Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a stirring rice mill with a rice bran mainly used at home.
[0002]
[Prior art]
A stirring rice milling machine described in JP-A-11-197521 is a rice milling hopper (rice milling basket) which is installed inside a rice bowl receiving container and has a large number of small holes, and rotates horizontally at the bottom. The rice bran is provided with a blade member for stirring rice, and the brown rice put into the rice hopper is stirred by the rotation of the blade member, and is mainly polished by friction with the inner wall of the rice hopper.
[0003]
In the stirring-type rice mill described in the above-mentioned publication, for example, 1 to 4 go brown rice can be polished at a time, and in this case, two proposals have been made regarding the control method of the rotational speed of the blade member and the milling time. ing. One of them is that a phase control circuit is provided to keep the rotational speed of the blade member substantially constant regardless of the amount of polished rice, and the time for polishing is increased or decreased in accordance with the amount of polished rice. The rotational speed is not particularly controlled (the larger the amount of milled rice, the greater the resistance of the milled rice, and the rotational speed of the blade member automatically decreases). Instead, the longer time is set for the milled rice. .
Japanese Patent Application Laid-Open No. 11-300221 also discloses that, for a similar agitating type rice mill, the number of rotations of the blade member is kept almost constant regardless of the amount of milled rice, and the milling time increases or decreases according to the amount of milled rice. Has been.
[0004]
[Problems to be solved by the invention]
In the stirring type rice mill, when the number of milled rice is not controlled, the number of milled rice increases and the number of milled rice jumps in the milled rice hopper and increases the amount of broken rice. There is a problem that the quality of the milled rice deteriorates. On the other hand, when the amount of polished rice increases, the rotational speed of the blade member decreases, stirring becomes weak, and the time for polishing is increased.
In addition, even in the case of a control system that keeps the rotation speed of the blade member substantially constant, for example, when a small amount (for example, 1 go) of brown rice is put into a polished rice hopper having a 4 go rice polishing capacity, the polished rice hopper is compared with the polished rice amount. The problem that brown rice that is too large and stirred by the blade member jumps inside to increase the amount of crushed rice and deteriorates the quality of the polished rice occurs. Moreover, in order to keep the rotation speed of the blade member constant regardless of the amount of polished rice, it is necessary to incorporate a complicated and expensive control device for controlling the power supply and the polishing time.
[0005]
Furthermore, the conventional agitating-type rice milling machine has a limit in one-time rice milling capacity (for example, a maximum of 4 go), so when exceeding that, once the rice milling is within the range of the rice milling capacity, It is necessary to remove the rice mill from the receiving container, move the rice mill inside to another container, set the rice milling hopper in the paddy receiving container again, put the additional brown rice into the rice milling hopper again, and switch on the rice milling machine. It becomes work. In addition, since the rice milling capacity depends on the size of the rice hopper, the rice hopper is enlarged, and the motor is also enlarged corresponding to the rice milling capacity. As a result, the rice milling machine must be enlarged. is there.
[0006]
The present invention was made in order to solve the above-mentioned problems of the conventional agitating-type rice milling machine, and can always achieve excellent rice quality regardless of the amount of milled rice, does not require a complicated and expensive control device, and reduces the size of the device. The purpose of the present invention is to obtain a stirring-type rice milling machine capable of producing a small amount to a large amount of milled rice without any limitation in the rice milling ability.
