Description

[Detailed Description of the Invention] A. Purpose of the Invention A. Field of Industrial Use Hard-shelled seeds such as ginkgo nuts and pine nuts have their shells removed and the fruits are processed and used in cooking, or as food for sweets and sake appetizers. It is processed and sold.

B. Conventional technology A pliers-type device is used to split the shells of ginkgo and pine nuts, such as Utility Model No. 13-16535, Utility Model No. 16535, Utility Model No.
There are No. 40-2280 or Utility Model No. 27-2679, etc., but 1
The seeds are picked out one by one with pliers, the shell is split open, and the fruit is extracted. With such inefficiency, it is not possible to meet the demands that are required in large quantities. Recently, there has been a method in which a large amount of seeds are placed in a hopper, and a vibrator is used to shake the seeds from the hopper onto a seed receiving plate, arranging the seeds in a line, and placing the seeds between upper and lower rollers to crush the shells, such as Utility Model No. 52-17515. Although this device removes seeds more efficiently than before, it is complicated to adjust the rollers for crushing the shells, and if the shells are crushed at the same time, the fruit may be crushed or damaged at the same time, making it difficult to operate the machine. It is inconvenient to operate and cannot meet current demand because the seeds are lined up one by one and the shells are crushed with a roller.

C. Problems to be solved by the invention The conventional method of crushing shells using pliers is inefficient and cannot meet large-scale demands. The shell crushing method using rollers is more efficient than using pliers, but since the seeds vary in size, large seeds may be crushed too much and damage the fruit, and small seeds may be crushed without being crushed by the rollers. It is more inconvenient to leave. The present invention aims to solve these inconveniences and provide a large quantity of unblemished seeds.

B. Structure of the Invention A. Means for Solving the Problem (a) A strong pipe such as a stainless steel pipe having an inner diameter slightly larger than the thickness of the seeds to be crushed is compressed into one end of the injection pipe 1 cut to an appropriate length. A compressed air regulating valve 3 (explained in FIG. 3) is fixed to the injection pipe 1 a little to the left of the screw connecting to the air tank 2, so that the air pressure inside the injection pipe 1 can be adjusted with a handle 4.

(b) On the left side of the compressed air adjustment valve 3, open the hopper 5.
The seed ejection tube 7 is positioned under the outlet of the seed receiving plate 6 equipped with a vibrator connected to the lower side of the seed discharge tube 7.
Incline the lower part to the left side and insert and fix into the injection pipe 1 from above. In this case, the seed discharge tube 7
The tip of the cut is cut diagonally so that the tip of the cut protrudes slightly to the left inside the injection pipe 1, and the cut end other than the tip is flush with the inner wall of the injection pipe 1, and the seeds are removed from the opening of the seed discharge port 7. so that it is discharged to the left side. With this configuration, the compressed air collides with the protruding part of the seed discharge pipe 7, and the compressed air obtains a weak spiral rotation, and the seeds are also rotated by the spiral rotation of the air, and the injection pipe 1 is rotated. move rapidly to the left.

(c) The shell crushing chamber 8 is a cylinder slightly larger than the injection pipe 1, and one end is closed and the left end of the injection pipe 1 is inserted into the center and protruded and fixed.

The other end of the shell crushing chamber 8 is open, and the opening is covered entirely with a cover plate 9, and a lid 10 with a circular hollowed out center from the outside is screwed onto the opening so as to press the cover plate 9 against the opening. Fix it.

The backing plate 9 has an appropriate thickness, has mesh-like or granular uneven surfaces densely formed on both sides, has a small hole 11 with a diameter of about 1 mm in the center, and has a small hole 11 in the center immediately before the inner side of the backing plate 9. An opening 12 with an appropriate width and length required for the crushed shells to fall is provided below the cylinder of the shell crushing chamber 8, and the distance between the contact plate 9 and the tip of the injection pipe 1 is 3.
A shell crushing chamber 8 is formed to have a size of approximately cm.

(d) Install an appropriate number of injection pipes 1 having the above structure in line under the hopper 5, and fix them to the body frame;
The seed receiving plate 6 is connected to the seed discharge pipe 7 by a flexible resin pipe, and the left end of the injection pipe 1 is connected to the compressed air tank 2.

(b) Regarding functions and examples, put hard-shelled seeds into the hopper 5, operate the vibrator to guide the seeds to the seed receiving plate 6, put air into the compressed air tank 2, turn the valve handle 4 to open the valve, and the air will be released. The seeds quickly move toward the left and right sides of the injection pipe 1, pushing the seeds that have fallen from the seed discharge tube 7, and at the left end of the injection pipe 1, the seeds collide with the air at right angles to the plate 9, and the impact causes the seed shells to break off. The seeds and shells are crushed and fall below the opening 12 at the bottom of the shell crushing chamber 8. In this case, since a small hole 11 is provided in the center of the backing plate 9, the central part of the air pressure tends to pass through the small hole 11 and move straight, so the seeds are pushed by this force and collide with the backing plate 9 at right angles. Since the surface of the plate 9 is provided with a mesh-like or granular uneven surface, the seeds collide accurately with the plate 9 at right angles without sliding sideways when colliding with the plate 9, resulting in a good shell crushing effect. be.

As a result of the experiment, the shell is 100% regardless of the size of the seed.
It's completely crushed. The opening 12 provided at the bottom of the shell crushing chamber 8 together with the crushed shells and the strong wind force
If the fruit is hard, such as a ginkgo nut, it may be necessary to have a hard board to hold it, but if the fruit is very soft, such as a pine nut, it may be damaged when it falls. Therefore, it is appropriate to use a small mesh net or cloth to catch the wind underneath, but it is thought that it is better to use a net than cloth, especially since the net is suitable for dispersing the wind force.

C. Effects of the invention A: Hard-shelled seeds can be completely crushed 100% regardless of their size.

(b) If the length of the injection pipe is approximately 1 mm, it is recognized that the crushing effect is sufficient, so it is possible to downsize the machine.

C. It is highly economical because the injection pipe can be used depending on the amount of crushed seeds by operating the valve handle.

D. Production costs are low.

It has the following advantages.
