[Problems to be solved by the invention]

The described rheology measuring apparatus is a measuring apparatus mainly for measuring the viscosity of a sample and not being able to measure the fluidity of the sample very clearly, and a measuring apparatus for a liquid which does not originally contain solid matter. If the ingredients are mixed in the sample like curry, the rheology cannot be measured, and the solids of the ingredients will hit the rotating blades, and the accurate torque will not be detected.

[0016]

The operation of the rheology measuring device having the above configuration will be described below. The rheological constants measured by the present rheology measuring method and apparatus are as follows: the size (length, cross-sectional shape and dimensions) of the flowing part through which the sample flows, the inclination angle of the flowing part (horizontal 90 to 160 degree inclination angle), Conditional rheological constants measured under conditions such as part type, sample temperature, sample volume, and the structure and performance of the sample delivery device.

The fluidity of the rheological constant indicates the degree of ease of flow of the sample, and the sample delivery means 2 pumps the sample in the production tank 15 or the transfer pipe 19 through the sample pipe 2b to a pump 2a (a fixed pump). And a predetermined amount of sample is tilted from the point when the outlet 2d of the solenoid valve 2c linked to the pump 2a provided at the tip of the sample pipe 2b is opened or the point when the outlet 2d of the solenoid valve 2c is closed. The computer 14 measures the time elapsed until the sensor part 7 of the sample detecting means 6 detects the sample flowing out of the angled flow part 3 and flowing out of the flow part 3 and flowing out of the outlet 3 b for the first time by the sensor part 7 of the sample detection means 6. The intermediate elapsed time is defined as the flow elapsed time (second), and it is evaluated that the shorter the elapsed flow time, the better the flowability, and the longer the elapsed flow time, the poor the flowability.

Next, the viscosity of the rheological constant indicates the degree of viscosity of the sample, and the sample flows from the flowing part 3d when the outlet 2d of the sample sending means 2 is opened or when the outlet 2d is closed.
The computer 14 measures the integrated elapsed time until the sensor section 7 of the sample detecting means 6 detects the sample that has flowed through the outlet 3b and finally flowed out from the outlet 3b. Assume that the viscosity is high if the elapsed time of the end of the outflow is long, and low if the elapsed time of the end of the outflow is short.

Next, the sharpness of the rheological constant indicates the sharpness of the sample such that the sample droops, and the sample is removed from the point when the outlet 2d of the sample sending means 2 is opened or the point when the outlet 2d is closed. The state in which the fluid flows through the fluidizing section 3 and flows out from the outlet 3b initially flows out in a continuous and continuous state, but flows out in the middle of the outflow in an intermittent state in which it is interrupted, and changes from this outflow start point to an intermittent outflow. The outflow of the sample up to the point in time is detected by the sensor unit 7 of the sample detection means 6,
This section elapsed time is measured by the computer 14 to be a continuous outflow section elapsed time (seconds), and the outflow of the sample from the time when it changes to intermittent outflow to the time when the outflow ends is detected by the sensor unit 7 of the sample detecting means 6, This section elapsed time is measured by the computer 14 and taken as an intermittent outflow section elapsed time (second).
Samples that show remarkable thixotropy flow intermittently from the outflow start time, so the intermittent outflow section elapsed time from the outflow start time to the outflow end time is measured by the computer 14, and the sharpness of the sample is continuously evaluated depending on the purpose. The evaluation is based on the elapsed time of the outflow section and the evaluation of the elapsed time of the intermittent outflow section.In general, both evaluations are performed. Evaluate the badness.

Next, the thixotropic property of the rheological constant is indicated by the degree of the intermittent state in which the outflow of the sample is interrupted. For example, tomato ketchup is difficult to flow when left standing for a long time, but it becomes easier to flow when vigorously stirred. This property is called thixotropic, and this property appears by forming a bonding structure by the cohesive force between particles, is strongly governed by the properties of the particle surface, and the sample in which the thixotropic phenomenon appears remarkably due to structural destruction is The sample flows out in an intermittent state in which the sample flows out, and the section of the sample flowing out from the start point to the end point of the outflow is detected by the sensor unit 7 of the sample detecting means 6. Measured, the elapsed time of the section where the outflow started was interrupted (seconds), the elapsed time of the section where the outflow was interrupted (seconds), and the end of the outflow And when interruption interval elapsed time (in seconds), the most important is these flow start time interval elapsed time interrupted, interrupted interval elapsed time is long enough thixotropy large, evaluates short enough thixotropy is small.

Next, the method of use of the present invention will be described with reference to FIG.

On the other hand, it flows out from the outlet 3b and
Is received by the receiving portion 8a of the sample receiving portion 8 and flows out of the outflow portion 8b to the production tank 15 or the transfer pipe 19, or is received by the receiving container 8c shown in FIGS.

Next, the elapsed time during which the outflow of the sample from the outflow port 3b is interrupted (light receiving time) is determined by the detection end set time initially set in the operation 71 (the required set time is 30 seconds depending on the type of the sample and the inclination angle of the flow part). For example, when the set time exceeds 60 seconds (set between 15 minutes and 15 minutes), the computer 14 determines whether the measurement of the operation 76 is completed, and ends the measurement.

Next, in operation 77, the measurement data collected by the data collection device 13 in operation 75 is input to the personal computer 14, and the signal light emitted from the light emitters 7a and 7b is received by the light receiver 7.
The rheological constant is calculated by the personal computer 14 based on the elapsed time (seconds) that the light enters c and 7d and the elapsed time (seconds) when the signal light is blocked by the outflow of the sample.

As another operation of the operation 78,

The sensor section 7 of the sample detecting means 6 can be measured, and the sensor section 7 of the sample detecting section 6 is provided at two upper and lower positions between the outlet 3b and the sample receiving section 8 as shown in FIGS. The outflow speed (mm / sec) can be measured. The higher the outflow speed (mm / sec), the better the flowability (larger), and the lower the outflow speed (mm / sec), the greater the viscosity (sticky). And outflow velocity (m
m / sec), a flow curve of the sample can be created as shown in FIG.

It is also possible to input the known data into the personal computer 14 and express the properties of the sample by an evaluation index, the converted viscosity, and the dischargeability and filling property by the evaluation index.
Further, the mixing ratio of a plurality of raw materials is determined from the measured rheological constants, the concentration of the sample is estimated, and the amount of water is estimated.
Is printed by a printer (not shown).

Next, as a cleaning work of the post-measurement work 81,
The work of removing the fluid member 3c from the fluid part supporter 4 and the work of removing the sample received in the receiving container 8c are performed, and the fluid part 3 moved by the fluid part moving means 24 shown in FIGS.
