Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of yeast culture drying processing, in particular to a yeast culture preparation device and method for regulating the intestinal health of ruminants. BACKGROUND

[0002] Ruminants are a class of mammals with a special digestive system. In the process of evolution, they have formed a unique rumination mechanism to adapt to a diet mainly composed of grass. Meat sheep are the most common ruminants. Meat sheep farmers usually use high-concentrate diets and let the sheep graze freely. Although this feeding method can meet the fattening needs, high-concentrate diets can easily lead to impaired intestinal development in lambs, resulting in weakened digestion and absorption. In addition, high-concentrate diets can easily cause intestinal stress, leading to reduced immunity. Currently, to address the above issues, complex yeast cultures are generally added to the diet of meat sheep to improve and regulate the intestinal health of meat sheep.

[0003] Currently, the preparation process of complex yeast cultures includes the preparation of raw materials and equipment required for strain activation, strain activation and preparation of bacterial solution, strain activation and material mixing, solid-state pile fermentation, low-temperature vacuum drying, crushing and packaging, and index performance testing. Low-temperature vacuum drying is one of the most important processes in the preparation of complex yeast cultures. Compared to fluidized bed drying, it can better preserve the biological activity and physical and chemical properties of yeast, and is more suitable for the production of high-value-added and high-activity yeast products. Currently, low-temperature vacuum drying equipment is used for processing, i.e., placing the culture plate containing the culture into the drying equipment for low-temperature drying.

[0004] However, there are the following problems in the current low-temperature drying process: As the low-temperature drying process continues, the water on the surface of the yeast culture evaporates rapidly first, causing the concentration of solutes on the surface to rise suddenly and form a glassy gel film, i.e., a hard crust. The hard crust hinders the escape of internal water vapor, which can cause damage to the internal cell structure. In addition, heat transfer during the drying process is only through two ways: direct contact heat dissipation of the culture plate and exposure heat dissipation of the yeast culture surface. The internal yeast culture is difficult to dry completely, and the overall drying efficiency is low. To address this issue, manual turning of the yeast culture is used for processing. However, the turning process is hindered by the hard crust on the surface, and it is difficult for manual turning to control the turning amplitude. Large amplitude turning can easily cause damage to the cells in the yeast culture and reduce cell activity. SUMMARY

DETAILED DESCRIPTION

[0035] In order to make the above-mentioned objectives, features and advantages of the present application more apparent and easy to understand, the specific embodiments of the present application are described in detail below in conjunction with the drawings. In the following description, a large number of specific details are set forth in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the scope of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0036] As shown in Figure 1 , Figure 2 and Figure 3 , a device for preparing a yeast culture for regulating the health of the intestinal tract of a ruminant, comprising: a drying box 1, four support frames 2 arranged in a matrix are fixedly arranged in the drying box 1, a plurality of supporting plates 3 arranged equidistantly from top to bottom are fixedly arranged between the left and right two support frames 2, and the front and rear two supporting plates 3 are matched to support the same culture dish.

[0037] As shown in Figure 2 , Figure 3 and Figure 4 , a plurality of turning mechanisms 4 for turning the yeast culture are arranged in the drying box 1 in one-to-one correspondence with the culture dishes, and the turning mechanisms 4 are located above the culture dishes. The turning mechanism 4 comprises a moving frame 40, the moving frame 40 is fixedly arranged at the lower end surface of the front and rear two supporting plates 3, the electric sliding blocks 400 are slidingly arranged at the lower end surface of the moving frame 40, and the piercing roller 401 and the turning assembly 41 with their axis extending from left to right are jointly rotatably arranged on the two electric sliding blocks 400.

[0038] When the electric sliding blocks 400 move back and forth, the piercing roller 401 is first rotated to switch to the lower side and pierce the crust on the surface of the yeast culture, and then the turning assembly 41 is rotated to switch to the lower side and turn the yeast culture by a set amplitude.

[0039] AsFigure 2 and Figure 3 As shown in the figure, the turnover mechanism 4 further comprises an amplitude adjusting assembly 42 arranged on the support frame 2 and used for adjusting the piercing amplitude of the piercing roller 401 and the turnover amplitude of the turnover assembly 41.

[0040] The drying box 1 adopts a low-temperature vacuum drying mode with a drying temperature of 40-60℃.

[0041] It should be noted that the rear inner wall of the drying box 1 and the upper sealing door of the drying box 1 are provided with abutting assemblies for abutting against the culture plates. When the sealing door of the drying box 1 is closed, the front-rear position of the culture plates is limited, avoiding the problem of deviation of the position of the culture plates in the subsequent process. This part is prior art, and prior art with the same function can be replaced, which will not be described here.

