Description

Stirring container and automatic cooking server

The present invention relates to an agitating container and an automatic cooking server for obtaining a thick liquid by mixing powder such as water with a thick component.

In recent years, the function of adding various functional materials to beverages has been demanded. And as the functional material to be added to the beverage, in addition to the thickening material for thickening the beverage, a fiber material for adding dietary fiber to the beverage, a protein material for adding protein to the beverage, and adding lactic acid to the beverage. Lactic acid materials.
Among these functional materials, the prevention of aspiration pneumonia caused by dysphagia has become a major social issue, and thus the demand for thickening materials is increasing. Dysphagia is a symptom that tends to occur in old age, and is a condition in which the ability to swallow weakens with age and it becomes difficult to swallow food and drink. Then, aspiration may cause pneumonia, which may lead to nutritional deterioration due to decreased appetite and lack of water.

The food that is most likely to cause aspiration is said to be a drink. The reason is that the drinks are not organized and pass through the throat quickly. Therefore, in order to prevent aspiration, it is effective to thicken the beverage so that the beverage can be easily put together and slow down the passage through the throat.

2. Description of the Related Art Conventionally, when eating and drinking in hospitals, nursing facilities, etc., especially for persons with dysphagia, it has been made to have a thick food.
However, generally, the thickened cooking is mostly done manually for each drink. For this reason, there are problems in that it takes time to measure the thickening raw material and to mix with the beverage, and further, the measurement error due to human's hand and the quality of the finished product vary. Therefore, in view of the above problems, it is desirable to automate the adjustment of thickening.

The inventor of the present invention has verified the means proposed in the prior art for adding these functional materials to beverages. For example, the inventor of the present invention has a prior art that "when a powder and a liquid are stirred and mixed in a stirring container to produce a slurry, 10 to 30% of a required amount of the liquid is frozen to a size suitable for cleaning. The ice pieces, and after the ice pieces and the required amount of the remaining liquid of the liquid are charged into the stirring container, the powder required amount is gradually mixed into the stirring container while stirring and mixing, and the stirring container Stirring of powder and liquid that mechanically cleans the unmixed powder residue that floats near the gas-liquid interface on the inner surface and tends to adhere to it and collects it in the slurry and dissolves the ice fragment in the slurry "Slurry production apparatus by mixing" (see Patent Document 1) was tried.

JP-A-2-241531

As a result of verifying the stirring and mixing device according to Patent Document 1, when the viscosity is high and a thickened beverage having a volume of 2 liters or more is required, vortexing does not occur even if the volume is stirred and mixed, and a liquid required amount of 10 It has been found that thick mixtures cannot be easily made even without freezing ~ 30%.
This is because when the thickening hardens, the stirring blade stops without rotating. In order to avoid this, it is conceivable to increase the rotational power, but the configuration including a stronger power source tends to be expensive. Further, it was discovered that even if the rotational power was simply increased, the stirring blades were rotated, but the materials were not mixed. This is because the thickened viscosity increases, but the area around the stirring blade rotates, but the rotary stirring in the entire container stops, and as a result, the whole is not mixed synchronously, and mixing and stirring in the container progress substantially. It was confirmed that this is a phenomenon that does not occur.

Therefore, an object of the present invention is to provide a stirring container and an automatic cooking server for solving the above problems.

In order to solve the above-mentioned subject, one of the typical embodiments of the present invention is a stirring container described in claim 1, and is as follows.

As the types of functional materials, as described above, in addition to thickening materials for thickening beverages, fiber materials for adding dietary fibers to beverages, protein materials for adding proteins to beverages, and lactic acids for beverages. There are lactic acid materials to add.
In the following disclosure, a case where a thickener is added as an example of a functional material using the stirring container and the automatic cooking server of the present invention will be described. However, the stirring container and the automatic cooking server of the present invention are not limited to the application to the thickened material, and also applied to the stirring of other functional materials such as fiber material, protein material, lactic acid material and other raw materials. It goes without saying that it is possible.
First, the definition of a thickened beverage and the main requirements are explained as follows.
<1. Definition of thickening>
Regarding the thickening liquid for persons with dysphagia, the Japanese Society for Eating and Swallowing Rehabilitation shows three-level thickening classification in "Japanese Society for Eating and Swallowing Rehabilitation Swallowing Adjusted Diet Classification 2013", and in the present disclosure. Also describe according to the classification.
The criteria of the above-mentioned three stages are "Stage 1 Mildly thick", "Stage 2 Moderately thick", and "Stage 3 Extremely thick".

