Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice washing device, and more particularly to a rice washing device effective for automatically washing a large amount of rice or similar grains for cooking rice or the like.

[0002]

2. Description of the Related Art Recently, with the development of the food service industry, large quantities of rice are being industrially cooked. For this reason, large amounts of rice are washed automatically.

There is a conventional rice washing apparatus of this type in which rice is continuously fed by using a screw to supply rice washing water while conveying rice. In addition, since the passage for washing rice is installed horizontally, it does not cause a change in height.Therefore, it is necessary to use a separate passage for conveying the rice after washing in the next step where the height changes. A transport means is provided.

[0004]

However, in the above-described conventional rice washing apparatus, the rice is merely conveyed by the screw in the conveying passage, and the contact efficiency with the conveying passage, the rice grains, or the cleaning liquid is poor, and sufficient washing is performed. For this purpose, a long washing route and a long time are required, and 4 to 5 tons of washing liquid is required for 1 ton of rice, so that both the equipment and the running cost are high.

Further, if the rice is forcibly given a complicated movement to make a vigorous contact with the other rice or forcibly brought into contact with the other rice, a lot of fine rice is produced and rice is cooked. Then, this becomes a paste, which significantly impairs the quality of rice.

Further, as described above, the rice washing device itself tends to be large, and a separate device is required for sending the rice after washing the rice to the next step, so that the whole device becomes larger and more complicated. It is also more expensive and has the disadvantage of having a high space occupation rate.

[0007] Therefore, the present invention has an object to solve the above-mentioned problems, is small in size and can sufficiently wash rice with a small amount of washing liquid, and further, sends rice after washing rice to the next step without a special device. The main purpose of the present invention is to provide a rice washing device that can be used.

[0008]

Means for Solving the Problems In order to achieve the above-mentioned object, the rice washing apparatus of the present invention, in a rice sending pipe for carrying rice to a required position by multiplying the flow of a rice washing liquid sent by a pump, The present invention is characterized in that a rice washing guide member in which a ribbon-shaped plate material is twisted is provided.

The rice sending pipe is connected to the discharge side of the pump,
It is preferable to connect a rice introduction pipe passing through the inside of the rice washing liquid tank to the suction side of the pump, and to provide a liquid suction port in the portion of the rice introduction pipe immersed in the rice washing liquid, It is preferable to equip the rice introduction pipe with a quantitative supply means for supplying a fixed amount of rice.

The fixed quantity supply means is provided with a measuring chamber provided in the middle of a supply path for supplying rice to the rice introducing pipe, and a measuring blade for dividing the measuring chamber into a unit chamber having a predetermined capacity.
By this rotation of the weighing blade, each unit chamber individually receives the rice that is supplied facing the receiving port from the upstream side of the weighing chamber, and each unit chamber individually receives the feeding port to the downstream side of the weighing chamber. Rice which is opposed to each other and is fed to the downstream side from the feed port, and it is preferable that a gap slightly larger than the grain size of rice grains is provided between the weighing blade and the weighing chamber.

It is preferable that the rice introducing port of the rice introducing pipe is provided with an adjusting means for adjusting the cross-sectional area of the introducing passage for introducing the supplied rice.

[0012] A vertically moving component that tilts downward toward the front end and has different strokes in the front and rear and a longitudinal component that accompanies this vertical movement cause the rice that has been washed from the rice-sending pipe to be sent while being sieved. It may be provided with a liquid shooter and a finish cleaning liquid supply means for supplying the finish cleaning liquid to the rice sieved by the shooter and sent out.

It is provided with a returning means for returning the cleaning liquid recovered after the finish cleaning with the shooter to the rice washing liquid tank, and an excluding means for overflowing and removing the cleaning liquid above a predetermined liquid level in the rice washing liquid tank. You can also

The rice introduction pipe is connected to the suction port of the pump at the horizontal pipe portion, and the washing liquid and rice flowing in the lower half portion of the horizontal pipe are placed in the horizontal pipe just before the suction port of the pump. It is preferable to provide a reversing guide in which a ribbon-shaped plate material is twisted by 180 degrees between the front and rear ends, and the ribbon-shaped plate material is reversed by applying a twist so as to flow in the upper half of the lateral pipe.

