[0002] Fermented juice refers to juice made by fermenting the crushed pulp. Fermented juice retains the nutrition of the fruit to the maximum extent by fermenting the pulp, and a large amount of nutrients such as amino acids and short-chain fatty acids will be produced during the fermentation process; fermentation will also bring a large amount of probiotic metabolites, which is beneficial to the improvement of the intestinal environment and the enhancement of human immunity. After fermentation, fermented juice needs to go through a filtration and sterilization process to remove excess fungi and metabolites and preserve nutrients.

[0016] 1. The fully automatic sterilization equipment for fermented juice performs high-temperature sterilization in a sterilization tank, and after the sterilization is completed, the juice is sent to a cooling tank for rapid cooling, and then the cooled fermented juice is introduced into a collecting bin, so that the fermented juice enters the S-shaped liquid guide channel of the sterilization box through a liquid inlet to complete sufficient and continuous ultraviolet disinfection.

[0020] See also Figure 1-Figure 8 The present invention provides a technical solution: a fully automatic sterilizing device for fermenting fruit juice, comprising a sterilizing tank 1, a cooling tank 2 and a sterilizing box 3, wherein the cooling tank 2 and the sterilizing box 3 are arranged outside the sterilizing tank 1, a heat conducting coil 101 for circulating a heat conducting medium is installed in the interlayer of the sterilizing tank 1, and a cooling coil 201 for circulating a cooling medium is surrounded on the circumferential side surface of the cooling tank 2.

When the fermented juice is added into the sterilizing tank 1 through the feeding pipe 103, the photoelectric liquid level sensor 102 on the side of the sterilizing tank 1 detects the height of the juice level, thereby preventing the liquid level from being too high and directly contacting the bottom surface of the bottom shell 7, and preventing the foam removal roller 805 from absorbing too much juice liquid when rotating. At the same time, the photoelectric liquid level sensor 102 adopts a photoelectric liquid level switch of the brand Super Hua Mirror and the model LJ-1 / 2NPT, so that the photoelectric liquid level sensor 102 can detect the liquid level of the fermented juice sterilized at instantaneous high temperature; An inner cylinder mounted on the lower end of the sleeve 505 is fixed to the middle of the bottom shell 7, a water-blocking cover 701 is also fixed to the outer side of the bottom shell 7 near the inner cylinder, a through hole 702 is provided on the lower conical surface of the bottom shell 7, a defoaming mechanism 8 for rotating and scraping scum on the liquid surface is arranged inside the through hole 702, round arch strips 704 are fixed to the two ends of the bottom shell 7 near the upper side of the through hole 702, and the inner wall of the round arch strip 704 is integrally formed with a protrusion, the defoaming mechanism 8 includes an extrusion shaft 801 rotating with the two ends of the inner wall of the through hole 702, a small conical toothed disc 802 is fixed to one end of the extrusion shaft 801 extending through the inner cylinder, and defoaming rollers 805 are slidably connected to the two sides of the extrusion shaft 801; The bottom discharge port of the sterilizing tank 1 and the top feed port of the cooling tank 2, as well as the bottom discharge port of the cooling tank 2 and the top feed port of the collecting bin 301 are connected through a water pipe, and a water pump 4 is installed on the water pipe; a liquid inlet 302 is arranged on one side of the bottom of the sterilizing box 3, and a liquid outlet valve 306 and a discharge valve are connected to the upper and lower sides of the end of the sterilizing box 3 away from the collecting bin 301, respectively, and the upper surfaces of the lower guide plate 304 and the upper guide plate 305 are It is an inclined surface, one end of the lower drain plate 304 is fixed to the collecting bin 301, one end of the upper drain plate 305 is fixed to the inner wall of the sterilization box 3 near the liquid outlet valve 306, and liquid guide gaps are provided between the end of the lower drain plate 304 away from the collecting bin 301 and the inner wall of the sterilization box 3, as well as between the end of the upper drain plate 305 near the collecting bin 301, and an S-shaped liquid guide channel is formed inside the sterilization box 3 through the lower drain plate 304 and the upper drain plate 305.

