Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device that can deliver rice grains extremely easily, and is particularly needed directly at a rice production site that consumes a large amount of rice grains, such as in the food service industry, without subdividing into a large amount of bags and when necessary. The present invention relates to a mobile rice grain delivery device and a rice grain delivery receiving device using the same, which can deliver a large amount of rice grains in a clean and prompt manner.

[0002]

2. Description of the Related Art A large amount of rice is consumed every day in the food service industry, the food industry, etc., and this rice is delivered and supplied daily by rice grain distributors. As a work form for this delivery, one kettle worth of polished rice for each customer, for example, 2 kg to 6 k
Various types of polished rice of various g are packed in small bags with various contents, and it is difficult to handle as small bags, so it is double-packed every few more pieces and loaded into a delivery vehicle to deliver the required amount each time. The form is generally used. The current situation is that the loading and unloading of rice bags usually depends on human work. At the customer's site, the delivered rice is rarely used immediately and is usually stored in a corner of the kitchen site or in a separate warehouse. And this storage is usually done directly on the ground.

[0003]

The current delivery mode and storage method as described above have various problems as described below. First of all, about 30 kg of rice bags must be loaded on the truck for delivery, and the other party must wholesale the bags, which results in an extremely heavy physical burden, and the workability is naturally low. For example, in a large-scale factory, the daily consumption of rice in the employee cafeteria is over 1 ton, and if we try to deliver it in rice bags containing 5-5-6 small sachets, we will have more than 35 bags of about 30 kg. However, just loading and unloading from a delivery vehicle would be a great effort. Especially for rice bags, which are the enemy of getting wet with water during transportation, delivery on a rainy day can be a terrible task.

Secondly, the delivered rice is rarely used immediately and is temporarily stored in one corner of the kitchen or in a separate warehouse, so that it may be exposed to water during the process, or even grow. When the bag is opened and rice is put into the rice cooker during rice cooking, dust and the like attached to the bag will be mixed in the rice cooker. In the case of normal white rice, this mixed dust may be removed to some extent because it is washed, but in the non-washed rice according to the invention of the present inventor, the rice washing step is not performed. It is impossible to remove it.
This non-washed rice has been debranched in advance by washing with water or other methods at the stage of rice polishing, and it is possible to omit the washing and dipping steps, and it has been noted that the number of steps in the rice cooking step can be greatly reduced. . However, originally, it should be advantageous that the rice washing process is not performed, but since the dust mixed in at the time of opening cannot be removed, it may be a disadvantage on the contrary. That is, the great advantage of non-washed rice cannot be fully exerted due to the problem that dust adheres to the rice bag. And, it is clear that the cause of this dust contamination is due to the method of delivery and storage, but it is almost impossible to realize a delivery vehicle or storage place without dust.

Thirdly, the work and management of bag packing become difficult for rice grain manufacturers. This is because the amount of rice put in the kettle differs for each customer, so it is necessary to pack one sachet for each customer. This is extremely inefficient in working and, in addition, since it is almost manual to double-pack every few pieces, it is a more difficult work.

Fourthly, since rice for the food service industry is collected in large quantities, rice grain sellers sell it at a relatively low price, but due to the small bagging and double packing, the bag cost and bagging cost are high. See
The profitability is not right.

Fifth, in the food service industry as well, care must be taken in the storage area so that water will not be splashed during storage.
When cooking rice, it is necessary to go to the storage place each time, open a large bag and open a small bag each time, which is very troublesome, and a small amount of rice grains remain in the bag when opening, and it is useless. It will be that.

Sixth, empty bags after opening, which are generated in a voluminous quantity every day in the food service industry, become trash, and it is difficult to dispose of them.

[0009] Seventhly, in the food service industry, since the rice bags are taken out in order from the upper bag which is inevitably stacked, the rice bags at the lower end are not replaced and are not used for a long period of time because the rice bags at the bottom are not replaced. There is a problem that the quality of is deteriorated.

