Core-removing and peeling machine for litchi fruits

Abstract

The invention provides a core-removing and peeling machine for litchi fruits which has a simple structure and can obtain high-quality pulp. The core-removing and peeling machine for the litchi fruits comprises a drive device and a core-removing device and a graduated disk which are respectively connected with the drive device; material clamps for clamping the litchi fruits are arranged on the graduated disk; the core-removing device comprises a core-poking knife which can reciprocate left and right and a core-poking rod which is used for removing cores; the core-removing and peeling machine for the litchi fruits further comprises a peel annularly-cutting device and a scraping device; the peel annularly-cutting device comprises a knife rest which is connected with the drive device and an annularly-cutting knife which is fixed on the knife rest and can rotate around one litchi fruit so as to cut the litchi fruit into an upper half peel and a lower half peel; the scraping device is arranged above the core-poking knife and comprises two scraping plates which are connected with the drive device; and a position detecting and controlling device which can detect the positions of the litchi fruits and control the scraping plates to move up and down is respectively arranged on one side of each scraping plate close to the graduated disk. The core-removing and peeling machine for the litchi fruits has no need of repeatedly squeezing pulps, so that the juice loss is little and the pulps are complete and are of lantern shapes.

Description

technical field [0001] The invention relates to an agricultural product processing device, in particular to a litchi removing core and peeling machine. Background technique [0002] Litchi is a tropical fruit with strong seasonality and short and concentrated ripening time. The picked lychee is easy to change color and taste, it is difficult to preserve for a long time, and the preservation cost is high. At present, the integrated denucleation and peeling technology of litchi deep processing is not yet mature. In the deep processing of litchi, it is necessary to manually complete the denuclearization and peeling process, which results in poor sanitation, low efficiency, high labor costs, and limited scale production. [0003] Chinese patent ZL 201020141853.4 discloses a lantern-shaped lychee pulp harvesting machine, including a sorting mechanism, a feeding mechanism, a coring mechanism, a top-core mechanism and a peeling mechanism. Although the patent integrates the pitting...

AI Technical Summary

Problems solved by technology

Although the patent integrates the pitting and peeling processes, the structure of the patent is complex, and the pulp needs to be repeatedly squeezed during the processing process, resulting in a large loss of juice, and the pulp is easily broken, and the pulp and peel are not easy to separate. Not high, low production efficiency, difficult to meet the current development needs of litchi industry
