Description

Technical Field

[0001] The present application relates to the field of fermentation technology, and in particular to a fermentation machine suitable for fruit and vegetable enzymes. Background Art

[0002] At present, with the popularization of the concept of healthy diet, fermented fruit and vegetable enzymes are favored by consumers for their rich nutrients and bioactive substances. The traditional fermentation process mostly adopts static or natural stirring methods, which usually rely on the metabolic activities of microorganisms to achieve the mixing of substances. However, this method has disadvantages such as low mixing efficiency, slow mass transfer, and long fermentation cycle. In order to improve fermentation efficiency and product quality, mechanical stirring fermentation machines came into being.

[0003] Mechanically stirred fermenters use built-in agitators (such as paddle, turbine or anchor agitators) to achieve forced mixing of the fermentation medium. The rotation of the agitator can generate shear force, promote mixing between air, nutrients and microorganisms, and thus accelerate the fermentation process.

[0004] However, the air of the existing mechanical stirring fermentation machine is injected from the top of the machine body, and the mechanical stirring process cannot ensure that the fermentation liquid and the air at the bottom of the fermentation machine are evenly mixed. Summary of the invention

[0005] In order to overcome the above problems, the present application provides a fermentation machine suitable for fruit and vegetable enzymes.

[0006] The present application provides a fermentation machine suitable for fruit and vegetable enzymes, comprising a fermentation tank, wherein the fermentation tank contains fermentation liquid, and further comprising: a stirring shaft, which is vertically arranged in the fermentation tank, and the top end is penetrated and extended to the top end of the fermentation tank, and the top end of the fermentation tank is provided with a driving member for driving the stirring shaft to rotate; a stirring disk, which is arranged inside the fermentation tank, and a plurality of stirring disks are horizontally formed on the stirring shaft, and the plurality of stirring disks are vertically evenly distributed, the stirring disk and the stirring shaft are hollow inside, and an air pipe connected to the stirring shaft is arranged on the top of the fermentation tank, and air is transported to the stirring disk through the stirring shaft; a plurality of air holes are evenly penetrated on the disk surface of each stirring disk, connecting the interior of the fermentation tank with the interior of the stirring disk, and transporting the gas in the stirring disk to the fermentation tank.

[0007] Preferably, it further comprises: paddles, a plurality of which are evenly formed on the side wall of the stirring disk, the plurality of paddles are vertically arranged, and the paddles and the air holes are distributed alternately.

[0008] Preferably, it also includes: edge blades, which are vertically arranged and correspond to each blade one by one, connected to the blades and the inner wall of the fermentation tank, and rotate synchronously with the blades, and a gap is set between the edge blades to allow the fermentation liquid to flow; a ring rail, formed on the inner wall of the fermentation tank, and a slider adapted to the ring rail is set on the edge blade to allow the edge blade to slide along the ring rail.

[0009] Preferably, it also includes: an inflation strip, which is vertically arranged and fixed to the side wall of the fermentation tank and the bottom wall of the fermentation tank, and the inflation strip is provided with a plurality of air holes, which are evenly spaced along the length direction of the inflation strip to inject air into the fermentation tank.

[0010] Preferably, it also includes: a blocking rod, which is vertically arranged inside the stirring shaft, fixedly connected to the top of the fermentation tank and does not rotate with the stirring shaft, and the bottom end of the blocking rod extends to the bottom end of the stirring shaft; a blocking plate, which is formed in multiple pieces at the portion of the blocking rod corresponding to each stirring disk, and the multiple blocking plates are bent, and the curvature of the bending is adapted to the curvature of the side wall of the stirring disk. The blocking plates correspond to the air holes one by one and fit the inner wall of the stirring disk, so as to block the air holes to prevent the fermentation tank from communicating with the inside of the stirring disk.

[0014] In summary, the present invention has at least the following beneficial effects:

[0015] 1. The present invention provides a hollow stirring shaft and a stirring disk, and cooperates with air holes to evenly release air from the surface of the stirring disk into the fermentation liquid, thereby achieving uniform stirring of the fermentation liquid and improving the fermentation efficiency.

[0016] 2. The present invention preferably adopts a design in which blades and pores are alternately distributed. The rotating stirring of the blades further promotes the uniform mixing of the fermentation liquid. At the same time, the setting of the edge blades and the ring rails enhances the stirring effect and prevents the fermentation liquid from forming a dead corner at the edge of the fermentation tank.

[0017] 3. The present invention adopts a blocking plate to block the air holes.

[0022] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0023] The present application embodiment discloses a fermentation machine suitable for fruit and vegetable enzymes. Figure 1 and Figure 2 A fermentation machine suitable for fruit and vegetable enzymes includes a fermentation tank 1, which contains fermentation liquid. A stirring shaft 12 is vertically arranged on the top wall of the fermentation tank 1, and the bottom end of the stirring shaft 12 passes through the top of the fermentation tank 1 and extends to the top of the bottom wall of the fermentation tank 1. A motor is arranged on the top of the fermentation tank 1 corresponding to the stirring shaft 12, and a reduction gear set is correspondingly arranged to drive the stirring shaft 12 to rotate.

