Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0028] Embodiment 1

[0029] Based on the problem that the existing prior art is not thorough enough in dewatering stevia residue by centrifugal force, the embodiment provides a stevia residue dewatering machine, please refer to Figures 1-4 The embodiment provides a stevia residue dewatering machine, which can improve the dewatering rate of stevia residue. The stevia residue dewatering machine comprises a dehydration machine 2 installed on a bottom plate 1, a dehydration mechanism 3 for deep extrusion dewatering of stevia residue is arranged in the dehydration machine 2, a drying mechanism 4 for complete dewatering of stevia residue is arranged on the dehydration machine 2, the stevia residue is deep extrusion dewatered through the dehydration mechanism 3, so that the dewatering rate of the stevia residue is improved, and then the stevia residue after deep dewatering is dried in cooperation with the drying mechanism 4, so that the residual moisture in the stevia residue is completely dried.

[0030] Since the prior art is not thorough enough in dewatering the stevia residue by centrifugal force, the device is provided with a dewatering mechanism 3, which includes a rotating shaft 31 rotatably connected to a rotating hole formed in the dewatering machine 2, and an extrusion auger 32 mounted on the rotating shaft 31. A drain pipe 33 is mounted on the right side of the bottom of the dewatering machine 2, and an electric sealing valve 34 is mounted on the drain pipe 33. A drive motor 35 is mounted on the dewatering machine 2 to drive the rotating shaft 31 to rotate.

[0031] The dewatering machine 2 is obliquely mounted on the bottom plate 1, and the left side of the dewatering machine 2 is conical. The left end of the extrusion auger 32 is reduced synchronously with the conical structure of the dewatering machine 2. The drive motor 35 is started to drive the rotating shaft 31 to rotate, thereby driving the extrusion auger 32 to rotate and extruding the stevia residue to the left side of the dewatering machine 2, so as to deeply extrude and discharge the water in the stevia residue. The dewatering machine 2 is obliquely installed to the right side on the bottom plate 1, which is more convenient for the extruded water to be discharged through the drain pipe 33.

[0032] A feeding pipe 36 is mounted on the top of the dewatering machine 2, and a residue discharging pipe 37 is mounted on the left bottom of the dewatering machine 2. Electric sealing valves 34 are mounted on both of them. The stevia residue raw material is introduced into the dewatering machine 2 through the feeding pipe 36, and the completely dewatered stevia residue is discharged through the residue discharging pipe 37.

[0033] Example 2

[0034] Based on example 1, as shown in Figures 1-4 Since there is still some water in the stevia residue after extrusion dewatering, the device is also provided with a drying mechanism 4. The drying mechanism 4 includes an electric heating plate 41 mounted in a mounting cavity formed in the dewatering machine 2. A air dryer 42 is mounted on the top of the dewatering machine 2. Air supply pipes 43 are mounted on both sides of the air dryer 42. A plurality of high-speed nozzles 44 extending into the dewatering machine 2 are arrayed on the bottom of the air supply pipes 43. A shaking assembly 45 is arranged between the bottom plate 1 and the dewatering machine 2 to drive the dewatering machine 2 to tumble. After the stevia residue is extruded and dewatered, the drive motor 35 is started to drive the extrusion auger 32 to reverse, so as to reversely feed the stevia residue in the dewatering machine 2. In this process, the electric heating plate 41 is started to heat and dry the stevia residue, and the air dryer 42 is started to send hot air into the air supply pipe 43 and high-speed spray out through the high-speed nozzles 44, so as to blow away the stevia residue extruded into a group, thereby improving the efficiency of drying and dewatering.

[0035] Example 3

[0036] Based on example 2, as shown in Figures 1-4As shown, since the stevia residue groups after being squeezed and dehydrated are relatively firm, the high-speed airflow of the high-speed nozzle 44 cannot completely disperse the coagulated stevia residue groups, so the device is also provided with a shaking assembly 45, the shaking assembly 45 includes two groups of bearing seats 451 installed on the front and rear sides of the bottom plate 1, and a turnover shaft 452 is rotatably connected between each group of bearing seats 451, the turnover shaft 452 is provided with a driving gear 453, and the dehydrator 2 is provided with a driven gear ring 454 engaged with the driving gear 453, the bearing seat 451 is provided with a tumbling motor 455 for driving the turnover shaft 452 to rotate, the tumbling motor 455 drives the turnover shaft 452 to rotate in the bearing seat 451, and then drives the driving gear 453 on the turnover shaft 452 to rotate and drives the driven gear ring 454 on the dehydrator 2 to rotate, thereby driving the dehydrator 2 to overturn as a whole, in the process of overturning, the stevia residue groups repeatedly fall, thereby being shaken and dispersed, and the efficiency of drying and dehydrating is improved.

[0037] Since the dehydrator 2 is relatively sealed as a whole, when the stevia residue is dried and dehydrated, the steam evaporated therefrom accumulates in the dehydrator 2 and cannot be discharged, which affects the efficiency of drying and dehydrating, so the device is provided with an air vent on the top of the dehydrator 2, and a filter mesh 46 is installed in the air vent, the steam is discharged through the air vent, and the filter mesh 46 is used to intercept the stevia residue to prevent the stevia residue from falling.
