Description

Technical Field

[0001] The 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] The yeast production process has to go through steps such as batching, sterilization, concentration, dehydration and drying. During the dehydration process, the concentrated yeast concentrate needs to be heated and dehydrated to form solid crystals of yeast.

[0003] After searching, the cited announcement number is CN221570956U, and the announcement date is August 20, 2024. The patent document is named a sterilizable yeast hydrolyzate concentration and drying device, which includes a box body, and a movable hole larger than the diameter of the discharge pipe is opened on the right side of the box body. By setting the movable hole, sufficient activity space can be left when the discharge pipe is driven to move up and down, and it will not interfere 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, and a feed port that penetrates the inner cavity of the box body is fixed on the top of the box body. The front and rear side walls of the inner cavity of the box body are fixed with horizontal plates. The above embodiment moves the limit assembly upward by connecting the rebound force of the spring, so that the collection bin is driven to shake, and the yeast hydrolyzate keeps rolling when it is shaken, so that the yeast hydrolyzate is evenly heated and sterilized, achieving the purpose of good sterilization effect.

[0004] However, the above embodiment still has the following defects: The above-mentioned embodiment is used to drive the yeast hydrolyzate to shake the collection bin which can only realize vertical movement, and its movement direction is single. A large area of ​​the inner wall of the collection bin cannot contact the yeast hydrolyzate, which makes the impact force on each area in the collection bin different. After long-term use, due to the different external forces, the wear and oxidation degree of each area of ​​the collection bin are also different, which makes the later maintenance inconvenient and also reduces the service life of the component that drives the yeast hydrolyzate to move, namely, the collection bin.

[0015] The beneficial effects of the present invention are: 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.

[0016] 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.

[0017] 3. After entering the circulation cylinder, the yeast concentrate contacts each group of extension rods. Since the port cross-section of the diversion trough is a fan-shaped structure, the yeast concentrate will be evenly divided into two groups after contacting the extension rods, and move along the fan-shaped paths of the two groups of diversion troughs respectively. Under the action of inertia, the yeast concentrate rolls to form a vortex and falls again to contact the extension rods, thereby ensuring that the yeast concentrate increases the number of contacts with the heat source during movement, thereby increasing the heating intensity.

[0018] 4. The yeast concentrate in the liquid pool is pushed into the range of the liquid homogenizing plate by controlling the liquid push plate. Since the height of the anti-overflow arc angle close to the central axis of the liquid pool is higher than the height at the edge, the yeast concentrate will not flow back into the liquid pool, and enter the corresponding drying tanks by opening the liquid inlet of each group of the first solenoid valve, so that each group of drying tanks can be independently loaded. In combination with the independent transportation of each group of liquid pools by the raw material tank, the fermentation concentrate can be separated into several environments for simultaneous drying, which makes the drying work faster and allows each group of drying tanks to independently load materials according to the progress of their own drying work.

[0019] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or understood by practicing the present invention.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The present invention provides a rolling layered yeast extract dehydration drying device, which is exemplified as follows: Figure 1As shown, it includes a raw material tank 100, and a plurality of groups of liquid control units 200 are distributed in a circular array around the raw material tank 100. A group of sealing covers 201 are provided on the top of each group of liquid control units 200. A group of material delivery pipes 110 are connected to each group of sealing covers 201, and one end of each group of material delivery pipes 110 away from the sealing cover 201 is connected to the output end of the raw material tank 100.

[0034] Exemplarily, a plurality of drying modules 300 are distributed in a circular array around the top edge of each group of the liquid control unit 200, and the input end of each group of the drying module 300 is connected to the cavity of the corresponding group of the liquid control unit 200. The liquid control unit 200 is used to control the amount of yeast concentrate in each group of the drying module 300.

[0035] For example, Figure 2 and Figure 3 As shown, the drying module 300 includes a drying tank 310, and 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 solenoid valve is provided on the liquid inlet 311. A second electric push rod 320 is vertically mounted on the inner wall of the top of the drying tank 310, and 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.

[0036] Exemplarily, a plurality of groups of inclined rods 321 are distributed in a circular array on the side walls around the lifting ring. The bottom of the inclined rods 321 extends obliquely toward a side away from the central axis of the lifting ring and is installed on the top of the pressing unit 330 .

[0037] Exemplarily, a servo motor 340 is installed at the bottom center of the drying tank 310 , and an output end of the servo motor 340 extends into the drying tank 310 and is transmission-connected to a spiral stirring rod 360 .

[0038] Exemplarily, a liquid suction pipe 350 is provided on the central axis of the drying tank 310 in a vertical direction, the pressing unit 330 is slidably sleeved on the outer wall of the liquid suction pipe 350, and a plurality of groups of tie rods having the same number as the inclined rods 321 are distributed in a circular array on the top of the liquid suction pipe 350, and the top of each group of tie rods is installed on a corresponding group of inclined rods 321. A liquid suction port is provided on the side wall of the liquid suction pipe 350.

