Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ginkgo flesh removing device suitable for use in a collection / shipping site where a large amount of ginkgo is collected and shipped, a production farmer or the like.

[0002]

2. Description of the Related Art In Ginkgo G, as shown in FIG. 10, a fruit a wrapped with a thin skin b is covered with a hard outer shell c.
The outer side of the is covered with a flesh d having a slight thickness (note that, as shown in FIG. 10, the outer side of the outer shell c has a fruit stem, but in this specification, it is referred to as “flesh”. It also includes the fruit pruning, and the explanation of the pruning is omitted). And
The shipping of this ginkgo G is performed after removing the pulp d.

Conventionally, this pulp removing work has been performed by a so-called agitation tank in which the blade is rotated at the bottom of a cylindrical container. In this conventional stirring tank, the flesh is separated from the outer shell containing the fruit only by stirring the ginkgo in the tank, and the operator manually removes the flesh from the stirring tank. Only the separated outer shell (the outer shell containing the fruit. The same applies hereinafter) was taken out.

[0004]

However, since the stirring tank which is the conventional pulp removing device is intended to separate the pulp from the outer shell only by stirring the ginkgo as described above, It has a drawback that it takes a considerable amount of time for the separation, the separation speed is slow, and that the outer shell has a large amount of flesh attached to it without separation. Furthermore, since the sorting work that takes out only the outer shell from which the pulp has been separated from the stirring tank relies on the manual work of the operator, this sorting work also requires a considerable amount of time, and the efficiency of the pulp removal work is low. In addition to the above-mentioned drawbacks, the worker often causes rashes and inflammations when the worker touches the flesh of the ginkgo at the time of this sorting work and the like, which is unhygienic.

The present invention solves the above-mentioned conventional drawbacks and can reliably and automatically separate and separate the flesh and outer shell of the ginkgo flesh, and the flesh removal work of the ginkgo is efficiently and hygienically performed. The purpose is to provide a ginkgo flesh removing device.

[0006]

In order to solve the above-mentioned problems, the ginkgo flesh removing device of the present invention allows the gingko flesh to pass through the inside of the tubular body with respect to the inner peripheral surface of the tubular body. Disc-shaped bottom plate with a large number of holes of a predetermined shape formed in a predetermined arrangement, and above the bottom plate, rotating horizontally to stir the ginkgo on the bottom plate. Meanwhile, a stirring blade for crushing the flesh and a scraper provided below the bottom plate to rotate horizontally and droop the flesh of ginkgo hung from the hole in the bottom plate are provided.

[0007]

According to the present invention configured as described above, the harvested ginkgo is collected in a predetermined amount and supplied into the tubular body. The ginkgo fed into the tubular body is agitated by a stirring blade that rotates in a horizontal direction above the bottom plate having holes, and the ginkgo collides with each other (rubbing), friction (rubbing), and the edge of the ginkgo and the bottom plate. The flesh is crushed by the collision and friction of. The crushed flesh is drooped and discharged downward sequentially through the holes in the disc-shaped bottom plate and the gap between the outer peripheral edge of the bottom plate and the inner peripheral surface of the cylindrical body during rotation of the rotating stirring blade, and the flesh and outer shell are separated. It will be separated and sorted. During this drooping discharge, the pulp that hangs down from the hole in the bottom plate is scraped out by the rotating scraper provided below the bottom plate, so that the pulp and the outer shell are separated and separated at high speed. The holes in the bottom plate and the gaps outside the outer peripheral edge of the bottom plate are sized to allow only the crushed pulp to pass, and the ginkgo supplied is crushed by rotating the stirring blade for a predetermined time. With
Only the crushed pulp is discharged downward from the holes and gaps, and only the outer shell remains on the bottom plate.
