Cashew Grading & Sorting Machine
W180 to W450, sorted by size and colour
Two distinct machines: a mechanical roller grader that separates peeled kernels by size (W180–W450), and an optical colour sorter that separates by colour and size together.
"Cashew grading machine" covers two different machines, and it is worth being clear which one you are buying. The mechanical roller grader separates peeled kernels by size alone — the whole white grades W180 to W450, plus splits, butts and pieces — using rollers set to a size band. TTQ builds these from 12 to 36 axes, and they cap at about 420–540 kg/h on 36 axes. The optical colour sorter is a separate machine that grades by colour and size together, using cameras and air ejectors to pull out scorched, spotted and off-white kernels; optical sorters run far faster, up to 4 tonnes an hour. Most export lines run both: the roller grader sets the size class, the colour sorter enforces the white-grade spec.

How the two grading machines earn their place
Roller grading, by size
Rollers set to a size band separate whole kernels into W180 through W450 export classes. 12 to 36 axes, capping at 420–540 kg/h.
Optical sorting, by colour and size
A separate machine. Cameras and air ejectors remove scorched, spotted and off-white kernels, and it grades by size at the same time — up to 4 t/h.
Grade to export spec
Repeatable, machine-set grading lets you price and ship each class correctly.
Protects premium grades
Gentle handling keeps whole kernels whole through the grading stage.

Kernel grading / classification — models
Roller classifiers that sort peeled kernels into W-grades by size. More axes (rollers) = higher throughput.

Optical colour sorters — models
Camera-based sorting that separates kernels by colour class and removes defects at high speed.

The process, drawn
Grading is two machines, not one
"Cashew grading machine" is used for both, and they do different jobs at very different speeds.
- 12 axes 150–180 kg/h
- 18 axes 210–270 kg/h
- 24 axes 280–360 kg/h
- 36 axes 420–540 kg/h The TTQ ceiling
- Chute type 500–1,000 kg/h 6SXZ-63HL, 0.8 kW
- Belt type 1–3 t/h 18 cameras, 252 channels
- Large optical up to 4 t/h
Export lines normally run both: the roller grader sets the size class, the colour sorter enforces the white-grade specification. The sorter is roughly ten times faster, so one sorter serves several graders.
Where the grade value sits
The W number counts kernels per pound. Fewer, larger kernels command more — which is why whole-kernel recovery, not throughput, decides what a plant earns.
Grading order is colour, then shape, then size. Scorched grades (SW) carry the same counts at a lower price. Source: AFI standards.
Where it fits in the process
Grading and sorting follow peeling and precede vacuum packing. The graded, colour-sorted kernels are what the packing line seals into export-ready lots.
