A conventionally known circulating grain dryer, for example, as disclosed in Japanese Patent Application Laid-open No. 55-31264, has a storage section for storing and tempering grain, and a hot air generated by a burner and a fan. Some types have a drying section that dries the grain by contacting it, a feeding mechanism installed at the bottom of the drying section that feeds out the grain, and a circulation device that transfers the grain fed from the drying section to a storage section. Grains are dried with hot air in a drying section, then tempered in a storage section, and this process is repeated several times to dry to a predetermined moisture content. this is,
This is because if too much water is dried at one time, phenomena such as shell cracking will occur, so it is necessary to equalize the water content of tempered rice husks and brown rice and gradually reduce the water content. Therefore, the amount of grain passing through the drying section per unit and the maximum grain storage capacity of the storage section are determined by the time required for the grain dried in the drying section to circulate and temper before being dried again. It is set to ensure that

However, the dryer is designed to accommodate this maximum grain storage capacity, and the amount of grain delivered (passed through) in the drying section is always constant relative to the volume of the storage section.
In the case of so-called rounding, in which the amount of grain charged into the storage section is small, the time it takes to pass through the drying section and reach the drying section again becomes shorter, reducing the time required for grain tempering, and reducing the quality of the paddy. Damage such as shell cracking occurred. In order to prevent these inconveniences, the temperature of the hot air in the drying section is lowered to reduce the drying loss rate during one pass through the drying section to the extent that sufficient tempering can be achieved even with a short tempering time. The above damage was resolved. In this way, the drying loss rate of the paddy per pass through the drying section is reduced, so in order to dry the paddy to a predetermined moisture content, the number of times the paddy is circulated must be increased. It had the consequences that it had to do. Therefore, when the loading amount is small, more mechanical impact is applied to the grain, resulting in a higher drying loss rate and increased damage. Moreover, there was no significant difference in the time required for drying compared to when the maximum amount of filling was applied, and energy consumption increased.

is connected to two poles, and in order to rotate the fan at high speed, the drive motor 14 is connected to four poles, each of which rotates at high speed.Furthermore, the set hot air temperature, which is the reference setting value for the hot air temperature, is also set to a high temperature to generate hot air. The amount of fuel supplied to the vessel 2 is increased, the grains are dried at high temperature and with a large air volume, and the circulation speed is also increased. Thereby, while increasing the drying rate per unit time, the drying section passage time can be shortened and the drying rate per circulation can be maintained at a predetermined value.

乾燥しにくくなることに対応した措置である。[When the loading amount is between 60% and 20%] When the loading amount is set using the loading amount setting switch 27, the moisture content of the grain is determined by the moisture content detection device 29.
When it exceeds 21%, the circulation motor 15 is connected to 4 poles and rotated at a medium speed in order to set the circulation speed to a medium speed.
In order to rotate the fan at high speed, the drive motor 14 is connected to four poles and rotated at high speed, and the set hot air temperature is set to standard, so that the hot air temperature and air volume are standard, and the circulation speed is also standard (medium speed). Compared to when the loading amount exceeds 60%, the drying loss rate per unit time is slightly lower, but the longer time it takes for the grain to pass through the drying section, the grain can be dried at the specified drying loss rate per cycle. be exposed. Also, when the moisture content of grain is less than 21%,
The circulation speed is medium speed, the drive motor 14 is connected to 8 poles to make the fan slow, and the set hot air temperature is set to standard. Therefore, the amount of fuel supplied to the hot air generator 2 is reduced, and drying is performed with a further reduced drying loss rate. This is a measure taken in response to the fact that when the moisture content of grains decreases, it becomes difficult to dry them.

よい。[When the filling amount is 20% or less] When the filling amount is set using the filling amount setting switch 27, if the moisture content exceeds 21%, the circulation motor 15 is connected to the 6-pole in order to reduce the circulation speed. Then, in order to rotate the fan at high speed, the drive motor 14 is connected to four poles, and the set hot air temperature is set to a low temperature to circulate the hot air at a low temperature standard air volume at a low speed, thus increasing the time for passing through the drying section. Drying is performed by keeping the drying loss rate per pass at a predetermined value. Further, when the moisture content is 21% or less, the drive motor 14 is connected to 8 poles in order to further reduce the fan speed, and a small amount of low-temperature hot air is circulated at a low speed. As explained above for each case, the above-mentioned increase/decrease in circulation speed is based on a low speed: medium speed: high speed ratio of approximately 2:3:6, and when the fan rotation is high speed and low speed, the air volume ratio is approximately 2. :1, high-speed rotation is the standard, and the set hot air temperature is preferably increased or decreased by about 4° C. when the temperature is high or low relative to the standard temperature when performing calculation processing control. The invention of this embodiment combines the above-mentioned increases and decreases in circulation speed, air volume, and set hot air temperature, and reduces damage caused by grain circulation by reducing the circulation speed as the amount of charged air decreases. In order to prevent this, and to keep the drying loss rate per circulation approximately constant as the circulation speed decreases, the temperature of the hot air is lowered.
Alternatively, reduce energy consumption by reducing fan rotation speed. By the way, when reducing the fan rotation speed to halve the air volume, not only noise generation but also energy consumption, that is, power consumption, decreases.
The 0.75KW is reduced to 0.1KW. In the explanations so far, in order to keep the drying loss rate per circulation constant, the temperature and air volume of hot air are adjusted as a means of reducing the drying loss rate per unit time, and the classification of the amount of filling is explained. Depending on the hot air temperature,
Although it has been explained that the air volume is adjusted according to the moisture content classification, this is only a preferable and convenient means, and in particular, the hot air temperature can be infinitely controlled. I don't get caught up in it. A comparison between the invention and the actual values of this embodiment and the conventional one is shown in the attached table.From this, it can be seen that in the invention of this embodiment, the amount of filling is small, the number of circulations does not change significantly, and the consumption of fuel and electricity is reduced. It can be seen that less is required. In this embodiment, the number of poles of the drive motor 14 and the circulation motor 15 are varied in order to vary their rotational speeds. A stepwise control method may also be used. Further, although the setting of the filling amount is performed manually, it may be configured such that a filling amount detection means is provided in the storage section 6 to automatically set the setting.

As is clear from the above-mentioned embodiments, the present invention controls the hot air volume, delivery amount, and set hot air temperature according to the grain loading amount, and keeps the drying loss rate per circulation constant. Even when the amount is small, it is possible to prevent damage caused by mechanical impact on grains and shell cracking due to rapid drying, and energy consumption, time required, and noise generation during operation are also reduced compared to when the grain is loaded to maximum. becomes possible.
