This can be seen in the Specification No. 9. The former measures the weight of the sample on the conveyor to control the transport speed of the conveyor to keep the amount of discharge from the conveyor constant, while the latter measures the weight of the sample on the conveyor and controls the attenuation of microwaves by the sample. The purpose is to measure and determine the moisture content of a sample.

測定装置を提供することを目的とする。In the above-mentioned apparatus, if the sample has high moisture content or is flaky, the sample tends to adhere to the conveyor and cause measurement errors. Therefore, an object of the present application is to provide a measuring device for a small piece aggregate sample, which improves measurement accuracy by preventing the sample from adhering to a conveyor.

を変形させれば剥離しやすくなる。When a small piece aggregate sample adheres to a conveyor, moisture between the sample and the conveyor may act as an adhesive. In this case, if the contact area between the conveyor and the sample is heated, this water becomes a gas, increases in volume, and diffuses into the air, weakening the adhesive force and making the sample easier to peel off. Furthermore, if the sample is deformed by the heating, it becomes easier to peel off adhesion caused by static electricity or other causes.

The transmitting antenna 9 is connected to an oscillator 11, and the receiving antenna 10 is connected to a receiver 12. A load cell 13 detects the weight of the conveyor 1 as a whole. Reference numeral 14 denotes a far-infrared heater, which is disposed at a position that faces the conveying surface 2' of the trough from below and does not easily affect the propagation of microwaves.

Microwave oscillator 11. The far infrared heater 14 is activated. Then, the microwave propagates between the transmitting and receiving antennas 9 and 10, the trough 2 vibrates as shown by the two-dot chain line and arrow in FIG. 1, and the conveying surface 2' of the trough is heated to 50 degrees or more. Furthermore, the control unit 15 controls the geophone 12 at that time,
The detection data of the load cells 13 are averaged and the initial value MOLWO of microwave energy and conveyor weight is stored.

Examples of the sample include tea leaves in the process of producing crude tea, fresh leaves of various plants, gravel, and the like. Then, while the sample is being conveyed by the conveyor 1, the controller 15
For example, the detection data of the geophone 12 and the load cell 13 are accumulated for one minute at an interval of 50 pieces/second, and the average thereof is set as the detection values Ml and Wl. Microwave energy detection value Ml
is a value smaller than the initial value MO because the microwave is attenuated by the sample, while the detected value Wl of the conveyor weight is larger than the initial value WO due to the weight of the sample.

が減るため、測定精度が向上する。However, in this device, the contact area between the trough and the sample is heated by the far-infrared heater 14, so the moisture present in the contact area is heated and turns into a gas, which increases the volume and reduces the adhesive force when it diffuses. The weakened sample becomes easier to separate from the trough. In addition, even if the sample adheres due to static electricity or other factors, if the sample is deformed by heating, it becomes easy to peel off. If part of the sample were to adhere to the trough 2 after the initial value MOLWO was determined as described above, the weight or water content of this sample would affect the detected values Ml and Wl, causing measurement errors. I end up. Furthermore, if the -degree sample adheres, it will act as resistance, inhibiting the transport of the sample, and may cause other samples to adhere, making measurement completely impossible. However, according to the apparatus of this embodiment, the possibility of the sample adhering to the trough is reduced, so the measurement accuracy is improved.

じにくいため測定精度を向上できる。Note that heating the sample more than necessary may change the moisture content and components of the sample, so it is best to avoid heating any area other than the contact area between the sample and the conveyor. For this reason, in this embodiment, the far-infrared heater 14 is arranged below the trough 2. In addition, in this example, since a so-called vibrating conveyor is used as the conveyor, the density of the high-moisture particle aggregate sample being transported tends to be uniform, and since the sample is less likely to adhere, measurement accuracy can be improved.

必要がある。A trough 17 is a substitute for the trough 2 in the above embodiment, and a nichrome wire 2 is inserted between the inner trough 18 and the outer trough 19.
There are 0's all over the place. When a voltage is applied to this, the nichrome wire 20 generates heat and heats the contact surface of the sample on the trough 17. If such a trough 17 is used, almost no installation space is required for the heating means, so the apparatus can be made compact. However, in order to measure the electrical characteristics of a sample using this device, it is necessary to arrange the nichrome wires carefully.

In this embodiment, the conveying surface of the trough is made breathable and hot air is blown toward the sample to heat the contact area between the trough and the sample. The trough 21 is also a substitute for the trough 2 in the embodiment described above, and a number of ventilation holes 22 are bored in the bottom of the trough, and a ventilation chamber 23 is installed below the trough. A hot air supply pipe 24 made of a flexible material is provided in the ventilation chamber 23.
The hot air supplied from the pipe 24 into the ventilation chamber 23 is vented upward through the ventilation hole 22. If such a trough 21 is used, the sample will be more difficult to adhere to. Furthermore, by selecting the material of the trough 21, it is possible to measure the electrical properties of the sample.
