Abstract

PURPOSE:To enable an experimenter to obtain information in necessary form while conductive expansion tests simultaneously and automatically by recording the expansion quantities of individual samples automatically as functions of time. CONSTITUTION:A sample 2 put in a sample container 1 is sunk in a thermostatic water tank 3 which is brought under temperature control into a constant environment. Then variation in the height of the peak surface by the expansion of the volume of the sample 2 is converted into the up-down motion of a drop lid 4 and the motion is transmitted to the pulley 8 of a potentiometer 9 by a coupling device 6 to rotate the pulley. A meter which has a common rotary shaft to the pulley 8 converts the variation of the sample into variation of an electric signal, which is converted into a numeric signal that an input/output circuit requires, so that the signal is stored in an information processor.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is mainly used for testing the rising power of bread dough, and it can obtain a large amount of information such as the fermentation power of bread yeast and the shape retention power of dough from the volume change of the sample. This relates to production with the purpose of obtaining it fully automatically.

[Purpose of the invention]

It is an object of the present invention to provide a device aimed at saving labor and eliminating individual differences among experimenters in the dough swelling force test using a cylinder, which has been carried out in the United States since the invention.

[Conventional technology]

Conventionally, the cylinder test according to the Japan Yeast Industry Association method has been widely used as a bread dough evaluation test method in the bread industry.This is a test method in which a certain amount of bread dough is placed in a cylinder, maintained at a constant temperature, and the degree of expansion is measured. A person reads the height of the dough using a scale attached to the cylinder at regular intervals and records it. Then, the height value is calculated, and the change in volume of the sample is determined and organized as a function of time.

[Problem to be solved by the invention]

This operation is generally carried out in a constant temperature room, and the temperature and humidity are around 60C and 290%RH, which is a bad environment. This experiment does not have a means to automatically record the expansion force as a function of time, so the experiment This requires a person to observe and record data over time, which results in great trouble and expense.

Traditionally, bread dough rises #! During the process, the peak is usually carved into a convex hemispherical shape. Therefore, if the entire height of the top is measured, an accurate volume cannot be determined due to individual differences in spherical curvature. In addition, due to gas bubbles generated during the fermentation process, the shape of the top often becomes irregular and uneven.
This was a cause of measurement error. So the same '-i8. Experiment f: When performed at different times and locations, these results did not match and were not repeatable, but this was clearly due to the laboratory treatment lp!
This is due to f-characteristics and reading errors of individual experimenters.

Furthermore, the final experimental results are evaluated by manually creating tables and graphs, but they often vary due to errors in reading caused by human means and differences in calculation methods. Examination is often difficult and rare.

[Means to completely solve problem a]

The present invention provides a test sample that automatically records the expansion of the sample as a function of time.
This is an attempt to solve the above problem.

Furthermore, this test device can handle a large number of samples at the same time by combining individual sample measuring devices. This device has an expansion conversion mechanism that continuously records the amount of dough expansion over a certain period of time, automating the work that traditionally required experimenters to measure and record the amount of expansion over time.

Therefore, the burden on the experimenter under adverse environments can be reduced, and measurement errors due to individual differences among experimenters can be almost completely eliminated. Previously, when performing experiments under different conditions, it was necessary to change the entire environment of the laboratory itself, and it was impossible to conduct these experiments in parallel at the same time. Therefore, this device has a constant temperature water tank that keeps the sample under constant conditions without receiving 1# sauce from external conditions, and the sample container is submerged in the water tank using the 0 conventional method. Although it is difficult to conduct experiments because it would be difficult to read the scale on the cylinder enclosed in the container, according to the present invention, it is possible to control the environment in the room. It is possible to conduct experiments under any temperature conditions desired by the individual.

The results obtained with this apparatus are identical to those obtained in the nine-cylinder dough expansion force test used for this purpose, and are completely consistent and repeatable.

The present invention also provides a measurement device that holds a plurality of different dough samples at one time in a controlled temperature environment and continuously records the overrise caused by fermentation. Father, the results obtained from experiments are recorded using an information processing device, so
The information required by the experimenter can be obtained instantly and easily without modifying the main body of the apparatus.

The device of the present invention has a potentiometer directly connected to a drop-lid in the measurement container, which converts and outputs an electrical signal in response to a change in volume of the sample in the measurement container. In this device, the shape of the drop lid is flat, so that volume measurement errors due to irregularities in shape do not occur.

Furthermore, since the signal from the potentiometer can be recorded continuously, information on a plurality of samples can be measured simultaneously at any arbitrary time. The output signal is converted into a digital signal by an electronic circuit, processed by an information processing device such as a microcomputer, and various data can be obtained. In this device, the amount of height change that has occurred in the bread dough is input as expansion amount information to the information processing device that is attached to it as a numerical signal, and a large number of information processes can be performed instantly and automatically. Labor-saving and economically superior Minato f for experiments
I will provide a.

