Description

Technical Field

[0001] This invention relates to the field of yeast production and processing equipment technology, specifically to a device and method for debittering and decolorizing yeast waste. Background Technology

[0002] During yeast production, after fermentation, separation, and extraction, some residue remains; this residue is called yeast waste. The main components of yeast waste are proteins, polysaccharides, cell fragments, and some residual culture medium components, with proteins being the primary component.

[0003] Direct discharge of yeast waste can pollute the environment. It is generally treated in the following ways: anaerobic fermentation to decompose the organic matter in the waste and produce usable resources such as biogas; appropriate processing for use as feed for livestock and poultry; and composting to produce organic fertilizer. When used as feed, some proteins in the yeast waste degrade to produce bitter-tasting small-molecule peptides, requiring debittering and decolorization treatment to improve the taste and appearance of the feed products.

[0004] Existing yeast production equipment lacks supporting processing equipment to turn yeast waste into feed. The feed made from yeast waste has a strong bitter taste, which affects the livestock's willingness to eat, and its poor appearance makes it difficult for farmers to accept. Summary of the Invention

[0008] The operating unit includes a drive motor, which is fixedly installed on the outside of the processing box. The drive motor is connected to a rotary shaft, which is coaxially installed with the central axis of the semi-circular groove. A mounting frame is fixedly installed on the rotary shaft, and a connecting crank is installed on the mounting frame. An agitating roller is installed on the connecting crank.

[0009] As a further embodiment of the present invention: side blocking plates are sealed on both sides of the semi-circular groove, and connecting cranks are respectively provided at both ends of the mounting frame. The stirring roller is rotatably installed between the roller and one of the connecting cranks. A bubble holder is provided on the other connecting crank.

[0010] As a further embodiment of the present invention: the bottom of the semicircular groove is uniformly provided with release holes, and a snap-fit ​​bracket is provided at the bottom of the semicircular groove corresponding to the release holes. An arc-shaped sliding groove is provided inside the snap-fit ​​bracket, and a sealing plate is slidably installed inside the arc-shaped sliding groove. The sealing plate is fitted to the bottom of the semicircular groove, and a push-pull cylinder is fixedly installed at the bottom of the semicircular groove. The end of the push-pull cylinder is connected to the sealing plate, and a rubber pad is provided on the side of the sealing plate facing the release holes.

[0011] As a further embodiment of the present invention: the waste residue recycling unit includes a recycling box, and a recycling filter cylinder is provided at the connection between the recycling box and the side wall of the processing box. The recycling filter cylinder is installed across the recycling box and the processing box. A driven pulley is provided at the end of the recycling filter cylinder. A driving pulley is installed at the part of the rotating shaft located outside the processing box. A transmission belt is provided between the driven pulley and the driving pulley. The recycling filter cylinder is provided with a hollow groove, which is closed at one end and open at the other. A sealing ring is installed at the open end of the recycling filter cylinder. The sealing ring is rotatably fitted with the end of the hollow groove. An air pipe is connected to the sealing ring. The air pipe is interconnected with the hollow groove. An air pump is connected to the air pipe. The air pump is fixedly installed on the outer wall of the recycling box.

[0012] As a further embodiment of the present invention: the upper and lower sides of the recycling filter cartridge are installed in contact with the side wall of the processing box, and a baffle plate is provided inside the recycling box, the baffle plate being inserted into the gap of the recycling filter cartridge at an upward angle.

[0013] As a further embodiment of the present invention: the feed pipe is connected to a horizontal pipe at the upper end of the semi-circular groove, the bottom of the horizontal pipe is uniformly provided with leakage holes, the inner diameter of the horizontal pipe is smaller than the inner diameter of the feed pipe, and the two ends of the horizontal pipe are closed.

