Description

Technical Field

[0001] The present invention belongs to the technical field of yeast production, and particularly relates to a rolling layered yeast extract dehydration and drying device. Background Art

[0002] During the production process of yeast, steps such as batching, sterilization, concentration, dehydration and drying are required. When performing dehydration and drying, it is necessary to heat and dehydrate the concentrated yeast liquid that has undergone concentration treatment to form solid crystals of yeast.

[0003] After retrieval, a patent document with the publication number CN221570956U, publication date of August 20, 2024, and titled "A Sterilizable Yeast Hydrolysate Concentration and Drying Device" is cited. It includes a box body. A moving hole larger than the diameter of the discharge pipe is opened on the right side of the box body. By setting the moving hole, sufficient moving space can be left when the discharge pipe is driven to move up and down, and there will be no interference with the right side wall of the box body. A collection box is fixed on the right side of the top of the box body. The top of the box body is fixed with a feed port penetrating into the inner cavity of the box body. Horizontal plates are fixed on the front and rear side walls of the inner cavity of the box body. In the above embodiment, the limiting component is moved upward by the rebounding force of the connecting spring, so that the aggregate bin is driven to shake. When the yeast hydrolysate is shaken, it keeps tumbling, so that the yeast hydrolysate is evenly heated and sterilized, achieving the purpose of good sterilization effect.

[0004] However, the above embodiment still has the following defects:

[0005] The aggregate bin used to drive the yeast hydrolysate to shake in the above embodiment can only achieve vertical movement, and its movement direction is single. A large area of the inner wall of the aggregate bin cannot contact the yeast hydrolysate, which makes the impact forces received by each area in the aggregate bin different. After long-term use, due to the inconsistent external forces suffered, the wear degree and oxidation degree of each area of the aggregate bin are also different, resulting in inconvenient later maintenance and also reducing the service life of the component that drives the movement of the yeast hydrolysate, that is, the aggregate bin.

[0018] The beneficial effects of the present invention are:

[0019] 1. By setting the spiral stirring rod to a spiral and inverted cone structure, a vortex is formed when the fermentation concentrate is stirred and heated to increase the centrifugal force and avoid precipitation and adhesion to the inner wall. At the same time, the vortex is also used to concentrate the fermentation concentrate to the pipette at the center, thereby improving the smoothness of feeding. In addition, the lower pressure ring is always flush with the liquid level when it descends through the second liquid level sensor, and the spiral stirring rod is squeezed when it descends, so that the spiral stirring rod is longitudinally compressed, and the spiral stirring rod is always located below the liquid level of the fermentation concentrate without affecting the stirring work. The resistance encountered during rotation and the contact time with the liquid are always kept the same. Compared with the stirring parts of the traditional drying device, it has a longer service life and is also convenient for overall maintenance in the later stage.

[0020] 2. After secondary heating, the yeast concentrate falls onto the lower liquid net at the bottom of the circulation drum. The yeast extract that has been dried and condensed into crystals is intercepted by the lower liquid net, and then slides down along the inclination of the circulation drum into the finished product tank, and then is discharged through the discharge port. The yeast concentrate that has not yet condensed falls back into the drying tank through the lower liquid net, and waits for secondary heating again, so that the yeast concentrate is heated once and twice during rolling, and the crystals and the yeast extract that has not yet crystallized are separated, and the finished product is collected and reheated in layers, so that the drying is more thorough.

[0021] 3. After entering the loop cylinder, the yeast concentrate contacts the extension rods of each group. Since the cross-section of the port of the shunt groove is a fan-shaped ring structure, when the yeast concentrate contacts the extension rods, it will be evenly divided into two groups and move along the fan-shaped ring paths of the two groups of shunt grooves respectively. Under the action of inertia, the yeast concentrate tumbles to form a vortex and then falls again to contact the extension rods, thus ensuring that the yeast concentrate increases its contact times with the heat source during movement, thereby improving the heating intensity.

[0022] 4. The push plate is controlled to push the yeast concentrate in the liquid accumulation pool into the range of the liquid homogenizing plate. Since the height of the anti-overflow arc angle on the side closer to the central axis of the liquid accumulation pool is higher than that at the edge, the yeast concentrate will not flow back into the liquid accumulation pool and enters the corresponding drying tanks of each group through the liquid inlet ports of the first electromagnetic valves, achieving independent feeding for each drying tank. Together with the independent transportation of the raw material tank to each liquid accumulation pool, the function of separating the fermented concentrate into several environments for drying simultaneously is realized, making the drying work faster and enabling each drying tank to independently carry out the feeding work according to the progress of its own drying work.

