Description

Technical Field

[0001] The invention relates to the technical field of cleaning, and in particular to a cleaning device for producing paste yeast. Background Art

[0002] Paste yeast usually refers to yeast paste, which is a brown to brown soluble paste product with a special natural fragrance. It is easily soluble in water, and the aqueous solution is light yellow to light brown, and the reaction is weakly acidic. Yeast paste is rich in proteins, amino acids, peptides, water-soluble vitamins, yeast polysaccharides, yeast nucleic acids, as well as nucleotides, organic acids, minerals and other substances. It is the main raw material in biological culture medium and fermentation industry, which can greatly improve the production rate of strains and the yield of fermentation products.

[0003] In the related technology, the industrial preparation of paste yeast requires two processes: cultivation and fermentation. The cultivation process requires the yeast strain to be inoculated into the culture medium and cultured for a period of time to ensure that it is in an active state. The fermentation process is to inoculate the cultured yeast strain into the fermentation tank, add an appropriate amount of culture medium, and control the appropriate temperature, pH value and oxygen supply to ensure that the yeast strain can fully grow and reproduce. After the fermentation is completed, the fermentation tank needs to be cleaned to remove impurities in it so that it can be fermented again later.

[0004] A Chinese patent with authorization announcement number CN114631563B discloses a fully automatic yogurt fermentation production system and method, which includes a fermentation tank, wherein a feed port and a discharge port are respectively arranged on the upper and lower sides of the fermentation tank, a stirring rod is rotatably connected inside the fermentation tank, and the stirring rod is provided with evenly distributed stirring blades. The fermentation tank is also provided with a driving component for driving the stirring rod to rotate, a scraper ring is arranged inside the fermentation tank, and a scraper mechanism is arranged on the scraper ring. The scraper mechanism includes a first scraping component for scraping off residues on the outside of the scraper ring and a second scraping component arranged on the first scraping component, and a displacement component for driving the scraper ring to move up and down is arranged in the stirring rod.

[0005] The above patent cleans the inner wall of the fermentation tank by means of a scraping ring, and scrapes off the residues attached to the inner wall of the fermentation tank.

[0006] In the related art, in order to thoroughly clean the fermentation tank, it is usually necessary to soak the inner wall of the fermentation tank with a detergent first. A fermentation tank with a smaller volume can be directly filled with the detergent, but for a fermentation tank with a larger volume, it is still necessary to fill it with the detergent for the cleaning effect, and since the detergent cannot be reused after contacting with impurities, the cleaning cost is higher. Summary of the invention

[0007] The present invention provides a cleaning device for producing paste yeast, aiming to solve the problem of high cleaning cost caused by filling a fermentation tank with cleaning agent in the related art.

[0008] The cleaning device for producing paste yeast of the present invention comprises: a fermentation barrel, a stirring component, and a soaking component;

[0009] The stirring assembly comprises a rotating shaft and blades, the rotating shaft is rotatably fitted in the fermentation barrel, a sleeve is slidably fitted on the rotating shaft, a lifting mechanism is provided on the fermentation barrel, the lifting mechanism is used to drive the sleeve to move up and down, the sleeve is provided with a plurality of extension arms spaced along its circumference, and each extension arm is provided with a blade;

[0010] The soaking assembly includes an upper cover plate, a connecting wall, a lower bottom plate and a driving ring. The upper cover plate is slidably matched with the rotating shaft. The lower bottom plate is arranged below the upper cover plate. The connecting wall is located between the upper cover plate and the lower bottom plate. The lower bottom plate and the upper cover plate are both sealed and fitted with the fermentation barrel. A cleaning chamber is formed between the upper cover plate, the connecting wall and the lower bottom plate. A driving ring is provided on the extension arm, and a first hook is provided on the driving ring. A second hook is provided at the bottom end of the lower bottom plate, and the first hook can be snapped together with the second hook.

[0011] Beneficial effect: When cleaning the fermentation barrel, you only need to fill the cleaning chamber with a small amount of detergent, rotate the shaft, and drive the lifting mechanism to move upward at the same time, so that the first hook and the second hook are engaged, and then the lifting mechanism slowly drives the sleeve to move downward, and the soaking component and the sleeve move downward synchronously. During the downward movement of the soaking component, the detergent in the cleaning chamber soaks the side wall of the fermentation barrel from top to bottom.