[0010]

[Means for Solving the Problems] As described above, there are many problems in the conventional delivery method and receiving method using rice bags,
The present invention has been made as a solution to all of these problems. By the way, various problems have been considered in the industry to solve the above problems, but no practical means has been found to date. The factor that hinders the realization of the practical means is that there are too many requirements to be solved. Above all, the rice to be delivered is milled rice with the bran layer removed and it is stripped naked, so if you handle it a little rough, the rice skin will be rough and you will not be able to cook as satisfying rice, and it will be unusable Because. Therefore, for example, when rice is transferred by an air transporter for powder and granules using a transfer hose, which is used in the industrial world, broken rice or roughened rice grain surface occurs. In recent years, it is possible to reduce broken rice by improving the technology, but it has not been enough to prevent the roughening of the rice grain surface, and even the latest technology of air transportation causes roughening of the rice grain surface. This rough skin makes it impossible to cook satisfying rice, which is extremely unsatisfactory in the food service industry.
However, if the transfer speed is reduced, it is possible to prevent the surface of the rice grain from becoming rough, but this is not feasible because it remains in the transfer hose. Therefore, as disclosed by the present inventor in Japanese Examined Patent Publication No. 2-48443, the finding that if the collision speed when dropping rice grains is 4.4 meters per second or less, the impact can be sufficiently endured, the transfer hose is described. By applying to the transfer speed of rice grains in the inside, by setting the surface roughness of the inner surface of the transfer hose within the optimum range and further buffering the collision energy of rice grains, the rice grains can be damaged even at a speed of 6 meters per second or less. It was possible to realize the transfer without any need, and it was the completion of the present invention.

In order to solve the above-mentioned problems, the present invention provides a mobile rice grain delivery device and a rice grain delivery acceptance device using the same. First, as a mobile rice grain delivery device, a vehicle-mounted rice grain tank is provided. And an air transfer means for transferring the rice grains in the rice grain tank with a transfer hose having an inner surface having a center line average roughness of 100 μm or less at a nominal speed of 6 m / sec or less. Yes, a rice grain storage tank that also serves as an airtight chamber between the rice grain tank and the air conveying means, and a measuring means for detecting the amount of rice grains transferred, or between the rice grain tank and the air conveying means The configuration is such that a weighing means for weighing rice grains, a storage unit for storing the rice grains weighed by the weighing unit, and a valve body for discharging the rice grains in the storage unit are provided.

[0012] As a rice grain delivery receiving device using such a mobile rice grain delivery device, an on-vehicle rice grain tank,
The rice grain in the rice grain tank is transferred at a speed of 6 m / sec by a transfer hose whose inner surface has a center line average roughness of 100 μm or less.
It is equipped with a mobile rice grain delivery device equipped with an air transfer means for transferring at the following apparent speed, and a rice grain storage container provided indoors on the rice grain receiving side, and the mobile rice grain delivery device is brought close to the rice grain storage container, The tip of the transfer hose is directly or indirectly removably connected to the rice grain storage container, and at least rice grains within the void volume of the rice grain storage container are fed at a low speed. Then, one end of the rice grain receiving pipe is connected to the rice grain storage container, the tip of the transfer hose of the mobile rice grain delivery device is directly or indirectly connected to the other end of this rice grain receiving pipe, or the rice is sent from the mobile grain delivery device. At the position of the incoming collision point of the incoming rice grain, a plate-shaped collision cushioning member and a positional relationship that is tangential to the rice grain inflow direction, arc-shaped deceleration cushioning member, or a rice grain storage container or its A weight detecting means may be provided in the pre-process or the post-process, an output means of the detected weight data may be provided in the weight detecting means, and an input means of the detected weight data may be provided in the mobile rice grain delivery device,
Alternatively, the wall heating means is provided on the wall surface of at least one of the rice grain storage container and the rice grain receiving pipe.

[0013]

According to the above structure, the above problems can be solved by the following functions. First, in the mobile rice grain delivery device, according to the first aspect, since the rice grain in the tank is pushed out from the vehicle-mounted tank by the air conveying means, it is not necessary to bag the rice grain. When the surface roughness of the inner surface of the transfer hose is set to 100 μm or less in terms of center line average roughness and the transfer hose is transferred at an apparent speed of 6 meters or less per second, it is possible to prevent roughening of the rice grain when the rice particles collide with and rub against the inner surface of the transfer hose. In addition, air transportation contributes to simplification of the equipment. Further, the structure of claim 2 leads to high efficiency of the air transportation. And the structure of Claim 3 enables measurement of the amount of rice grains to be transferred.

