Then, the input port of a hopper 12 is adjusted to the opening of the barrel, and heated balls are input in the barrel 80 by opening the shutter of the hopper 12, and the shutter is closed when a meter detects a specified weight. To the hopper 12, a quantity of heated balls which is equivalent to the input quantity is replenished from a ball heating unit 11. After the filling of the heated balls to the barrel 80, the opening is closed, and the barrel 80 is shaken by rotating the barrel 80 by the operation of a barrel shaking/rotating unit 13. By doing this, the heated balls are shaken in the barrel 80 so that the inner surface of the barrel 80 may be thoroughly sterilized and carbonized.

Description

Detailed Description of the Invention

[0001]

This invention relates to whiskey, wine,
The present invention relates to a reprocessing method for reusing a wooden barrel used for storage and aging of some shochu.

[0002]

2. Description of the Related Art Barrels used for storage and aging of whiskey, wine, some shochu, etc. are made of wood such as oak, but if used for a certain period of time, deposits and various bacteria will adhere to the inner surface, and
Leachables from wood that produce the taste and color of sake are lost. For this reason, if you want to use a barrel that you used once again,
The inside must be cleaned with water or detergent, and the inside surface must be heated by a burner for sterilization and surface carbonization to be regenerated.

[0003]

However, the barrel is usually
There is only one small opening (usually about 7 cm in diameter) for taking in and out of stored liquid such as whiskey,
The burner cannot be inserted deep inside the barrel. Therefore, conventionally, a part of the barrel was disassembled, cleaned, burner heating work was performed, and then the barrel was reassembled. However, if you disassemble the barrel and heat only one side of the barrel, body plate, etc. that compose the barrel, these plates will be slightly deformed from the state before disassembly,
It is very difficult to assemble it watertight again. For this reason, the conventional barrel regeneration work requires highly skilled techniques and long-time work.

The present invention has been made to solve the above problems, and provides a method and an apparatus therefor capable of heating the entire inner surface as it is without disassembling the barrel. To do.

[0005]

A method of regenerating a wooden barrel according to the present invention made to solve the above-mentioned problems is to provide a large number of heated metal or ceramic bodies from the opening of the wooden barrel. By putting it inside and swinging and rotating the wooden barrel,
The entire inner surface of the wooden barrel is heated.

[0006] It should be noted that a large number of metal bodies are used and placed inside the wooden barrel without heating (or after being heated and then placed inside the wooden barrel), and the metal bodies are placed from outside the wooden barrel. A method of swinging and rotating the wooden barrel while inducing heating can also be used.

The most suitable devices for carrying out such a method are: a) a heating device for heating a metal or ceramic body, and b) a heated metal or ceramic body for opening a wooden barrel. It is desirable to have a heating small body charging mechanism for charging the wooden barrel into the inside of the wooden barrel, and c) a barrel swinging and rotating mechanism for holding, swinging and rotating the wooden barrel. Here, similarly to the above, an induction heating device for inductively heating the above-mentioned metal bodies introduced into the wooden barrel may be provided outside the wooden barrel. In this case, it is not necessary to provide a device (above a) for heating the metal small body before putting it into the wooden barrel.

The term "small body" as used herein means a sphere, an ellipsoid, a polyhedron or the like having a diameter smaller than the diameter of the opening of the barrel. The size does not necessarily have to be constant, but rather it is preferable that various sizes from large size to small size are mixed.

[0009]

[Function] Whether the preheated metal or ceramic body is put in the barrel or the metal body is induction-heated after being put in the barrel (or the preheated metal body is When placed inside the barrel and also subjected to induction heating), the hot metal or ceramic particles contact the inner surface of the barrel to heat the inner surface for sterilization and carbonization. In addition, the inner surface is physically cleaned by collision and friction between the small body and the inner surface of the barrel, and deposits on the inner surface are removed.

[0010]

The wheel gear 19 is provided in the. The wheel gear 19 meshes with the worm gear 20, and the oscillating motor 21 that drives the worm gear 20 periodically rotates in the forward and reverse directions, so that the oscillating table 16 oscillates periodically. The swing angle of the swing table 16 can be arbitrarily changed by changing the forward / reverse rotation cycle of the swing motor 21 (the number of rotations in the forward rotation period and the number of rotations in the reverse rotation period). .

