Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an immersion tank for cereals such as soybeans, red beans, rice and wheat. The immersion tank in the present invention means a vertical type. [0002] Early immersion tanks do not have a tray between the inlet and the outlet, and generally take a long time to drain, so that the drainage time between the upper and lower layers of the immersed grain is greatly different. There was a problem that occurred. This problem of drainage is particularly prominent in grains that swell after water absorption. In particular, when the purpose is limited water absorption, local variations in the water absorbed cannot be avoided. To solve these problems,
The installation of trays has been devised, and soaking tanks with various trays have been developed. The immersion tank (Japanese Utility Model No. 2-39557) of the prior application is
An inlet is provided at the upper part and an outlet is provided at the lower part. A tiltable receiving shelf is provided between the inlet and the outlet in the tank. Grains are first pre-soaked in the upper part of the receiving shelf, and after swelling, the receiving shelf is tilted and opened, and the cereal is dropped into the lower part of the receiving shelf together with water to be filled and the swelling pressure is dispersed. In this way, complete immersion while maintaining the shape of the grains became possible. [0004] The immersion tank provided with such a receiving shelf can reduce the drainage time, tilt the receiving shelf,
In addition to the advantage of releasing the cereals that have been opened and agglomerated by water absorption to make them difficult to discharge, they have the disadvantage that they are discharged while breaking down, and that the degree of drainage in the lower layer of the raw material is poor and a large amount of excess water remains. [0005] The disadvantage of poor drainage is a cause of uneven water absorption of cereals, especially when there is a requirement for limited water absorption. For example, in the case of making koji by immersing rice in sake production, In addition, the quality of koji is significantly reduced. Therefore, in the immersion tank,
In order to remove the drawbacks seen in the above while taking advantage of the above, an attempt was made to study the structure of the tank. [0006] As a result of the study, what has been developed is provided with an inlet at the upper part of the tank for immersing cereals in water or the like, and a discharge port at the lower part. A immersion tank provided with a receiving shelf having a downward opening mechanism therebetween, wherein the receiving shelf is inclined when draining or draining the water. [0007] The receiving shelf is composed of a plurality of flat plates symmetrical with respect to the central axis in the longitudinal direction of the tank, and the flat plates may be combined in a chevron or valley toward the central axis. The angle of inclination is 5 to 45 degrees, preferably 10 to 30 degrees. In a receiving shelf in which flat plates are combined in a mountain shape, each flat plate provided with a horizontal rotation axis near the vertex rotates downward from the outer periphery to open the receiving shelf. In the receiving shelf in which the flat plates are combined in a valley shape, each flat plate provided with a horizontal rotation axis near the outer periphery rotates downward from the top to open the receiving shelf. [0008] The opening mechanism can be realized by a method of using a rotating shaft rotated by the power of a deceleration motor or the like, or a method of lifting and lowering a receiving shelf using a rotating shaft to which no power is applied with a wire. Note that the receiving shelf does not need to be always inclined at the time of immersion. For example, when immersing the raw material, the horizontal receiving shelf is set to the above-mentioned mountain-shaped or valley-shaped inclined state only at the time of drainage and draining, and is opened at the time of discharging the raw material. You may do so. The immersion tank for cereals of the present invention is provided with a sloping tray for supporting cereals to be immersed in water or the like, so that water remaining in the cereals at the time of discharging water or draining cereals is provided. Can flow down according to the inclination of the receiving shelf, so that the degree of draining of cereals can be improved. If the inclination angle of the receiving shelf is 5 degrees or less at the time of draining or draining, it will not change from a flat surface,
The function of draining can not be demonstrated. Also, the tilt angle of the tray is 45
When the temperature is higher than that, the ratio of receiving trays in the immersion tank increases and the volumetric efficiency decreases. In addition, the grain thickness becomes locally largely different, which may cause uneven water absorption of the grains. Because of this, the inclination angle is within 5 to 45 degrees,
Preferably it is 10 to 30 degrees. An embodiment of the immersion tank according to the present invention will be described below with reference to the drawings. FIG. 1 shows a cylindrical tank 3 having an inlet 1 at an upper portion and an outlet 2 at a lower portion, and a mountain-shaped receiving shelf 5 in which semicircular flat plates 4 and 4 are joined to each other at a straight portion. A deceleration motor 6 near the top of the tray
FIG. 2 is a vertical sectional view of an immersion tank provided with rotating shafts 7 and 7 driven in conjunction with each other as an opening mechanism, and FIG. 2 is a sectional view of the immersion tank taken along line AA in FIG. In this embodiment, as seen in FIG.
The receiving shelf 5 is opened by the plane plates 4 rotating downward from the outer periphery. Therefore, the tank lower surface 8
It is formed in an arc shape along the rotating flat plate 4. The rotating shafts 7 provided on the flat plate 4 are rotated in opposite directions by a single deceleration motor 6. After the receiving shelf 5 is opened, the cereals can be taken out without agglomerating by making the flat plates 4, 4 stand upright in parallel. As the immersion tank for making the receiving shelf 5 a chevron, a rectangular tank 9 as shown in FIG. 3 is used in addition to the cylindrical tank 3 as shown in FIG.
The receiving shelf 11 can be configured by combining 0 and 10 in a chevron.
When the trays combined in a chevron shape are opened, the flat plate is rotated so as to move away from the side of the tank, so that the tray shape can be determined according to an arbitrary tank shape. In the immersion tank having this chevron-shaped receiving shelf, the result of measuring the degree of drainage when the angle of inclination of the chevron is set to 20 degrees is shown. The measurement was carried out by immersing rice with a polishing rate of 50% in water, draining the water after 8 minutes and 30 seconds, and measuring the water content of six samples randomly extracted from the rice after one hour. The results are 29.9%, 30.2%,
29.9%, 30.0%, 29.8% and 30.2%, the average is 30.0%,
The standard deviation was 0.2%. When the same immersion is performed in the conventional immersion tank, the unevenness of water having a standard deviation of 2 to 3% occurs, which indicates that the immersion tank of the present invention is very excellent. The immersion tank of the present invention can be realized by forming the receiving shelf in a mountain shape or in a valley shape. FIG. 4 shows a prismatic tank 14 having an inlet 12 at the top and an outlet 13 at the bottom,
A valley-shaped receiving shelf 16 in which rectangular flat plates 15, 15 are joined by a straight line portion is arranged, and rotating shafts 18, 18 driven in conjunction with a speed reduction motor 17 near the outer periphery of the receiving shelf of the flat plate 15 are opened mechanisms. FIG. 5 is a vertical sectional view of the immersion tank provided as FIG. In the immersion tank having a trough-shaped receiving shelf, when the receiving shelf is opened, the flat plate is rotated so as to approach the side of the tank. Must have parallel side edges or sides,
A cylindrical tank as described above cannot be used.
However, even if the receiving shelf is divided into three or more parts, the receiving shelf can be opened without causing the respective flat plates to interfere with each other, so that the receiving shelf composed of a plurality of flat plates can be configured, and the load applied to each flat plate can be reduced. There is. According to the present invention, a large amount of cereal is soaked,
This makes it possible to use a vertical immersion tank that can easily discharge water and grains, has a short draining time, and has a good draining degree. The immersion tank can realize uniform drainage by immersion for a short time even when immersing a raw material that requires limited water absorption, thereby improving the quality of the product.
