Description

  The present invention comprises an agitation means for agitating the inside of a storage tank for generating a coating material solution, and a heating means for heating the inside of the storage tank, and starch supplied to the storage tank, a quality improver, and Further, the present invention relates to a coating material solution generating apparatus configured to generate a coating material solution for covering rice grains by stirring and mixing water and heating and dissolving starch and a quality improver and storing them in the storage tank.

  The coating material solution generating apparatus having the above-described configuration is, for example, a method for forming a coating material solution for coating rice grains in order to produce washable rice by forming a film on the surface of rice grains from which all or almost all of the paste powder layer has been removed. This type of coating material solution generator is used for washing rice, and has conventionally been configured as follows.

  That is, in the case where the coating solution is generated in a state containing starch and a nutrition enhancer as an example of a quality improver, the stirring means acts as a stirring action at the upper and lower intermediate positions of the storage space in the storage tank. And stirring and mixing the starch, quality improver, and water supplied to the storage tank in this one stirring action unit, and the starch and the quality improver inside the storage tank by heating means Was dissolved to produce a coating solution (see, for example, Patent Document 1).

  In addition, although the said patent document 1 does not describe about the heating means for heating and melt | dissolving starch and a quality improvement agent, the structure which supplies a heater or high temperature steam, etc. dissolve starch and quality improvement agent. Therefore, a heating means for heating the inside of the storage tank is required for gelatinization. In addition, the above-mentioned Patent Document 1 does not describe a specific configuration for supplying starch and a quality improver to a storage tank, but it is automatically supplied using a supply device or manually performed by an operator. It is supplied by work or by any method.

Japanese Patent Publication No.51-194

  In the above conventional configuration, when the starch, quality improver, and water supplied to the storage tank are stirred and mixed, and the starch and quality improver are dissolved inside the storage tank by the heating means, storage is performed. Since the agitation is performed by one agitation operation portion provided at the upper and lower intermediate positions in the storage space in the tank, there are the following disadvantages.

  That is, the starch used to produce the above-described rice grain coating material solution has a property that it has a higher specific gravity than water and is likely to settle downward while stirring and mixing in the coating material solution. However, in the above-described conventional configuration, since the stirring action portion is provided at the upper and lower intermediate positions in the storage space, the stirring function by the stirring means may not be sufficiently exhibited in the lower side portion near the bottom in the storage space. . As a result, starch may precipitate in the vicinity of the bottom of the storage space and stay in a solid powder form.

  In producing the above-described coating material solution for rice grain coating, it is preferable that the starch concentration used for the rice grain coating is produced at an appropriate concentration in order to properly form the rice grain coating. In other words, if the starch concentration is lower than the appropriate concentration, the viscosity of the coating solution is lowered, and the addition adhesion to the surface of the rice grain is not performed well, and the formation of the rice grain coating may not be sufficiently performed. In the above conventional configuration, even if a set amount of starch is supplied to the storage tank so that the starch concentration of the coating material solution becomes an appropriate concentration, a part of the starch settles near the bottom of the storage space in the storage tank. Then, it may remain in a solid powder state and may not dissolve, and as a result, the starch concentration of the coating material solution may be lower than an appropriate concentration, and the rice grain coating may not be sufficiently formed.

  On the other hand, the quality improver used in the coating material solution for coating rice grains generally has a property that the specific gravity is smaller than water and tends to float on the surface of the coating material solution. Since the stirring action part is provided at the upper and lower intermediate positions in the storage space, the stirring function by the stirring means may not be sufficiently exhibited in the upper side portion in the storage space. As a result, the quality improver floats on the surface in the upper portion of the storage space, and may remain in a solid powder form and remain. In other words, since the quality improver is not sufficiently dissolved in the coating material solution and remains in the form of a solid powder, the concentration of the quality improver in the coating material solution may be lower than the appropriate concentration. .

  As a result, even when an appropriate amount of starch and an appropriate amount of quality improver are supplied to the storage tank, the starch and the quality improver remain in a solid powder form inside the storage tank as described above. And the starch concentration of the resulting coating solution is different from the preset value, and the rice grain coating is suitable for coating the rice grains without the concentration of the quality improver being appropriate. There was a possibility that the coating material solution could not be produced.

  Therefore, in order to eliminate such disadvantages, the quality improver is dissolved in advance by another device as a configuration in which one stirring action portion in the stirring means is positioned in the lower portion of the storage space in the storage tank. Although it is conceivable to supply the storage tank later, such a configuration requires another device for dissolving the quality improver, which is disadvantageous in that the configuration becomes complicated and the cost is increased.

