Technical Field

[0001] This utility model relates to the field of sunflower meal fermentation technology, specifically to a sunflower meal fermentation device for increasing the soluble protein content. Background Technology

[0002] Fermentation equipment refers to the equipment and systems used in the biological fermentation process, mainly for the cultivation and biotransformation of microorganisms. Sunflower meal is a by-product after sunflower seed oil extraction. Due to its high protein content, it can be used as feed in animal husbandry. Fermentation equipment is required in the use of sunflower meal, and stirring structures are needed in the use of sunflower meal fermentation equipment to improve the utilization effect of soluble protein content.

[0003] However, most existing technical solutions have the following drawbacks:

[0009] Also includes:

[0010] The discharge pipe is fixedly connected to the middle of the lower end of the fermentation tank, and the lactic acid bacteria feed pipe is fixedly installed on the right side of the upper end of the fermentation tank. The upper side of the lactic acid bacteria feed pipe is movably installed with a disassembly structure. The middle of the upper end of the fermentation tank is fixedly installed with a first motor, and the lower side of the first motor is fixedly installed with a first stirring rod. The fermentation tank has a jacket inside, and the upper rear end of the fermentation tank is fixedly connected with a water inlet pipe, and the lower rear end of the fermentation tank is fixedly connected with a water outlet pipe.

[0011] A connecting pipe is fixedly installed on the upper left side of the fermentation tank, and a mixing chamber is fixedly connected to the upper end of the connecting pipe. A raw material feed pipe is fixedly installed on the upper left side of the mixing chamber, and a microbial feed pipe is fixedly installed on the upper right side of the mixing chamber. A second motor is fixedly installed on the upper middle side of the mixing chamber, and a stirring structure is fixedly installed at the lower end of the second motor.

[0012] Preferably, the stirring structure includes a second stirring rod, which is fixedly installed at the lower end of the second motor. A connecting wheel is movably connected to the upper left side of the second stirring rod, and a mounting plate is movably connected to the outer side of the connecting wheel.

[0018] Preferably, the support block and the second stirring rod are connected by a sliding manner, and the vertical cross-section of the support block is an "L" shaped structure.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the sunflower meal fermentation device for increasing soluble protein content can easily increase the soluble protein content in sunflower meal, facilitate stirring of sunflower meal, and facilitate the addition of lactic acid bacteria;

[0020] 1. By pouring sunflower meal raw material into the mixing chamber through the raw material feed pipe, and then introducing Bacillus subtilis and yeast into the mixing chamber through the inoculum feed pipe, the second motor is started, causing the second motor to drive the second stirring rod to rotate in the middle of the mixing chamber. This causes the connecting wheel, which meshes with the second stirring rod, to rotate in the upper part of the mixing chamber through the bearing. This, in turn, causes the mounting plate, which meshes with the connecting wheel, to drive the support block to rotate on the outside of the second stirring rod. The mounting plate then drives the mounting plate to rotate, so that both the mounting plate and the second stirring rod drive the stirring blades to mix the sunflower meal raw material, Bacillus subtilis, and yeast, facilitating the mixing of sunflower meal.

[0021] 2. After stirring, the sunflower meal enters the fermentation tank through the connecting pipe for two days of aerobic fermentation. Under aerobic conditions, Bacillus subtilis and yeast will grow rapidly, producing a large amount of protease. The protease can degrade the large molecular proteins in the sunflower meal into small molecular proteins and amino acids. Then, lactic acid bacteria are poured into the fermentation tank through the lactic acid bacteria feed pipe. The cover plate is installed on the upper side of the lactic acid bacteria feed pipe to form a sealed space in the fermentation tank, so that the sunflower meal can undergo two days of anaerobic fermentation inside the fermentation tank. Under anaerobic conditions, lactic acid bacteria can grow rapidly, decomposing and utilizing small molecular peptides and amino acids while producing lactic acid to provide flavor. The first motor is started, which drives the first stirring rod to stir the sunflower meal inside the fermentation tank. After fermentation, the sunflower meal falls into the inside of the drum dryer through the discharge pipe for drying until the moisture content is below 12% to form the finished feed product, which facilitates the improvement of the soluble protein content in the sunflower meal.

[0022] 3. By rotating the fixing rod, the fixing rod is threaded to the lower outer side of the cover plate, thereby allowing the fixing rod to slide outward at the lower end of the cover plate. This separates the fixing rod from the outside of the lactic acid bacteria inlet pipe. Then, pull the cover plate upward to separate it from the upper side of the lactic acid bacteria inlet pipe, making it convenient to add lactic acid bacteria. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-6This utility model provides a technical solution: a sunflower meal fermentation device for improving soluble protein content, comprising: a support plate 2 fixedly installed on the outer side of the lower end of a fermentation tank 1, and a drum dryer 4 fixedly installed on the inner side of the support plate 2; a discharge pipe 3 fixedly connected to the middle side of the lower end of the fermentation tank 1; a lactic acid bacteria feed pipe 14 fixedly installed on the right side of the upper end of the fermentation tank 1, with a detachable structure movably installed on the upper side of the lactic acid bacteria feed pipe 14; a first motor 5 fixedly installed on the middle side of the upper end of the fermentation tank 1, and a first stirring rod 6 fixedly installed on the lower side of the first motor 5; a jacket 22 opened inside the fermentation tank 1; a water inlet pipe 23 fixedly connected to the upper rear end of the fermentation tank 1; and a water outlet pipe 21 fixedly connected to the lower rear end of the fermentation tank 1. Hot water is poured into the jacket 22 through the water inlet pipe 23 to control the water temperature inside the jacket 22 at 37 degrees Celsius. The cooled water is discharged through the water outlet pipe 21. The stirred sunflower meal enters the fermentation tank 1 through a connecting pipe 7 for aerobic fermentation. Under aerobic conditions, Bacillus subtilis and yeast will grow rapidly over two days, producing a large amount of protease. The protease can degrade the large molecular proteins in sunflower meal into small molecular proteins and amino acids. Then, the lactic acid bacteria are poured into the fermentation tank 1 through the lactic acid bacteria feed pipe 14. The disassembly structure is installed on the upper side of the lactic acid bacteria feed pipe 14, so that the fermentation tank 1 forms a sealed space, allowing the sunflower meal to undergo anaerobic fermentation inside the fermentation tank 1 for two days. Under anaerobic conditions, lactic acid bacteria can grow rapidly, decomposing and utilizing small molecular peptides and amino acids while producing lactic acid to provide flavor. The first motor 5 is started, which drives the first stirring rod 6 to stir the sunflower meal inside the fermentation tank 1. The fermented sunflower meal falls into the drum dryer 4 through the discharge pipe 3 and is dried until the moisture content is less than 12% to form the finished feed product, which facilitates the increase of soluble protein content in the sunflower meal. The disassembly structure is rotated to separate the disassembly structure on the upper side of the lactic acid bacteria feed pipe 14, which facilitates the addition of lactic acid bacteria.

