Description

Technical Field

[0001] The invention relates to the technical field of leek flower fermentation devices, and in particular to a fermentation device for preparing leek flowers and a fermentation process thereof. Background Art

[0002] Cauliflower is rich in dietary fiber, vitamins, minerals, and sulfides, and has a high water content; these characteristics make it very suitable for fermentation, and thus for preparing a unique sauce. Fermentation equipment is usually used to ferment leek flowers into leek sauce, but existing fermentation equipment still has the following defects during use: For example, Chinese patent publication number CN117814469A discloses a method for making chive flower sauce and a fermentation container. In this method, the raw materials are washed and then placed in a 4°C environment for storage for 3 to 8 hours. The fermentation container comprises a housing, a universal joint, and a stirring mechanism. The housing is a container with a cavity inside, which is used to hold the chive flower sauce and maintain an oxygen-tight state. The top center of the housing is connected to a universal joint, and the stirring mechanism extends through the universal joint into the housing to stir and mix the chive flower sauce in the housing while maintaining an oxygen-tight state. The present invention improves the method for making chive flower sauce and the fermentation container, increases the concentration of flavor substances in the chive flower sauce, and makes the chive flower sauce uniform, well-fermented, and less susceptible to deterioration.

[0003] During the fermentation process of chive flower sauce, although the stirring mechanism installed in the fermentation container can improve the mixing effect, it cannot effectively control the temperature changes inside the chive flower sauce. Especially in industrial production, the fermentation container is large, and the temperature difference between the center and the inner wall of the container is significant, and the temperature difference can even exceed 5°C. This uneven temperature situation will lead to uneven acidity in the chive flower sauce. Especially for chive flowers with a high water content, if the temperature is uneven during the fermentation process, the microbial activity, metabolite distribution and chemical reaction rate in different areas will vary, which will cause significant differentiation in the fermentation effect and seriously affect the final fermentation quality.

[0014] A fermentation process for preparing leek flowers, using the above-mentioned fermentation device for preparing leek flowers, specifically comprises the following steps: S1201, Mixing and Temperature Control: The motor drives the stirring rod to rotate, which in turn drives the spiral blades on the stirring rod to rotate synchronously.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1-11 , a fermentation device based on the preparation of leek flowers, such as Figure 1-Figure 3 As shown, it includes a tank body 2 arranged in a shell body 1; a mixing temperature control mechanism 3 and a flow temperature control mechanism 4 are provided on the shell body 1, and the mixing temperature control mechanism 3 and the flow temperature control mechanism 4 are both used to control the fermentation temperature of the leek flowers in the tank body 2; the mixing temperature control mechanism 3 includes a stirring rod 31, a spiral blade 32 and a motor 33; wherein the stirring rod 31 is coaxially arranged in the tank body 2; the stirring rod 31 is an inverted conical structure; since the bottom material will be subjected to the pressure of the top material, the inverted conical structure of the stirring rod 31 is adopted in the design. When the spiral blade 32 starts to rotate, it can effectively disperse more materials on the top upward and to the surroundings, thereby significantly reducing the pressure on the bottom material, and thus being more conducive to the overall uniform dispersion of the material upward and to the surroundings; the spiral blade 32 is provided on the stirring rod 31, and the spiral blade 32 is adapted to the conical structure of the stirring rod 31; the motor 33 is installed on the shell body 1, and is used to drive the stirring rod 31 to rotate around its axis.