  In addition, in the coating material solution generating apparatus as described above, when starch and a quality improver are supplied to the storage tank, an appropriate amount of starch is added to the storage tank in order to generate an appropriate rice grain coating material solution. And an appropriate amount of quality improver must be supplied. In other words, even if the stirring action by the stirring means in the storage tank is sufficient, if the supply amount of starch to the storage tank and the supply amount of the quality improver to the storage tank are not properly controlled, The concentration does not become an appropriate concentration, and the quality improver cannot be made an appropriate concentration.

  In the above conventional configuration, the configuration for supplying starch and quality improver is not described, but for managing the supply amount of starch to the storage tank and the supply amount of quality improver to the storage tank to be appropriate. As a configuration of, for example, it is conceivable to supply each of the supply amount of starch and the supply amount of the quality improver while accurately managing based on the weight measurement result, but with such a configuration, There is a disadvantage that the configuration of the entire apparatus is complicated and the cost is increased, for example, a plurality of apparatuses for measuring the weight and a plurality of apparatuses for managing the supply amount based on the weight measurement result are required.

  Further, as another configuration, one weight measuring means can be switched to a state in which the measurement state of one weight measuring means can be switched between a state in which the weight of starch is measured and a state in which the weight of the quality improver is measured. It is conceivable to share the quality improver, but in such a case, switching to enable the supply of solid starch and the quality improver separately to the weight measuring means is possible. There is a disadvantage that the structure is required and the configuration is complicated.

  Therefore, while suppressing the increase in cost as simple as possible, the starch concentration becomes an appropriate concentration suitable for the coating of rice grains, and the quality improver has an appropriate concentration to cover the rice grains. There has been a demand for a coating material solution generating apparatus that can generate a coating material solution for covering rice grains that is suitable for the above.

  An object of the present invention is to provide a coating material solution generating apparatus capable of generating a coating material solution for covering rice grains while suppressing an increase in cost as a simple configuration as much as possible. The point is to provide.

  The first characteristic configuration of the present invention is provided with a stirring means that stirs the inside of a storage tank for generating a coating material solution and a heating means that heats the inside of the storage tank, and starch supplied to the storage tank, A coating material solution generator configured to generate a coating material solution for rice grain coating by stirring and mixing water, and heating and dissolving starch and the quality improving agent, and storing them in the storage tank. The agitating means agitates the upper side portion of the storage space in the storage tank, and the lower side agitation operation portion that agitates the lower side portion of the storage space in the storage tank. It is in the point comprised with.

  According to the first characteristic configuration, the starch, the quality improver, and the water that are supplied into the storage tank by the stirring means, and the stirring and mixing of water, and the starch and the quality improving agent by the heating means are dissolved by heating. A coating solution for coating will be produced. And since the said stirring means is comprised including the upper side stirring action part and the lower side stirring action part, the lower side stirring action part will stir the lower side part of the storage space in a storage tank. In addition, the starch can be dissolved in the coating solution by the stirring action by the lower stirring action section without the starch being precipitated at the bottom of the storage tank. On the other hand, since the upper stirring portion of the stirring means stirs the upper side portion in the storage space, the quality improver supplied to the storage tank is not stirred and remains on the upper side. It can be dissolved in the coating solution by the stirring action by the action part.

  As a result, it is possible to adjust the starch concentration to an appropriate concentration by dissolving the starch in the coating solution without precipitating it as a solid powder inside the storage tank. By dissolving in the coating material solution without remaining as it is, the quality improver can be adjusted to an appropriate concentration.

  And according to this 1st characteristic structure, as above-mentioned, it is possible to make the density | concentration of starch into an appropriate density | concentration, and also the advantage that it becomes possible to make a quality improver into an appropriate density | concentration, This is obtained by a simple configuration in which the stirring means is configured to include an upper side stirring action part and a lower side stirring action part. In other words, the upper side stirring action part and the lower side stirring action part in the stirring means as described above can be configured by, for example, stirring blades rotated by driving means such as an electric motor. Since it has a simple configuration, it is possible to suppress an increase in cost.

  Accordingly, it is possible to provide a coating material solution generating apparatus that can generate a coating material solution for rice grain coating suitable for coating rice grains while suppressing an increase in cost as simple as possible. It was.