[0024] Reference Figure 2 and Figure 3 The part of the stirring shaft 12 located inside the fermentation tank 1 is formed with a plurality of horizontally arranged stirring disks 14, the stirring disk 14 is hollow inside, so that the inside of the stirring disk 14 is shell-shaped, and a plurality of air holes 142 are pierced on the side wall of the stirring disk 14, and the plurality of air holes 142 are circumferentially distributed at equal angles, connecting the inside of the fermentation tank 1, the inside of the stirring disk 14, and the inside of the stirring shaft 12. An air pipe 11 connecting the inside of the stirring shaft 12 is arranged at the top of the fermentation tank 1. The air pipe 11 is plugged into the top of the stirring shaft 12 from the top of the fermentation tank 1, connected to the internal space of the stirring shaft 12, and air is supplied to the inside of the fermentation tank 1 through the stirring shaft 12. The plug-in connection relationship makes the air pipe 11 rotate without following the rotation of the stirring shaft 12.

[0025] Reference Figure 2 and Figure 3The air pipe 11 does not need to extend into the fermentation tank 1, and only plays the role of air supply. A plurality of blades 15 are evenly distributed on the side wall of the stirring plate 14, and the blades 15 are vertically arranged and distributed alternately with the air holes 142. With the rotation of the motor, the blades 15 rotate to stir the fermentation liquid, and at the same time, the air holes 142 inject air into the fermentation liquid to provide oxygen required for fermentation.

[0026] Reference Figure 2 and Figure 3 A vertically arranged blocking rod 13 is formed on the inner bottom wall of the fermentation tank 1 corresponding to the air pipe 11. The diameter of the blocking rod 13 is smaller than the diameter of the stirring shaft 12. The top end of the blocking rod 13 is inserted from the bottom end of the stirring shaft 12 and extends to the stirring disk 14 at the top of the stirring shaft 12. The portion of the blocking rod 13 corresponding to the stirring disk 14 horizontally extends a plurality of metal rods toward the side wall of the stirring disk 14. The end of the metal rod away from the blocking rod 13 is formed with a blocking plate 141. The blocking plate 141 is bent, and its bent plate surface is parallel to the bent side wall of the stirring disk 14. The blocking plate 141 fits the air hole 142 to block the air hole 142.

[0027] In this embodiment, the part where the stirring shaft 12 and the blocking rod 13 are inserted uses the existing technology of bearing sealing to prevent the fermentation liquid from entering the inner cavity of the stirring shaft 12. At the same time, due to the fixation of the blocking rod 13, the blocking rod 13 does not rotate with the rotation of the stirring shaft 12. Therefore, the bearing seal can also reduce the sealing effect of the blocking rod 13 and the stirring shaft 12.

[0028] Reference Figure 2 and Figure 3 A connecting rod is horizontally extended at the top and bottom of the side of the blade 15 away from the stirring disk 14. A plurality of edge blades 16 are slidably arranged on the inner wall of the fermentation tank 1. The edge blades 16 are vertically arranged. The edge blades 16 correspond to the number of blades 15 one by one. The side of the edge blade 16 facing the blade 15 is connected to the blade 15 through the above-mentioned connecting rod, so that the edge blade 16 rotates synchronously with the blade 15; a plurality of ring rails 17 are formed on the top and bottom ends of the inner wall of the fermentation tank 1 corresponding to the edge blade 16, and are arranged corresponding to stirring disks 14 of different heights. Slide blocks adapted to the ring rails 17 are fixedly connected to the top and bottom ends of the edge blades 16. When the edge blades 16 slide, the slide blocks slide, which plays a guiding role in stabilizing the sliding of the ring rails 17.

[0029] Reference Figure 2 and Figure 3 A plurality of inflatable strips 18 are fixedly connected to the bottom of the fermentation tank 1. The interior of the inflatable strips 18 is hollowed out, and a plurality of air holes 142 are penetrated through the top side wall of the inflatable strips 18. The plurality of air holes 142 are penetrated at equal intervals along the length direction of the inflatable strips 18. One end of the inflatable strips 18 is fixedly connected to the inner wall of the fermentation tank 1. An air pipe 11 is disposed outside the fermentation tank 1 corresponding to the inflatable strips 18 to transport air to the inflatable strips 18 to ensure the oxygen supply to the bottom of the fermentation tank 1.

[0030] In this embodiment, a pH sensor 19 is fixedly connected to the inner wall of the fermentation tank 1, and its bottom end extends downward, until the detection end of the sensor extends into the fermentation liquid to detect the pH value; a temperature sensor is fixedly connected to the inner wall of the fermentation tank 1 to measure the temperature of the fermentation liquid.

[0031] In this embodiment, a control component 2 is provided at the top of the fermentation tank 1 to receive the measurement data of the pH sensor and the temperature sensor, and provide a button for human-computer interaction. Relevant personnel can change the operating parameters of the fermentation tank 1 according to the measurement data of the two sensors.

[0032] The implementation principle of a fermentation machine suitable for fruit and vegetable enzymes in an embodiment of the present application is as follows: when the stirring shaft 12 rotates, the blades 15 on the stirring plate 14 and the edge blades 16 on the inner wall of the fermentation tank 1 rotate with the blades 15 to stir the fermentation liquid, and at the same time, the air holes 142 inject air into the fermentation tank 1 to provide gas uniformity inside the fermentation liquid.

[0033] When the stirring shaft 12 stops rotating, the air hole 142 is in contact with the blocking plate 141 to prevent the fermentation liquid from flowing into the stirring disk 14 .

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