[0007]
[Means for Solving the Problems]
The present invention includes a rice bran provided with a measuring instrument at the bottom, a rice removal hopper installed below and formed with a plurality of small holes, a rice hopper having an openable and closable rice discharge opening, and a horizontal direction at the bottom. It is equipped with a blade member that rotates and stirs the rice, weighs the rice stored in the rice bran, puts it into a rice mill hopper, rotates the blade member to mill the rice, and then opens the rice mill discharge opening and after the rice milling A rice mill-stirred rice milling machine that automatically performs a series of operations of dispensing rice is pre-set with a single rice milling amount, an integral multiple of which can be arbitrarily set as the required rice milling amount. When the amount of polished rice is more than twice the amount of polished rice, a control device is provided that automatically and repeatedly performs the series of operations until the required amount of polished rice is reached.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
As mentioned earlier, if the size of the milled rice hopper is determined, there is an appropriate amount of milled rice, so the above-mentioned stirring rice milling machine always performs the milled rice with a certain milled rice amount (hereinafter referred to as the unit rice milling amount). The required amount of polished rice was obtained by repeating the above. Thereby, size reduction of a rice hopper, a motor, etc. can also be achieved.
Hereinafter, with reference to FIGS. 1-6, the stirring-type rice mill with a rice bran concerning this invention is demonstrated more concretely.
[0009]
As shown in FIG. 1 and FIG. 2, this stirring type rice mill with rice bran is a rice bran part 2, a rice milling part 3, a rice bran suction part 4, a rice milling container 5, and an operation part 6. Etc.
The rice bran portion 2 is composed of a brown rice tank 7 whose bottom plate is inclined, a measuring instrument 8 and a measuring motor 9 installed on the bottom portion thereof, and drives the measuring motor 9 to rotate the measuring trough by a predetermined angle (for example, one rotation). The brown rice tank 7 is configured to cut out the brown rice of a preset unit rice quantity from the brown rice tank 7 and discharge it to the lower rice milling section 3. In addition, such a measuring device itself is publicly known.
[0010]
As shown in FIGS. 3 and 4 in particular, the rice milling unit 3 includes a rice bran container 11, a rice milling hopper 12 installed on the inside thereof, a blade member 13 installed on the bottom thereof, a main motor 14 for rotationally driving it, It consists of a solenoid valve 16 or the like that opens and closes a milled rice discharge opening 15 formed on the side wall of the hopper 12.
Almost the entire side wall and bottom wall of the polished rice hopper 12 is used as a removal part in which a large number of small holes a are formed, and the rice cake peeled from the brown rice falls through the small holes into the rice bran container 11. The milled rice discharge opening 15 of the milled rice hopper 12 is normally closed by a valve body 16 a of the electromagnetic valve 16. An opening 17 serving as a milling rice discharge passage is formed at a location corresponding to the rice milling discharge opening 15 of the koji container 11, and an opening 18 serving as a koji discharging passage is formed at another location. The blade member 13 includes a disk-shaped seat 21 and a protrusion 22 formed on the upper surface thereof. The outer diameter of the seat 21 is set slightly smaller than the inner diameter of the milled rice hopper 12 (there is a minute gap that does not allow rice to be bitten), and the upper surface thereof is set to the same height or slightly higher than the milled rice discharge opening 15. The ridges 22 are formed radially from the center of the disc-shaped seat 21 to the outer periphery, and the rotation front side 22a is inclined downward. In this example, since the rice is always on the blade member 13, it can be said that the blade member 13 substantially constitutes the bottom surface of the milled rice hopper 12.
[0011]
The soot suction unit 4 includes a suction chamber 23, a soot bag (such as a vacuum cleaner bag) 19 installed therein, a fan 20 that evacuates the suction chamber 23, a fan motor 24 that drives the fan 20, and the opening 18 and a suction passage 25 that communicates the suction chamber 23 with the suction chamber 23.

[0012]
The operation unit 6 includes a power switch 26, a rice milling degree setting switch 27 (setting for white rice, split rice milling, etc.), and a rice milling degree adjusting switch 28 (for example, there is a slight difference in the amount of milling between new rice and old rice. Adjustment), a rice milling amount setting switch 29, a timer 30 (time reservation), a rice milling switch 31 (starting rice milling), and a display unit 32 are installed. According to the settings by these switches, the control device 33 is connected to the metering motor 9, The motor 14, the fan motor 25, and the electromagnetic valve 16 are controlled, and control information is displayed on the display unit 32 (see the block diagram of FIG. 5 for numbers).