[0021] It should be noted that when the motor 33 drives the stirring rod 31 to rotate, the spiral blade 32 generates an axial thrust, which lifts the material at the bottom center of the tank body 2 upward along the spiral trajectory and diffuses it to the surrounding areas; the circular setting of the bottom of the tank body 2 allows the material to fall back to the bottom center under the action of gravity, and then the spiral blade 32 drives the material to rise and disperse, thus forming a circulating flow; in this process, the material with higher temperature near the center of the tank body 2 continues to diffuse to the surrounding areas, and the material with lower temperature near the inner wall of the tank body 2 continues to move to the center, which can reduce the temperature difference between the material near the center position and the inner wall position of the tank body 2, and improve the fermentation consistency; it can be understood that the material with higher temperature is relative to the material with lower temperature; and in the early stage of fermentation, the spiral blade 32 is used to drive the material to circulate, so that the leek flowers are in full contact with the microorganisms, promote the uniform distribution of metabolites, and improve the fermentation consistency.

[0022] See also Figure 1-Figure 3 The flow temperature control mechanism 4 includes a first temperature control mechanism 41 and a second temperature control mechanism 42 ; the first temperature control mechanism 41 is used to control the temperature of the inner wall of the tank body 2 ; the second temperature control mechanism 42 is used to control the temperature at the center of the tank body 2 .

[0023] It should be noted that the first temperature control mechanism 41 circulates the temperature control medium through the first temperature control cavity 413 between the shell 1 and the tank body 2, directly acting on the inner wall of the tank body 2 to adjust the peripheral temperature; it can be understood that the temperature control medium is existing technology, such as cooling water or hot water; the second temperature control mechanism 42 transports the temperature control medium through the second temperature control cavity 422 inside the stirring rod 31, penetrating into the central area of ​​the tank body 2, and specifically controlling the central temperature; thereby eliminating the defect of the traditional device with a significant temperature difference between the center and the inner wall, accurately matching the temperature requirements of each stage of fermentation, optimizing microbial activity, and improving the efficiency of flavor substance generation.

[0024] See also Figure 1-Figure 3 The first temperature control mechanism 41 includes a first delivery port 411, a second delivery port 412 and a first water pump; it can be understood that the first water pump is a prior art, which is not shown in the figure and will not be described in detail; the first delivery port 411 and the second delivery port 412 are both arranged in the shell 1, and a first temperature control cavity 413 is provided between the shell 1 and the tank body 2, and the first delivery port 411 and the second delivery port 412 are both connected to the first temperature control cavity 413, and the first water pump is installed in the shell 1, and the output end of the first water pump is connected to the first temperature control cavity 413 through the first delivery port 411; the first water pump is a bidirectional water pump; when the first water pump is driven in the forward direction, it is used to introduce the temperature control medium into the first temperature control cavity 413; when the first water pump is driven in the reverse direction, it is used to export the temperature control medium out of the first temperature control cavity 413.

[0025] It should be noted that when the first water pump is driven in the forward direction, the temperature control medium flows from the first delivery port 411 into the first temperature control cavity 413, conducts heat through the side wall of the tank body 2, and reduces or increases the temperature of the inner wall; the second temperature control mechanism 42 is connected to the first temperature control cavity 413. At this time, when the temperature control medium is introduced into the center of the tank body 2, the first water pump is driven in the reverse direction, so that a suction force is generated on the temperature control medium in the center of the tank body 2, thereby causing the temperature control medium to enter the first temperature control cavity 413 and be discharged from the first delivery port 411; The bidirectional water pump design supports bidirectional circulation of the temperature control medium, avoiding the local temperature lag caused by traditional unidirectional flow and improving the temperature control response speed; and the medium flow direction can be dynamically adjusted according to the real-time fermentation temperature data to ensure that the temperature of the inner wall of the tank 2 is uniform and stable.

[0026] See also Figure 1-Figure 5 The second temperature control mechanism 42 includes a second water pump 421, which is installed in the shell 1. A second temperature control chamber 422 is provided in the stirring rod 31. The output end of the second water pump 421 is connected to the second temperature control chamber 422 through a delivery pipe, and the bottom of the second temperature control chamber 422 is connected to the first temperature control chamber 413; the second temperature control mechanism 42 also includes a rotating block 423 and a connecting sleeve 425; the rotating block 423 is fixed to the stirring rod 31, and a first through hole 424 communicating with the second temperature control chamber 422 is provided on the rotating block 423; the connecting sleeve 425 is fixed to the shell 1, and the connecting sleeve 425 is sleeved on the rotating block 423; the end of the delivery pipe on the second water pump 421 is fixed to the connecting sleeve 425; when the motor 33 drives the rotating block 423 to rotate, the delivery pipe maintains communication with the first through hole 424 through the connecting sleeve 425.

