Each level has a different weight and a different selling price, which facilitates the subsequent pricing of different levels of honey pomelo fruits.

[0020] 4. In the post-production stage, the pomelo fruit is packaged and loaded into the packaging mechanism by the packaging loading mechanism. The packaging mechanism can package the pomelo fruit in different ways, which is conducive to selecting different packaging methods according to the value of the pomelo fruit or different selling methods. The same packaging mechanism can be used to complete different packaging methods, which is conducive to flexible packaging of the pomelo fruit by different packaging methods. The packaging of the pomelo fruit does not need to be completed by function or region, which is conducive to centralized processing, reducing the demand for space for pomelo fruit packaging, improving enterprise efficiency, and improving the efficiency of pomelo fruit sorting and packaging.

[0037] The packaging methods of the pomelo processing production line with flexible packaging options are as follows: Pre-production stage: After picking, different pre-treatment methods can be selected according to the length of time the pomelo fruit needs to be stored. If a longer storage time is required, the fruit needs to be cleaned, sterilized, preserved and other pre-treatments before primary sorting; if it does not need to be stored for a long time, the fruit can be directly sorted in the first level. The pre-treated pomelo fruit is conveyed by the pre-treatment conveyor line 16 to the defective fruit picking conveyor line 34 for manual sorting of defective fruit, and the pomelo fruit that does not require pre-treatment steps is conveyed by the fruit feeding conveyor line 36 to the defective fruit picking conveyor line 34 for manual sorting of defective fruit. After the defective fruits are removed, the remaining honey pomelo fruits pass through the first-level sorting table 24 and the first-level sorting line 25 in turn, and are sorted into four levels according to their weight, namely, oversized fruit, oversized fruit, qualified fruit one, and qualified fruit two. They fall into the empty frames on the oversized fruit frame conveyor line 26, the oversized fruit frame conveyor line 27, the qualified fruit one frame conveyor line 28, and the qualified fruit two frame conveyor line 29 below the belt under the flipping and tipping of the weighing bag on the first-level sorting line 25. Subsequently, the fruit frames containing honey pomelo fruits pass through the first receiving line 31, the second receiving line 32, and the third receiving line 33 respectively, and are stacked and stored in the fruit frame static area, so that the honey pomelo fruits lose some moisture and increase their sweetness.

[0038] Post-production stage: After standing, the honey pomelo fruit is transported to the packaging and loading mechanism, and the fruit frames are placed one by one on the fruit frame loading conveyor line 47. The tipping bucket loader 45 grabs the fruit frames and dumps them into the second fruit pool 46. The empty frames after dumping are manually placed on the empty frame recovery conveyor line 48 for stacking and recovery, and then transported to the empty frame placement area. The second lifting conveyor line 49 transports the honey pomelo fruit in the second fruit pool 46 to the first packaging conveyor line 50.

[0039] The pomelo fruit is transported by the first packaging conveyor line 50. The film sealing and cutting stations 51 on both sides of the first packaging conveyor line 50 are selectively used. The pomelo fruit can be directly transported to the rear by the first packaging conveyor line 50, or can be manually and semi-automatically covered with film and cut and then shrink-wrapped in a heat shrink chamber 52.

[0040] If the pomelo fruits delivered by the first packaging conveyor line 50 need to be packed in nets, the third packaging conveyor line 54 will receive the pomelo fruits and manually pack them in nets directly on the second packaging conveyor line 53 and the third packaging conveyor line 54. The pomelo fruits after being packed in nets will be manually placed on the second packaging conveyor line 53. If no net is needed, they will be directly transported to the rear by the second packaging conveyor line 53.

[0041] If the honey pomelo fruits delivered by the second packaging conveyor line 53 are to be directly bagged and sold, the fourth packaging conveyor line 56 receives the honey pomelo fruits and conveys them to the circular bagging line 63, where the honey pomelo fruits on the circular bagging line 63 are bagged manually. The circular bagging line 63 is in a ring shape and can well adapt to the efficiency of manual bagging. The honey pomelo fruits that cannot be bagged in time will continue to be conveyed for a week without falling.

[0042] If the pomelo fruits delivered by the second packaging conveyor line 53 are to be boxed and sold, the secondary sorting line 57 receives the pomelo fruits and delivers the pomelo fruits of different weights to the sixth packaging conveyor line 58 below it or to the sixth packaging conveyor line 59 according to the secondary sorting of the total amount of the pomelo fruits. The pomelo fruits delivered to the sixth packaging conveyor line 58 directly enter the weighting packaging line 61 for weighting and boxing. The pomelo fruits delivered to the sixth packaging conveyor line 59 continue to be delivered to the waxing conveyor line 60 to wax the surface of the pomelo fruits, and then the weighting packaging line 61 performs weighting and boxing.
