The dried grains are removed at the huller 5 and they are selected into shells and unpolished rices and each of them is separately discharged out of the machine.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a tensioning operation control system for a grain drying adjustment device.

Conventional technology Conventionally, grains are loaded from a grain loading device into a plurality of grain driers and dried, and the dried grains sequentially discharged from the dryers are dried by a grain discharging device. The grains are transferred and discharged to a grain storage tank and stored there, and supplied from this storage tank to a huller, where they are removed, separated into rice husks and brown rice, and discharged outside the machine. In addition, these tensioning devices, dryers, discharge devices, paddy tanks, and hulling machines are centrally controlled by a central controller, but the tensioning of grains from the tensioning devices to the dryers is
This was a loading operation control system in which an operator selects an empty dryer capable of loading grain, and loads grain into the selected dryer.

Problems to be Solved by the Invention By operating the central control device 6, grains are sequentially loaded from the grain loading device into a grain dryer selected and set by the operator. As the circulation of flowing down the drying chamber is repeated, the hot air passes through the drying chamber, and the grains flowing down the drying chamber are exposed to this hot air and dried, and the dried grains are dried. The grains are sequentially discharged from each dryer to a grain discharging device, transferred to a grain storage tank by this discharge device, and stored therein, supplied from this storage tank to a grain hulling machine, and dried in this hulling machine. The grains are dehulled and separated into chaff and brown rice, which are discharged separately from the machine.

In this series of operations, the grain is loaded from the tensioning device to the dryer by the operator selecting the empty dryer in which the grain can be loaded, and then loading the grain into the dryer. However, the purpose is to automatically select and operate an empty dryer capable of loading grain, thereby simplifying the operation operations of the operator.

Means for Solving the Problems This invention provides a method for loading grains from a grain loading device 1 into a plurality of grain dryers 2 for drying the grains, drying the grains, and sequentially discharging the grains from the dryers 2.

These tensioning device 1, dryer 2, discharge device 3,
In a grain drying adjustment device that is equipped with a central control device 6 that centrally controls a storage tank 4, a huller 5, etc., when grain is being staked in the staked-out device 1, the grain is in an empty state where grain can be staked. This dryer I automatically determines that the dryer 2 is empty! The structure of the charging operation control system is characterized in that grains are loaded into the second.

Operation of the invention By operating the central control device 6, the operation information of the grain dryer 2 is read by the central control device 6, whereby the dryer 2 in an empty state capable of loading grain is selected. Then, the grains are sequentially loaded from the grain loading device 11 into this dryer 2 which is automatically selected and set, and this drying process is carried out.
As the circulation of flowing down in the drying chamber provided at the bottom of machine A 2 is repeated, the hot air passes through this drying chamber, and the grains flowing down in this drying chamber are exposed to this hot air and dried. The dried grains are sequentially discharged from each dryer 2 to a grain discharging device 3, transferred and discharged from the discharging device 3 into a grain storage tank 4 and stored, and from this storage tank 4 to a hulling machine 5. The dried grains are removed by the huller 5, separated into chaff and brown rice, and discharged separately to the outside of the machine.

Effects of the Invention According to the present invention, the grain dryer 2 is controlled by the central controller 6.
The operation information is read, and as a result, the dryer 2 in an empty state in which grain can be loaded is automatically selected, and the grain loading device 1 is transferred to the dryer 2 in the selected empty state.
