Description

Technical Field

[0001] The invention relates to the technical field of microbial cultivation, and in particular to a DHA plus probiotics fermentation device and a fermentation method thereof. Background Art

[0002] Bio-fermentation engineering is an important part of bio-engineering. Microorganisms use carbohydrate fermentation to produce various industrial solvents and chemical raw materials. Ethanol, acetone-butanol, butanol-isopropanol, acetone-ethanol, 2,3-butanediol and glycerol fermentation are several forms of solvent fermentation by microorganisms.

[0003] Ensure that the fermentation equipment is clean, set the appropriate fermentation temperature, adjust it according to the characteristics of the selected probiotics, adjust the pH of the culture medium to a range suitable for the growth of probiotics, mix the prepared DHA source with the culture medium, and add the probiotic strains, ensuring a uniform mix so that the probiotics can effectively contact the nutrients.

[0004] During the use of the above-mentioned DHA plus probiotics fermentation device, since the DHA plus probiotics need to be mixed and fermented, it is necessary to regularly extract fermentation samples from the fermentation tank for pH testing. After the test, the tested samples need to be returned to the fermentation tank in time. During the sampling and returning process, the samples are exposed to air or unclean objects, which may introduce miscellaneous bacteria, thereby contaminating the entire fermentation system. In addition, as the fermentation proceeds in the fermentation tank, active cells and dead cells may settle to the bottom of the tank, forming an obvious lower layer, resulting in different pH values ​​in different areas, which makes it easy for testers to make misjudgments during testing.

[0017] To achieve the above object, the present invention provides the following technical solution: a DHA plus probiotics fermentation device, comprising the following fermentation method:

[0018] S1, the output end of the motor drives the driving gear below to rotate, which will drive the meshing driven gear on one side to rotate simultaneously in the fermentation tank body. The first sliding position, the second sliding position and the third sliding position on the driven gear can respectively push the sliding tube between the lifting chute 1 and the lifting chute 2 to move up and down in the fermentation tank body, so that the sliding tube can extract fermentation samples at the upper, middle and lower positions in the fermentation tank body. When the sliding tube between the inner ring of the tank and the fermentation tank body gradually rises to the second sliding position along the arc slope on one side, it keeps horizontal and does not continue to lift upward. The sliding tube moves up along the second sliding position to the third sliding position, and the sliding tube moves along the same stroke from the first sliding position to the second sliding position. When the sliding tube is in the third sliding position, the driven gear continues to rotate, and the sliding tube slides down from the inverted hook groove to the first sliding position along the arc downslope on one side under the action of its own weight. When the sliding tube is gradually lifted along the lifting chute 2, it pushes the sliding curtain door in the lifting chute 2 to move upward to be stored in the storage groove. The lifting chute 2 under the sliding tube is blocked by the first sliding position, the second sliding position and the third sliding position on the driven gear at the same time.

[0019] S2, the driven gear drives the rotating shaft on the upper surface to rotate, and the limiting blocks on both sides of the rotating shaft can limit the sliding sleeve, driving the hot stirring plate on the sliding sleeve to rotate and stir at the same time. When the driven gear rotates in the fermentation tank body, it will drive the first sliding position, the second sliding position and the third sliding position on the driven gear to push the sliding tube to rise along the lifting slide groove 2. When the sliding tube slides and rises, the lifting frame connected to one end of the sliding tube drives the sliding sleeve to slide up and down along the rotating shaft through the limiting slide groove provided at the bottom of the sliding sleeve, and the limiting slide groove can be reciprocated up and down to the fermentation tank. The fermenter body is fully stirred, and the rotating shaft drives the exhaust turntable at the top to rotate in the fermenter body. When the connecting groove on the exhaust turntable is aligned with the exhaust hole on the sealing tank cover, if the fermentation pressure in the fermenter body increases due to fermentation, the gas will pass through the connecting groove from one end of the conical block to move upward by pushing the sealing ball at the other end, and the excess gas in the fermenter body will be intermittently discharged from the exhaust hole. The sealing ball slides upward to push the sliding column to accommodate the extrusion limit spring. When the connecting groove passes through the exhaust hole, the compressed limit spring will push the sealing ball to block the conical block under the reaction force.

[0020] S3, the controller controls the motor to drive the driving gear to rotate, so that the meshing driven gear drives the first sliding position to rotate to a lifting slide groove and stop, so that the sliding tube slides along the lifting slide groove 1 to the bottom of the fermentation tank body, and by pressing the button tube at the corresponding position on the controller, the button tube slides into the installation tube to squeeze the reset spring piece 2, and the T-shaped limit strip at one end will slide from the right end to the left end along the adjusting groove 2, pushing the moving tube at one end of the button tube to move along the T-shaped limit strip, so that the other end of the moving tube pushes the column sliding tube to slide along the fixed tube, so that the T-shaped limit strip at the other end slides from the right end to the left end of the adjusting groove 1, and the column sliding tube contacts the mouth-shaped splint in the sliding tube while moving, pushing the mouth-shaped splint to slide into the sliding tube to squeeze the reset spring piece 1, so that the pipette slides out from between the upper and lower splints, and under the action of the pressure difference, the fermentation liquid in the fermentation tank body will enter the pipette from the hose section, so that The flattened pipette expands to extract the fermentation sample. When the anti-column slide pushes the mouth-shaped splint to completely squeeze the reset spring piece 1, the folded spring piece in the mouth-shaped splint will push the extrusion block to block the extrusion of the middle hose section. The pH detector is used to test the pH of the fermentation sample extracted in the pipette. The display screen on the sealing cover can be used to observe whether the sample meets the standard. When the test is completed, the button tube is released. The compressed reset spring piece 2 and reset spring piece 1 push the button tube and the mouth-shaped splint to slide to the left at the same time under the reaction force. The button tube will drive the moving tube to pull back, so that the T-shaped limit strip at one end slides from the left end of the adjusting slot 2 to the right end again. The sliding of the mouth-shaped splint will drive the extrusion block to slide back into the mouth-shaped splint along the hypotenuse, and at the same time squeeze the pipette to transport the sample in the pipette into the fermentation tank body, and the anti-column slide is pushed by the fixed block on the mouth-shaped splint to slide to the left along the T-shaped limit strip for recovery.

[0021] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0022] 1. The rotating shaft on the upper surface is driven to rotate by the driven gear, and the sliding sleeve is driven to slide up and down along the rotating shaft and the limiting strip by the limiting slide groove provided at the bottom of the sliding sleeve and the lifting frame connected to one end of the sliding tube. The fermentation tank body can be stirred up and down, which can help to evenly distribute DHA and probiotics in the fermentation liquid, prevent them from stratification or aggregation in the container, ensure the consistency of the composition of the entire fermentation liquid, prevent the sediment generated during the fermentation process from sinking to the bottom, and avoid the sediment from affecting the overall quality of the fermentation liquid.

[0023] 2. The exhaust turntable at the top is driven to rotate in the fermentation tank body by the rotating shaft. When the connecting groove on the exhaust turntable is aligned with the exhaust hole on the sealing tank cover, the gas will pass through the connecting groove from one end of the conical block to move upward by pushing the sealing ball at the other end, and the excess gas in the fermentation tank body will be intermittently discharged from the exhaust hole. Intermittent exhaust can effectively release the accumulated carbon dioxide, prevent excessive fermentation of yeast, avoid excessive acidity or instability of the product, help control the fermentation conditions, improve fermentation efficiency, ensure product quality, and help to stabilize the management of the fermentation environment.

