Bubble Cleaning
By generating numerous dense, fine bubbles in the water, the dragon fruit tumbles and moves forward. This effectively removes and shakes off mud, dust, and other impurities adhering to the surface and deep within crevices, achieving a deep, gentle, and thorough cleaning.
- The physical impact of bursting bubbles effectively removes stubborn dirt from crevices that are difficult to reach by hand brushing.
- Bubble cleaning avoids the scratches and abrasions that mechanical brushing can cause to the delicate dragon fruit skin.
- Lighter impurities (such as grass clippings and some diseased fruit) float to the surface and are automatically skimmed off, improving overall cleaning efficiency.
High-Efficiency Drying
After washing, the dragon fruit enters the drying line, where it is processed by a filtered, uniform, and gentle air curtain to quickly and thoroughly dry the surface moisture, ensuring the fruit is dry and ready for precise weight grading.
- Complete removal of surface moisture eliminates weight measurement errors caused by water residue, guaranteeing accurate grading.
- Rapid drying effectively prevents bacterial and mold growth, extending product shelf life.
- The dried fruit fully showcases its bright, natural color.
Weight Grading
After being individually sorted by surface-dried dragon fruit, they pass through high-precision weight sensors one by one. The system collects weight data in real time, compares it with preset grades, and instructs the sorting mechanism to precisely guide the fruit into the corresponding channel.
- The weight sorting error is extremely small, ensuring that the fruit height is uniform within each grade.
- Advanced algorithms and rapid execution mechanisms ensure extremely high sorting accuracy and efficiency even at high speeds.
- Up to several weight grade standards can be easily set and adjusted through the human-machine interface to adapt to diverse market demands.
Collection and Packaging
Dragon fruit of different grades is collected and placed into corresponding collection bins via independent soft-cushioned chutes or directly connected to automated packaging equipment, achieving a seamless transition from sorting to packaging.
- Independent output channels ensure complete separation of fruits of different weight grades, guaranteeing uniform specifications.
- The chutes and cushioning system minimize mechanical damage during fruit rolling and falling.
- Connecting to an automated packaging line enables continuous production, significantly saving labor and time costs.