[0012] Preferably, the outer wall of the driving ring is in contact with the inner wall of the fermentation barrel, and the driving ring and the fermentation barrel are in sliding fit.

[0013] The effect is that before the cleaning chamber soaks the side wall of the fermentation barrel, the driving ring can scrape the inner wall of the fermentation barrel, thereby scraping off the paste yeast attached to the inner wall of the fermentation barrel to prevent waste.

[0014] Preferably, the bottom of the fermentation barrel is a funnel-shaped structure, the bottom end of the barrel bottom is provided with a discharge port, and a valve is provided at the discharge port.

[0016] The effect is that when the blade moves downward to the bottom of the fermentation barrel, the bottom end of the movable connecting rod stops at the bottom of the fermentation barrel. At this time, the blade continues to move downward so that the bottom end of the movable connecting rod moves along the bottom of the fermentation barrel until the movable connecting rod fits with the bottom of the fermentation barrel, and the rubber sheet is retracted and folded in half. At this time, the rotating shaft rotates so that the rubber sheet can scrape off the paste yeast attached to the bottom of the fermentation barrel to prevent waste.

[0017] Preferably, a first scraper and a second scraper are further provided at the bottom of the extension arm, the first scraper is fixedly connected to the extension arm, the second scraper is connected to the first scraper via a first elastic member, a first gear is provided on the movable connecting rod, and a second gear is provided on the extension arm, the first gear can engage with the second gear, and the first scraper and the second scraper can fit with the rubber sheet.

[0018] The effect is that the paste yeast scraped off the bottom of the fermentation barrel is collected in the gap formed by the folded rubber sheet, and the shaft sleeve continues to move downward, so that the telescopic connecting rod stops at the bottom of the fermentation barrel, the telescopic connecting rod contracts, and the first gear moves upward along the second gear, thereby driving the movable connecting rod to rotate upward. When the movable connecting rod passes through the gap between the first splint and the second splint, the first splint and the second splint can squeeze the folded rubber sheet to squeeze out the paste yeast in the gap of the rubber sheet, and the squeezed paste yeast falls at the discharge port under the action of gravity.

[0019] Preferably, a connecting hole is provided on the lower bottom plate, and a sealing plate is slidably fitted on the lower bottom plate. A second elastic member is provided on the sealing plate, and the second elastic member abuts against the side wall of the fermentation barrel. The sealing plate can seal the connecting hole, and the movable connecting rod can abut against the sealing plate and push the sealing plate to move.

[0020] The effect is that the movable connecting rod continues to move upward, thereby stopping with the sealing plate and pushing the sealing plate to move, so that the connecting hole is exposed, and the cleaning agent in the cleaning chamber can flow into the fermentation barrel through the connecting hole and gather at the bottom of the fermentation barrel, thereby soaking the bottom of the fermentation barrel.

[0021] Preferably, cleaning pads are provided on the outer side walls of the upper cover plate and the lower base plate, and the cleaning pads are in contact with the inner wall of the fermentation barrel.

[0022] Preferably, a liquid inlet is provided on the upper cover plate, and the liquid inlet is communicated with the cleaning cavity.

[0023] By adopting the above technical solution, the beneficial effects of the present invention are:

[0024] According to the cleaning device for the production of paste yeast of the present invention, when cleaning the fermentation barrel, it is only necessary to fill the cleaning chamber with a small amount of cleaning agent, rotate the rotating shaft, and drive the lifting mechanism to move upward at the same time, so that the first hook and the second hook are engaged with each other, and then the lifting mechanism slowly drives the sleeve to move downward, and the soaking component and the sleeve move downward synchronously. During the downward movement of the soaking component, the cleaning agent in the cleaning chamber soaks the side wall of the fermentation barrel from top to bottom, and the fermentation barrel can be soaked without filling the fermentation barrel, thereby saving cleaning agent and reducing cleaning costs.

[0036] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0037] like Figures 1 to 9 As shown, the cleaning device for producing paste yeast of the present invention comprises: a fermentation barrel 1, a stirring component and a soaking component.