  The second characteristic configuration of the present invention comprises a stirring means for stirring the inside of the storage tank for generating the coating material solution and a heating means for heating the inside of the storage tank, and starch supplied to the storage tank, A coating material solution generator configured to generate a coating material solution for rice grain coating by stirring and mixing water, and heating and dissolving starch and the quality improving agent, and storing them in the storage tank. A starch supply means for supplying starch to the storage tank; and a quality improver supply means for supplying a quality improver to the storage tank. The starch is supplied to the storage tank in a state where the supply amount of starch supplied to the storage tank is controlled by weight, and the quality improver supply means supplies the quality improver to unit time. It is configured to supply the quality improving agent to the storage tank in a state where the supply amount of the quality improving agent supplied to the storage tank is managed during the supply operation time of the supply means for supplying the set supply amount each time. It is in.

  According to the second characteristic configuration, the rice grains are coated by stirring and mixing the starch, quality improver, and water supplied into the storage tank by the stirring means, and by heating and dissolving the starch and quality improving agent by the heating means. Will produce a coating solution. And, the starch is supplied to the storage tank by the starch supply means. At that time, the starch supply means measures the weight of the starch by the weight measurement means and manages the supply amount of the starch by the weight. The starch will be supplied to the storage tank. That is, since the supply amount of starch supplied to the storage tank is controlled by weight and supplied to the storage tank, changes in the supply amount of starch are monitored in a precise state as changes in weight. It is possible to accurately manage the amount of starch supplied to the tank, and as a result, an appropriate amount of starch can be accurately supplied to the storage tank.

  On the other hand, the quality improver supply means supplies the quality improver while managing the supply amount of the quality improver supplied to the storage tank during the supply operation time of the supply means for supplying the quality improver at a set supply amount per unit time. It will be supplied to the storage tank. That is, since the supply means supplies the quality improver by the set supply amount per unit time, the supply amount of the quality improver supplied to the storage tank can be managed during the supply operation time of the supply means. is there.

  As a result, the starch concentration can be adjusted to an appropriate concentration by supplying an appropriate amount of starch to the storage tank while accurately managing the starch so as to have an appropriate concentration for covering rice grains. In addition, the quality improver is supplied to the storage tank while managing the supply amount during the supply operation time by the supply means that can supply the set supply amount per unit time. It becomes possible to do. Starch needs to have an appropriate concentration to form a rice grain coating well, but quality improvers do not affect the viscosity to form a coating so much, so the concentration accuracy is not so high compared to starch. It may be.

  And since the said quality improving agent does not need to have the precision of a density | concentration so high compared with starch as mentioned above, the supply means with which a quality improving agent is supplied to a storage tank supplies per unit time. High accuracy is not required for the supply amount. As a result, as the supply means for supplying the quality improver to the storage tank, for example, a vibration feeder or the like that is not so high in accuracy but can be used with a simple configuration can be used. It becomes possible to make it.

  Accordingly, it is possible to provide a coating material solution generating apparatus that can generate a coating material solution for rice grain coating suitable for coating rice grains while suppressing an increase in cost as simple as possible. It was.

  In addition to the second feature configuration, the third feature configuration of the present invention includes a holding state in which the starch supply means holds the supplied starch and a hold release state in which the starch being held is supplied to the storage tank. The relay holding container which can be switched is provided, and the weight measuring means is provided in a state of performing a measurement action on the relay holding container.

According to the third characteristic configuration, the starch can be held by the relay holding container in a state where the relay holding container is switched to the holding state, and is retained when the relay holding container is switched to the holding release state. Starch is supplied to the storage tank, but there is a weight measuring means that acts on the holding container for relay, so based on the measurement result of the weight measuring means, the starch to be supplied to the storage tank The supply amount can be managed.
For example, when the starch is not held in the relay holding container, the weight of the relay holding container is measured by the weight measuring means, and the starch is held in the relay holding container. If the weight of the holding container and the weight of the starch held in the relay holding container are measured, the weight of the starch supplied to the storage tank can be obtained from the difference between the detected values. It is possible to manage the amount of starch supplied to the storage tank.

  Then, the above-described relay holding container is switched to the holding state to hold the starch, and the relay holding container is switched to the holding release state to supply the retained starch to the storage tank. Accordingly, it is possible to supply starch to the storage tank in small portions. And it becomes possible to manage the supply_amount | feed_rate of starch with a sufficient precision by measuring the weight of starch with the said weight measurement means, and managing based on a weight.

