The right garlic sorter depends on the garlic form, the foreign material, the way the product flows and the quality standard the processor wants to protect. A machine should be selected from real material behavior, not from the word “automatic” alone.
Foreign material is not the same in every garlic plant
Some garlic lines receive stones and soil from the field. Others mainly deal with dry stems, roots, moldy pieces, broken cloves or peeled and unpeeled garlic mixed together. These defects vary in size, shape, color and surface texture.
That variation is why a general quotation for a “garlic impurity sorter” may not be enough. The first step is to identify the product form and the actual material that must be removed.
What WESORT garlic sorting equipment is designed to evaluate
WESORT’s garlic color sorting solution can be configured for visible differences in color and shape. Depending on the application, the test may include moldy garlic, peeled or unpeeled pieces, defective garlic and other visible impurities.
The system uses optical inspection to compare the product with the selected acceptance and rejection criteria. When a piece is classified as a reject, air ejection directs it away from the accepted garlic stream.
Optical sorting is most useful when the foreign material has a clear visible difference. Heavy soil, large field debris or contaminants with a similar appearance may require mechanical cleaning before or after the optical stage.
When is a chute sorter suitable?
A chute sorter is generally considered for free-flowing granular products that can move through a narrow inspection path with stable spacing. If peeled cloves or small garlic pieces flow evenly and present enough visible surface, a chute configuration may be practical.
The processor should still check whether the product rolls, overlaps or changes orientation too quickly. Stable feeding is important because the cameras need to see the surface that contains the defect.
When should a processor consider a belt-based solution?
A belt-based sorter may be considered when garlic pieces are irregular, fragile or difficult to control in a chute. The belt provides a more defined transport path and may help maintain more consistent spacing through the inspection area.
This does not mean that a belt sorter is automatically better. It may require more space and a different line layout. The correct decision depends on the product, the defect and the result of testing.
Five questions to ask before selecting the machine
- Is the product whole garlic, peeled cloves, unpeeled cloves or broken pieces?
- Are the target rejects stones, stems, roots, soil, mold or color defects?
- Is the product dry, dusty, wet or sticky?
- Does the garlic flow freely or tend to overlap?
- Will the line use positive selection, reject removal or a second pass?
Why a sample test is essential
A machine that performs well with clean, easy-to-see defects may behave differently with real garlic. The sample should contain good garlic, typical foreign material, borderline pieces and the dust or surface condition expected in production.
During the test, review foreign material remaining in accepted garlic and good garlic found in the reject stream. This provides a more useful commercial picture than looking only at the amount of rejected material.
WESORT can compare the material behavior and recommend a suitable garlic sorting machine configuration after the sample has been tested.
Conclusion
A chute sorter may suit stable, free-flowing garlic pieces, while a belt-based solution may be considered for irregular or difficult-to-control product. Neither option should be selected without checking the actual garlic, foreign material and line conditions.