[0014] As a further embodiment of the present invention: the drain pipe is set on the side wall of the storage tank and is set close to the bottom of the semi-circular groove; the discharge trough is set directly below the storage tank; the discharge trough is set at an inclination; a discharge scraper is slidably installed in the discharge trough; and the discharge scraper is connected to a pull handle.

[0015] A method for using the yeast waste debittering and decolorizing device described above includes the following steps: S1, feeding: muddy yeast waste is injected into the treatment tank through the feed pipe. The yeast waste enters the semi-circular trough of the treatment section. A mixture of distilled water, bentonite, and protease is injected into the semi-circular trough in advance; S2, debittering and decolorizing: the liquid in the semi-circular trough is stirred by controlling the rotating shaft, connecting crank, and stirring roller through the operating unit. After standing, the reaction occurs. The bentonite fully decolorizes the yeast waste, and the protease debitters the yeast waste; S3, yeast waste recovery: a large number of bubbles are continuously generated in the semi-circular trough through the operating unit. The bubbles carry the floating yeast waste and are recovered by the waste recovery unit; S4, bentonite recovery: the bentonite that has completed color absorption in the semi-circular trough is released into the storage tank, which continuously receives it until the bentonite sedimentation height is close to the height of the drain pipe. The liquid portion is discharged through the drain pipe, and the bentonite is discharged from the storage tank through the discharge trough.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) The mixing liquid in the semi-circular tank is continuously generated by the control unit. Food-grade foaming agent can be added to the semi-circular tank through the feed pipe to improve the foaming efficiency. The treated yeast waste is carried up by the bubbles and recycled by the waste recycling unit. The bentonite component in the mixed liquid accumulates at the bottom of the semi-circular tank due to its own weight. After the yeast waste is recycled, the bentonite and the mixed liquid are released into the storage tank. The semi-circular tank is closed and the debittering and decolorization treatment of the yeast waste continues until enough bentonite is received in the storage tank. Then, the bentonite is recycled by combining the drain pipe and the discharge trough.

[0018] (2) The rotating shaft is driven by the drive motor, so that the mounting bracket and connecting crank on the rotating shaft rotate together. The stirring roller set on the connecting crank continuously stirs the mixed liquid and yeast waste in the semi-circular tank, so that the yeast waste and the bentonite and protease in the mixed liquid can fully contact and react to complete the debittering and decolorization treatment.

[0019] (3) An inner groove and a bubble outlet are provided on one side of the bubble holder. When the rotating shaft rotates clockwise, the back of the bubble holder enters the mixed liquid first, and the foaming is limited at this time. When foaming is required, the rotating shaft rotates counterclockwise, the inner groove enters the mixed liquid first, and the gas in the inner groove is squeezed out through the bubble outlet, thereby generating a large number of bubbles and achieving rapid foaming.

[0020] (4) After the mixed liquid and bentonite components enter the storage tank, the bentonite accumulates at the bottom of the storage tank after sedimentation. The liquid components, combined with protease, can return to the feed pipe through the drain pipe and be sent into the semi-circular tank to continue the debittering treatment. When the bentonite accumulates to the height of the drain pipe, the debittering and decolorization treatment is stopped, and the bentonite in the storage tank is cleaned out by the discharge scraper and the pull handle.

[0034] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0035] like Figure 1 , Figure 2 , Figure 5 As shown, a yeast waste debittering and decolorizing device includes a processing box 1, which is fixedly mounted on a support. The processing box 1 is connected to a feed pipe 10, which is located at the top of the processing box 1. The processing box 1 has a processing section 3 inside, which includes a semi-circular groove 30 that divides the processing box 1 into upper and lower sides. A waste residue recovery section 2 is located on the upper side of the processing box 1 outside the semi-circular groove 30. A storage tank 5 is located on the lower side of the processing box 1 below the processing section 3. The semi-circular groove 30 is used to receive the yeast waste transported by the feed pipe 10. Bentonite is placed inside the semi-circular groove 30. A drain pipe 11 is provided on the side wall of the storage tank 5. A discharge trough 12 is provided at the bottom of the storage tank 5. The waste residue recovery section 2 is located on the outer side of the processing box 1 outside the processing section 3. An operating section 4 is located inside the semi-circular groove 30.

