The invention discloses a rice storage device, which comprises a box body, a sliding block inside the box body, and a rotating block inside the sliding block. The bottom end of the rotating block is fixedly connected with the top end of a thread rod, and the rotating block is in rotating connection with the sliding block. The threaded rod is in rotating connection with the sliding block. The baseplate of the box body is fixedly provided with a threaded sleeve. The bottom end of the threaded rod passes through the box body and the bottom end of the threaded sleeve to be fixedly connected to the top end of a handle. The threaded sleeve is screwed to the threaded rod. The bottom end of the box body is fixedly mounted with several brackets, wherein a fixing board is fixedly connected betweenthe brackets. The rice storage device is provided with the fixing plate between the brackets and a resistance wire is placed inside to ensure that the temperature at the bottom is kept at a suitable temperature for storing the rice. Moreover, by using an air blower introducing air into the inside of the box through a hollow rod, the rice can be effectively stored without being damaged by moisture.The sliding block is raised by rotating the threaded rod to ensure the beautiful layout of the rice.