Stage 1 The thin thickening has a viscosity of 50-150 (mPa · s) and an LST value of 36-43 (mm). In addition, the thickening in the middle of stage 2 has a viscosity of 150-300 (mPa · s) and an LST value of 32-36 (mm). Furthermore, the thick and thickened grade 3 has a viscosity of 300-500 (mPa · s) and an LST value of 30-32 (mm). Here, the viscosity is a viscosity measurement result after 1 minute at a measurement temperature of 20 ° C. and a shear rate of 50 s ⁻¹ using a cone-plate type rotational viscometer. In addition, the LST value is 20 ml of a sample injected into a metal ring having an inner diameter of 30 mm using a plastic measuring plate for a line spread test, the ring is lifted after 30 seconds, and the spread distance of the sample is measured at 6 points after 30 seconds. Let the average value be an LST value.

<2. Thick material>
As a raw material for thickening a liquid (thickening material), there are mainly three types of starch type, guar gum type, xanthan gum type, but the thickening material used in the present disclosure is a polysaccharide. It is a certain xanthan gum-based material.

<3. Expression of thickening>
The xanthan gum-based thickening material has a transparent feeling, low adhesion, and cohesiveness. It also has the characteristic that it has little taste and odor.
Then, when xanthan gum is mixed into the beverage, it absorbs water and swells, so that the beverage can be thickened by stirring and diffusing it uniformly in the beverage. Therefore, it takes a certain amount of time for the swelling and stirring to stabilize the thickening of the beverage.
In addition, the strength and time of stirring, the nature of the beverage (whether milk components or acids are present, etc.), the size of the thickening component dispersed in the beverage depending on the temperature, the degree of thickening that can be achieved, and the time until the thickening stabilizes vary. Change. Therefore, in order to achieve a desired degree of thickening for many types of beverages, it is necessary to make adjustments according to the respective beverages.
In addition, the degree of difficulty in thickening beverages differs depending on the type of beverage, and it has been considered extremely difficult to thicken milk in particular. In the past, thickening was performed manually by humans, so it was almost impossible to thicken milk. However, by using the stirring container and the automatic cooking server of the present disclosure, it becomes possible to give proper thickening to milk. As a result, it is possible to provide milk that has been thickened with peace of mind to elderly people while preventing aspiration.

<4. Properties of thickened beverages required to prevent aspiration>
The temperature of the beverage is required to be in the temperature range of 3 ° C to 65 ° C for hot beverages and cold beverages. For thickened warm beverages, it is more difficult to cool compared to normal beverages, so there is a risk of burns if a hot beverage is provided, so (A) the upper limit of the beverage temperature provided is 65 ° C, preferably about 45 ° C. Is.
Also, for cold beverages, the absence of ice in the cup is required. This is because the presence of ice in the cup may induce aspiration when swallowing the ice. For this reason, no ice remains in the beverage provided (B), and the beverage temperature is 3 ° C to about 65 ° C.
Furthermore, in order to prevent aspiration, the viscosity of the beverage (C) is required to be uniform and temporally stable.

An embodiment of the present invention will be described below with reference to the drawings. As described above, the invention according to the embodiment of the present disclosure is a thickening and stirring container in which protrusions facing each other are provided on the inner wall surface, and the stirring container is used to stir and mix powder and liquid, It relates to an automatic cooking server that thickens and cooks liquids.

1 is a schematic perspective view showing an embodiment of the present invention, and FIG. 2 is a schematic sectional view showing an embodiment of the present invention. 1 and 2 show the configuration of a stirring container for cooking thickened beverage by stirring and mixing thickening powder and liquid for thickening.

As mentioned above, in the past, caregivers used to manually mix thickened beverages by manually stirring them, but this requires caregivers' time, as well as measurement errors by human hands and quality of finished products. There was a problem such as the possibility of variations in Therefore, the present invention aims to solve these problems by providing an agitating container provided with protrusions facing each other on the inner wall surface and an automatic cooking server that automates agitating and mixing using the agitating container. I am trying.

Here, a specific example of the configuration of the present invention will be described in detail.
First, as shown in FIGS. 1 to 4, the stirring container 1 may be, for example, a plastic cylindrical container having a size capable of cooking a volume of 2 liters. Although a container having a capacity of 2 liters is shown here as an example, the present invention is not limited to this, and may be, for example, a container having a capacity of 500 milliliters or a capacity of 10 liters. May be selected. Needless to say, when the volume of the stirring container 1 is changed, each component forming the stirring container 1 is proportional to the size of the stirring container 1.

