Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain drying control system for grain processing equipment.

[0002]

2. Description of the Related Art Conventionally, grains supplied to a receiving device and received are supplied to a dehumidifying and drying type of grain dryer depending on the type of product and dried, or supplied to a hot air drying type of grain dryer. The dried grains are transferred to the grain storage tank and stored, and then supplied from this storage tank to a huller to be hulled and sorted into brown rice and rice husks. Are separately discharged to the outside of the machine, but the quality of the grain is detected at the time of receipt, and the dehumidification is not controlled by the dehumidification drying method or the hot air drying method by this detection quality. The drying method was controlled by drying or hot air drying.

[0003]

In the grain processing apparatus, the grain supplied to and received by the cargo receiving unit is transferred to a dehumidifying and drying type grain dryer depending on the type of the grain, or is dried with hot air. It is supplied to the grain dryer of the method, is dehumidified while circulating in these dryers, or is dried with hot air, and the dried grains are transferred and stored to the grain storage tank for each type, and stored from this storage tank. The grains are supplied to a huller, hulled, sorted into brown rice and rice husk, and the brown rice and the rice husk are separately discharged outside the machine.

[0006] In this grain drying method, the quality of the grain is detected by a quality detecting device, and the dehumidifying and drying method, which requires a long drying time and cost, is detected as a variety having a good taste and high quality. It is intended to dry effectively by using only the grains.

[0005]

Therefore, the present invention provides
The quality of the grain to be received by the receiving device 1 is classified into the high quality grain, the standard grain and the poor grain by the quality detecting device 2 and detected, and dried by the dehumidifying drying method or the hot air drying method by the grain dryer 3. The dried grain is supplied to the grain storage tank 4 to supply the dried grain to the storage tank 4.
In the grain processing apparatus that supplies the grain from the hulling machine 5 to hull it, the good quality grain, the standard grain, detected by the quality detecting device 2,
And a grain drying control, characterized in that the drying in the dryer 3 is controlled by a deselecting means such as the dehumidifying drying method or the hot air drying method based on the detection result of the coarse grain and dried. The system configuration.

[0006]

In the grain processing apparatus, the grain supplied to and received by the cargo receiving unit 1 is supplied to the quality detecting unit 2 for detecting the quality of the grain, and the quality detecting unit 2 adjusts the grain size and damages the grains. ,
Based on the content of dead rice, colored grains, grains of different varieties, foreign substances, etc., the grains were detected by classifying them into high quality grains, standard grains and poor grain, and the grain quality was detected. hand,
For example, grains with good taste and good quality are transferred to the dehumidifying / drying type grain dryer 3, and grains with poor taste and standard and poor quality are dried with hot air. System is transferred to the grain dryer 3 and dehumidified while being circulated in the dryer 3 or dried with hot air. The dried grains are transferred to the grain storage tank 4 for storage according to the variety and grade. Then, the rice is supplied from the storage tank 4 to the huller 5 and hulled, sorted into brown rice and rice husk, and the brown rice and the rice husk are separately discharged out of the machine.

[0007]

According to the present invention, the grain is classified into varieties and grades, and the varieties and grades are classified into the dehumidifying and drying method and the hot air drying method to dry the grain.
Good quality grains with good taste can be dried efficiently by dehumidifying and drying method so that the grain can be efficiently dried without deteriorating the taste and quality. Since it is the main type, it is not possible to sort out dead rice, rice gruel, etc. during drying. Considering these things, it is desirable to use the dehumidifying and drying method for good quality grains beforehand.

The grains of the part are supplied to the quality detecting device 2, and the quality detecting device 2 detects the grains by classifying them into good quality grains, standard grains and poor quality grains, and then the feeding transfer device 9
Dehumidifiers 2 according to the quality of the grains transferred and classified by
4, the hot air device 25 and the sorting device 29 are installed in the grain storage chamber 15 of each grain dryer 3, and the storage chamber 15
The grains stored inside are dried by being exposed to dehumidifying air and hot air while flowing down from the storage chamber 15 to the grain drying chamber 16, and are fed down to the lower portion by the feeding valve 17 and flowed down from the collecting trough 20. It is supplied to the circulating grain raising machine 30, is conveyed to the upper part by the circulating grain raising machine 30, and is transferred from the throw-out cylinder 31 through the transfer gutter 21 to the diffuser 2
3 and is uniformly diffused / reduced into the storage chamber 15 by the diffusion plate 23 and circulated and dried. When the moisture sensor 33 detects the same grain moisture as the finish target moisture, the grain drying is completed. To be done.

In addition, during the drying, in the dryer 3 equipped with the sorting device 29, the rice gruel in the dry grain is removed by the sorting device 29, and the quality of the grain is further improved. The dried grain is discharged from each of the dryers 3 to the discharge transfer device 10 according to grade, and is supplied from the discharge transfer device 10 to the grain storage tank 4 through the discharge sublimation machine 11 and is stored therein. It is supplied from the tank 4 to the huller 5, hulled by the huller 5 and sorted into hulls and brown rice by a hulling sorting device, and the hulls are passed from a hulling fan 37 to a hulling discharge pipe 38 to The rice is discharged to the outside, and the brown rice is fried by the grain hulling machine 39 and discharged to the outside.
