Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of solid-state vinegar processing, and particularly to an intelligent fermentation system with a liquefaction injection mechanism. Background Art
[0002] Vinegar, as a traditional condiment, has a history of thousands of years in our country. With the progress of technology, the industrial production of vinegar has become increasingly mature, but there are still some problems in the preparation process. The traditional vinegar preparation process generally needs to go through steps such as feeding, liquefaction, saccharification, fermentation, and brewing. Among these steps, liquefaction and saccharification are the key links, directly affecting the quality and yield of vinegar.
[0003] In the vinegar preparation process, liquefaction is to transform the starch in the raw materials from a granular state into a dissolved state, reduce the viscosity, facilitate the full contact between the subsequent saccharifying enzyme and starch, and improve the saccharification efficiency. However, the traditional liquefaction and saccharification processes need to be carried out in different equipment, which undoubtedly increases the equipment investment and operation costs. In addition, the method of adsorbing amylase into a flexible tube body by high-temperature and high-pressure steam for mixing, although to a certain extent realizes the continuous progress of liquefaction and saccharification, still has many problems.
[0004] Firstly, the investment in multiple equipment or tanks leads to an increase in production costs. Secondly, by using the method of high-temperature and high-pressure steam adsorption, liquefaction and saccharification are carried out in a flexible tube body space, and the saccharified liquid is easy to hang on the wall or block the holes, resulting in uneven mixing. This phenomenon not only affects the saccharification effect but also may lead to a decline in the quality of vinegar. Therefore, how to achieve efficient and uniform mixing of liquefaction and saccharification has become an urgent problem to be solved in the field of vinegar preparation. Summary of the Invention

When the steam cylinder is at the movement apex position, the inner nozzle and the outer nozzle correspond to each other one by one to form a nozzle structure, and the nozzle structure faces the slope plate; when the steam cylinder is at the movement bottom position, a spraying channel is formed between the bottom and the deflector.

[0009] Preferably, the bottom of the steam cylinder extends downward to form an air outlet pipe surrounding the circumference of the deflector, and a gap is formed between the deflector and the air outlet pipe; a cover plate is arranged on the top of the deflector; wherein, when the steam cylinder is at the movement bottom position, the cover plate disengages from the steam cylinder, and an annular gap is formed between the cover plate and the bottom of the steam cylinder, and the annular gap and the gap form a spraying channel.
[0010] Preferably, the spraying channel is arranged towards the liquefaction nozzle, and the bottom holes are arranged around the circumference of the spraying channel;
[0011] Under the main view projection, the bottom holes are inclined holes from top to bottom.
[0012] Preferably, an inner reaction clamping cavity is formed between the steam spray cylinder and the inner reaction tank; the steam cylinder is a straight cylinder, the inner reaction tank is a conical cylinder, and the width of the inner reaction clamping cavity gradually narrows from top to bottom.

[0018] Advantages of the present invention: By using an intelligent fermentation system with a liquefaction injection mechanism provided by the present invention, compared with the prior art, the following technical effects are achieved:
[0019] 1. By adopting the method of steam ejection, during the process of the raw materials flowing on the slope plate, they are in a continuous spiral movement, flowing downward, spiral movement, and flowing downward state, enabling amylase and the like to be fully mixed with high-pressure steam to form a uniformly mixed saccharified liquid. The raw materials and high-temperature steam are continuously mixed in a spiral movement and downward flowing form on the surface of the slope plate, causing the saccharified liquid to flow in a uniformly distributed manner on a table body.
[0020] 2. During the process of the raw materials flowing on the slope plate, they pass through each diversion groove in sequence, effectively delaying the downward flow speed, which is conducive to the full mixing of amylase and the like with high-pressure steam. The method of steam ejection effectively avoids the blockage of the holes by the saccharified liquid and prevents the situation of steam cylinder wall hanging, reducing the equipment maintenance cost.