[0024] 3. The first sliding position, the second sliding position and the third sliding position on the driven gear can respectively push the sliding tube between the lifting chute 1 and the lifting chute 2 to move up and down in the fermentation tank body, so that the sliding tube can extract fermentation samples at the upper, middle and lower positions in the fermentation tank body. By sampling at different heights, it can be verified whether the composition distribution of the fermentation filling liquid in the entire container is uniform, which helps to ensure the consistency and quality of each bottle of product, and can identify and reduce problems caused by unevenness, thereby saving costs caused by product recalls or quality problems.

[0025] 4. By pushing the mouth-shaped clamp plate to slide into the sliding tube and squeeze the reset spring piece 1, the pipette can slide out from between the upper and lower clamp plates. Under the action of the pressure difference, the fermentation liquid in the fermentation tank body will enter the pipette from the hose section, causing the flattened pipette to expand and extract the fermentation sample. The sample can be directly extracted for testing without opening the sealed tank cover to avoid external contamination and ensure the purity of the test sample. It can save the time of opening and sealing the fermentation tank body, improve work efficiency, and keep the fermentation tank closed, which is conducive to maintaining stable fermentation conditions and improving the fermentation success rate.

[0026] 5. When the test is completed, release the button tube. Under the reaction force, the compressed reset spring piece 2 and reset spring piece 1 push the button tube and the mouth-shaped splint to slide to the left at the same time. The sliding of the mouth-shaped splint will drive the extrusion block to slide back into the mouth-shaped splint along the bevel. At the same time, it will squeeze the pipette and transport the sample in the pipette to the fermentation tank body. It can speed up the sample processing speed, reduce the manual operation time, improve the overall work efficiency, reduce the possibility of manual intervention, thereby reducing the errors caused by human operation errors and avoiding the introduction of external contaminants when the samples are put back.

A moving tube 413 is sleeved on the end of the column slide 409 away from the mouth-shaped clamp 402, and a key tube 414 is sleeved on the end of the moving tube 413 away from the column slide 409. An adjustment groove 2 415 is provided on the key tube 414. The fixed cylinder 411 is fixedly connected to the sealing cover on the fermentation tank body 100. Both ends of the T-shaped limit strip 412 are T-shaped and slide in the adjustment groove 1 410 and the adjustment groove 2 415 respectively, while limiting the column slide 409 and the key tube 414. Both ends of the moving tube 413 are limited by the key tube 414 and the fixing rings in the column slide 409 respectively.

[0058] A mounting tube 416 is sleeved on the button tube 414, one end of the T-shaped limit strip 412 is connected to a mounting block 417, a reset spring piece 418 is arranged between the mounting block 417 and the button tube 414, the mounting tube 416 is provided with a controller 419, a display screen 420 is arranged on the fermentation tank body 100, and the mounting tube 416 is clamped at one end of the controller 419. There are three mounting tubes 416, corresponding to the upper, middle and lower positions respectively. The end of the T-shaped limit strip 412 away from the fixed tube 411 is clamped in the mounting tube 416, and the two ends of the reset spring piece 418 are fixedly connected to the mounting block 417 and the button tube 414 respectively. The display screen 420 is installed on the sealing cover outside the fermentation tank body 100. The motor 212 can be controlled by the controller 419, and the position of the sliding tube 202 can also be observed.