On the other hand, in the rice grain receiving device, claim 4
According to 5, it is possible to store the dust-free state and transfer it to the storage container on the customer side with a small amount of labor regardless of the amount of delivery.

According to claims 6 to 10, prevention of crushed rice at the time of transfer and roughening of the surface of the rice grain, detection of void volume in the rice grain storage container, highly accurate control of rice grain transfer amount at the time of selling by weight, or rice grain storage container It is possible to prevent dew condensation on the rice grain receiving pipe.

[0016]

Next, the details of the present invention will be described based on specific examples. FIG. 1 schematically shows an embodiment of a mobile rice grain delivery device of the present invention as an overall structure.
In the illustrated example, an abacus ball-shaped on-vehicle rice grain tank 5 supported by a frame 2 on a bed of an automobile 1 as a moving means,
5 is mounted, and the rice grains in the tanks 5 and 5 are pushed out at a low speed.
Is airtightly connected to an air conveying means which is airtightly connected via a filter 4 and a transfer pipe 6. Hatches 7 and 7 are used for filling rice grains in the rice grain tanks 5 and 5, which are openable and closable and keep the tanks 5 and 5 airtight when closed. Reference numeral 8 is an air pipe connected to the upper parts of the tanks 5 and 5 from the compressor 3 in an airtight manner. A transfer hose 9 is airtightly attached to the tip of the transfer pipe 6, and is flexible and pressure resistant. The reference numeral 10 designates a mouthpiece, which is airtightly attachable to and detachable from a receiving port which will be described later. In addition, in order to prevent dust from entering the transfer hose 9 if necessary, a detachable or openable / closable lid is attached to the mouthpiece portion. Here, particularly important requirements for this mobile rice grain delivery device are that the inner surface of the transfer hose 9 has a relatively smooth surface with a center line average roughness of 100 μm or less, The speed of rice grains discharged with air is adjusted so that the assumed speed is 1.5 meters to 6 meters per second. This speed represents the most desirable speed range in an average transfer distance, and as a speed condition for achieving the object of the present invention, a speed of 6 meters or less per second may be set. The definition of this deemed speed is as follows.

In the transfer system of the present embodiment, when rice grains are transferred as a group of rice grains in the transfer hose 9 by air, they are naturally intermittent or pulsating. Therefore, it is almost impossible to accurately measure the speed at which rice grains are discharged from the mouthpiece 10.
However, since this discharge speed is one of the most important conditions in the present invention, the concept of "deemed speed" is introduced in the present application to make the conditions objective. That is, even if the assumed speed is different from the actual speed at any moment, the deemed speed is the transfer condition in the present invention.

The assumed speed is calculated by the following method. First, the compressor 3 is operated while the rice grain tanks 5 and 5 are empty, and the air is ventilated to measure the wind speed of the portion with the highest wind speed near the tip of the transfer hose 9 with an anemometer. Then, 40% of this wind speed is used as the speed at which the rice grains are fed when the rice grains are transferred. The transfer speed or discharge speed of rice grains in the present application is predicated on this assumed speed.

As described above, this speed condition is for preventing the surface of the rice grain from being roughened during the transfer. As the compressor 3, for example, a model 110V-7V5 / 6 manufactured by Hitachi, Ltd. is used, and the discharge pressure is 1. .3 kg /
cm ² , the total length of the transfer tube 6 and the transfer hose 9 is 13 m, and the inner diameters are 63 mm, the discharge rate of rice grains discharged from the mouthpiece 10 together with air is about 4 meters per second. The discharge deemed speed becomes faster as the displacement of the compressor 3 becomes larger, the air pressure becomes higher, and the inner diameter of the transfer hose 9 becomes smaller, and becomes slower in the opposite direction.

