Description

Technical Field

[0001] This utility model relates to the field of fermentation technology, and in particular to a turning device for cultivating Aspergillus in soy sauce. Background Technology

[0002] Aspergillus soysauce plays a crucial role in the brewing process of soy sauce. It is one of the core microorganisms in soy sauce brewing, closely related to Aspergillus oryzae, but possesses unique advantages in enzyme secretion and flavor formation.

[0003] Aspergillus oryzae is usually mixed with Aspergillus oryzae or Aspergillus niger in a certain proportion to participate in the fermentation of soy sauce. The content and quality of Aspergillus oryzae play a decisive role in the flavor of soy sauce. During the koji-making process, the koji needs to be turned and cooled frequently to ensure that the Aspergillus is kept at 30°C. The Aspergillus grows best at this temperature, and the brewed soy sauce has the best flavor.

[0004] In existing technologies, in addition to manual turning of the koji, mechanical equipment is also used to turn the fermentation platform of Aspergillus at regular intervals. This method can replace the tedious manual turning process to a certain extent and save people the trouble of constantly monitoring the temperature of Aspergillus. However, the direct turning method is difficult to turn the inside of Aspergillus, which may result in the center temperature of Aspergillus remaining high, thus affecting the quality of fermentation. Utility Model Content

[0005] In order to solve the above problems, this utility model provides a turning device for Aspergillus oryzae cultivation in soy sauce.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a fermentation box for soy sauce Aspergillus cultivation, including a fermentation box for placing Aspergillus, a support mechanism and a drive mechanism for supporting the fermentation box are provided below the fermentation box, the drive mechanism includes a motor and a transmission shaft connected to the output shaft of the motor, a bushing for engaging with the transmission shaft is provided inside the fermentation box, and a stirring component for turning the Aspergillus is provided on the bushing.

[0007] By adopting the above-mentioned scheme, the driving mechanism drives the fermentation chamber itself and the stirring components inside the fermentation chamber to move. On the one hand, the vibration of the fermentation chamber can break up the structure of the Aspergillus floc, making the internal structure of the Aspergillus floc loose, which facilitates heat dissipation and can prevent the internal temperature from becoming too high, ensuring that the fermentation work is carried out at a suitable temperature. At the same time, the stirring components will rotate under the drive of the motor, thereby turning the Aspergillus at the bottom to the surface, thus realizing the exchange of the inside and outside of the Aspergillus, which is conducive to the overall fermentation of the Aspergillus. It can also accelerate the heat dissipation rate, so that the Aspergillus that was originally inside the Aspergillus floc can reduce the temperature to a reasonable range more quickly.

[0008] Furthermore, the fermentation chamber is provided with an openable cover at the top, and both the cover and the bottom of the fermentation chamber are provided with heat dissipation holes.

[0009] By adopting the above solution, the heat dissipation holes can also enable the bottom of the Aspergillus cluster to have a certain heat dissipation capacity, thereby preventing overheating inside the Aspergillus cluster.

[0010] Furthermore: multiple fermentation boxes are provided, and the multiple fermentation boxes are stacked one on top of the other.

[0011] By adopting the above scheme, the number of fermentation platforms can be adjusted according to demand to meet different production requirements at different times. When there are more fermentation platforms, multiple koji-making processes can be completed simultaneously. When there are fewer fermentation platforms, it is easier to grasp the fermentation state inside the Aspergillus mass and make adjustments, thereby enabling Aspergillus to have higher quality fermentation.

[0012] Furthermore, the output shaft of the motor is also provided with a drive bevel gear, the support mechanism includes a support frame and a mounting frame, the mounting frame is provided with a rotating shaft, the rotating shaft is provided with an eccentric wheel and a transmission bevel gear fixedly connected to each other, and the support frame is slidably connected with a push rod that simultaneously abuts against the eccentric wheel and the fermentation box. When the eccentric wheel rotates, the push rod intermittently lifts the fermentation box, and the top of the push rod collides with the fermentation box to cause vibration.

