Description

Technical Field

[0001] This utility model relates to the field of brewing yeast culture fermentation technology, and specifically discloses a fermentation device for processing brewing yeast culture. Background Technology

[0002] Saccharomyces cerevisiae culture is a microecological preparation formed by the full fermentation of specific yeast strains using specific processes and culture media. This microecological product differs from products containing live yeast cells; its main active ingredient is the extracellular metabolites produced by Saccharomyces cerevisiae during fermentation. It also contains the denatured solid matrix after fermentation, the cell contents of the Saccharomyces cerevisiae after cell wall disruption, and the yeast cell wall itself.

[0003] Traditional brewing yeast fermenters generally use a single-layer agitator structure. The rotation trajectory of the single-layer agitator blades is uniform, making it difficult to break the axial stratification of the culture medium. This results in uneven material mixing and a single, unevenly distributed aeration system, which affects the quality of yeast fermentation. Therefore, a fermentation device for processing brewing yeast culture is needed to solve this problem. Utility Model Content

[0004] This invention proposes a fermentation device for processing brewing yeast culture. The device improves mixing efficiency through a double-layer counter-directional stirring structure. Oxygen is diverted and discharged, and then redistributed by a rotating dispersing rod, so that the oxygen can be evenly contacted with the culture medium in the tank, thereby improving the quality of yeast fermentation.

[0005] This utility model is implemented as follows: a fermentation device for processing brewing yeast culture includes a tank body with a discharge pipe connected to the bottom end, a valve installed on the outer wall of the discharge pipe, a flange cover detachably connected to the upper end face of the tank body by bolts, a feed pipe connected to the outer wall of the flange cover, a mixing mechanism provided inside the tank body, and a ventilation mechanism installed at the top of the tank body.

[0006] The mixing mechanism includes a first stirring rod disposed inside the tank and a rotating frame located outside the first stirring rod, a second stirring rod fixedly connected to the inner wall of the rotating frame and staggered with the first stirring rod, a bracket fixedly connected to the flange cover, a first bevel gear rotatably connected to one side of the bracket, a second bevel gear and a third bevel gear respectively meshing with the upper and lower sides of the first bevel gear, a motor disposed on the other side of the bracket and whose output end is fixedly connected to the first bevel gear, the middle part of the second bevel gear being fixedly connected to the first stirring rod, and a sleeve fixedly connected to the rotating frame being passed through and fixedly connected to the center of the third bevel gear, the sleeve being rotatably connected to the outer wall of the first stirring rod;

[0007] The mixing mechanism also includes multiple dispersing rods fixedly connected to the upper end face of the rotating frame;

[0008] The ventilation mechanism includes a ventilation cavity installed on the inner wall of the flange cover, multiple air outlets extending through the bottom of the ventilation cavity, and an air inlet pipe installed through the outer wall of the flange cover and communicating with the ventilation cavity.

[0009] As a preferred embodiment of the fermentation apparatus for processing brewing yeast culture according to this utility model, the outer wall of the tank is provided with a jacket, and the outer wall of the jacket is respectively connected to a water inlet and a water outlet.

[0010] In a preferred embodiment of the fermentation apparatus for processing brewing yeast culture according to this utility model, the bottom end of the rotating frame matches the bottom end of the tank.

[0011] As a preferred embodiment of the fermentation apparatus for processing brewing yeast culture according to this utility model, the outer wall of the rotating frame is fixedly connected with a scraper that contacts the inner wall of the tank.

[0012] As a preferred embodiment of the fermentation apparatus for processing brewing yeast culture according to this utility model, the outer wall of the ventilation chamber is provided with a notch for vertical feeding of the feed inlet.

[0013] As a preferred embodiment of the fermentation apparatus for processing brewing yeast culture according to this utility model, a support frame is fixedly connected to the outer wall of the tank, a controller is installed on the outer wall of the support frame, and the motor and valve are electrically connected to the controller.

[0014] As a preferred embodiment of the fermentation apparatus for processing brewing yeast culture according to this utility model, the upper end face of the flange cover is fixedly connected to a support for supporting the motor.

[0015] The beneficial effects of this utility model are:

[0016] 1. The motor drives the first bevel gear to rotate, which causes the second and third bevel gears to rotate synchronously in opposite directions. This, in turn, drives the first stirring rod and the rotating frame to rotate synchronously in opposite directions. The synchronous counter-rotation of the first and second stirring rods ensures uniform mixing of the culture medium inside the tank. The double-layer counter-rotating structure improves mixing efficiency.

[0017] 2. Oxygen is introduced into the ventilation chamber and discharged through multiple vents. As the rotating frame rotates, it drives the dispersing rod to rotate, which further disperses the oxygen, ensuring that the oxygen comes into uniform contact with the culture medium in the tank, thereby improving the quality of yeast fermentation.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] Please see Figure 1-3 A fermentation apparatus for processing brewing yeast culture includes a tank 1 with a discharge pipe 102 connected to its bottom end, a valve installed on the outer wall of the discharge pipe 102, a flange cover 101 detachably connected to the upper end face of the tank 1 by bolts, a feed pipe connected to the outer wall of the flange cover 101, a mixing mechanism provided inside the tank 1, and a ventilation mechanism installed at the top of the tank 1.

