Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a method for efficiently gelatinizing starch grains by steaming rice, wheat, and other raw material grains, and for obtaining high-quality products. This invention relates to a continuous processing device for grains.

[Conventional technology]

As a device of this type, one is known in which a horizontal primary steamer is placed directly below a tank that stores raw grains, and a horizontal secondary steamer is placed in front of it (for example, in Japanese Patent Laid-Open No. 60 (Refer to Publication No.-12945). and,
In this horizontal flossing device, the grains are passed through by a conveying means over a predetermined period of time, during which time steam is supplied.

[Problem to be solved by the invention]

Thus – if both the secondary and secondary steaming devices are horizontal,
It is not possible to take a sufficiently long time for the raw material grains to pass through this area by means of the conveyance means, and it is not possible to supply steam to the grains for a long period of time during this time. In other words, it is not possible to steam the grains to an ideal state, and at least gelatinization by the primary steaming process is impossible.

Furthermore, if both the secondary and secondary steaming devices are horizontal, it is necessary to take a certain amount of time to supply steam to the grains transported by the transporting means, so the transporting means and the steaming equipment are horizontal. This has the disadvantage that the length of the process is unavoidable, and the device as a whole becomes large.

The present invention aims to eliminate these drawbacks.

[Means to solve the problem]

To achieve this objective, the present invention provides a hopper-like vertical primary steaming device that can supply steam to soaked raw material grains, and a horizontal secondary steaming device that can further supply steam to the primary steamed grains. The steaming device is arranged continuously at right angles to the steaming device. In this case, the hopper of the vertical primary steaming device can be divided into at least two parts, upper and lower, and the lower hopper (1f) is mounted on a cart (7) that is movable with respect to the machine body (6). is preferable.

In addition, at least one of the pair of left and right side plates that are part of the horizontal secondary steaming device is opened outward around a horizontal hinge shaft 01Il that is arranged parallel to the conveying direction of the primary steamed grains. It is preferable to make it possible. On the other hand, this side plate has double walls, inside and outside, and a gap is provided between both walls to open the upper end of this space O1, while an outlet (2φ is preferably provided) at the lower end.

Furthermore, the steam room (2a
Preferably, a further steam chamber (23) is arranged at the bottom of the steam chamber (23).

In this case, in the steam chamber (23), it is preferable to form a continuous passage (23a) like a rectangular wave in a plane.

Note that it is preferable to provide a shower device Oe at an appropriate location in the lower part of the vertical primary steaming device.

[For production]

The soaked raw material grains are introduced into a hopper-shaped vertical primary steaming device (11) from above in Figure 1.2, and are allowed to stay there for a predetermined period of time, during which time they are steamed by steam (
primary steaming). During this time, grain starch can be gelatinized.

Next, the primary steamed grains fall naturally by gravity from the lower end of the primary steaming device (11), and further reach the secondary steaming device (2) which is continuous with this.Then, it takes a predetermined time to pass through here. In the meantime, it is further steamed (secondary steaming), and finally, the ideal product number of high quality, which is completely gelatinized in the center of the grain, can be taken out.

In this case, as in the invention set forth in claim 2, the hopper of the vertical primary rattanning device (1) can be divided into at least two upper and lower parts, and the lower hopper (1f) is connected to the machine body (6). If it is mounted on a movable trolley (7), the lower hopper (1f) is pulled together with the trolley (7) as shown by the chain line in Figure 6, with the upper hopper (1e) slightly floating. Since it can be removed, it is convenient when cleaning the hopper.

In addition, as in the invention as claimed in claim 3, at least one of the pair of left and right side plates that are part of the horizontal secondary steaming device is provided with a horizontal plate arranged parallel to the conveyance direction of the primary steamed grains. If it is designed so that it can be opened outward around the hinge axis 0, the side plate (2b) standing vertically can be opened outward as shown by the chain line in Figure 8 during the secondary steaming operation. This makes it convenient for inspection, cleaning, etc. On the other hand, this side plate (2b) has double walls, inside and outside, as in the invention set forth in claim 4, and a space is provided between both walls to open the upper end of this space 09+, while the lower end thereof is drained. Providing an outlet QΦ (FIG. 8) not only provides an excellent heat retention effect due to the double wall structure, but also reduces dew condensation.

The biggest advantage in this case is that during the secondary steaming process, a large amount of water droplets adhering to the upper cover (2C) flow down the wall and into the space α$ of the side plate (2b), allowing the water to flow through the outlet Q. It flows naturally from the.

Furthermore, as in the invention described in claim 5, another steam chamber (23
) (Figures 8 and 9), the steam in the steam chamber (2a) used for secondary steaming is transferred to another steam chamber (2a) at the bottom.
23) The steam inside the grains further heats the grains, allowing for more ideal secondary steaming that can sufficiently remove moisture from the surface of the grains. In this case, as in the invention described in claim 6, the passage (23) that continues like a rectangular wave in the steam chamber (23).
a) (Fig. 9), the steam sent from the inlet in the direction of the arrow in the figure will pass through a rectangular wave-shaped passage (23a).
The gas passes through the steam chamber (23) and evenly reaches every corner of the steam chamber (23), and is eventually discharged from the outlet in the direction of the arrow in the figure.

