Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a rice grain humidifying device, and an object of the present invention is to prevent the upper space of the rice grain layer formed by a given amount of grains from being unnecessarily blown through in the grain tank of the rice grain humidifying device. In order to completely prevent the humid air from flowing, it is possible to automatically switch between supplying or stopping the humid air to the humid air supply path in the same phase in accordance with the amount of grain in the tank. In addition, it has a simple structure and is easy to operate, and it reliably prevents the stagnation of humidification effect caused by blowing air, and the appropriate amount of humid air always straightens the rice grain layer smoothly, ensuring efficient humidification effect quickly. The aim is to develop and provide high-performance equipment to carry out the project.

To explain the present invention with reference to embodiment diagrams, grain tank 1
At the lower part of the non-humidification tempering device 2 installed in the upper part of the grain tank 1, a large number of angle steel vein umbrellas 3, 4 are hung horizontally in parallel on both side walls 5, 6 of the grain tank 1. A ventilation hole 7 is provided to communicate with an external air supply chamber 8, and a veined umbrella 3 forming an air supply path is exposed to the ventilation hole 7, and a ventilation hole 9 provided in the other side wall 6 is connected to the air supply chamber 8 outside. faces the veined umbrella 4 forming an air exhaust path, and communicates with the ventilation chamber 10 outside the side wall 6, and each of the veined umbrellas 3...
A humidifying chamber 11 is defined as an area where 4...... are horizontally placed. A non-humidifying tempering device 12 is provided at the bottom of the humidifying chamber 11 of the grain tank 1, and discharge ports 13, 1 are provided at the bottom of the humidifying conditioning device 12.
3, 13 are rotor wheel discharge valves 14, 15, 16
horizontally in parallel with the striated umbrellas 3 and 4, and the outlet 13,
The rice grains flowing down from 13, 13 pass through a screw conveyor 17 and are sent to the grain feeding section 1 of the grain tank 1 by a grain lifting machine 18.
A scattering machine 20 is rotatably mounted on the upper non-humidifying conditioning device 2 of the grain tank 1 to uniformly flow down the rice grains. The air supply chamber 8 communicates with each of the through holes 7 arranged in the same row in the horizontal direction, and also communicates with each of the air supply chambers 8A, 8 arranged in every other row.
B, 8C are air passages 22A, 22 equipped with on-off valves 21;
B, 22C, and each air passage 22
One end side of A, 22B, 22C is an ultrasonic humidifier 23
The air blowers 25 of the humidifier 24 are connected to the wind pipes of the air blowers 25, respectively. And each of the air passages 22A, 22
B, 22C respective on-off valves 21, 21, 21
The electromagnet 2 of the solenoid that becomes the opening/closing mechanism is installed in the
6 are connected to each other by a connecting rod 27 so as to be openable and closable, and the veined umbrellas 3 in the same row are connected to the air supply chambers 8A, 8B, and 8C, respectively. It is detected that rice grains have accumulated on the top of the upper end. Grain detection device 2 for
8 are provided, and the tops of the striated umbrellas 3, 3 of each stage are connected by a horizontal rod 29, and the detection device 28 is fixedly installed on the rod 29.

Further, the detection device uses an electric device such as a level meter or a photoelectric device, and the detection device is installed at the same height as the vein umbrella 3 of each stage, and the detection signal is communicated to the electric circuit 30. The through holes 7 of the vein umbrellas 3 in the same row are formed so as to open and close the valve 21 by operating the electromagnet 26.

With the above-described configuration, the raw rice grains fried by the grain lifting machine 18 to the grain tank feeding section 19 are transferred to the scattering machine 20.
As the rice grains rotate, they are dispersed over the entire surface of the tank and fall uniformly, and the rice grains accumulated in the tank form a layer of rice grains that almost buries the vein umbrella 3 that communicates with the lower air supply chamber 8C. When the grains are formed, the rice grain detection device 28 installed at the same height detects the grains and sends the signal to the electric circuit 30 to activate the electromagnet 26, which blocks the air passage 22C located in the same row. The on-off valve 21 is switched to open. Furthermore, when the rice grains are fried and supplied and the rice grain detection device 28 installed at the middle stage in the tank detects the rice grain layer formed at that position, the detection signal is used to open the air passage 22B communicating with the middle stage air supply chamber 8B. Open/close valve 2
1 is opened, and when the grain frying operation of the raw material is interrupted and the formation of the rice grain layer stops up to the rice grain detection device 28 installed in the upper stage of the tank, the opening/closing valve 21 in the same column is opened.
will remain in that state and block the air passage 22A.

When an arbitrary rice grain layer is formed in the grain tank 1 and the device is started, the moist air generated by the ultrasonic humidifier 23 and sent to each air path 22A, 22B, 22C by the blower 25 is The air flows into each of the through holes 7 through the air channels 22B and 22C opened by the air flow, passes through the rice grain layer formed in the humidifying chamber 11 from the striated umbrella 3 of the air supply channel, and passes through the rice grain layer formed in the humidifying chamber 11, and the air flows upward. The air flows into the veined umbrellas 4 of the air exhaust passages provided on both sides and is removed from the machine through the ventilation holes 9 through the air exhaust chamber, and the rice grains in the rice grain layer between them are humidified. be done.
In addition, the humidified rice grains are removed from the discharge valves 14, 15, 16.
The rice grains are discharged into the lower grain collecting tank by the rotation of the rice grains, and the rice grains are returned to the grain tank 1 by the screw conveyor 17 and the grain lifting machine 18. This grain circulation process is repeated several times to humidify the rice grains to a predetermined moisture content, and the rice grains are sequentially carried out of the machine and subjected to the next process.

In this way, the rice grain humidifying device of the present invention has a large number of veined umbrellas, which serve as air supply paths, arranged in parallel and mounted vertically every other row, and each of these through holes is provided on the outside of the side wall. , A plurality of air supply chambers are arranged to communicate with the parallel ventilation holes of each stage row, and each air supply chamber is connected to an air passage provided with an on-off valve to communicate with the humidifier. Because of this structure, in the tank of the humidifier, the air passage communicating with the striated umbrella at the position where the rice grain layer is formed automatically opens and supplies air in response to the detection signal of the rice grain detector. Since the air passages of the striated umbrellas at positions where no layer is formed are blocked due to no signal, the moisture wind that tries to wastefully blow through the space above the rice grain layer formed by a given grain amount. Automatically and completely prevent
This eliminates the phenomenon of stagnation of humidification effect induced by the above-mentioned open draft, and makes it easy to change and adjust the air passage according to the amount of grain. The present invention has the effect that a good humidification effect can be carried out reliably and quickly, and that high-quality humidified rice grains can always be mass-produced smoothly.