[0021] During the specific implementation, the fermented juice is introduced into the sterilizing tank 1 through the feeding pipe 103 of the tank cover, and then the heat-conducting medium is introduced into the heat-conducting coil 101 to quickly heat up the sterilizing tank 1 to sterilize the fermented juice. After the sterilization is completed, the water pump 4 between the sterilizing tank 1 and the cooling tank 2 is started to allow the juice to enter the cooling tank 2 along the water pipe, and then the cooling medium is added to the cooling coil 201 outside the cooling tank 2 to quickly cool the fermented juice in the cooling tank 2, thereby not affecting the taste of the fermented juice; then, the water pump 4 between the cooling tank 2 and the collecting bin 301 is started to allow the fermented juice that has been cooled in the cooling tank 2 to be sent to the collecting bin 301 along the water pipe. At this time, the collecting bin 301 is connected to the bottom inlet The liquid inlet 302 enters the lower layer of the S-shaped liquid guiding channel of the sterilization box 3. When the liquid level rises, the juice will flow along the lower guide plate 304 and the upper guide plate 305 in an S-shaped trajectory, and the fermented juice will be sterilized by ultraviolet light by the ultraviolet lamps 303 distributed in a rectangular array when flowing in the S-shaped liquid guiding channel, so that the fermented juice can be fully and continuously sterilized by ultraviolet light. When the liquid level rises to the liquid outlet valve 306 on one side of the upper guide plate 305, the fermented juice will be discharged along the liquid outlet valve 306. When it is necessary to empty the fermented juice inside the sterilization box 3, by opening the discharge valve on the sterilization box 3, the juice on the upper guide plate 305 and the lower guide plate 304 will reflux along the S-shaped liquid guiding channel and be quickly discharged along the discharge valve.

[0022] See also Figure 8-Figure 13 The interior of the driving housing 5 is symmetrically connected to a transmission gear 503 through a bearing, and the upper and lower sides of the transmission gear 503 are meshed with a driving gear 504 respectively fixed to the stirring shaft 502 and the sleeve 505; the outer side of the stirring shaft 502 is also fixed with a large bevel gear 506 meshing with the small bevel gear 802; The extrusion shaft 801 is composed of cylindrical shafts at both ends and a rectangular strip in the middle. A U-shaped cavity abutting against the rectangular strip is provided on the plane of one side of the defoaming roller 805, and a spring 803 is connected between the two sides of the rectangular strip and the U-shaped cavity. Blocks are provided on both sides of the rectangular strip of the extrusion shaft 801, and a snap-fitting groove that slidably cooperates with the block is provided on the surface of the U-shaped cavity of the defoaming roller 805, so that the rectangular strip of the extrusion shaft 801 has a guiding and anti-biasing effect when it is slidably connected to the defoaming roller 805. An inner cavity 806 is provided on the edge of the plane on one side of the defoaming roller 805, and an elastic foam absorption tube 807 and a pressure plate 804 are connected to the interior of the inner cavity 806. The pin end of the pressure plate 804 is connected to the rectangular strip of the extrusion shaft 801, and a guide groove 808 is provided on the outer side of the defoaming roller 805 near the arch strip 704. The elastic foam absorption tube 807 is made of silicone or rubber to ensure that the elastic foam absorption tube 807 has the function of elastic deformation and reset. The defoaming roller 805 is a semi-cylindrical structure, and the arc angle of the guide groove 808 is less than 180°. Therefore, when the defoaming roller 805 is close to the outer edge of the guide groove 808 and squeezed with the bulge on the inner wall of the arch strip 704, the U-shaped cavity of the defoaming roller 805 will slide with the extrusion shaft 801 and compress the spring 803.

[0023] During the specific implementation, the stirring shaft 502 is driven to rotate forward by starting the motor 501, so that the stirring shaft 502 stirs the fermented juice in the sterilizing tank 1, thereby driving the fermented juice in the sterilizing tank 1 to heat up quickly and preventing the fermented juice from precipitating, so that the driving gear 504 on the stirring shaft 502 drives the driving gear 504 on the sleeve 505 to mesh and transmit through the transmission gear 503 in the driving shell 5, so that the sleeve 505 and the stirring shaft 502 produce a coaxial reverse effect; when the sleeve 505 reverses inside the top cover 6, the sleeve 505 will drive the inner cylinder in the middle of the bottom shell 7 to reverse, so that the bottom shell 7 rotates in the opposite direction above the liquid level; When the bottom shell 7 is reversed, the small conical toothed disk 802 at one end of the extrusion shaft 801 is driven to mesh with the large conical toothed disk 506 on the stirring shaft 502, so that the extrusion shaft 801 rotates between the two defoaming rollers 805. Since the extrusion shaft 801 slides with the engaging grooves of the defoaming rollers 805 through the card block, the defoaming rollers 805 can be driven to rotate. Since the connection between the two adjacent defoaming rollers 805 and the extrusion shaft 801 is achieved by squeezing and pushing with the spring 803, the edge of one side of the defoaming rollers 805 close to the elastic foam suction tube 807 is misaligned with the edge of the other defoaming roller 805, and the opening of the elastic foam suction tube 807 is exposed. When the stirring shaft 502 rotates forward to stir the fermented juice, the sleeve 505 will drive the bottom shell 7 to reverse, so the defoaming roller 805 will also produce a circular rotation in the opposite direction to the juice stirring rotation direction, and at the same time, the large bevel gear disk 506 that rotates forward will drive the extrusion shaft 801 to reverse, so that the defoaming roller 805 will also rotate around the center line of the extrusion shaft 801. At this time, the two misplaced defoaming rollers 805 can drive the elastic foam suction tube 807 to scrape the scum and foam on the upper layer of the fermented juice surface during the circular rotation and self-rotation; when one of the defoaming rollers 805 is close to the outer edge of the elastic foam suction tube 807 and squeezes against the protrusion on the inner wall of the round arch strip 704, the inner wall of the round arch strip 704 The protrusions of the wall will push the defoaming roller 805, so that the U-shaped cavity of the defoaming roller 805 will slide with the rectangular strip of the extrusion shaft 801, and at this time the pressing plate 804 will compress the elastic foam suction tube 807 in the inner cavity 806, so that the elastic foam suction tube 807 will spray the scum and foam collected inside from the opening when compressed; since the bottom shell 7 is a conical surface structure, the defoaming roller 805 in the through hole 702 is in an inclined setting, and when the fermented juice is stirred, the scum and foam on the upper layer of the liquid level will be away from the rotation center due to centrifugal rotation. At this time, the inclined defoaming roller 805 will not absorb too much juice liquid when the elastic foam suction tube 807 rotates to scrape the scum and foam; When the defoaming roller 805 rotates to the outer guide groove 808 and docks with the protrusion on the inner wall of the arch strip 704, the two defoaming rollers 805 can be driven to be offset from each other through the resetting of the spring 803, so that the defoaming roller 805 with the elastic foam suction tube 807 opening facing downward can scrape the scum and foam.