[0042] In operation, first, the culture plates containing yeast culture are placed on the corresponding support plates 3 in sequence by hand, and the sealing door is closed so that the front-rear position of the culture plates is limited. Then, the drying box 1 performs low-temperature vacuum drying on the yeast culture. During the vacuum drying process, the piercing roller 401 first contacts the yeast culture, and the electric sliding block 400 drives the piercing roller 401 to move back and forth, thereby piercing the crust layer of the yeast culture, facilitating the subsequent turnover process. After the piercing operation is completed, the turnover assembly 41 is switched so that the turnover assembly 41 contacts the yeast culture, and the electric sliding block 400 moves back and forth again, thereby causing the turnover assembly 41 to slightly turn over the yeast culture, facilitating the drying escape of the water in the yeast culture and improving the drying effect of the yeast culture.

[0043] Secondly, it should be noted that before the drying operation, the piercing amplitude and the turnover amplitude are adjusted by the amplitude adjusting assembly 42 according to the thickness of the yeast culture placed in the culture plate, so as to avoid excessive piercing or turnover, which may cause damage to the cells in the yeast culture or reduce the cell activity, thereby ultimately reducing the effectiveness of the yeast culture.

[0044] Additionally, it should be noted that the set turnover amplitude and piercing amplitude are known to those skilled in the art through repeated tests, and will not cause damage to the yeast culture under the corresponding operation amplitude. In specific operation, the survival rate of live bacteria in samples of the yeast culture before and after piercing can be detected, and the appropriate turnover amplitude and piercing amplitude can be determined after repeated tests.

[0045] As shown in the figure, the left and right opposite electric sliding blocks 400 are each provided with a rotating shaft 402 penetratingly arranged thereon, the right rotating shaft 402 is connected with an output shaft of a switching motor (not shown in the figure), and the two rotating shafts 402 are each fixedly provided with a rotating frame 403. Between the left and right opposite rotating frames 403, two mounting columns 404 extending from left to right are jointly arranged. Figure 4 and Figure 5 As shown in the figure, the left and right opposite electric sliding blocks 400 are each provided with a rotating shaft 402 penetratingly arranged thereon, the right rotating shaft 402 is connected with an output shaft of a switching motor (not shown in the figure), and the two rotating shafts 402 are each fixedly provided with a rotating frame 403. Between the left and right opposite rotating frames 403, two mounting columns 404 extending from left to right are jointly arranged.

[0046] The piercing roller 401 is fixedly sleeved on the rear mounting column 404, and a plurality of piercing cones 405 are fixedly arranged on the circumferential surface of the piercing roller 401.

[0047] As shown in Figure 3 and Figure 7 , the turning assembly 41 comprises a rectangular box 410, and the rectangular box 410 is fixedly sleeved on the front mounting column 404. The turning plate 411 is slidably arranged in the rectangular box 410 through a connecting block.

[0048] The turning plate 411 is inclined forward from top to bottom and has an arc shape. The turning plate 411 is provided with sawtooth segments and solid segments. The sawtooth segments and the solid segments are arranged at intervals. The turning effect is ensured by the solid segments, and the yeast culture is combed by the sawtooth segments while ensuring that the yeast culture can leak out from the middle of the sawtooth segments, thereby avoiding the problem of yeast culture accumulation caused by turning action.

[0049] As shown in Figure 3 and Figure 5 , the rectangular box 410 is provided with a reciprocating group 44 for reciprocating movement of the turning plate 411.

[0050] As shown in Figure 3 , Figure 4 and Figure 8 , the amplitude adjusting assembly 42 comprises a sliding block 420. The sliding block 420 is arranged on the support frame 2 to slide up and down. The lifting plate 421 is fixedly arranged on the lifting plate 421. The reference bar 422 is fixedly arranged on the lifting plate 421. The mounting column 404 is attached to the reference bar 422 as the adjustment reference.

[0051] As shown in Figure 1 and Figure 8 , the support frame 2 is rotatably penetrated by a threaded rod 423 with an axis vertical to the support frame 2. The threaded rod 423 penetrates the drying box 1 at the upper end and is connected to the motor. The threaded rod 423 penetrates all the sliding blocks 420, and the threaded rod 423 is threadedly connected with the sliding blocks 420.

[0052] In operation, first, the working range is adjusted according to the thickness of the yeast culture in the culture plate, the motor drives the threaded rod 423 to rotate, and through the threaded cooperation between the threaded rod 423 and the sliding block 420 thereon, the sliding block 420 drives the corresponding lifting plate 421 to move up and down synchronously, and the positions of the lifting plate 421 and the reference bar 422 are adjusted according to the required working range. During the switching of the motor, the reference bar 422 prevents the mounting column 404 from continuing to move downward, so that the reference bar 422 serves as a reference for switching the range, and finally controls the distance between the piercing cone 405 on the piercing roller 401 and the bottom of the culture plate and the distance between the turning plate 411 and the bottom of the culture plate.

