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 manufactured by quenching it in water.

(c) Problems that the invention aims to solve However, when boiling multiple eggs at the same time or heating them rapidly, the eggs become agitated due to the foaming during boiling, causing the eggs to come into contact with each other or The impact caused by contact with the container wall destroys the egg shell, which is not sanitary.

Furthermore, in order 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 comes to a boil, you won't be able to get a fully ripe egg with the yolk in the center. It is time-consuming and troublesome.

(d) Means for solving the problems The present invention solves all the problems of conventionally producing aged eggs at home. To provide an oven for producing aged eggs that can automatically cook and produce eggs.

The present invention has an opening for taking out, and
A heating housing in which at least a plurality of through holes are formed in a wall portion with an opening/closing lid, an infrared ray emitter or a far infrared ray emitter provided in the housing, and above or below the radiator. a stirring fan located below the radiator; and an arcuate concave extending in the circumferential direction having a motion transmitting element at one end and having a width slightly larger than the size of an egg at most. A cylindrical member having a cylindrical portion in which a groove is formed, a frame body that supports these cylindrical members while maintaining a spacing equal to or less than an egg width dimension from each adjacent cylindrical member, and a motion transmission element for the cylindrical member. An oven for producing aged eggs, characterized in that it is provided with a drive device which engages via an intermediary motion transmission element.

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 within the oven. The position of the fan is such that it does not speed up the heating of the object to be heated.
Any position can be used as long as the gas inside the oven can be stirred.

Further, in the present invention, an air supply port is formed through the housing in order to lower the temperature inside the heating chamber. The air supply ports can be opened and closed, and are provided in an appropriate size and number depending on the size of the heating chamber of the oven. The position where the air supply port is formed is so that air can be supplied by the action of a stirring fan.
Preferably, it is provided around the stirring fan. In this way, since outside air is introduced into the housing, the housing wall has a
An exhaust port is formed so that it can be opened and closed.

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. 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 detachably to transmit the rotational motion of a drive source such as a motor to the cylindrical member. .

In addition, in the present invention, the cylindrical member is divided into a driving cylindrical member and a driven cylindrical member, and a friction wheel, a gear, etc. is provided at one end of the driven cylindrical member, and a friction wheel, a gear, etc. of the driving cylindrical member, By engaging a gear or the like via an intermediary element, rotational movement of the motive cylindrical member can be transmitted to the driven cylindrical member.

In this case, the rotation of the driving cylindrical member is achieved by coupling the driving cylindrical member to the rotating shaft of the drive source via a coupling provided on the driving cylindrical member, thereby coupling the rotational movement of the rotating shaft of the driving source. This is done by transmitting the signal to the motive cylindrical member via the cylindrical member. The drive source can be connected to or detached from the rotary shaft by means of the driving coupling while the rotary shaft is in operation and when the rotary shaft 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. In this case, a mechanical clutch, an electromagnetic clutch, etc. can be used as the clutch.

A rotating shaft serving as a driving source for rotating the motive cylindrical member is provided so as to be connectable to a rotating shaft of a power source such as a motor directly or via a pulley, sprocket, gear, or the like. 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, the eggs are supported by the cylindrical member for rotational transfer, so that the eggs can be heated uniformly by infrared rays or far infrared rays without making them come into contact with each other. . 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.

This invention has a stirring fan inside the oven, as well as air supply and exhaust ports that can be opened and closed, making it possible to stir the inside of the oven to a uniform temperature, allowing the eggs to be heated evenly, making it possible to break the eggs. The rate can be reduced. Moreover, since one part of the cylindrical support is used as a drive source and is connected to a drive source such as a motor using a clutch, the mechanism for rotating the cylindrical member on its axis is simplified, and the removal of boiled eggs is simplified. can be easily done.

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) Example FIG. 1 is a schematic side sectional view showing an example of the oven for producing aged eggs of the present invention, and FIG.
FIG. 2 is a partial plan view of FIG. 1;

