PRECISION ROAST / Selection / CLASS AND APPLICATION
SORTINGGREEN COFFEE
Before roasting, sorting helps to form a controlled input batch: separately by apparent defect and separately by size if both tasks are really needed.
Describe the origin, humidity, dimensional distribution, type and proportion of the target defects, as well as the acceptable useful yield. The machine is tested before the coffee roaster on representative bags: the result affects not only the purity of the raw materials, but also the load, profile and material balance of production.

From measurable defect to testable specification
01
Put the task to coffee roaster
Sorting a green coffee should have a measurable input and output, record the batch mass, the proportion of the target defect, the size distribution and the allowable amount of good beans in the bay, and then the result can be attributed to the actual output of the roast, not the visual impression of the demonstration.

02
Do not mix color and size
The optical machine detects a predetermined apparent difference, the sieve machine separates the geometric fractions. For a batch with both problems, the stages can complement each other. The order is chosen by testing and planning, given the excess overload and possible damage to the grain.

03
Check for defect and useful exit
A high drop rate does not equal a good sorting. Disassemble the accepted and rejected fractions, count the missed target defect and the suitable grain in the waste. Repeat the stable result on several deliveries under the same protocol.

04
Link sorting to storage and roasting
Before and after the car, you need tagged containers, lot traceability, and re-mixing protection. You need to coordinate the transmission height to the coffee roaster bunker, loading rate, dust removal and line behavior when the next node stops.

04/sources and evidence
What is confirmed and what else needs to be checked
The catalog below includes only models whose normalized application data specifies green-coffee. Models with no documented coffee stage are deliberately excluded.
02
Different principles
Optical and screen can coexist, because the filter specifies the stage of the coffee, not the mechanism. Compare them only after the specific task is formulated.
03
Checking the batch
The supplier listing confirms the claimed use, but not the effectiveness on the specific origin, humidity and set of defects.

There's no universal order. Precalibration can stabilize the optical feed, but adds overload; test both options and compare total output, defects and pace.
Can I adjust the car for all the defects of green coffee at once?+
You can't assume this without proof. Make a list of target defects, prepare benchmarks and confirm the result for each criterion and batch.
Do I need pre-cleaning?+
It is often useful for stable supply and protection of equipment, but the composition of the line depends on the input contamination.
Why are there few models in the collection?+
The filter doesn't guess the stage by the photo or the name, and the model only appears here when the green coffee application is explicitly confirmed in the data collected.
Check the sorting on your lot
Lock the input, each output, missed defect, false selection, steady pace, cleaning and line interfaces.