In addition, if the shower device αQ is provided at an appropriate location in the lower part of the vertical primary steaming device as in the invention described in claim 7 (FIGS. 1 and 7), the grains to be processed can be If necessary, cold water or hot water can be sprayed from the shower device Oe toward the grains that have been primarily steamed depending on the nature of the grains or the state of the primary bush.

It is mounted on a possible trolley (7). In order to make the trolley (7) movable relative to the aircraft body (6), for example, the trolley (
Place the rear part (left side in Figures 1 and 6) of 7) on four rotatable rollers (8) fixed to the body (6) side, and also fixed to the front side of the trolley (7). This can be done by allowing another rotatable roller (9) [Fig. 6] to run under the rail (not shown) of the fuselage +11 (19), but this method is limited to this. It is not something that will be done. Then, when this trolley (7) is pulled out from the position shown by the solid line in Figure 6 as shown by the chain line in Figure 6, only the lower hopper (1f) can be moved while the upper hopper (1e) remains the same. . This is convenient when cleaning the hopper. Before pulling out the trolley (7), lift the upper hopper (1e) slightly in advance. Although the means for doing so is not shown, this is possible by attaching a simple lifting device to the hopper.

Please note that the upper hopper can be divided into at least two parts (upper and lower).
1e) and the lower hopper (1f), a removable partition plate αω is arranged.

Figure 6 shows the hopper pulled out, but when the raw material grains immersed in the hopper of the primary steamer (1) are retained for primary steaming, the partitions are used as shown by the arrows in Figure 6. Insert plate a to the position indicated by the chain line in the figure. Then, a bottom is formed in the upper hopper (1e), and the raw material grains immersed therein can be retained. When inserting and removing the partition plate α, for example, as shown in the embodiment, the partition plate 0

It is best to rotate it. However, this method also has a partition plate αe
This is an example of how to insert and remove the , and is not limited to this.

A rotating body 0 called a crusher is arranged in the lower hopper (1e). This rotary body a rotates in the direction of the arrow in Fig. 6, and smoothes a large amount of grains that have been primarily steamed and dropped onto the net conveyor (3) (for example,
This is to maintain a constant deposition amount (to a height of about 10 to 15 cm).

In addition, in order to rotate the rotating body a) in the direction of the arrow in Fig. 6,
For example, this can be done by transmitting the rotational force of the motor shown by 04 in FIGS. 1 and 3 to the rotary body through the chain (151).

On the other hand, in the lower hopper (1f), this rotating body α
It is advisable to provide a shower device Q61, which is schematically indicated by a chain line in FIGS. 1 and 7, diagonally above Shu. This shower device Ql is capable of spouting cold water (approximately 15 to 20°C) or hot water (approximately 80°C), and is placed on the net conveyor (3) depending on the nature of the grain to be processed or the primary steaming situation. If necessary, the primary steamed grains can be rehydrated by pouring cold or hot water on them.

Next, the horizontal secondary steaming device (2) is shown in Figure 3 (2).
The left and right steam chambers shown in a) consist of six empty chambers, and the left and right sides of each steam chamber located in front of the vertical primary steaming device (1) as shown in Figures 7 and 8. It consists of a pair of left and right side plates (2b) erected to surround the left and right side plates, and a cover (2C) that covers the upper side of the both side plates (2b) and (2b). Above each steam chamber located forward of the primary steaming device (11) are a pair of left and right side plates (2b), (
2b) and a cover (2c) placed over it, forming one large chamber (2d) (Fig. 8). A steam supply pipe (2e) is arranged in each steam room (2a) so as to cross it, and each steam supply pipe (2e) has one pipe (2e) located outside the steam room (2a). 2f) Grass is supplied from (Fig. 1, Fig. 7). In Fig. 1 and Fig. 7, (
The pipes shown in 2g) are the steam chambers (
2a) and a condensate discharge pipe connected to the chamber αη which is at the same height as each steam chamber (2a) and directly below the primary steaming device (11), and the condensate discharged through each pipe (2g). are collected in one pipe (2h).The net conveyor (3), which is a means of conveying the primary steamed grains, is located in each steam room (2a) and its rear side. Steaming device (6th room located directly above chamber αη located directly under 11

By doing so, since the side +Ji (2b) is double-walled, not only is the heat retention effect excellent, but also the phenomenon of condensation inside the chamber (2d) is reduced. Therefore, the biggest advantage in this case is that during the secondary return operation, a large amount of water droplets adhering to the cover (2c) located above will flow down the wall and into the space Q9 of the side plate (2b). This means that it flows out naturally from the outlet QΦ.

On the other hand, although six steam chambers (2a) are provided in the embodiment, they may be combined into one.
If a plurality of steam chambers are combined into one, there may be a situation where the thermal efficiency of the steam is lowered compared to a case where a plurality of steam chambers are arranged side by side, but there is no problem in doing so if it can be solved. In addition, in FIG. 7, (27) represents the two adjacent steam chambers (2a), which span the two steam chambers (2a), and the inspection openings that are each formed scientifically. As shown in Part 8, the pipe (2e) for supplying air to the steam chamber (2a) has many holes (21) on alternate sides, such as on the 1000-I side and on the opposite side. Moreover, the name tag 21) is shown in Figure 10 (a), (b
As shown by j, it is bored diagonally downward at 45 degrees. Therefore, the steam ejected from the name tag (21) is ejected diagonally 45 degrees downward, and the steam is ejected from the bottom (22) of the steam chamber (2a).