[0039] Exemplarily, the top edges of the pipette 350 are connected to a plurality of circulation units 400 , and the plurality of circulation units 400 are arranged in a ring array.

[0040] Specifically, a first liquid level sensor is disposed on the inner wall of the drying tank 310 .

[0041] 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, and the yeast concentrate is transported to the drying tank 310 through the liquid control unit 200. The yeast concentrate is heated once by the drying tank 310, and then the yeast concentrate after the heating is transported to each group of circulation units 400 through the pipette 350. The yeast concentrate is heated twice by the circulation unit 400 to finally form crystals, thereby achieving the purpose of dehydration and drying.

[0042] For example, Figure 4 and Figure 5 As shown, the liquid control unit 200 includes a liquid control tank 210, a liquid accumulation pool 211 is provided at the top center of the liquid control tank 210, and 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, and a liquid push plate 220 is connected to the top of the first electric push rod 240. A sealing ring 221 is sleeved on the side walls around the liquid push plate 220, and the outer wall of the sealing ring 221 is slidably fitted with the inner wall of the liquid accumulation pool 211. The edge of the top opening of the liquid accumulation pool 211 is set as an anti-overflow angle 212, and the height of the anti-overflow angle 212 close to the central axis of the liquid accumulation pool 211 is higher than the height of the other side.

[0043] Exemplarily, a trumpet-shaped liquid uniformizing plate 230 is sleeved on the anti-arc overflow corner 212, and a number of groups of liquid discharge ports 231 equal in number to the drying module 300 are distributed in a circular array on the side wall of the liquid uniformizing plate 230, and the output end of each group of liquid discharge ports 231 is connected to a corresponding group of liquid inlets 311.

[0044] First, the first electric push rod 240 is controlled to control the liquid push plate 220 to rise, and the yeast concentrate in the liquid pool 211 is pushed into the range of the liquid homogenizing plate 230. Since the height of the anti-overflow arc angle 212 close to the central axis of the liquid pool 211 is higher than the height at the edge, the yeast concentrate will not flow back into the liquid pool 211 after entering the range of the liquid homogenizing plate 230, and enters the corresponding drying tanks 310 through the opening of the first electromagnetic valve. The liquid inlet 311 of each group, so that each group of drying tanks 310 is independently loaded. In addition, the raw material tank 100 can be independently transported to each group of liquid pools 211, realizing the function of separating the fermentation concentrate into several environments for simultaneous drying, making the drying work faster, and also allowing each group of drying tanks 310 to independently load according to the progress of its own drying work.

[0045] For example, 6 and Figure 7As shown, the lower pressing unit 330 includes a lower pressing ring 331, and the central axis of the lower pressing ring 331 coincides with the central axis of the drying tank 310. The bottoms of several groups of the inclined rods 321 are installed in a circular array at the edges of the top of the lower pressing ring 331. A lifting ring 332 is provided on the central axis of the lower pressing ring 331, and the lifting ring 332 is slidably sleeved on the liquid suction tube 350. One ends of several groups of cross bars 333 are distributed in a circular array on the side walls around the lifting ring 332, and the other ends of the cross bars 333 are installed on the inner wall of the lower pressing ring 331. A second liquid level sensor is provided on the lower pressing ring 331.

[0046] Exemplarily, the bottom of the pressing unit 330 is rotatably connected to a sealed bearing seat 334, and the bottom of the sealed bearing seat 334 is rotatably connected to a spiral stirring rod 360. The spiral stirring rod 360 includes a plurality of groups of curved 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 group of return springs 361 are connected between two adjacent groups of curved rods.

[0047] 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, the spiral stirring rod 360 forms an inverted cone 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, and a vortex is formed to increase the centrifugal force to avoid precipitation and adhesion to the inner wall of the drying tank 310. At the same time, the vortex is also used to concentrate the fermentation concentrate to the pipette 350 at the center, thereby improving the smoothness of feeding.

[0048] As the drying process continues, the liquid level of the fermentation concentrate begins to drop. When the second liquid level sensor cannot detect the liquid, it sends a signal to the second electric push rod 320, which drives the lower pressure unit 330 to drop as a whole, until the lower pressure ring 331 is flush with the liquid level. In the process of the lower pressure ring 331 dropping, the spiral stirring rod 360 is squeezed. Since the bottom of the spiral stirring rod 360 is connected to the output end of the servo motor 340, and there are several groups of reset springs 361 arranged at equal intervals on the spiral stirring rod 360, the spiral stirring rod 360 will be longitudinally compressed due to squeezing, and the spiral stirring rod 360 is always located below the liquid level of the fermentation concentrate without affecting the stirring work. The resistance encountered by the spiral stirring rod 360 as a whole during rotation and the contact time with the liquid are always the same, and the spiral stirring rod 360 has a longer service life than the stirring parts of the traditional drying device, and is also convenient for overall maintenance in the later stage.