[0038] Specifically, Figure 1 and Figure 2 As shown, the top of the fermentation barrel 1 is provided with an end cover 2, and the end cover 2 is provided with a feed port 17, and the end cover 2 is used to close the fermentation barrel 1. The side wall of the fermentation barrel 1 is provided with a feed port 17, and the bottom of the fermentation barrel 1 is a funnel structure, and the lowest point of the funnel structure is provided with a discharge port 18, and a valve is provided at the discharge port 18.

[0039] like Figures 2 to 5As shown, the stirring assembly includes a rotating shaft 3 and blades. The rotating shaft 3 is rotatably matched in the fermentation barrel 1. The rotating shaft 3 is coaxially distributed with the fermentation barrel 1. The end cover 2 is provided with a driving motor 4. The output end of the driving motor 4 passes through the end cover 2 and is fixedly connected to the rotating shaft 3. The driving motor 4 is used to drive the rotating shaft 3 to rotate. A sleeve 5 is slidably matched on the rotating shaft 3. A matching key is provided on the rotating shaft 3. A matching groove is provided on the sleeve 5. The matching key and the matching groove are slidably matched. A lifting mechanism 6 is also provided in the fermentation barrel 1. The lifting mechanism 6 is a hydraulic cylinder. The top end of the lifting mechanism 6 is fixedly connected to the end cover 2. The output end of the lifting mechanism 6 is fixedly connected to a limiting sleeve. The limiting sleeve is rotatably matched with the sleeve 5. The lifting mechanism 6 drives the limiting sleeve to move up and down, thereby driving the sleeve 5 to move up and down relative to the rotating shaft 3. A plurality of extension arms 7 are provided on the side wall of the sleeve 5 at evenly spaced intervals along its circumference. The blades include a telescopic link 81, a fixed link 82, a movable link 83 and a rubber sheet 84. The telescopic link 81 is an elastic telescopic rod. The top end of the telescopic link 81 is fixedly connected to the outer end of the extension arm 7, and the bottom end of the telescopic link 81 is fixedly connected to the fixed link 82. The fixed link 82 is located below the extension arm 7 and is distributed parallel to the extension arm 7. The movable link 83 is rotationally matched with the bottom end of the telescopic link 81 through a torsion spring, and an angle can be formed between the movable link 83 and the fixed link 82. The rubber sheet 84 is located between the fixed link 82 and the movable link 83, and the two sides of the rubber sheet 84 are fixedly connected to the fixed link 82 and the movable link 83 respectively. The movable connecting rod 83 rotates downward under the action of the torsion spring and tightens the rubber sheet 84, so that the rubber sheet 84 forms a fan-shaped structure. When the rotating shaft 3 drives the extension arm 7 to rotate through the shaft sleeve 5, the blades and the extension arm 7 rotate synchronously, thereby being able to stir the material in the fermentation barrel 1.

[0040] like Figures 2 to 4 , Figure 6 As shown, the soaking assembly includes an upper cover plate 91, a connecting wall 92, a lower bottom plate 93 and a driving ring 10. The upper cover plate 91 is sleeved on the rotating shaft 3 and is located above the shaft sleeve 5. The upper cover plate 91 and the rotating shaft 3 are slidably matched. The upper cover plate 91 is provided with a liquid inlet 19. The connecting wall 92 is an annular plate, and its top end is rotatably matched with the upper cover plate 91. The bottom end of the connecting wall 92 is provided with a lower bottom plate 93. The lower bottom plate 93 is parallel to the upper cover plate 91 and is spaced apart. The upper cover plate 91 and the lower bottom plate 93 are evenly attached to the side wall of the fermentation barrel 1. The outer side walls of the upper cover plate 91 and the lower bottom plate 93 are both provided with cleaning pads. The cleaning pads are rubber pads. The cleaning pads are frictionally matched with the side wall of the fermentation barrel 1. A cleaning cavity can be formed between the upper cover plate 91, the connecting wall 92 and the lower bottom plate 93. The cleaning cavity is annular. The outer end of the extension arm 7 is fixedly connected to a driving ring 10, the outer side wall of the driving ring 10 abuts against and slides with the fermentation barrel 1, a first hook 931 is provided on the driving ring 10, and a second hook 101 is provided at the bottom end of the lower bottom plate 93. The first hook 931 and the second hook 101 can be buckled and matched.

