Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for producing ponsenbei made from grains such as brown rice.

[0002]

2. Description of the Related Art A conventional ponsen rice cracker manufacturing apparatus is disclosed in Japanese Patent Publication No. 58-854. The apparatus described in this publication lowers the upper baking mold, compresses and fires a pre-treated granular raw material in an airtight baking chamber, and then opens the bottom surface of the upper baking mold to the side. It was opened by raising it to a position above the upper surface of the mold to expand the granular raw material, discharge the steam accumulated in the baking chamber, and lower the upper baking mold again to mold the pond cracker.

The above-mentioned apparatus expands the granular raw material by raising the upper baking mold from the compressed state in the airtight firing chamber. Therefore, when the airtightness in the firing chamber is not sufficient, it is planned. It was difficult to obtain a sufficient expansion force, and the thickness of the ponsenbei tended to be uneven. Therefore, in order to keep the airtightness inside the firing chamber,
Also, it is tried to improve the fitting accuracy between the side molds, but it is difficult to maintain the fitting accuracy between each baking mold because the upper baking mold and the lower baking mold are heated during the firing process. Met. Furthermore, the above-mentioned device lowers the upper baking mold again in order to mold the ponsenbei,
Since the ponsenbei in the expanded state has a non-uniform thickness, it is not possible to make the range in which the upper baking mold is lowered constant, and in reality, the ponsenbei cannot be molded with a good appearance. It was

In order to solve these problems, an apparatus as disclosed in Japanese Patent Laid-Open No. 62-6624 was developed. This device is equipped with a quick exhaust valve on the exhaust side of an air cylinder for raising and lowering the upper baking mold, and after compressing and firing the granular raw material, the bottom of the upper baking mold is placed on the upper side of the side mold. It was able to rapidly rise to a higher position. In this way, by making the rise of the upper baking mold more rapid, the expansion force of the granular raw material can be stably obtained even if the fitting accuracy between the baking molds is not sufficient. The thickness can be made almost uniform.

[0005]

However, in the above apparatus, the bottom surface of the upper baking die suddenly rises to a position higher than the upper surface of the side die, and the sudden rise of the upper baking die causes the granular raw material Although it obtains expansion power, only a few particles that are present on the surface of the expanded raw material and that adhere to the bottom surface of the upper baking mold while the upper baking mold is rapidly rising,
The surface was made uniform. Therefore, the finished ponsenbei was in a state in which the substantially granular raw material was still expanded, and the unevenness was conspicuous on the upper and lower surfaces, so that the shape was not arranged and the appearance was not very good.

[0006] Therefore, it is an object of the present invention to provide an apparatus for producing ponsenbei, which is capable of molding ponsenbei with good appearance.

[0007]

In order to achieve the above object, the present invention provides a prebaking die capable of raising and lowering a pretreated raw material, a side mold to which the prebaking die can be fitted, and a side mold. A device for manufacturing ponsenbei, which is formed in an airtight heated baking mold formed with a lower baking mold fitted to a mold, which rapidly raises the upper baking mold and causes the upper baking mold to rise rapidly. The purpose of the present invention is to provide a ponsenbei manufacturing apparatus characterized in that it is equipped with a control unit that controls to stop once in the middle of the process so that steam in the firing chamber can be discharged.

[0008]

According to the present invention, the granular raw material is compressed and fired in the firing chamber formed by the upper firing die, the side die and the lower firing die, and then the upper firing die is rapidly raised and the upper firing die is rapidly raised. By controlling to stop once in the middle, the upper baking mold can be temporarily stopped in the side mold, and the granular raw material is rapidly expanded by the first rise, and at the position that is the upper limit of the expansion, By temporarily stopping the upper baking mold, the ponsenbei can be molded. Then, as the tip of the upper baking mold rises to a position above the upper surface of the side mold by the second rise, it becomes possible to take out the ponsenbei. Here, when the upper baking mold is temporarily stopped, the upper baking mold exists in the side mold, and the baking chamber is airtight due to the upper baking mold, the side mold, and the lower baking mold. , Steam generated from Ponsenbei will stay. With this, the steam generated from the ponsenbei penetrates between the particles, and good molding cannot be performed. Therefore, by providing a control unit that allows the steam in the firing chamber to be discharged when the upper baking mold is temporarily stopped in the side mold, the steam accumulated in the baking chamber can be smoothly discharged, and In that case, the bubbles remaining between the expanded particles can be discharged to the outside, so that a pond rice cracker with a good appearance and no unevenness on the surface of the pond rice cracker is completed.

The raw material A is supplied from the raw material supply unit 4 onto the lower baking dies 7 (FIG. 1). The upper and lower baking molds 6 and 7 are preheated by a built-in heater 19 (FIG. 2) so that the raw material A can be baked. At this time, the upper baking die 6 is stopped at the upper limit by supplying compressed air to the head side 15a of the upper baking die air cylinder 15 (FIG. 2).
This state is the state of the upper baking mold 6 and the lower baking mold 7 before the compression step of the raw material A.