[0013]
Next, with reference to a block diagram of the control circuit (FIG. 5) and a control flowchart (FIG. 6), the operation of the stirring rice mill with rice bran will be sequentially described.
S1: The power switch 26 is turned on.
S2: The milling degree is set by the milling degree setting switch 27. There is a certain relationship between the degree of milling and the milling time, and the milling time that matches the degree of milling is set based on this relationship.
S3 to S4: The degree of milling is finely adjusted by the degree of milling adjustment switch 28 as necessary.
S5: The necessary rice milling amount is set by the rice milling amount setting switch 29. This makes it possible to set a necessary rice milling amount that is an integral multiple of the unit rice milling amount (for example, a unit).
S6: Calculate the number of milled rice. The number of milled rices is (required rice milling amount / unit rice milling amount), that is, the above integer multiple.
S7 to S8: The rice milling end time is set by the timer 30 as necessary.
The above setting items are displayed on the display unit 32 by the control device 33.
[0014]
S9: The rice mill switch 31 is turned on. The control apparatus 33 controls each part as follows according to the said setting. When the timer is set, each part is controlled at the timing when all the rice milling work is completed at the set time.
S10: The weighing motor 9 is driven. The weigher 8 of the measuring device 8 rotates by a predetermined angle, cuts brown rice of a unit rice amount, and puts it into the rice hopper 12.
S11: The weighing motor 9 stops.
S12: The main motor 14 is driven and at the same time the fan motor 24 is driven. The blade member 13 is rotated at a constant speed by the drive of the main motor 14, the brown rice in the milled rice hopper 12 is stirred, and the brown rice is gradually polished mainly by mutual frictional force. The rotational speed of the blade member 13 is set in advance to a predetermined value so that the most excellent rice quality can be obtained on the premise that the amount of polished rice is polished in the rice hopper 12. On the other hand, the rice cake peeled from the brown rice falls into the rice cake container 11 through the small hole a of the milled rice hopper 12 and is sucked into the rice cake bag 19 in the suction chamber 23 through the opening 18 and the suction passage 25.
[0015]
S13: After a predetermined time, the main motor 14 stops.
S14: The electromagnetic valve 16 is operated, the valve body 16a is retracted, and the rice discharge opening 15 is opened.
S15: The main motor 14 is driven again. Rice in the milled rice hopper 12 escapes from the milled rice discharge opening 15 by the centrifugal force applied to the blade member 13, and is discharged to the lower rice mill container 5 through the discharge passage 10.
S16: The electromagnetic valve 16 is restored, and the valve body 16a closes the milled rice discharge opening 15.
S17: The main motor 14 stops.
S18: If the number of polished rice has not reached the calculated value of S6, the control of S10 to S17 is repeated.
S19: When the number of polished rice reaches the calculated value of S6, the milling operation is finished. At this time, the fan motor 24 also stops.
[0016]
【The invention's effect】
In the present invention, in a stirring rice mill with a rice bran, the amount of polished rice at a time is set to a predetermined amount (unit polished rice amount), and when the required polished rice amount exceeds the unit polished rice amount, it is measured until the required polished rice amount is reached. , Rice milling and paying out are repeated. Therefore, it is only necessary to determine one optimal rice milling condition (for example, the number of rotations) for the unit rice milling amount in advance, and even if the necessary rice milling amount changes, the rice milling can always be performed under the same rice milling conditions. As a result, the control device is simplified, reliability is improved, and cost is reduced.
In addition, since a hopper with the optimum size can be installed for the amount of polished rice, excellent quality of polished rice can be obtained at any time while the generation of broken rice is suppressed. In addition, many other parts such as motors are also suitable for the amount of polished rice. Since the size is improved, the milled rice portion can be reduced in size, and even if the rice bran portion is combined, the entire size can be compactly accommodated.
Furthermore, there is no limit to the rice milling ability, and a small to large amount of milled rice can be arbitrarily obtained. No complicated operation is required at that time.
