【発明の詳細な説明】 「産業上の利用分野」 本発明は、もち籾を確実に白くはぜさせながら所定の仕
上り水分値に胴割れ発生もなく仕上げ乾燥することがで
きるもち籾乾燥方法およびその装置に関する。DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention provides a method for drying glutinous rice capable of finishing and drying the glutinous rice in a predetermined finished moisture value without causing cracks while surely causing the glutinous rice to be white. Regarding the device.

載されて知られている。“Conventional technology” Conventionally, by drying grains so that the grain temperature and the drying loss rate satisfy predetermined conditions, it is possible to surely prevent the occurrence of cracks in the barrel and the deterioration of the taste and efficiently obtain good dry grains. The grain drying method described above is known and described in, for example, Japanese Patent Publication No. Sho 59-14709 before the present application.
「発明が解決しようとする課題」 ところで、従前のこの種穀物乾燥方法によつて乾燥され

する問題点があつた。However, in the conventional drying method, during the drying operation, since no means for automatically detecting the rice paddy rate is used, after stopping the operation of the dryer by the completion of drying, There is an inconvenience that it is necessary for the operator to detect whether the rice glutinous rice is white or not, and when it is not white, to dry it again so that the rice glutinous rice can be whitened by restarting the dryer. However, there was a problem in that the rice husks were overdried due to the drying again, causing a cracking phenomenon.

停止回路とにより構成したものである。"Means for Solving the Problem" In order to achieve the above object, in the glutinous rice drying method of the present invention, the rate of swelling of dried glutinous rice during cyclic drying operation is sequentially detected and obtained. When the rate of swelling of rice glutinous rice exceeds the preset rate of swelling rate, the circulating drying work is automatically stopped and left for a certain period of time, and then collected. And a drying device for carrying out the above-mentioned drying method, a dryer for drying with hot air flowing through the glutinous rice in a circulating flow, and a part of the rice glutinous rice extracted with time from the dryer has a rate of warping. A crest rate detector for sequentially detecting, and a comparator circuit for comparing the rice hulls detection value detected by the cough rate detector and the crumple rate set value sent from the preset cough rate setting circuit, The automatic stop circuit is configured to automatically stop the dryer operation based on the signal from the comparison circuit when the comparison result of the comparison circuit indicates that the detected detection rate is equal to or larger than the set compression rate value.

て比較回路に送られ、比較される。[Operation] Now, after supplying a predetermined amount of glutinous rice, which is a grain to be dried, to the dryer, the glutinous rice is dried with hot air circulating while circulating and flowing in the dryer several times. Then, during the circulation drying operation as described above, a part of the glutinous rice is extracted with time from the dryer (for example, every one hour), and this is supplied to the wicking rate detector to wick the glutinous rice during drying. The rate is detected and the detection signal is sent to the comparison circuit. On the other hand, during the above-mentioned drying operation, it is more time-dependent (for example, every one hour) than the rate of heat setting circuit.
A standard value (for example, a moisture value of 1
4.5%, grain temperature 30 ° C) The set value of the spoil rate is sent as a signal to the comparison circuit and compared.

4.5%に乾燥されることになる。As a result, when the rice paddy haze rate detected over time with the progress of drying becomes the reference value or more, the comparator circuit sends a signal to the automatic stop circuit to activate the automatic stop circuit. The dryer operation is stopped at. Therefore, in this state, the mochi rice cake has a specified finished moisture value of 1
It will be dried to 4.5%.

よい。If the dryer operation is stopped as described above, if it is left for a certain time (for example, 24 hours) under the same condition, the difference in water content between the rice husks disappears and the natural phenomenon of swelling progresses. However, since all the glutinous rice will be whitened, it can be taken out from the dryer and collected in an appropriate place.
