Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention provides an optical method for measuring the taste of cooked rice, that is, rice that has been cooked into rice.
It relates to a device for making a sample to be subjected to the optical measuring machine.

<Prior Art> A method for measuring the taste of cooked rice by an optical method has already been proposed by the present inventor (Japanese Patent Application No. 1-113172). In this eating quality measuring method, the cooked rice is irradiated with a light beam, the reflected light thereof is measured through a polarizing filter, and the eating quality is obtained from the light quantity value.

<Problems to be Solved by the Invention> When the taste of cooked rice is measured by the above method, the problem is how to prepare a sample for application to an optical measuring machine.
First, the cooked rice to be measured must be placed in a sample container, but at this time, the top surface of the placed cooked rice group must be a flat surface without irregularities. Because
At the time of measurement, light is emitted from an oblique direction, and reflected light is received on the opposite side for measurement, so if there is unevenness on the mounting surface, it will have a great effect on the reflection effect, and the amount of reflected light will fluctuate, resulting in an accurate measurement. The taste cannot be measured. In addition, the optical taste measurement is to obtain the taste from the water retention status of the surface layer of cooked rice grains, and the water retention structure of the rice grain surface has a thin layer that can be called a water retention film on the rice grain surface. ,
Since water is stored there, if the water retaining layer is damaged during arranging work, accurate measurement will not be possible.

As described above, in the measurement of the eating quality by the optical method, it is very important to maintain the condition of the surface layer of the cooked rice grain, and in order to improve the measurement accuracy, it does not adversely affect the water retention condition of the surface of the rice grain, and always It is necessary to carry out uniform and uniform arrangement.

In view of such a point, the present invention provides a sample manufacturing device for measuring the taste of cooked rice that can be always placed in a constant state without a bad influence on the surface of the rice grain by a simple operation that can be performed by any person. To do.

<Means for Solving the Problems> The technical means of the sample manufacturing apparatus of the present invention comprises a sample container and a filling tool, and the sample container has a container body having at least one open surface, and the opening. The filling tool includes a guide tube that can be fitted into the container body, and a holding body that can be fitted into the guide tube and has a projecting portion on the outer peripheral edge. When filling the cooked rice, the guide tube is used by inserting it into the open surface of the container body with the lid removed. It is intended to be used for the primary shaping of surfaces.

<Operation> In the sample manufacturing apparatus of the present invention, the container body and the lid are detachable. The container body is placed horizontally with the lid on one side removed, and the guide tube is inserted into the container body. Next, the cooked rice in a predetermined amount is put into the guide tube. Then, when the pressing body is placed on this and pressed down, the cooked rice grains are pushed and moved, and the surface of the serving is first shaped. Since the guide plate is taller than the container body and has a protruding portion at the periphery of the pressing body, this pressing can be performed without the rice grains protruding laterally. In this primary shaping, the shaping surface is shaped according to the shape of the lower surface, so that the shaping surface has a horizontal flat surface in the central portion, but the peripheral portion is an inclined surface, and is generally frustoconical. . After that, the guide plate and the pressing body are removed, the cover is applied instead, and the pressing is performed again. As a result, the cooked rice is completely filled in the container body,
Moreover, the surface of the plate after removing the lid becomes a completely flat surface, which is convenient for optical measurement.

<Example> An example of the sample manufacturing apparatus of the present invention will be described with reference to the drawings. A sample container 1 is composed of a container body 2 and a lid 3. The container body 2 is an annular frame body having an inner diameter of about 80 mm and a thickness of about 8 mm. The lid 3 is applied to both front and back surfaces of the container body 2 to form the sample container 1. An O-ring 4 is provided on the surface of the container body 2 that contacts the lid 3 to prevent water from flowing out from the joint between the container body 2 and the lid 3. It is preferable that the inner surface of the lid 3 be coated with a fluorine-based synthetic resin (trade name, Teflon) or the like so that it does not easily stick to the cooked rice. The container body 2 is provided with holes 5 for water passage and ventilation at least at two locations above and below.
6 is a handle attached to the container body 2, and 7 is a stopper for fixing and locking the lid 3. A plurality of stainless steel wire rods 8 are stretched in the container body 2. The wire 8 plays a role of preventing the rice from falling out of the container body 2 when the upper and lower lids are removed, and a role of a stopper when the filling tool described later is inserted.

Reference numeral 10 is a cooked rice filling, which comprises a guide tube 11 and a pressing body 12.
The guide tube 11 is a thin cylindrical body made of plastic or the like and having a thin wall thickness. The diameter of the guide tube 11 is slightly smaller than the diameter of the container body 2 and can be provided inside the container body 2. The pressing body 12 has a circular shape and can be inserted into the guide cylinder 11, and a handle 13 is attached to the upper surface thereof. Further, the lower surface of the pressing body 12 has a flat surface 14 at the central portion thereof, but an annular protruding portion 15 is formed at the peripheral edge thereof. That is, the pressing body 12 has a shape having a truncated cone-shaped depression on its lower surface.

Next, a method of using the device will be described. First, the fourth
As shown in the figure, the container body 2 is placed on the one lid 3, and the guide cylinder 11 is inserted into the container body 2. Next, the cooked rice A measured in a predetermined amount is put in this. The amount of rice to be stored in the container body 2 is determined according to its internal volume, and in the embodiment, it is 45 g.
Is. Then, the presser body 12 is inserted into the guide tube 11, and the cooked rice A is pressed from above. At this time, the maximum pushing positions of the guide cylinder 11 and the pressing body 12 are regulated by the wire rod 8, so that the wire rod 8 may be pushed fully until it collides with the wire rod 8. As a result of this pushing, the cooked rice A is in a pressed state and is primary shaped as shown in FIG. However, in this primary shaping state, the central portion is flat, but the peripheral portion is the protruding portion 15.
Therefore, it is a chamfered inclined surface. Next, the presser body 12 and the guide cylinder 11 are removed, and the other lid 3 is applied to the surface of the plate and further pressed. As a result, the cooked rice spreads over the container body 2 and is in a completely filled state with no space. Next, the lids 3 on both sides are fixed by the stoppers 7 so as not to come off, and the sample container 1 is immersed in boiling water (about 70 to 100 ° C.) in a state of containing cooked rice. After 3 minutes, remove from hot water, let cool for 3 minutes, and then cover 3
Remove. This makes it possible to obtain a sample in which the cooked rice A is filled in the container body 2 cleanly. Then, this is applied to an optical measuring device to measure the taste.

The immersion in boiling water is for eliminating the restoration of cooked rice. Cooked rice has a strong restoring force, and the flattening and shaping of the surface is not enough by simply pressing it, and when the lid is removed, the central portion rises again and is restored and deformed. However, in the case of freshly cooked rice, since the fluidity between rice grains is high and the restoring force is small, surface shaping can be done by just pressing,
In this case, hot water immersion is unnecessary.

In the present invention, the specific shapes of the filling tool 10 and the sample container 1 are not limited to the examples, and the design can be freely changed within the range where the purpose can be achieved.

<Effects of the Invention> With the sample manufacturing apparatus of the present invention, a sample can be prepared by a simple operation that anyone can do without adversely affecting the surface state of rice grains of cooked rice. Further, in the present invention, the surface to be coated becomes a clean flat surface, which is convenient for optical measurement, and anyone can always prepare a sample in a constant state. In addition, rice grains can be placed without leaking, and uneven measurement due to fluctuations in the amount of rice contained can be prevented. Therefore, if optical measurement is performed using a sample produced by the device of the present invention, it is possible to obtain a highly accurate and universal taste measurement result.
