Description

Field of the invention

[0001] The present invention relates to a device for improving fermentation products and, in particular, to an innovative device in which, by using an enzyme additive and the stirring and mixing process carried out by the mixing and stirring device, the structure of the nutrient medium is changed and a highly efficient fermentation culture substrate is produced, thus increasing the amount of fermentation products in subsequent fermentation processes. State of the art

[0002] Fermentation is a process that allows microorganisms to multiply in large quantities and produce the desired fermentation products (e.g., yeast cultivation). Typically, a culture medium containing various nutrients and bacteria is used in industry to serve as a substrate for the growth of microorganisms. Additionally, chemicals are added to ferment the culture medium and promote the growth of microorganisms, thus producing fermentation products. Although this process is widely used in the food industry, there are still some problems that need to be solved in practical application.

[0003] As is well known, during fermentation, chemicals such as acids and alkalis are initially added to the nutrient medium to promote the growth of microorganisms and thus produce fermentation products. The addition of acidic chemicals often leads to carbonization of the nutrient medium after prolonged fermentation, which can slow the growth of microorganisms or even cause their death, leading to a reduction in the yield of fermentation products and a reduction in the efficiency of the nutrient medium. If alkaline chemicals are added instead, this can also lead to carbonization of the nutrient medium after prolonged fermentation. In addition, the residual salts of the alkaline chemicals inhibit the growth of microorganisms, resulting in bottlenecks in the production of fermentation products and reducing productivity.For cost reasons, companies can also use non-commercially available culture media in large quantities to produce fermentation products. This demonstrates that there is still considerable room for breakthroughs and improvements in the conventional production process for fermentation products.

[0004] Therefore, in view of the above-mentioned problems in the prior art, the growth of microorganisms can be improved and a large amount of fermentation products can be produced if a better growth environment is provided during the cultivation of microorganisms. Object of the invention

[0005] The main object of the present invention is to provide a device for improving fermentation products. The technical problem to be solved is to address and solve the problems existing in the conventional technology.

[0006] The technical features of the present invention that can solve the problems are described below. The device for improving fermentation products comprises: a fermentation culture substrate formed by mixing bacteria, water, and nutrient medium; an enzyme additive added to the fermentation culture substrate; a mixing and stirring device in the form of a hollow container having a container space, the container space accommodating the fermentation culture substrate, a stirring component disposed in the container space, one end of the stirring component connected to a drive motor, and the stirring component driven by the drive motor to stir and mix the fermentation culture substrate in the container space.

[0007] Compared with conventional techniques, the innovative and unique design of the present invention enhances the efficiency of the chemical reaction by adding the enzyme additive to the fermentation culture substrate. The physical changes generated after stirring and mixing alter the structure and composition of the nutrient medium in the fermentation culture substrate to facilitate bacterial survival and growth, thus providing a highly efficient fermentation culture substrate. This allows the number and growth rate of bacteria to be increased in subsequent fermentations, thus providing industrial applicability for significantly increasing the yield of enzyme products and shortening the fermentation time. Brief description of the drawings Fig.Figure 1 shows a schematic representation of the composition of the fermentation culture substrate according to the present invention; Fig. 2 shows a view of the entire structure of the device for improving fermentation products according to the invention; Fig. Figure 3 shows a schematic process block diagram according to the present invention. Detailed description of the embodiment

[0008] It is based on the Fig.1 to 3, which show a preferred embodiment of the device for improving fermentation products according to the invention. The following description only explains one embodiment of the invention and is not intended to limit the claims. The device for improving fermentation products comprises the following: a fermentation culture substrate 10 formed by mixing bacteria 11, water 12, and nutrient medium 13, wherein the bacteria 11 can be Gram-positive bacteria, and the nutrient medium 13 consists of a group of nutrients and raw materials required for the growth and proliferation of the bacteria 11; an enzyme additive 20 added to the fermentation culture substrate 10, wherein the enzyme additive 20 is preferably, but not limited to, cellulase, peptidase, or amylolytic enzyme; a mixing and stirring device 30 which has the shape of a hollow container with a container space 31, wherein the container space 31 accommodates the fermentation culture substrate 10, a stirring component 32 is arranged in the container space 31, one end of the stirring component 32 is connected to a drive motor 33, and the stirring component 32 is driven by the drive motor 33 to stir and mix the fermentation culture substrate 10 located in the container space 31 (as indicated by the arrow L1 in Fig.2). It should be noted that the enzyme additive 20, after being added to the fermentation culture substrate 10, can initiate a chemical reaction to promote the activity of the nutrient medium 13 and further prevent the occurrence of carbonization in the nutrient medium 13. Since the enzyme additive 20 is not in a heat-resistant form, the enzyme additive 20 may be inactivated during use by the user, but without hindering the growth of the bacteria 11, by processing at high temperature, under high pressure, and by means of moist heat treatment during the fermentation process.

