Description

Technical Field

[0001] The invention relates to the technical field of yeast culture mixed solution concentration measurement, and in particular to a device for efficiently converting starch into yeast and a culture method. Background Art

[0002] The following problems exist when measuring a yeast culture mixed solution: 1. The existing technology manually takes out a sample from a barrel and then measures the solution using a test paper. The solution is in a fixed container, and the distribution of the various compounds in the storage container is uneven. Simply extracting and measuring from a certain part of the container will lead to a decrease in measurement accuracy; 2. When measuring a solution, a single tube of a single solution cannot fully represent the concentration of the solution, errors will occur, and it is not easy to compare.

[0003] Chinese patent CN221123955U discloses a yeast culture mixed solution concentration measuring device, comprising a bottom plate, a bottom frame welded to the bottom plate, a lifting mechanism installed on the bottom frame, a sampling mechanism installed on the top of the lifting mechanism, a cavity opened on the top of the bottom plate, a slide groove opened on the rear side of the bottom plate, a classification mechanism installed on the top of the bottom plate, and a detection mechanism installed on the top of the slide groove; the lifting mechanism comprises a screw rod, the screw rod is rotatably connected to the bottom frame, a round rod is welded on the right side of the bottom frame, a motor is bolted to the top of the bottom plate, the output end of the motor is connected to the screw rod, a moving sleeve is threadedly connected to the screw rod, and the moving sleeve is slidably connected to the round rod.

[0004] Although the above scheme can realize the sampling of the solution and the detection of the sample concentration after sampling, the growth environment of the yeast needs to be strictly controlled during the yeast culture process. Yeast can reproduce rapidly in an aerobic environment, and yeast can produce alcohol when it is put into a sugar solution in an anaerobic environment. The ultimate purpose of yeast reproduction is to apply it to actual production. In the existing technology of fermentation by yeast, there is a method of decomposing starch into sugar solution by amylase and then putting yeast into it, and providing sufficient oxygen for the yeast so that the yeast can fully reproduce in the sugar solution, and then placing the yeast and the sugar solution in an anaerobic environment so that the yeast uses the sugar solution for fermentation in an anaerobic environment. The yeast reproduction and fermentation process by yeast are mostly carried out separately, and the concentration of the sugar solution needs to be strictly monitored when the yeast is reproduced and fermented by the yeast. Too high or too low concentration will lead to reduced yeast reproduction efficiency and reduced yeast fermentation efficiency. However, the existing detection method is to manually detect the concentration of the sugar solution, which is inefficient. Summary of the invention

[0005] In view of the above problems, a device and a cultivation method for efficiently converting starch into yeast are provided. A sugar content detection unit is provided so that the sugar content detection unit can automatically detect the concentration of sugar solution in a breeding barrel. A paste containing starch and amylase are added into the breeding barrel. The amylase decomposes the starch in the paste into sugar solution. The sliding block is located at the end of the detection shell facing the breeding barrel. A cleaning cavity is formed on one side of the sliding block. The sugar content detector is located in the cleaning cavity. The sliding block moves in the detection shell in a direction away from the breeding barrel. During the movement, a detection cavity is gradually formed on the side of the sliding block close to the breeding barrel. The sugar solution in the breeding barrel is drawn into the detection cavity. After the detection cavity is completely formed, the detection end of the sugar content detector is located in the detection cavity. The sugar content detector detects the concentration of sugar solution in the detection cavity. After the detection of the sugar content detector is completed, the sliding block moves in the detection shell toward the breeding barrel. The sliding block moves toward the breeding barrel. The detection cavity on one side of the breeding barrel gradually shrinks, and the sugar liquid in the detection cavity is pushed back into the breeding barrel by the sliding block. At the same time, a cleaning cavity is gradually formed on the side of the sliding block away from the breeding barrel. When the sliding block reaches the end of the detection shell close to the breeding barrel, the cleaning cavity is completely formed, and cleaning liquid is injected into the cleaning cavity. The cleaning liquid cleans the detection end of the sugar content detection liquid in the cleaning cavity. The above steps are repeated until the sugar solution concentration reaches the preset concentration, and then the activated yeast is added to the breeding barrel. The sugar content detection unit is used to measure the sugar content concentration in the breeding barrel for multiple times, so that the sugar content can reach the most suitable state for yeast growth or fermentation, thereby realizing automatic detection of sugar content. At the same time, the sugar content detector can be cleaned, and the tested sample can be re-injected into the breeding barrel, which not only ensures the accuracy of sugar content detection, but also reduces unnecessary loss of sugar solution during detection.

DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Reference Figure 1-Figure 4 and Figure 7-10 : A device for efficiently converting starch into yeast, comprising a breeding barrel 1; comprising a sugar content detection unit 2, the sugar content detection unit 2 comprising a detection shell 22 interconnected with the breeding barrel 1, a sugar content detector 21 is arranged on the detection shell 22, a sliding block 23 is slidably arranged in the detection shell 22 along the extension direction of the detection shell 22, the sliding block 23 forms a detection cavity 222 and a cleaning cavity 221 in the detection shell 22 by sliding, when the sliding block 23 slides to the connecting end of the detection shell 22 and the breeding barrel 1, the detection shell 22 on the side of the sliding block 23 away from the breeding barrel 1 forms a cleaning cavity 221, and the detection end of the sugar content detector 21 is located in the cleaning cavity 221, when the sliding block 23 slides to the side of the detection shell 22 away from the breeding barrel 1, the detection shell 22 on the side of the sliding block 23 close to the breeding barrel 1 forms a detection cavity 222, and the detection end of the sugar content detector 21 is located in the detection cavity 222.

[0032] Sugar content refers to the concentration of sugar solution. The upper part of the breeding barrel 1 is provided with amylase and starch input ports, vents and yeast input ports. When the vent is opened, the breeding barrel 1 is in an aerobic state, and when the vent is closed, the breeding barrel 1 is in an anaerobic state. The breeding barrel 1 is provided with a pH detector 11, a temperature sensor 12, a heating wire and a stirring blade 13. The pH detector 11 and the temperature sensor 12 are both arranged on the inner wall of the breeding barrel 1. The pH detector 11 is used to detect the pH in the breeding barrel 1, and the temperature sensor 12 is used to detect the temperature in the breeding barrel 1. The heating wire can heat the breeding barrel 1 after being powered on. The heating wire and the temperature sensor 12 control the temperature in the breeding barrel 1 at 29 degrees. When the temperature in the breeding barrel 1 is lower than 29 degrees, the heating wire is powered on, and the breeding barrel 1 When the temperature inside is higher than 29 degrees, the heating wire is powered off, and the stirring blade 13 is rotated. A driver is set at the bottom of the breeding barrel 1, and the driver is used to drive the stirring blade 13 to rotate. When the yeast is propagated and cultivated, the appropriate concentration of sugar solution, temperature and pH can provide a good breeding environment for the yeast. It is known that yeast can multiply in large quantities in an aerobic environment, and yeast can produce alcohol in an anaerobic environment. Many food processing in life will apply the above principles. The breeding barrel 1 in the present invention can be used in three production environments: solid aerobic, liquid aerobic and liquid anaerobic. Taking dough as an example in a solid aerobic environment, the dough is put into the breeding barrel 1, and then amylase and yeast are put into the breeding barrel 1, and the breeding barrel 1 is kept in an aerobic state. At this time, amylase decomposes the starch in the dough into sugar. After the sugar is used by yeast, water, carbon dioxide and a large amount of heat are produced. The carbon dioxide causes pores in the dough, thus achieving the effect of dough leavening. In the liquid aerobic and liquid anaerobic environments, the liquid is a paste, such as rice paste, and the paste put into the liquid aerobic environment is converted into sugar solution under the action of amylase, and then yeast is put into the breeding barrel 1. The yeast rapidly multiplies in the sugar solution. When the breeding barrel 1 is in the liquid anaerobic environment, paste and amylase are put into the breeding barrel 1. The amylase decomposes the paste and produces sugar solution. The yeast produces alcohol in the anaerobic environment. It is worth noting that whether the liquid is aerobic or anaerobic, there are certain requirements for the concentration of the sugar solution in the liquid. If the concentration of the sugar solution is too high, the yeast will produce alcohol in the anaerobic environment. Or too low is not suitable for yeast reproduction and alcohol production, so a sugar content detection unit 2 is set on one side of the breeding barrel 1, and a driving unit 231 that can push the sliding block 23 to slide in the detection shell 22 is set at the end of the sliding block 23. It is worth noting that the yeast needs to be activated before being put into the breeding barrel 1, so an activation device 14 is set on one side of the breeding barrel 1. The activation device 14 is a prior art, so it is not repeated here. The driving unit 231 includes a driving rod 2311, a first shell 2312 and a first pump body 2313. The driving rod 2311 is fixedly arranged at the end of the sliding block 23 away from the breeding barrel 1 along the moving direction of the sliding block 23, and the first shell 2312 is arranged at the end of the first shell 2312 along the moving direction of the sliding block 23.The first pump body 2313 is arranged at the end of the first shell 2312. The first pump body 2313 can inject gas into the first shell 2312, so that the driving rod 2311 located in the first shell 2312 slides out of the first shell 2312. When the first pump body 2313 extracts the gas from the first shell 2312, the driving rod 2311 retracts into the first shell 2312. The working principle of the sugar content detection unit 2 of the present invention is as follows. When measuring the concentration of the sugar solution, when the measured sugar solution concentration is low, a specified amount of amylase can be added to the breeding barrel 1 according to actual conditions, thereby increasing the concentration of the sugar solution. When the sugar solution concentration reaches the preset concentration, the concentration is stopped, and a paste containing starch and amylase are added into the breeding barrel 1. The amylase decomposes the starch in the paste into sugar solution. The sliding block 23 is located at the end of the detection shell 22 facing the breeding barrel 1 at this time. A cleaning cavity 221 is formed on one side of the sliding block 23, and the sugar content detector 21 is located in the cleaning cavity 221. The sliding block 23 moves in the detection shell 22 in the direction away from the breeding barrel 1. During the movement, the sliding block 23 gradually forms a detection cavity 222 on the side close to the breeding barrel. The sugar solution in the breeding barrel 1 is drawn into the detection cavity 222. After the detection cavity 222 is completely formed, the detection end of the sugar content detector 21 is located in the detection cavity 222, and the sugar content detector 21 detects the concentration of the sugar solution in the detection cavity 222. After the sugar content detector 21 completes the detection, the sliding block 23 moves toward the side of the breeding barrel 1 in the detection shell 22, and the detection cavity 222 of the sliding block 23 toward the side of the breeding barrel 1 gradually shrinks, and the sugar solution in the detection cavity 222 is pushed back into the breeding barrel 1 by the sliding block 23. At the same time, the side of the sliding block 23 away from the breeding barrel 1 gradually forms a cleaning cavity 221. When the sliding block 23 reaches the end of the detection shell 22 close to the breeding barrel 1, the cleaning cavity 221 is completely formed, and cleaning liquid is injected into the cleaning cavity 221. The cleaning liquid cleans the detection end of the sugar content detection liquid in the cleaning cavity 221, and the above steps are repeated until the sugar solution concentration reaches the preset concentration, and then the activated yeast is added to the breeding barrel 1. The sugar concentration in the breeding barrel 1 is measured multiple times by the sugar content detection unit 2, so that the sugar content can reach the most suitable state for yeast growth or fermentation, realizing automatic detection of sugar content. At the same time, the sugar content detector 21 can be cleaned, and the sample after detection can be re-injected into the breeding barrel 1, which not only ensures the accuracy of sugar content detection, but also reduces unnecessary loss of sugar solution during detection.

[0033] Reference Fig.10 A filter screen 24 is provided on one end of the detection shell 22 facing the breeding barrel 1, and the filter screen 24 is used to filter impurities in the sugar solution.

[0034] When the breeding barrel 1 is applied to liquid, whether it is an aerobic liquid environment or an anaerobic liquid environment, it is crucial to control the sugar content. In an aerobic liquid environment, a suitable sugar content can ensure that the yeast fully reproduces, and in an anaerobic liquid environment, a suitable sugar content can ensure that the yeast fully produces alcohol. In production, the liquid is mostly a paste, that is, the liquid contains solid impurities. If the solid impurities are sucked into the detection cavity 222, it is not convenient for subsequent cleaning work. After a filter screen 24 is provided at the end of the detection shell 22, it can be ensured that the solid impurities cannot enter the detection cavity 222 formed by the sliding block 23, and when the sliding block 23 squeezes out the sugar liquid in the detection shell 22, the squeezed sugar liquid can clean the solid impurities attached to the filter screen 24, thereby ensuring that the filter screen 24 will not be blocked by solid impurities.

[0035] Reference Fig. 9 and Fig.10 : A cleaning unit 25 is arranged on the cleaning chamber 221, and the cleaning unit 25 includes a water inlet 251 and a water outlet 252. After the sliding block 23 slides in the detection shell 22 to form the cleaning chamber 221, the water inlet 251 is opened and the cleaning liquid is injected into the cleaning chamber 221. After the cleaning is continued for a preset time, the water outlet 252 is opened, and the water outlet 252 discharges the cleaning liquid in the cleaning chamber 221.

[0036] Reference Figure 7-Figure 9 : A stirring unit 253 that can move synchronously with the sliding block 23 is arranged on the side of the sliding block 23 away from the breeding barrel 1, and a stirring blade 2531 is arranged in the stirring unit 253. After a cleaning cavity 221 is formed on one side of the sliding block 23, the water inlet 251 injects cleaning liquid into the cleaning cavity 221, and the stirring blade 2531 starts to rotate.

[0037] The stirring unit 253 includes a stirring pump 2532, a rotating ring 2533 and a circulation pipe 2534. The stirring pump 2532 is fixedly arranged on the driving rod 2311. The inner cavity of the stirring pump 2532 is an annular structure. The rotating ring 2533 is fixedly arranged at the driving end of the stirring pump 2532. The circulation pipe 2534 is arranged on the input end and the output end of the stirring pipe. The inner cavity of the circulation pipe 2534 and the stirring pump 2532 both contain hydraulic oil. The hydraulic oil circulates in the circulation pipe 2534. The hydraulic oil flows in the circulation pipe 2534, and the blades in the agitation pump 2532 can be driven to rotate, thereby causing the rotating ring 2533 arranged on the driving end of the agitation pump 2532 to rotate, and finally causing the agitation blade 2531 fixedly connected to the rotating ring 2533 to rotate. When the agitation blade 2531 rotates, the cleaning liquid in the detection chamber 222 can be stirred, thereby improving the cleaning effect of the cleaning liquid.

[0038] Reference Figure 6-Figure 8A pushing device 26 is provided at the end of the sugar content detector 21. After the cleaning cavity 221 or the detection cavity 222 is completely formed, the pushing device 26 pushes the sugar content detector 21 into the detection shell 22. When the sliding block 23 is in a sliding state, the pushing device 26 drives the sugar content detector 21 to withdraw from the detection cavity 222.

[0039] The pushing device 26 includes a second pump body 261 and a second shell 262. The second shell 262 is vertically fixed on the upper part of the detection shell 22, and the second shell 262 is communicated with the detection shell 22. The second pump body 261 is arranged at the end of the second shell 262. When the second pump body 261 inflates the second shell 262, the sugar content detector 21 extends into the detection shell 22, the second pump body 261 extracts the gas in the second shell 262, and the sugar content detector 21 is withdrawn from the detection shell 22 and slides into the second shell 262.

[0040] Reference Figure 6 A sampling tube 27 is vertically arranged in the breeding barrel 1 , a sampling port of the sampling tube 27 is located at the upper side of the sampling tube 27 , and an output end of the sampling tube 27 is connected to the detection shell 22 .

[0041] Reference Figure 6 : The upper side of the sampling tube 27 is an "n"-shaped structure, the sampling port is vertically downward, and a first switch valve 271 is provided on the sampling port.

[0042] When the yeast is cultured in liquid anaerobically using the breeding barrel 1, when the sliding block 23 slides in the detection shell 22 and forms the detection cavity 222, the gradually formed detection cavity 222 extracts sugar solution from the breeding barrel 1. Since the sugar solution is converted from a paste, there are solid impurities in the sugar solution, and there are fewer solid impurities on the upper side of the breeding barrel 1. In this way, when the upper sugar solution in the breeding barrel 1 is taken out through the sampling tube 27, it can be ensured that there are fewer solid impurities in the sugar solution, thereby reducing the filtration pressure at the filter screen 24. The upper side of the sampling tube 27 is set to an "n" shape structure, which avoids the situation where yeast, paste or amylase falls on the sampling port when being added, thereby causing the substance added to the breeding barrel 1 to fail to react smoothly.

[0043] Reference Figure 5-Figure 7 A fermentation barrel 3 is arranged on one side of the breeding barrel 1. The fermentation sleeve is connected to the breeding barrel 1. The fermentation barrel 3 is an anaerobic environment. The breeding barrel 1 transports the sugar solution and yeast reaching a preset concentration into the fermentation barrel 3.