[0021] 3. The intermittent high-pressure steam is ejected from the outer spray ports arranged in the spiral direction, causing the high-pressure steam to be sprayed in a swirling manner into the diversion grooves on the surface of the slope plate, realizing the continuous spiral movement and downward flowing form of mixing of the raw materials and high-temperature steam on the surface of the slope plate, and improving the mixing uniformity of the saccharified liquid. As the width of the inner reaction clamping cavity gradually becomes narrower from the top to the bottom, the spraying distance of the high-temperature steam also gradually becomes smaller, and the spraying force gradually increases. This makes the pressure at the bottom of the inner reaction clamping cavity greater than that at the top, increasing the impact force received by the saccharified liquid and further improving the mixing effect.

Specific implementation mode
[0031] In order to better explain the present invention for easy understanding, the present invention will be described in detail below in conjunction with the accompanying drawings through specific implementation modes. The present invention discloses an intelligent fermentation system with a liquefaction spraying mechanism. The fermentation system includes a wind elevator and a fermenter, and a liquefaction mechanism is arranged between the wind elevator and the fermenter. The liquefaction mechanism includes an inner reaction box, and a steam spray cylinder is arranged in the middle of the inner cavity of the inner reaction box, including an inner and outer sleeved steam cylinder and an inner cylinder fixed in the inner reaction box; the steam cylinder is driven by a telescopic cylinder to reciprocate up and down in the inner cylinder, and the steam cylinder forms a movement apex position and a movement bottom position. When the steam cylinder is at the movement apex position, the inner spray nozzle and the outer spray nozzle are in one-to-one correspondence to form a spray hole structure, and the spray hole structure faces the slope plate; when the steam cylinder is at the movement bottom position, a spraying channel is formed between the bottom and the flow guide body. High-pressure steam intermittently sprays out from the steam cylinder through the spray hole structure and the spraying channel, so that the raw materials are saccharified by the intermittently sprayed high-pressure steam during the process of flowing on the slope plate; at the same time, when flowing to the liquefaction spray nozzle after saccharification, it is washed into the conveying pipeline by the intermittently sprayed high-pressure steam. The high-pressure steam forms a continuous spiral movement, downward flow, spiral movement, and downward flow state when flowing on the surface of the slope plate, so that amylase and the like are fully mixed with the high-pressure steam to form a uniformly mixed saccharified liquid.
[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. As long as the effects of the present invention can be exerted, various changes can be made to the implementation solutions.
[0033] Those skilled in the art connect the components in this case in sequence. For the specific connection and operation sequence, reference should be made to the following working principle. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process.
[0034] Such as Figures 1 to 7As shown, an embodiment of the present application proposes an intelligent fermentation system with a liquefaction injection mechanism, which includes a wind lift 1 and a fermentation tank 4. A liquefaction mechanism is arranged between the wind lift 1 and the fermentation tank 4. The raw materials enter the liquefaction mechanism through the wind lift 1, and then the clear liquid that has been liquefied and saccharified is pumped into the fermentation tank 3 for fermentation.
[0035] In this embodiment, if Figures 6 - 7 As shown, the liquefaction mechanism includes an inner reaction box 9, an outer heat-insulating shell 3 is arranged outside the inner reaction box 9, and an outer sandwich chamber 22 is formed between the outer heat-insulating shell 3 and the inner reaction box 9. The outer sandwich chamber 22 here is used to insulate the inner reaction box 9, and can also be connected to a high-temperature steam pipeline to input high-temperature steam into the outer sandwich chamber 22 to improve the heat preservation of the outer sandwich chamber 22. It should be noted that when high-temperature steam is input, water will be formed in the outer sandwich chamber 22, so a drain pipe needs to be connected to the bottom of the outer heat-insulating shell 3 to discharge the water.
[0036] like Figure 2 As shown, in this embodiment, the top of the inner reaction box 9 is provided with a feed inlet 8, and a ring box 7 is fixed around the top. The wind lift 1 is connected to the ring box 7 through a feed pipe. The bottom of the ring box 7 is connected to the feed inlet 8; the feed inlet 8 is as shown in FIG. Figure 2 and Figure 5 As shown, the top of the inner reaction box 9 is arranged in an arc shape, and the raw material is blown into the annular box 7 through the wind lift 1. The raw material rotates inside the annular box 7 and falls into the inner reaction box 9 through multiple feed ports 8. A discharge port is arranged at the bottom of the inner reaction box 9, and a liquefaction nozzle 17 is arranged at the discharge port. The liquefaction nozzle 17 is connected to the fermentation tank 3 through a conveying pipeline, and a conveying pump is arranged on the conveying pipeline. The clear liquid after liquefaction and saccharification is pumped into the fermentation tank 3 by the conveying pump.
