Description

[Detailed explanation of the invention] "Industrial application field" This invention targets grains such as rice and wheat,
This relates to grain communal drying facilities such as rice centers, country elevators, dry stores, etc., which are comprised of a receiving section, drying section, storage section, preparation and shipping section, etc.

``Prior Art'' Conventionally, as shown in Japanese Utility Model Publication No. 60-29700, there was a technique of removing the hulls from paddy, sorting them into regular brown rice and waste rice, and weighing each of them.

``Problems to be solved by the invention'' In the prior art, a part of the raw paddy collected at the receiving section was dried to a set moisture content and then processed as sample paddy by the prior art. The handling of sample paddy requires manpower and time, it is not easy to save labor in the receiving work and self-inspection work that is done for each individual/consignment, and the receiving efficiency of the facility cannot be easily improved. There was a problem.

In addition, as shown in Japanese Patent Publication No. 56-19569, there was a technique for automatically taking out a certain amount of grains as a sample using a reducing device, but some of the grains in the receiving section were Even if sample grains are taken out by a separator, there are problems in handling operations, such as the need to manually carry the sample grains from the reductor to a dryer and feed them into the dryer.

``Means for Solving the Problems'' However, the present invention consists of a reduction fractionator that takes out a part of the grains after weighing from the receiving and weighing section for joint drying of grains, and a predetermined amount of sample grains after receiving and weighing the grains. a sampler that receives the sample from the condenser and sends it to the sample dryer;
and a sample dryer that dries the sample grains from the sampler to a predetermined moisture content and automatically carries them out, and a part of the grains after receiving and weighing is taken out and dried to form sample grains with a predetermined moisture content. This feature is characterized in that it is configured to automatically perform the tasks to be performed.

"Operation" Therefore, by carrying the grains into the receiving and weighing section, a predetermined amount of sample grains is automatically carried into the sample dryer, and sample grains with a predetermined moisture content are taken out from the sample dryer. This eliminates the need for manual work such as transporting and loading sample grains into a sample dryer, and fully automates pre-processing work for self-inspections such as taking out and drying sample grains, improving self-inspection efficiency and reducing self-inspection costs. In addition to centralizing control of grain drying facilities and simplifying the management of receiving operations, it is possible to eliminate human errors such as misidentifying the consignor or consignee of sample grains, and to improve the efficiency of receiving and autonomously. This allows work such as inspections to be carried out safely.
