Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention enables drying by a desired time preset by the operator before starting drying, without causing shell cracking or insufficient drying. Concerning grain drying methods.

[Prior Art] Conventionally, a grain dryer equipped with an automatic drying function is already known, as described in, for example, Japanese Patent Application Laid-open No. 150475/1983.

[Problems to be solved by the invention] By the way, in the above conventional grain dryer,
Since drying is controlled by drying control factors such as grain moisture and temperature, the required drying time often conflicts with the drying time desired by the operator.As a result, the required drying time may be adjusted to the next day's work time. interrupt,
It may interfere with your work. Furthermore, if the scheduled drying finish time falls 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 sets a desired scheduled drying finish time in advance before starting the drying process, and no matter which drying speed is selected within the range of possible drying speeds, no shell cracking occurs. To provide a grain drying method capable of completing drying by a set scheduled drying finish time without causing drying or insufficient drying.

[Means for Solving the Problems] In the grain drying method according to the present invention to achieve the above object, before starting drying, an operator first sets a desired drying finish time, and then uses a clock device to set a desired drying finish time. The possible drying time from the constantly measured current time to the scheduled drying finish time is calculated, and the possible drying speed is calculated from the initial moisture of the grain and the finished drying moisture, etc., and then the calculated possible drying speed is calculated. This method is characterized in that the drying start time is set from the required drying time determined by selecting a drying speed within a range, and automatic drying is performed.

[Function] When a predetermined amount of grain to be dried is loaded into a grain dryer and drying is started by the means according to the present invention, the grain reaches a predetermined finishing moisture level by a preset desired finishing drying time. It is dried and the drying work 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.

[Example] An example of the grain drying method according to the present invention will be described with reference to the drawings.

When loading a predetermined amount of grain to be dried into the grain dryer and starting drying, the operator performs the following operations.

First, the operator sets a convenient time (date and time) as the scheduled drying finish time A depending on the work schedule and the like. The current time B 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 A and the current time B.

On the other hand, by measuring the initial moisture content D of the grain to be dried and setting the drying finish moisture content E of the grain, the possible drying speed F can be calculated from the moisture content to be dried and the drying time C. This possible drying rate F is
It is displayed only to the extent that the grain does not crack or become insufficiently dry.

Therefore, if the operator selects the desired drying speed G within the displayed range of possible drying speeds F,
The time required for drying, that is, the required drying time H, is calculated, so calculate the time corresponding to the time calculated by calculating the required drying time H from the scheduled drying finish time A, and set this as the drying start time I. (make a reservation.

Thus, if the grain dryer is automatically operated according to the set control conditions, grain drying will be completed by the desired time.

The possible drying speed F is displayed in steps of, for example, 0.1% depending on the drying rate (moisture reduction rate per hour), and the drying speed is determined by selecting one of them. It will be more convenient if you do this.

[Effects of the Invention] According to the present invention, even if a desired drying finish time is set in advance before the start of drying and any possible drying speed is selected, the set time can be set without causing shell cracking or insufficient drying. This provides the effect that drying can be completed by the scheduled drying finish time.

Claims (1)

[Claims] 1. Before starting drying, the operator first sets the desired drying finish scheduled time, then calculates the possible drying time from the current time constantly measured by the clock device to the above drying scheduled time, and also calculates the initial drying finish time of the grain. A possible drying speed is calculated from the moisture content and drying finish moisture, etc., and then the drying start time is set from the drying time determined by the selection of the drying speed within the calculated possible drying speed range, and automatic drying is performed. A grain drying method characterized by:
