Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to grain drying and preparation equipment such as country elevators.

In this type of facility, the rice husks discharged from the removal equipment installed in the hulling and sorting process are usually stored in a rice husks store, and the rice husks are incinerated in an incinerator or transported by truck and disposed of. Therefore, the equipment costs for rice husks and incinerators increased, and they also required a large installation area. Furthermore, most of the fuel used in the drying equipment was petroleum, and the cost of that fuel was enormous.

In order to solve the above-mentioned drawbacks, the present invention uses an empty silo as a rice husk tank, and also installs a rice husk combustion device that uses rice husks as fuel and connects it to the silo and drying device. To provide a device that can effectively utilize a silo, greatly reduce fuel costs, and burn high-quality rice husk charcoal.

The present invention will be explained with reference to embodiment figures. Reference numeral 1 designates a country elevator in which a plurality of silos 2, 2'...2 ⁿ , a cargo receiving device 3, a tempering tank 4, a drying device 5, a removing device 6, a sorting/weighing device 7, etc. are arranged. Each of the silos 2, 2'...2 ⁿ
An inlet conveyor 8 for transporting and supplying paddy and rice husks is installed horizontally at the top of the silo, and an elevator 10 is installed upright on one side of the silo, and a drying device for paddy is installed at the bottom of each silo 2, 2'... ²ⁿ . 5. A discharge conveyor 9 is installed horizontally to convey the product to a removal device 6, etc. The paddy transported from the arbitrary silo to the removing device 6 is removed,
The brown rice is conveyed to the next step, the sorting and weighing device 7, and the rice husks are conveyed to the rice husk reserve tank 17 via the flow path 16 via the switching valve 11, and the other side is comprised of the conveyor 8 and the flow path 12. The rice husk conveyance path A is configured to supply the empty silo, and a rice husk combustion device 13 and a liquid combustion device 14 are installed in parallel near the drying device 5, and each combustion device 13, 14 is connected to a switching device 15. Hot air is supplied to the drying device 5 through the drying device 5. In addition, the supply section of the rice husk combustion device 13 is provided with the reserve tank 17, and the rice husk discharge passage B consisting of the conveying fan 18 and the flow passage 19 is connected to the extraction ports 20, 2 provided at the lower part of each of the silos.
0'...20 Contacting ⁿ . 21 is a cyclone collector that separates air and rice husks.

With the above-mentioned configuration, the raw material paddy is conveyed to the tempering tank 4 or drying device 5 through the receiving device 3, and the circulation process is repeated until it is tempered to a predetermined moisture value (around 17%), and then transferred to an arbitrary silo. It will be brought in. If necessary, it is tempered to the specified moisture content (15%) by finishing drying, and then further selected and weighed before being stored in a silo. The dried paddy in the silo is shipped as brown rice after undergoing a de-processing, sorting and weighing process. is switched to the flow path 16, stored in the rice husk reserve tank 17, and used in the rice husk combustion device 13, and when each of the above operations progresses and any silo becomes empty, the switching valve 11 is switched to the rice husk conveyance path A. The rice husks are stored in the silo, and the rice husks stored in the silo are supplied from the take-out part to the rice husks combustion device 13 through the rice husks discharge path B and burned to burn the rice husks smoky coal. Regarding the combustion device of the drying device 5, in the first stage or when there is no rice husk, the switching device 15 provided in the hot air path of the drying device is switched to the liquid combustion device 14 to cause combustion and supply hot air. Also, as the work progresses and the rice husks are stored in the reserve tank and silo, the switching device 15 of the drying device is activated.
By switching to a rice husk combustion device and supplying the hot air generated by the device to the drying device, there is almost no need to use liquid fuel such as petroleum, resulting in a significant reduction in fuel costs. Since storage and incinerators are not required, equipment costs are low and equipment space is not required.Also, since the empty silo was also used as a rice husk tank, the silo can be used effectively, and the rice husks with a certain moisture content can be stored in the rice husk tank. Since it can be supplied to a combustion device, it has the effect of being able to burn high-quality rice husk smoky charcoal.
