BACKGROUND OF THE INVENTION The present invention relates to a pottery production apparatus,
In particular, the present invention relates to a pottery production apparatus for firing edible materials such as edible grains and dried fish by indirect heating. The present invention also relates to a potato production apparatus, and more particularly to a far infrared heating type potato production apparatus.

[0002]

2. Description of the Related Art For example, potatoes, chestnuts, dried squids, etc. are buried in a bonfire or hot ash as they are and baked. Such indirect baking is, for example, in the case of roasted potatoes, Satsuma potatoes are put in a closed pot containing stones, the closed pots are heated from the outside, and the Satsuma potatoes are baked on the stones. In this case, since Satsuma yam contains amylase, by slowly heating it at a temperature of 60 ° C., saccharification proceeds and sweet potato with increased sweetness can be obtained.

[0003]

[Problems to be Solved by the Invention] However, since baked potatoes are baked by contacting stones or ceramics that are heated to a high temperature, the surface of the potatoes is burnt, and it is said that they contain vitamins and the like. It is sweet and delicious because you can not eat the part and you can not eat the burnt part, but it is a problem because the yield is poor. Also,
An apparatus for producing baked potatoes by microwave heating has been proposed. However, in the case of heating by microwaves, the temperature rises rapidly and the baking takes place in a relatively short time, which causes a problem of less sweetness. The present invention aims to solve the problems regarding the sweetness and the yield of the conventional baked potato production apparatus, for example.

Embodiments of the present invention will be described below with reference to the accompanying drawings, but the present invention is not limited to the following description and examples. FIG. 1 is a schematic side sectional view for explanation, showing a part of a baked potato manufacturing apparatus of an embodiment of a baked product manufacturing apparatus according to the present invention by cutting away.

In the embodiment shown in FIG. 1, the housing 2 of the baked potato production apparatus 1 is formed of a heat insulating member, and the inside of the housing 2 has a hole having a size smaller than that of the baked potato and hot air passes therethrough. It is divided into upper and lower spaces by a heat resistant partition wall 3. The upper space is the produced greenhouse greenhouse 4 for potatoes, and the ceiling 5 is surrounded by a wire mesh 6 and is filled with a deodorant 7, and the outside is provided with an enclosure 8 such as an exhaust cover. An exhaust port 9 is formed. The space below is a baking chamber 10 for the production of baked potatoes, and a shelf support 12 for supporting a shelf plate 11 for holding the potatoes of the raw material of the baked potatoes formed of a porous member is provided on the inner wall 13. There is.

Far-infrared heating devices 14 and 15 are provided above and below the porous potato holding shelf 11 toward the shelf 11. In this example, the far-infrared heating devices 14 and 15 each have, for example, a particle size of 10 mm or more,
Preferably, far-infrared radiator support frames 16 and 17 packed with a lumped far-infrared radiation ceramic heating body having a size of 30 mm or more are provided, and a sheath heater 18 is provided behind the support frames 16 and 17, respectively. Insulation walls 19 and 20 mounted on the side are provided. The far-infrared heating devices 14 and 15 are formed in a container shape by a perforated porous member such as a net or a perforated plate so that the emitting surface and the non-heating surface of the far-infrared radiator are not covered as much as possible. There is. In this example, the far infrared heating device 14 on the upper side is formed so as to be movable in the vertical direction, and the movement is performed by a steel rope 21. Therefore, in this example, lifting hooks 23 are provided on the grips 22 at the four corners of the far infrared device 14, respectively. This lifting hook 2
One end of a steel rope 21 is attached to each of the ropes 3, and the other end of the rope is wound around a winding drum 24. In this example, a handle 25 is attached to the winding drum 24, and by manually winding the rope 21 around the winding drum, the far infrared heating device 14 located above can be moved upward. By unwinding the rope 21 wound around 24, the far-infrared heating device 14 on the upper side can be moved downward.

Since the present example is constructed as described above, the Satsuma potatoes are placed on the net-like shelf plate 11, the handle 25 is turned, and the position of the far infrared heating device 14 above is adjusted.
Adjust its heating position. The heating position of the far-infrared radiator varies depending on the amount of the far-infrared radiator and the amount of heat for heating the far-infrared radiator, and the distance between the far-infrared radiator and the potato can be, for example, 50 mm to 100 mm. The far-infrared radiator is fixed in position, electricity is passed through the sheath heater 18, and the sheath heater 18 heats a lump-shaped far-infrared radiation ceramic (not shown). The far-infrared radiation ceramic heating body increases the radiation amount of far-infrared radiation as the temperature rises, but also raises the temperature in the firing chamber 10 at its own temperature. The far-infrared radiation ceramic heater used for heating in the present invention has a heat storage property, so that, for example, the energization of the sheath heater 18 is adjusted and the amount of far-infrared radiator accommodated in the far-infrared radiator support frame is adjusted. By doing so, it is easy to adjust the firing conditions for potatoes. For example, the temperature of the upper far-infrared radiation ceramic heating element 14 is 350 to 550 ° C., and the temperature of the lower far-infrared radiation ceramic heating element 15 is 4
The temperature in the baking chamber 10 is 180 to 2
By heating at 50 ° C., for example, for 30 minutes to 50 minutes, a baked potato with a so-called 100% edible portion, which has a good finish and can be eaten entirely, is obtained. The finished baked potatoes can be placed in the greenhouse 4 and can be eaten at an appropriate time for the appropriately-heated baked potatoes. In this example, the far-infrared radiation ceramics heating body is held in the reticulated far-infrared radiation support frame 16, but a cassette containing the far-infrared radiation is formed to replace the far-infrared radiation. It can also be done by exchanging.

Example 1 30 pieces of M size gold-potato (weight 4890 g) were baked in the baking chamber 1.
The sheath heater 18 is arranged on the net-like shelf 11 in
Electricity was applied to the above to heat the upper far infrared radiation ceramic heater to a temperature of 400 ° C and the lower far infrared radiation ceramic heater to a temperature of 550 ° C. The temperature in the baking chamber 10 was 200 ° C., and the heating time was 40 minutes.
The baked potato obtained after baking was 4100 g, all of which were edible and had a good sweetness.

EXAMPLE 2 M size Beni Azuma from Ibaraki prefecture (diameter 40 to 50 mm, length 200 mm, weight 200 to 220 g) was placed on the net-like shelf plate 11 in the firing chamber 10 and electricity was supplied to the sheath heater 18. The upper far infrared radiation ceramics heating body is heated to a temperature of 350 ° C., the lower far infrared radiation ceramics heating body is heated to a temperature of 500 ° C., the temperature in the firing chamber 10 is set to 200 ° C., and the heating time is 50 minutes. did. The baked potato obtained after baking had no strong charring, and was baked soft as a whole, and had a good sweetness. Baking was performed under substantially the same conditions with a firing time of 45 minutes, but similar results were obtained.

In this example, only the far-infrared heating device having the upper far-infrared radiation ceramic heater is movable, but both far-infrared heating devices having the upper and lower far-infrared radiation ceramic heating bodies are both movable. Can be formed. In this example, the movement of the far infrared heating device is a winding method using a rope,
It is also possible to adopt a rack and pinion system so that appropriate power can be used.