Next, the step of compressing the raw material A will be described. FIG.
As shown in FIG. 3, the compressed air supplied from the air pressure source 30 is cleaned by the filter 31, and the high-pressure compressed air whose pressure is adjusted by the relief valve 32 is supplied to the solenoid valve 39. The solenoid valve 39 is
It is in the lower position 39b. The compressed air supplied to the inlet side 39c of the solenoid valve 39 tends to flow to the outlet side 39d, but the outlet side 39d is blocked. On the other hand, compressed air whose pressure is adjusted by the relief valve 33 is supplied to the solenoid valve 34. The solenoid valve 34 is in the lower position 34b. The compressed air supplied to the inlet side 34c of the solenoid valve 34 flows to the outlet side 34d. Outlet side 3 of solenoid valve 34
Since 4d is connected to the head side 15a of the top baking die air cylinder 15, compressed air is supplied to the head side 15a of the top baking die air cylinder 15. The rod side 15b of the air cylinder 15 for baking metal is connected to the outlet side 41b of the quick exhaust valve 41, so that compressed air is supplied to the head side 15a of the air cylinder 15 for baking metal, and at the same time, the air is burned out. Rod side of mold air cylinder 15 1
The compressed air filled in 5b is rapidly exhausted directly from the exhaust side 41c of the quick exhaust valve 41 to the atmosphere. As a result, compressed air is supplied from the head side 15a to the burnout die air cylinder 15, and at the same time, the compressed air filled in the rod side 15b is exhausted, and the inside of the burnout die air cylinder 15 is discharged. The piston 35 moves up. Then, the upper baking dies 6 interlocked with the piston 35 rises rapidly and stops at the upper limit. FIG. 3 is a diagram showing a state in which the upper baking die 6 is lifted.

Next, from the state shown in FIG. 3, the solenoid valve 34 is moved to the upper position 34 by a control signal from the controller 8.
Switch to a. Compressed air whose pressure is adjusted by the relief valve 33 is supplied to the inlet side 34 g of the solenoid valve 34.
To the outlet side 34h, and from the outlet side 34h to the inlet side 40a of the quick exhaust valve 40. The compressed air supplied from the inlet side 40a flows to the outlet side 40b and flows to the inlet side 41a of the quick exhaust valve 41. Inlet side 41 of quick exhaust valve 41
The compressed air supplied from a flows to the outlet side 41b, and is supplied to the rod side 15b of the air cylinder 15 for baking furnace. At the same time that compressed air is supplied to the rod side 15b of the burning cylinder for air-cooling die 15, the compressed air filled in the head side 15a of the air cylinder for burning-die 15 passes through the inlet side 34i of the solenoid valve 34. The air is exhausted to the outside air from the outlet side 34j. As a result, compressed air is supplied from the rod side 15b to the burnout die air cylinder 15, and at the same time, the compressed air filled in the rod side 15a is exhausted, so that the burnout die air cylinder 15 inside Piston 3
5 descends. And the firing mold 6 that works with the piston 35
Descends and is fitted into the side mold 10. And the baking mold 6
Is lowered to a certain position, the piston 35 comes into contact with the limit switch 36 to stop the piston 35, and the timer 37 is started to set the raw material A by the upper baking mold 6 and the lower baking mold 7 for the set time of the timer 37. Compress and fire. At this time, although the upper baking mold 6 and the side mold 10 are fitted to each other, an annular gap a is formed between the upper baking mold 6 and the inner side surface 10b of the side mold 10 due to the notch 17 provided in the upper baking mold 6. Since the upper part of the upper baking mold 6 above the notch 17 is tightly fitted to the inner side surface 10b of the side mold 10, the baking chamber can be kept airtight. This state is shown in Figure 4.
It becomes as shown in.

Next, the expansion and molding process of the raw material A will be described. Simultaneously with the elapse of the set time of the timer 37, the solenoid valve 34 switches to the lower position 34b. Compressed air is supplied to the inlet side 34c of the solenoid valve 34,
It flows to the outlet side 34d. Then, it is supplied from the outlet side 34d to the head side 15a of the air cylinder 15 for the baking finish type. At the same time as compressed air is supplied to the head side 15a,
The compressed air filling the rod side 15b is rapidly exhausted directly to the atmosphere from the exhaust side 41c of the quick exhaust valve 41. As a result, compressed air is supplied from the head side 15a to the burnout die air cylinder 15, and at the same time, the compressed air filled in the rod side 15b is exhausted, and the inside of the burnout die air cylinder 15 is discharged. Piston 3
5 rises, and the upper baking die 6 that interlocks with the piston 35 rises sharply. Then, the raw material A in the baking mold expands while the upper baking mold 6 rapidly rises. At this time, the solenoid valve 39
Is in the lower position 39b, and the compressed air from the relief valve 32 is still blocked at the outlet side 39d of the solenoid valve 39.