[0013] By adopting the above solution: when the eccentric wheel rotates, it will cause the push rod to slide up and down. At this time, since the push rod is also in contact with the fermentation box, it will lift and lower the fermentation box. The cycle will cause the fermentation box to vibrate, which will disperse the Aspergillus clumps. Dispersing the Aspergillus clumps will also help the subsequent stirring components to turn over the Aspergillus at the bottom.

[0014] Furthermore, a limiting ring is provided on the top rod, the limiting ring being located on the upper and lower sides of the support frame and abutting against the support frame as the top rod moves.

[0015] By adopting the above solution, the limiting ring can limit the vertical movement distance of the top rod, thereby preventing the top rod from lifting the fermentation box too high and causing excessive vibration of the fermentation box. This ensures that the fermentation box can vibrate at a more appropriate amplitude and frequency, breaking up the Aspergillus clumps without causing Aspergillus to splatter everywhere.

[0016] Furthermore: the agitator includes a mounting plate and comb plates disposed on the upper and lower sides of the mounting plate. One end of the mounting plate is fixedly connected to the bushing, and each comb plate has an inclined surface on both sides.

[0017] By adopting the above scheme, the sloping surface makes it easier to scoop up the Aspergillus at the bottom, and also allows the Aspergillus at the bottom to come to the surface along the sloping surface, thereby achieving the effect of exchanging the positions of Aspergillus in different positions in the Aspergillus mass, and can more rationally and thoroughly mix the Aspergillus in each position.

[0018] Furthermore: a groove is provided inside the bushing, and a locking block is provided on the top of the drive shaft for engaging with the groove.

[0019] By adopting the above solution, the engagement between the slot and the block allows the bushing and the drive shaft to rotate synchronously, thereby driving the comb plate to rotate synchronously as well, thus achieving the effect of scraping up Aspergillus.

[0020] Furthermore: the fermentation box, the drive mechanism and the support mechanism are provided with an outer shell, the outer sides of the support frame and the mounting frame are fixed to the outer shell, the motor is placed at the bottom of the outer shell, and the side of the fermentation box is fixedly connected to the inner surface of the outer shell.

[0021] By adopting the above solution, the outer shell creates a certain degree of airtightness in the fermentation environment, thereby creating conditions conducive to fermentation and making the support structure more stable.

[0022] In summary, this utility model has the following beneficial effects:

[0023] The eccentric wheel drives the push rod upward, causing intermittent vibration in the fermentation chamber. This loosens the structure of the Aspergillus floc, facilitating the dissipation of internal heat during fermentation and maintaining the Aspergillus floc at a suitable temperature, thus improving fermentation quality. Meanwhile, the stirring component moves the Aspergillus at the bottom to the surface, achieving an exchange effect between the inside and outside of the Aspergillus floc. This further dissipates the heat from the internal Aspergillus floc, preventing fermentation quality problems caused by overheating and resulting in higher quality Aspergillus.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] like Figure 1 and Figure 2 As shown, a turning device for Aspergillus cultivation in soy sauce includes a fermentation box 1 for holding Aspergillus. The Aspergillus ferments in the fermentation box 1. The top of the fermentation box 1 is provided with an openable cover 13. Both the cover 13 and the bottom of the fermentation box 1 are provided with heat dissipation holes 14. The cover 13 can provide a certain degree of airtightness to the fermentation box 1, which facilitates the fermentation process. At the same time, it can also block the Aspergillus to a certain extent, preventing the Aspergillus from splashing during the subsequent turning process. The heat dissipation holes 14 can provide a small amount of air circulation to the fermentation box 1, which can meet the conditions required for fermentation while also dissipating a certain amount of heat. Multiple fermentation boxes 1 are provided and stacked one on top of the other. The number of fermentation boxes 1 can be adjusted according to actual needs. When there are more boxes, more Aspergillus can be fermented at the same time, thereby increasing the yield. When there are fewer boxes, more precise control can be made to the fermentation boxes 1, thereby improving the quality of Aspergillus.