  That is, the coating material solution is often consumed in a large amount, and the storage tank is generally composed of a large tank in order to produce such a large amount of the coating material solution. On the other hand, the amount of starch required for the large amount of water stored is increased. However, if a large amount of starch is weighed at once, it is necessary to use a large weight measuring means for measuring a large weight with a relatively large measurement error. On the other hand, as described above, a small weight measuring means for measuring a small weight with a small measurement error by adopting a structure that acts on the holding container for relay that can be supplied in small portions in small quantities as described above. This makes it possible to accurately measure the weight of starch.

  According to a fourth characteristic configuration of the present invention, in addition to the third characteristic configuration, the starch supply means can be switched between a supply state for supplying starch to the relay holding container and a supply stop state for stopping the supply of starch. Starch supply state switching means, water supply state switching means capable of switching between a water supply state for supplying water to the relay holding container and a water supply stop state for stopping the supply, and a relay for agitating the inside of the relay holding container A stirring means, and in a state of supplying starch and water at different timings to the relay holding container, the target supply amount of starch is determined by weight based on the measurement information of the weight measurement means. The starch is controlled and supplied to the relay holding container, and the target water supply amount is controlled by weight based on the measurement information of the weight measuring means and supplied to the relay holding container. Supply status The relay agitation is performed so that the starch aqueous solution generated by agitating and mixing the water and starch supplied to the relay holding container is supplied to the storage tank. And the relay holding container is operated.

  According to the fourth characteristic configuration, when the starch supply state switching means is switched to the supply state and the starch is supplied to the relay holding container, the weight measurement is performed on the relay holding container. The weight of starch supplied to the relay holding container is measured based on the measurement result of the means, and it is determined whether the target supply amount of starch is supplied to the relay holding container based on the weight measurement result. When the target supply amount of starch is supplied, the starch supply state switching means is switched to the supply stop state, whereby the target supply amount of starch is controlled by weight and supplied to the relay holding container. can do.

  Further, when the water supply state switching means is switched to the water supply state at a timing different from the supply timing of the starch and water is supplied to the relay holding container, the relay is used based on the measurement result of the weight measuring means. It is possible to measure the weight of the water supplied to the holding container and determine whether or not the target water supply amount has been supplied to the relay holding container based on the result of the weight measurement. When the water is supplied, by switching the water supply state switching means to the water supply stop state, the target water supply amount of water can be managed by weight and supplied to the relay holding container. In this way, starch and water can be supplied while accurately managing based on weight measurement, so it is possible to supply an appropriate amount of starch so that it has an appropriate concentration for rice grain coating, and an appropriate starch concentration. It becomes possible to make it.

  Then, the water and starch supplied to the relay holding container are stirred and mixed by the relay stirring means to generate an aqueous starch solution, and the starch aqueous solution is supplied to the storage tank. It is possible to produce an aqueous starch solution. In addition, if starch is added to preheated high-temperature water and dissolved, the starches adsorb each other and become so-called dumplings, which may not result in a uniform concentration of starch solution. As described above, water and starch are stirred and mixed in advance in a relay holding container to produce an aqueous starch solution, and the aqueous starch solution is supplied to the storage tank, so the starch is sufficiently stirred and mixed. By producing a starch aqueous solution in a state and supplying the starch aqueous solution to a storage tank, it becomes possible to produce a starch solution having a uniform concentration.

  Based on the measurement result of the weight measuring means, not only the supply amount of starch supplied to the storage tank but also the supply amount of water supplied to the storage tank is managed. A dedicated weight measuring means, a flow meter and the like are not required, and the configuration can be simplified. Moreover, as in the case of starch, it is possible to supply water in small portions, and it is possible to accurately manage the amount of water supplied using a small weight measuring means with little measurement error.

  The fifth characteristic configuration of the present invention is configured such that, in addition to the first characteristic configuration to the fourth characteristic configuration, the heating means performs a heating action by injecting high-temperature steam into the storage tank. In the point.

  According to the fifth characteristic configuration, since the coating material solution is heated by injecting high-temperature steam, the temperature of the coating material solution is increased by heating with a high temperature heating means such as an electric heater. However, when heated using high-temperature steam, the coating solution does not heat up to a temperature that greatly exceeds about 100 ° C., and the coating solution is cured. The coating solution can be produced in a good state without any disadvantages such as scorching or burning.

  Also, since the high temperature steam is injected into the storage tank, it is possible to exert the function of stirring the high temperature coating material solution stored in the storage tank by the jet power of the injected steam. It becomes easy to maintain a high temperature coating material solution in a substantially uniform high temperature state with little temperature unevenness.
