Description

Technical Field

[0001] The present invention relates to the technical field of vegetable fermentation, in particular to a vegetable fermentation device and a vegetable fermentation method. Background Art

[0002] In the process of vegetable fermentation, fermentation tanks or ceramic cylinders are currently mostly used for fermentation. However, this type of fermentation container is mostly large in size and heavy in weight, and it takes a lot of manpower and material resources to transport, clean and load vegetables. The operation is very inconvenient and it is easy to cause damage to the container. At the same time, most traditional fermentation containers are opaque. During the fermentation process, people cannot intuitively observe the fermentation status of the vegetables, such as color changes, whether there is abnormal mold, etc., and can only check by opening the container, which increases the risk of contamination by miscellaneous bacteria and is not conducive to timely grasping the fermentation process and judging the fermentation end point.

[0003] Although some fermentation bags currently on the market have solved the portability problem of containers to a certain extent, in order to ensure the sealing inside the bag, most of them use heat sealing to seal the fermentation bag as a whole. During the fermentation process, it is sometimes necessary to regularly sample and test the fermentation degree, pH value, microbial indicators, etc. of the vegetables in order to understand the fermentation situation and make timely adjustments. However, if this type of fermentation bag is to be sampled, the seal needs to be destroyed, which will introduce the risk of contamination by miscellaneous bacteria, and the operation is inconvenient, which is not conducive to accurate monitoring of the fermentation process; for a few fermentation bags with an openable and closable function, the sealing effect is relatively poor, and the sealed environment inside the bag cannot be effectively guaranteed, which easily affects the normal fermentation of the vegetables in the bag.

[0023] Beneficial effects of the present invention:

[0024] The present invention provides a vegetable fermentation device and a vegetable fermentation method. By providing sealing strips, sealing grooves, fixing plates and connecting frames, when a staff member needs to ferment vegetables, the staff member can first add the raw materials into the interior of the bag body through the bag opening, and then press the two sets of sealing strips and sealing grooves near the bag opening so that the sealing strips are clamped in the sealing grooves, thereby achieving a one-time sealing of the interior of the bag body, ensuring that the vegetables in the bag body will not be contaminated by external bacteria during fermentation. At the same time, when people place the device, the connecting frame can play a supporting role, so that the bag opening position of the bag body is higher than the bag bottom position, so that the bag bottom bears the pressure of the vegetables, thereby avoiding the situation where the vegetables in the bag body are piled up at the bag opening for a long time, exerting pressure on the bag opening and causing its sealing ability to decrease.

[0025] When the locking plate is clamped with the fixing plate, the clamping shell will cooperate with the first connecting plate to clamp the top of the bag body, thereby achieving a triple seal inside the bag body.

[0026] The present invention provides a vegetable fermentation device and a vegetable fermentation method. Through the provided roller pressing assembly, the first bevel gear is driven to rotate when the first threaded screw rotates. At this time, the first bevel gear drives the second bevel gear meshed with it to rotate together. When the second bevel gear rotates, it can drive the second threaded screw to rotate. The second threaded screw is a bidirectional screw, so that the two groups of second threaded sleeves threadedly connected to the outer wall of the second threaded screw can drive the connecting column to move horizontally. During the horizontal movement of the connecting column, the clamping roller is pressed against the outer wall of the bag body by the action of the first spring, and the other side of the bag body is supported by the first connecting plate and the second connecting plate respectively. Therefore, during the horizontal movement of the clamping roller, an extrusion force can be applied to the sealing groove, thereby realizing the rolling treatment of the sealing groove and the sealing strip, further ensuring the stability of the clamping between the sealing groove and the sealing strip, and avoiding the occurrence of leakage.