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 that can be opened and closed to allow eggs 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 the drawings, as in the conventional case, the bottom portion can be configured to be openable and closable, 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, the heating housing 2 includes 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 support frame 9 (see FIG. 2). At least one groove 10 is formed around the holding roller member 8. 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, a holding seat is formed between the two roller members 8, 8 by the grooves of the two roller members. 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 around their longitudinal axes and almost synchronously is an electric motor attached to the bottom of the heating housing 2. A motor 11 and a rotating shaft 1 for driving the rotational movement of the electric motor 11 and a drive holding roller member 12.
For example, a motion transmission mechanism (not shown) such as a belt, gears, etc. is used to transmit the motion to the motor. As shown in FIG. 2, in this example, the motion transmission mechanism includes an output sprocket 15 provided on the output shaft 14 of the electric motor 11 and a drive rotating shaft 1.
an output sprocket 16 provided at one end of 3;
It consists of a drive chain (not shown) that spans these output sprockets. 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 sprocket and drive chain described above. In this example, a plurality of holding roller members 8 are
One of them is used as a rotational driving force, and the gear part 17 of the other holding roller 12' is rotatably supported, and the driving holding roller 12 for rotational driving is rotated.
The rotational motion of the driving holding roller 12 is transmitted to another driven holding roller 12' via a gear 17'. In short, in the present invention, it is sufficient to rotate the holding roller member 8 in the same direction substantially synchronously, and various types of driving means can be used for this purpose.

In this example, the driving force holding roller 12 for rotational drive is
A clutch 18 is provided at one end to enable engagement and disengagement.

Furthermore, in this example, an infrared ray emitter or a far infrared ray emitter 20 having three reflectors 19 is provided in the upper part of the housing 2 in order to heat the object to be heated held on the holding roller member. It is provided. The infrared emitter used here is
Known infrared emitters such as silicon carbide rods, 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, β, and sponge ceramics is used. These infrared ray radiators or far-infrared rays radiators 20 are equipped with reflectors for directing far-infrared rays toward the object to be heated on the holding roller member 8. In this example, the far-infrared radiator 20 is a heating housing 2
Although a similar far-infrared ray body is provided only in the upper part, a similar far-infrared ray body can also be provided in the lower part.

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

Further, an air supply port 23 is provided in the ceiling portion 5 above the stirring fan 2 by forming a through hole 23 therein. This air supply port 23 can be opened and closed by a damper 24. 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 housing to a predetermined temperature. In this example, an exhaust port 25 is formed in the lower part of the housing, and the amount of fresh air introduced from the air supply port is discharged by opening the exhaust port 25, which can also be opened and closed. A temperature sensor is provided on the housing forming wall 2, so that the temperature inside the housing 2 can be determined.
Further, by using the sensor 26 to configure an appropriate temperature control circuit (not shown), the temperature can be automatically controlled.

When producing boiled eggs in the illustrated oven, the eggs are first placed on the egg holding seats 10 formed by the grooves 10 of the adjacent holding roller members 8, and then the holding roller members 8 are driven to rotate. By rotating the eggs, the eggs are rotated on them, 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, the temperature inside the 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 sensor 26
By arranging the housing 2, the temperature inside the housing 2 can be easily grasped, and thereby the damper 24 can be opened and closed to perform desired heating. In addition, 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 is opened, the frame body 9 is pulled toward the door, and the egg is taken out to the outside.

In the oven of this example, a stirring fan is provided at the top, and an air intake hole is provided above it so that the temperature can be adjusted, so that stirring convection can occur when heating eggs, and uneven heating of eggs can be prevented. Prevented.

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, such as hot spring eggs. When opening in this example, the roller member 8 can be made detachable.

The oven of this example can be used to heat bread etc. without rotating the roller member 8,
Further, by using the roller member 8 as a suitable support member, it can be used for heating bread, etc.

In this example, when producing fully mature eggs such as boiled eggs, if 35 eggs were prepared and the heating time was 30 minutes, only one egg broke, and the egg breaking rate was just under 3%. However, when no stirring fan is provided, the egg breaking rate is approximately 40%, which indicates that the yield of aged eggs in the present invention is significantly improved.

In addition, if a stirring fan and air supply port are not provided,
Production of soft-boiled eggs such as hot spring eggs was difficult and took a lot of time because temperature control was difficult, but by installing a stirring fan and air supply port, temperature control using a temperature sensor, etc. became possible, making the production of soft-boiled eggs simple and easy. Summer.

(g) Effects of the invention In the oven of the invention, eggs are supported on rollers and heated while rotating at a fixed position.In addition, an air supply port and an exhaust port that can be opened and closed are provided, and a stirring fan is provided to stir the eggs. Since the flow is formed, the temperature inside the housing becomes uniform and temperature control becomes easy, and cracking of the egg shell when boiling eggs as in the conventional method can be avoided, and boiled eggs can be produced with a high 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.

Furthermore, in the present invention, since the egg is always rolled on the holding roller member during cooking, it is possible to produce beautifully boiled eggs in which the yolk is located in the center of the white when sliced into rings.
