Description

The present invention relates to a wash-free rice maker for producing wash-free rice that can be cooked without polishing with water.

Wash-free rice is widely used in ordinary households because it saves time and effort for washing rice before cooking and also has a water-saving effect.

There are various methods for producing non-washed rice, such as washing and drying method (wet), dry method, BG manufacturing method, and NTWP manufacturing method. Of these, the washing and drying method is to wash the polished rice with water in a short time to remove skin shavings. ， It is a method to produce wash-free rice by drying in a short time.

As a conventional non-washed rice maker for producing wash-free rice by a water-washing drying method, for example, as shown in FIG. 6, a mixing tank 83 connected to a white rice tank 81 and a water supply pipe 82, and a transfer pipe 85 are connected to the mixing tank 83. A rice washing machine 87 connected via a stirrer and provided with a stirrer inside, a dehydrator (centrifugal dehydrator) 88 connected to the rice washing machine 87 via a transfer pipe 85 and dehydrated by a centrifugal separation action, and the dehydrator 88. A wash-free rice-making machine 80 including a dryer 90 connected via a rotary valve 89 and dried by warm air has been invented (Patent Document 1).

According to the above-mentioned non-washing rice making machine 80, both rice milling and water having a constant flow rate are transferred from the white rice tank 81 and the water supply pipe 82 to the rice washing machine 87 via the mixing tank 83, and the rice is washed by the rice washing machine 87 provided with the stirrer. The paste layer is removed by the action, the polished rice that has been washed by the dehydrator 88 is dehydrated, and the polished rice dehydrated by the dryer 90 is further dried with warm air to produce wash-free rice.

Further, the wash-free rice maker 1 may include a housing (not shown) that surrounds the entire apparatus.

Next, the operation of the wash-free rice making machine 1 of the present embodiment will be described.

The polished rice put into the rice supply pipe 15 is supplied into the rice washing chamber 17 of the rice washing unit 10 through the rice feeding port 14. At the same time, an appropriate amount of sharpening water is supplied to the rice washing chamber 17 from the water supply port (not shown) of the rice washing cylinder 12. The ratio of polished rice to sharpened water is preferably 1: 3.

In the rice washing unit 10, the rice washing roll 11 rotates at a predetermined speed (for example, 600 rpm) in synchronization with the rotation of the spindle 3 in the rice washing chamber 17, and the polished rice is generated by the ridges 11b of the rice washing roll 11. It is conveyed to the terminal opening 12b of the rice washing cylinder 12 while being stirred together with the polishing water, and while being pressurized by the resistance plate 40, the polished rice is rubbed against each other or between the polished rice and the cylinder (wire net) 16 in the polishing water. ， Washing (so-called sharpening) action of polished rice is performed.

The polished rice and the polishing water that have been washed are discharged from the communication hole 63a by pushing the resistance plate 40 open, and are supplied into the dehydration cylinder 22 of the dehydration section 20.

In the dehydration section 20, the stirring body 21 rotates at a predetermined speed (for example, 600 rpm) in synchronization with the rotation of the spindle 3, while the dehydration cylinder 22 does not synchronize with the spindle 3 and independently at a predetermined speed. It is rotating (for example, the spindle 3 rotates counterclockwise at 600 rpm, while the dehydration cylinder 22 rotates clockwise at 1000 rpm).

In the direction of rotation, when viewed from the right side of the paper in FIG. 1, the spindle 3 is counterclockwise by the motor 8, and therefore, the stirring screw 31, the cylindrical sleeve 31a, and the spiral blade installed on the outer peripheral surface of the cylindrical sleeve 31a. Similarly, the rice washing roll 11 of 31b is in the counterclockwise direction, and the dehydration cylinder 22 is in the clockwise direction by the motor 28.

Further, in the dehydration section 20, an appropriate amount of rinsing water and air are supplied into the dehydration cylinder 22 from the water supply holes 66 and 66.

The polished rice that has flowed into the dehydration cylinder 22 of the dehydration section 20 together with the sharpening water is rinsed by bathing in rinsing water while being stirred by the stirring body 21. Then, the rinsing water and the sharpening water are discharged from the net hole of the dehydration cylinder 22 by centrifugal force and dehydrated. At this time, while the polished rice is dried by the hot air from the duct 53 installed above the dehydration section 20, the centrifugally dehydrated sewage (sharpening juice and rinsing water) is discharged below the dehydration section. The dehydrated polished rice is conveyed to the rear end opening 22b of the dehydration cylinder 22 by the blade body 21b provided in the stirring body 21 with a slight amount of water adhering to the surface thereof, and the communication hole 63b of the second partition wall portion 62b. It is supplied into the drying cylinder 32 of the drying unit 30 via the above.

In the drying unit 30, the stirring screw 31 is rotating at a predetermined speed (for example, 600 rpm) in synchronization with the rotation of the spindle 3.

The polished rice supplied into the drying cylinder 32 of the drying unit 30 is transferred to the rear end opening 32b of the drying cylinder 32 while being agitated by the stirring screw 31, and the hot air flowing from the duct 53 of the dryer 50 (main). In the embodiment, the rice is exposed to a temperature of less than 50 degrees Celsius), and the water adhering to the surface is completely removed and dried to obtain unwashed rice.

In the drying unit 30, water, powder, rice rupture, etc. are discharged from the net hole of the drying cylinder 32 by the hot air flowing in from the duct.

Then, the polished rice that has not been washed is discharged from the discharge pipe 37 of the lid 35.

In this way, the polished rice after washing is completely dehydrated, so that there is no risk of mold formation and high-quality wash-free rice can be produced.

FIG. 5 shows another embodiment of the washing-free rice maker 1 of the present invention, in which the gantry 60 includes a front (paper, left) frame 68 and a rear frame 69, and the rear frame 69 can move up and down. The gantry 60 can be tilted.

As shown in FIG. 5, the wash-free rice making machine 1 of the present embodiment is tilted downward (about 20 °) toward the drying portion 30 so that the rice washing portion 10 side (on the paper surface, left side) is higher. is set up.

By installing the non-washed rice maker 1 at an angle as shown in FIG. 5, the rice supplied from the rice supply port 14 is discharged from the discharge port 36 through the above-mentioned rice washing, dehydration and drying steps. Since the weight of the rice acts (naturally drops) before it is processed, it becomes difficult for the perishable rice to remain inside the wash-free rice manufacturing machine 1.

Further, in the washing-free rice maker 1 of the present embodiment, as shown in FIG. 5, the hoppers 72 and 73 for collecting the wastewater discharged from the dehydration section 20 and the drying section 30 are located below the dehydration section 20 and the drying section 30. It is installed in.
