DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the hot water soaking apparatus of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view showing an embodiment of a hot water soaking apparatus according to the present invention, FIG. 2 (a) is a schematic plan view of a hot water soaking tank, and FIG. 1 (b) is a schematic cross section taken along line AA of FIG. FIG.

The hot water soaking tank is provided with a box-shaped hot water tank 1 having an open upper surface for immersing seeds in hot water at a predetermined temperature, and a hot water tank adjusted to a predetermined temperature. And a seed storage container 9 which is composed of four storage baskets 8 supported by a frame 7 with a gap therebetween, and which can be taken in and out of the hot water tank 1.

The seed storage container 9 has four storage baskets 8 made of a wire mesh, a perforated plate or the like supported by the frame 7 with a gap therebetween, and the seed storage container 9 and the side wall of the hot water tank 1 are connected to each other. Are set to have a gap between them. However, the number of storage baskets is not limited to this, and it is needless to say that the number of storage baskets can be changed to an arbitrary number as needed, or each storage basket can be removably provided on the frame.

The hot water tank 1 is provided with four terminals for simultaneously discharging hot water of a predetermined temperature supplied from the water heater 2 from the vicinity of one of the side walls facing each other to the other side wall. A supply pipe 4 having a discharge port 5 is provided along the one side wall, and a substantially central portion of the supply pipe 4 is connected to the water heater 2 via the introduction pipe 3. Further, the hot water tank 1 is provided with a discharge pipe 6 having a discharge port 6a for discharging hot water from a portion near the bottom at a substantially central portion. Therefore, the hot water supplied to the hot water tank 1 flows from the vicinity of one side wall toward the other side wall.

In this embodiment, the supply pipe 4 is provided with four discharge ports 5, but the number of discharge ports provided in the supply pipe can be changed to any number as necessary.

As shown in FIG. 1, the hot water immersion apparatus according to the present invention has hot water immersion tanks 20, 30 and a cold water tank 40 arranged on the same plane. A traveling crane device 50 for suspending and transporting the seed paddy storage container while taking it in and out of the container 40 is provided for the container 40.

That is, the traveling crane device 50 is supported by a column 51 and extends over the hot water immersion tanks 20 and 30 and the cold water tank 40, and a guide rail 52 guided by the guide rail 52. , 30 and the cold water tank 40 are provided with a self-propelled crane 53, and the hook 54 of the self-propelled crane 53 is attached to the seed storage container 9.

It is suspended by a crane 53, transported to the hot water soaking tank 20 for pre-soaking, and immersed in hot water at 48 to 49 ° C for 1 to 2 minutes.

After the above, the seed rice storage container 9 is lifted from the hot water soaking tank 20 for pre-soaking by the self-propelled crane 53, transported onto the hot water soaking tank 30 for soaking, and immersed in hot water of 51 ° C. for 15 minutes. .

After the above, the seed rice storage container 9 is pulled up from the hot water soaking tank 30 for sowing by the self-propelled crane 53, transported to the cold water tank 40, and immersed in cold water of 20 ° C. or lower to be cooled.

(In the case of hot water soaking method) A hot water soaking tank 30 for soaking is placed in
Hot water whose temperature has been adjusted to 57 ° C. is supplied, and the cold water tank 40
Fill with cold water below ℃.

After the above, the dried seed rice packed in the mesh bag 10 is stored in each storage basket 8 of the seed storage container 9, and the seed storage container 9 is hung by a self-propelled crane 53 to immerse in hot water soaking. It is transported to the tank 30 and heated in 57 ° C hot water for 1 hour.
Soak for 5 minutes.

After the above, the rice seed storage container 9 is pulled up from the hot water soaking tank 30 for sowing by the self-propelled crane 53, transported onto the cold water tank 40, and immersed in cold water of 20 ° C. or lower to be cooled.
