Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water drop blowing device for chicken eggs, which blows off water drops adhering to the surface of washed eggs by high pressure air.

[0002]

2. Description of the Related Art Water droplets are attached to the surface of chicken eggs washed by an egg washing machine. Due to the adhesion of water, the porosity of the eggshell is blocked, resulting in a rapid decrease in freshness. In order to deal with this, the eggs that have been washed should be dried by removing the water adhering to the surface of the eggs within as short a time as possible after washing the eggs. For that purpose, it depends on how quickly water drops adhering to the surface of the chicken egg can be drained immediately after washing the eggs. This also affects the dryness of the next stage. That is, if there is uneven adhesion of water on the surface of the egg, uneven drying will occur. Therefore, after water drops adhering to the eggs after washing the eggs are quickly blown off with air, a large number of brushes are rotated and directly applied to the surface of the eggs to be brushed to speed up the drying as much as possible. The applicant has filed in Japanese Patent Application No. 3-42567.
We devised a device that crosses the high-pressure air outlet on one side with the long axis of the egg and reciprocates in the long axis of the egg in a width wider than the long axis of the egg.

[Problems to be Solved by the Invention] Japanese Patent Application No. 3-42567
In this device, the moving distance of the high-pressure air outlet on one side is larger than the long axis length of the average chicken egg, so it was necessary to make the water drop blowing device large-scale. The present invention rolls and conveys eggs, and the shape of the drum roller is made into a smooth drum shape so that the flow of high-pressure air is made smooth and the movement distance of high-pressure air on one side is shorter than the long axis of the average egg. It has achieved its purpose. This simplifies the device and eliminates the need for brushing for drying after removing water droplets, thus eliminating the egg transfer path required for brushing.
It is a shortened chicken egg conveyor. Further, the present invention makes it possible to provide a clean and safe chicken egg to the market by eliminating any adhesion of bacteria to the washed chicken egg, which has been considered impossible in the past, due to brush contact.

[0004]

[Means for Solving the Problems] Therefore, according to the present invention, the long axis of the egg is arranged in a line in a plurality of rows in an orderly manner, and the egg is washed and dried while the conveyor of the egg washing and drying machine conveys the egg.
A high-pressure air outlet that blows off the water droplets attached to the washed eggs with air, has a shape of one side extending intersecting at a right angle to the long axis of the egg, and conveys the egg and blows air on the long axis. The present invention provides a water droplet blowing device which is provided so as to swing while maintaining a state of intersecting at a substantially right angle and reciprocates centering right above the body of the egg. More specifically, it also includes a water droplet blow-off device in which the high-pressure air outlet has a shape of one side extending intersecting with the long axis of the egg at 45 ° to 90 °.

Since the present invention has the above-described structure, when the high-pressure air outlet of the water droplet blowing device is formed by one side intersecting at a right angle with the long axis of each egg, the high pressure is high. One side of the air curtain blown out from the air outlet is first blown onto the upper surface of the rolling egg, at which time large water droplets are blown away, and the remaining water content is the pressure of the air and the swinging of the outlet, as well as the egg. The water on the entire circumference is driven to both ends of the egg by the rolling of the egg, and then jet air generated between the smooth curved surface of the egg transport roller and the curved surface of the egg causes the water to drop below the middle part of the hourglass roller and the hourglass roller. Is blown away, so the blown air also circulates to the bottom of the egg and blows off any water droplets that remain there. Therefore, while one side of the air curtain crosses the long axis of the egg until it separates from the long axis of the egg, it is sprayed onto the egg, and at the same time, water drops that try to wrap around the lower half-circle of the egg drop the egg. It will be blown off by the high pressure air that wraps around the smooth curved surface of the moving hourglass roller (Fig. 2).

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. The present embodiment is directed to a water droplet blow-off device having a one-sided shape in which a high-pressure air outlet crosses a long axis of a chicken egg at a right angle.

