Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to an apparatus for producing aged eggs, and more particularly to a dry egg cooking apparatus for producing aged eggs, that is, whole-boiled and soft-boiled eggs.

(b) Prior art As is well known, in order to produce aged eggs, eggs are heated in water. It is necessary to adjust the heating temperature and heating time.

Conventionally, when a boiled egg is cut into rounds, in order to produce mature eggs that have a good appearance with the yolk located in the center of the egg white, it is necessary to rotate the egg appropriately during heating to heat it evenly. . Production of such aged eggs is easy, for example, when making small quantities of such aged eggs, as the eggs can be rotated appropriately in boiling water. When making aged eggs, it is difficult to rotate the eggs in boiling water without damaging them in any way. It is not possible to obtain a ripened egg in which the is located in the center. Moreover, when producing aged eggs using such an egg heating method, a batch method must be used because of the egg heating method.
Therefore, in the production of aged eggs, conventional methods require handling of large containers containing boiling water.
The problem was that it was always dangerous for workers, and the eggs had to be reheated each time to avoid rapid heating, resulting in high fuel costs. Moreover, the shells of the eggs tend to crack during heating, and even if a frame or the like is formed to fix the position of the eggs, it is a major effort, and it is difficult to rotate the eggs, causing the yolks to become uneven. There was a problem.

(c) Structure and operation of the invention Therefore, the purpose of the invention is to eliminate the above-mentioned problems by developing a complete system that can continuously produce aged eggs in large quantities without heating them in water as in the conventional case. The present invention provides a novel aged egg heating production device.

The present invention consists of a housing that has an inlet opening and an outlet opening in opposing side walls, and an exhaust port with an exhaust blower formed in the ceiling, and a housing that extends in parallel to a drive sprocket and a guide sprocket, respectively. two parallel rows, at least a part of which is formed in a circulation path having an upper runway and a lower runway disposed through the inlet opening of the housing, the interior of the housing and the outlet opening of the housing. The end portions of the endless chain and the two rows of parallel endless chains are pivotally supported at mutually corresponding positions, and each of the two rows of parallel endless chains has a shaft with a dimension slightly larger than the size of an egg at its outer circumferential surface. , and a plurality of cylindrical members each having egg-supporting grooves with an arcuate cross section formed in the circumferential direction are arranged in such a manner that the grooves of adjacent cylindrical members correspond to each other. A tube for supporting the cylindrical member is provided at a position in contact with the lower surface of the end of each cylindrical member below the row of cylindrical members on the upper traveling path of the two rows of parallel endless chains. A ripening method comprising: a rail member; and an infrared or far-infrared radiator provided in the housing above the row of cylindrical members on the upper running path of the two parallel endless chains. Located in continuous egg production equipment.

The reason why infrared rays or far infrared rays are used in this invention is that infrared rays or far infrared rays have excellent permeability to eggshells, so it is possible to directly heat the egg yolk inside the eggshell and heat it efficiently in an extremely short time. It is possible to do so. The light having a wavelength within the infrared or far infrared wavelength range used is 1 μm to 25 μm, and in particular, the water absorption wavelength band and protein absorption wavelength include infrared and/or far infrared rays within the wavelength range of 2.5 to 10 μm. This is preferred because it covers the entire range.

Therefore, the infrared emitter or far-infrared emitter used in the present invention is one that emits light having a wavelength within the infrared or far-infrared wavelength range, particularly from 1 μm to 25 μm, particularly from 2.5 μm to 10 μm. It emits light within the wavelength range of .

Furthermore, in the present invention, the amount of heating of the egg can be easily adjusted by adjusting the distance between the infrared ray emitter or the far infrared ray emitter and the egg.
Thus, in order to adjust the intensity of the infrared rays or far infrared rays, for example, the infrared rays or far infrared rays emitter is preferably formed to be movable relative to the egg;
Further, it is preferable that the infrared heater, far infrared heater, etc. be formed so that the voltage can be adjusted.

In the aged egg production apparatus according to the present invention, the eggs are supported by a rotary transfer cylindrical member in order to constantly rotate the eggs without contacting each other. In this case, in order to stably support the egg at a predetermined position on each of the parallel cylindrical members, a groove is formed which extends over the entire circumferential direction of the cylindrical member and matches the contour of the egg.

The size of the groove is such that the egg does not swing and break within the groove, and is preferably a size that is slightly larger than the egg size or smaller.