[0015]

With the above-described structure of the rice washing apparatus of the present invention, rice can be transported by feeding the flow of the rice washing liquid fed by the pump in the rice feeding pipe. Since the twisted rice washing guide member twists and accelerates the flow of the rice washing liquid and rice flowing through the inside of the rice sending pipe, the centrifugal force is applied to the rice. You can efficiently wash rice by rubbing it in a natural flow state with the washing liquid intervening on the inner surface of the rice-sending pipe, and there is no mechanical unreasonable force on such a rubbing state. It is possible to prevent inconveniences such as rice becoming fine rice, and moreover, these rice sending and washing can be accomplished at the same time with a free and simple piping route of the rice sending pipe,
It can be realized inexpensively with a simple and compact structure without taking a special place by using the existing route for transporting rice to the necessary process.

Further, a rice sending pipe is connected to the discharge side of the pump, a rice introducing pipe passing through the inside of the rice washing liquid tank is connected to the suction side of the pump, and the portion of the rice introducing pipe immersed in the rice washing liquid absorbs liquid. In the configuration having the mouth, the rice washing liquid in the rice washing liquid tank is sucked into the rice introducing pipe through the liquid suction port of the rice introducing pipe, and at the same time, the rice supplied to the rice introducing pipe is multiplied by the flow of the sucking rice washing liquid. Then, the rice washing liquid and the rice can be smoothly introduced into the rice feeding pipe to be used for the washing.

In the structure provided with the fixed quantity supply device for supplying rice to the rice introducing pipe in a fixed amount, the rice introducing pipe always supplies a stable amount of rice corresponding to the flow rate of the washing liquid sucked by the pump. Therefore, it is possible to stably achieve washing without excess or deficiency while feeding rice with the flow of the washing liquid to send rice.

From the upstream side of the measuring chamber, the constant amount supply means rotates the measuring blade that divides the measuring chamber provided in the supply path for supplying rice to the rice introducing pipe into unit chambers of a predetermined capacity. Each unit chamber receives rice individually supplied to the receiving port of each unit, and each unit chamber individually faces the sending port to the downstream side of the weighing chamber to send out the rice that it receives. With the structure that feeds rice from the mouth, the amount of rice fed per unit time to the rice introduction pipe can be adjusted by feeding the rice fed continuously in units of the amount depending on the rotation speed and rotation cycle of the measuring blade. It can be set, and in particular, at this time, since a gap slightly larger than the grain size of rice grains is provided between the measuring blade and the measuring chamber, rice can be prevented between the inner surface of the measuring chamber and the tip of the measuring blade. Preventing bite into rice It can be.

In a construction in which the rice introduction port of the rice introduction pipe is provided with an adjusting means for adjusting the cross-sectional area of the introduction passage for introducing the rice to be supplied, the rice is adjusted by adjusting the cross-sectional area of the passage. Rice in each unit room at the inlet is intermittently
Alternatively, even if supplied in a pulsating manner, in order to introduce this into the downstream side, the flow rate is restricted according to the adjusted passage cross-sectional area,
It is possible to continuously feed while maintaining an almost constant flow rate,
It is possible to achieve more stable and continuous rice transfer and washing.

A vertically moving component that tilts downward toward the front end and has different strokes in the front and rear and a forward and backward moving component that accompanies this vertical movement cause the rice after washing to be sent out through a rice sending pipe while sifting it out. In a configuration provided with a liquid shooter and a finish cleaning liquid supply means for supplying a finish cleaning liquid to the rice that is shaken by the shooter and sent out, the rice after washing rice is received by the shooter and sent out by a sieving operation and the next step While feeding it to the rice that has been subjected to this sieving operation, the finishing washing liquid is supplied from the finishing washing liquid supply means, and the washing liquid soiled by washing rice is efficiently finished and washed by the synergistic action of sieving and rinsing. At the same time, draining can be performed to prevent the washing liquid and the finishing washing liquid from affecting the next step.