[0041] The rotating shaft 3 drives the sleeve 5 to rotate counterclockwise, and at the same time the lifting mechanism 6 drives the sleeve 5 to move upward, so that the first hook 931 can be engaged with the second hook 101. At this time, the lifting mechanism 6 drives the sleeve 5 to move downward again, and the driving ring 10 moves downward synchronously with the sleeve 5, and pulls the soaking assembly downward, so that the soaking assembly overcomes the friction between the upper cover plate 91 and the side wall of the fermentation barrel 1 and moves downward.

[0042] like Figure 2 , Figure 4 and Figure 7 As shown, the end of the movable link 83 close to the side wall of the fermentation barrel 1 is also provided with a first gear 11, and the outer end of the extension arm 7 is provided with a second gear 12. The bottom of the extension arm 7 is also provided with a first scraper 13 and a second scraper 14, the first scraper 13 is fixedly connected to the bottom end of the extension arm 7, the first scraper 13 is parallel to the extension arm 7, the second scraper 14 is parallel to the first scraper 13 and is spaced apart in the horizontal direction, the second scraper 14 is elastically connected to the first scraper 13 through a first elastic member, and there is a gap between the first scraper 13 and the second scraper 14. The fixed link 82 is located in the gap between the first scraper 13 and the second scraper 14.

[0043] When the blade moves downward to the bottom of the fermentation barrel 1, the bottom end of the movable link 83 abuts against the bottom of the fermentation barrel 1 and moves along the bottom of the barrel, so that the movable link 83 rotates, and the angle between the movable link 83 and the fixed link 82 decreases, thereby retracting the rubber sheet 84, and the rubber sheet 84 is folded in half and attached to the bottom of the fermentation barrel 1. At this time, the rotation of the rotating shaft 3 causes the rubber sheet 84 to scrape off the residual material at the bottom of the fermentation barrel 1, and the material is collected in the gap formed by the folded rubber sheet 84. The lifting mechanism 6 continues to drive the shaft sleeve 5 to move downward, so that the bottom end of the telescopic link 81 abuts against the bottom surface of the fermentation barrel 1, and the telescopic link 81 contracts, so that the first gear 11 gradually approaches the second gear 11. Second gear 12, when the first gear 11 is meshed with the second gear 12, the telescopic link 81 contracts so that the first gear 11 moves upward along the second gear 12, and the second gear 12 drives the first gear 11 to rotate, and the movable link 83 rotates synchronously with the first gear 11, and the movable link 83 rotates upward and passes through the gap between the first scraper 13 and the second scraper 14. After the movable link 83 passes through the gap between the first scraper 13 and the second scraper 14, the first scraper 13 and the second scraper 14 can squeeze the folded rubber sheet 84 under the action of the first elastic member, and squeeze out the material in the gap of the rubber sheet 84, and the extruded material falls at the discharge port 18 under the action of gravity.

[0044] like Figure 6 and Fig. 9As shown, a connecting hole 932 is provided on the lower bottom plate 93, and a sealing plate 15 is provided in the cleaning chamber. The sealing plate 15 and the lower bottom plate 93 are slidably matched. A second elastic member 16 is provided on the side wall of the sealing plate 15. The second elastic member 16 is an elastic column. One end of the second elastic member 16 is fixedly connected to the sealing plate 15, and the other end thereof is stopped against the side wall of the fermentation barrel 1. The sealing plate 15 passes through the connecting wall 92 and extends into the fermentation barrel 1. The movable connecting rod 83 can stop against the sealing plate 15. The sealing plate 15 is used to close the connecting hole 932.

[0045] When the sleeve 5 moves downward to the lowest point, the telescopic connecting rod 81 also contracts to the limit. At this time, the movable connecting rod 83 stops at the sealing plate 15 and pushes the sealing plate 15 to move outward, thereby exposing the connecting hole 932. At this time, the cleaning chamber can be connected with the inside of the fermentation barrel 1 through the connecting hole 932.

