Refrigerator for grain

[0017] To achieve the above objects of the present invention, there is provided a grain refrigerator provided with a receiving container, a grain storage part installed in the receiving container, for storing a grain, and an evaporator forming a cooling cycle to keep the stored grain at a low temperature, wherein the evaporator is at least one or more and is installed in a grain storage space of the grain storage part to cool the stored grain.

[0018] One of the evaporators may be installed at a center of the grain storage part in a spiral shape in a length direction, or may have a plurality of bent portions on a plane of a multi-layer structure such that the respective layers of the plane are connected by an interconnection part such that a refrigerant of the one or more evaporators is circulated.

[0019] Preferably, the evaporator receiving part may be received by an evaporator receiving part formed of a material containing moisture. Alternatively, the evaporator may be coated with a c
