Description

[Detailed description of the invention] (a) Field of industrial application The present invention relates to an oven for producing aged eggs, and in particular, to an oven for dry producing aged eggs, that is, whole-boiled or soft-boiled eggs.

(b) Prior art Aged eggs are generally made by placing eggs in a container such as a pot, adding enough water to cover the eggs, heating them, and once the eggs come to a boil, reduce the heat and continue boiling. It is produced by quenching it in water. However, when boiling multiple eggs at the same time or heating them rapidly, the eggs become upset due to the foaming during boiling.
The shells of eggs are destroyed by the impact caused by contact between eggs or by contact between eggs and container walls, which is not sanitary.

Furthermore, to boil eggs, it takes an additional 10 minutes to heat the water after it boils, and if you don't rotate the egg sufficiently while the water boils, you won't be able to get a fully ripe egg with the yolk in the center. It is time-consuming and troublesome.

(c) Structure The present invention solves all the problems of conventionally producing aged eggs at home. The present invention provides an oven for producing aged eggs.

The present invention includes a heating housing, an infrared ray radiator or a far-infrared ray radiator provided in the housing, and a rotatable member located below the radiator and within the housing, the size of which is smaller than an egg. A plurality of cylindrical members are formed with circumferentially extending circular grooves having a width of . The eggs are aged in an oven.

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.

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 circular groove is formed to place the eggs to be ripened and heated. By forming the circular groove in the cylindrical member in this way, when a plurality of eggs are heated, contact between the eggs and eggs is prevented. Shocks caused by contact with the vessel wall can be avoided.

Moreover, in the present invention, since the egg is placed in the circular groove of the cylindrical member, it can be constantly rotated by rotating the cylindrical member under infrared or far infrared heating, and the entire egg can be rotated. Whole-boiled eggs that are heated evenly and have the yolk located in the center can be easily produced. Moreover, the rotation of the cylindrical member can be achieved by providing a pulley or a gear on at least one end of the cylindrical member, or by providing them removably to transmit the rotational motion of a drive source such as a motor to the cylindrical member. I can do it.

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.

(D) Embodiment FIG. 1 is a schematic side sectional view showing an embodiment of the oven for producing aged eggs of the present invention, and FIG.
It shows a schematic cross-sectional view of an example of a roller member used in the oven.

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 side parts on both sides (one side part is omitted and not shown). has been done.

The opening of the front part 3 is provided with a lid element 7 which can be opened and closed to allow the egg to be heated to be taken in and out of the heating housing. It is rotatably attached to 2 with a hinge or the like. The lid element 7 can be made of transparent heat-resistant glass so that the object to be heated housed in the heating housing can be seen from the outside. Although not shown in FIG. 1, the bottom portion can be configured to be openable and closable, as in the conventional case, so that the inside of the heating housing can be easily cleaned. In this embodiment, the object to be heated is placed in the heating housing 2.
Three holding roller members 8 made of, for example, a metallic material are arranged horizontally and parallel to each other in the heating housing 2 in order to hold the heating housing 2 inside. Both ends of these holding roller members 8 are rotatably supported by both sides of the heating housing 2 (see FIG. 2). Around the holding roller member 8,
At least one groove 9 (three in FIG. 2) is formed. The groove 9 formed around each holding roller member 8 is aligned with the groove 9 formed around the adjacent holding roller member 8. Therefore, due to the grooves of the two rollers,
A holding seat is formed between the two rollers 8,8. In this case, the groove 9 is formed in a shape that can be adapted to the contour of the egg 9'.

Further, in this embodiment, the driving means for rotating the three holding roller members 8 in the same direction around their longitudinal axes and almost synchronously is attached to the bottom of the heating housing 2. This electric motor 10
A motion transmission mechanism 11 using, for example, a belt, gears, etc., for transmitting the rotational motion of the holding roller member to the holding roller member.
It consists of As shown in FIG. 2, in the illustrated embodiment, the motion transmission mechanism 11 includes an electric motor 10
An output pulley 13 provided on the output shaft 12 of
It consists of an output pulley 14 provided at one end of the three holding roller members 8, and a drive belt stretched around the belt engaging portions 15 of these output pulleys. Another example of such a motion transmission means is a motion transmission mechanism using gears or gears and a drive chain, respectively, instead of the above-mentioned pulleys and drive belts. Furthermore, as another aspect of such a motion transmission mechanism, one or two of the three holding roller members 8 are rotatably driven by the electric motor 10, and the other holding rollers 8 are rotatably supported. One or two of the rotationally driven holding rollers 8 may be rotated to transmit the rotational movement of the holding roller member to the other holding roller members 8. In short, in the present invention, it is only necessary to drive the holding roller members 8 to rotate substantially in synchronization in the same direction, and various types of driving means can be used for this purpose.

Furthermore, in this embodiment, in order to heat the object held on the holding roller member,
Two infrared ray emitters or far-infrared ray emitters 16 are provided in the upper part of the housing 2. The infrared radiators used here include silicon carbide rods,
Known infrared emitters such as tungsten lamps and iodine lamps are used.

Further, as the far-infrared radiator, a far-infrared radiator such as ceramics such as zirconia, titania, alumina, and β-spongemene is used. These infrared ray radiators or far-infrared rays radiators 16 are equipped with reflectors for directing far-infrared rays toward the object to be heated on the holding roller member 8. In the illustrated embodiment, the far-infrared ray emitter 16 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.

When producing boiled eggs in the illustrated oven, first, the eggs are placed on the egg holding seats formed by the grooves 9 of the adjacent holding roller members 8, and then,
By rotationally driving the holding roller member 8, the eggs 9' are rotated thereon, and the eggs 9' are heated by far infrared rays for a predetermined period of time.
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.

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.

(e) Effects of the invention The oven of the invention can heat eggs while rotating at a fixed position while being supported by rollers, so it is possible to avoid cracking of the eggshell when boiling eggs as in the conventional method. However, it can be manufactured with good yield.

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 constantly rotated on the holding roller member during ripening and heating of the egg, it is possible to make a clean boiled egg in which the yolk is located in the center of the white when sliced into rounds.