[0036] Specifically, after yeast separation, the yeast waste residue still contains a large amount of water, existing in a solid-liquid mixture, generally muddy, viscous, and with poor flowability. The yeast waste residue is introduced into the treatment tank 1 through the feed pipe 10 and received by the semi-circular trough 30. The semi-circular trough 30 is pre-filled with a mixture of distilled water, bentonite, and protease through the feed pipe 10. After the yeast waste residue falls into the semi-circular trough 30, the operating unit 4 drives a full reaction between the yeast waste residue and the mixed liquid. The bentonite absorbs the pigments in the yeast waste residue, while the protease further hydrolyzes the bitterness sources in the yeast waste residue, namely small molecule peptides, into smaller amino acids or short peptides, thereby reducing bitterness and achieving debittering and decolorization of the yeast waste residue. This effectively improves the palatability of the feed made from the yeast waste residue, ensuring livestock's willingness to eat. Furthermore, the decolorized yeast waste residue makes the feed more visually appealing to farmers, thus improving the overall acceptability of the yeast waste residue feed.

[0037] After the yeast waste residue undergoes decolorization and debittering treatment, the mixed liquid in the semi-circular tank 30 continuously generates a large number of bubbles through the control unit 4. Food-grade foaming agent can be added to the semi-circular tank 30 through the feed pipe 10 to improve foaming efficiency. The bubbles carry the treated yeast waste residue to the waste residue recovery unit 2 for recycling. The bentonite component in the mixed liquid accumulates at the bottom of the semi-circular tank 30 due to its own weight. After the yeast waste residue is recycled, the bentonite and mixed liquid are released into the storage tank 5, the semi-circular tank 30 is closed, and the debittering and decolorization treatment of the yeast waste residue continues until the storage tank 5 receives enough bentonite. Then, the bentonite is recycled by combining the drain pipe 11 and the discharge trough 12.

[0038] like Figure 2 , Figure 5 , Figure 6 As shown, the operating unit 4 includes a drive motor 40, which is fixedly installed on the outside of the processing box 1. The drive motor 40 is connected to a rotary shaft 41, which is coaxially installed with the central axis of the semi-circular groove 30. A mounting bracket 42 is fixedly installed on the rotary shaft 41, and a connecting crank 43 is installed on the mounting bracket 42. An agitating roller 45 is installed on the connecting crank 43. Side blocking plates 300 are sealed on both sides of the semi-circular groove 30. Connecting cranks 43 are respectively installed at both ends of the mounting bracket 42. The agitating roller 45 is rotatably installed between one of the connecting cranks 43. A bubble holder 44 is installed on the other connecting crank 43. An inner groove 440 is provided inside the bubble holder 44, and bubble outlet holes 441 are evenly arranged inside the inner groove 440.

[0039] Specifically, the drive motor 40 drives the rotary shaft 41 to rotate, causing the mounting bracket 42 and the connecting crank 43 on the rotary shaft 41 to rotate together. The stirring roller 45 set on the connecting crank 43 continuously stirs the mixed liquid and yeast waste in the semi-circular trough 30, so that the yeast waste and the bentonite and protease in the mixed liquid can fully contact and react to complete the debittering and decolorization treatment.

[0040] More specifically, after debittering and decolorization, in order to achieve rapid foaming of the mixed liquid and carry away yeast residue, thus separating the yeast residue from the bentonite, a bubble rack 44 is installed on another connecting crank 43. An inner groove 440 and a bubble outlet 441 are provided on one side of the bubble rack 44. When the rotating shaft 41 rotates clockwise (refer to...), Figure 4 The back of the bubble holder 44 enters the mixed liquid first, at which point foaming is limited. When foaming is needed, the rotating shaft 41 rotates counterclockwise, and the inner groove 440 enters the mixed liquid first. The gas in the inner groove 440 is squeezed out through the bubble holes, thereby generating a large number of bubbles and achieving rapid foaming. If necessary, edible foaming agent can be added to the semi-circular groove 30 through the feed pipe 10 to further increase the foaming rate.