[0049] For example, Figure 8 , Fig. 9 and Fig.10 As shown, the circulation unit 400 includes a liquid pump 410, the input end of the liquid pump 410 is connected to the suction pipe 350, and the output end of the liquid pump 410 is connected to a circulation cylinder 420, the circulation cylinder 420 is tilted, and the height of one end close to the liquid pump 410 is higher than the height of the other end, the end of the circulation cylinder 420 away from the liquid pump 410 is connected to a second solenoid valve, and the output end of the second solenoid valve is connected to 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 is connected to a pumping pipe, and the top of the pumping pipe extends to the outside of the drying tank 310 through a group of hoses. A lower liquid net 430 is provided at the bottom of the circulation cylinder 420.

[0050] Exemplarily, a heat medium tube 440 is provided on the central axis of the circulation cylinder 420, and a plurality of groups of extension components are arranged at equal intervals on the heat medium tube 440, and the extension components include a plurality of groups of extension rods 450 distributed in an annular array, and the cavity of the extension rods 450 is connected to the cavity of the heat medium tube 440. A plurality of group flow grooves 451 are distributed in an annular array on the extension rods 450, and the port cross section of the flow groove 451 is a fan ring structure. An exhaust port 421 is opened on the top of the circulation cylinder 420, and the output end of the exhaust port 421 extends to the outside of the drying tank 310 through a group of hoses.

[0051] Preferably, a heating device is provided on one side of the liquid control unit 200 , and the output end of the heating device is respectively connected to the cavity of each group of drying tanks 310 and the cavity of each group of heat medium pipes 440 .

[0052] The heating device delivers heat medium to the heat medium pipe 440 and each group of extension rods 450, and heats the extension rods 450 to 400°C. Then, the yeast concentrate after the primary heating is delivered to the circulation cylinder 420 through the suction pipe 350 by the liquid 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 diversion groove 451 is a fan-shaped structure, the yeast concentrate is evenly divided into two groups after contacting the extension rods 450, and moves along the fan-shaped paths of the two groups of diversion grooves 451 respectively. Under the action of inertia, the yeast concentrate rolls to form a vortex, and falls again to contact the extension rods 450, thereby ensuring that the yeast concentrate increases the number of times it contacts the heat source during movement, so that the heating is more thorough. Until it falls on the lower liquid net 430 at the bottom of the circulation drum 420 due to inertial decay, the yeast extract that has been dried and condensed into crystals is intercepted by the lower liquid net 430, and then slides along the inclined angle of the circulation drum 420 to the finished product tank 460, and then is 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 net 430 to be reheated, so that the yeast concentrate is heated once and twice during rolling, and the crystals and the yeast extract that have not yet crystallized are separated, and the finished product is collected and reheated again in a layered manner, so that the drying is more thorough.

[0053] The above embodiments have the following beneficial effects: 1. By setting the spiral stirring rod 360 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 make the fermentation concentrate concentrate to the center of the pipette 350, thereby improving the smoothness of feeding. In addition, the lower pressure ring 331 is made to descend to be flush with the liquid level through the second liquid level sensor, and the spiral stirring rod 360 is squeezed when descending, so that the spiral stirring rod 360 is longitudinally compressed, and the spiral stirring rod 360 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.

[0054] 2. After secondary heating, the yeast concentrate falls onto the lower liquid net 430 at the bottom of the circulation drum 420. The yeast extract that has been dried and condensed into crystals is intercepted by the lower liquid net 430, and then slides along the inclined angle of the circulation drum 420 into the finished product tank 460, and then is 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 net 430 to be reheated for secondary heating, 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 for stratification, so that the drying is more thorough.

[0055] 3. After entering the circulation cylinder 420, the yeast concentrate contacts each group of extension rods 450. Since the port cross-section of the diversion groove 451 is a fan-shaped structure, the yeast concentrate will be evenly divided into two groups after contacting the extension rods 450, and move along the fan-shaped paths of the two groups of diversion grooves 451 respectively. Under the action of inertia, the yeast concentrate rolls to form a vortex and falls again to contact the extension rods 450, thereby ensuring that the yeast concentrate increases the number of times it contacts the heat source during movement, thereby increasing the heating intensity.

[0056] 4. The yeast concentrate in the liquid pool 211 is pushed into the range of the liquid homogenizing plate 230 by controlling the liquid pushing plate 220. Since the height of the anti-overflow arc angle 212 close to the central axis of the liquid pool 211 is higher than the height at the edge, the yeast concentrate will not flow back into the liquid pool 211, and enters the corresponding drying tanks 310 through the opening of each group of liquid inlets 311 of the first solenoid valve, so that each group of drying tanks 310 is independently loaded. In combination with the independent delivery of each group of liquid pools 211 by the raw material tank 100, the function of separating the fermentation concentrate into several environments for simultaneous drying is realized, making the drying work faster, and also allowing each group of drying tanks 310 to independently load materials according to the progress of its own drying work.