Detailed implementation manners

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] The embodiments of the present invention provide a rolling stratified yeast extract dehydration and drying device. Exemplarily, such as Figure 1As shown, it includes a raw material tank 100, and several groups of liquid control units 200 are distributed in a circular array around the raw material tank 100. A sealing cover 201 is provided at the top of each group of the liquid control units 200. A feeding pipe 110 is communicated with each sealing cover 201, and one end of each feeding pipe 110 away from the sealing cover 201 is communicated with the output end of the raw material tank 100.

[0038] Exemplarily, several groups of drying modules 300 are distributed in a circular array at the top peripheral edge of each group of the liquid control units 200. The input end of each group of the drying modules 300 is communicated with the cavity of the corresponding group of the liquid control units 200. The liquid control unit 200 is used to control the quantity of the yeast concentrate in each group of the drying modules 300.

[0039] Exemplarily, as Figure 2 and Figure 3 shown, the drying module 300 includes a drying tank 310. A liquid inlet 311 is provided on a side wall of the drying tank 310 close to the liquid control unit 200, and a first electromagnetic valve is provided on the liquid inlet 311. A second electric push rod 320 is installed vertically on the inner wall at the top of the drying tank 310. A lifting ring is provided at the bottom of the second electric push rod 320, and a pressing unit 330 is provided directly below the lifting ring.

[0040] Exemplarily, several groups of inclined rods 321 are distributed in a circular array on the peripheral side walls of the lifting ring. The bottom of the inclined rods 321 extends obliquely away from the central axis of the lifting ring and is installed on the top of the pressing unit 330.

[0041] Exemplarily, a servo motor 340 is installed at the center of the bottom of the drying tank 310. The output end of the servo motor 340 extends into the drying tank 310 and is drivingly connected with a spiral stirring rod 360.

[0042] Exemplarily, a liquid suction pipe 350 is provided vertically on the central axis of the drying tank 310. The pressing unit 330 is slidably sleeved on the outer wall of the liquid suction pipe 350, and several groups of pull rods with the same number as the inclined rods 321 are distributed in a circular array at the top of the liquid suction pipe 350. The top of each group of the pull rods is installed on the corresponding group of the inclined rods 321. A liquid suction port is provided on the side wall of the liquid suction pipe 350.

[0043] Exemplarily, several groups of circulation units 400 are communicated with the top peripheral edge of the liquid suction pipe 350, and the several groups of the circulation units 400 are arranged in a circular array.

[0044] Specifically, a first liquid level sensor is provided on the inner wall of the drying tank 310.

[0045] When the liquid level of the yeast concentrate in the drying tank 310 is lower than the first liquid level sensor, a signal is sent to the liquid control unit 200 through the first liquid level sensor. The yeast concentrate is transported into the drying tank 310 through the liquid control unit 200. The yeast concentrate is heated once in the drying tank 310, and then the yeast concentrate after the first heating is transported into each group of circulation units 400 through the liquid suction pipe 350. The yeast concentrate is heated twice through the circulation unit 400 to finally form crystals, thus achieving the purpose of dehydration and drying.

[0046] Exemplarily, as Figure 4 and Figure 5 shown, the liquid control unit 200 includes a liquid control tank 210. A liquid accumulation pool 211 is provided at the center of the top of the liquid control tank 210. The sealing cover 201 is movably installed on the top of the liquid accumulation pool 211. A first electric push rod 240 is installed at the bottom of the liquid accumulation pool 211. The top of the first electric push rod 240 is drivingly connected to a liquid pushing plate 220. A sealing ring 221 is sleeved on the peripheral side wall of the liquid pushing plate 220. The outer wall of the sealing ring 221 is slidably attached to the inner wall of the liquid accumulation pool 211. The edge of the top opening of the liquid accumulation pool 211 is provided with an anti-overflow arc angle 212. The height of the anti-overflow arc angle 212 on the side closer to the central axis of the liquid accumulation pool 211 is higher than that on the other side.

[0047] Exemplarily, a liquid homogenizing plate 230 with a horn-shaped structure is sleeved on the anti-overflow arc angle 212. A plurality of groups of liquid discharge ports 231 with the same number as the drying modules 300 are annularly and arrayedly distributed on the side wall of the liquid homogenizing plate 230. The output end of each group of liquid discharge ports 231 is communicated with a corresponding group of liquid inlet ports 311.

[0048] First, control the first electric push rod 240 to control the liquid pushing plate 220 to rise, and push the yeast concentrate in the liquid accumulation pool 211 to the range of the liquid homogenizing plate 230. Since the height of the anti-overflow arc angle 212 on the side closer to the central axis of the liquid accumulation pool 211 is higher than that at the edge, after the yeast concentrate enters the range of the liquid homogenizing plate 230, it will no longer flow back into the liquid accumulation pool 211, and enters the corresponding groups of drying tanks 310 through the liquid inlet ports 311 of each group where the first electromagnetic valve is opened, achieving independent feeding for each group of drying tanks 310. Coupled with the independent transportation of the raw material tank 100 to each group of liquid accumulation pools 211 respectively, the function of separating the fermentation concentrate into several environments for simultaneous drying is realized, making the drying work faster, and also enabling each group of drying tanks 310 to independently carry out the feeding work according to the progress of their own drying work.