Furthermore, the results obtained by this device are exactly the same and compatible with the results obtained by the conventional cylinder method, and can be used for comparison with the information that has been accumulated up to now.

〔Example〕

As shown in FIG. 1, in the unexploded l311'+ example, the sample 2t placed in the sample container 1 is submerged in a constant temperature water bath 6 whose temperature is controlled to maintain a constant environment, and the top surface due to the volume expansion of the sample is submerged. The height change is made by changing the top and bottom of the drop lid 4, and the pulley 8t of the nine potentiometers 9 connected thereto is rotated. Here, the potentiometer 9, which has a rotation axis common to the goo 98, converts changes in the sample into changes in electrical signals, which are converted into digital signals by the input/output circuit 10 shown in FIG. It is transmitted as information.

The sample container 1 is a cylindrical tube made of glass or resin, and has a closing mechanism 16 at the bottom. It is desirable that this closing mechanism be removable to facilitate loading and unloading of samples and cleaning of the container.

If a cylinder for the Yeast Industry Association is used as the sample container 1,
It is very convenient because it can save labor and improve accuracy of the conventional manual inflation force test. The upper part of this sample container 1 forms an opening because the connecting part 6 that transmits the movement of the drop lid 4 to the goo 98 passes through it, but it is necessary to take into consideration the case of other experiments in which gas generated during fermentation is collected and analyzed. This portion may also be equipped with a sealing mechanism, and a lid may be used that has a small hole for taking out the gas, and the gas may be led out through the small hole.

Conventionally, in this type of experiment, it was necessary to cover the sample with a petri dish or the like to protect the surface of the sample from drying out. However, in the actual production, there is no need for this because the top surface of the sample 2 is tightly covered with the drop lid 4.

During the experiment, the sample container 1 is submerged in a constant temperature water bath 6, and the temperature of the sample is kept constant. The vertical movement of the drop lid 4 is transmitted to the data 8 by the coupling device 6 and rotates the potentiometer 9.

The potentiometer 9 outputs an electrical signal corresponding to the rotation angle, and upon receiving the signal, the input/output circuit 10 converts it into a necessary numerical signal and records it in the information processing device 11 (see FIG. 6). Here, a non-slip belt such as a timing belt is used for the delay introduction b: t6 and the data 8 so as not to cause an error due to slipping, etc., and a belt with a non-slip belt such as a timing belt is used for the delay introduction b: t6. A 14t weight is attached to the end.

Also, by replacing the potentiometer with a linear type potentiometer as shown in FIG. 2, pulleys and the like can be omitted and the system can be used in a dark manner, but in this case there is a drawback that the device becomes a little slow.

In this apparatus, a lift handle 7C is provided to facilitate attachment and detachment of the sample container 1 when taking it in and out at any time. This handle 7
Lid 4, sample container holter 5° connection part 6% daily 8
, the potentiometer 9, etc. are integrated, which makes the mechanism very simple, and the 1M degree and maintainability are very good.

Information for the next experiment input into the information processing device 11 such as a computer is recorded over time according to the software.

At the same time, the necessary calculations are made and organized and displayed in the form of charts, etc. In addition, it is also possible to take factors such as the laboratory environment and actual conditions into account at this time, making it possible to save labor on all of these tasks that were conventionally performed manually. The information obtained in this way will be memorized! Needless to say, since all data is recorded in the same location, it is extremely easy to search, compare, and examine individual data.

In FIG. 6, a large number of VC devices shown in FIG. 1 are all arranged in parallel and housed in a housing 15, thereby making it possible to experiment with a plurality of samples at once. Reference numerals are the same as in FIG. 1, detailed explanations are omitted, and differences from FIG. 1 will be explained.

Reference numeral 12 designates a housing part for the air circuit, which is used for temperature control 1' of the constant temperature water tank 6. Handle 7 is inserted through the outside of the housing 15 through slots drilled in each panel, and is gripped to the top end. +7t- movement so that only the sample container 1 can be taken out through the window 16 between the panel and the water tank 6, improving operability.

〔effect〕

According to the present invention, expansion tests for different bread doughs, which conventionally had to be done manually, can be carried out simultaneously and automatically in all multiple areas, and the information obtained can be obtained in the form required by the experimenter.

In general, with the cylinder method known so far, this information can only be collected by making numerous observations of individual fabrics at very short time intervals, and generally by the person witnessing the test. It should be noted that this was completely inaccurate even though it required . Furthermore, in contrast to the normal procedure for fermentation experiments in this building, which takes a considerable amount of time, the two devices operate automatically and do not require any human attention, which actually improves the reliability of the tests. You should be careful what you are giving away.

It goes without saying that this device has a completely simple structure and is trouble-free and easy to maintain.
