[0017] The utility model has at least the following beneficial effects:

[0018] First, the drying structure of the utility model is designed according to the characteristics of asparagus slices / strips. By adjusting the height of the drying moving frame relative to the drying fixed frame, the asparagus slices / strips on each drying tray can be turned over for drying, realizing drying under normal temperature conditions, efficient turning over, increasing the heat exchange area, uniform drying, avoiding the influence of temperature and humidity on the quality, and improving the drying quality of asparagus.

[0019] Second, the cart body can be provided with walking wheels for easy movement. The frames are stacked on top of each other from bottom to top. One or more drying trays can be provided on each layer of the frame body. The drying fixed frame and the drying moving frame can be provided with walking wheels for easy movement. Cooperating with the cart body, the drying fixed frame is in a door-shaped structure, with a width and height greater than the cart body, facilitating the formation of an enclosed structure. The axle of the fixed frame power gear is installed on the drying fixed frame through bearings. The drying fixed frame has a clearance space for installing the fixed frame power gear. The fixed frame power motor drives the fixed frame power gear to rotate. The drying moving frame is in a π-shaped structure, with a width and height greater than the cart body and less than the drying fixed frame, facilitating the formation of an enclosed structure and cooperating with the drying fixed frame at the same time. The vertical rack provided on the drying moving frame meshes with the fixed frame power gear. When the fixed frame power gear rotates, the drying moving frame moves up and down with the vertical rack, driving the flap assembly to move up and down. In addition, the cross frame body of the drying moving frame is slidably connected with the guiding vertical groove to ensure the stable lifting of the drying moving frame. The number of flap assemblies can be set to multiple, with at least one corresponding to one drying tray. The turning shaft is sequentially connected to the flap, the turning block, and the turning motor, being fixed to the flap for driving the flap to rotate, being connected to the turning block through bearings for rotating relative to the turning block and moving horizontally synchronously with the turning block, and being fixed to the turning motor for driving the turning shaft to rotate.

[0020] Third, during use, the asparagus slices / strips are arranged on the drying tray, and the number of layers is adjusted according to requirements. When the material needs to be turned over after drying for a certain time, the drying fixed frame is moved to the outer periphery of the cart body, the height of the drying moving frame is adjusted to make the flap close to the lower drying tray, the angle of the turning shaft is adjusted to make the flap form an acute angle with the material, the flap contacts the asparagus slices / strips obliquely and stirs them, making the turning block move horizontally in one direction, raising the drying moving frame to make the flap away from the lower drying tray, adjusting the angle of the turning shaft to make the flap form an acute angle with the material, the flap contacts the asparagus slices / strips obliquely and stirs them, making the turning block move horizontally in the reverse direction, and the flap contacts the asparagus slices / strips obliquely and stirs them again. Repeat the operation several times to ensure that the asparagus slices / strips are fully turned over.

[0021] Fourth, the first plate body and the second plate body form an obtuse angle.

The second plate body contacts and stirs the asparagus slices / strips obliquely again, repeating the operation several times to ensure that the asparagus slices / strips are fully flipped, achieving secondary flipping. The transverse rack arranged on the vertical block body of the flipping block meshes with the power gear of the motor support. When the power gear of the motor support rotates, the flipping block moves horizontally along with the transverse rack, driving the flap to move horizontally. In addition, the horizontal block body of the flipping block is slidably connected to the guiding horizontal groove, ensuring the stable horizontal movement of the flipping block.

[0022] Fifth, the present utility model designs a mechanical skinning structure according to the characteristics of asparagus, removes the outer skin of asparagus, avoids the influence of high temperature and high humidity on the quality of asparagus, has less loss of the medicinal part, basically maintains the shape and hardness of asparagus, retains the active ingredients of asparagus, and provides a basis for subsequent drying.

[0023] Sixth, the skinning fixed support is of a U-shaped structure, forming an installation space for the skinning motor support and the power structure, and is the main load-bearing structure. The skinning motor support is of a square structure, and it can rotate relative to the skinning fixed support, that is, swing back and forth. The horizontal rotating shaft is connected to the skinning fixed support through bearings to achieve relative movement, and the horizontal rotating shaft is connected to the horizontal rotating shaft motor to achieve power drive. The door of the drying cylinder is used for feeding and discharging, and it can rotate relative to the skinning motor support, that is, swing left and right. The vertical rotating shaft is connected to the skinning motor support through bearings to achieve relative movement, and the vertical rotating shaft is connected to the vertical rotating shaft motor to achieve power drive. Alumina abrasive balls are arranged inside the drying cylinder, for example, with a size of 1 - 1.5 mm. By introducing a small amount of water, the asparagus and the alumina abrasive balls inside the drying cylinder interact to achieve mechanical skinning. The space planning of the skinning motor support is convenient for placing the horizontal rotating shaft motor and the vertical rotating shaft motor, avoiding interference movements with each other. Through pulley deceleration, it is convenient to control the rotation speed of the skinning motor support.

[0024] Seventh, during use, load fresh asparagus into the drying cylinder through the door, introduce a small amount of water to moisten the epidermis, start the vertical rotating shaft motor to make the drying cylinder rotate relative to the skinning motor support, and then start the horizontal rotating shaft motor to make the skinning motor support rotate relative to the skinning fixed support, making the asparagus inside the cylinder perform a compound spatial rotation movement, thereby achieving low-humidity skinning.