Slide tables 23 and 24, which slide left and right, are erected at both ends of the swing table 16, and a screw running substantially in the center of the swing table 16 is provided at the lower center of both slide tables 23 and 24. The shaft 25 penetrates. The screw shaft 25 is rotated by a clamp motor 26, and by positively rotating the clamp motor 26, both slide tables 23 and 24 move to the center side and approach each other to clamp the barrel 80. By rotating the clamp motor 26 in the reverse direction, the two slide tables 23 and 24 are separated from each other, and the clamp of the barrel 80 is released.

A circular holding plate 28 is attached to each of the slide tables 23 and 24 via universal joints 30 and 31, respectively.
29 are provided. On the inner surface side of the pressing plates 28 and 29 (the side on which the barrel 80 is clamped), the barrel 80 to be processed is provided.

As shown in FIG. 2, the hopper unit 12 includes a hopper 37, a weight scale 38, and a shutter 39, and the entire hopper unit 12 can be moved vertically and horizontally by a hopper moving mechanism (not shown). Inlet 40 at the bottom of hopper 37
Is slightly smaller than the size of the opening 83 of the barrel 80 (usually about 7 cm).

The ball heating unit 11 provided at the upper portion of the hopper 37 has a large number of ceramic or metal balls 41.
A main body 42 for storing the water, a heater 43 provided around the main body 42, and a ball loading port 4 provided on the upper part of the main body 42.
4 and a payout opening 45 provided at the bottom of the main body 42. Also, a thermometer (not shown) that detects the internal temperature
Is also provided. A shutter 46 is provided at the payout opening 45. The heater 43 can heat the ceramic balls or the metal balls 41 inside the main body 42 in the range of about 300 to 800 ° C. Although an electric heater is used as the heater 43 in FIGS. 1 and 2, gas flame heating,
Oil combustion heating or indirect heating by blowing hot air may be used.

Of course, the ceramic balls or metal balls 41 must be smaller than the opening 83 of the barrel 80, but preferably they are larger in terms of heat capacity. On the other hand, on the other hand, the inner surface of the barrel 80 is closely spaced, especially the body 81 and the mirror
A small ball is preferable in order to heat and carbonize the boundary (corner) portion between and. Therefore, it is desirable that the balls 41 to be put into the barrel 80 are a mixture of balls of various sizes (for example, a mixture of balls having a diameter of about 1 to 3 cm). The ball does not have to be a sphere,
For example, a spheroid or a cube may be used.

Next, a method of regenerating the barrel 80 with this apparatus will be described. First, the slide tables 23 and 24 are moved by the clamp motor 26, and the barrel 80 to be processed is clamped by the two holding plates 28 and 29. Next, the barrel rotation motor 35 is rotated to open the opening 8 of the barrel 80.
When 3 comes directly above, it stops rotating. The position of the inlet 40 of the hopper 37 is aligned with the opening 83 by a hopper moving device (not shown), and the shutter 39 is opened. As a result, the heated balls 41 are thrown into the barrel 80. During this period, the control device monitors the amount charged by the weight scale 38, and closes the shutter 39 and stops the charging when the heating ball 41 having a predetermined weight is charged into the barrel 80.
The amount of heating balls 41 corresponding to the amount thrown in is
It is supplied from the ball heating unit 11 to the hopper unit 12. Barrel 8
After a predetermined amount of the heated balls 41 is loaded into 0, a stopper 84 (FIG. 4) is placed in the opening 83 of the barrel 80, and the hopper unit 12 is released by the hopper moving mechanism in the direction away from the barrel 80. In addition, it is desirable to use the plug 84 having air permeability in order to discharge water vapor, gas, smoke and the like generated when the inner surface of the barrel 80 is heated.

After that, the barrel 80 is rotated by the barrel rotation motor 35 and is also swung by the swing motor 21. The state of the barrel swinging rotation unit 13 at this time is shown in FIG.
Due to this rotation and swing movement, a group of heating balls 41 move all over the inside of the barrel 80 and heat the inner surface without any gap. An example of the movement of the group of heating balls 41 is shown in FIG. FIG. 6 is an exploded view of the barrel 81 of the barrel 80,
Each line of the 1st time to the 5th time represents the locus of the movement of the group of the heating balls 41 during the rotation of the barrel 80 five times. By combining the rotation and swing speeds appropriately,
As shown in FIG. 5, a group of heating balls 41 can heat and carbonize the inner surface of the barrel 80 without any gap.

