Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves arranging a large number of vein caps vertically and horizontally in a grain vat for tensioning, and while grains are flowing down between these many vein caps, the grains are removed from each vein cap. This is a conditioning device that controls the humidity and temperature of grains by supplying or exhausting air, and has improved the arrangement of the veins that supply or exhaust air.

In a conventional grain conditioning device of this kind, the vein umbrellas in the grain tank are arranged vertically and horizontally, for example in rows A to E in the vertical direction and in rows in the horizontal direction, as shown in Fig. 1.・A staggered arrangement is used with appropriate intervals for grains to flow down between each vein cap, so that the vein caps 1' in even-numbered stages are located between the vein caps 1 in odd-numbered stages, and All the striated umbrellas in the tiers are arranged for air supply, and all the striated umbrellas in even-numbered tiers are used for exhaust air.

The grains then move within the grain vat as shown by the arrow streamlines in FIG. During this vertical movement of the grain, the grain is gradually tempered by being alternately supplied with air or exhausted from each vein. For example, as shown between columns A and B, there is a tendency to flow as a rectifier between columns, and therefore, streamlines a and b on both sides of one rectifier always flow in the same column, for example, a is A.
Column b is along column B. However, since the conventional arrangement of the air supply vein umbrella and the exhaust vein umbrella is as described above, grains along streamline a receive only the air supply action, and grains along streamline b receive only the exhaust action. This causes unevenness in the refining function.

In order to avoid this, it is conceivable to use a switching valve to switch between the air supply striations and the exhaust striations at regular intervals, but this requires a switching valve and its control device, making the structure complicated.

The present invention aims to solve the above-mentioned problems, and will be explained below based on the illustrated embodiments. Fig. 2 schematically shows the entire grain conditioning device. , 1'. The striated umbrellas 1 and 1' have the same structure, only showing the odd and even stages.

A large number of vein umbrellas 1, 1' are arranged in parallel or gently inclined in the grain tank 2, vertically and horizontally, with appropriate intervals between them. The arrangement of the striated umbrellas 1' in a staggered arrangement is the same as that of the prior art.

The discharge port 4 and the supply port 3 are connected by an elevator 5, and the discharge port 4 is provided with a screw conveyor 6, and the supply port 3 is provided with a diffusion blade 7.

Now, examples of the arrangement of the air supply vein umbrella (marked with a circle) and the exhaust vein umbrella (marked with an x) in the grain conditioning apparatus of the present invention are shown in FIGS. 3 and 4.

That is, for example, in an arrangement including columns A to E and each stage of . It consists of a service vein umbrella and an exhaust vein umbrella.

Both Figures 3 and 4 are suitable for this configuration, but in the case of Figure 3, the horizontal striations (for example, A--E-) of each stage are also alternately used for air supply and exhaust. However, in Fig. 4, in the lateral direction of each stage, all the striated umbrellas are for air supply or exhaust.

FIG. 5 shows the same shape as the conventional one for reference.

One end of each vein umbrella is closed, and the other end is connected to the air supply chamber attached to the grain tank 2 for air supply, and to the exhaust port for exhaust (the air supply chamber and exhaust port are not shown in the figure). do.).

In the above configuration, when the grain tank 2 is loaded with grains as shown by the chain line and the device is operated, the grains move within the grain tank 2 by gravity and the action of the screw conveyor 6 and elevator 5. Even when the movement of grains is such that the grain flows down between the columns of the vein umbrellas as a rectification, the grain flow along both sides of the rectification is alternately affected by air supply and exhaust.

In the present invention, thermal refining means drying, heating, cooling with hot air or cold air, or humidification with humidified air.

Therefore, the present invention solves the conventional drawbacks, and provides an effect in which a less uneven refining action can be obtained in a vein-umbrella type refining device without requiring a switching valve or its control device. have