[0032] The connecting pipe 7 is fixedly installed on the upper left side of the fermentation tank 1, and the upper end of the connecting pipe 7 is fixedly connected to the mixing chamber 8. The upper left side of the mixing chamber 8 is fixedly installed with the raw material feed pipe 9, and the upper right side of the mixing chamber 8 is fixedly installed with the inoculum feed pipe 10. The upper middle side of the mixing chamber 8 is fixedly installed with the second motor 17, and the lower end of the second motor 17 is fixedly installed with the stirring structure. Sunflower meal raw material is poured into the interior of the mixing chamber 8 through the raw material feed pipe 9, and then Bacillus subtilis and yeast are introduced into the interior of the mixing chamber 8 through the inoculum feed pipe 10. The stirring structure is started to mix the sunflower meal raw material, Bacillus subtilis and yeast, which facilitates the mixing of sunflower meal.

[0033] When using this sunflower meal fermentation device to increase soluble protein content, specifically as follows: Figure 1 , Figure 3 and Figure 6In the process, sunflower meal raw material is poured into the mixing chamber 8 through the raw material feed pipe 9. Then, Bacillus subtilis and yeast are introduced into the mixing chamber 8 through the inoculum feed pipe 10. The second stirring rod 11 is connected to the connecting wheel 18 by meshing, and the connecting wheel 18 is connected to the mixing chamber 8 through a bearing. The second motor 17 is started, causing the second stirring rod 11 to rotate inside the mixing chamber 8. The connecting wheel 18 is connected to the mounting plate 19 by meshing, thereby connecting the connecting wheel 11 to the second stirring rod 11. The wheel 18 rotates on the upper side inside the mixing chamber 8 via a bearing. The support block 20 is slidably connected to the second stirring rod 11, and the vertical cross-section of the support block 20 is an "L" shape. This causes the mounting plate 19, which meshes with the connecting wheel 18, to rotate the support block 20 on the outside of the second stirring rod 11. The mounting plate 19 then rotates the mounting plate 12, causing both the mounting plate 12 and the second stirring rod 11 to drive the stirring blades 13 to mix the sunflower meal raw material, Bacillus subtilis, and yeast, thus facilitating the mixing of the sunflower meal.

[0034] Specific examples Figure 1 , Figure 4 and Figure 5 In the process, hot water is poured into the jacket 22 through the inlet pipe 23 to maintain the water temperature inside the jacket 22 at 37 degrees Celsius. The cooled water is discharged through the outlet pipe 21. The stirred sunflower meal enters the fermentation tank 1 through the connecting pipe 7 for aerobic fermentation for two days. Under aerobic conditions, Bacillus subtilis and yeast will grow rapidly and produce a large amount of protease. The protease can degrade the large molecular proteins in the sunflower meal into small molecular proteins and amino acids. Then, lactic acid bacteria are poured into the fermentation tank 1 through the lactic acid bacteria inlet pipe 14. The cover plate 15 is installed on the lactic acid bacteria inlet. The upper side of pipe 14 forms a sealed space in fermentation tank 1, allowing sunflower meal to undergo anaerobic fermentation inside fermentation tank 1 for two days. Under anaerobic conditions, lactic acid bacteria can grow rapidly, decomposing and utilizing small molecule peptides and amino acids while producing lactic acid to provide flavor. The first motor 5 is started, causing the first stirring rod 6 to stir the sunflower meal inside fermentation tank 1. After fermentation, the sunflower meal falls through discharge pipe 3 into the inside of drum dryer 4 for drying until the moisture content is below 12% to form a finished feed product, which facilitates increasing the soluble protein content in sunflower meal.

[0035] Specific examples Figure 1 and Figure 2In the process of rotating the fixing rod 16, the cover plate 15 and the fixing rod 16 are connected by threads, and the fixing rod 16 is symmetrically distributed about the center line of the cover plate 15. The fixing rod 16 is threaded on the lower outer side of the cover plate 15, so that the fixing rod 16 slides outward at the lower end of the cover plate 15, thereby separating the fixing rod 16 from the outside of the lactic acid bacteria inlet pipe 14. The cover plate 15 and the lactic acid bacteria inlet pipe 14 are connected by a snap-fit ​​method, and the lower outer side of the cover plate 15 is provided with a protrusion structure. Pulling the cover plate 15 upward further separates the cover plate 15 from the upper side of the lactic acid bacteria inlet pipe 14, which facilitates the addition of lactic acid bacteria.