When the inner surface of the barrel 80 is actually heated and carbonized, the following various conditions are involved, and the control device should take the above into consideration and perform the following process. desirable. (1) The portion that is the bottom when the heating ball 41 is first charged into the barrel 80 (the inner surface just opposite to the opening 83) is heated and carbonized when the heating ball 41 is charged, so that it shakes. At the time of movement and rotation, the passing speed of the heating ball group in this portion should be increased. (2) Since the ball group passes twice in the center part of the body in one cycle of rocking, the center part is rocked slightly (near the position where the central axis of the barrel is horizontal), and both ends (mirror (Part) near the end of the rocking. (3) Since the temperature of the heating ball 41 is lowered during the processing, the swinging / rotating speed is gradually decreased.

In order to heat and carbonize not only the body portion 81 but also the inner surface of the mirror portion 82, as shown in FIG. 4, the barrel rotating motor 35 with the swing table 16 largely tilted.
It is also necessary to rotate by.

After completing the predetermined rotation and swinging, the stopper 84 of the opening 83 of the barrel 80 is pulled out, the swinging table 16 is inverted as shown in FIG. All the heating balls 41 inside are discharged. At this time, by rotating the swing motor 21 and the barrel rotation motor 35 forward and backward little by little, it is possible to quickly discharge all the balls 41. The discharged balls 41 are collected at one place through the gutter, and after removing dust and the like, they are loaded into the ball heating unit 11 by human power or an automatic device and reused.

The above-described ball throwing, rotating / swinging, and discharging processes can be repeated for one barrel 80 several times as required. In this case, it is desirable that a program be created in advance in the control device and a series of operations be executed by automatic control. In addition, the charging amount of the balls 41, the heating temperature,
Regarding the swing and rotation speed, the size and material of the barrel 80,
It is desirable to set an optimal value in advance according to the kind of stored material and to program it.

In the above embodiment, the case where the opening 83 is provided in the center of the body has been described. However, in the case of the barrel having the opening 83 in the mirror portion 82, one of the barrels 80 is set up as shown in FIG. The heating balls 41 may be fed into the barrel 80 through the through holes provided in the pressing plate 29.

Next, a second embodiment of the present invention will be described with reference to FIG. In the example of FIG. 7, in addition to the device of the first embodiment, electromagnetic induction heating devices 50 and 51 fixed to the swing table 16 are provided close to the barrel portion 81 and the mirror portion 82 of the barrel 80. In the reproducing apparatus of this embodiment, the ball heating unit 1
The heating ball 41 previously heated by 1 is put into the barrel 80, and the heating ball 41 inside is continuously heated by the induction heating devices 50 and 51 even while the barrel 80 is being rocked. It can be heated and carbonized. In addition, without providing the ball heating unit 11,
All may be heated by the induction heating devices 50 and 51. In FIG. 7, it is desirable that the induction heating device 50 of the body 81 is arranged so as to avoid the blush 85. The induction heating device 5 for the body 81 and the mirror 82
0, 51 are not always energized, but only the induction heating device 50 of the body 81 when the internal heating balls 41 are in the body 81, depending on the tilt angle of the swing table.
When one of the mirror portions 82 is present, only the induction heating device 51 of the mirror portion 82 on that side may be switched to switch the induction heating device to be energized.

In the case of the present embodiment, since the balls 41 are made of electromagnetic induction heating, it is necessary that the balls 41 be made of metal. It is desirable to select a metal with good electromagnetic induction heating efficiency. In this case, the surface of the metal ball 41 may be coated with ceramic to prevent the metal powder from adhering to the inner surface of the barrel 80. Further, in the case of a metal material such as SUS303 stainless steel that can be induction-heated and is not easily oxidized at room temperature and high temperature, it can be used as it is without coating.

The barrel swinging and rotating unit 13 of the above embodiment is
Before performing the above-mentioned inner surface heating treatment, the barrel 41 which is not heated and the water or a mixture of the detergent and the water is added to the barrel 80.
It is also possible to use it by cleaning the inside of the barrel 80 by putting it in the inside of the barrel and swinging and rotating the barrel 80 by the barrel swinging and rotating unit 13.