The present invention uses infrared rays and/or far infrared rays to heat eggs, thereby making it possible to obtain boiled eggs similar to conventional methods in a short time. This is because when the far infrared rays are irradiated, the far infrared rays can reach the center of the egg through the egg shell, thereby heating not only the outer surface of the egg but also the center.
On the other hand, when thermal radiation with a wavelength smaller than infrared rays is used, the surface of the egg is heated excessively compared to the contents, and the heat accumulates around the eggshell, which tends to generate water vapor. The eggshell is easily destroyed, and it takes a long time to obtain a ripened egg, making it unsuitable for use.

On the other hand, in the present invention, the eggshell is heated by the infrared rays, and the pores of the eggshell and inner coating are fused and become airtight, thereby avoiding contamination.

In the present invention, an opening equipped with an exhaust blower is formed in the ceiling of the housing in order to keep the temperature inside the housing constant.

The present invention will now be described in more detail with reference to the accompanying drawings, in which: FIG. 1 is a schematic diagram of a semiconductor device according to an embodiment of the present invention;

It is composed of a beam member 5 attached between the tops of two column members 4 located on both sides of the direction. As shown, hydraulically actuated telescoping legs 6 and wheels 7 are mounted at appropriate locations on the bottom of the frame 3. When the aged egg producing apparatus 1 is to be moved, the legs 6 are retracted, and at this time the aged egg producing apparatus 1 is supported by the wheels 7, thereby holding the aged egg producing apparatus 1 in a predetermined location. It can be moved up to. After the aged egg manufacturing device 1 has been moved to a predetermined location, the legs 6 are extended as shown, and the wheels 7 are released from the floor, thereby stabilizing the aged egg manufacturing device 1 in the predetermined location. It will be installed. A heating area is provided in the upper part of the support frame 2 of the aged egg production device 1, and a heating housing 8 is provided in this heating area.
The heating housing 8 is composed of a plurality of rectangular frame bodies 9, which are supported on the beam members 5 of the support frame 2 and arranged along the longitudinal direction of the support frame 2. Panels 10 that can be opened and closed are provided on both sides of each frame 9, and a fixed panel 11 is provided on the top surface of each frame 9, thereby forming a tunnel-shaped heating housing 8 with both longitudinal ends open. Ru. A thermal radiation source 12 is provided within each frame 9. The thermal radiation source 12 is mainly 1
It is composed of a far-infrared radiator 13 that radiates sound wave light in a wavelength range of ~25 μm, a reflector 14 provided above the far-infrared radiator 13, and a support 15 that supports both of these elements. As shown, the support 15 is suspended from the top inside each frame 9 so as to be movable up and down, for example by a chain 16. Although not shown in detail, the support 15 can be moved up and down by pulling up or down the chain 16 from the outside. In order to stably move the support body 15 up and down, a guide rod 17 is suspended from the top of each frame.
7 passes through a guide hole 18 formed in the support body 15. An exhaust blower 19 is provided on the upper fixed panel 11 of the frame 9, which allows the heating housing 8
The internal atmospheric temperature is regulated.

The aged egg manufacturing apparatus 1 also includes a conveying means 20 for rotating the egg and passing it through the heating area, that is, the heating housing 8. This conveyance means 2
0 is composed of a pair of endless chain elements 21 and a large number of parallel roller members 22 rotatably stretched between the endless chain elements 21 to support eggs. A pair of endless chain elements 21 are supported by a pair of gears 23 and 24 that are respectively pivotally supported at both ends of both beams 5 of the support frame 2, and at a location below the beam 5 of the support frame 2 and above the frame 3. It spans three pairs of gears 25, 26, and 27 that are pivotally supported between both sides of the frame 2. Note that in FIGS. 1a and 1b, only one of the pair of gears 23, 24, 25, 26 and 27 is shown.

As shown in FIG. 1, the frame body 3 of the support frame 2
In the leftmost part of , there is a pair of endless chain elements 2
A drive wheel 28 coaxial with a drive gear 23 for driving the motor 1 is connected to a prime mover, that is, an electric motor 30 via a speed reducer 28' and a drive belt 29.
A pair of drive gears 23 are connected via this drive belt 29.
is rotationally driven, and as a result, the pair of endless chain elements 21 are driven, for example, clockwise in FIG. That is, it is passed through the heating housing 8.

