【発明の詳細な説明】 産業上の利用分野 この発明は、穀粒乾燥機の乾燥制御方式に関する。[Detailed description of the invention] Industrial applications The present invention relates to a drying control method for a grain dryer.

であった。Conventional technology In the past, grains were fed into a drying room and allowed to flow down, while drying was carried out by passing mixed dehumidified drying air, which is a mixture of dehumidifying air from a dehumidifying device and outside air sucked in from an outside air inlet. The drying control method was used to dry by controlling the outside air volume of the mixed dehumidified drying air during drying to a constant air volume without changing it depending on the elapsed time from the start of drying or the moisture content of the grains during drying.

の穀粒はこの混合除湿乾燥風に晒されて乾燥される。Problems to be Solved by the Invention While the grain is repeatedly circulated through the drying chamber of the grain dryer and flowing down, dehumidified air from the dehumidifier is sent to the drying chamber.
By passing the mixed dehumidified drying air mixed with the outside air taken in from the outside air inlet, the grains flowing down in the drying chamber are exposed to the mixed dehumidified drying air and dried.

装置を有効利用しようとするものである。During this drying process, when the moisture content of the grains is high in the early stage of drying, ventilation drying can achieve a certain degree of drying, which increases the intake of outside air during the early stage of drying to increase the drying effect and save energy. After that, when the grain moisture decreases and approaches the equilibrium moisture content, the outside air volume of the mixed dehumidifying drying air is reduced, and this mixed dehumidifying drying air is turned into a low dehumidifying air to improve drying efficiency. This is an attempt to make effective use of this dehumidification device.

Each part of the grain dryer 4, the dehumidifier 2, the moisture sensor 26, etc. are started, and the dehumidified air generated from the dehumidifier 2 and the outside air sucked from the outside air intake port 3 are mixed to become a mixed dehumidified dry air. , this mixed dehumidified dry air flows from the ventilation chamber 12 to the drying chamber 1.
The grains stored in the storage chamber 17 are absorbed by the hot air while flowing down from the storage chamber 17 through the drying chamber 1. The grains are exposed and dried, are fed out to the lower part by the feed valve 1l, flow down, are transferred from the grain collection gutter 10 through the feed gutter 24 into the grain hoisting machine 2l by the lower transfer spiral, and are fed to the packet conveyor 22.
It is conveyed to the upper part and supplied into the transfer gutter 9 through the dispensing tube 23, and from this transfer gutter l9, it is transferred and supplied onto the diffusion plate 20 by the upper transfer spiral, and from this diffusion plate 20 into the storage chamber l7. The moisture sensor 26 is evenly distributed, circulated and dried.
When the grain moisture content is the same as the finishing target moisture set by operating the moisture setting controller 40, the drying control device 42 of the operating device 6 automatically controls the drying machine 4 to automatically stop the grain moisture. Stop grain drying.
