Description

Technical Field

[0001] The present invention relates to the field of bioengineering technology, and particularly to a feeding device for preparing a compound probiotic preparation. Background Art

[0002] A compound probiotic preparation is an active preparation composed of various beneficial microorganisms or their metabolites, which is commonly used to improve the microecological balance of animals and humans and is widely applied in the fields of agriculture, aquaculture, food fermentation, and medicine. In the production process of such preparations, high requirements are imposed on the feeding process. It is not only necessary to ensure the accuracy of the types, dosages, and ratios of the added materials, but also to take into account the sealing inside the equipment and the stability of the microbial living environment to reduce the risk of external contamination.

[0003] Most of the existing feeding devices have relatively simple structures and usually adopt fixed or manual handling feeding methods. For the production of compound probiotic preparations, this method has the following problems: 1. Difficulty in ensuring feeding accuracy: Traditional devices often cannot automate or precisely adjust the feeding process, resulting in uneven distribution of materials and inaccurate ratios, which affects the quality and efficacy of the probiotic preparation.

[0004] 2. Insufficient sealing performance: Some devices lack effective sealing or isolation measures, and are prone to being contaminated by the external environment during the feeding process, or causing the leakage of microorganisms from inside the equipment, bringing potential risks to subsequent processes or the production environment.

[0005] 3. Single or non-adjustable feeding position: Common feeding devices can only feed at a fixed position or a single feeding point when facing different types or production requirements of different batches, and it is difficult to perform flexible and accurate feeding operations on various areas inside the tank.

[0006] 4. Poor stirring and mixing effects: Some feeding devices are not equipped with reliable mixing or stirring mechanisms. Even if the feeding position can be adjusted, it is difficult to efficiently stir the materials entering the tank, resulting in uneven concentration or composition distribution of the probiotic preparation in local areas. Summary of the Invention

[0007] In view of the deficiencies of the prior art, the present invention provides a feeding device for preparing a compound probiotic preparation, which can flexibly adjust the feeding position and feeding amount according to requirements, and has good sealing performance and stirring and mixing functions, so as to meet the requirements for material accuracy, efficient mixing, and environmental control, and further improve the stability and production efficiency of the preparation.

The feeding position adjustment mechanism is used to adjust the height and angle of the discharging control mechanism. The discharging control mechanism includes a connecting plate. On the top of the connecting plate, a material pipe is arranged. On the top of the material pipe, a storage barrel is fixed. The storage barrel is used to store the materials to be added; On the top of the tank body, a feeding gate control mechanism is fixed. The feeding gate control mechanism includes a top cover. The top cover seals the top of the tank body. On the upper surface of the top cover, an aggregate plate with a large upper part and a small lower part is arranged. Feed holes are evenly opened on the surface of the top cover.

[0009] Furthermore, a discharging pipe is connected to the bottom of the tank body. A control valve is installed inside the discharging pipe. The feeding position adjustment mechanism includes a rotating frame rotating on the surface of the tank body. On one side of the rotating frame, extension plates are arranged vertically up and down. Between the two extension plates, two track rods are vertically fixed. Between the two extension plates, a threaded rod is rotatably installed. The threaded rod is placed between the two track rods. A rotating handle is arranged at the bottom of the threaded rod.

[0010] Furthermore, lifting blocks are slidably installed on the surfaces of the two track rods. The lifting blocks are screwed on the threaded rod. The connecting plate is fixed to the outside of the lifting block by bolts.

[0011] Furthermore, the discharging port at the bottom of the material pipe corresponds to the aggregate plate. A rotating valve is installed inside the material pipe. Flow channels are opened on the surface of the rotating valve. On one side surface of the rotating valve, fixing bolts are symmetrically arranged. The fixing bolts are placed outside the material pipe.

[0012] Furthermore, a connecting bolt is fixed below the outside of the material pipe. A tension spring is connected between the connecting bolt and one of the fixing bolts. A pull rope is connected to the surface of the other fixing bolt. The pull rope vertically penetrates downward through the connecting plate.

