Description

Technical Field

[0001] The invention relates to the technical field of sterilization equipment, in particular to a full-automatic sterilization equipment for fermented fruit juice. Background Art

[0002] Fermented juice refers to juice made by fermenting crushed fruit pulp. By fermenting the pulp, fermented juice maximizes the nutritional value of the fruit and produces a large number of nutrients such as amino acids and short-chain fatty acids during the fermentation process. Fermentation also produces a large number of probiotic metabolites, which improve the intestinal environment and enhance the body's immune system. After fermentation, fermented juice undergoes filtration and sterilization to remove excess bacteria and metabolites and preserve nutrients.

[0003] According to Chinese patent publication number CN221265116U, a fruit juice production sterilization device is disclosed. By arranging a sterilization tank, a storage tank, a first heat pipe, a second heat pipe, a connecting pipe, an inner heat pipe, an inner pipe, and an outer pipe, the sterilization tank is heated both inside and outside, rapidly increasing the temperature of the sterilization tank, shortening the time required for sterilization heating and improving sterilization efficiency. Furthermore, after sterilization, the residual heat is used to preheat the fruit juice, shortening the time required for sterilization heating and further improving sterilization efficiency.

[0004] The above technical solution uses a stirring component to stir the juice so that the juice is stirred and heated evenly, further reducing the time used for sterilization. When stirring the juice, it is easy to cause scum and foam to form on the upper surface of the high-temperature sterilized juice, which will affect the taste of the juice after sterilization.

[0018] Compared with the prior art, the present invention has the following beneficial effects: the fully automatic sterilizing equipment for fermented juice performs high-temperature sterilization in a sterilizing tank, then rapidly cools down the temperature in a cooling tank, and finally sterilizes with ultraviolet light in a sterilizing box; a defoaming mechanism is provided in the sterilizing tank to scrape scum and foam from the upper layer of the liquid surface of the fermented juice; and at the same time, a suction nozzle is used to intermittently suck out the scum and foam collected in a collection tray, so that the scum and foam that affect the drinking taste of the fermented juice can be quickly removed when the fermented juice is stirred during the high-temperature sterilization, thereby ensuring that the fermented juice has an improved drinking taste after the fully automatic sterilization.

[0019] 1. This fully automatic sterilization equipment for fermented juice performs high-temperature sterilization in a sterilization tank. After sterilization, the juice is sent to a cooling tank for rapid cooling. The cooled fermented juice is then introduced into a collection bin, allowing the fermented juice to enter the S-shaped liquid guide channel of the sterilization box through a liquid inlet for full and continuous ultraviolet disinfection. When the fermented juice in the sterilization box needs to be drained, the drain valve on the sterilization box is opened, allowing the juice on the upper and lower drain plates to flow back along the S-shaped liquid guide channel and be quickly discharged along the drain valve. At the same time, the juice can be repeatedly disinfected by ultraviolet light during the reflux.

[0020] 2. The fully automatic sterilizing equipment for fermented juice uses the coaxial reversing effect of the sleeve and the stirring shaft to make the bottom shell rotate in the opposite direction above the liquid level. When the stirring shaft rotates the fermented juice in the forward direction, the defoaming roller will produce a circular rotation in the opposite direction to the juice stirring rotation. At the same time, the forward-rotating large bevel gear disk drives the extrusion shaft to reverse, so that the defoaming roller will also rotate around the center line of the extrusion shaft. At this time, the two staggered defoaming rollers can drive the elastic foam suction cylinder to scrape the scum and foam on the upper surface of the fermented juice during the circumferential rotation and self-rotation, and use the pressure plate to compress the elastic foam suction cylinder to spray out the scum and foam. At the same time, the sprayed scum and foam are rotated and sent into the collection tray by the rotating paddle. Then, the air inside the suction nozzle is sucked by the suction pump, so that the suction nozzle is intermittently aligned with the scum suction channels at different positions, so that the suction nozzle and the scum suction channel can cooperate to remove the scum and foam collected in the collection tray, ensuring that the fermented juice can quickly remove scum and foam during stirring and sterilization, thereby improving the drinking taste of the fermented juice.

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figures 1-8 The present invention provides a technical solution: a fully automatic sterilization device for fermented fruit juice, comprising a sterilization tank 1, a cooling tank 2, and a sterilization box 3. The cooling tank 2 and the sterilization box 3 are arranged outside the sterilization tank 1. A heat conduction coil 101 for circulating a heat conduction medium is installed in the interlayer of the sterilization tank 1. A cooling coil 201 for circulating a cooling medium is surrounded by the circumferential side surface of the cooling tank 2.