[0027] The present invention provides a vegetable fermentation device and a vegetable fermentation method. Through the exhaust component, when a large amount of gas is generated by the vegetables in the bag during the fermentation process and reaches a certain pressure, the gas will exert an upward lifting force on the sealing gasket, thereby squeezing the sealing gasket open. At this time, the gas inside the bag will flow into the inside of the connecting pipe through the elbow and the hose. Since the connecting pipe and the fixed pipe are connected, as the gas in the connecting pipe continues to increase, the gas in the fixed pipe will also gradually increase, thereby squeezing the piston body in the fixed pipe to the outside. At this time, the piston body will be pressed tightly against the rubber block on one side of the first connecting plate, thereby achieving The bag end is now tightly sealed at a fixed point, and as the gas inside the bag continues to increase, the piston body and the rubber block will press the bag end tighter and tighter, meeting people's demand for sealing inside the bag. When the air pressure inside the bag increases to a certain intensity, the excess gas will be discharged through the vent pipe to avoid the bag bursting. In the process of the gas inside the bag being discharged from the exhaust pipe, the thin plate will rise and drive the movable rod to descend. At this time, the descending movable rod can drive the bent rod to press down the vegetables gathered at the bottom of the exhaust pipe, avoiding the exhaust pipe being blocked and affecting the normal exhaust of the entire exhaust assembly.

The side outer walls are respectively fixedly connected with a first connecting plate 9 and a second connecting plate 11. The first connecting plate 9 and the second connecting plate 11 are respectively located on one side of the two sets of sealing strips 32. When the first threaded screw 12 rotates, the first bevel gear 15 is driven to rotate. At this time, the first bevel gear 15 drives the second bevel gear 17 meshing with it to rotate together.

When a large amount of gas is generated in the fermentation process of the vegetables inside the bag body 1 and reaches a certain pressure, the gas will exert an upward lifting force on the sealing gasket 48, and the gas can squeeze the sealing gasket 48 open and be discharged from the inside of the bag body 1.

[0051] Preferably, a movable rod 51 is inserted into the interior of the circular cover shell 50, and one end of the movable rod 51 is fixedly connected to the top outer wall of the thin plate 45 with a second rotating seat 54, and the second rotating seat 54 is rotatably connected to the connecting rod 53, and the bottom outer wall of the ring plate 46 is fixedly connected to the vertical plate 55, and one side of the vertical plate 55 is rotatably connected to the connecting rod 53 through a rotating shaft. The bottom end of the movable rod 51 is fixedly connected to the curved rods 49 distributed in a circular shape at equal distances, and the cross-section of the curved rods 49 is wavy. In the process of the internal gas of the bag body 1 being discharged from the exhaust pipe 24, the thin plate 45 will rise. At this time, the seesaw structure formed by the connecting rod 53 can drive the movable rod 51 at one end of the connecting rod 53 to descend. At this time, the descending movable rod 51 can drive the curved rod 49 to press down the vegetables gathered at the bottom end of the exhaust pipe 24, so as to avoid the exhaust pipe 24 being blocked and affecting the normal exhaust of the entire exhaust assembly.

[0052] Preferably, the second sealing assembly includes an arc-shaped rod 4 fixedly connected to the outer wall of the first threaded sleeve 13 and the guide cylinder 7.

Since the connecting pipe 40 is connected to the fixed pipe 19, as the gas in the connecting pipe 40 continues to increase, the gas in the fixed pipe 19 will also gradually increase, thereby being able to squeeze the piston body 41 in the fixed pipe 19 to the outside.

When the air pressure inside the bag body 1 increases to a certain strength, the excess gas will be discharged through the vent pipe 38 to avoid the bag bursting.

[0053] A vegetable fermentation method, using a vegetable fermentation device according to the above embodiment, comprises the following steps:

[0054] Step 1: Choose fresh, pest-free vegetables, wash and dry them, remove surface moisture, and cut into appropriate-sized chunks, strips, or slices;

[0055] Step 2: Clean and disinfect the inside of the bag 1 by soaking or wiping it with an appropriate amount of disinfectant, then rinse it with clean water and let it dry;

[0056] Step 3: Open the bag 1 and put the pre-processed vegetables into the bag 1, with the filling amount being 70%-80% of the volume of the bag 1;

[0057] Step 4: Seal the bag 1 and place it in a suitable fermentation environment for fermentation. Set the corresponding fermentation time according to the type of vegetables and fermentation requirements. After fermentation is completed, take out the vegetables in the bag 1 for consumption or further processing.