[0049] Exemplarily, 6 and Figure 7As shown, the pressing unit 330 includes a pressing ring 331, and the central axis of the pressing ring 331 coincides with the central axis of the drying tank 310. The bottoms of several groups of the inclined rods 321 are annularly and arrayedly installed at the four peripheral edges of the top of the pressing ring 331. An elevating collar 332 is provided on the central axis of the pressing ring 331, and the elevating collar 332 is slidably sleeved on the liquid suction pipe 350. One ends of several groups of cross rods 333 are annularly and arrayedly distributed on the peripheral side walls of the elevating collar 332, and the other ends of the cross rods 333 are installed on the inner wall of the pressing ring 331. A second liquid level sensor is provided on the pressing ring 331.

[0050] Exemplarily, a sealed bearing seat 334 is rotatably connected to the bottom of the pressing unit 330, and the bottom of the sealed bearing seat 334 is rotatably connected to the spiral stirring rod 360. The spiral stirring rod 360 includes several groups of bent rods arranged at equal intervals along a spiral path, and the bottom diameter of the spiral stirring rod 360 is smaller than the top diameter. A set of return springs 361 are connected between adjacent two groups of the bent rods.

[0051] After the liquid level of the fermentation concentrate in the drying tank 310 reaches the height of the second liquid level sensor, the temperature in the drying tank 310 is heated to 60 °C, and then the servo motor 340 is started. The spiral stirring rod 360 is driven by the servo motor 340 to rotate as a whole. Since the spiral stirring rod 360 is a spiral structure as a whole and the bottom diameter is smaller than the top diameter, this makes the spiral stirring rod 360 form an inverted conical structure as a whole. Then, through the rotation of the spiral stirring rod 360, the fermentation concentrate in the drying tank 310 is stirred and heated while forming a vortex, so as to increase the centrifugal force, avoid precipitation and adhesion to the inner wall of the drying tank 310, and at the same time use the vortex to make the fermentation concentrate concentrate towards the liquid suction pipe 350 at the center, thereby improving the feeding smoothness.

[0052] As the drying work continues, the liquid level of the fermentation concentrate begins to drop. When the second liquid level sensor fails to detect the liquid, a signal will be sent to the second electric push rod 320, and the pressing unit 330 will be driven to descend as a whole through the second electric push rod 320 until the pressing ring 331 is flush with the liquid level. During the descent of the pressing ring 331, the spiral stirring rod 360 will be squeezed. Since the bottom of the spiral stirring rod 360 is connected to the output end of the servo motor 340 and several groups of return springs 361 are arranged at equal intervals on the spiral stirring rod 360, the spiral stirring rod 360 will be longitudinally compressed due to the extrusion, and the spiral stirring rod 360 will always be located below the liquid level of the fermentation concentrate as a whole without affecting the stirring work. This makes the resistance and the contact time with the liquid that the spiral stirring rod 360 receives during rotation always remain the same, and also makes the spiral stirring rod 360 have a longer service life compared with the stirring components of traditional drying devices and is also convenient for later overall maintenance.

[0053] Exemplarily, such as Figure 8 、 Figure 9 and Figure 10 As shown, the circulation unit 400 includes a liquid extraction pump 410. The input end of the liquid extraction pump 410 is connected to a liquid suction pipe 350, and the output end of the liquid extraction pump 410 communicates with a circulation cylinder 420. The circulation cylinder 420 is inclined, and the height of the end close to the liquid extraction pump 410 is higher than that of the other end. The end of the circulation cylinder 420 far from the liquid extraction pump 410 communicates with a second solenoid valve. The output end of the second solenoid valve communicates with a finished product tank 460. The top of the finished product tank 460 is provided with a discharge port 461. The top of the discharge port 461 communicates with a material extraction pipe, and the top of the material extraction pipe extends outside the drying tank 310 through a group of hoses. A liquid downcomer screen 430 is provided at the bottom of the circulation cylinder 420.

[0054] Exemplarily, a heat medium pipe 440 is provided on the central axis of the circulation cylinder 420. A number of groups of extension components are arranged at equal intervals on the heat medium pipe 440. The extension components include a number of groups of extension rods 450 arranged in an annular array. The cavity of the extension rod 450 communicates with the cavity of the heat medium pipe 440. A number of groups of flow dividing grooves 451 are arranged in an annular array on the extension rod 450. The port cross-section of the flow dividing groove 451 is a fan-shaped ring structure. An exhaust port 421 is opened at the top of the circulation cylinder 420. The output end of the exhaust port 421 extends outside the drying tank 310 through a group of hoses.

