Description

Technical Field

[0001] This utility model relates to the field of microbial culture and fermentation technology, specifically a microbial culture and fermentation device for biological feed production. Background Technology

[0002] In the field of bio-feed production, microbial strains are the core biological agents, and their activity and purity directly affect the nutritional value and functional characteristics of feed products. Common microbial strains used in bio-feed production include, but are not limited to, Bacillus, Lactobacillus, Yeast, and Mold (such as Aspergillus oryzae). Before being put into large-scale fermentation production, microbial strains need to be expanded in high-density culture tanks. That is, through controlled culture conditions (such as temperature, pH, dissolved oxygen, and nutrient supply), a small amount of original microbial strains can be exponentially multiplied to obtain the biomass of active microorganisms that meet the needs of industrial production.

[0003] Existing culture tanks generally adopt a closed integrated structure. After the expansion culture is completed, it is very inconvenient to clean the fermentation metabolites remaining inside the culture tank and on the agitator. It is also easy to have cleaning dead corners, making it difficult to guarantee the cleaning effect of the culture tank, which in turn affects the next culture and fermentation.

[0004] Therefore, this utility model proposes a microbial culture and fermentation device for biological feed production to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a microbial culture and fermentation device for biological feed production, so as to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fermentation device for biological feed production includes a tank for containing microbial strains for fermentation and expansion. The tank is equipped with a stirring assembly. The tank is composed of two separable halves. The stirring assembly includes a rotatable insert seat on either half and a detachable shaft on the insert seat. Stirring blades are evenly distributed on the shaft. The fermentation device also includes a separation and assembly assembly for assembling and separating the two halves.

[0008] In one alternative: the insert seat is provided with a slot for insertion of the shaft end and a plurality of fasteners for fixing the shaft, and the stirring assembly further includes a drive component for driving the insert seat to rotate.

[0009] In one alternative embodiment: the splitting and joining assembly includes a base located below the tank body and two support members, the two support members being respectively connected to two halves, the base having an installation groove, the lower parts of the two support members being slidably located in the installation groove, the installation groove also having a telescopic member, the movable end of the telescopic member being hinged to the two support members with a drive rod.

[0010] In one alternative: the support member is provided with multiple reinforcing sections at equal intervals from top to bottom that are adapted to the curvature of the half body, and the ends of the reinforcing sections on the two support members are respectively provided with electromagnets and magnetic blocks.

[0011] In one alternative: the base is further provided with a liquid drop trough, and a discharge port is provided on one side of the liquid drop trough.

[0012] In one alternative: a sealing strip is provided on either of the mating sides of the two halves.

[0013] Compared with the prior art, the beneficial effects of this utility model embodiment are as follows:

[0014] After the fermentation and expansion of the microbial culture is completed, the two halves are separated by the separation and combination component. Then, the shaft and stirring blades are removed for cleaning. After the two halves are separated, their inner walls are fully exposed, making it easy to clean them. This effectively solves the problem of cleaning dead corners and ensures the cleaning effect to avoid affecting the next fermentation of the microbial culture.

Detailed Implementation

[0026] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] Please see Figures 1-3 A fermentation device for producing microbial feed includes a tank 1 for containing microbial strains for fermentation and expansion. The tank 1 is equipped with a stirring assembly 2. The tank 1 is composed of two separable halves 101. The stirring assembly 2 includes an insert seat 204 rotatably mounted on either half 101 and a detachable shaft 201 mounted on the insert seat 204. Stirring blades 202 are evenly distributed on the shaft 201. The fermentation device also includes a separation and assembly assembly 3 for assembling and separating the two halves 101.

[0028] It should be noted that the fermentation device also includes a temperature control module, a humidity control module, an aeration module, and a control module, which are existing technologies. Therefore, this application will not elaborate on the components of each module and their corresponding cooperation relationships. In addition, the tank 1 is provided with a feeding port at the top and a discharge port at the bottom.