[0013] Furthermore, a convex platform is arranged at the center of the upper surface of the top cover. The multiple feed holes are evenly distributed with the convex platform as the center. Guide cone blocks are fixed between adjacent two feed holes. Sliding grooves are evenly opened on the upper surface of the top cover. The sliding grooves are arranged inside the feed holes. A gate plate is slidably installed inside the sliding grooves. The gate plate seals the feed holes.

[0014] Further, a control ring is rotatably installed below the surface of the boss. The outer side of the control ring is evenly hinged with connecting rods, and one ends of the plurality of connecting rods away from the control ring are respectively hinged on the gate plate. The upper part of the outer side of the control ring is evenly provided with convex teeth.

[0015] Further, an extension platform is arranged on one side above the boss. The extension platform is placed above the convex teeth. A control motor is fixed on the top of the extension platform. A gear is installed downward at the output end of the control motor. The gear meshes with the convex teeth.

[0016] Further, a stirring mechanism is installed on the surface of the feeding gate plate control mechanism. The stirring mechanism includes a stirring motor fixed on the surface of the boss. A rotating shaft is installed at the output end of the stirring motor. Stirring paddles are evenly arranged on the surface of the rotating shaft. The stirring paddles are placed inside the tank body.

[0017] The present invention provides a feeding device for preparing a compound probiotic preparation. It has the following beneficial effects: Through the mutual cooperation of the feeding position adjusting mechanism and the discharging control mechanism, this device enables the feeding process to achieve precise feeding at multiple positions; the cooperation of the material pipe and the rotary valve enables the material to maintain controllable flow under different processes, and with the rotation and lifting functions of the feeding position adjusting mechanism, the operator can flexibly adjust the feeding angle; thus ensuring the accuracy of the compound probiotic preparation ratio at different stages and avoiding the difference in the activity of bacterial strains caused by uneven feeding.

[0018] This device utilizes the aggregate tray on the top cover and the sliding seal structure of the gate plate, and coordinates with the synchronous opening and closing actions of the control motor and the control ring, so that multiple feeding holes can be completely closed when not feeding; when it is necessary to feed into the tank body, the control ring and the connecting rods are driven to act through the meshing of the gear and the convex teeth, and the gate plate is synchronously opened from the feeding hole, and the rotary valve is switched to achieve fixed-point or sequential feeding; thanks to the resetting effect of the tension spring on the rotary valve and the flange seal connection between the top cover and the tank body, the external environment and the internal space are effectively isolated, thereby significantly improving the sealing performance of the overall device and reducing the risk of environmental pollution.

[0019] This device is equipped with a rotating frame and a threaded rod outside the tank body, which can realize the synchronous adjustment of the height and angle of the discharging control mechanism; the lifting block slides on the surface of the track rod and completes fine positioning through cooperation with the threaded rod, aligning the discharging port of the material pipe with the feeding holes at different positions on the surface of the top cover; since the material pipe and the storage cylinder are tightly connected to each other, the feeding path can be flexibly selected and accurate to a single feeding hole during the feeding process, meeting the requirements of multi-point feeding of the compound probiotic preparation and improving the operation flexibility during the production process.

[0020] The device is provided with a stirring mechanism on the surface of the feeding gate control mechanism, and the stirring motor drives the rotating shaft to drive the stirring paddle to rotate. After the material enters the interior of the tank body, the multi-blade structure of the stirring paddle is used to achieve rapid and uniform mixing, which helps to avoid too high or too low concentration of strains or nutrient materials in local areas. By controlling the stirring speed and duration, the mixing effect can be finely adjusted according to the strain type and the requirements of biochemical reactions, improving the mixing efficiency and stability of the compound microecological preparation, and thus ensuring the quality of the final product.