[0041] Furthermore, such as Figure 5 , Figure 7 , Figure 8 As shown, the bottom of the semicircular groove 30 is uniformly provided with release holes 301. A snap-fit ​​bracket 31 is provided at the bottom of the semicircular groove 30 corresponding to the release holes 301. An arc-shaped sliding groove 32 is provided in the snap-fit ​​bracket 31. A sealing plate 33 is slidably installed in the arc-shaped sliding groove 32. The sealing plate 33 is set in close contact with the bottom of the semicircular groove 30. A push-pull cylinder 34 is fixedly installed at the bottom of the semicircular groove 30. The end of the push-pull cylinder 34 is connected to the sealing plate 33. A rubber pad is provided on the side of the sealing plate 33 facing the release hole 301.

[0042] Specifically, during the debittering and decolorization process, the release hole 301 is closed. After debittering and decolorization are completed, and the yeast waste is separated from the bentonite mixture liquid through the waste recovery section 2, the release hole 301 is opened, allowing the mixed liquid containing bentonite to enter the storage tank 5 below. The liquid contains protease and can be reused. It is separated through the drain pipe 11 and returned to the semi-circular tank 30 through the feed pipe 10. The bentonite that absorbs the pigment settles at the bottom of the storage tank 5. The release hole 301 is controlled to open and close by the sealing plate 33. The push-pull cylinder 34 drives the sealing plate 33 to slide back and forth in the arc-shaped slide groove 32, thereby controlling the opening or closing of the release hole 301.

[0043] Furthermore, such as Figure 9 , Figure 10 , Figure 11As shown, the waste residue recycling unit 2 includes a recycling box 20. A recycling filter cylinder 21 is provided at the connection between the recycling box 20 and the side wall of the processing box 1. The recycling filter cylinder 21 is installed across the recycling box 20 and the processing box 1. A driven pulley 22 is provided at the end of the recycling filter cylinder 21. A driving pulley 23 is installed at the part of the rotating shaft 41 located outside the processing box 1. A transmission belt 24 is provided between the driven pulley 22 and the driving pulley 23. The recycling filter cylinder 21 is provided with a hollow groove 210. The hollow groove 210 is closed at one end and open at the other end. A sealing ring 211 is installed at the open end of the recycling filter cylinder 21. The sealing ring 211 is rotatably fitted with the end of the hollow groove 210. An air pipe 27 is connected to the sealing ring 211. The air pipe 27 is interconnected with the hollow groove 210. An air pump 28 is connected to the air pipe 27. The air pump 28 is fixedly installed on the outer wall of the recycling box 20.

[0044] Furthermore, such as Figure 11 As shown, the upper and lower sides of the recycling filter cartridge 21 are installed in contact with the side wall of the processing box 1. A baffle plate 26 is provided inside the recycling box 20, and the baffle plate 26 is inserted into the gap of the recycling filter cartridge 21 at an upward angle.

[0045] Specifically, after sufficient aeration, yeast waste adheres to the surface of the bubbles. The bubbles carry the yeast waste into the gaps between the blades on the surface of the recovery filter cartridge 21. The recovery filter cartridge 21 is driven by the rotating shaft 41, the driving pulley 23, the transmission belt 24, and the driven pulley 22 to achieve continuous rotation. At the same time, the hollow groove 210 set inside the recovery filter cartridge 21, as well as the sealing ring 211 and the air pipe 27 set at one end, create a negative pressure state on the surface of the recovery filter cartridge 21. After the bubbles carrying the yeast waste reach the gaps between the blades on the surface of the recovery filter cartridge 21, the bubbles burst rapidly, and the yeast waste adheres to the surface of the gaps between the blades of the recovery filter cartridge 21. After the recovery filter cartridge 21 rotates into the recovery box 20, the yeast waste is detached by the blocking effect of the baffle plate 26, thus obtaining the yeast waste after debittering and decolorization treatment.