As shown in FIG. 1, the stirring container 1 has a spout 5 near the upper opening for guiding the stirred liquid to another container. The spout 5 has a triangular shape protruding outward from a substantially circular upper opening. When the stirring container 1 is viewed from above, the length of the triangular base (the bottom of the spout) is 10% to 1.5% of the length of the circumference of the opening of the stirring container 1. Good. Further, the height of the apex of the triangle (the spout height) of the portion where the spout 5 projects from the upper opening of the stirring container 1 is 10% to 2 of the diameter of the upper opening of the substantially circular stirring container. It may project with a split length.
When pouring a liquid from the stirring container 1 using such a relatively large pouring port 5 into another container, even a highly viscous liquid is not solidified in the vicinity of the pouring port 5 and the target is smoothly fed. Flowing into the container.

As shown in FIG. 3, an auxiliary blade 4 having a low height is provided in the center of the bottom portion of the stirring container 1 in the vicinity of the central axis. Here, the expression “the height is low” means that the height of the auxiliary blade 4 is about half or less of the height of the stirring blade 3 described later.
These auxiliary blades 4 may be arranged separately from the stirring blade 3 as shown in FIG. 3, or may be formed integrally with the stirring blade 3 as shown in FIG. However, it is desirable that the auxiliary blade 4 and the stirring blade 3 are integrally formed from the viewpoint of the uniformity of the stirring target that is stirred in the stirring container 1.

The main stirring blade 3 is provided on the outer peripheral side of the auxiliary blade 4 with a gap (for example, 10 mm) into which a finger can be inserted for cleaning. The height of these stirring blades 3 may be 10% to 20% of the total height of the stirring container 1. For example, when the height of the stirring vessel 1 is 200 mm, the height of the stirring blade 3 is preferably about 20 to 40 mm, and more preferably about 25 to 35.

As shown in FIG. 6, one or more sets of even-numbered container-side magnets 9 are provided radially opposite each other on the bottom of the stirring blade 3 (FIG. 6 shows two sets of four container-side magnets). 9 shows an example in which 9 is provided).
In the example shown in FIG. 6, the container-side magnet 9 is provided with a cover portion that can be positioned at the bottom of the stirring container 1 and is externally mounted in the cover portion. Since 1 is made of resin, the container-side magnet 9 may be integrally embedded in the bottom portion and may not come off.

Further, as shown in FIGS. 1 and 2, the stirring container 1 is formed with a projection 2 integrally formed on the inner wall side so as to project from the outside to the inside. The protrusion 2 may be provided, for example, at one location on the inner wall surface of the stirring container 1 (that is, the first inner wall surface), or at a plurality of locations (for example, on the first inner wall surface and the first inner wall surface). It may be provided on the opposing second inner wall surface).

The shape of the protrusion 2 is about ⅓ downward from the upper opening from the bottom to the top of the stirring container 1 (this may be appropriately selected depending on the degree of thickening, the liquid to be stirred and mixed, the volume, etc.). A part may be provided.

Further, the protrusion 2 may have, for example, a shape in which the upper portion is sharpened in a mountain shape. When stirring and mixing is performed using the stirring container 1 provided with such a mountain-shaped protrusion 2, the object to be stirred goes back up the mountain-shaped slope of the protrusion 2, is lifted, and flows back to the central portion. Therefore, it is possible to prevent the objects to be mixed from staying at the outer peripheral portion. As a result, the object to be mixed is sufficiently agitated even in the vertical direction in the container, and a uniform thickening liquid that does not cause fooling can be obtained.
It should be noted that although the configuration in which the upper portion of the protrusion 2 is mountain-shaped is shown as an example, the present invention is not limited to this, and it is possible to prevent the stirring object from staying in the outer peripheral portion, and the central portion. Any shape may be used as long as it can be returned to and continuously stirred. For example, the upper portion may not have a bilaterally symmetrical mountain shape, but may have a bilaterally asymmetrical mountain shape, or only one of the left and right sides may be formed as a slope.