By returning the cleaning liquid collected after the final cleaning with the shooter to the rice washing liquid tank by the returning means,
The cleaning liquid after finishing cleaning that is not very dirty can be reused as the rice cleaning liquid in the rice transfer pipe, and by removing the rice cleaning liquid above the predetermined liquid level in the rice cleaning liquid tank by overflowing it and removing it. With a simple device, it is possible to achieve sufficient rice washing while maintaining the predetermined cleanliness while updating the rice washing liquid with the washing liquid after the final washing.

The rice introduction pipe is connected to the suction port of the pump at the horizontal pipe portion, and the washing liquid and rice flowing in the lower half portion of the horizontal pipe are placed in the horizontal pipe just before the suction port of the pump. In the configuration provided with a reversing guide in which the ribbon-shaped plate material is twisted 180 degrees between the front and rear ends to invert by twisting so as to flow in the upper half of the horizontal pipe, the suction port of the pump is pumped from this horizontal pipe portion. The rice in the washing water flowing into the tank flows under the sideways pipe under its own weight due to its own weight and flows unevenly toward the lower part of the suction port of the pump, which touches the labyrinth fitting part with the impeller on the inner circumference of the suction port of the pump. The problem of biting into rice is that the flow of washing liquid and rice in the horizontal pipe is twisted along the 180-degree twisted shape of the inversion guide before the suction port of the pump. The washing liquid and rice flowing in the lower half of the horizontal pipe are inverted 180 degrees so that they flow in the upper half of the horizontal pipe, then come off the inversion guide and reach the center of the pump suction port while falling slightly due to their own weight. However, it is possible to prevent rice from being bitten into fine rice by being sucked without touching the labyrinth fitting portion with the impeller on the inner circumference of the suction port.

EXAMPLES The rice washing apparatus of the present invention will be specifically described below with reference to examples.

1 and 2 show the overall construction of a rice washing apparatus as an embodiment of the present invention. To explain this, a rice washing guide member 5 in which a ribbon-shaped plate material is twisted is provided in a rice feeding pipe 4 that conveys rice 3 to a required position by multiplying the flow of a rice washing liquid 2 sent by a pump 1. It is provided and the rice sending and the rice washing are achieved with such a simple structure.

Specifically, the pump 1 has a rice introduction pipe 7 connected to the suction port 6 side to suck the rice washing liquid 2 and the flow of the rice washing liquid 2 to suck rice 3 supplied at the same time. To feed the rice washing liquid 2 and rice 3 into the rice sending pipe 4 connected to the discharge port 8 side, and the flow of the rice washing liquid 2 is sent to a predetermined position in the rice sending pipe 4 by the pump 1. The rice 3 can be conveyed to a required position for the next process by multiplying the flow of the washing liquid 2 fed by the pump 1 through the rice feeding pipe 4.

At the time of this transportation, the twisted rice washing guide member 5 provided in the rice sending pipe 4 receives the rice washing liquid 2 and rice 3 which have been sent and passed through the rice sending pipe 4. Since the flow is accelerated by twisting it as shown in FIG. 3 while swirling, a moving force in the centrifugal direction is given to the rice 3 in particular, and the rice washing liquid 2 is placed on the inner surface of the rice sending pipe 4. The inner surface can be washed efficiently without the inconvenience of rice milling due to the natural friction with the inner surface.
According to the experiments conducted by the present inventor, a satisfactory result was obtained with 1 t of water for washing rice while sending 1 t of rice.

In order to absorb the liquid through the rice introducing pipe 7, in this embodiment, the rice introducing pipe 7 passes through the inside of the rice washing liquid tank 9 to the rice washing liquid 2 in the rice washing liquid tank 9 of the rice introducing pipe 7. The liquid suction port 11 is provided in the portion to be dipped. Therefore, the pump 1 uses the rice introduction pipe 7 and the washing liquid 2 for the rice.
At the same time as sucking the rice washing liquid 2 in the rice washing liquid tank 9 through the liquid suction port 1 of the portion to be dipped in, the rice washing liquid 2 for sucking the rice 3 supplied to the rice introducing pipe 7 is multiplied by these rice washing liquids. The liquid 2 and the rice 3 can be sent out to the rice sending pipe 4 to smoothly achieve the aforementioned washing of rice.

