Each of these cylindrical members has at least one arc-shaped concave groove extending in the circumferential direction with a width no larger than the size of an egg, and the concave grooves facing each other in the adjacent cylindrical members are for egg-shaped grooves. The oven for producing aged eggs is characterized by forming a holding seat.

In the present invention, the infrared radiator or far-infrared radiator is used because light in the infrared or far-infrared wavelength range passes through the eggshell and directly heats the egg yolk and albumen inside the shell, so it can be heated in an extremely short time. It can be heated. The light in the infrared or far infrared wavelength range to be used includes infrared or far infrared rays in the wavelength range of 1 μm to 25 μm, especially 2.5 to 10 μm, since it includes the water absorption wavelength band and the protein absorption wavelength band. preferable.

In the present invention, a stirring fan is provided to equalize the temperature inside the oven. The position of the fan is such that it does not interfere with the heating of the object to be heated.
It can be placed in any position as long as it can stir the gas inside the oven.

Further, in the oven for producing aged eggs of the present invention, the cylindrical member is a hollow or solid rolling element with a circular cross section, and the cylindrical member has a width not larger than the size of an egg in the circumferential direction. An extending arcuate groove is formed to place eggs to be ripened and heated.By forming the arcuate groove in the cylindrical member in this way, eggs can be placed during heating of a plurality of eggs. Shocks caused by contact between eggs and the container wall can be avoided.

Moreover, in the present invention, since the egg is placed in the arcuate groove of the cylindrical member, the egg can be constantly rotated by the rotation of the cylindrical member while being heated by infrared rays or far infrared rays. , it is possible to easily produce a fully ripened egg in which the whole egg is heated uniformly and the yolk is located in the center.

In the present invention, the cylindrical members include a driving cylindrical member and a driven cylindrical member, and the rotation of the driven cylindrical member is as follows:
A gear is provided at at least one end of the driven cylindrical member, and this gear is engaged with the gear of the driving cylindrical member via an intermediary gear to transmit the rotational motion of the driving cylindrical member to the driven cylindrical member. This is done by

The rotation of the motive cylindrical member is achieved by connecting the rotating shaft of the drive source to the rotation shaft of the drive source via a coupling provided on the motive cylindrical member.
This is accomplished by connecting the driving cylindrical members and transmitting the rotational movement of the rotation shaft of the drive source to the driving cylindrical members via the coupling. Connecting or disconnecting the drive source to the rotating shaft using the drive coupler,
This can be done while the rotating shaft is in operation and when it is stopped. A clutch can be used to allow the motive tube member to be connected to or removed from the rotating shaft without stopping the rotation of the rotating shaft. As the clutch in this case, a mechanical clutch, an electromagnetic clutch, etc. can be used.

A rotating shaft serving as a driving source for rotating the driving cylindrical member is connected to a rotating shaft of a power source such as a motor directly or via a pulley, sprocket, gear, or the like.

In the present invention, the position of the driving cylindrical member can be selected from any position as long as the driven cylindrical member can rotate. Further, the driving cylindrical member and the driven cylindrical member are rotatably supported by the frame at intervals that allow the egg to be placed in the arcuate groove. This frame is supported at both ends by two rails extending toward the door, and can be pulled out using a handle or the like.

(e) Effect In the aged egg manufacturing apparatus according to the present invention, eggs are held in the egg holding seats formed between adjacent grooves of the egg rotating cylindrical member, so that infrared rays can be absorbed without the eggs coming into contact with each other. Alternatively, it can be heated uniformly by far infrared rays. Moreover, since infrared rays and/or far infrared rays are used to heat the eggs, boiled eggs can be obtained in a short time. In this case, it is preferable to use far-infrared rays because the far-infrared rays can reach the center of the egg through the egg shell, so that not only the outer surface of the egg but also the center can be heated.

In addition, 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, so that contamination can be avoided.

In the present invention, since a stirring fan is provided inside the oven, the inside of the oven can be stirred to a uniform temperature, the eggs can be heated uniformly, and the egg breaking rate can be reduced. Moreover, since one of the cylindrical members is used as a drive source and is connected to a drive source such as a motor by a clutch, the mechanism for rotating the cylindrical members in the same direction and rotating the egg on its own axis is simplified. The eggs can be heated uniformly, and the boiled eggs can be easily taken out.