[0046] Furthermore, such as Figure 2 , Figure 3 As shown, the feed pipe 10 is connected to a horizontal pipe 100 at the upper end of the semi-circular groove 30. The bottom of the horizontal pipe 100 is uniformly provided with leakage holes 101. The inner diameter of the horizontal pipe 100 is smaller than the inner diameter of the feed pipe 10. The two ends of the horizontal pipe 100 are closed.

[0047] Specifically, the horizontal pipe 100 allows the sludge-like yeast residue to fall evenly into the semi-circular trough 30. The inner diameter of the horizontal pipe 100 is smaller than the inner diameter of the feed pipe 10, ensuring the yeast residue is fully squeezed into the horizontal pipe 100. It is also important to note that the horizontal pipe 100 should be positioned offset from directly above the rotating shaft 41 to prevent yeast residue from dripping onto the rotating shaft 41 after detaching from the horizontal pipe 100.

[0048] Furthermore, such as Figure 2 , Figure 5 , Figure 12 As shown, the drain pipe 11 is set on the side wall of the storage tank 5 and is set against the bottom of the semi-circular groove 30. The discharge trough 12 is set directly below the storage tank 5. The discharge trough 12 is set at an inclination. A discharge scraper 13 is slidably installed in the discharge trough 12. The discharge scraper 13 is connected to a pull handle 14.

[0049] Specifically, after the mixed liquid and bentonite components enter the storage tank 5, the bentonite accumulates at the bottom of the storage tank 5 after sedimentation. The liquid components, combined with the protease, can return to the feed pipe 10 through the drain pipe 11 and be sent into the semi-circular tank 30 to continue the debittering treatment. When the bentonite accumulation reaches the height of the drain pipe 11, the debittering and decolorization treatment is stopped, and the bentonite in the storage tank 5 is cleaned out by the discharge scraper 13 and the pull handle 14.

[0050] This invention also discloses a method for using the yeast waste debittering and decolorizing device described above, comprising the following steps: S1, feeding: muddy yeast waste is injected into the treatment tank 1 through the feed pipe 10, and the yeast waste enters the semi-circular trough 30 of the treatment section 3. A mixture of distilled water, bentonite, and protease is injected into the semi-circular trough 30 in advance; S2, debittering and decolorizing: the liquid in the semi-circular trough 30 is stirred by the rotating shaft 41, connecting crank 43, and stirring roller 45 controlled by the operating unit 4. After standing, the reaction is carried out, and the bentonite fills the yeast waste. S3. Decolorization: Protease debitteres the yeast waste residue. S4. Yeast waste residue recovery: The control unit 4 continuously generates a large number of bubbles in the semi-circular tank 30. The bubbles carry the floating yeast waste residue to the waste residue recovery unit 2 for recovery. S5. Bentonite recovery: The bentonite that has completed color absorption in the semi-circular tank 30 is released into the storage tank 5, which continuously receives it until the bentonite sedimentation height is close to the height of the drain pipe 11. The liquid portion is discharged through the drain pipe 11, and the bentonite is discharged from the storage tank 5 through the discharge chute 12.

