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 flowing into the tank, it is possible to automatically switch between supplying or stopping the humid air to the humid air supply path in the same row at that phase depending on the amount of grain in the tank. The structure is easy to operate, and it reliably prevents the stagnation of humidification effect due to blowing air, and the appropriate amount of humid air always straightens the rice grain layer smoothly to ensure efficient humidification effect quickly. The aim is to develop and provide high-performance equipment.

To explain the present invention with reference to embodiment diagrams, grain tank 1
At the lower part of the non-humidifying humidity control device 2 installed on the upper part of the grain tank 1, a large number of angle-shaped steel vein umbrellas 3, 4...... are hung horizontally in parallel between the both side walls 5, 6 of the grain tank 1. A large number of through holes 7 are provided in the side wall 5.
A ventilation chamber 8 facing the wall is provided and connected to the humidifier, and a ventilation hole 9 provided in the other side wall 6 is provided with a veined umbrella 4 forming an air exhaust path.
It faces and communicates with the ventilation chamber 23, and a striated umbrella 3 forming an air supply path is connected to the ventilation hole 7, and a section where the striated umbrellas 3 and 4 are hung horizontally forms a humidifying chamber 10. A non-humidifying tempering device 11 is provided at the bottom of the humidifying chamber 10 of the grain tank 1, and discharge valves 13, 14, 15 of rotary impellers are connected to the discharge ports 12, 12, 12 at the bottom of the humidifying chamber 10. 4, and the rice grains flowing down from the discharge ports 12, 12, 12 are passed through the screw conveyor 16 and sent to the grain lifting machine 1.
7, the grains are fried, discharged, and supplied to the grain feeding section 18 of the grain tank 1. A scatterer 19 is rotatably mounted on the upper non-humidifying tempering device 2 of the grain tank 1 in order to uniformly flow down the rice grains. An air passage 20 is connected to the outer wall of the air supply chamber 8 and connected to an ultrasonic humidifier 21 and a blower 22 of the humidifier. Each through hole 9 of the striated umbrella 3 forming the air supply path is arranged in the same row laterally.
A shaft body 25 equipped with an opening/closing plate 24A that rotates to open and close each through hole 7 is horizontally mounted on the outer wall surface of the side wall 5 provided with . The shaft is rotatably installed by a stopper 26..., and the side wall 5 of the shaft end 27 of the shaft body 25
An on-off valve opening/closing mechanism 28 such as an electromagnet fixedly attached to the on-off valve opening/closing mechanism 28 is connected via a connecting rod 29, and the shaft body 25 rotates due to the operation of the on-off valve opening/closing mechanism 28, thereby opening and closing each of the on-off valves 24.
It is shaped so that it can be opened and closed.

Further, the tops of the vein umbrellas 3 in the grain tank 1 are connected to each other by a horizontal rod 30, and
A rice grain detection device 33 such as a photoelectric device comprising a light source 31 and a light receiving element 32 is suspended from the horizontal rod 30, and an electric circuit 34 is installed so that the opening/closing valve opening/closing mechanism 28 is operated by a detection signal from the detection device 33. are connected via.

The on-off valve 24 of the second embodiment shown in FIG. 4 has an on-off valve opening/closing mechanism 2 such as an electromagnet fixed to the side wall by attaching a strip-shaped shutter plate 35 to each of the through holes 7.
8, and is configured to open and close each through hole 7 by vertical movement of the shaft 36.

With the above-described configuration, the raw rice grains hoisted by the hoisting machine 17 to the grain tank feeding section 18 are transferred to the scattering machine 19.
Due to the rotation of the rice grains, the rice grains are collected in a dispersed manner over the entire surface of the tank, and the rice grain layer formed in the tank is detected by the grain detection device 33 in the middle of the tank.
When the rice grains accumulate at the position, the light receiving element 32 receives the reflected light emitted from the light source 31 of the detection device 33 onto the rice grains.
receives the light, and communicates the detection signal to the electric circuit 34 to operate the on-off valve opening/closing mechanism 28. In FIG. Rotate each opening/closing valve 24.
…………open all at once. Next, 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 33 installed in the upper stage of the tank, the on-off valve 24 in the same column receives the detection signal from the detection device 33. Therefore, the air outlet of the air supply chamber 8 is closed while maintaining the same state. Then, when an arbitrary rice grain layer is formed in the grain tank 1 and the device is started,
The humid air generated by the ultrasonic humidifier 21 and sent to each air passage 20 by the blower 22 is sent to each air passage through each air passage 20 which is opened by the switching rotation. 7...... respectively, and the vein umbrella 3 of the air supply path
The air passes through the rice grain layer formed in the humidifying chamber 10, flows into the striated umbrellas 4 of the ventilation channels provided on both sides of the upper part, and flows from the ventilation holes 9 through the ventilation chamber. The rice grains in the rice grain layer formed during this time are humidified. Further, the humidified rice grains are discharged into the lower grain collecting tank by rotation of the discharge valves 13, 14, and 15, and the rice grains are returned to the grain tank 1 by the screw conveyor 16 and the grain lifting machine 17. Ru. This rice 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.

As described above, in the rice grain humidifying device of the present invention, the on-off valves of each of the through holes are mounted on the side wall in which the through holes of the veined canopy serving as the air supply path are provided so as to be openable and closable, and the on-off valves of the through holes are respectively mounted on the side wall in which the through holes of the veined canopy serving as the air supply path are provided. The structure forms a humid air supply chamber, and connects an on-off valve opening/closing mechanism that opens and closes each of the on-off valves and an electric circuit of a rice grain detection device located at approximately the same height as the through hole in which the on-off valves are located. Therefore, in the tank of the humidifier, the opening/closing valve of the through hole connected to the vein umbrella at the position where the rice grain layer is formed automatically opens and supplies air according to the detection signal of the rice grain detector. ,
The veins in the positions where the rice grain layer is not formed are closed due to the lack of signal, and the opening/closing valve of the air supply duct is closed.
In the rice grain layer formed by any grain amount,
It automatically and completely prevents humid air from blowing through the upper space in vain, and also prevents the humidifying effect from stagnation caused by the air blowing, and also provides a feed according to the amount of grain. In addition to making it easy to switch and adjust the on-off valve of the air passage hole, the appropriate amount of moist air rectifies the rice grain layer to ensure efficient humidification.
In addition, it can be carried out quickly and has the effect of constantly mass producing high quality humidified rice grains.