The discharge speed of this rice grain is optimally about 4 meters per second, and if it exceeds 6 meters per second, the surface of the rice grain will become rough even if a shock absorbing member or a speed reducing cushioning member, which will be described later, is provided. On the contrary, when the transfer speed is low, it takes a long time to transfer, and especially when the transfer speed is 1.5 m / sec or less, the transfer hose 9 is likely to be clogged with rice grains. Furthermore, even if the speed is 6 meters or less per second, unless the surface roughness on the inner surface of the transfer hose 9 is 100 μm or less in terms of the center line average roughness, the rice grain surface will be roughened. Therefore, by adjusting the size and pressure of the compressor 3 and setting the inner surface state and inner diameter of the transfer hose 9 to predetermined conditions, stable transfer of rice grains at an arbitrary speed within a predetermined range can be realized.

Next, another embodiment of the on-vehicle rice grain tank 5 is shown in FIG. The illustrated example has a hatch 7 that can be opened and closed at the top
At the lower end, a flow-down port 13 that can be opened and closed by a shutter 12 that can be moved up and down by a solenoid 11 is provided, and immediately below that, a rice grain storage tank 14 that faces the flow-down port 13 and also functions as an airtight chamber is provided. It represents. A butterfly valve 17 is provided on the upper portion of the rice grain storage tank 14 as a valve body that can be opened and closed airtightly, and the lower end is airtightly connected to the transfer pipe 6 via the free ducts 15 and 15. Further, the storage tank 14 is held by the frame body 2 via load cells 16, 16 as measuring means. Although not shown in the drawings, the frame body 2 is loaded on a loading platform such as a truck as in FIG. 1, and the transfer tubes 6 and 6 are hermetically connected to the compressor 3 and the transfer hose 9 on the vehicle, and the shutter is further provided. 12 and the butterfly valve 17 can be automatically opened and closed by a necessary signal. Reference numeral 18 is a cover for preventing rainwater and dust from entering. It should be noted that this drawing is a drawing for facilitating understanding, and the rice grain storage tank 14 is actually much smaller than the rice grain tank 5.

In addition to FIG. 2, another configuration example capable of metering and transferring a fixed amount of rice grains is also proposed in FIG. The example in the figure shows a rice grain tank 5 and a compressor 3
A weighing means 29 for weighing the rice grains in the rice grain tank 5, an accommodating portion 31 for accommodating the rice grains weighed by the weighing means 29, and an air conveying means such as the transfer pipe 6 and the casing 41 by the high pressure air. The valve body 33 for discharging rice grains in the storage unit 31 is provided, and the valve body 33 is used for discharging the rice grains to the transfer pipe 6. Weighing means 29
Is a hopper portion 37 for receiving rice grains in the rice grain tank 5,
The hopper unit 37 is provided with a weight detecting means 39 such as a load cell for detecting the amount of rice grains once stored as a weight, and a shutter function for paying out the rice grains to the storing unit 31 is provided although not particularly shown. . And the housing 31
The rice grains accommodated in (1) are airtightly discharged to the transfer pipe 6 by the valve body 33. The valve element 33 is desired to have a rotor 43 having a plurality of fins in a substantially cylindrical casing 41, and what is called a rotary valve is suitable. The compressor 3 here may be another pressure-feeding device capable of discharging high-pressure air.

The above-mentioned mobile rice grain delivery device described above is
The rice grain delivery and receiving apparatus is configured with the rice grain storage container for reception installed on the customer site side, and the configuration on the customer site side is described in detail in FIG. 4. In the example shown in the figure,
A rice grain storage container 5 equipped with a weight detecting means such as a load cell (not shown) on a rice cooking facility 51 installed in the building 50.
2 is installed. Therefore, the rice grain storage container 52 in this case is not a completely fixed installation in a strict sense. A rice grain receiving pipe 53 having an inner surface of a smooth surface and an inner diameter substantially the same as that of the transfer hose 9 is piped on the upper portion of the rice grain storage container 52, and a tip end of which is a connecting pipe protruding outside the building 50. The connection pipe 67 and the mouthpiece 10 at the tip of the transfer hose 9 can be connected airtightly and detachably. This figure shows the transfer hose 9
It shows that the are connected, the base 10
An appropriate lid that can be detached or opened and closed is attached so that dust does not enter the connecting pipe 67 when the connector is removed.
Reference numeral 54 denotes an outer panel attached to the outside of the building 50. The outer panel 54 is configured to be electrically connectable to the weight detection means of the rice grain storage container 52, and has a printer, a weight display function, and a mobile rice grain. If necessary, a connector for signal transmission to the delivery device may be provided.