Therefore, in the present invention, eggs can be aged in a uniform manner, and the operation can be simplified.

Hereinafter, embodiments of the oven for producing aged eggs of the present invention will be described with reference to the accompanying drawings, but the technical scope of the present invention is not limited in any way by this description.

(F) Embodiment FIG. 1 is a schematic side sectional view showing an embodiment of the oven for producing aged eggs of the present invention, and is shown horizontally in the vertical direction. FIG. 2 is a partial plan cross-sectional view of the embodiment shown in FIG. 1, showing a planar cross-section centered on the holding roller member.

An oven 1 for producing aged eggs includes a heating housing 2. The heating housing 2 is made of a suitable metal material and includes a front part 3, a back part 4, a top part 5, a bottom part 6, and both side parts 6' (one side part is omitted and not shown). It is formed.

A door 7 that can be opened and closed is provided at the opening of the front part 3 to allow eggs to be heated to be taken in and out of the heating housing 2. Preferably, this door 7 has a lower part that closes to the heating housing 2. It is rotatably attached to the base with a hinge or the like. The door 7 is made of transparent heat-resistant glass, so that the object to be heated housed in the heating housing 2 can be seen from the outside. Although not shown in the drawings, as in the conventional case, the bottom portion can be configured to open and close automatically, so that the inside of the heating housing can be easily cleaned. In this embodiment, in order to hold the object to be heated within the heating housing 2,
Inside the heating housing 2, a plurality of holding roller members 8 made of, for example, a metal material are arranged horizontally and parallel to each other. Both ends of these holding roller members 8 are rotatably supported by a roller support frame 9 (see FIG. 2). Holding roller member 8
At least one groove 10 is formed around the periphery. The groove 10 formed around each holding roller member 8 is aligned with the groove 10 formed around the adjacent holding roller member 8. Therefore, the concave grooves of the two holding roller members 8 form an egg holding seat 10 between the two adjacent roller members 8, 8. In this case, the groove 10 is formed in a shape that can match the contour of the egg.

Further, in this example, the driving means for rotating the holding roller members 8 in the same direction and synchronously around their longitudinal axes is an electric motor attached to the bottom surface of the heating housing 2. 11, and a motion transmission mechanism (not shown) such as a belt, gears, etc., for transmitting the rotational motion of the electric motor 11 to the drive rotating shaft 13 of the drive holding roller member 12.

As shown in FIG. 1, in this example, the motion transmission mechanism is provided at an output sprocket 15 provided on the driving rotation shaft 14 of the electric motor 11 and at one end of the drive shaft 13 of the drive holding roller member. output sprockets 16 and a drive chain (not shown) that spans these output sprockets.
It consists of.

Another example of such a motion transmission means is a motion transmission mechanism in which a drive belt is passed between pulleys in place of the output sprocket and drive chain described above.

In this example, as shown in FIG. 2, one of the plurality of holding roller members 8 is a driving holding roller member 12, and the other is a driven holding roller member 12'. The gear part 17 is rotatably supported. In order to rotate the holding roller member 8, the driving holding roller member 12 is rotated by the electric motor 11, and the rotational movement of the driving holding roller member 12 is transferred to the holding roller member 12 for the driving side. This is transmitted to the roller member 12' via the intermediate gear 17. As described above, in the present invention, the holding roller members 8 only need to be driven to rotate in the same direction and approximately synchronously, and a mediating gear is provided as a driving means for this purpose.

In this example, a clutch 18 is provided at one end of the holding roller member 12 for the driving force for rotational driving, and the clutch 18 can be engaged and disengaged.

Furthermore, in this example, as shown in FIG. A body or far-infrared radiator 20 is provided. As the infrared radiator used here, known infrared radiators such as silicon carbide rods, tungsten lamps, and iodine lamps are used.

