Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for producing tea with measurement of water content, and more particularly, to measuring the water content of tea leaves being processed in a kneading and drying process in real time. The present invention relates to a method and an apparatus for producing tea with measurement of water content by microwaves, which can appropriately perform processing at the same time.

[0002]

BACKGROUND OF THE INVENTION In the processing of tea leaves in a tea factory, a step of substantially promoting the drying of the tea leaves after the steaming step is occupied in many cases. Specifically, the water content (based on the weight of the tea leaves having no moisture) is considered. ) The kneading and drying process is performed from steamed leaves of about 360% to finally obtain crude tea having a water content of about 5%.

[0003] Such a kneading and drying step includes a leafing step, a rough kneading step, a kneading step, a middle kneading step, a middle kneading step, a fine kneading step, a drying step, and the like. Understanding the moisture content of tea leaves is an important factor in the operation of tea-making equipment to obtain high-quality products.

Therefore, recently, as a device for measuring the moisture content of tea leaves, an electric resistance type moisture meter, a microwave type moisture meter, a near infrared type moisture meter, etc. have been used. There was room for improvement in the points shown.

[0005] First, an electric resistance type moisture meter measures the electric resistance of tea leaves by positioning tea leaves between electrodes. For example, this is attached to a leaf dredge or a duck plate in a fine grinding machine. Attempts have also been made to measure the moisture content of tea leaves during processing. However, since the electric resistance type moisture meter can only measure the moisture distributed on the tea leaf surface in principle, the measurement result tends to depend on the surface resistance and is inaccurate, and it is difficult to grasp the moisture of the whole tea leaf, Its performance is insufficient for use as a moisture meter for controlling a tea production line. In addition, depending on the moisture content of the tea leaves, if a voltage exceeding a certain level is applied, dielectric breakdown is caused and the measurement becomes impossible. For example, 6 V for a coarse kneading machine and 12 V for a medium kneading machine, which are different voltages even in the same tea production line. , Which complicates the measurement system and data processing.

Further, the microwave type moisture meter derives a water content from a microwave attenuation when a tea leaf is positioned between electromagnetic horns provided opposite to each other and a weight of the tea leaf. However, since a load cell or the like which is an apparatus for measuring the weight of tea leaves is indispensable, the configuration of the measurement system becomes complicated, and there is a limit to miniaturization and cost reduction.

Further, the near-infrared moisture meter can measure moisture to the inside of tea leaves slightly more than the electric resistance type moisture meter, but in principle can only measure moisture distributed on the tea leaf surface. is there. Further, since the irradiation range of the near-infrared ray is very narrow, there is a drawback that only a very small part of the sample is to be measured. Furthermore, since the near-infrared moisture meter is expensive, it is difficult to provide a near infrared moisture meter for each device constituting the tea production line, and the versatility is poor.

Accordingly, the present applicant has developed a moisture content measuring device using a microstrip line, and has already filed Japanese Patent Application No.
-212652, "Microwave Water Content Measurement Method and Apparatus and Tea Manufacturing Process Control Method Using These" has been filed for a patent application. In this apparatus, a transmission path between a microwave transmitter and a receiver is formed by a microstrip line, and tea leaves before, after or during processing by a tea-making apparatus are positioned facing the microstrip line. Then, the water content of the tea leaves is calculated from the difference in the reception level caused by the absorption of the microwave by the moisture contained in the tea leaves.

[0009] By using such a microwave moisture content measuring device, the tea leaves near the strip conductor are to be measured. Therefore, if tea leaves having a certain bulk or more are located on the strip conductor, the sampling amount will differ. Even in this case, no measurement error occurs, and furthermore, it is not necessary to measure the weight of the tea leaves. Therefore, the measurement error of the weight is not included, so that the water content can be measured with high accuracy.

When the present inventor uses the above-described microwave moisture content measuring device to measure the moisture content in the kneading and drying process, the tea leaves being processed are first sampled from the processed portion to another portion. In this case, the water content is measured at this location. Therefore, the sampling device is an indispensable member, and this is one of the factors that hinders cost reduction, and it is difficult to realize the moisture content measurement with a fine rubbing machine or the like where it is difficult to install the sampling device. Therefore, there is room for improvement in these respects.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a basic embodiment of a method and apparatus for producing tea using microwaves according to the present invention will be described. The apparatus for measuring water content by microwave of the present invention is disclosed in Japanese Patent Application No. 10-212652 filed by the present applicant as described in the background of the invention, "Method and Apparatus for Measuring Water Content by Microwave and Tea Making Using These". The method disclosed in “Process Control Method” has a basic configuration.

Hereinafter, a specific configuration of the water content measuring device 1 will be described in detail. The moisture content measuring device 1 is formed by forming a transmission path between a transmitter 2 and a receiver 3 with a microstrip line 5, and the moisture contained in the tea leaves A located near the microstrip line 5. Then, the water content of the tea leaf A is calculated from the amount of decrease in the reception level at the receiver 3 caused by the absorption of the microwave by the above.

First, the microstrip line 5 will be described. As shown in FIG. 3, a strip-shaped strip conductor 7 is located above a conductor plate 6. In order to hold it upward, a dielectric 8 is inserted as a spacer between the conductor plate 6 and the strip conductor 7.

As a material of the conductor plate 6 and the strip conductor 7, it is preferable to use a metal having high conductivity such as copper and iron, but a metal having excellent corrosion resistance such as stainless steel can also be used.