[0024] See also Figure 1 , Figure 2 , Figure 4-Figure 8 as well as Figure 10-13 A rotating paddle 810 is connected between the two circular arch bars 704. The paddles of the rotating paddle 810 are made of silicone material, so that the paddles of the rotating paddle 810 have the effect of elastic deformation and reset. A synchronous component 809 is connected between the end of the rotating paddle 810 extending into the waterproof cover 701 and the extrusion shaft 801. The synchronous component 809 adopts a synchronous belt and synchronous wheel transmission or a chain and sprocket transmission, and the rotating paddle 810 and the extrusion shaft 801 are driven to rotate in the same direction through the synchronous component 809; a transmission installed with the bottom shell 7 is provided between two adjacent through holes 702. A collecting plate 9 is provided, one side edge of the collecting plate 9 is provided with a convex strip for scraping off the scum and foam on the surface of the rotating paddle 810, the other side of the collecting plate 9 is provided with a baffle for blocking the scum and foam, an arc-shaped slide 703 is provided on the outer side of the bottom shell 7, a slag suction channel 901 is connected between the outer side of the collecting plate 9 and the slide 703, a suction nozzle 902 with an opening toward the slag suction channel 901 is provided inside the slide 703, a slag discharge pipe penetrating the top cover 6 and the tank cover is fixed on the top of the suction nozzle 902, and a suction pump 903 connected to the slag discharge pipe is installed on the outer side of the tank cover.

[0025] In specific implementation, when the pressing plate 804 compresses the elastic foam suction tube 807, the scum and foam containing a small amount of juice ejected from the opening of the elastic foam suction tube 807 will be ejected along the outer edge of another foam removal roller 805, and at the same time, the extrusion shaft 801 drives the rotating paddle 810 to rotate through the synchronous component 809, so that the rotating paddle 810 will rotate and send the ejected scum and foam into the collection tray 9. Since the collection tray 9 is provided with a convex strip near the edge of the rotating paddle 810 for scraping off the scum and foam on the surface of the rotating paddle 810, there will be no excessive scum and foam left after the rotating paddle 810 rotates one circle. When the scum and foam enter the collection tray 9, the rotating bottom shell 7 and the collection tray 9 are rotated. The disk 9 can centrifugally swing the scum and foam, and the baffle on one side of the collecting disk 9 can block the swinging scum and foam. At the same time, the air inside the suction nozzle 902 can be sucked by starting the suction pump 903. When the bottom shell 7 rotates, it will drive the outer slide 703 and the suction nozzle 902 to slide relative to each other, so that the suction nozzle 902 is intermittently aligned with the scum suction channel 901 at different positions, so that the scum and foam collected in the collecting disk 9 can be removed by the suction nozzle 902 and the scum suction channel 901. When it is necessary to clean the inside of the sterilization tank 1, the defoaming mechanism 8 and the collecting disk 9 can be cleaned and maintained by opening the tank cover and separating the top cover 6 and the bottom shell 7.

[0026] To summarize, the fermented juice is introduced into the sterilization tank 1 for high-temperature sterilization. During stirring and sterilization, the scum and foam in the fermented juice are scraped off by the defoaming mechanism 8. After the sterilization is completed, the water pump 4 between the sterilization tank 1 and the cooling tank 2 is started to allow the juice to enter the cooling tank 2 for rapid cooling, thereby not affecting the taste of the fermented juice. Subsequently, the fermented juice that has been cooled is introduced into the sterilization box 3 for ultraviolet disinfection, so that the equipment can fully automatically sterilize the fermented juice during operation.
