This utility model discloses a preservation device for processing agricultural and sideline products, including a preservation box with multiple vertically distributed storage compartments fixed inside. A rotating shaft, rotating in tandem with the storage compartments, is rotatably connected inside the preservation box. Multiple leveling components, corresponding to the storage compartments, are fixed to the outer wall of the rotating shaft. This preservation device for processing agricultural and sideline products achieves synchronous processing of materials in multiple storage compartments by driving the rotating shaft and the multiple leveling components to rotate synchronously through the rotating components. Through the linkage of the rotating plate, elastic component, mounting plate, and leveling rod in the leveling component, the rotational motion is converted into a gentle leveling and agitating action on the surface of the materials. The elastic component ensures that the force when the leveling rod contacts the materials is flexibly adjustable, effectively turning the materials while avoiding mechanical damage to the surface of agricultural products from rigid impacts. This spreads and disperses accumulated agricultural and sideline products, facilitating their preservation and improving their preservation effect.
