[0030] The fruit is put into the crushing device 1, and the pulp crushed by the crushing device 1 enters the temporary storage device 2, and then is sent to the extrusion device 3 by the temporary storage device 2. After extrusion once, the filter replacement device 4 replaces the new filter component, and the juice after the pulp is squeezed directly enters the fermentation device 5, and is stirred and aerated at the same time in the stirring and aeration part to accelerate the reproduction of yeast. At the same time, stirring is also performed while aerating to make the yeast fully mixed with the juice, which is beneficial to the subsequent fermentation process. By setting the filter replacement device 4, the filter component can be replaced, which avoids too much pulp from entering the juice during the extrusion process, saves the process, and provides convenience for the brewing of fruit wine.

[0031] A further optimized solution is that the crushing device 1 includes a crushing shell 101, which is installed on a bracket. A crushing shaft 102 is rotatably connected inside the crushing shell 101. One end of the crushing shaft 102 passes through the top surface of the crushing shell 101 and is rotatably connected to the output shaft of a crushing motor 103. The crushing motor 103 is installed on the crushing shell 101. The bottom of the side wall of the crushing shell 101 is connected to the temporary storage device 2, and a plurality of crushing blades 104 are fixedly connected to the side wall of the crushing shaft 102.

[0033] A further optimized solution is that the temporary storage device 2 includes a temporary storage box 201, which is installed on a bracket. The side wall of the temporary storage box 201 is connected to the bottom of the side wall of the pulverizing shell 101. A first valve 202 is provided on the pipeline connecting the temporary storage box 201 and the pulverizing shell 101, and the temporary storage box 201 is connected to the side wall of the extrusion device 3.

[0034] A further optimized solution is that the extrusion device 3 includes an extrusion shell 301, which is installed on a bracket. The side wall of the extrusion shell 301 is connected to the temporary storage box 201, and a second valve 203 is provided on the pipeline connecting the temporary storage box 201 and the extrusion shell 301. The top surface of the extrusion shell 301 is vertically slidably connected to an extrusion rod 304, and an extrusion block 303 is installed at the bottom end of the extrusion rod 304. The extrusion block 303 is in sliding contact with the inner wall of the extrusion shell 301, and the top end of the extrusion rod 304 is fixedly connected to the output end of the extrusion cylinder 305, and the extrusion cylinder 305 is installed on the bracket. The bottom end of the extrusion shell 301 is in sealing contact with the top surface of the filter replacement device 4.

[0035] By controlling the opening and closing time of the second valve 203, a fixed amount of pulp in the temporary storage box 201 flows out at a time into the extrusion shell 301. Under the force of the extrusion cylinder 305, the extrusion block 303 squeezes the pulp, and the juice flows into the fermentation device 5 through the filter replacement device 4. After squeezing once, the filter replacement device 4 replaces the new filter component, and the above process is repeated again for squeezing.

[0037] This arrangement allows the extrusion block 303 to rotate along the spiral chute 302 during the extrusion process, which can further enable the rotational force to act on the pulp in the pulp, thereby strengthening the force on the pulp and making the juice yield of the extrusion higher.

[0038] A further optimized solution is provided, wherein the filtering and replacing device 4 comprises a turntable 401, the bottom center of which is fixedly connected to the output shaft of a rotating motor 406, the rotating motor 406 being mounted on a bracket, a plurality of connecting rods 402 being fixedly connected to the side wall of the turntable 401 at equal intervals in the circumferential direction, the end of the connecting rod 402 away from the turntable 401 being rotatably connected to a rotating rod 403, a flipping motor being mounted between the rotating rod 403 and the connecting rod 402, the end of the rotating rod 403 away from the connecting rod 402 being fixedly connected to a mounting sleeve 404, a filter plate 405 being placed on the bottom surface of the mounting sleeve 404, the top surface of the mounting sleeve 404 being in contact with the bottom surface of the extrusion shell 301, the inner wall of the mounting sleeve 404 being of the same shape and flush with the inner wall of the extrusion shell 301, and the bottom surface of the mounting sleeve 404 being in contact with the top surface of the fermentation device 5.

[0039] After one extrusion, pulp remains on the filter plate corresponding to the extrusion shell 301. At this time, the rotating motor 406 is started, and a new filter plate 405 is placed in the next installation sleeve 404 and moves to the extrusion shell 301. When the next extrusion is performed, the installation sleeve 404 with pulp has left the extrusion shell 301. The flip motor is controlled to rotate, and the installation sleeve 404 flips over and the filter plate 405 falls off. After the filter plate 405 falls off, the flip motor is controlled to rotate again to make the installation sleeve 404 turn forward. At this time, a new filter plate 405 is added inside it and it can be reused.

[0040] Further optimization scheme, the fermentation device 5 includes a fermentation shell 501, the top surface of the fermentation shell 501 is provided with a feed pipe, the top surface of the feed pipe is in contact with the bottom surface of the mounting sleeve 404, the stirring aeration part includes a hollow shaft 502 rotatably connected to the bottom surface of the fermentation shell 501, the outer side of the hollow shaft 502 is fixedly connected with a spiral blade 503, the interior of the spiral blade 503 is a hollow structure, and a plurality of air outlet holes 511 are opened on the spiral blade 503, and the air outlet holes 511 are connected to the interior of the hollow shaft 502.

The driving gear 507 is connected to a drive motor 508. The drive motor 508 is installed on the fermentation shell 501. The bottom end of the hollow shaft 502 is rotatably connected to a connecting sleeve 504.

At this time, the pressure relief valve 509 is in an open state. After the yeast reproduction meets the requirements, the pressure relief valve 509 is closed and vacuum treatment is performed through the exhaust pipe 510. An opening and closing valve needs to be set on the pipeline connecting the fermentation shell 501 and the installation sleeve 404 to ensure the vacuum state in the fermentation shell 501.
