Description

[Detailed Description of the Invention] (a) Industrial Application Field This invention relates to a method for extracting seeds from plums, etc., without damaging the appearance.

(b) Conventional technology Conventionally, plums are pitted by pre-treatment to improve the separation of the seeds, then by making a vertical slit from the stem and squeezing the seeds to push out the seeds, or by splitting them into two or four parts. The seeds are then removed.

(c) Problems that the invention aims to solve However, plums that have been pitted using the conventional method are severely damaged in appearance and lose their commercial value as plums. let me in,
Currently, plum meat is only used by wrapping it in something else so that it is not visible.

This invention eliminates the above drawbacks by simple means and
The purpose is to provide a method for extracting seeds without damaging the appearance of plums.

(d) Measures to solve the problem A hole is made with a cylindrical knife A from the stem side of a plum that has been pre-treated using the conventional method to improve seed separation.
A hole is made from the opposite side with a cylindrical knife B, and a plum seed C is supported with knives A and B to give rotation to the plum.

Next, by manually stopping the rotation of the plum meat D, only the plum seeds C are supported by the cutlery A and B and rotated, and the seeds C
The plum meat D attached to it comes off.

In this state, the seeds C are taken out from the plum meat D by sliding the plum meat D toward the knife B side.
By pulling the knob E in the direction of the arrow, the seed C will fall off the knives A and B, and by pulling the knob E further, the plum meat D will fall from the knife B.

Depending on the size of plums, the shapes of the seeds C vary widely, but by matching the varieties of plums and the size classes S, M, and L of the plums, the diameter of the knife A can be made constant. Change knife A depending on the size and type of knife.

The shape of plum seed C is as shown in Figure 2 when shown in the C′-C″ cross section, and the diameters A and B are different, and the parts 1 and 2 on both sides of the seed are acute angles. If you push it out without rotating it, the plum flesh will break at both ends 1 and 2 of the seed, but if you give Seed C rotation, you can take out Seed C without breaking the plum flesh even through a hole that is about 3 mm smaller than the diameter of the seed. In the above, the seeds of plums have been explained, but the present invention can be used not only for removing seeds of plums but also of other fruits.

(E) Action Due to the rotation of the seeds and the elasticity of the pulp, the seeds can be removed with the diameter of the cutter A smaller than the diameter of the seeds C.

(f) Effects of the invention The seeds can be removed without damaging the appearance of the fruit.

Claims (1)

[Claims] 1. Drill a hole with a rotating cylindrical knife from the calyx of the fruit, which has been pretreated to improve seed separation, and from the opposite direction, and fix the pulp while supporting the fruit seeds from both sides and giving them rotation. After separating the pulp and seeds, the seeds are pushed out while rotating, and the seeds are removed without damaging the appearance of the fruit.
