Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an egg drying device that uses high pressure to blow off water droplets attached to the surface of washed eggs.

(Prior Art) Water droplets adhere to the surface of chicken eggs that have been washed in an egg washing machine. The freshness of egg grains rapidly decreases because the pores of the egg grains are blocked by the adhesion of water. In order to deal with this problem, washed chicken eggs must be dried to remove moisture adhering to the surface of the eggs within as short a time as possible after washing. This depends on how quickly water droplets adhering to the surface of chicken eggs can be removed immediately after egg washing. This also affects the drying conditions of the next stage. In other words, if there is uneven adhesion of water on the egg surface, uneven drying will occur.

4 and 5 are a front view and a side view of a conventional water drop blowing device. The high-pressure air outlet 11 of the conventional device 10 for blowing off water droplets attached to the surface of eggs is installed on the egg washing section roller conveyor 12 immediately before the egg transfers from the egg washing section roller conveyor 12 to the drying section roller conveyor (not shown). It is provided in the upper part parallel to the egg washing part roller 13. Further, the high-pressure air outlet 11 is provided parallel to the egg washing section roller 13 and in a straight line shape. For this reason, eggs are usually transported in six rows.
4 passes directly under the high-pressure air outlet 11 while rotating around the long axis of the egg 14, an air curtain blown out from the high-pressure air outlet 11 parallel to the long axis of the egg 14 is blown onto the surface of the egg. .

Therefore, the air curtain covers the egg 14 on the surface of the egg.
The spraying starts on a line parallel to the long axis of the machine and ends as soon as the egg 14 passes over that line.

On the other hand, the water droplets attached to the eggs are blown out with air from the slits attached to the top.
A suction device (Japanese Patent Publication No. 60-33446) has been proposed in which the suction port provided at the bottom opens upward and sucks out water droplets. There was a problem that the equipment was expensive because it required a special cost. In addition, there was the problem that the suction port for sucking in the dirt adhering to the eggs along with the washing water became clogged. Further, the slit as the air outlet shown in the drawings is provided parallel to the long axis of the egg, similar to the conventional device.

(Problem that the invention aims to solve) Because the outer shape of a chicken egg is elliptical and one of its ends is more pointed than the other, conventional high-pressure air outlets are designed to connect the egg rotation axis directly above the egg. If you spray in parallel, the water droplets will wrap around the lower semicircle of the ellipse. In addition, since the circular curve of the tip of the chicken egg is steep, the area that the air curtain hits is narrow, and there is a problem in that the water droplets wrap around the egg more significantly than in other parts. This has the disadvantage that the water droplets adhering to the surface of the eggs are drained unevenly, resulting in incomplete drying in the drying section.

Therefore, the present invention lengthens the time that the air curtain hits the surface of each chicken egg without increasing the air volume, and also blows air from an outlet shaped like a side that intersects with the long axis of the egg. ,
This is an attempt to solve the above problems.

(Means for Solving the Problems) Therefore, the present invention was developed by arranging chicken eggs in multiple rows with their long axes horizontally, and cleaning them on the way to the conveyor of an egg washing and drying machine that rotates and conveys the eggs. A water droplet blowing device is provided for blowing off water droplets adhering to the chicken eggs with air, and a high-pressure air outlet of the water droplet blowing device is arranged to correspond to the row of the chicken eggs, and the water droplet blowing device is provided opposite to each chicken egg. The present invention provides a water droplet blowing device in which a high-pressure air outlet of the water droplet blowing device has a shape of an arbitrary side that intersects the long axis of the chicken egg at least at one point. More specifically, the high-pressure air outlet may have a one-sided shape that intersects the long axis of the egg at one point, or the high-pressure air outlet may have two points relative to the long axis of the egg. To provide a water droplet blowing device in the shape of two adjacent sides of a triangle intersecting at .

(Function) Since the present invention has the above-mentioned configuration, the water droplet blowing device installed on the upper part of the egg washing section roller conveyor immediately before transferring from the egg washing section roller conveyor to the drying section roller conveyor is, for example, a water droplet blowing device. If the high-pressure air outlet is formed on one side that intersects with the long axis of each egg, one end of the air curtain blown from the high-pressure air outlet first blows onto one tip of the egg. By the rotation of the egg wash roller and the egg, the egg moves to the other end while blowing away water droplets attached to the egg. At this time, the air curtain is in a state of intersecting the long axis of the egg, so the blown air goes around to the lower part of the egg and also sprays the water droplets that remain there. Therefore, from the time when one end of the air curtain intersects with the long axis of the egg until the other end leaves the long axis of the egg, the air curtain is spraying onto the egg, and at the same time, water droplets that are trying to wrap around the lower semicircular part of the egg are being blown onto the egg. It will also blow away.

In addition, if the high-pressure air outlet is shaped like two adjacent sides of a triangle, the air curtain blown out from the high-pressure air outlet first becomes the air curtain blown out from the vertices of the two sides of the triangle of the outlet. The water is then sprayed onto the surface of the washed chicken eggs, and as the egg washing section rollers and the eggs rotate, the air curtain gradually moves from the two sides of the triangle to blow away the water droplets adhering to the eggs. At this time, the air curtain gradually moves from the center of the egg to the tips on both sides, but even after the air curtain blown from the apex is removed from the egg, the air curtain blown from the other sides of the triangle is still washed. Spray on both ends of a chicken egg. Therefore, as in the case of the above-mentioned blower outlet formed on one side intersecting the long axis of the chicken egg, the air is sprayed from both sides of the rotating circumferential surface of the chicken egg, trying to reach the lower semicircular part of the egg. It has the ability to blow away water droplets.