[0033] Example 2: Regarding the problem of realizing multi-point precise feeding and avoiding uneven feeding of materials through the mutual cooperation of the feeding position adjusting mechanism and the discharging control mechanism, the edible mushroom production process is selected as the object of the comparative experiment. In the experiment, the rotating handle of the feeding position adjusting mechanism adopts a manual driving rod of model "SZ-10", the threaded rod selects an M16×2 stainless steel lead screw, and the rotary valve in the discharging control mechanism selects a 304 stainless steel valve body with a valve diameter of 25mm and a flow path curve length of 20mm M16×2. Two condition groups are set in the experiment: one group is using this device (experimental group), and the other group is a traditional fixed feeding port device (control group). At the same environmental temperature Initial concentration of bacterial liquid and a liquid viscosity of 800 mPa·s, multiple comparative feedings are carried out, and the specific data are shown in Table 1.

[0034] Table 1 Comparison results of multi-point feeding uniformity test (5 sets of measured values)

[0035] Among them, the feeding deviation rate is calculated using formula (1):

[0036] From the above results, it can be seen that the feeding error of the experimental group during multi-point feeding is much lower than that of the control group, which proves that by adjusting the cooperation between the rotating handle and the discharging control mechanism, the feeding uniformity can be significantly improved, and both speed and accuracy can be taken into account.

[0037] Example 3: Regarding the problem of using the aggregate tray on the top cover surface and the gate sliding seal structure, and combining the synchronous opening and closing of the control motor and the control ring to improve the sealing performance and reduce the pollution risk, the lactic acid bacteria fermentation process was selected as the comparative test environment. The top cover of the device is a 304 stainless steel round cover with a thickness of 4 mm and an outer diameter of 400 mm, which is connected to the tank flange; the aggregate tray is made of a stainless steel drawing plate with an inner diameter of 150 mm and a height of 30 mm, and the gate is a stainless steel gate of model "GB / T 182-60". The tests were carried out under high bacterial concentration and conventional bacterial concentration CFU / mL) for comparison, and the number of times the gate is opened and the detection of external colony pollution were set as the observation indexes. The results are shown in Table 2.

[0038] Table 2 Results of the sealing performance control test (5 measurement values)

[0039] In the comparative test, the environmental temperature, humidity, operation duration, etc. were fixed control variables. The number of external pollution colonies was significantly lower than that of the control group, indicating that this device can still maintain good sealing performance after the gate is opened multiple times, reducing the activity attenuation caused by external pollution during the lactic acid bacteria fermentation process. Since there is no control equation involving specific calculations here, there are no relevant formulas.

[0040] Example 4: Regarding the function of using the combination of the rotating frame and the threaded rod to realize the multi-angle and height synchronous adjustment of the discharging control mechanism, and aligning the discharging port of the material pipe with different positions on the top cover to meet the multi-point feeding requirements, three kinds of soybean product fermentation liquid with different viscosities were selected for comparative tests. The rotating frame is made of galvanized steel plate with a thickness of 6 mm, and a high-precision angle ruler (accuracy 0.5°) is used to measure the rotation angle. The threaded rod is a ball screw with a pitch of 2 mm to reduce friction. The viscosities of the liquid were controlled at 1000 mPa·s, 1500 mPa·s and 2000 mPa·s respectively, and the feeding deviation and feeding speed at different angle adjustments were recorded. The results are shown in Table 3. The relationship between the feeding flow rate V, viscosity μ and flow channel cross-sectional area A was analyzed by formula (2):

[0041] Table 3 Influence of angle and height adjustment on feeding performance (5 measurement values)

[0042]

[0043] ​Among them, P is the constant driving force (from the pressure in the material pipe), and L is the length of the flow channel. It can be seen from the data that when the viscosity is relatively high, the adjustment angle has an obvious influence on the feeding speed and deviation rate. By means of multi-angle adjustment, the flow rate and flow direction of the material can be effectively controlled, improving the feeding accuracy and efficiency under different viscosity liquid materials.

