Title:
APPARATUS FOR PRESERVING GRAIN
Document Type and Number:
Japanese Patent JP2003189790
Kind Code:
A
Abstract:

To provide an apparatus for preserving grains such as rice to dispense a small amount of the stored grain at a time while essentially preventing the deterioration of the grain quality.

This preserving apparatus is provided with a closed vessel 10 holding the grains such as rice and filled with nitrogen gas supplied from a nitrogen gas cylinder 34. A prescribed amount of the grain is discharged from the vessel 10 by opening a valve 28 and energizing a blower 32. A control valve 38 is opened or closed according to the inner pressure of the vessel detected by a pressure sensor 42 and the supply of the gas from the nitrogen gas cylinder 34 is controlled to keep the pressure in the vessel 10 to a prescribed level by a control unit 50. The vessel 10 is constantly maintained in the closed state and the nitrogen gas is supplied to the closed vessel according to the amount of the discharged grain. Accordingly, a necessary amount of rice can be supplied without breaking the closed state of the vessel while keeping the initial quality of the rice until the closed vessel 10 becomes empty.