[0059] During use, when the staff needs to detect the sample fermented at the bottom of the fermentation tank body 100, the controller 419 controls the motor 212 to drive the driving gear 211 to rotate, so that the meshing driven gear 203 drives the first sliding position 204 to rotate to the lifting slide groove 201 and stop, so that the sliding tube 202 slides along the lifting slide groove 201 to the bottom end of the fermentation tank body 100, and by pressing the button tube 414 at the corresponding position on the controller 419, the button tube 414 slides into the installation tube 416 to squeeze the reset spring piece 2 418, and the T-shaped limit strip 412 at one end will move from the right along the adjustment groove 2 415. The first end of the push button tube 414 slides to the left end, pushing the moving tube 413 at one end of the button tube 414 to move along the T-shaped limit strip 412, so that the other end of the moving tube 413 pushes the anti-pillar slide cylinder 409 to slide along the fixed cylinder 411, so that the T-shaped limit strip 412 at the other end slides from the right end of the adjustment slot 410 to the left end. The anti-pillar slide cylinder 409 contacts the mouth-shaped clamping plate 402 in the sliding tube 202 while moving, pushing the mouth-shaped clamping plate 402 to slide into the sliding tube 202 to squeeze the reset spring piece 401, so that the pipette 404 slides out from between the upper and lower clamping plates. Under the action of the pressure difference, the fermentation liquid in the fermentation tank body 100 is The pipette 404 will enter the pipette 404 from the hose section 405, so that the flattened pipette 404 will expand to extract the fermentation sample. When the column slide 409 pushes the mouth-shaped clamp 402 to completely squeeze the reset spring piece 1 401, the folded spring piece 406 in the mouth-shaped clamp 402 will push the squeeze block 407 to block the squeezing of the middle hose section 405. The pH of the fermentation sample extracted from the pipette 404 is tested by the pH detector 408. Whether the sample meets the standard can be observed through the display screen 420 on the sealing cover. When the test is completed, the button tube 414 is released, and the compressed reset spring piece 2 418 and the reset spring piece 1 Under the reaction force, 401 pushes the button tube 414 and the mouth-shaped clamp 402 to slide to the left at the same time, and the button tube 414 will drive the movable tube 413 to pull back, so that the T-shaped limit strip 412 at one end slides from the left end of the adjusting slot 2 415 to the right end again. The sliding of the mouth-shaped clamp 402 will drive the squeezing block 407 to slide along the oblique edge back into the mouth-shaped clamp 402, and at the same time squeeze the pipette 404 to transport the sample in the pipette 404 into the fermentation tank body 100, and push the column slide 409 to slide to the left along the T-shaped limit strip 412 for recovery through the fixed block 403 on the mouth-shaped clamp 402.

[0060] The remaining structure is the same as that of Example 1.

[0061] Reference Figure 1-13 , which is the fourth embodiment of the present invention, provides: a DHA plus probiotics fermentation device and a fermentation method thereof, comprising the following steps,

[0062] S1, the output end of the motor 212 drives the driving gear 211 below to rotate, which will drive the meshing driven gear 203 on one side to rotate simultaneously in the fermentation tank body 100, and the first sliding position 204, the second sliding position 205 and the third sliding position 206 on the driven gear 203 can respectively push the sliding tube 202 between the lifting chute 1 201 and the lifting chute 2 208 to lift in the fermentation tank body 100, so that the sliding tube 202 can extract fermentation samples at the upper, middle and lower positions in the fermentation tank body 100. When the sliding tube 202 between the inner ring 207 and the fermentation tank body 100 gradually rises to the second sliding position 205 along the arc slope on one side, it keeps horizontal and does not continue to lift upward, and the sliding tube The travel of the sliding tube 202 from the second sliding position 205 to the third sliding position 206 is the same as the travel from the first sliding position 204 to the second sliding position 205. When the sliding tube 202 is at the third sliding position 206, the driven gear 203 continues to rotate, and the sliding tube 202 will slide down from the hook groove to the first sliding position 204 along the arc downslope on one side under the action of its own weight. When the sliding tube 202 is gradually lifted along the lifting chute 208, it will push the sliding curtain door 209 in the lifting chute 208 to move upward to be stored in the storage groove 210. The lifting chute 208 below the sliding tube 202 will be blocked by the first sliding position 204, the second sliding position 205 and the third sliding position 206 on the driven gear 203 at the same time.