[0009] In the implementation of the present invention, an introduction opening 34 and a discharge opening 35 continuously connected thereto may be provided at predetermined positions of the mixing and stirring device 30, through which the fermentation culture substrate 10 can be introduced and discharged.

[0010] Furthermore, the stirring component 32 of the mixing and stirring device 30 is in the shape of a stirring rod, and the surface of the stirring component 32 is provided with a double-helical stirring screw 36. Therefore, when the stirring component 32 rotates, a shear-like stirring and mixing effect can be generated, so that the fermentation culture substrate 10 is mixed more evenly.

[0011] In this way, in the present invention, the fermentation culture substrate 10 can trigger a chemical reaction after the addition of the enzyme additive 20 to promote the activity of the nutrient medium 13. Together with the physical changes resulting from the stirring and mixing process, the structure and composition of the nutrient medium 13 contained in the fermentation culture substrate 10 can be altered to facilitate the survival and growth of bacteria, thus providing a highly efficient fermentation culture substrate 10. This can increase the yield of enzyme products in subsequent fermentations by 15 to 20% and shorten the fermentation time.

[0012] The following table shows the comparison of the fermentation time and the amount of fermentation product between the fermentation culture substrate 10 according to the invention and a conventional nutrient medium: Fermentation culture substrate 10 : conventional nutrient medium Fermentation time (hours) Fermentation product amount (%) 0: 2 24 100 1 : 1 23 117 2:0 21,7 125

[0013] As can be seen from the table above, when using a conventional nutrient medium, an amount of approximately 100% of the fermentation product is obtained after 24 hours of fermentation. When the fermentation culture substrate 10 according to the invention is mixed halfway with conventional nutrient medium, an amount of 117% of the fermentation product can be produced after 23 hours of fermentation. When the fermentation culture substrate 10 according to the invention is used entirely for the fermentation, the fermentation time can be shortened to 21.7 hours, and an amount of 125% of the fermentation product can be produced.

[0014] The following describes the manufacturing process of the present invention according to the above-described structural composition design: It is based on the Fig.1 to 3. Since active enzymes such as cellulase and peptidase are used as media for the enzyme supplement 20 in the present invention, a chemical reaction of these active enzymes with the nutrients and raw materials contained in the nutrient medium 13 of the fermentation culture substrate 10 can be initiated to increase the activity of the nutrient medium 13 and the growth and survival rate of bacteria 11. Fig.2. After the enzyme additive 20 is added to the fermentation culture substrate 10, it is introduced into the container space 31 via the introduction port 34 of the mixing and stirring device 30 and rotated, stirred, and mixed by the stirring component 32 of the mixing and stirring device 30. Since the surface of the stirring component 32 is provided with a double-helical stirring screw 36, a shear-like stirring and mixing effect can be generated upon rotation. After the stirring and mixing process, the nutrient medium 13 of the fermentation culture substrate 10 may undergo physical changes (namely, a change in the molecular structure inside), thereby changing the structure of the nutrient medium 13. When the user uses the fermentation culture substrate 10 as a basis for fermentation, the number and growth rate of the bacteria 11 can be increased, thereby shortening the fermentation time.If the number and growth rate of bacteria 11 are increased in this way, the yield of enzyme products also increases accordingly.

[0015] The present invention provides an apparatus for improving fermentation products, comprising: a fermentation culture substrate formed by mixing bacteria, water, and nutrient medium; an enzyme additive added to the fermentation culture substrate; a mixing and stirring device having the form of a hollow container having a container space, the container space accommodating the fermentation culture substrate, a stirring component disposed in the container space, one end of the stirring component being connected to a drive motor, and the stirring component being driven by the drive motor to stir and mix the fermentation culture substrate disposed in the container space.The present invention is based on the fact that the addition of the enzyme additive to the fermentation culture substrate promotes the efficiency of the chemical reaction, and the physical changes generated after the stirring and mixing process alter the structure and composition of the nutrient medium in the fermentation culture substrate to facilitate the survival and growth of bacteria, thus providing a highly efficient fermentation culture substrate. In this way, the number and growth rate of bacteria can be increased in subsequent fermentation processes, thereby providing industrial applicability for significantly increasing the yield of enzyme products and shortening the fermentation time.