[0051] The working principle of this invention embodiment is as follows:

[0052] like Figures 1-12As shown, after the yeast waste residue undergoes decolorization and debittering treatment, the mixed liquid in the semi-circular tank 30 continuously generates a large number of bubbles through the control unit 4. Food-grade foaming agent can be added to the semi-circular tank 30 through the feed pipe 10 to improve foaming efficiency. The bubbles carry the treated yeast waste residue to the waste residue recovery unit 2 for recycling. The bentonite component in the mixed liquid accumulates at the bottom of the semi-circular tank 30 due to its own weight. After the yeast waste residue is recycled, the bentonite and mixed liquid are released into the storage tank 5, the semi-circular tank 30 is closed, and the debittering and decolorization treatment of the yeast waste residue continues until the storage tank 5 receives enough bentonite. Then, the bentonite is recycled by combining the drain pipe 11 and the discharge trough 12. The drive motor 40 drives the rotary shaft 41 to rotate, causing the mounting bracket 42 and connecting crank 43 on the rotary shaft 41 to rotate together. The stirring roller 45 on the connecting crank 43 continuously stirs the mixed liquid and yeast waste in the semi-circular trough 30, allowing the yeast waste to fully contact and react with the bentonite and protease in the mixed liquid, thus completing the debittering and decolorization treatment. After debittering and decolorization, in order to achieve rapid foaming of the mixed liquid and carry away the yeast waste, thereby separating the yeast waste from the bentonite, a bubble frame 44 is set on another connecting crank 43. An inner groove 440 and a bubble outlet 441 are set on one side of the bubble frame 44. When the rotary shaft 41 rotates clockwise, the back of the bubble frame 44 enters the mixed liquid first, and the foaming is limited at this time. When foaming is required, the rotary shaft 41 rotates counterclockwise, and the inner groove 440 enters the mixed liquid first. The gas in the inner groove 440 is squeezed out through the bubble outlet, thereby generating a large number of bubbles and achieving rapid foaming. If necessary, edible foaming agents can be added to the semi-circular trough 30 via the feed pipe 10 to further increase the bubble rate. During the debittering and decolorizing process, the release hole 301 is closed. After the debittering and decolorizing is completed, and the yeast waste is separated from the bentonite mixture liquid via the waste recovery section 2, the release hole 301 is opened, allowing the mixed liquid containing bentonite to enter the storage tank 5 below. The liquid contains protease and can be reused. It is separated through the drain pipe 11 and returned to the semi-circular trough 30 via the feed pipe 10. The bentonite that absorbs the pigment settles at the bottom of the storage tank 5. The release hole 301 is controlled to open and close by the sealing plate 33. The push-pull cylinder 34 drives the sealing plate 33 to slide back and forth in the arc-shaped slide groove 32, thereby controlling the opening or closing of the release hole 301.After sufficient aeration, yeast waste adheres to the surface of the bubbles. The bubbles carry the yeast waste into the gaps between the blades on the surface of the recovery filter cartridge 21. The recovery filter cartridge 21 is driven by the rotating shaft 41, the driving pulley 23, the transmission belt 24, and the driven pulley 22 to achieve continuous rotation. At the same time, the hollow groove 210 set inside the recovery filter cartridge 21, the sealing ring 211 set at one end, and the air pipe 27 create a negative pressure state on the surface of the recovery filter cartridge 21. After the bubbles carrying the yeast waste reach the gaps between the blades on the surface of the recovery filter cartridge 21, the bubbles burst rapidly. The yeast waste adheres to the surface of the gaps between the blades of the recovery filter cartridge 21. After the recovery filter cartridge 21 rotates into the recovery box 20, the yeast waste is blocked by the baffle plate 26, thus achieving the removal of yeast waste after debittering and decolorization treatment. After the mixed liquid and bentonite components enter the storage tank 5, the bentonite accumulates at the bottom of the storage tank 5 after sedimentation. The liquid components, combined with the protease, can return to the feed pipe 10 through the drain pipe 11 and be sent into the semi-circular tank 30 to continue the debittering treatment. When the bentonite accumulates to the height of the drain pipe 11, the debittering and decolorization treatment is stopped, and the bentonite in the storage tank 5 is cleaned out by the discharge scraper 13 and the pull handle 14.
