Product Overview – A Complete Line for Delicate Litchis
Litchis (lychees) have thin skin and delicate flesh. They require gentle handling to avoid bruising and browning. Our litchi grading and packing line is designed specifically for this challenging fruit.
The line includes:
Component | Function |
Hopper & elevator | Gentle feeding – low drop height |
Inspection table | Manual removal of defective or damaged fruit |
Roller grader | Size sorting by diameter (3–6 grades) |
Automatic box fill & weigh | On grade exits |
Control cabinet | Touch screen – all settings in one place |
Optional Front-End Modules
Depending on your fruit condition and market requirements, you can add:
Option | Description | Benefit |
Pre-grading destemming table | A long, 3-tier table placed before the grader. Workers manually remove stems and leaves, separating clustered litchis into individual fruits. | Cleaner fruit, better grading accuracy, prevents jamming. |
Washing section | Water tank + brushes + sprayers | Removes dust, debris, and field heat. |
Pre-cooling | Cold water soak or forced air cooling | Extends shelf life, maintains color. |
💡 The destemming table is highly recommended for freshly harvested litchis that come in with stems and leaves attached.

Frequently Asked Questions
Key questions customers usually ask before choosing this solution.
Why is gentle handling so important for litchis?+
Litchis have thin, delicate skin and brown easily when bruised. Our roller design and low-drop elevator prevent damage that causes browning.
What is the difference between the two packing options?+
Automatic fill & weigh: Belt fills box to preset weight – best for 2kg+ boxes, high volume. Independent packing table: Workers manually pack and weigh – best for premium, small packs (500g/1kg), and branded products.
Can I add pre-cooling to the line?+
Yes. We can integrate a cold water soak or forced air pre-cooling section before grading. This is highly recommended for export litchis.
Can this line handle other fruits?+
Yes. It also works for longan, rambutan, cherry tomato, jujube, and similar-sized fruits.