[0053] After adjusting the working range, the switching motor is operated to make the rear mounting column 404 move downward and fit the reference bar 422, at this time the piercing roller 401 is put into operation, and the electric sliding block 400 moves back and forth, and the piercing roller 401 pierces the hard shell of the yeast culture in the process of moving with the electric sliding block 400, which facilitates the evaporation of water and the subsequent turning process, and avoids the problems of direct turning, such as damage to yeast cells in the yeast culture or reduction of viable cell count.

[0054] After the piercing process, the electric sliding block 400 is reset to move to the initial rear position, and then the switching motor is operated to make the front mounting column 404 fit the reference bar 422, and then the electric sliding block 400 continues to work, driving the rectangular box 410 and the turning plate 411 to move forward. In the process of moving forward, the turning plate 411 turns the yeast culture within a set range, and the reciprocating group 44 makes the turning plate 411 move left and right in the process of moving forward, so that the sawtooth section on the turning plate 411 can comb the yeast culture, and at the same time, the yeast culture can be in contact with the sawtooth section and the solid section, avoiding the problem of continuous turning of part of the yeast culture affecting its quality. In summary, the turning of the yeast culture assists the evaporation and drying of the internal moisture, reduces the time required for drying, and improves the uniformity of drying.

[0055] As shown in Figure 4 , Figure 5 and Figure 6 , the gear 43 is fixed on the rear mounting column 404, and the rack 430 is fixed on the lifting plate 421. The rack 430 is located between the culture plate and the adjacent reference bar 422. When the rear mounting column 404 fits the upper end of the reference bar 422, the gear 43 engages with the rack 430. In order to ensure that the gear 43 can engage with the rack 430 after moving, the rear part of the upper end of the rack 430 is a flat section.

[0056] When the rear mounting column 404 contacts the reference strip 422 and the piercing operation is performed, the electric sliding block 400 starts to drive the mounting column 404 to move forward. Initially, the mounting column 404 is located on the straight section of the rack 430. As the mounting column 404 moves forward, the gear 43 gradually engages with the rack 430, so that the gear 43 drives the rear mounting column 404 to rotate synchronously through the engagement between the gear 43 and the rack 430, so that the piercing roller 401 drives the piercing cone 405 to rotate synchronously, and the hard shell on the surface of the yeast culture is pierced. It needs to be pointed out that the straight section on the rack 430 makes the rear mounting column 404 drive the gear 43 to move downward and switch, and the gear 43 gradually engages with the rack 430.

[0057] As shown in Figure 3 and Figure 7 The reciprocating group 44 includes a fixed block 440. Two fixed blocks 440 are fixedly arranged in the rectangular box 410, and the mounting column 404 penetrates the fixed block 440. The fixed block 440 and the corresponding connecting block are jointly fixedly provided with a reset spring 441.

[0058] All the connecting blocks in the same rectangular box 410 are jointly fixedly provided with a horizontal moving strip 442, which slides through the fixed block 440 and the rectangular box 410. The left end surface of the horizontal moving strip 442 is fixedly provided with an L-shaped block 443. The horizontal section of the L-shaped block 443 is a circular arc surface. The left lifting plate 421 is fixedly provided with a matching plate 444, and the right side surface of the matching plate 444 is a wave shape. Through the cooperation between the left side surface of the L-shaped block 443 and the wave-shaped side surface of the matching plate 444, the L-shaped block 443 moves left and right reciprocatingly.

[0059] When the front mounting column 404 is attached to the reference strip 422 and is ready to perform the turning operation, the electric sliding block 400 drives the mounting column 404 to move forward. During the movement of the mounting column 404, the L-shaped block 443 is kept in contact with the matching plate 444 under the action of the reset spring 441. During the movement of the L-shaped block 443 along the wave-shaped side surface of the matching plate 444, when the L-shaped block 443 moves from the trough to the peak on the matching plate 444, the reset spring 441 is compressed. The L-shaped block 443 moves rightward. When the L-shaped block 443 moves from the peak to the trough on the matching plate 444, the leftward movement of the L-shaped block 443 is reset by the elastic force generated by the reset spring 441. During the movement of the electric sliding block 400, the L-shaped block 443 drives the turning plate 411 to move left and right reciprocatingly through the horizontal moving strip 442, and the turning plate 411 turns and combs the yeast culture.