[0025] The mixing mechanism includes a first stirring rod 205 disposed inside the tank 1 and a rotating frame 207 located outside the first stirring rod 205, a second stirring rod 208 fixedly connected to the inner wall of the rotating frame 207 and staggered with the first stirring rod 205, a bracket 2 fixedly connected to the flange cover 101, a first bevel gear 202 rotatably connected to one side of the bracket 2, a second bevel gear 203 and a third bevel gear 204 respectively meshing with the upper and lower sides of the first bevel gear 202, a motor 201 disposed on the other side of the bracket 2 and whose output end is fixedly connected to the first bevel gear 202, the middle part of the second bevel gear 203 fixedly connected to the first stirring rod 205, and a sleeve 206 fixedly connected to the rotating frame 207 through the center of the third bevel gear 204, the sleeve 206 rotatably connected to the outer wall of the first stirring rod 205;

[0026] The mixing mechanism also includes a plurality of dispersing rods 209 fixedly connected to the upper end face of the rotating frame 207;

[0027] The ventilation mechanism includes a ventilation cavity 4 installed on the inner wall of the flange cover 101, multiple air outlets 402 that pass through the bottom of the ventilation cavity 4, and an air inlet pipe 401 that passes through the outer wall of the flange cover 101 and communicates with the ventilation cavity 4.

[0028] In this embodiment: the culture medium is put into the tank 1 through the feed port, and the motor 201 is started at the same time, so that the motor 201 drives the first bevel gear 202 to rotate, causing the second bevel gear 203 and the third bevel gear 204 to rotate synchronously in opposite directions, which in turn drives the first stirring rod 205 and the rotating frame 207 to rotate synchronously in opposite directions. Through the synchronous opposite rotation of the first stirring rod 205 and the second stirring rod 208, the culture medium in the tank 1 is uniformly mixed, thereby improving the mixing efficiency through the double-layer opposite stirring structure.

[0029] While mixing, the air inlet pipe 401 is connected to the oxygen supply equipment, and oxygen is introduced into the ventilation chamber 4. The oxygen can be diverted and discharged through multiple air outlets 402. As the rotating frame 207 rotates, the dispersing rod 209 can be rotated. The rotating dispersing rod 209 can further disperse the oxygen, so that the oxygen can come into uniform contact with the culture medium in the tank 1 (the control of internal air pressure, temperature, acid and alkali, etc. are all existing technologies and will not be described in detail here), thereby improving the quality of yeast fermentation.

[0030] As a technical optimization of this utility model, the outer wall of the tank 1 is provided with a jacket 3, and the outer wall of the jacket 3 is respectively connected to the water inlet and the water outlet.

[0031] In this embodiment: Cooling water is injected into the jacket 3 through the inlet, and the tank 1 is cooled by the cooling water. The heated cooling water can be discharged through the outlet and connected to an external refrigeration device to cool the heated water, thereby achieving the effect of rapid cooling of the tank 1.

[0032] As a technical optimization of this utility model, the bottom end of the rotating frame 207 matches the bottom end of the tank 1.

[0033] In this embodiment: by matching the shape of the bottom end of the rotating frame 207 with the bottom end of the tank 1, it is convenient to stir and mix the material at the bottom end of the tank 1.

[0034] As a technical optimization of this utility model, a scraper that contacts the inner wall of the tank 1 is fixedly connected to the outer wall of the rotating frame 207.

[0035] In this embodiment, the material adhering to the inner wall of the rotating frame 207 can be scraped off by a scraper, so that the material is mixed evenly.

[0036] As a technical optimization of this utility model, the outer wall of the ventilation cavity 4 is provided with a notch for vertical feeding of material into the inlet.

[0037] In this embodiment, the notch ensures that the material falling from the feed inlet can smoothly enter the tank 1.

[0038] As a technical optimization of this utility model, a support frame is fixedly connected to the outer wall of the tank 1, and a controller is installed on the outer wall of the support frame. The motor 201 and the valve are both electrically connected to the controller.

[0039] In this embodiment, the controller can control the motor 201 and the valve to work normally.

[0040] As a technical optimization of this utility model, the upper end face of the flange cover 101 is fixedly connected with a support for supporting the motor 201.

[0041] In this embodiment: the motor 201 can be supported by the support, so that the motor 201 can be placed stably.

[0042] The working principle and usage process of this utility model are as follows: The culture medium is put into the tank 1 through the feed port, and the motor 201 is started at the same time. The motor 201 drives the first bevel gear 202 to rotate, which causes the second bevel gear 203 and the third bevel gear 204 to rotate synchronously in opposite directions. This drives the first stirring rod 205 and the rotating frame 207 to rotate synchronously in opposite directions. Through the synchronous opposite rotation of the first stirring rod 205 and the second stirring rod 208, the culture medium in the tank 1 is evenly mixed. The material adhering to the inner wall of the rotating frame 207 can be scraped off by the scraper. Thus, the mixing efficiency can be improved through the double-layer opposite stirring structure.

[0043] While mixing, the air inlet pipe 401 is connected to the oxygen supply equipment to introduce oxygen into the ventilation chamber 4. The oxygen can be diverted and discharged through multiple air outlets 402. As the rotating frame 207 rotates, the dispersing rod 209 can be rotated. The oxygen can be dispersed again by the rotating dispersing rod 209, so that the oxygen can be evenly contacted with the culture medium in the tank 1 (the control of internal air pressure, temperature, acid and alkali, etc. are all existing technologies and will not be described in detail here).

[0044] Cooling water is injected into the jacket 3 through the inlet, and the cooling water cools the tank 1, thereby achieving the effect of rapid cooling of the tank 1.