[0058] In summary, with the help of the above technical solution of the present invention, when the staff needs to ferment the vegetables, they can first add the raw materials into the interior of the bag body 1 through the bag opening, and then press the two sets of sealing strips 32 and the sealing grooves 33 near the bag opening to make the sealing strips 32 snap into the inside of the sealing grooves 33, thereby achieving a one-time sealing of the interior of the bag body 1, ensuring that the vegetables in the bag body 1 will not be contaminated by external bacteria during fermentation. Then the staff rotates the rotating block 14, which can drive the first threaded screw 12 to rotate. During the rotation of the first threaded screw 12, the first threaded sleeve 13 threadedly connected to its outer wall can drive the locking plate 6 to move in the direction close to the fixed plate 2. As the first threaded screw 12 rotates, the first threaded sleeve 13 threadedly connected to its outer wall can drive the locking plate 6 to move in the direction close to the fixed plate 2. With the continuous rotation of the screw rod 12, the locking plate 6 will cooperate with the fixing plate 2 to clamp and fix the end of the bag body 1, and the multiple groups of protrusions 20 provided on one side of the locking plate 6 will cooperate with the pressing groove 52 opened on one side of the fixing plate 2, so that the bag body 1 can be intermittently pressed inside the pressing groove 52, effectively improving the clamping effect of the locking plate 6 on the bag body 1, and realizing a secondary seal inside the bag body 1. At the same time, the clamping shell 3 is fixedly connected to the first threaded sleeve 13 through the arc rod 4. At this time, the clamping shell 3 will move horizontally with the locking plate 6. When the locking plate 6 is clamped with the fixing plate 2, the clamping shell 3 will cooperate with the first connecting plate 9 to clamp and fix the top of the bag body 1, thereby realizing a tertiary seal inside the bag body 1.

[0059] When the first screw rod 12 rotates, the first bevel gear 15 is driven to rotate. At this time, the first bevel gear 15 drives the second bevel gear 17 meshing with it to rotate together. When the second bevel gear 17 rotates, it can drive the second screw rod 18 to rotate. The second screw rod 18 is a bidirectional screw rod, so that the two sets of second threaded sleeves 37 threadedly connected to the outer wall of the second screw rod 18 can drive the connecting post 21 to move horizontally. During the horizontal movement of the connecting post 21, the pressure roller 28 is pressed against the outer wall of the bag body 1 by the action of the first spring 26, and the other side of the bag body 1 is supported by the first connecting plate 9 and the second connecting plate 11 respectively. Therefore, during the horizontal movement of the pressure roller 28, an extrusion force can be applied to the sealing groove 33, thereby realizing the rolling processing of the sealing groove 33 and the sealing strip 32, further ensuring the stability of the clamping between the sealing groove 33 and the sealing strip 32, and avoiding the situation of leaking.

[0060] When the vegetables in the bag body 1 generate a large amount of gas during the fermentation process and reach a certain pressure, the gas will exert an upward lifting force on the sealing gasket 48, thereby squeezing the sealing gasket 48 open. At this time, the gas inside the bag body 1 will flow into the inside of the connecting pipe 40 through the curved pipe 43 and the hose 22. Since the connecting pipe 40 is connected to the fixed pipe 19, as the gas in the connecting pipe 40 continues to increase, the gas in the fixed pipe 19 will also gradually increase, thereby squeezing the piston body 41 in the fixed pipe 19 outward. At this time, the piston body 41 will be pressed tightly with the rubber block 10 on one side of the first connecting plate 9 to achieve a fixed-point compression seal on the end of the bag body 1. As the gas inside the bag body 1 continues to increase, the piston body 41 and the rubber block 10 will press the end of the bag body 1 tighter and tighter, meeting people's demand for sealing the interior of the bag body 1. When the air pressure inside the bag body 1 increases to a certain strength, the excess gas will be discharged through the vent pipe 38 to avoid the bag from bursting.

[0061] And in the process of the gas inside the bag body 1 being discharged from the exhaust pipe 24, the thin plate 45 will rise. At this time, the seesaw structure formed by the connecting rod 53 can drive the movable rod 51 at one end of the connecting rod 53 to descend. At this time, the descending movable rod 51 can drive the bent rod 49 to press down the vegetables gathered at the bottom of the exhaust pipe 24, so as to avoid the exhaust pipe 24 being blocked and affecting the normal exhaust of the entire exhaust assembly.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
