Description

Detailed Description of the Invention 3. Detailed Description of the Invention Industrial Field of Application The present invention is capable of drying for a desired drying time preset before the start of drying without causing shell cracking or insufficient drying. Concerning possible grain drying methods.

BACKGROUND OF THE INVENTION Conventionally, a grain dryer equipped with an automatic drying function is known, for example, as described in Japanese Patent Application Laid-open No. 150475/1983. As shown in Figure 2, the grain drying method adopted in this grain dryer is to artificially measure the initial moisture content of the grain to be dried before drying begins, and calculate the amount of grain loaded and the finished drying moisture content. The drying time is also artificially set, the time required for drying is calculated, and the drying work is performed.

Problems to be Solved by the Invention Incidentally, in the conventional grain drying method described above, drying is controlled based on the moisture content of the grain, the amount of grain put in, etc. There are many cases where I can't find customers. For this reason, the drying work may interrupt the next day's work hours, causing problems in the work. Also,
If the scheduled drying finish time falls late at night or early in the morning, it is extremely inconvenient for the work.

Therefore, in automatic drying of grains, there is a need to eliminate such inconveniences.

Means for Solving the Problems The present invention solves the above-mentioned problems, and the details thereof will be explained below using FIG. 1 corresponding to an embodiment. When drying grains, set the desired drying time before starting drying. Next, the initial moisture content of the grain is measured, and the specified drying moisture content is set (generally, in drying facilities, etc., it is set to a constant value depending on the grain type and region). Then, from the drying capacity of the dryer, the weight of the grain that can be dried to finish moisture is calculated after the set drying time has elapsed, and that weight of grain is loaded into the dryer to start the drying operation.

Function As described above, at the start of drying, the weight of grain that will be dried to finish moisture in the desired drying time is loaded, so the drying work can be completed at a time convenient for the work.

Example An embodiment of the present invention will be described with reference to FIG.

To start the drying work, first, the desired drying time is set based on the desired drying finish scheduled time or drying start time. Next, the initial moisture content of the grain to be dried is automatically measured, and the specified value for the finished drying moisture content is set. Then, the weight of grain that can be dried in the desired drying time is calculated from the above drying time, the measurement data of the initial moisture content of the grain, the set instruction value of the finished moisture content of the grain, and the drying capacity of the dryer, and the weight of the grain that can be dried in the desired drying time is calculated. If grain is loaded and automatic drying is started, automatic drying will end when the desired drying time has elapsed. In other words, at drying facilities etc.
In addition to automatically measuring the initial moisture content, this data is further memorized and calculated using the drying finish moisture indication value and drying capacity to calculate the dryable grain weight and finally determine the total amount of grain loaded. Become.

By the way, drying grains means removing moisture contained in the grains. The ability to remove moisture is approximately determined by the amount of heat applied to the grain by the hot air generator. Therefore, 1
The water removal capacity per hour is almost determined by the amount of heat supplied per hour.

The amount of water that must be removed to complete drying is calculated using the following formula:

Amount of water removed for drying (g) 9) Also, the time required for drying is becomes.

Therefore, if the drying time is determined, and the moisture content at the time of drying and the desired finishing moisture are known, the weight of the grain that can be dried in the set drying time is determined by the following equation.

Initial Moisture - Finished Moisture Now, it is assumed that 2 out of 10 moisture can be removed by evaporation of kerosene I K9 at an air temperature of 258 C to 30 C, and the combustion capacity of the burner is 5 out of 10 per hour (100 Kp).
), and if the initial moisture to be dried is 25%, the finished moisture is 15%, and the desired drying time is t - 20 hours, the loaded weight of grain (29) is calculated as follows: be done.

(25 arrogance - 15 chi) According to the method of the embodiment described above, the drying work can be completed when the drying time set according to the work schedule etc. has elapsed, so that the drying work progresses smoothly. Moreover, it works conveniently and efficiently.

I can do it.

Effects of the Invention In short, the present invention has the above-mentioned technical means and works, so it is possible to finish the drying work in the desired drying time before the start of drying, and there is no problem of shell cracking or insufficient drying. To achieve the effect that drying work can always be carried out smoothly, efficiently, and conveniently without causing any problems.

Claims (1)

[Claims] Before starting drying, set the desired drying time, and calculate the weight of grain that can be dried in the drying time set above based on the initial moisture content of the grain to be dried, the set value of the finished drying moisture content, and the drying capacity of the dryer. This grain drying method is characterized in that the weight of grain is calculated, loaded into a dryer, and automatically dried.