[0037] In this embodiment, if Figure 2 and Figures 6 - 7 As shown, a steam spray is arranged in the middle of the inner cavity of the inner reaction box 9, including a steam spray 11 connected inside and outside and an inner cylinder 13 fixed in the inner reaction box 9; a ramp plate 10 is arranged on the inner side of the inner reaction box 9 along the direction from the inlet 8 to the outlet; wherein, an inner reaction cavity 24 is formed between the steam spray and the inner reaction box 9; wherein, the steam spray 11 is a straight cylinder, the inner reaction box 9 is a conical cylinder, the ramp plate 10 is also a conical cylinder, fixed on the inner wall of the inner reaction box 9, and the width of the inner reaction cavity 24 gradually narrows from the top to the bottom. During implementation, the raw material enters the inner reaction cavity 24 through the inlet 8 and falls onto the inner reaction cavity 24. After being sprayed out from the steam spray, the high-pressure steam entrains the raw material and sprays it on the ramp plate 10, so that the raw material is saccharified by the high-pressure steam in the process of flowing downward on the surface of the ramp plate 10.
[0038] Preferably, a plurality of inner nozzles 20 are formed in the side wall of the steam cylinder 11, a plurality of outer nozzles 18 and bottom holes 19 are respectively formed in the side wall and the bottom of the inner cylinder 13, and a fluid guide 15 extending into the steam cylinder 11 is fixed above the liquefaction nozzle 17.
[0039] A telescopic cylinder 6 is arranged at the top of the inner reaction tank 9. The telescopic cylinder 6 can be an electric telescopic rod or a pneumatic cylinder. The steam cylinder 11 is driven by the telescopic cylinder 6 to reciprocate up and down in the inner cylinder 13, and the steam cylinder 11 forms a movement apex position and a movement bottom position. When the steam cylinder 11 is at the movement apex position, the inner nozzles 20 and the outer nozzles 18 correspond to each other one by one to form a nozzle structure, and the nozzle structure faces the slope plate 10. At this time, the high-pressure steam in the steam cylinder 11 is ejected through the nozzle structure and acts on the slope plate 10; when the steam cylinder 11 is at the movement bottom position, a spraying channel is formed between the bottom and the fluid guide 15, and the spraying channel faces the liquefaction nozzle 17. At this time, the high-pressure steam in the steam cylinder 11 is sprayed towards the liquefaction nozzle 17 through the spraying channel.
[0040] A high-pressure steam inlet pipe 5 is connected to the top of the steam cylinder 11. The high-pressure steam inlet pipe 5 is connected to the steam cylinder 11 through a hose. It should be noted here that the hose can also be a corrugated pipe to ensure that the high-pressure steam inlet pipe 5 can smoothly transport high-pressure steam into the steam cylinder 11 when the steam cylinder 11 reciprocates up and down.
[0041] It should be described in detail that when the high-pressure steam is ejected from the nozzle structure, the steam cylinder abuts against the top cover plate of the fluid guide 15 at this time, so that the spraying channel is closed. And when the high-pressure steam is ejected from the spraying channel, the inner nozzles 20 and the outer nozzles 18 are misaligned, that is, in a non-concentric state, and the inner nozzles 20 are closed by the wall surface of the inner cylinder 13. By adopting this design method, the high-pressure steam is intermittently ejected from the nozzle structure and the spraying channel in the steam cylinder 11, so that the raw material is saccharified by the intermittently ejected high-pressure steam during the flowing process on the slope plate 10; at the same time, when it flows to the liquefaction nozzle 17 after saccharification, it is flushed into the conveying pipeline by the intermittently ejected high-pressure steam.