[0032] like Figure 2 As shown, a support mechanism 2 and a drive mechanism 3 are provided below the fermentation box 1 to support the fermentation box 1. The fermentation box 1, the drive mechanism 3 and the support mechanism 2 are covered by a shell 4. The motor 31 is placed at the bottom of the shell 4. The shell 4 can provide a certain protection for the fermentation box 1, so that the fermentation process can proceed smoothly. At the same time, it can create a sealed space in a larger area to further ensure the smooth progress of fermentation.

[0033] like Figure 2 and Figure 3As shown, the drive mechanism 3 includes a motor 31 and a transmission shaft 32 connected to the output shaft of the motor 31. The stirring component 12 can turn the Aspergillus at the bottom of the Aspergillus mass to the surface, thereby allowing the Aspergillus with a higher internal temperature to cool down more quickly and thus recover to a suitable temperature more quickly. The fermentation chamber 1 is provided with a bushing 11 for engaging with the transmission shaft 32. The bushing 11 is provided with a stirring component 12 for turning the Aspergillus. The stirring component 12 includes a mounting plate 121 and a drive shaft 32 for mounting the drive shaft 32. The upper and lower comb plates 122 on the plate 121 are fixedly connected at one end to the bushing 11. Each comb plate 122 has a slope 123 on both sides. The slope 123 can lift the Aspergillus at the bottom and then the Aspergillus comes to the surface along the slope 123. The bushing 11 has a slot 111. The top of the drive shaft 32 has a locking block 321 for cooperating with the slot 111. The cooperation between the slot 111 and the locking block 321 allows the stirring member 12 and the drive shaft 32 to rotate synchronously.

[0034] like Figure 2 and Figure 3 As shown, the output shaft of the motor 31 is also equipped with a drive bevel gear 33. The support mechanism 2 includes a support frame 21 and a mounting frame 22. The outer sides of both the support frame 21 and the mounting frame 22 are fixed to the outer shell 4. After being fixed to the outer shell 4, the support frame 21 and the mounting frame 22 have a higher connection strength, which can further ensure the stability of the mounting frame 22 and the support frame 21. The mounting frame 22 is equipped with a rotating shaft 23, and the rotating shaft 23 is equipped with an eccentric wheel 24 and a transmission bevel gear 25 that are fixedly connected to each other. The support frame 21 is slidably connected with a push rod 26 that simultaneously abuts against the eccentric wheel 24 and the fermentation box 1. When the eccentric wheel 24 rotates, the push rod 26 intermittently impacts the fermentation box 1. Because the side of the fermentation box 1 is in contact with the outer shell 4, the support mechanism 21 is equipped with a drive bevel gear 33. The support mechanism 2 includes a support frame 21 and a mounting frame 2 ... The inner surface of the shell 4 is fixedly connected, so the top rod 26 impacts the fermentation box 1 from the top, causing the fermentation box 1 to vibrate. This loosens the Aspergillus cluster structure, which is not only conducive to heat dissipation, but also makes it easier for the comb plate 122 to break up the Aspergillus cluster. The top rod 26 is provided with a limiting ring 27, which is located on the upper and lower sides of the support frame 21 and abuts against the support frame 21 as the top rod 26 moves. The limiting ring 27 can limit the vertical movement distance of the top rod 26, preventing the fermentation box 1 from vibrating too much due to excessive impact force. This, to a certain extent, prevents Aspergillus from splashing during vibration and also protects the structural strength of the fermentation box 1 itself, preventing the bottom of the fermentation box 1 from being damaged by the top rod 26.

[0035] The scope of protection of this utility model includes, but is not limited to, the above embodiments. The scope of protection of this utility model is defined by the claims. Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art shall fall within the scope of protection of this utility model.