[0027] It should be noted that the second water pump 421 pumps the temperature control medium into the second temperature control chamber 422 through the delivery pipe, and transfers the temperature to the stirring rod 31 and the spiral blade 32, thereby achieving the purpose of controlling the temperature at the center of the tank body 2; the temperature control medium is always in a flowing state. As the second water pump 421 works, the temperature control medium flows into the first temperature control chamber 413 through the second through hole 427, mixes and circulates with the peripheral medium, and forms a central and peripheral heat conduction closed loop.

[0028] See also Figure 3-Figure 6 The second temperature control mechanism 42 also includes a rotating seat 426; the rotating seat 426 is arranged at the bottom of the tank body 2, and the stirring rod 31 is rotatably connected to the rotating seat 426. The stirring rod 31 is provided with a plurality of third through holes 428 connected to the second temperature control cavity 422, and the rotating seat 426 is provided with a plurality of second through holes 427 connected to the first temperature control cavity 413. The second temperature control cavity 422 is connected to the first temperature control cavity 413 through the second through holes 427 and the third through holes 428.

[0029] It should be noted that when the second water pump 421 pumps the temperature control medium into the second temperature control chamber 422 through the delivery pipe, as the stirring rod 31 rotates, the second through hole 427 and the third through hole 428 are controlled to be continuously aligned or misaligned, thereby automatically controlling the flow rate of the temperature control medium to ensure the temperature control effect; by building a temperature control channel into the stirring rod 31, stirring and temperature control can be achieved, and the dual-cavity connected design reduces the use of temperature control medium, improves energy utilization, and reduces the energy consumption cost of industrial production.

[0030] See also Figure 7-11 The tank body 2 is provided with an isolation mechanism 5, which includes a mounting ring 51, a rotating rod 52, a first baffle 53, a second baffle 54, a blocking block 55 and a linkage mechanism 57; the mounting ring 51 is slidably connected to the tank body 2 along the axis of the tank body 2, the rotating rod 52 is sleeved on the stirring rod 31, and the rotating rod 52 is rotatably connected to the mounting ring 51 around the axis of the stirring rod 31, and a pair of first baffles 53 are fixed on the mounting ring 51, and a pair of second baffles 54 are fixed on the rotating rod 52, the first baffle 53 and the second baffle 54 are staggered, and the first baffle 53 and the second baffle The plates 54 are in contact with each other through sealing strips; a linkage mechanism 57 is provided between the stirring rod 31 and the mounting ring 51, and is used to drive the mounting ring 51 to rotate, so as to drive the first baffle 53 to rotate; a plurality of fourth through holes are provided on the first baffle 53 and the second baffle 54, and a blocking block 55 is provided in the fourth through hole, and a cross groove 56 is provided on the blocking block 55; when the mounting ring 51 is driven to move downward and squeeze the space in the tank body 2, the cross groove 56 will be squeezed, so that the cross groove 56 is forced to open; when the blocking block 55 loses its restriction, the cross groove 56 is reset to seal against each other.