Still further, the upper baking die 6 rapidly rises, and as shown in FIG. 5, the upper end portion 17 of the cutout portion 17 provided in the upper baking die 6 is increased.
When a rises above the upper surface 10a of the side mold 10, the piston 35 contacts the limit switch 38, and the solenoid valve 39 switches to the upper position 39a. Thereby, the flow direction of the compressed air from the relief valve 32 is switched, and the compressed air having a pressure higher than the pressure set by the relief valve 33 flows from the inlet side 39g of the solenoid valve 39 to the outlet side 39h. Then, it flows from the exhaust side 40c of the quick exhaust valve 40 to the outlet side 40b. Furthermore, the quick exhaust valve 41 flows from the inlet side 41a to the outlet side 41b. At this time, since the solenoid valve 34 is located at the lower position 34b on the outlet side 41b of the quick exhaust valve 41, the rod side 15b of the upper baking die air cylinder 15 is formed.
Although the compressed air is exhausted from the exhaust side 41c of the quick exhaust valve 41, the compressed air is supplied from the inlet side 41a to the outlet side 41b of the quick exhaust valve 41. To do. Since the compressed air at this time is set by the relief valve 32 and is higher than the pressure set by the relief valve 33, the burning cylinder air cylinder 1
5 can be stopped suddenly at a stable position. Therefore,
The head side air cylinder 15 is temporarily attached to the head side 1
Since the compressed air is supplied from both the direction of 5a and the rod side 15b, the piston 35 is temporarily stopped during the ascent, and the interlocking firing mold 6 can be temporarily stopped. At this time, once the upper baking die 6 is stopped, the expansion force of the raw material A causes the bottom surface 6b of the upper baking die 6 and the inner surface 1 of the side die 10 to move.
0b and the upper surface 7b of the lower baking mold 7 block. Then, since the upper and lower baking molds 6 and 7 are heated by the heater 19, the upper and lower surfaces of the raw material A are baked, and the ponsenbei B having no unevenness on the surface is molded. Furthermore, the notch 17 and the side mold 10 are provided by the notch 17 provided in the upper baking mold 6.
An annular gap b opened upward from the inner surface 10b of the
Since it is possible to communicate with the outside air, the vapor accumulated in the firing chamber can be smoothly discharged, and the bubbles remaining between the expanded particles can be discharged to the outside.

In this way, after the pom cracker B is molded, the solenoid valve 39 is switched to the lower position 39b by the control signal from the control unit 8 and supplied from the inlet side 39c of the solenoid valve 39. The compressed air is cut off at the outlet side 39d, and the solenoid valve 39 is supplied from the inlet side 41a of the quick exhaust valve 41.
The compressed air in the pipe up to the inlet side 39e of the
Exhausted through f. As a result, the inflow of compressed air from the rod side 15b of the combustion cylinder air cylinder 15 to the outlet side 41b of the quick exhaust valve 41 is restarted, and the compressed air that has flowed in from the outlet side 41b of the quick exhaust valve 41 is replaced by the quick exhaust gas. Valve 4
Flow to the exhaust side 41c of 1, and is rapidly exhausted directly to the atmosphere,
The cylinder 15 for upper baking mold will suddenly rise again,
The interbaking die 6 can be rapidly raised again. Then, as shown in FIG. 6, the upper baking mold 6 is the upper surface 1 of the side mold 10.
Stop above 0a. Next, the formed ponsenbei B is placed, the lower baking mold 7 rises and stops, and the ponsenbei B is taken out.

In this embodiment, the upper and lower baking molds 6 and 7 have the heater 19 built therein for baking the raw material A. However, the side mold 10 to which the upper and lower baking molds 6 and 7 are fitted has a temperature. It is considered that better molding is possible by applying control.

Needless to say, various embodiments can be adopted without departing from the scope of the present invention. In the present embodiment, the notch 17 provided in the upper baking die 6 is the upper baking die 6
Is provided on the entire circumference from the lower end of the mold to the vicinity of the middle part,
The inner surface 10b of the No. 3 is loosely fitted, but if the steam accumulated in the firing chamber can be smoothly discharged,
It does not matter what shape it is, and if the steam retained in the firing chamber can be discharged to the outside when the upper firing mold 6 is once stopped, it can be provided in the lower firing mold 7.
Since it is possible to provide both in the upper baking mold 6 and the lower baking mold 7, the position is not limited.

Further, in this embodiment, the upper and lower baking molds 6 and 7 are cylindrical, and the side mold 10 is cylindrical. However, the upper and lower baking molds 6 and 7 may have various shapes such as a square shape. It is, of course, possible to change the shape of the side mold 10 into a shape that can be fitted to the upper and lower baking molds 6 and 7.