[0037] A flow collecting chamber 301 is installed on one side of the interior of the sterilization box 3. A lower drain plate 304 and an upper drain plate 305 are sequentially arranged inside the sterilization box 3 from bottom to top. Ultraviolet lamps 303 are distributed in a rectangular array inside the sterilization box 3 and penetrate both the lower drain plate 304 and the upper drain plate 305.

[0038] A tank cover is installed on the top of the sterilizing tank 1, and a motor 501 is installed in the center of the top of the tank cover, and a feeding tube 103 is docked at the top edge of the tank cover. A driving shell 5 docked with the tank cover is provided below the motor 501, and a stirring shaft 502 that passes through the tank cover and the driving shell 5 is fixed to the output end of the motor 501. A sleeve 505 movably connected to the driving shell 5 is provided on the outer side of the stirring shaft 502. A top cover 6 movably sleeved with the sleeve 505 is installed on the top surface of the inner wall of the tank cover. A bottom shell 7 with a conical bottom surface is rotatably connected to the bottom of the top cover 6. The outer edge of the bottom of the top cover 6 is fixed with a sleeve that abuts against the outer edge of the top of the bottom shell 7. The side of the sterilizing tank 1 is equipped with a high-temperature resistant photoelectric liquid level sensor 102. When the fermented juice is added to 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 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 during rotation. At the same time, the photoelectric liquid level sensor 102 adopts a photoelectric liquid level switch of the brand Super Hua Shijing and model LJ-1 / 2NPT, so that the photoelectric liquid level sensor 102 can detect the liquid level of the fermented juice sterilized at an instantaneous high temperature;

[0039] An inner cylinder mounted on the lower end of the sleeve 505 is fixed to the middle part of the bottom shell 7, and a water-proof cover 701 is fixed to the outside 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, and a defoaming mechanism 8 for rotating and scraping scum from the liquid surface is provided inside the through hole 702. Circular arch strips 704 are fixed to both ends of the upper side of the bottom shell 7 near the through hole 702, and the inner wall of the circular arch strip 704 is integrally formed with a protrusion. The defoaming mechanism 8 includes an extrusion shaft 801 that rotates with both 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 that extends through the inner cylinder, and defoaming rollers 805 are slidably connected to both sides of the extrusion shaft 801.

[0040] 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 provided on one side of the bottom of the sterilizing box 3, and the upper and lower sides of the sterilizing box 3 away from the collecting bin 301 are respectively connected to the liquid outlet valve 306 and the discharge valve, 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 guide plate 304 is fixed to the collecting bin 301, and one end of the upper guide 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 guide 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 guide plate 305 close to the collecting bin 301. An S-shaped liquid guide channel is formed inside the sterilization box 3 through the lower guide plate 304 and the upper guide plate 305.

[0041] During specific implementation, the fermented juice is introduced into the sterilizing tank 1 from the feeding pipe 103 of the tank cover, and then a heat-conducting medium is introduced into the heat-conducting coil 101 to quickly heat 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; subsequently, the water pump 4 between the cooling tank 2 and the collecting bin 301 is started to allow the fermented juice that has completed cooling 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 inlet at the bottom. The liquid inlet 302 enters the lower position of the S-shaped liquid guide 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 guide 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 the side of the upper guide plate 305, the fermented juice will be discharged along the liquid outlet valve 306. When the fermented juice inside the sterilization box 3 needs to be emptied, the discharge valve on the sterilization box 3 is opened to make the juice on the upper guide plate 305 and the lower guide plate 304 flow back along the S-shaped liquid guide channel and be quickly discharged along the discharge valve.

[0042] See also Figures 8-13 The interior of the drive housing 5 is symmetrically connected to a transmission gear 503 through a bearing. The upper and lower sides of the transmission gear 503 are engaged with a driving gear 504 fixed to the stirring shaft 502 and the sleeve 505 respectively; the outer side of the stirring shaft 502 is also fixed with a large bevel gear 506 engaged with the small bevel gear 802;

[0043] The extrusion shaft 801 is composed of cylindrical shafts at both ends and a rectangular strip in the middle. A U-shaped cavity is provided on the plane of one side of the defoaming roller 805, which abuts against the rectangular strip. 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 is provided on the surface of the U-shaped cavity of the defoaming roller 805, which slides with the block. This provides a guiding and anti-deflection effect when the rectangular strip of the extrusion shaft 801 is slidably connected to the defoaming roller 805.

