The production rate per channel can be determined by dividing the desired total
production rate by 80. Thus, feeder No. 1 and 2 should each provide 30 times this
amount and feeder No. 3 should provide 20 times this amount.
To measure the throughput for the sorter, temporarily turn the EJECTORS off so that
they will not operate. Provide a means to collect all of the product from a particular
feeder for 18 seconds. Weigh this sample and multiply by 200 to determine the
production rate per hour. Do this for all three feeders.
If the feeders are not supplying product at the same rate, change the rate by
adjusting potentiometers R1, R2, or R3 for feeders 1, 2, or 3 respectively. Turn
clockwise for more production, counterclockwise for less production (See Figure 2-
27). Check the production rate again after adjusting. Re-adjust as required until the
feeders are balanced.
When the feeder rate adjustment is complete, turn the EJECTORS back on. The FEED
RATE control(s) on the MAIN SCREEN can be used to adjust the amplitude of
vibration for all three feeders if more or less production is required.
3.2.9 ADJUSTING THE DARK TRIP CONTROL
The DARK TRIP control determines the sensitivity of the machine when removing
products that are darker than normal. Turning the control to a higher number
increases the sensitivity. More grains with small dark defects are rejected. Turning
the control to a lower number decreases the sensitivity.
The sorter should be in the DARK TRIP mode while the DARK TRIP control is being
adjusted (See Section 2.4.1).
Take samples of the accepts and the rejects to determine if the trip level should be
increased or decreased.
The sensitivity should be set so that most of the defects are removed from the
accepts without diverting too much good product into the rejects.
3.2.10 ADJUSTING THE LIGHT TRIP CONTROL
The LIGHT TRIP control determines the sensitivity of the machine when removing
products that are lighter than normal. Turning the control to a higher number
increases the sensitivity. More grains that are only slightly lighter than normal will
be rejected. Turning the control to a lower number decreases the sensitivity.
The sorter should be in the LIGHT TRIP mode while the LIGHT TRIP control is being
adjusted (See Section 2.4.2).
Take samples of the accepts and the rejects to determine if the trip level should be
increased or decreased.
The sensitivity should be set so that most of the defects are removed from the
accepts without diverting too much good product into the rejects.
