Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grain humidifying device capable of more uniformly humidifying grains such as brown rice and white rice.

Humidification has conventionally been performed to bring overdried grains lacking moisture to a standard moisture content, but it has been difficult to perform this humidification efficiently and uniformly.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and provide a grain humidifying device that humidifies grains uniformly and efficiently. In order to achieve this object, the grain humidifying device of the present invention has a large number of vein umbrellas each having a cross section or a chevron shape mounted in parallel on the side wall of the grain tank, and one end of the vein umbrella is attached to the side wall. and the other end is closed, and an air duct and an air exhaust duct connected to the humidifier are connected to the air hole, and the air duct is located between the air duct and the air exhaust duct. a switching valve that communicates with the ventilation hole, and the exhaust passage communicates with the remaining ventilation hole; and the exhaust passage communicates with the certain ventilation hole, and the exhaust passage communicates with the remaining ventilation hole. It is characterized by having been established.

To explain the present invention with reference to an embodiment, a large number of chevron-shaped vein umbrellas 1 and 2 are hung horizontally or inclined in parallel on both side walls 4 and 5 of a grain tank 3. A through hole 6 is provided, and a chamber 7 facing the through hole 6 is provided outside the through hole 6. A chamber 11 is provided outside the through hole 9 provided in the other side wall 5, and the vein umbrella 2 is made to face the through hole 9. The vein umbrella 1 is connected to the hole 6. 10 is grain tank 3
15 is an upper grain feeding port.

Rooms 7 and 11 have air passages 1 equipped with electric heaters 17.
8 and 12 are connected, and the air passages 18 and 12 are connected to an ultrasonic humidifier 19 and a blower 20. The electric heater 17 may be replaced by a boiler heat exchanger. Reference numerals 13 and 14 indicate ventilation passages connected to the rooms 7 and 11, and between the ventilation passage 18 and the ventilation passage 13, and between the ventilation passage 12 and the ventilation passage 14, the ventilation passage 18 or the ventilation passage 13 is connected to the room 7. , and air duct 1
2 or a switching valve 1 that selectively communicates the exhaust passage 14 with the chamber 11;
These switching valves 15 and 16 are operated by solenoids 21 and 22, respectively, so that when the air passage 18 communicates with the chamber 7, the air exhaust passage 14 communicates with the chamber 11, and The exhaust passage 13 is operated alternately to communicate with the chamber 7 when the exhaust passage 13 communicates with the chamber 11.

23 is a cooling device provided for the blowers 18 and 12; 24 is a control valve that controls the flow of fluid into and out of the chambers 7 and 11;
5 is a grain supply port of the grain tank 3.

In the above configuration, the grains to be humidified are supplied from the grain supply port 25 of the grain tank 3, and the solenoids 21 and 22
The ultrasonic humidifier is operated by operating the switching valves 15 and 16 so that the chamber 6 communicates with the air passage 18 and is cut off from the air exhaust passage 13, and the chamber 11 is isolated from the air passage 12 and communicates with the exhaust air passage 14. 1
9 and the blower 20 are operated, the humid air containing moisture generated by the ultrasonic humidifier 19 is sent to the air passage 1 by the blower 20.
8 and sent into room 7. The moist air sent into the chamber 7 is introduced into the grain tank 3 through the ventilation hole 6, is discharged outside the vein cap 1, falls from the grain supply port 25, and is divided by the vein caps 1 and 2. It comes into contact with the grains that come in contact with the grains, imparts moisture, and is discharged to the outside through the veins 2, through the holes 9, and from the chamber 11 through the exhaust air passage 14.

At this time, the grains near the lower opening of the vein cap 1 are sufficiently hydrated by the moist air discharged from the lower opening of the vein cap 1, and fall through the part far from the vein cap 2. Furthermore, while the grains that pass through the part near the lower opening of the vein cap 1 below the vein cap 1 are given sufficient moisture, the grains passing through the part far from the bottom opening of the vein cap 1 are released from the lower opening of the vein cap 1. The grains that have already passed through the portion close to the lower opening come into contact with the fluid whose moisture content has decreased due to absorption of moisture by the grains, and the fluid passes through the portion close to the lower opening of the striated cap 2 and further from the lower opening of the striated cap 1. Since the grain passes through a far part, a difference in moisture is given between the grain passing through a part near the lower opening of the vein cap 1 and the grain passing through a part far from the lower opening of the vein cap 1, resulting in a difference in the moisture given to the entire grain. uniform humidification will not occur.

Therefore, the switching valves 15 and 16 are switched by the solenoids 21 and 22, so that the chamber 6 is cut off from the air intake path 18 and communicated with the air exhaust path 13, and the chamber 11 is opened for air intake. It communicates with the air passage 12 and is cut off from the air exhaust passage 14. Then, the humid air sent from the blower 20 flows through the air passage 12, the chamber 11, the striated umbrella 2, the striated umbrella 1, the chamber 6, and the exhaust passage 13 in this order, so that from the lower opening of the striated umbrella 1, The grain passing far away and close to the lower opening of the striated cap 2 is sufficiently hydrated by the moist air emanating from the lower opening of the striated cap 2.

If the grains need to be humidified, the electric heater 17 may be used to warm the moist air, and if the grains need to be cooled, the cooling device 23 may be used to cool the moist air.

As described above, the grain humidifying device of the present invention has a large number of vein umbrellas each having a chevron-shaped cross section mounted in parallel on the side wall of a grain tank.
One end of the striated umbrella is connected to a through hole provided in the side wall, and the other end is closed, and an air passage and an air exhaust passage connected to a humidifier are connected to the air hole, and the air air passage and exhaust air passage are connected to each other. Between the air passages, the air passage communicates with a certain ventilation hole and the air exhaust passage communicates with the remaining ventilation hole, and the air exhaust passage communicates with the certain ventilation hole and the air ventilation passage communicates with the remaining ventilation hole. Since the grain is characterized by a switching valve that communicates with the through hole, the moisture in the humid air is applied to the grains more uniformly, and the grains come into contact with the humid air while the flow is divided. Moisture application is performed efficiently.
