Optical, or color, sorting recognizes visible differences. Mechanical calibration divides the flow by size. These are different tasks that sometimes require two consecutive machines.
Choose equipment from product stage and measurable defect, not from the general word "sorting." For green and roasted coffee, there are differences in permissible losses, serving, contamination and place in the process. Performance is checked along with selection quality and false marriage, and cameras, sensors, compressed air, cleaning and line interfaces are fixed in the specification.

Stage, principle, quality of selection and full integration
01
Separate green and roasted coffee
Green coffee is sorted to roast to prepare a more homogeneous batch and remove predetermined defects or impurities. Roasted coffee is tested after cooling, taking into account the fragility of the grain, oils, dust and proximity of the packaging site. Application for use at one stage cannot be automatically transferred to another.

Optical sorting means color
In the catalog, the terms "optical sorter" and "color sorter" are used as names for the same class: cameras or other sensors observe individual particles, the algorithm matches the signal with the setting, and the selection system outputs the marked material from the main stream.

03
Screen calibrated by size mechanically
A sieve size graders splits the grain through the holes of a given geometry, and the result is determined by the configuration of the sieve, the number of decks, the feed, and the actual distribution of the batch by size, and it doesn't evaluate color, and it doesn't promise to remove a defect that's invisible to the sieve.

Consider false marriage with productivity
The maximum flow without the quality criterion does not describe the useful work. On the test, the input, the received product and the rejects are weighed, then the missed defects and the suitable grain in the waste are checked, the setting is repeated on several representative batches, not only on the prepared demonstration sample.

Check air, cameras and surveillance conditions
Pneumatic selection requires pressure, flow rate, quality and stability of compressed air. The optical part requires clean windows, stable lighting and access to calibration. Ask not only the name of the sensor or camera, but also the procedure for checking the result after changing the recipe.

Are optical and color sorters different machines?+
In this section, these are synonyms of the same class: the system observes the grain with cameras or sensors and separates the particles according to a tuned optical feature.
Will a sized size graders remove the color defect?+
Only if the defect coincides by chance with the dimensional fraction being separated.Sito measures the passage through the hole, not the color, so you need optical control for color difference.
Can you compare cars to the maximum kg / h?+
Not without the same product and the same quality criteria. Match the steady flow with the purity of the accepted fraction, the omission of defects and the false selection of suitable grain.
Does a color sorter always require compressed air?+
For pneumatic cut models, yes, but the requirements are different: Ask for pressure, flow rate, air quality and system drawdown behavior; no field in the listing does not mean no requirement.
Where to put sorting in the production line?+
The position depends on the task. Green raw materials are usually tested before roasting, roasted after cooling; before and after the machine, you need a coordinated feed, accumulation, aspiration and safe discharge.
Put the sorting in full production flow
Coordinate feeding, air, aspiration, output fractions, accumulation, cleaning and locking prior to model selection.