[0031] It should be noted that when the leek flowers are introduced into the tank body 2, the first baffle 53 and the second baffle 54 are completely overlapped, so that the mounting ring 51 is in an open state, which does not affect the introduction of the leek flowers; when the motor 33 drives the stirring rod 31 to rotate forward to control the material temperature, the rotation of the stirring rod 31 will first drive the second baffle 54 on the rotating rod 52 to rotate until the rotating rod 52 conflicts with the mounting ring 51. At this time, the rotating rod 52, the first baffle 53 and the second baffle 54 are used to seal the top of the tank body 2. As the stirring rod 31 continues to rotate, the rotating rod 52 is restricted by the mounting ring 51, which will drive the mounting ring 51 to move downward. At this time, the first baffle 53 and the second baffle 54 on the mounting ring 51 will squeeze the top The material is squeezed out of the tank body 2, so that the excess water on the top of the tank body 2 squeezes the blocking block 55, causing the cross slot 56 to be forced to open and allow water to pass through; and after completing the stirring and temperature control, the stirring rod 31 is slightly controlled to rotate in the opposite direction. At this time, the mounting ring 51 is driven upward by the linkage mechanism 57, thereby making the first baffle 53 and the second baffle 54 slightly away from the material on the top of the tank body 2, so that the blocking block 55 loses its restriction. At this time, the cross slot 56 is restored to close, and the excess water will be isolated on the first baffle 53 and the second baffle 54. At this time, when entering the deep fermentation stage, the shell 1 is sealed, and the first baffle 53, the second baffle 54 and the blocking block 55 cooperate to form a good secondary sealing effect, thereby ensuring the fermentation effect of the material. Example 2: Please refer to Figure 7-10 The linkage mechanism 57 includes a threaded rod 571, a pair of springs 572 and a retaining ring 573; the threaded rod 571 is arranged between the output end of the motor 33 and the stirring rod 31, the mounting ring 51 is threadedly connected to the threaded rod 571, and a pair of springs 572 are respectively arranged at both ends of the threaded rod 571, one end of the spring 572 is fixed to the threaded rod 571, and the retaining ring 573 is fixed to the other end of the spring 572, and the retaining ring 573 is arranged close to the mounting ring 51.

[0032] When the motor 33 drives the stirring rod 31 to rotate forward, the threaded rod 571 first drives the rotating rod 52 to rotate until the rotating rod 52 conflicts with the mounting ring 51. As the stirring rod 31 continues to rotate, the rotating rod 52 is restricted by the mounting ring 51. At this time, the mounting ring 51 is driven to move downward until the threaded portion of the threaded rod 571 is close to separation from the rotating rod 52. At this time, the retaining ring 573 is acted upon by the spring 572 to provide a reverse thrust to the rotating rod 52, so that when the motor 33 drives the stirring rod 31 to continue to rotate forward, the rotating rod 52 always maintains the engagement with the threaded portion of the threaded rod 571. Therefore, when the motor 33 drives the stirring rod 31 to rotate in the reverse direction, the rotating rod 52 can be restored to the threaded connection with the threaded portion of the threaded rod 571, thereby driving the rotating rod 52 to move back, thereby driving the mounting ring 51 to move upward while driving the second baffle 54 to rotate, so that the mounting ring 51 is opened to facilitate the replenishment of materials.

[0033] See also Figures 1-12 A fermentation process for preparing leek flowers, using the above-mentioned fermentation device for preparing leek flowers, specifically comprises the following steps: S1201, Mixing and Temperature Control: The motor 33 drives the stirring rod 31 to rotate, driving the spiral blade 32 on the stirring rod 31 to rotate synchronously. As a result, the material located at the bottom center of the tank body 2 is acted upon by the spiral blade 32 and begins to be lifted upward from the bottom center along the spiral trajectory of the blade. During the lifting process, the material gradually spreads to the surrounding areas. After being dispersed to the surrounding areas, the material gradually returns to the bottom center of the tank body 2 under the action of gravity, and is then driven by the spiral blade 32 to circulate the material. S1202, flow temperature control: by setting passages at the center and outer wall of the tank body 2, a temperature control medium is introduced therein, and the heat conduction performance of the temperature control medium is used to control the temperature at the center and inner wall of the tank body 2 to be consistent.