The dielectric 8 may be made of glass fiber containing silicone, fluorine resin, epoxy resin, or the like.
Although ceramics and the like are used, in the present invention, since the installation location of the microstrip line 5 is a pressing member and a pressed member provided in the tea making equipment as described later, an epoxy resin or the like having a certain degree of hardness is used. It is assumed that a glass fiber containing is used.

In the present embodiment, among the electromagnetic waves, in particular, a microwave of 4 GHz (λ ≒ 7.5 cm) is treated as an example of the 3 to 5 GHz band (λ ≒ 10 to 6 cm), and therefore, the frequency is set to this frequency. The dimensions and the like are appropriately selected so that the characteristic impedance of the microstrip line 5 matches the transmitter 2 and the receiver 3. In the present embodiment, as an example, an epoxy resin containing glass fiber having a relative dielectric constant ε _{r of} 4.7 is used as the dielectric 8, and the strip conductor 7 is used.
And the distance between the strip conductor 7 and the conductor plate 6 was 1 to 1.5 mm.

[0030] Of course, these numerical values is to change the value of the dielectric constant epsilon _r of the dielectric 8, the frequency of the microwave or the like to be used. The frequency of the electromagnetic wave used is
The microwave is not limited to the microwave of the 3 to 5 GHz band, and an appropriate high frequency can be selected as long as the frequency is absorbed by moisture.

Regarding the planar shape of the microstrip line 5, the place where the microstrip line 5 is installed is as follows.
Since it is a pressing member and a pressed member included in the tea making apparatus constituting the rubbing and drying process, it can be appropriately selected according to the shapes of the pressing member and the pressed member. In the present embodiment, the fine rubbing machine 10 is used as the tea making device, but the outline of the configuration will be described later.
It is the tea leaves A that are actually subjected to the pressing action by the pressing members. At this time, the receiving member that pairs with the pressing members and applies the pressing action to the tea leaves A is referred to as a pressed member in this specification. And

The drawing pattern of the strip conductor 7 can take various forms. First, in the embodiment shown in FIG. 4A, the microstrip line 5 formed in a rectangular shape in plan view is used. The strip conductor 7 is routed over the entire area in the longitudinal direction. FIG. 4
In the embodiment shown in (b), the strip conductor 7 is routed along each of two long sides of the microstrip line 5 formed in a rectangular shape in a plan view, and the strip conductor 7 is folded halfway. It was made. Further, in the embodiment shown in FIG. 4C, the strip conductor 7 is folded at several places, thereby extending the entire area of the microstrip line 5 formed in a rectangular shape in plan view.

The input end 7a of the strip conductor 7
The microstrip line 5 is connected to the transmitter 2 or the receiver 3 by attaching the high-frequency connectors C1 and C2 such as SMA and BNC to the output terminal 7b and using the coaxial cable 9, respectively.

Here, the measurement principle of the water content measuring apparatus 1 having the above-mentioned configuration will be described. The attenuation of the microwave transmitted from the transmitter 2 and propagating in the microstrip line 5 is represented by conductor loss and dielectric loss. And radiation loss. That is, in the measurement system shown in FIG. 4, the difference between the microwave output value transmitted from the transmitter 2 and the microwave input value to the receiver 3 is the sum of the conductor loss, the dielectric loss, and the radiation loss. The amount of attenuation. Therefore, when a microwave of a predetermined level is transmitted from the transmitter 2 in a state where the sample (tea leaf A) is not located near the microstrip line 5, the microwave of the level attenuated by the loss arrives at the receiver 3. The reception level at this time is used as a reference value.

Then, as shown in FIG.
In the microstrip line 5
When the tea leaves A are positioned facing the strip conductor 7, the tea leaves A
The leaf A is directed from the upper edge of the strip conductor 7 to the conductor plate 6
To block the electric field _Two Natural vibration of electric dipole of O
If the frequency and the microwave frequency match, this part
Causes a resonance phenomenon of molecules, absorbs microwaves, and leaves tea
The microwave is attenuated according to the water content of A. Book in this regard
The principle of water content measurement by microwave of the invention is
It differs from the measurement principle of the electric resistance type moisture meter described in
It is.

The difference between the level of the microwave transmitted from the transmitter 2 and the level of the microwave arriving at the receiver 3 when the tea leaf A as the sample is located near the microstrip line 5 is the tea leaf. A value obtained by subtracting the amount of attenuation due to the loss (reference value) from this value is the sum of the amount of absorption of the microwave by the moisture contained in A and the amount of attenuation due to the loss. The amount of absorption of the microwave by the contained moisture is M (dB).

From this value M (dB), the water content G (%) of the tea leaf A as a sample can be obtained by the following equation. G = aM + b (a and b are correction values) Note that the correction values a and b are values obtained by experiments in advance, and are obtained by using an M value obtained by measurement using the above measurement system and a weighing scale. This is determined because a correlation can be found between the weight value of the tea leaf A before and after drying and the moisture value (actually measured value) obtained from the weight value.

As in the above-described measurement principle, the water contained in the tea leaves A (the tea leaves A located in the space where the electric field is generated) located in the state of being deposited near the strip conductor 7 absorbs microwaves. However, since the tea leaves A located away from the strip conductor 7 do not block the electric field and do not absorb the microwave, they are not measured. Therefore, as long as the thickness of the tea leaves A located on the microstrip line 5 is ensured to some extent, there is no change in the measured value due to the difference in the deposition amount (thickness) of the tea leaves A.

The microstrip line 5, which is one of the constituent elements of the moisture content measuring device 1 described above, is moved to the pressing member and the pressed member provided in the tea-making equipment constituting the kneading and drying process.
