Small-scale rice drying experimental device

The invention discloses a small-scale rice drying experimental device. A rack is provided with a tempering chamber and a drying chamber from bottom to top. The top of the drying chamber is provided with a rice feed port and a drying circulation material inlet. The upper portion of an inner cavity of the drying chamber is provided with at least one exhaust pipe. Exhaust ports of the exhaust pipes communicate with corresponding first through holes in the sidewall of the drying chamber in a sealed mode. The lower portion of the inner cavity of the drying chamber is fixedly provided with at leastone air inlet pipe. Air inlets of the air inlet pipes communicate with corresponding second through holes in the sidewall of the drying chamber in a sealed mode and then are connected with a draught fan through a heating device. A rice discharge bin with a rice discharge wheel is arranged at a rice outlet of the bottom of the tempering chamber. The rice discharge wheel is driven by a driving device. A lower valve is arran
