度は劣化する。However, in the above-mentioned prior art, since a granular material having high adhesiveness such as a detergent composition adheres to the probe, the accuracy of detection of the collision pressure of the granular material by the probe decreases, The granulation state cannot be detected accurately. Also, when granulating a granular material having a high stickiness component, the particle size of the granular material in the granulating process increases rapidly, while the collision pressure is converted into an electric signal and subjected to fast Fourier transform. Since it takes time to obtain the vibration strength corresponding to the particle size of the granular material, there is a delay in the granulation state detection, especially in the granulation process where the particle size changes greatly, and the particle size detection accuracy deteriorates. .

The relationship between the resistance value corresponding to the resistance and the granulation state corresponding to the progress of granulation is obtained in advance, and the power required to rotationally drive the member rotating in the flow region of the granular material in the granulator is used. It is characterized in that a corresponding value is measured as the resistance value and the granulation state is detected from the measured resistance value and the previously obtained relation. Since the stirring resistance of the granules changes with the progress of granulation, the correlation between the resistance value corresponding to the stirring resistance and the granulation state corresponding to the progress of granulation is obtained in advance, and the resistance value is By measuring during granulation, the granulated state can be obtained from the relationship and the measured value. On this occasion,
Since it is difficult for the granular material to adhere to the member that rotates in the flow region of the granular material, the granulation state can be determined by measuring the resistance value that corresponds to the power required to drive the rotating member to rotate. Can be accurately detected. The resistance value may be a value corresponding to the power required to rotationally drive the rotating member, for example, the power consumption value corresponding to the load of the prime mover that rotationally drives the rotating member, the load current value, The bending and vibration strength of the rotating member can be measured as a resistance value. The granulation state may be one that can represent the progress of granulation in correlation with stirring resistance, for example, the average particle size of the granules to be granulated, the bulk density, and the total granules. Yield, which is the weight ratio of the powder or granules that pass through the sieve with a certain opening, Coarse powder ratio, which is the weight ratio of particles having a size equal to or larger than the set particle size to the weight of the whole powder, or less than the set particle size to the weight of the whole powder The fine powder ratio, which is the weight ratio of the particles, may be detected.

確保できる。The above-mentioned granulator comprises a container for containing the powder and granules, a rotary shaft provided in the container so as to be rotatable about the vertical axis, and a stirring blade provided so as to rotate together with the rotary shaft. The stirring blade is disposed on the inner bottom surface of the container with a clearance, and the relationship between the clearance and the resistance value and the granulation state is obtained in advance, and the stirring blade is rotationally driven as the resistance value. measuring the value corresponding to the load, so that the resistance value and the granulation condition are correlated, to set based on the relationship determined the clearance. The present inventor, when stirring the powder or granular material in the container by the stirring blade that is rotationally driven about the vertical axis, if the clearance between the stirring blade and the bottom surface inside the container is not sufficiently secured, the stirring blade The shearing force acting on the granular material between the bottom surface inside the container becomes excessive, and the collapsing granular material adheres to the stirring blade and the bottom surface inside the container, resulting in a load on the prime mover that rotates and drives the stirring blade. It was found that the corresponding resistance value and the granulation state became uncorrelated. Therefore, the clearance is set based on the previously determined relationship between the resistance value and the granulated state so that the resistance value and the granulated state are correlated. Thereby, the detection accuracy of the resistance value can be secured.

にならないように設定するのが好ましい。The relationship between the clearance between the stirring blade 108 and the inner bottom surface of the container 103, the resistance value, and the granulation state is obtained in advance, and the resistance value and the granulation state are correlated with each other. In addition, the clearance is set based on the obtained relationship. That is, unless the clearance is sufficiently secured, the stirring blade 108 and the container 103
The shearing force acting on the granular material between the inner surface and the inner bottom surface becomes excessive, and the collapsed granular material adheres to the stirring blade 108 and the inner bottom surface of the container 103, and as a result, the stirring blade 108 is rotationally driven. The resistance value corresponding to the power consumption value of the first prime mover 171 does not correlate with the granulated state corresponding to the average particle size of the granulated product. Therefore, the clearance is set so as not to become too small based on the previously determined relationship between the resistance value and the granulated state so that the resistance value and the granulated state are correlated. Further, if the clearance becomes too large, the shearing force acting on the powdery particles between the stirring blade 108 and the inner bottom surface of the container 103 becomes weak, which hinders the progress of granulation or the powder stays. Therefore, the clearance is preferably set so as not to become excessive in the range where the resistance value and the granulated state correlate.

る。12 (1), 13 (1) and 14
From (1), the average particle size corresponding to the granulation state increases as the granulation time elapses, and the granulation proceeds, and the progress degree increases as the clearance decreases. This is because as the clearance becomes smaller, the shearing force acting on the granular material between the stirring blade 108 and the inner bottom surface of the container 103 increases. From (2) and (3) of FIG. 12,
When the breaking load corresponding to the adhesiveness of the granules is 47 gf, the power consumption value corresponding to the stirring resistance increases with the lapse of granulation time, regardless of whether the clearance is 2 mm, 4 mm, or 7 mm. The power consumption increases as the clearance decreases, and the granulation state correlates with the resistance value. From (2) and (3) of FIG. 13, when the breaking load corresponding to the adhesiveness of the powder or granular material is 60 gf, the clearance is 4
If it is mm or 7 mm, the power consumption value corresponding to the stirring resistance increases as the granulation time elapses, and the power consumption increases as the clearance becomes smaller, and the granulation state and the resistance value correlate. However, when the clearance is 2 mm, the change in the power consumption value with the passage of the granulation time is not constant, and the granulation state and the resistance value are not correlated. 14
From (2) and (3), when the breaking load corresponding to the adhesiveness of the powder and granules is 97 gf and the clearance is 7 mm, the power consumption value corresponding to the stirring resistance according to the progress of granulation time. However, when the clearance is 2 mm or 4 mm, the change in the power consumption value with the passage of the granulation time is not constant, and the granulation state and the resistance value correlate. Will not do. FIG. 16 shows the relationship between the lower limit value of the clearance set so that the granulated state and the resistance value are correlated with each other, and the breaking load corresponding to the adhesiveness of the powder or granular material. By setting the clearance above the lower limit value, it is possible to accurately detect the granulation state based on the measured value of the resistance value without being affected by the adhesiveness of the powder or granular material.
For example, when granulating a sticky detergent composition having a breaking load of 60 gf, a water content of 5% and a powder temperature of 40 ° C., the clearance is preferably set to 4 to 7 mm. In applying the present invention, the breaking load corresponding to the adhesiveness of the powder or granular material is preferably 30 gf or more, and more preferably 4
It is 5 gf or more, more preferably 50 gf or more.