Then, in the rice grain storage container 52, the rice grain feeding direction shown in the sectional view of FIG. The arc-shaped deceleration cushioning member 63 is provided in a tangential positional relationship, and the discharged rice grains are decelerated by being guided along the deceleration cushioning member 63 to provide a cushioning action. The arc-shaped deceleration cushioning member 63 can have a wide range of shapes such as a substantially circular circumference like the receiving cylinder (cyclone) 61 shown in FIG. 6, a poor arc shape as shown in FIG. 5, and other excellent arc shapes. Is. In addition to the arc-shaped member, a plate-shaped collision buffer member having an arbitrary shape can be used instead. Further, 55 is a filter, 56 is a filter cover provided with an exhaust hole, and 57 is an inspection door. Further, a heating means for preventing dew condensation is attached at an appropriate position of the rice grain receiving pipe 53. The heating means is not limited to a special kind or structure such as a general heater or a double pipe using the waste heat of the kitchen.

Next, FIG. 6 shows another embodiment of the rice grain storage container side in the rice grain delivery and receiving device. This example basically has the same function as that of the embodiment of FIG. 4, but the arrangement and the like are slightly changed. That is, in the example shown in the figure, a metering shutter 58 equipped with a weight detecting means and a rice washing / cooking facility 51 are provided at the subsequent stage of the rice grain storage container 52, respectively. Then, the rice grain sent from the transfer hose 9 passes through the rice grain receiving pipe 53, collides from the tangential direction of the circle, and has a cyclone-shaped receiving cylinder 61 having a function as a circular deceleration cushioning member 63, which is continuous with it. The rice grains are finally supplied to the rice grain storage container 52 via the bucket conveyor 60 and the lateral transporting device 59. Reference numeral 62 represents a dust removing device for exhaust gas discharged from the receiving cylinder 61. Although the present embodiment is an example in which the weighing shutter 58 as a weight detecting means is provided at the subsequent stage of the rice grain storage container 52, it may be provided between the receiving cylinder 61 and the bucket conveyor 60, that is, the rice grain storage container 52, if necessary. It may be provided before. In any case, the outer panel 54 may be electrically connected.

Further, the weight detection means on the rice grain storage container 52 side is provided with an output means of the detected weight data, and the mobile rice grain delivery device side is provided with an input means of the detected weight data from the output means, and these output means are provided. It is also effective to connect the input means and the input means with a communication cable or the like to exchange data so as to be useful for controlling the transfer amount of rice grains. Also, wireless communication can be used instead of the communication cable.

Since the present invention is configured as described above, the delivery work of rice grains is roughly as follows. First, on the shipping side of the rice grain distributor, the automobile 1 of the mobile rice grain delivery device is moved to a convenient place, and then the hatch 7 is opened to fill the rice grain tank 5 with rice grains. To do this, it is better to let it flow from the upper storage tank. At this time, the filling amount may be measured. When the filling is completed, close the hatch 7,
Connecting pipe 67 that is attached to the outside of the building 50 of the rice grain receiving and receiving apparatus by driving the automobile 1 to go to the restaurant industry or the like.
, That is, near the rice grain storage container 52. Then, in order to supply the necessary amount of the restaurant, the mouthpiece 10 of the transfer hose 9 mounted on the automobile 1 is connected to the connecting pipe 67. It goes without saying that the caps respectively covering the base 10 and the connecting pipe 67 are removed before that. Further, unlike the case of FIGS. 4 and 6, when the connecting pipe 67 is attached not at the outer wall of the building 50 but at an appropriate position indoors, it is connected to the base 10.

Then, the compressor 3 is driven by the engine of the automobile 1 or another independent prime mover, so that the rice in the rice grain tank 5 moves along with the high pressure air in the transfer pipe 6 and the transfer hose 9 at a speed of less than 6 meters per second. And is finally transferred into the void volume in the rice grain storage container 52. The air at this time is exhausted through the filter 55 or the dust removing device 62. Since the rice grains are supplied to the receiving cylinder 61 and the deceleration cushioning member 63 from the tangential direction of the arc, crushing grains and surface roughening do not occur at an apparent speed of 6 meters or less per second. However net 4.
If the speed is 4 meters or less, the rice grain is not damaged even without the buffer member 63.