As shown in FIG. 1, the hen's egg 1 after washing is indicated by an arrow a.
The roller conveyor 2 for transferring in the direction is composed of rotatable drum-shaped rollers 3, and the central portions are thin so that the washed eggs 1 are aligned in the same direction in an orderly manner. The roller 3 forms a gap 4. Therefore, the egg 1 placed in the gap 4 is conveyed while being rotated in the direction d opposite to the rotation of the hourglass roller 3 in the direction of the arrow b as the roller conveyor 2 is conveyed. A high-pressure air outlet 5 is provided on the upper part of the roller conveyor 2, and one high-pressure air outlet 5 faces one row of high-pressure air from the tip 6 of the outlet and is conveyed in a row. To position. For more details,
The egg 1 is crossed at a right angle to the long axis, and one side of the high-pressure air outlet 5 is positioned parallel to the arrow a direction which is the transport direction of the roller conveyor 2. Therefore, the high-pressure air outlet 5 intersects the long axes of a plurality of eggs in the same row. In FIG. 1, the high pressure air outlets 5 are shown in a row. The tip 6 of the outlet of the high-pressure air outlet 5 is provided so as to be horizontal with respect to the roller conveyor 2.

The curtain-shaped high-pressure air blown out from the blow-out port 6 of the high-pressure air blow-out port 5 of the water-drop blowing device thus constructed acts on the chicken egg 1 as follows. In FIG. 1, the washed eggs 1 are arranged in a line and are conveyed in the direction of arrow a below the high pressure air outlet 5 of the water droplet blowing device while rotating about the long axis of the ellipse of the eggs 1. The high-pressure air outlets 5 intersect the major axes of the eggs 1 arranged in a line at a right angle, and curtain-like air blown out from the high-pressure air outlets 5 is blown onto the eggs 1.

Since the hourglass-shaped roller 3 is rotatably attached, it rolls on the lower fixing plate and rotates in the direction of arrow b as it is conveyed in the direction of arrow a. Along with the rotation of the hourglass roller 3 in the direction of arrow b, the egg 1 placed in the gap 4 moves in the direction of arrow d while rotating below the high-pressure air outlet 5. At this time, the water drops adhering to the washed eggs 1 are blown off by the curtain-shaped air blown out from the high-pressure air outlet 5.

Next, from the start of blowing from the high-pressure air outlet 5 to the end of blowing, the curtain-like air oscillating state blown onto the surface of the egg 1 along with the rotational movement of the washed egg 1 is shown in FIG. Will be explained. First chicken egg 1
The curtain-shaped air near the blunt end (A of FIG. 3) gradually moves with the movement of the high-pressure air outlet 5 to the egg 1
Move to the center of the (Fig. 3B). Then, by moving the high-pressure air outlet 5, the curtain-shaped air moves to the egg 1.
It moves away from the blunt end to the sharp end (C in FIG. 3), and then reciprocates toward the center of the egg 1 again.

In this way, the water droplets adhering to the surface of the egg 1 are blown away, and the surface of the egg 1 moves from A to B, from B to C, again from C to B, and from B to A,
By the transfer of the egg 1 in the direction of the arrow a, the curtain-shaped air keeps the egg 1 flowing until the egg 1 comes off the high pressure air outlet 5.
It makes multiple round trips at a right angle to the long axis.

In this embodiment, since the reciprocating swing width of the curtain-shaped air is set to a width close to the major axis of the egg 1, one high-pressure air outlet 5 is provided for each egg. By increasing the length, one high-pressure air outlet 5
Will be moved to the information of the next adjacent egg, in which case the high-pressure air outlets will be provided in a number smaller than the number of rows of eggs.

FIGS. 1 to 5 show an embodiment in which the curtain-shaped air has a shape of a side intersecting with the long axis of the egg at a right angle, and the crossing angle of the curtain-shaped air with respect to the egg 1 is shown. Is substantially in the range of about 45 degrees, the same effect can be obtained.

Further, the width of the reciprocating motion does not necessarily need to be the width of the long axis of the egg, and since the air wraps around a smooth curved surface close to the spherical surface of the egg, it is approximately 6 of the long axis of the egg.
The purpose can be achieved with a reciprocating width of about 70% to 70%.

[0015]

As described above, the high pressure air outlet 5
The curtain-shaped air blown out of the chicken crosses the long axis of the egg at a right angle, and the rotational movement of the egg causes the water droplets adhering to it to be blown off and reciprocally swings on the long axis of the egg. Therefore, high-pressure air is blown multiple times around the entire body of one egg.
It was possible to blow away the water droplets that went around to the lower hemisphere of the egg and tried to adhere to the surface of the egg 1 again. by this,
The brushing after blowing off the surface water droplets, which was indispensable in the conventional device, is unnecessary, and at the same time, the egg transfer path for that is also unnecessary. This also shortened the egg transfer conveyor, shortening the drying process time and saving space. In addition, it became possible to completely prevent the attachment of bacteria due to brush contact after washing and to ship hygienic eggs to the market.