Further, as the far-infrared radiator, an infrared ray radiator such as ceramics such as zirconia, titania, alumina, and β-spongemene is used. These infrared ray emitters or far infrared ray emitters 20 are equipped with a reflecting plate 19 for directing far infrared rays toward the object to be heated on the holding roller member 8. In this example, the far infrared ray emitter 20 is provided only in the upper part of the heating housing 2, but a similar far infrared ray emitter can also be provided in the lower part.

Furthermore, a stirring fan 21 is installed to ensure uniform temperature.
is provided. The stirring fan 21 is an electric motor 2
2.

Further, on the top surface portion 5 above the stirring fan 21,
A plurality of air supply ports 23 are provided around the stirring fan. This air supply port 23 is controlled by a damper 24.
It can be opened and closed. In this example, eight air supply ports 23 are formed around the stirring fan 21. By opening the damper 24, the air supply port 23 can lower the temperature inside the heating housing 2 to a predetermined temperature. In this example, an exhaust port 25 is formed at the lower part of the side surface 6' of the heating housing 2, and the amount of fresh air introduced from the air supply port 23 is absorbed by the side surface 6'.
It is discharged from the exhaust port 25 at the bottom. A temperature sensor 26 is provided on the forming wall of the heating housing 2, and the temperature inside the heating housing 2 can be determined. Further, by using the temperature sensor 26 and configuring a suitable temperature control circuit (not shown), the temperature can be automatically controlled.

When producing boiled eggs in the oven shown in FIGS. 1 and 2, first open the door 7 and open the egg holding seat 10 formed by the groove 10 of the adjacent holding roller member 8. Place an egg in each, then
By rotationally driving the holding roller member 8, the eggs are rotated thereon, and the eggs are heated by far infrared rays for a predetermined period of time.

Since the stirring flow 27 is formed by the action of the stirring fan 21, the temperature inside the heating housing 2 becomes uniform, eliminating the difference in temperature between the upper and lower sides, and improving heating efficiency. In addition, in this example, the temperature sensor 26 is arranged so that the temperature inside the housing 2 can be easily grasped.
4 can be opened and closed to perform desired heating. Note that it is preferable to take the boiled egg obtained after heating for a predetermined period of time into cold water. This is because the shell of a boiled egg will easily peel off.

Further, in this example, in order to improve the irradiation efficiency of far infrared rays, the inner wall of the housing is made of stainless steel or the like and is formed into a mirror-like surface.

In this example, when a whole or half-boiled egg is to be taken out, the door 7 can be opened, the support frame 9 can be pulled toward the door 7, and the egg can be taken out to the outside.

Moreover, by controlling the irradiation time of the infrared ray emitter or the far-infrared ray emitter, it is also possible to make eggs in a half-boiled state. In the oven of this example, the roller member 8 can be made detachable.

(g) Effects of the invention The oven of the invention is supported by rollers and can be heated at a fixed position while rotating under an atmospheric temperature controlled by the action of a stirring fan, etc. Cracking of egg shells when boiling eggs can be avoided, and boiled eggs can be produced with a high yield.

In the present invention, the egg receiving shelf is formed by arranging rotatable cylindrical members, and the cylindrical member of this shelf is rotated by a driving cylindrical member, and this driving cylindrical member is connected to a coupling such as a clutch. Since it is removable from the drive shaft through the cable, the shelf can be used to store aged eggs such as boiled eggs, soft-boiled eggs, hot spring eggs, etc.
This allows the eggs to be pulled out of the oven, making it easier not only to take out the eggs but also to arrange the eggs during charging, thereby avoiding troubles when loading and unloading the eggs. Therefore, in the present invention, the yield of aged eggs can be improved.

Furthermore, since the present invention uses infrared rays and/or far infrared rays from an infrared ray radiator or a far-infrared ray radiator, heating efficiency is excellent, and fully ripened eggs can be produced in an extremely short time. Therefore, generation of hydrogen sulfide due to long-term heating, etc. can be reduced.

Furthermore, by infrared and/or far-infrared heating, the pores existing in the eggshell are sealed, so the eggshell is ripened without contamination, making it sanitary and resistant to spoilage.

Further, in the present invention, since the egg is always rolled on the holding roller member during cooking, it is possible to make a clean boiled egg in which the yolk is located in the center of the white when sliced into rings.