[0046] According to the cleaning device for the production of paste yeast of the embodiment of the present invention, various raw materials required for the fermentation of paste yeast are added into the fermentation barrel 1 through the feed port 17, and then the shaft sleeve 5 is driven to rotate through the rotating shaft 3, and the shaft sleeve 5 drives the blades to rotate through the extension arm 7, so that the various raw materials are evenly mixed, and then the fermentation operation is started. After the fermentation is completed, the valve of the discharge port 18 is opened to discharge the fermented paste yeast from the discharge port 18. Add detergent into the cleaning chamber from the liquid inlet 19 so that the detergent fills the cleaning chamber, drive the motor 4 to drive the sleeve 5 to rotate counterclockwise, and the lifting mechanism 6 drives the sleeve 5 to move upward until the first hook 931 is engaged with the second hook 101, and then the lifting mechanism 6 drives the sleeve 5 to move downward, and the sleeve 5 moves downward while rotating counterclockwise, and drives the cleaning assembly to move slowly downward, and the driving ring 10 can scrape off the paste yeast attached to the side wall of the fermentation barrel 1 during the downward movement, and the detergent in the cleaning chamber can soak the inner wall of the fermentation tank when it moves downward, and the cleaning pad can scrape the soaked side wall of the fermentation barrel 1 when the upper cover plate 91 moves downward, thereby removing the residue on the side wall of the fermentation barrel 1 and ensuring the cleanliness of the side wall of the fermentation barrel 1.

[0047] When the blade moves downward to the bottom of the fermentation barrel 1, the bottom end of the movable link 83 abuts against the bottom of the fermentation barrel 1 and moves along the bottom of the barrel, so that the movable link 83 rotates, the angle between the movable link 83 and the fixed link 82 decreases, and the movable link 83 gradually fits with the bottom of the fermentation barrel 1, thereby retracting the rubber sheet 84. Figure 8As shown. The rubber sheet 84 is folded in half and attached to the bottom of the fermentation barrel 1. At this time, the rotation of the rotating shaft 3 causes the rubber sheet 84 to scrape off the residual materials at the bottom of the fermentation barrel 1. The materials are collected in the gap formed by the folding of the rubber sheet 84. The lifting mechanism 6 continues to drive the shaft sleeve 5 to move downward, so that the bottom end of the telescopic link 81 stops at the bottom surface of the fermentation barrel 1, and the telescopic link 81 contracts, so that the first gear 11 gradually approaches the second gear 12. When the first gear 11 is meshed with the second gear 12, the telescopic link 81 contracts, so that the first gear 11 moves upward along the second gear 12. The second gear 12 drives the first gear 11 to rotate, and the movable link 83 rotates synchronously with the first gear 11. The movable link 83 rotates upward and passes through the gap between the first scraper 13 and the second scraper 14. After the movable link 83 passes through the gap between the first scraper 13 and the second scraper 14, the first scraper 13 and the second scraper 14 can squeeze the folded rubber sheet 84 under the action of the first elastic member, and squeeze out the materials in the gap of the rubber sheet 84. Fig. 9 As shown, the extruded material falls to the discharge port 18 under the action of gravity. When the movable connecting rod 83 is about to contact the sealing plate 15, the valve at the discharge port 18 is closed.

[0048] When the shaft sleeve 5 moves downward to the lowest point, the telescopic connecting rod 81 is also retracted to the limit. At this time, the movable connecting rod 83 stops at the sealing plate 15 and pushes the sealing plate 15 to move outward, so that the connecting hole 932 is exposed. At this time, the cleaning chamber can be connected with the inside of the fermentation barrel 1 through the connecting hole 932. The cleaning agent in the cleaning chamber flows into the fermentation barrel 1 through the connecting hole 932 and collects at the bottom of the fermentation barrel 1. At this time, the cleaning agent can soak the bottom of the fermentation barrel 1. Then the lifting mechanism 6 drives the shaft sleeve 5 to move upward, and the first gear 11 moves along the second gear 12 to The lower bottom plate 93 and the upper cover plate 91 move upward, and the cleaning pads on the outer walls of the lower bottom plate 93 and the upper cover plate 91 clean the side walls of the fermentation barrel 1 again during the upward movement, thereby further improving the cleaning effect.