[0063] S2, the driven gear 203 drives the rotating shaft 301 on the upper surface to rotate, and the limiting blocks 302 on both sides of the rotating shaft 301 can limit the sliding sleeve 303, driving the hot stirring plate 304 on the sliding sleeve 303 to rotate and stir at the same time. When the driven gear 203 rotates in the fermentation tank body 100, it will drive the first sliding position 204, the second sliding position 205 and the third sliding position 206 on the driven gear 203 to push the sliding tube 202 to rise along the lifting groove 208. When the sliding tube 202 slides and rises, through the limiting groove 305 provided at the bottom end of the sliding sleeve 303, the lifting frame 306 connected to one end of the sliding tube 202 engages with the limiting groove 305 to drive the sliding sleeve 303 to slide up and down along the rotating shaft 301, and can reciprocate up and down to the fermentation tank body 100. The fermentation tank body 100 is fully stirred, and the rotating shaft 301 drives the exhaust turntable 307 at the top to rotate in the fermentation tank body 100 while rotating. When the connecting groove 309 provided on the exhaust turntable 307 is aligned with the exhaust hole 310 provided on the sealing tank cover 308, if the fermentation pressure in the fermentation tank body 100 increases due to fermentation, the gas will move upward from one end of the conical block 315 through the connecting groove 309 by pushing the sealing ball 313 at the other end, and the excess gas in the fermentation tank body 100 will be intermittently discharged from the exhaust hole 310. The sealing ball 313 slides upward to push the sliding column 312 to accommodate the extrusion limit spring 314. When the connecting groove 309 passes through the exhaust hole 310, the compressed limit spring 314 will push the sealing ball 313 to block the conical block 315 under the reaction force.

[0064] S3, the controller 419 controls the motor 212 to drive the driving gear 211 to rotate, so that the meshing driven gear 203 drives the first sliding position 204 to rotate to the lifting slide groove 1 201 and stop, so that the sliding tube 202 slides along the lifting slide groove 1 201 to the bottom of the fermentation tank body 100, and by pressing the button tube 414 at the corresponding position on the controller 419, the button tube 414 slides into the installation tube 416 to squeeze the reset spring piece 2 418, and the T-shaped limit strip 412 at one end will slide from the right end to the left end along the adjustment groove 2 415, pushing the moving tube at one end of the button tube 414 413 moves along the T-shaped limit strip 412, so that the other end of the movable tube 413 pushes the column slide 409 to slide along the fixed tube 411, so that the T-shaped limit strip 412 at the other end slides from the right end of the adjusting groove 410 to the left end. While moving, the column slide 409 contacts the mouth-shaped clamp 402 in the sliding tube 202, pushing the mouth-shaped clamp 402 to slide into the sliding tube 202 to squeeze the reset spring piece 401, so that the pipette 404 slides out from between the upper and lower clamps. Under the action of the pressure difference, the fermentation liquid in the fermentation tank body 100 enters the pipette from the hose section 405. 404, the flattened pipette 404 is expanded to extract the fermentation sample. When the column slide 409 pushes the mouth-shaped clamp 402 to completely squeeze the reset spring piece 1 401, the folded spring piece 406 in the mouth-shaped clamp 402 will push the squeeze block 407 to block the squeeze of the middle hose section 405. The pH detector 408 is used to detect the pH of the fermentation sample extracted from the pipette 404. The display screen 420 on the sealing cover can be used to observe whether the sample meets the standard. When the test is completed, the button tube 414 is released, and the compressed reset spring piece 2 418 and the reset spring piece 1 401 react in the reaction. Under the force, the button tube 414 and the mouth-shaped clamp 402 are pushed to slide to the left at the same time, and the button tube 414 will drive the movable tube 413 to pull back, so that the T-shaped limit strip 412 at one end slides from the left end of the adjusting slot 415 to the right end again, and the sliding of the mouth-shaped clamp 402 will drive the squeezing block 407 to slide along the hypotenuse back into the mouth-shaped clamp 402, and at the same time squeeze the pipette 404 to transport the sample in the pipette 404 into the fermentation tank body 100, and push the column slide 409 to slide to the left along the T-shaped limit strip 412 for recovery through the fixed block 403 on the mouth-shaped clamp 402.
