Description

Technical Field

[0001] This invention belongs to the field of pulverization technology, specifically relating to a jackfruit polysaccharide extraction device and extraction method. Background Technology

[0002] Jackfruit is an evergreen tree belonging to the genus *Jackfruit* in the family Moraceae. Because its fruit hangs on the tree like a pineapple, it is also called tree jackfruit. Its outer shell has many spiky protrusions of varying sizes, and is green or yellowish-green in color. It is hard in texture. During the extraction of jackfruit polysaccharides, the pulp often needs to be crushed. Current methods involve manually removing the outer shell and then crushing the pulp in a grinder to obtain smaller particles, which facilitates subsequent polysaccharide extraction. However, manually removing the outer shell is inefficient, and the process of feeding the removed pulp into specialized crushing equipment is cumbersome. Summary of the Invention

[0003] The purpose of this invention is to provide a jackfruit polysaccharide extraction device and extraction method, which solves the problems mentioned in the background art by setting up an automatic set of equipment for shelling, core removal and crushing.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a jackfruit polysaccharide extraction device, comprising a support, a cutting device mounted on the support, a peeling mechanism mounted on one side of the cutting device, a turntable mounted on one side of the peeling mechanism, a plurality of fruit tubes mounted on the turntable, each fruit tube comprising a rotatably mounted arc-shaped plate, the arc-shaped plate being connected to a push-pull plate via a connecting column, the push-pull plate having a push-pull groove and a guide groove, the connecting column also being connected to the turntable via a tension spring; a crushing linkage mechanism is also mounted on the support, the crushing linkage mechanism being driven by a drive mechanism, the crushing linkage mechanism comprising a peeling push rod, a core tube, and a crushing push rod, one end of the crushing push rod being connected to a crushing mechanism, the crushing mechanism comprising a crushing motor and crushing blades, the crushing push rod having blades connected to a rotating rod inside, one end of the blades connected to the rotating rod being connected to the blades, the other end being driven and connected to the crushing motor; the crushing push rod is also connected to a push-pull rod, the push-pull rod having push-pull protrusions.

When the crushing push rod moves to one side of the turntable, the push-pull protrusion moves along the guide groove and moves to the end of the guide groove. The push-pull protrusion pops out and enters the push-pull groove. When the crushing push rod returns, the push-pull protrusion acts on the edge of the push-pull groove to move the push-pull plate and open the arc plate outward.

[0008] Preferably, the crushing linkage mechanism further includes a guide rod, a movable plate, and a connecting rod. The guide rod is mounted on the bracket, the movable plate is movably mounted on the guide rod, the connecting rod connects to the movable plate, and the peeling push rod, the core tube, and the crushing push rod are all mounted on the movable plate.

[0013] A method for extracting polysaccharides from jackfruit includes the following steps:

[0014] The jackfruit is placed into a cutting device to be cut into sections, and the jackfruit sections are then fed into a peeling mechanism.

[0015] The peeling pusher pushes the jackfruit segments into the peeling tube to separate the peel from the flesh, and the flesh continues to be pushed into the tube.

[0016] The rotating turntable moves the fruit tube containing the pulp to one side of the core tube, and the core tube moves to remove the pulp from the fruit core;

[0017] The rotating turntable moves the cored fruit pulp to the side of the crushing pusher. The crushing pusher moves forward and sends the crushing mechanism into the fruit cylinder, crushing the cored fruit pulp inside the fruit cylinder.

[0018] Polysaccharides were extracted from the crushed fruit pulp using an acid-base method.

[0019] The technical effects and advantages of this invention are as follows: 1. It integrates functions such as shelling, core removal and crushing, which greatly reduces the manual labor intensity of the crushing stage in the extraction of jackfruit polysaccharides and improves efficiency.

[0020] 2. After crushing, the powder can be directly collected inside the turntable, which is convenient for collection. Moreover, the arc-shaped plate of the fruit cylinder on the turntable can be switched on and off in conjunction with the crushing push rod, without the need for an additional power supply for the arc-shaped plate switch, making it highly practical.