(Example) An embodiment of the present invention will be described based on the drawings.

This embodiment is directed to a water droplet blowing device in which the high-pressure air outlet has the shape of two adjacent sides of a triangle intersecting the long axis of a chicken egg at two points.

Egg washing section roller conveyor 1 of egg washing and drying machine
The rotatable cylindrical rollers 3 each have six constrictions 6 so that the washed chicken eggs 4 are arranged in six rows facing the same direction. Further, the constriction 6 forms a gap 7 between adjacent cylindrical rollers 3. Therefore, the eggs 4 placed in the space 7 are transported while being rotated in the direction d opposite to the rotation of the cylindrical roller 3 in the direction of the arrow b as the eggs 4 are transported by the egg washing section roller conveyor 1. A water droplet blowing device 5 is provided on the upper part of the egg washing section roller conveyor 1 immediately before transferring from the known egg washing section roller conveyor 1 to the drying section roller conveyor (not shown). The high-pressure air outlets 2 of the water droplet blower 5 are positioned so that one high-pressure air outlet 2 faces each egg that is conveyed in six rows. More specifically, the triangular shape formed by the three points of the high-pressure air outlet is arranged so that one side longer than the long axis of the egg is parallel to the cylindrical roller 3, and the apex 8 is opposite to the side parallel to the cylindrical roller 3. is located upstream of the egg washing section roller conveyor 1 and located at the center of each egg. Further, the surface of the high-pressure air outlet 2 is provided so as to be horizontal to the egg washing section roller conveyor 1.

In FIG. 1, the washed eggs 4 are arranged in six rows and are conveyed in the direction of arrow a toward the high-pressure air outlet 2 of the water droplet blower 5 while rotating around the long axis of the ellipse that the eggs have. It will be done. The six high-pressure air outlets 2 are arranged so that the eggs 4 arranged in six rows face each other at the same time.
Eggs 4 are blown onto an air curtain blown out from high-pressure air outlet 2.

In FIG. 2, which is an enlarged perspective view of the water drop blowing device, the cylindrical roller 3 is rotatably attached, so that it rotates in the direction of arrow b as it is conveyed in the direction of arrow a. As the cylindrical roller 3 rotates in the direction of arrow b, the egg 4 placed in the gap 7 rotates in the direction of arrow d and moves directly under the high-pressure air outlet 2 while rotating. At this time, water droplets adhering to the washed eggs 4 are blown away by an air curtain blown out from the high-pressure air outlet 2.

Next, the process from the start to the end of spraying from the high-pressure air outlet 2 will be explained with reference to FIG. 3, which shows the movement of the air curtain 9 spraying onto the surface of the washed eggs 4 as the washed eggs 4 rotate. do.

First, the apex 9a of the air curtain 9 reaches the short axis of the egg 4, and moves along the short axis of the egg 4 as the egg 4 rotates. Since the air curtain 9 has a triangular shape, it is sprayed onto the surface of the egg 4 in such a way that it widens toward the end, and the air curtain 9 is sprayed onto the surface of the egg 4 while blowing off water droplets attached to the surface of the egg 4.
Move from to B and from B to C. Therefore, even after the apex 9a of the air curtain 9 is removed from the egg 4, the other side portions 9b on both sides are still spraying both ends of the washed egg, and the spray is applied from both sides of the rotating circumferential surface of the egg. shape, and can blow away water droplets that try to wrap around the lower semicircular part of the egg.

In this embodiment, one side of the triangular shape formed by the three points of the high-pressure air outlet 2, which is longer than the long axis of the chicken egg, is provided so as to be parallel to the cylindrical roller 3, but it does not necessarily have to be parallel. In addition, in this embodiment, the surface of the high-pressure air outlet 2 is provided so as to be horizontal with respect to the roller conveyor 1 of the egg washing section, but it does not necessarily have to be horizontal, and the same effect can be achieved even if the surface is positioned at an angle. Of course, it is effective.

In addition, as an embodiment in which the sides intersect at two points with the long axis of the chicken egg, there is one in which the high-pressure air outlet of the water droplet blower is U-shaped. This outlet also has the same structure and operation as in the previous embodiment, with the only difference being that the apex of the high-pressure air outlet is shaped like two adjacent sides of a triangle and has a gentle curve or an angular curve. can have.

Furthermore, as an example of a shape in which the side intersects at one point with the long axis of the egg, there is an example in which the high-pressure air outlet of the water droplet blower is formed with one side that intersects with the long axis of each egg. . In this case as well, the apex of the high-pressure air outlet, which is shaped like two adjacent sides of a triangle, is located at one of the tips of the egg, and the air curtain from the air outlet flows from one tip to the other tip. The only difference is that it moves toward the end, and the other effects are the same.

(Effect of the invention) As described above, the air curtain blown out from the high-pressure air outlet intersects with the long axis of the egg, and moves over the egg while blowing off attached water droplets due to the rotational movement of the egg.

This made it possible to blow away the water droplets that were about to wrap around the lower semicircular portion of the egg and adhere to the surface of the egg again. In addition, the time that the air curtain was in contact with the surface of each egg was increased, and the air curtain was able to be applied efficiently. As a result, water droplets adhering to the surface of washed chicken eggs are evenly blown away, reducing the time and space required for the drying process without increasing the air volume of conventional water drop blowing devices.