[0029] After the fermentation and expansion of the microbial culture is completed, the two halves 101 are separated by the splitting and joining component 3. Then, the shaft 201 and the stirring blade 202 are removed for cleaning. After the two halves 101 are separated, their inner walls are fully exposed, which makes it easy to clean them, effectively solving the problem of cleaning dead corners and ensuring the cleaning effect to avoid affecting the next fermentation of the microbial culture. After cleaning, the shaft 201 and the stirring blade 202 are reinstalled and reset, and the two halves 101 are then joined together by the splitting and joining component 3 to form a complete tank 1.

[0030] Furthermore, a sealing strip 102 is provided on either of the mating sides of the two halves 101 to ensure the sealing performance when the two halves 101 are joined together.

[0031] Please see Figure 1 and Figure 4 In one embodiment of this utility model, the insert 204 is provided with a slot 205 for inserting the end of the shaft 201 and a plurality of fasteners 206 for fixing the shaft 201 (the fasteners 206 can be bolts or snap-fit ​​structures, as long as they can fix the shaft 201, and this embodiment does not limit them). The stirring assembly 2 also includes a driving component 203 for driving the insert 204 to rotate (the driving component 203 is a servo motor, geared motor, etc. in the prior art). By releasing the fastening restriction of the ends of the shaft 201 by the plurality of fasteners 206, the shaft 201 and the stirring blade 202 can be removed.

[0032] Furthermore, in this embodiment, if the insert 204 is located at the lower part of the tank 1, the bottom of the slot 205 should be provided with at least one drain groove 207. The purpose of providing the drain groove 207 is that when cleaning the half body 101, the cleaning liquid may fall into the slot 205. By providing the drain groove 207, the cleaning liquid that falls into the slot 205 can be drained out, avoiding the need for additional cleaning steps in the subsequent insert shaft 201.

[0033] Figure 1 , Figures 5-8In one embodiment of this utility model, the splitting and joining assembly 3 includes a base 301 located below the tank body 1 and two support members 302. The two support members 302 are respectively connected to two halves 101. The base 301 is provided with a mounting groove 305. The lower parts of the two support members 302 are slidably located in the mounting groove 305. The mounting groove 305 is also provided with a telescopic member 306 (the telescopic member 306 is an electric telescopic rod, hydraulic telescopic rod, etc. in the prior art). The movable end of the telescopic member 306 is hinged with a drive rod 307 between it and the two support members 302. Under the action of the two drive rods 307, the telescopic member 306 extends and retracts, causing the two support members 302 to move away from or closer to each other, thereby realizing the separation and joining of the two halves 101.

[0034] Furthermore, in this embodiment, the base 301 is provided with two sets of locking structures that lock the two support members 302 respectively (the support members 302 are locked when the two halves 101 do not need to be separated or assembled). The locking structure can be a hydraulic locking structure (with claws) in the prior art, or a brake locking structure, or others. This embodiment does not limit it. The locking structure locks the support members 302 to ensure the firmness and stability of the two halves 101 in the assembled or separated state.

[0035] Furthermore, in this embodiment, the support member 302 is provided with multiple reinforcing sections 308 at equal intervals from top to bottom, which are adapted to the curvature of the half body 101. The ends of the reinforcing sections 308 on the two support members 302 are respectively provided with electromagnets 309 and magnetic blocks 310. When the two half bodies 101 are assembled, the electromagnets 309 are energized, thereby attracting the corresponding magnetic blocks 310, ensuring the stability of the two half bodies 101 in the assembled state. Of course, the electromagnets 309 and magnetic blocks 310 can also be replaced by bolts and bolt holes. When the two half bodies 101 are assembled, the bolts are rotated to enter the corresponding bolt holes and tightened, which can also achieve the technical effect of ensuring the stability of the two half bodies 101 in the assembled state.

[0036] Furthermore, in this embodiment, the base 301 is also provided with a liquid discharge trough 303, and a discharge port 304 is provided on one side of the liquid discharge trough 303. When cleaning the two halves 101, the cleaning liquid that is rinsed falls into the liquid discharge trough 303 for collection, so as to avoid it flowing around and polluting the site.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