[0042] Exemplarily, a flow guiding groove 21 is spirally arranged on the inner wall surface of the slope plate 10 from top to bottom, and the outer spray nozzles 18 are spirally arranged on the side wall of the inner cylinder 13 from top to bottom and are correspondingly arranged with the flow guiding groove 21; an air outlet nozzle 14 is arranged on the outside of each outer spray nozzle 18, and the air outlet direction of the air outlet nozzle 14 is the same as the spiral rotation direction of the outer spray nozzle 18. When the raw material flows on the slope plate 10, it passes through each flow guiding groove 21 in sequence to delay the downward flow speed; moreover, intermittent high-pressure steam is sprayed out from the spirally arranged outer spray nozzles 18, so that the high-pressure steam is sprayed in a swirling manner into the flow guiding groove 21 on the surface of the slope plate 10. The high-pressure steam carries the raw material and moves spirally in the flow guiding groove 21 within the slope plate 10, so that the high-pressure steam moves in a continuous spiral, downward flow, spiral movement, and downward flow state when flowing on the surface of the slope plate 10, enabling enzymes such as amylase to be fully mixed with the high-pressure steam to form a uniformly mixed saccharified liquid.
[0043] It should be specifically explained that the raw material and high-temperature steam are mixed in a continuous spiral movement and downward flow form on the surface of the slope plate 10, so that the saccharified liquid flows uniformly on a table body. Moreover, compared with the way of sucking in the raw material, the way of spraying steam effectively avoids the blockage of the holes by the saccharified liquid and prevents the steam cylinder 11 from having a wall hanging situation. At the same time, as the width of the inner reaction clamping cavity 24 gradually narrows from top to bottom, the spraying distance of the high-temperature steam also gradually becomes smaller, so the spraying force also gradually increases. At this time, the circumferential space that the high-temperature steam can move after being sprayed also decreases, and then the pressure at the bottom of the inner reaction clamping cavity 24 is greater than that at the top. Therefore, the impact force received by the saccharified liquid increases, and the mixing effect gradually increases.
[0044] In this embodiment, an air outlet pipe 16 surrounding the circumferential direction of the deflector 15 is formed by the downward extension of the bottom of the steam cylinder 11; a gap 23 is formed between the deflector 15 and the air outlet pipe 16; a cover plate is arranged at the top of the deflector 15; wherein, when the steam cylinder 11 is at the moving bottom position, the cover plate is separated from the steam cylinder 11, and an annular gap 25 is formed between the cover plate and the bottom of the steam cylinder 11, and the annular gap 25 and the gap 23 constitute a spraying channel.
[0045] The spraying channel is arranged towards the liquefaction spray nozzle 17, and the bottom holes 19 are arranged around the circumferential direction of the spraying channel; in addition, the bottom holes 19 here are inclined holes from top to bottom in the main view projection. When the high-pressure steam in the steam cylinder 11 is sprayed out through the spraying pipeline, a negative pressure is formed at the spatial position between the air outlet pipe 16 and the bottom of the inner cylinder 13. Under the action of the negative pressure adsorption and the action of gravity flow, the saccharified liquid converged at the bottom of the inner reaction clamping cavity 24 flows out through the bottom holes 19 and is carried by the high-pressure steam and sprayed to the liquefaction spray nozzle 17. At this time, a secondary contact between the high-pressure steam and the saccharified liquid is formed, further improving the saccharification effect.
[0046] In this embodiment, a baffle 12 is provided at the top of the inner reaction clamping chamber 24. Exemplarily, the baffle 12 is a cone with a trapezoidal cross-section, and its bottom end faces the top of the slope plate 10. The function of the baffle 12 is to block and guide the high-pressure steam, preventing the high-pressure steam from directly acting on the feed inlet 8 when it is ejected from the spray hole structure.
[0047] In a preferred embodiment of this embodiment, the fermentation system further includes a control system. The control system includes a controller and a detector 2. The detector 2 is a pipeline wind speed detector. The detector 2 is arranged on the feed pipeline. Both the detector 2 and the power device of the air lift 1 are electrically connected to the controller. It also includes a solenoid valve, which is arranged at the high-pressure steam inlet pipe 5.
[0048] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
