Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a grain drying method that allows grain to be dried by a desired time preset before the start of drying without causing cracking or insufficient drying.

BACKGROUND OF THE INVENTION Conventionally, grain dryers equipped with an automatic drying function, as described in Japanese Patent Application Laid-open No. 55-150475,
widely (known and used;

Problems to be Solved by the Invention Incidentally, in the above-mentioned conventional grain dryer, drying is controlled by drying control factors such as grain moisture and temperature, so the required drying time is different from the drying time desired by the operator. There are many cases where I can't find customers. For this reason, the time required for drying may interrupt the next day's work hours, causing a hindrance to the work. Furthermore, if the scheduled finishing time of the ceremony is late at night or early in the morning, it is very inconvenient for the work.

Therefore, in view of the drawbacks of the conventional method, the present invention has been developed to prevent shell cracking and insufficient drying even if a desired drying finish time is set in advance before the start of drying and a possible drying speed is selected. It is an object of the present invention to provide a grain drying method that can finish drying by a set scheduled drying finish time without any delay.

Means for Solving the Problems The present invention has the following five technical means for achieving the object. In other words, in the grain drying method according to the present invention, a desired drying finish scheduled time is set before drying starts, and the drying time from the current time to the above-set drying scheduled time and the initial stage of the grain are set. This method is characterized in that a possible drying speed is calculated from the moisture content, finished drying moisture content, etc., and a drying start time is set based on the required drying time determined by the selection of the drying rate, and automatic drying is performed.

A predetermined amount of grain to be dried is loaded into the grain dryer,
When the drying operation is performed by the means according to the present invention, the grain is dried to a predetermined finishing moisture level at a desired finishing drying time set in advance, and the drying operation is completed.

For the scheduled drying finish time, only the time is set if the drying starts on the same day, and the date and time is set if the drying starts on the next day.

Embodiment An embodiment of the grain drying method according to the present invention will be described with reference to the drawings.

Pour the specified amount of grain to be dried into the grain dryer,
To start the drying process, follow the steps below.

First, the worker can choose a convenient time (
date and time) as the scheduled drying finish time (5). The current time is constantly measured by a clock device. Then, the available drying time (C) that can be spent on drying is calculated from the scheduled drying finish time and the current time (03). In addition, by measuring the initial moisture content of the grain to be dried (0) and setting the drying finish moisture content of the grain, the possible drying rate can be calculated from the moisture content that needs to be dried and the drying time (Q). Possible drying speeds [F] are displayed only within the range in which grains do not crack or become insufficiently dried.

Therefore, if the operator selects the desired drying speed (Q),
The time required for drying, that is, the required drying time 0, is calculated, so calculate the time corresponding to the time calculated backward by the required drying time 0 from the scheduled drying finish time, and use this as the drying start time (I). Make settings (reservations).

If the grain dryer is automatically operated according to the set control conditions, the grain will be finished drying by the desired time.

The possible drying speed [F] is displayed in steps of, for example, 0.1% based on the drying loss rate (moisture loss rate per hour), and one of them is selected when selecting the drying speed. It would be even more convenient if you could do it by doing this.

Effects of the Invention Since the present invention has the above-mentioned technical means and works, it is possible to set a desired drying completion time in advance before starting drying and select any possible drying speed. ,
It is possible to finish the drying by the set scheduled drying time without causing shell cracking or insufficient drying.

[Brief explanation of drawings]

The drawing is an explanatory view showing one embodiment of the grain drying method according to the present invention.

Claims (2)

[Claims] (1) Set the desired drying finish scheduled time before starting drying, and determine the drying possible based on the drying time from the current time to the drying finish scheduled time set above, the initial moisture of the grain, the drying finish moisture, etc. A grain drying method characterized by automatically drying by calculating a drying speed and setting a drying start time based on the required drying time determined by the selection of the drying speed. (2) A grain drying method according to claim 1, characterized in that possible drying speeds are calculated in multiple stages according to the drying loss rate, and the drying speed is selected for each stage. .
