Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention periodically samples the grain in a grain dryer, measures the moisture value from the sample grain, and controls the operation of the grain dryer based on the measurement result. The present invention relates to a moisture information display device used in a system and connected to an automatic moisture meter that measures a moisture value of a sample grain.

[0002]

2. Description of the Related Art In a grain dryer, in order to perform proper drying according to the type, property, and property of the grain to be dried, the grain drier is dried while periodically detecting the moisture state of the grain. The operating status of the burner device and the grain circulation device in the machine is automatically controlled. At this time, in order to detect the moisture state of the dried grain, an automatic moisture meter that measures the moisture value of the sample grain by periodically sampling an appropriate number of grains in the grain dryer is used. The measured moisture value data is statistically processed and used as detection data in automatic control of the grain dryer.

Here, it is generally practiced to obtain a simple average value from the moisture value data measured by an automatic moisture meter and detect the moisture state of the dried grain by this average value. The grains often contain high-moisture grains called immature rice, and the moisture distribution state of the grains may vary widely even during the drying process. It is not possible to accurately grasp the water content of dried grains. Therefore, the statistical processing for obtaining the degree of variation of the water distribution from the measured water value data is performed, and the simple average value is corrected from the result of the statistical processing to be the detection data in the automatic control of the grain dryer, or The result of the statistical processing is displayed to allow the operator to recognize the degree of variation in the water distribution of the dried grain and prompt the necessary countermeasures.

As a conventional technique for displaying the moisture distribution of dried grains, Japanese Patent Application Laid-Open No. 6-300446 discloses:
On the control panel of the controller of the grain dryer, letters, numbers,
A screen display that can display pictures on the screen is provided, and the variation range from the upper limit value to the lower limit value of the moisture value data measured on the screen display is displayed in a time series chart and displayed. .

[0005]

The above-mentioned prior art displays the variation range of the measured moisture value data for each sampling period during the operation of the grain dryer, and only during the operation of the dryer. Since the operator is made to sequentially recognize the variation state of the measured water content, the content once displayed is erased at the next display and cannot be confirmed later. Therefore, the changes in the moisture state of the dried grains from the start to the end of the drying process are summarized and used as reference materials for future countermeasures after the completion of drying, or the measured moisture value data is used to change the setting of the control device. When it is desired to use it as a material for, it is necessary for an operator to record the moisture information that is sequentially displayed during the drying process, and there is a problem that the moisture management work in grain drying is troublesome.

Further, since the control panel of the controller in the grain dryer and the screen display for displaying data are integrated, there is no freedom in handling and recording data, and water management work is performed. There was a difficult problem.

The present invention has been proposed in order to deal with such a problem, and facilitates the moisture management work during drying, and confirms the moisture information obtained during drying even after the drying work. It is an object of the present invention to provide a moisture information display device that enables the above.

[0008]

In order to achieve the above object, a water information display device according to the present invention periodically measures the water content of a sample grain by sampling the grain from a grain dryer. A moisture information display device connected to an automatic moisture meter for statistically processing the moisture value data, comprising a controller section for processing the data from the automatic moisture meter and a display section for displaying the processing result in the controller section. It is characterized by being provided.

Further, the controller section is characterized in that the minimum necessary data is automatically saved during the operation of the grain dryer.

Further, the controller section is characterized by having a storage means for storing the moisture value data in at least several drying steps or the statistical processing result thereof.

Further, the present invention is characterized in that the moisture information display device outputs a moisture progress graph in the drying step.

On the other hand, a moisture information display device is connected to the automatic moisture meter, and moisture value data and the result of statistical processing thereof are input to the control unit of the moisture information display device. The control unit outputs the input data to the display unit according to arbitrary settings or instructions, and displays the measured moisture value data and the result of statistical processing of them in a form in which the moisture distribution is easy to recognize. At this time, since the moisture information display device is detachably connected to the automatic moisture meter, it can be assembled and removed freely, and the degree of freedom in handling the data sent to the moisture information display device increases.

Further, the controller unit in the moisture information display device has a function of automatically storing the data sent from the automatic moisture meter. For example, the start of drying, the average moisture value at 21%, the average moisture value at 18%, The moisture management work can be facilitated by storing the minimum necessary moisture data such as at the end of drying.

Further, since the controller section has a storage means for storing the moisture value data in at least several drying steps or the statistical processing result thereof, it is possible to confirm and analyze the data after the drying operation is completed. become,
Appropriate drying conditions for the grain can be derived from the stored data.

Furthermore, since this moisture information display device outputs a moisture progress graph in the drying process, it is possible to visualize changes in the moisture distribution of the grain to be dried, and determine appropriate drying conditions during drying. , Effective for selection.