[0044] An inner cavity 806 is provided on the edge of the plane on one side of the defoaming roller 805, and the interior of the inner cavity 806 is connected to an elastic foam suction tube 807 and a pressure plate 804. The pin end of the pressure plate 804 is connected to the rectangular bar of the extrusion shaft 801, and the defoaming roller 805 is provided with a guide groove 808 near the outside of the circular arch strip 704. The elastic foam suction tube 807 is made of silicone or rubber to ensure that the elastic foam suction 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 against the bulge on the inner wall of the circular arch strip 704, the U-shaped cavity of the defoaming roller 805 will slide with the extrusion shaft 801 and compress the spring 803.

[0045] During specific implementation, the motor 501 is started to drive the stirring shaft 502 to rotate forward, so that the stirring shaft 502 stirs the fermented juice in the sterilizing tank 1, thereby causing the fermented juice in the sterilizing tank 1 to heat up quickly and prevent the fermented juice from precipitating. The driving gear 504 on the stirring shaft 502 drives the driving gear 504 on the sleeve 505 to engage with the transmission gear 503 in the drive housing 5, so that the sleeve 505 and the stirring shaft 502 produce a coaxial reverse effect; when the sleeve 505 is reversed 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;

[0046] When the bottom shell 7 is reversed, the small conical toothed disk 802 at one end of the extrusion shaft 801 is driven to engage 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 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.

[0047] 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 staggered defoaming rollers 805 can drive the elastic foam suction cylinder 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 approaches the outer edge of the elastic foam suction cylinder 807 and squeezes against the protrusion on the inner wall of the arch bar 704, the inner wall of the arch bar 704 The protrusions on the wall will squeeze and push the defoaming roller 805, so that the U-shaped cavity of the defoaming roller 805 will slide against the rectangular strip of the extrusion shaft 801. At this time, the pressure plate 804 will compress the elastic foam suction cylinder 807 in the inner cavity 806, so that the elastic foam suction cylinder 807 will spray the scum and foam collected inside from the opening during compression. Since the bottom shell 7 has a conical surface structure, the defoaming roller 805 in the through hole 702 is arranged at an angle. When the fermented juice is stirred, the scum and foam on the upper layer of the liquid level will move 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 cylinder 807 rotates to scrape the scum and foam.

[0048] 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 spring 803 is reset to drive the two defoaming rollers 805 to be offset from each other, making it easier for the defoaming roller 805 with the elastic foam suction tube 807 opening facing downward to scrape off the scum and foam.

[0049] 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 blades of the rotating paddle 810 are made of silicone material, so that the blades 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 interior of the water-proof 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 mounting hole 702 is provided between the two adjacent through holes 702. The collecting tray 9 has a convex strip on one side edge for scraping off scum and foam on the surface of the rotating paddle 810, and a baffle for blocking scum and foam is provided on the other side of the collecting tray 9. An arc-shaped slide 703 is provided on the outside of the bottom shell 7, and a slag suction channel 901 is connected between the outside of the collecting tray 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 that passes through 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 outside of the tank cover.

[0050] In specific implementation, when the pressure plate 804 compresses the elastic foam suction cylinder 807, the scum and foam containing a small amount of juice ejected from the opening of the elastic foam suction cylinder 807 will be ejected along the outer edge of the other foam removal roller 805. At the same time, the extrusion shaft 801 drives the rotating paddle 810 to rotate through the synchronization 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 disc 9 can centrifugally swing the scum and foam, and the baffle on one side of the collecting disc 9 blocks the swinging scum and foam. At the same time, the air inside the suction nozzle 902 is sucked by starting the suction pump 903. When the bottom shell 7 rotates, it drives 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 disc 9 can be sucked away by the suction nozzle 902 and the scum suction channel 901. When it is necessary to clean the interior of the sterilizing tank 1, the defoaming mechanism 8 and the collecting disc 9 can be cleaned and maintained by opening the tank cover and separating the top cover 6 and the bottom shell 7.

[0051] To sum up, 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 and cool down quickly, so as not to affect the taste of the fermented juice. The fermented juice that has been cooled is then introduced into the sterilization box 3 for ultraviolet disinfection, so that the equipment can fully automatically sterilize the fermented juice during operation. The contents not described in detail in this specification belong to the existing technology well known to professional and technical personnel in this field.