[0044] Example 5: Aiming at the problem of setting a stirring mechanism on the surface of the feed gate control mechanism to improve the mixing efficiency by driving the stirring paddle with a stirring motor and avoiding too high or too low bacterial concentration in local areas, a solid yeast culture medium was selected for the experiment. The stirring motor uses an explosion-proof motor with a rated power of 100W and a rotation speed of 1000r / min. The number of stirring paddles is 4 and they are distributed in a double-layer spiral. Comparative test conditions: In the experimental group, the stirring mechanism was turned on and stirred for 5 minutes at different rotation speeds (300r / min, 400r / min, 500r / min, 600r / min, 700r / min); the control group was without stirring or only manually stirred. The difference in yeast concentration between the bottom and the top of the tank was measured, and the results are shown in Table 4.

[0045] Table 4 Results of the comparative test on mixing uniformity (5 groups of measured values)

[0046] Under the same external environment, in the experimental group, as the rotation speed increased, the difference in bacterial concentration between the bottom and the top decreased significantly, while in the control group, it remained at a relatively high level due to insufficient stirring. To further analyze the relationship between mixing uniformity and rotation speed, the mixing efficiency E can be defined by formula (3):

[0047] Among them, is the average measured bacterial concentration in the whole tank of culture medium, and are the bacterial concentration values at the top and the bottom respectively. Through comparative calculation, the high rotation speed of the stirring motor significantly improves the mixing efficiency, proving that this device can effectively reduce the local bacterial concentration difference during the preparation of the compound probiotic preparation and achieve a fast and uniform mixing effect.

[0048] Working principle: When in use, first rotate the handle 25 to control the rotation of the threaded rod 24, and then control the height of the lifting block 26 and the feeding control mechanism 3. Lower the feeding control mechanism 3 to the bottom, and pour the weighed material into the interior of the storage cylinder 33 for easy feeding. After the initial feeding is completed, control the feeding control mechanism 3 to move up to the highest position. At this time, the outlet of the material pipe 32 is higher than the aggregate tray 42, and the outside of the aggregate tray 42 is closely attached to the connecting plate 31 to prevent leakage of the added material. Due to the existence of the tension spring 38, the rotary valve 34 is in a fixed angle when not under force to remain closed. Rotating the rotary frame 21 can control the position of the feeding control mechanism 3 to adjust the relative position of the feeding.

[0049] When feeding, start the control motor 410 to drive the gear 411 to rotate. Through the meshing of the gear 411 and the convex teeth 481, the control ring 48 rotates. When the control ring 48 rotates, multiple link rods 49 on its surface synchronously control the movement of multiple gate plates 47, causing the gate plates 47 to slide into the interior of the chute 46. At this time, the feed holes 44 are opened for the entry of the material. After adjusting the angle of the rotary frame 21, pull down the pull rope 37 to control the rotation of the rotary valve 34, making the flow channel 35 tend to be vertical. At this time, the material inside the storage cylinder 33 flows into the material pipe 32 through the flow channel 35, and then flows into the inner side of the aggregate tray 42. Through the inclined surface of the inner wall of the aggregate tray 42, the material will flow into the feed holes 44 and then into the interior of the tank body 13 to achieve fixed-point feeding. The guiding cone block 45 can isolate adjacent feed holes 44 to guide and separate the material when it flows into the aggregate tray 42. According to the detection of various sensors inside the tank body 13, the feeding work is carried out in a single area inside the tank body 13 to ensure the uniformity and balance of the internal microecology. It is also possible to separately feed different feed holes 44 in sequence to expand the feeding area for easy mixing. After the feeding is completed, control the gate plate 47 to seal the feed holes 44 through the control motor 410 to ensure that the tank body 13 is in a sealed state, reducing the influence of the outside on the internal microorganisms. At the same time, a stirring mechanism 5 is also equipped. The stirring motor 51 can drive the stirring paddle 53 to rotate to achieve stirring and mixing of the internal material.

[0050] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
