By connecting steam introducing pipes 10, 11, 12, 13 to each of the steaming cylinders 4, 5, 6, 7 and the rotary cylinder 9 for discharging steam from the steam discharge pipes 4a, 5a, 6a, 7a, 9a. Are known.

[0003]

In the above-described conventionally known vertical steamer, first, the rice cracker raw material such as sticky rice is put into the first stage steaming cylinder 4 at the lowermost stage, and the steam outlets 4a are provided. After the steam is blown out from the steam generators 9a and 9a, the rice cracker raw material is thrown into the second-stage steaming cylinder 5, and the steam is newly blown out from the steam discharge holes 5a, which are sequentially transferred to the upper steaming cylinders 6 and 7. Repeat, about 30
After a lapse of minutes, the scraping blade 2 is rotated to take out the steamed rice cake raw material from the chute 14. However, since the rice cracker raw material is of the top stacking type, the amount scraped out by the scraping blade 2 descends by its own weight, and the rice cracker raw material is supplied from the hopper as much as the scratched blade so that it is steamed. Because the rice cracker ingredients (especially rice cake rice) that expand due to intimate contact with each other, the passage of steam required for steaming disappears, and furthermore, the steam tends to concentrate only around the steam outlets 4a to 7a, 9a. Since uniform steaming is difficult and uneven steaming occurs as a result, there is a problem that the finished rice cake has unevenness in drying and baking, and a rice cake of uniform quality cannot be obtained.

An object of the present invention is to provide a vertical steaming machine for rice cracker raw materials which is devised so that the above-mentioned steaming unevenness does not occur as much as possible.

In this case, according to the present invention, the inside of the rotary cylinder is divided into a plurality of parts in the axial direction to form a plurality of vapor introducing chambers, and the spiral blades are made hollow to form a plurality of independent plates via partition plates. It is possible to provide the above-mentioned vapor reservoir chambers and to communicate these vapor reservoir chambers with the vapor insertion chambers of the rotary cylinder.

According to the present invention, one end side of a steam distribution pipe is connected to each steam introducing chamber formed in the inner axial direction of the rotary cylinder, and steam having different pressure is supplied to each steam introducing chamber. In addition to being configured so that it can be introduced, the other end side of each steam distribution pipe can be connected to a steam collection pipe, and this steam collection pipe can be connected to the main steam distribution pipe via a movable joint pipe. .

Further, according to the present invention, a cover for preventing clogging is provided in the steam outlet hole provided in the spiral blade, and the main steam flow pipe and each steam distribution pipe are provided in a lower part or an upper part of the rotary cylinder. Can be provided.

Further, the present invention is such that the pitch of the spiral blade becomes wider toward the lower part, or the steaming cylinder is configured such that the inner diameter becomes wider toward the lower part, and The steam blowout holes may be provided in the inner wall or the inner wall of the steaming cylinder and the rotary cylinder and / or the spiral blade.

In the other embodiment of No. 6, the feed screw is not installed. The hopper may be configured in this way.

The operation method of the vertical steaming machine for rice crackers according to the present invention will be described below. Hopper 46
Rice cake and rice cake powder are used as the rice cracker raw materials to be added to, but the case of using rice cake rice will be described. First, the steaming cylinder 22 is divided into four parts including the raw material charging chamber 23, the lowermost part is made into the first steaming cylinder part, and the second to fourth steaming cylinder parts are sequentially arranged in the upper direction. Next, the steamed rice that has been sufficiently hydrated is fed from the hopper 46 using the screw 46a until the first steaming tube is filled up, and steam distribution pipe 28 for sending steam to the first steaming tube is used. The stop valve 32 is opened.

Next, the sticky rice is put into the second steaming tube, and the stop valve 32 of the steam distribution pipe 28 for sending steam to the second steaming tube is opened. Similarly, the sticky rice is also fed to the third steaming tube. To open the stop valve 32 of the steam distribution pipe 28 for sending steam to the third steam-cylinder portion.
Although sticky rice is put into the steaming cylinder, steam is generally not blown into the fourth steaming cylinder, but steam coming from the bottom is used in many cases. Of course, steam may be blown in.

About 2.5 bales of sticky rice can be put into the steaming cylinder 22 and discharged from the take-out chute 40 in about 30 minutes. The inside of the rotary cylinder 24 is axially divided into four by a partition plate 24a to form a steam introduction chamber 24b, and the steam having different pressures is supplied to the respective steam introduction chambers 24b through the steam distribution pipes 28. The pressure is set via the pressure reducing valve 30 so that the pressure becomes weaker as it goes up from the first steaming cylinder portion. The steamed rice cake thus steamed is discharged to the take-out chute 40 when the take-out door 39 is opened and the rotary cylinder 24 is rotated. In the above operation, it is optional to eject the steam from the steam outlet 22c provided in the inner wall 22a of the steaming cylinder 22.

The shaft support means 56 of the rotary cylinder 53 is
It is attached to the gantry 58 side. The reference symbol 59 is a drain discharge pipe. The other same reference symbols represent the same members as those in FIG.

The operation method of the vertical steamer according to this embodiment is almost the same as that of the previous embodiment, and the explanation thereof is omitted because it is understood by looking at the drawings. To do.

[0019]

According to the present invention, the weight of the steamed sticky rice is supported because the rice cake raw material, especially sticky rice, which has been put into the steaming cylinder is supported by the spiral blades by dispersing its weight. As a result, the sticky rice in the lower part of the steaming cylinder (first steaming cylinder) will not be crushed, and the steam blown out from the steam outlet holes provided in the spiral blade will be drawn by the steam discharge blower and spirally wound. Since the rice cake passes through the rice cake-like rice likewise, it is possible to obtain an effect that steam can be spread evenly and steam unevenness can be prevented. Further, when the steamed sticky rice is discharged, the spiral blade is rotated to enable smooth discharge.

According to the second and third aspects of the invention, uneven steaming is caused by blowing out steams having different pressures through the steam distribution pipes connected to the vertically divided parts of the steaming cylinder. Can be prevented as much as possible.

According to the fourth and fifth aspects of the invention, it is possible to prevent the steamed sticky rice from being pressed by the pressure and blocking the steam blowout holes provided especially on the upper surface of the spiral blade. It is possible.

According to the sixth and seventh aspects, it is possible to promote the smooth fall of the steamed sticky rice in the steaming cylinder.