[0060] As shown in Figure 6As shown, the front side mounting column 404 is provided with a locking group 45 for controlling the direction of the turnover plate 411, the locking group 45 includes a locking strip 450, the front side mounting column 404 is fixedly provided with an L-shaped locking strip 450, the reference strip 422 is provided with a guide groove 451 at the end face of the culture plate, when the horizontal section of the locking strip 450 slides into the guide groove 451, the vertical section of the locking strip 450 maintains a vertical state.

[0061] The upper end face of the rear side part of the reference strip 422 is provided with a connection groove 452 for guiding the locking strip 450 into the guide groove 451, the front side mounting column 404 is rotated and lowered in the connection groove 452 area, and the locking strip 450 is moved into the guide groove 451.

[0062] During the piercing process, the rectangular box 410 is located above the piercing roller 401, since the front side mounting column 404 is rotationally connected with the rotating frame 403, at this time the rectangular box 410 is adaptively rotated, ensuring that the piercing roller 401 still has a lowering space during the adjustment range process, avoiding the rectangular box 410 from pushing the upper culture plate, and in summary, through the above-mentioned manner, the adjustment process that can meet the required operation range is completed in the fixed space between the adjacent culture plates, avoiding the problem of reducing the overall space utilization in the drying box 1 caused by the need to adjust the distance between the adjacent culture plates.

[0063] After the piercing operation is completed, the electric sliding block 400 is reset to the rear side initial position, the switching motor is operated to lower the front side mounting column 404 and raise the rear side mounting column 404, the front side mounting column 404 is moved to contact the upper end face of the reference strip 422, the locking strip 450 is located in the connection groove 452, and at this time the lower end face of the locking strip 450 contacts the lower side wall of the guide groove 451, at this time the rectangular box 410 is in a vertical state, with the forward movement of the electric sliding block 400, the horizontal section of the locking strip 450 enters the guide groove 451, the vertical state of the rectangular box 410 is locked through the cooperation between the guide groove 451 and the locking strip 450, ensuring that the distance between the turnover plate 411 and the yeast culture is a set distance, avoiding the problem of excessive turnover.

[0064] It needs to be explained that the appropriate size of the piercing roller 401 and the piercing cone 405 can be selected according to the length and width of the culture plate, on the basis of the size of the culture plate being determined, the volume of the yeast culture in the culture plate is also determined, under the premise of ensuring the fermentation conditions, the thickness of the hard shell is also within a certain range, if the thickness of the hard shell is different due to differences in fermentation conditions, moisture content, etc., the piercing depth can be adjusted by the adjustment assembly 42 to ensure that the yeast culture below the hard shell does not contact the piercing cone 405.

[0065] To be more precise, even if the piercing cone 405 causes damage to a small amount of yeast culture, the amount of yeast culture that the piercing cone 405 can contact on the moving path is greatly reduced compared to the existing manual turning method, and thus the impact is very small and is an acceptable loss in actual operation, which is basically negligible compared to the benefits brought by the piercing roller 401 and the piercing cone 405 to the drying efficiency.

[0066] Meanwhile, compared with the prior art, the present scheme adds a turning mechanism 4, but all are conventional ordinary mechanical structure parts, and there are no high-cost precision parts, and only one-time investment is required for long-term use, so the cost of adding the above structure is low.

[0067] In addition, the present application also provides a working method of a yeast culture preparation device for adjusting the intestinal health of ruminants, comprising the following steps: S1, adjusting the reference: manually placing the culture plates for containing yeast culture on the corresponding supporting plates 3 in turn, and adjusting the vertical height of the lifting plate 421 through the amplitude adjusting assembly 42 according to the amount of yeast culture in the culture plate, so as to adjust the piercing amplitude of the piercing roller 401 and the turning amplitude of the turning assembly 41, and then closing the drying box 1.

[0068] S2, low-temperature drying: the drying box 1 uses a low-temperature vacuum drying method with a drying temperature of 40-60°C to dry the yeast culture in all culture plates.

[0069] S3, piercing the crust layer: after a period of continuous drying, the rear mounting column 404 is lowered and attached to the reference bar 422 by switching the motor, at which time the piercing roller 401 is put into operation, and the electric sliding block 400 moves back and forth, and the piercing roller 401 pierces the hard shell of the yeast culture surface during the movement of the electric sliding block 400.

[0070] S4, turning the yeast culture: after step S3, the electric sliding block 400 is reset to the initial position on the rear side, the front mounting column 404 is attached to the reference bar 422 by switching the motor, and then the electric sliding block 400 continues to work, driving the rectangular box 410 and the turning plate 411 to move forward, and in the process of moving forward, the turning plate 411 turns the yeast culture within the set amplitude, and the reciprocating group 44 makes the turning plate 411 move left and right during the forward movement.

[0071] S5, continuous drying: after step S4, the yeast culture in the culture plate is continuously dried for a period of time, and after the drying operation is completed, all the culture plates are manually taken out.