The parallel roller section 22 includes a pipe 33 made of, for example, steel, a plurality of roller pieces 34 made of, for example, aluminum passed over the pipe 33, and a heat-resistant urethane rubber layer 35, for example, coated on these roller pieces 34. It consists of The roller pieces 34 are preferably connected by a mortise and tenon joint, as indicated by the reference numeral 36 in FIG.

Bearings 37 are provided at both ends of each parallel roller member 22, and this bearing 37 is connected to the endless chain element 21.
A pin 38 protruding from the shaft is rotatably held, and in this way each parallel roller member 22 is rotatably stretched between a pair of endless chain elements 21. Further, in order to stably support the egg in a predetermined position on the parallel roller members 22, it is preferable to form a concave groove portion 39 around each parallel roller member 22.

Further, as shown in detail in FIG. 3, a bottom heat shield plate is disposed in the heating area, that is, in the heating housing 8, below the running path of the parallel roller member 22, so that the far infrared rays emitted from the thermal radiation source 12 are The bottom of the heating housing 8 is prevented from leaking.
As shown, guide rails 40 for the endless chain elements 21 are provided within the heating housing 8 along both sides of the bottom heat shield. This guide rail 40 is supported by suitable support beams 41. By stabilizing the running of the endless chain element 21 with the guide rail 40, the parallel roller member 22 can stably transport the eggs supported thereon. Also, as shown in Figure 3,
Another rail member 32 is positioned along the guide rail 40 to engage opposite ends 42 of the parallel load member 22 so that the parallel roller member 22 rotates on the rail member 40 as it travels within the heated housing 8. You will be forced to move while doing so. Due to this rotation of the parallel roller members 22, the eggs supported thereon are rolled through the heating housing.

Next, in order to operate the above-described egg cooking device 1, first, an egg is placed between the concave grooves 39 of the adjacent parallel roller members 22 at the entrance portion of the heating housing 8 (that is, on the left side in FIG. 1). and support it. The eggs supported on the parallel rollers 22 are then conveyed into the heating housing 8 where they are irradiated with far-infrared rays from the thermal radiation source 12. At this time, the egg is constantly rotated on the parallel roller member 22. After being irradiated with a predetermined amount of far-infrared rays, the eggs are cooked as so-called boiled eggs, and these boiled eggs are carried out from the exit portion of the heating housing 8 (ie, the right side in FIG. 1). As mentioned above, since the thermal radiation source 12 is vertically movable, the amount of far-infrared rays irradiated to the eggs can be adjusted. That is, when the thermal radiation source 12 is moved upward, the amount of far infrared rays irradiated to the egg becomes smaller, and on the other hand, when the thermal radiation source 12 is moved downward, the amount of far infrared rays irradiated to the egg becomes smaller. The amount of far-infrared rays irradiated increases. Through such adjustment, it is possible to obtain, for example, whole-boiled eggs or soft-boiled eggs.

In order to obtain uniformly boiled eggs, it is necessary to keep the ambient temperature within the heating housing 8 constant, and such constant ambient temperature is achieved by the exhaust blower 19.

The infrared radiators used in this example include known infrared radiators such as silicon carbide rods, tungsten lamps, and iodine lamps, and the far-infrared radiators include zirconia, titania, alumina, and β-based infrared radiators. - There are known far-infrared radiators such as sponge ceramics and the like.

(e) Effects of the invention As is clear from the above description, according to the invention, aged eggs can be produced without using boiling water, so there is no danger when handling boiling water as in the conventional case. be excluded.

Further, according to the present invention, since the eggs are continuously rotated, the egg yolk is not unevenly distributed, and a large amount of matured eggs such as fully matured eggs located in the center of the egg can be continuously produced.

Furthermore, since it is easy to adjust the position of infrared rays or far-infrared rays relative to eggs, it is easy to produce whole-boiled eggs and soft-boiled eggs.

Further, in the present invention, since the exhaust port equipped with an exhaust blower is provided in the ceiling of the housing, the atmospheric temperature within the heating housing can be kept constant. Moreover, since rotation does not cause directional problems due to heating, etc., it is possible to produce a large quantity of homogeneous aged eggs. In this way, since the heating atmosphere is homogeneous and the eggs do not come into contact with each other, a decrease in yield due to breakage of eggshells, etc., can be avoided.

Moreover, in the present invention, since the pores of the eggshell are sealed and made airtight by infrared or far infrared heating, it is possible to obtain aged eggs that are extremely hygienic and hard to spoil.

As described above, the present invention is superior to the conventional boiled egg production apparatus, and has a large influence on others.
