Installation of Auxiliary Facilities

Users must use water and oil-free air compressors, and install filters (as we do). All the Air components must be connected with each other with galvanized pipes, rubber hoses, or pipes of higher classes with proper diameters. It is recommended to install the air compressor at an insulated room near to the color sorter (no more than 15 meters), thus reducing noise while offering adequate pressure.
The filter installed in the color sorter should a typical operating temperature of 0 ℃-40 ℃; as in winter (especially in the north region) when room temperature tends to drop below 0 ℃, the filter should be air-dried after the sorting operation, and heat insulation measures should be taken to keep it above 0 ℃. Otherwise, it may lead to freezing of pipes and filter elements, consequently inhibiting the air flow and causing damage to the filter elements.
Air compressors should be placed in well-ventilated, clean places with even ground and low air humidity. Environmental temperature should be controlled below 40 ℃, and keep the equipment 80 cm away from the wall to facilitate maintenance and inspection; pay attention to let the drain outlet face outside, and avoid exposing it to direct sunlight and rain.
The first-stage coarse filter should be installed at the outlet of air compressors or air tanks, so as to utilize the functions of the filter as much as possible.
In cases of any significant air pressure drop indicated by the pressure gauge (for example, dropping to less than 0.1 MPa when the color sorter working pressure is between 0.15-0.1 8 MPa), the filter elements on first-stage filters should be replaced immediately. Any elimination or reduction of filter elements may adversely affect or damage the filter parts and jet valves in the second-stage filters.
Rubber hoses can be connected to the outlet pipes of the air compressors to avoid vibrations.
Before conduction connection for all the pipes, scraps and dusts must be removed from the pipes, so as to avoid damage to jet valves.

Color Sorting Process

After moved by a lifter into color sorters from the top, grains will go through a two-stage sorting process. At the first stage, good-quality grains will be sorted out from inferior grains; then at the second stage, the inferior grains will be subject to a secondary sorting action after being moved into a secondary-sorting channel, whereby good-quality grains will be further sorted out and moved by a lifter back to the inlet of color sorters for re-sorting, and inferior grains will be taken as waste and discarded.

FAQ

The equipment involves an automatic fault detection and alarm function, and the fault parts will be indicated by an indicator light or shown by a color display. Users can usually solve the problem by themselves.
Faults Causes Solutions
Air leakage of solenoid valves Foreign matters found in valves Blow air into the valve in a reverse direction for repeatedly test
Wear of valve components Replace worn parts
Solenoid valves fail to work Poor contact of valve wires  Re-plug or repair poor contact parts to enable good contact
Damaged control circuit boards Replace control circuit control boards
An inadequate amount of air injection for solenoid valves Solenoid valves are not switched to the assigned location Re-adjust or replace solenoid valves
Air pressure is too low Check the pressure gauge and corresponding air piping
Rice leaps on rice channels The water content in rice is excessively high Dry the rice for re-sorting
Ashes on rice channels cake Clean the rice channel with a piece of soft cloth
Scratches occur on rice channels

Replace rice channels with new ones

Frequent action of color sorting indicator lights and electromagnetic valves (fluorescent lamps)

Fluorescent lights are burn out Replace fluorescent lamps with new ones
Color sorting modes are not set correctly Set color sorting modes correctly
Damaged power supplies for fluorescent lamps Replace power supplies
Background plates get stuck Restore stuck boards
Rice sorting waves are not correctly set Re-adjust background plates
Fluorescent lamps are not lightened Re-lighten fluorescent lamps
Circuit fault reminders appear Circuit fault Please contact us
Poor rice sorting results on channels at both sides Fluorescent lamps are black at both ends  Replace fluorescent
The equipment don’t work at all Sensitivity is too low Adjust sensitivity
Background plates are improperly adjusted Adjust background plates
Sorted grains are increasingly inferior ones during a certain period Dust accumulates on glass plates in the sorting chamber Wipe off dust with a clean piece of cloth
Parameters of sensitivity and background plates change Re-set parameters
Rice channels are unheated Check the heating system

Dust wipers are damaged and aged

Replace dust wipers
Poor sorting results on a single side of the system Poor cleaning results due to inappropriate action of rodless cylinders Adjust the wiping speed of dust wipers
Color Sorters often shut down   Excessively high sensitivity; re-adjust the sensitivity Background plates (or waveforms) are not adjusted properly
Re-adjust Background plates Excessively high content of yellow grains
Reduce output Inadequate air supply pressure
Check the air pressure and air passage to find out they are proper; re-adjust the air passage Protection of air pressure often occurs
Try to make pipes unblocked clean or replace relative filter elements
