pipelines, and incomplete opening of ball valves can easily cause air supply and display insufficient air pressure.

C In the cold season, the filter does not drain water and causes freezing, which can block the flow of airflow, resulting in insufficient air supply and display air pressure for the color sorter

D. There is a very serious air leakage in the conveying pipeline or the color sorter, which can also cause insufficient air supply and display air pressure.

E The raw grain contains yellow or abdomen with a large amount of white, resulting in high air pressure in production, and insufficient air supply and display air pressure. Please lower the sensitivity or reduce the production flow

F The raw grain contains yellow or white belly, and the sensitivity is adjusted very low. If the background plate is not adjusted properly, it will also cause a large amount of air, and the air supply and display air pressure are insufficient. Please re-adjust the background plate.

G. The raw grain contains yellow or white abdomen with moderate amount, large flow rate, high sensitivity, and the background board is not adjusted to the best, which will also cause a large amount of air consumption, and the air supply shows insufficient air pressure

H. Too much dust in the outdoor glass of the color sorter causes the color sorter to spray randomly, and the air consumption increases, resulting in insufficient air supply and display air pressure. Please clean the sorting outdoor glass

L In the normal sorting mode, the brightness of the LED light board is abnormal or not bright, causing the color sorter to spray randomly, and the air consumption is increased, resulting in insufficient air supply and display air pressure. Please replace the LED light board

2. The color sorting machine is basically not color sorting

A Forgot to turn on the "start" button during production, resulting in no color selection

B The background board is not adjusted properly, resulting in a small sorting volume of the color sorter. Please re-adjust the background board

C The sensitivity setting is too low, resulting in a small sorting volume, please increase the sensitivity

D The LED light board of the color sorter is not bright enough, please replace the LED light board

E The air supply pressure of the color sorter is insufficient, resulting in a small sorting volume, please check whether the air circuit is normal

3. Color sorter chute (rice path) jumping rice

A The rice track is scratched, please replace it

The humidity of B rice is relatively high, causing the rice path to be stuck with rice dust and the rice flow is not smooth. Please clean the rice path (wipe with a soft cotton cloth)

4. The single-sided effect of the color sorter is not good

A. Inadequate cleaning of the rodless cylinder (insufficient cleaning air pressure or problem with the cleaning brush), resulting in a lot of dust on the outdoor glass of one side of the sorting, and the color selection effect is not good. B Because the feeding pipe is not in the primary or secondary rice hopper In the middle position, the amount of rice under the leftmost or rightmost rice path of the rice color sorter is large, and the color sorting effect is not specified well.
