As Taiwan's grapefruit season gets underway, packers are weighing two grading approaches — diameter sorting for high volume or weight grading for export precision.
Taiwan's Grapefruit Season: A Growing Opportunity
Taiwan's warm climate and fertile soil make it ideal for grapefruit cultivation. The island's grapefruits are known for being juicy and sweet, and they have found ready buyers in both domestic and export markets.
For local packers, the question is no longer whether to mechanize grading — it's which grading method delivers the right balance of speed, accuracy, and cost for their specific market channels.
Some packers sort by diameter, using size grades such as 3L (100mm), 2L (95–100mm), L (86–95mm), M (79–86mm), and S (below 79mm).
Others, particularly those supplying export markets, need finer grading by weight to meet supermarket specifications.
Two Grading Approaches for Two Different Markets

Drum Grader vs. Electronic Sorter: Which One Fits Your Operation?
Comparison | Drum Grader | Electronic Sorting Line |
|---|---|---|
Sorting principle | By diameter (drum holes) | By weight (±2g precision) |
Capacity | Very high — 20 t/h | 10,000 pcs/h |
Number of grades | 3 sizes (9 exits) | 6–12 weight grades |
Accuracy | Moderate | High (±2g) |
Best for | Basic size grading, high volume | Premium markets, export, uniform weight packing |
Investment | Lower | Higher |
The choice depends on your target market. Selling to local wholesale? The drum grader gives you the speed you need at a lower cost. Exporting to supermarkets? The electronic sorter delivers the precision that buyers demand.
Whether you need high-volume diameter sorting or precision weight grading, Fstsort has a solution.