[0044] Since yeast fermentation needs to be carried out in an anaerobic environment, when the paste and amylase are added into the breeding barrel 1, the breeding barrel 1 is no longer connected to the outside world, so that the influence of external oxygen on the yeast fermentation can be controlled to the maximum extent. Since the breeding barrel 1 is in a closed state when the liquid is anaerobic, when the yeast is added into the breeding barrel 1 at this time, even if there is a small amount of oxygen in the breeding barrel 1, it can be quickly consumed by the yeast. Since fermentation requires a certain amount of time, if the yeast and sugar solution are left in the breeding barrel 1 for fermentation, the breeding barrel 1 can no longer be used. Therefore, a fermentation barrel 3 is set on one side of the breeding barrel 1, so that the fermentation barrel 3 provides a suitable fermentation place for the yeast and the sugar solution, and also allows the breeding barrel 1 to be emptied. In this way, after the concentration of the sugar solution reaches the preset concentration, the sugar solution and yeast are all added into the fermentation barrel 3, which allows the yeast to better use the sugar solution for fermentation.

[0045] Reference Figure 5-Figure 7 An extraction tube 5 is horizontally arranged at the lower part of the sampling tube 27, a second switch valve 51 is arranged on the extraction tube 5, a reversing valve 4 is arranged at the connection between the sampling tube 27 and the detection shell 22, a delivery tube 41 connected to the fermentation barrel 3 is arranged on one side of the sugar content detection unit 2, and the reversing valve 4 can be connected to the delivery tube 41 or the sugar content detection unit 2 through reversing.

[0046] The reversing valve 4 is preferably a two-position two-way valve. The reversing valve 4 is connected to the sugar content detection unit 2 when the sugar content detection unit 2 detects the breeding barrel 1. After the sugar solution reaches a preset concentration, the reversing valve 4 is reversed and connected to the delivery pipe 41. Only when the liquid is oxygen-free and the sugar solution concentration in the breeding barrel 1 reaches a preset concentration, the second switch valve 51 is opened, the reversing valve 4 is reversed and connected to the delivery pipe 41, and a delivery pump is provided on the delivery pipe 41. The sugar solution and yeast in the breeding barrel 1 enter the fermentation barrel 3 through the delivery pipe 41. If the extraction pipe 5 is not provided, the sampling pipe 27 cannot completely extract the liquid in the breeding barrel 1. Reference Figure 1-Figure 10 The present invention also relates to a method for cultivating starch efficient conversion yeast, using a device for starch efficient conversion yeast, and the specific steps are as follows: S1. Add starch-containing paste and amylase into the breeding barrel 1. Amylase decomposes the starch in the paste into sugar solution. The sliding block 23 is now located at the end of the detection shell 22 facing the breeding barrel 1. A cleaning cavity 221 is formed on one side of the sliding block 23. The sugar content detector 21 is located in the cleaning cavity 221.

[0047] S2, the sliding block 23 moves in the detection shell 22 in the direction away from the breeding barrel 1, and the sliding block 23 gradually forms a detection cavity 222 on its side close to the breeding barrel during the movement. The sugar solution in the breeding barrel 1 is drawn into the detection cavity 222. After the detection cavity 222 is completely formed, the detection end of the sugar content detector 21 is located in the detection cavity 222, and the sugar content detector 21 detects the concentration of the sugar solution in the detection cavity 222.

[0048] S3. After the sugar content detector 21 completes the detection, the sliding block 23 moves toward the breeding barrel 1 in the detection shell 22, and the detection chamber 222 of the sliding block 23 toward the breeding barrel 1 side gradually shrinks, and the sugar solution in the detection chamber 222 is pushed back into the breeding barrel 1 by the sliding block 23. At the same time, a cleaning chamber 221 is gradually formed on the side of the sliding block 23 away from the breeding barrel 1. When the sliding block 23 reaches the end of the detection shell 22 close to the breeding barrel 1, the cleaning chamber 221 is completely formed, and cleaning liquid is injected into the cleaning chamber 221. The cleaning liquid cleans the detection end of the sugar content detection liquid in the cleaning chamber 221, and the above steps are repeated until the sugar solution concentration reaches the preset concentration, and then the activated yeast is added to the breeding barrel 1.

[0049] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
