GRAIN POLISHING PLANT AND CONTROL METHOD FOR GRAIN POLISHING PLANT

摘要

To provide a grain polishing plant capable of efficiently polishing grains of a very small amount of materials even by a large-sized grain polishing device efficiently by generating no loss, and by generating no unevenness (in a target quality by performing neither two stirs nor three stirs), and a control method for grain polishing plant.SOLUTION: A grain polishing plant according to the present invention comprises a raw material tank, a storage container, a grain polishing device connected with the exhaust port of the raw material tank and the exhaust port of the storage container, a transportation route that transports grains exhausted out of the exhaust port of the grain polishing device to a next process, a switching device provided halfway in the transportation route, and a recovery route that recovers grains exhausted out by branching from the switching device, where the storage container stores grains exhausted out of the grain polishing device, until the grain polishing degree reaches a predetermined grain polishing degree, in an order of being exhausted out of the grain polishing device, and supplied to the grain polishing device by a first-in first-out system.SELECTED DRAWING: Figure 1