The receiving port 7a is adapted to receive the supplied rice 3 and drop it into the rice introducing pipe 7 so that the rice 3 can be multiplied by the rice washing liquid 2 sucked by the pump 1 by its own weight. Along with this, the liquid suction port 11 is formed as a large number of holes evenly distributed on the peripheral wall of the portion of the rice introducing pipe 7 which is immersed in the rice washing liquid 2. As a result, the rice washing liquid 2 flows evenly into the rice introducing pipe 7 through the liquid suction port 11, and the rice 3 which has been supplied and dropped is wrapped in the flow so that it can be multiplied without leaving any excess. Thus, the pump 1 can be smoothly sucked and discharged.

Above the receiving port 7a of the rice introducing pipe 7, as shown in FIGS. 1, 4 and 6, there is provided a constant quantity supply means 21 for supplying a constant quantity of rice 3.

As a result, the rice 3 is always stably supplied to the rice introducing pipe 7 in proportion to the flow rate of the rice washing liquid 2 absorbed by the pump 1.

Prevents rice from biting into thin rice It can be.

In the rice introducing port, the rice introducing port is provided with the adjusting means for adjusting the cross-sectional area of the introducing passage for introducing the supplied rice, by adjusting the cross-sectional area of the passage by the adjusting means. Even if the rice in each unit chamber is supplied intermittently or pulsatingly to the rice inlet, the flow rate is limited according to the adjusted passage cross-sectional area in order to introduce this to the downstream side, It is possible to continuously feed while maintaining a constant flow rate, and it is possible to achieve more stable and continuous rice feeding and washing.

A vertical movement component that tilts downward toward the front end and has different strokes in the front and back and a forward and backward movement component associated with this vertical movement are used to screen the washed rice that is fed from the rice feeding pipe while sending it out. What has a configuration including a liquid shooter and a finish cleaning liquid supply unit that supplies the finish cleaning liquid to the rice that is shaken and sent out by this shooter, receives rice after washing rice with the shooter and performs sieving operation. Sending out While feeding to the next process, the finishing washing liquid is supplied from the finishing washing liquid supply means to the rice that has undergone this sieving operation, and the washing liquid soiled by washing rice is efficiently synergized by sieving and rinsing. It is possible to prevent the washing liquid and the finishing washing liquid from affecting the next step by performing the finishing washing and draining.

By returning the cleaning liquid collected after the final cleaning with the shooter to the rice washing liquid tank by the returning means,
The cleaning liquid after finishing cleaning that is not very dirty can be reused as the rice cleaning liquid in the rice transfer pipe, and by removing the rice cleaning liquid above the predetermined liquid level in the rice cleaning liquid tank by overflowing it and removing it. With a simple device, it is possible to achieve sufficient rice washing while maintaining the predetermined cleanliness while updating the rice washing liquid with the washing liquid after the final washing.

The rice introduction pipe is connected to the suction port of the pump at the horizontal pipe portion, and the washing liquid and rice flowing in the lower half portion of the horizontal pipe are placed at a position in the horizontal pipe just before the suction port of the pump. A pump having a structure provided with a reversing guide in which a ribbon-shaped plate material is twisted 180 degrees between the front and rear ends so as to invert by twisting so as to flow in the upper half of the lateral pipe The rice in the washing liquid flowing into the suction port of the pump flows under the side of the horizontal pipe due to its own weight and flows unevenly toward the lower part of the suction port of the pump, which touches the labyrinth fitting part on the inner circumference of the suction port of the pump with the impeller. , There is a problem of biting into fine rice, because the washing liquid and the flow of rice in the horizontal pipe,
Before the suction port of the pump, it is twisted along the 180 degree twisted shape of the inversion guide, so that the washing liquid and rice flowing in the lower half of the horizontal pipe can flow in the upper half of the horizontal pipe. After being inverted by 180 degrees, it comes off the inversion guide and falls slightly by its own weight to reach the central part of the pump suction port, and is sucked without touching the labyrinth fitting part with the impeller on the inner circumference of the suction port. It is possible to prevent the kind from being bitten into fine rice.
