Description

[Detailed Description of the Invention] "Industrial application field" The present invention targets rice, wheat, soybeans and the like as a target grain,
The present invention relates to a grain drying facility such as a country elevator composed of a drying section, a storage section, and a preparation and shipping section.

[Prior Art] Conventionally, as shown in JP-A-63-302955, there are facilities provided with a dryer and a silo.

"Problems to be Solved by the Invention" The conventional technique involves transporting cereals having uneven moisture from a storage bin to a dryer, because the grain put into a storage bin has a difference in moisture depending on the cargo port. It is necessary to repeatedly dry grains with non-uniform water content to prevent quality deterioration, and it is not possible to easily perform grain moisture check, drying temperature management, and simplification of transporting work, thereby saving labor and reducing processing costs. Is not easily achieved.

`` Means for solving the problem '' Accordingly, the present invention provides a storage bin for charging the weighed grain received by the receiving unit, a grain drying tank for charging and drying the grain in the bin, and a silo for storing the grain. In the grain drying facility to be provided, a dryer take-out member that carries the grain in the storage bin and the grain in the grain drying tank into the silo, and a silo take-out member that carries the grain in the silo into the grain drying tank or the storage bin are provided, and the grain is dried. It is characterized in that a plurality of dry air generators are provided for separately supplying the room temperature and constant humidity air to the storage bin and the grain drying tank.

[Operation] Therefore, since the grains in the storage bottle are dried to substantially uniform moisture by the constant-temperature, constant-humidity air, it is easy to simplify the drying work to make the dried grains suitable for long-term storage, saving labor and reducing processing costs. In addition to easy storage and storage of grains for a long period of time using storage bins and grain drying tanks, the use of room temperature and constant humidity air easily prevents deterioration in hot and humid periods such as summer and deterioration due to condensation in winter. And the long-term storage of the grain can be easily maintained at a high quality.
