[0005] In view of this, the present invention provides a sugar extraction device for stevia processing, which has an extrusion plate that automatically squeezes the stevia raw material during cleaning of the filtered material. When the operator opens the sealing plate to clean the extracted stevia raw material, the opening of the sealing plate drives the first bevel gear to rotate. The rotation of the first bevel gear drives the second bevel gear to rotate, which in turn drives the transmission shaft to rotate. The rotation of the transmission shaft drives the first gear to rotate, which in turn drives the second gear to rotate. During the rotation of the transmission shaft, the second pulley rotates, which in turn drives the transmission belt to rotate the first pulley. During the rotation of the first pulley, the incomplete gear rotates. When the sealing plate is fully open, the incomplete gear rotates exactly 180 degrees. During the rotation of the incomplete gear, the control gear rotates, which causes the extrusion plate to flip and squeeze the auxiliary torsion spring, so that the extrusion plate squeezes the stevia raw material filtered through the filter screen.

Beneficial effects

[0012] In this invention, when cleaning the extracted stevia raw material, the worker opens the sealing plate to clean it. As the sealing plate opens, it drives the first bevel gear to rotate. Subsequently, through a series of transmissions, it drives the incomplete gear to rotate. As the incomplete gear rotates, it drives the control gear to rotate, causing the control gear to rotate and rotate the extrusion plate to squeeze the auxiliary torsion spring. This causes the extrusion plate to squeeze the stevia raw material filtered through the filter screen, squeezing out as much residual sugar as possible from the stevia raw material. This improves the sugar extraction rate, reduces resource waste, and lowers the difficulty of subsequent processing, effectively improving the practicality of the sugar extraction device.

[0013] During the feeding process of stevia raw materials, the drive motor is started, which drives the right crushing roller to rotate. As the right crushing roller rotates, the left crushing roller is driven to rotate through the meshing of two transmission gears. The rotation of the two crushing rollers crushes the stevia raw materials, which facilitates the extraction of sugar from the stevia and effectively improves the convenience of the sugar extraction device.

[0031] The specific usage and function of this embodiment are as follows: The extraction tank body 1 is supported by the support column 101, the solvent is injected through the liquid inlet pipe 107, and the stevia raw material is injected through the feed rack 108. Then, the control motor 102 is started, causing the control motor 102 to drive the stirring shaft 103 to rotate.

The rotation of the incomplete gear 122 drives the control gear 121 to rotate, causing the control gear 121 to rotate and cause the pressing plate 119 to flip and press the auxiliary torsion spring 120, thus causing the pressing plate 119 to filter the filter screen 129.