The rice is transferred in this manner, but there are some differences depending on the embodiment. That is, of the mobile rice grain delivery devices, the one shown in FIG. 1 is mainly of a total amount transfer type, and the rice in the two rice grain tanks 5 and 5 is transferred until it is empty. On the other hand, the one shown in FIG. 2 is mainly of a small quantity and of a metering transfer type, which measures and delivers the required quantity of the delivery destination. That is, the butterfly valve 17 is opened, the solenoid 11 is energized, and the shutter 12 is raised to fill the rice in the rice grain tank 5 into the rice grain storage tank 14 from the outlet 13 while the load cell 16 serving as a weighing means is filled. The weight is detected by, and at the same time when the required amount is reached, the solenoid 11 is de-energized and the outlet 13 is closed. Then, the butterfly valve 17 is closed and the rice grain storage tank 14 is transferred by high-pressure air until it becomes empty.
If one transfer is not enough, this operation may be repeated.

The one shown in FIG. 3 is also of a small-quantity transfer type, and it is not necessary for both the rice grain tank 5 and the hopper portion 37 to maintain airtightness, and the weighing means 29 weighs until the required amount is reached and is stored in the accommodating portion 31. Discharge. And the rotor 43
The rotation causes the rice to be airtightly dropped and then transferred.

Next, on the rice grain delivery receiving device side, in FIG. 4, the rice sent from the transfer hose 9 of the mobile rice grain delivery device has a base 10 at the tip of the transfer hose 9, a connecting pipe 67, and indoor piping. The rice is transferred to the rice storage container 52 through the rice reception pipe 53. In the subsequent one in FIG. 6, the rice transfer is the same as that in FIG. 4, but the rice transferred to the receiving cylinder 61 passes through the bucket conveyor 60 and the lateral transfer machine 59 and the rice grain storage container 52.
It is dropped inside and transferred. Therefore, the routes to the rice grain storage container 52 are slightly different between the configurations of FIGS. 4 and 6, but it goes without saying that various configurations can be adopted depending on the conditions of the receiving side.

As the weight detecting means, the rice once stored by the rice grain storage container 52 with a load cell in the case of FIG. 4 or the weighing shutter 58 in the case of FIG. Weigh out only the amount you want each time and pay it out. Therefore, in any of the examples, the rice in the rice grain storage container 52 is of the first-in first-out system, and the later-added rice is not consumed first and the quality of the rice is not deteriorated.

[0033]

According to the present invention, the following effects can be obtained by the above-described operation. First, since the rice grains in the tank are pushed out from the vehicle-mounted tank by the air conveying means,
Since it is not necessary to bag rice grains when they are delivered, the manufacturing cost can be reduced, human labor at the time of delivery can be greatly reduced, and dust and the like can be eliminated. Therefore,
This is especially beneficial when using unwashed rice. By optimizing the transfer conditions as described above, the occurrence of broken rice due to the transfer and the roughening of the surface of the rice grain can be eliminated, and the rice grain can be transferred very easily and labor-saving while keeping the quality of the rice grain high. In addition, it will not get wet due to delivery in the rain,
In addition, since it is no longer stored unused for a long period of time, this also contributes greatly to maintaining the quality of rice grains.

Further, a fixed amount of rice grains can be metered out, and only the required amount that has been dispensed is transferred each time, a small amount can be measured and sold, and highly versatile rice grains can be delivered.

On the other hand, in the rice grain delivery / accepting device, since the rice is stored in the upper portion by the rice grain storage container, especially on the receiving side, the above-ground space becomes large and water is splashed during the storage, or the rice is stored behind in the conventional manner. The quality does not deteriorate due to first-in first-out. Furthermore, when rice is cooked, it is possible to save the trouble of carrying and opening the rice bag, eliminating the loss of rice remaining in the empty bag, and eliminating the waste disposal of the empty bag.

As described above, according to the present invention, it is possible to significantly reduce the number of workers on both the delivery and production sites and maintain and improve the quality of rice at a high level.