[0055] Preferably, a heating device is provided on one side of the liquid control unit 200. The output end of the heating device communicates with the cavities of each drying tank 310 and the cavities of each heat medium pipe 440 respectively.

[0056] Heat medium is conveyed into the heat medium pipe 440 and each group of extension rods 450 through a heating device, and the temperature of the extension rods 450 is heated to 400 °C. Then, the yeast concentrate after the first heating is conveyed into the circulation cylinder 420 through the liquid suction pipe 350 by the liquid pumping pump 410. After entering the circulation cylinder 420, the yeast concentrate contacts each group of extension rods 450. Since the port cross-section of the shunt groove 451 is a fan-shaped ring structure, when the yeast concentrate contacts the extension rods 450, it will be evenly divided into two groups and move along the fan-shaped ring paths of the two groups of shunt grooves 451 respectively. Under the action of inertia, the yeast concentrate tumbles to form a vortex and then falls again to contact the extension rods 450, thus ensuring that the yeast concentrate increases the number of times it contacts the heat source during movement, making the heating more thorough. Until the inertia decays and it falls onto the liquid discharge net 430 at the bottom of the circulation cylinder 420, the yeast extract that has been dried and condensed into crystals is intercepted by the liquid discharge net 430, and then slides down along the inclination angle of the circulation cylinder 420 into the finished product tank 460, and is then discharged through the discharge port 461. The uncondensed yeast concentrate then falls back into the drying tank 310 through the liquid discharge net 430, waiting to be reheated for the second time, so that the yeast concentrate realizes the first heating and the second heating during rolling, and by separating the crystals and the uncrystallized yeast extract, the hierarchical treatment of finished product collection and re-secondary heating is carried out, making the drying more thorough.

[0057] The above embodiments have the following beneficial effects:

[0058] 1. By setting the spiral stirring rod 360 as a spiral and an inverted conical structure, when the fermentation concentrate is stirred and heated, a vortex is formed to increase the centrifugal force, avoid precipitation and adhesion to the inner wall, and at the same time, the vortex is used to make the fermentation concentrate concentrate towards the liquid suction pipe 350 at the center, thereby improving the smoothness of feeding. Moreover, through the second liquid level sensor, the pressing ring 331 is lowered to always be flush with the liquid level, and when it descends, it squeezes the spiral stirring rod 360, causing the spiral stirring rod 360 to be longitudinally compressed, and making the spiral stirring rod 360 always located below the liquid level of the fermentation concentrate without affecting the stirring work. The resistance it receives during rotation and the contact time with the liquid also remain the same all the time. Compared with the stirring components of traditional drying devices, it has a longer service life and is also convenient for later overall maintenance.

[0059] 2. After the yeast concentrate is reheated for the second time, it falls onto the lower liquid mesh 430 at the bottom of the circulation cylinder 420. The yeast extract that has been dried and condensed into crystals is intercepted by the lower liquid mesh 430, and then slides down along the inclined angle of the circulation cylinder 420 into the finished product tank 460, and is then discharged through the discharge port 461. The yeast concentrate that has not yet condensed falls back into the drying tank 310 through the lower liquid mesh 430, waiting to be reheated for the second time, so that the yeast concentrate is heated for the first time and the second time during rolling, and by separating the crystals and the yeast extract that has not yet crystallized, the finished product collection and the hierarchical treatment of reheating for the second time are carried out, making the drying more thorough.

[0060] 3. After entering the circulation cylinder 420, the yeast concentrate contacts the groups of extension rods 450. Since the cross-section of the port of the diversion groove 451 is a fan-shaped ring structure, when the yeast concentrate contacts the extension rods 450, it will be evenly divided into two groups and move along the fan-shaped ring paths of the two groups of diversion grooves 451 respectively. Under the action of inertia, the yeast concentrate tumbles to form a vortex and then falls again to contact the extension rods 450, thereby ensuring that the yeast concentrate increases its contact times with the heat source during movement, and thus improving the heating intensity.

[0061] 4. By controlling the liquid pushing plate 220, the yeast concentrate in the liquid accumulation pool 211 is pushed into the range of the liquid homogenizing plate 230. Since the height of the anti-overflow arc angle 212 on the side closer to the central axis of the liquid accumulation pool 211 is higher than the height at the edge, the yeast concentrate will not flow back into the liquid accumulation pool 211, and enters the corresponding groups of drying tanks 310 through the liquid inlet ports 311 of each group of the first electromagnetic valves, achieving independent feeding for each group of drying tanks 310. Together with the independent delivery of the raw material tank 100 to each liquid accumulation pool 211, the function of separating the fermentation concentrate into several environments for drying simultaneously is realized, making the drying work faster, and also enabling each group of drying tanks 310 to independently carry out the feeding work according to the progress of their own drying work.

[0062] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