Further, as shown in FIGS. 1 and 2, the stirring container 1 is provided with a loss preventing locking groove 13 for the fastener 12. The loss prevention locking groove 13 is a groove for accommodating the fastener 12 for fixing the stirring blade 3. With this configuration, when the fastener 12 of the stirring blade 3 is unfastened, for example, when the stirring blade 3 is washed and the stirring blade 3 is removed and washed, the fastener 12 is stored in the loss prevention locking groove 13. Thus, the fastener 12 can be prevented from being lost.
The fastener 12 may be, for example, a cap nut, a normal nut or the like, and may be any fixing member as long as it is hard to remove and can be easily fixed.

In the above, the embodiment in which the protrusion 2 is integrally formed is shown, but the present invention is not limited to this. For example, it is possible to adopt a configuration in which the protrusions 2 made separately are provided inside the stirring container 1 so as to face each other in the radial direction.

Further, as shown in FIG. 5, a motor 6 serving as a rotation drive source of the stirring blade 3 is provided in the lower portion of the stirring container 1. The motor 6 is also provided with a server-side magnet 7. The container-side magnet 9 provided below the stirring blade 3 is coupled to the server-side magnet 7 by a magnetic coupling to rotate the stirring blade 3.
In addition, in the embodiment shown in FIG. 6, the container-side magnet 9 has a configuration in which four rod-shaped magnets are provided so as to face the outer peripheral side from the center, but the present invention is not limited to this configuration. The shape may be a disk shape, and the number may be changed appropriately. However, as a result of actually making a prototype and testing it, it is desirable to have a configuration in which four rod-shaped magnets are provided, because it rotates smoothly and can be obtained at a low price.

As shown in FIG. 5, the automatic cooking server is provided with a container base 10 that supports the stirring container 1. In addition, the container base 10 is provided with a stirring container positioning portion 11 that fixes and supports the stirring container 1.
Needless to say, the size of the gap between the server-side magnet 7 provided on the motor 6 and the bottom of the container base 10 should be the minimum design.
Further, by adopting a motor as a drive source, it becomes easy to control the automatic cooking server, and it is possible to easily control the rotating force, the rotating speed, ON-OFF and the like.

Next, the front door of the automatic cooking server of the present invention will be described with reference to FIGS. 7 to 9.
It should be noted that the color of each operation button is white for easy confirmation in the drawing, but in reality, the color of each operation button of the automatic cooking server may be appropriately selected.

When the automatic cooking server is in the standby state, each operation button is turned off, and when it is ready for sale / ready, the lamp provided on the operation button is turned on. When the stirring container 1 is set inside the automatic cooking server and the door for putting the stirring container 1 in and out is closed, all the lamps provided on the operation buttons are turned on. At that time, in the lamp provided on the operation button, the button pressed after the button is operated blinks and the other buttons are turned off.

The button pressed after the completion of cooking lights up to notify the completion of cooking. Further, when the stirring container 1 is removed, all the lamps provided on each button are turned off.
It goes without saying that a switch for detecting that the door for putting in and taking out the stirring container 1 is closed is provided.

The operated operation button is turned on after input, and is turned off after the stirring container 1 is taken out or when cooking is canceled.
It should be noted that this canceling operation may be canceled by operating the cleaning button 26 twice in succession, or may be canceled by pressing the cleaning button 26 for a long time.
When the stirring container 1 is taken out, the washing / water supply operation button is programmed using a timer so as to operate after a certain period of time has elapsed.
It is possible to cancel before the timer is activated.

In addition, as an example of an operation flow for extracting each beverage to be obtained, the automatic cooking server of FIG. 7 will be described as an example.
(1) In the case of thickening only, select the degree of thickening with the thickening (large / medium / small) button and extract.

(6) In the case of only hot water, the operation can be performed only by pressing the operation button of the hot water while the safety switch is in the off state.
(7) It should be noted that the raw material is not necessarily charged into the stirring container by the automatic cooking server. It is also possible to set individual materials (eg miso soup, milk, etc.) to the stirring container in advance and press the corresponding selection button to set the stirring of only the previously-prepared materials and thickener. ..
(8) When cleaning is performed, the cleaning is performed by pressing only the cleaning operation button.
(9) When supplying water, water is supplied by selecting and pressing the operation button for water supply.
Although the operation flow of one example of the operation button has been described above, it is possible to provide a beverage in accordance with the user's request by making detailed setting changes such as a beverage recipe and the like on each of the operation buttons. .. As a result, it is possible to individually set the cooking of the commercial material to be used for each button in a hospital, a nursing facility, or the like.
