Description

Technical Field

[0001] The present invention relates to the technical field of fermentation devices, and specifically to a fermentation device for radish pickles. Background Art

[0002] Radish is a plant that can be used both as medicine and food. Its Tibetan name is "Nyima". According to the famous Tibetan medical classic "Four Medical Tantras", radish has the effects of being sweet in taste and warm in nature, clearing heat and detoxifying, and nourishing and increasing oxygen. Radish is sweet in taste and warm in nature, can relieve summer heat, nourish and increase oxygen, improve eyesight and promote diuresis, stimulate appetite and aid digestion, relieve hangover, and help with weight loss. It has a very high regulatory and supplementary effect on symptoms such as anti-hypoxia, anti-fatigue, reducing blood lipid, and relieving discomfort due to acclimatization. It is widely planted in biological agriculture and related industries. Fresh radish can stimulate appetite and aid digestion, and also has the effect of clearing heat and detoxifying. Currently, radish is pickled and fermented to make pickles.

[0003] The preparation process of pickles uses fresh vegetables as raw materials. After being pickled with salt to make pickle blanks, the made pickle blanks are then subjected to methods such as being pressed with heavy objects or soaked in water to reduce the salt content. Then, sauces are added for sealed fermentation, and the sugars, amino acids, and flavor substances in the sauces are absorbed to obtain the finished pickles.

[0004] Common fermentation devices are usually single tanks. Especially for the fermentation process of radish, the temperature and humidity need to be controlled. Therefore, conventional stacked fermentation tanks are not conducive to the fermentation of radish. Moreover, during the process of making pickles, the salt content needs to be reduced. In this process, the existing technology relies on manual extrusion to drain the excess brine. The excess brine can be reused. However, for stacked fermentation tanks, there are problems of uneven heating of the radish inside and insufficient contact with the salt, which will affect the quality of pickles made from radish. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a fermentation device for radish pickles to solve the problems raised in the above background art. The structure of the present invention is novel. The radishes are evenly placed on the placement plate in layers, which is conducive to uniform heating. By squeezing the placement plate, it is convenient to drain the excess salt. Through the cooperation of the driving component and the spraying component, it is convenient to sprinkle the recycled brine back on the radishes or to rinse the radishes to reduce the salt content. It is more convenient for the preparation of radishes, and there is no need to transfer and desalt during the process, improving the fermentation and preparation efficiency.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A fermentation device for turnip pickles includes a fermentation tank. The top of the fermentation tank is provided with a top plate, and a reflux layer is arranged at the bottom of the fermentation tank. Liquid storage tanks are fixed on both sides of the fermentation tank. A placement component is arranged inside the fermentation tank, and the placement component includes a placement plate. Four groups of placement plates are slidably installed at equal intervals inside the fermentation tank, and a pressing plate is arranged at the upper end of the topmost placement plate in the fermentation tank.

Four leakage grooves are equidistantly arranged on the surface of the hollow tube, and a spraying component is arranged at the bottom of the hollow tube at the leakage grooves. The spraying component includes a rotating ring. The rotating ring is rotationally and sealingly installed on the surface of the hollow tube at the bottom of the leakage groove through a bearing, and a vertical tube is inserted into the hollow tube. Spherical nozzles are equidistantly arranged on the surface of the rotating ring, and the spherical nozzles are connected to the vertical tube. The top of the vertical tube is connected to the liquid storage tank. A driving component is arranged at the upper end of the top plate. The driving component includes a second gear. The top of the vertical tube penetrates through the top plate through a bearing in a rotational manner, and the second gear is sleeved on the outer wall of the vertical tube that penetrates out.

[0007] Further, a drain pipe is arranged on one side of the reflux layer, and both ends of the reflux layer are communicated with the liquid storage tank through a water pump and a pipeline. Two conveying pipes are fixed on the top of the liquid storage tank. The top of the vertical tube is rotationally installed with a connecting pipe through a bearing, and a connecting flange is installed between the connecting pipe and the conveying pipe.

[0008] Further, the driving component further includes a toothed ring. The toothed ring is rotationally installed between the four second gears on the top of the top plate through a bearing, and the toothed ring is meshed and connected with the second gear. A motor is fixed on the outside of the top plate through a mounting frame, and a first gear is fixed on the output end of the motor. The first gear is meshed and connected with the toothed ring.

[0009] Further, heat insulation layers are arranged on the inner walls around the fermentation tank, and a temperature control board is installed inside the heat insulation layers. A temperature sensor and a humidity sensor are arranged inside the fermentation tank.

[0010] Further, a pull rod is fixed at the center of the top of the top plate. The lower end of the pull rod is fixedly connected to the bottommost placement plate, and a pull ring is arranged at the upper end of the pull rod.

[0011] Further, pressing rods are slidably inserted on both sides of the pull rod at the upper end of the top plate, and the bottom of the pressing rods is fixedly connected to the pressing plate.

[0012] Further, second springs are fixed at the four sides between adjacent placement plates and the pressing plate. Bellows are fixed on the periphery of the second springs, and both ends of the bellows are fixedly connected to the corresponding placement plate or pressing plate.

[0013] Further, the spraying assembly further includes a horizontal pipe. A horizontal pipe is fixed at the position of the spherical nozzle corresponding to the vertical pipe. The other end of the horizontal pipe is slidably and sealingly inserted with a telescopic pipe, and the other end of the telescopic pipe is fixedly connected to the rear end of the spherical nozzle.

[0014] Further, a first spring is sleeved on the outer surface of the telescopic pipe, and both ends of the first spring are fixedly connected to the rear end of the spherical nozzle and the horizontal pipe respectively.

[0015] Further, a spray opening is formed at the front end of the spherical nozzle. A plug is fixed inside the horizontal pipe, and the plug penetrates into the spherical nozzle. The size of the plug is the same as that of the spray opening.

[0016] The beneficial effects of the present invention: A fermentation device for radish pickles of the present invention includes a fermentation tank; a top plate; a pressing rod; a pull rod; a heat preservation layer; a temperature control board; a reflux layer; a drain pipe; a driving assembly; a motor; a first gear; a gear ring; a second gear; a liquid storage tank; a delivery pipe; a connecting flange; a connecting pipe; a vertical pipe; a placing assembly; a pressing plate; a placing plate; a hollow pipe; a leakage trough; a spraying assembly; a rotating ring; a spherical nozzle; a horizontal pipe; a spray opening; a plug; a first spring; a telescopic pipe; a corrugated pipe; a second spring;

[0017] 1. Under normal conditions of the present invention, the placing plate shields the leakage trough part. At this time, the spherical nozzle extends out of the rotating ring, the spray opening is open, and the liquid in the horizontal pipe is sent out through the telescopic pipe and the spherical nozzle. Cooperating with the driving assembly to drive the rotation of the vertical pipe, it is thus evenly sprayed on the surface of the radish from the four corners of the placing plate, making the flushing or brine soaking of the radish more sufficient.

[0018] 2.

The corrugated pipe outside the second spring can prevent the radish from getting stuck inside the second spring when the second spring expands and contracts, affecting the flexibility.

[0020] 4. In the present invention, the heat is transferred to the inside of the fermentation tank through the heat preservation layer. Cooperating with the radish placed in layers, it makes the adjustment of the fermentation temperature of the radish more convenient and the radish is heated more evenly.

[0021] 5. The present invention drives the first gear to rotate through a motor and engages with the toothed ring. The toothed ring engages with four groups of second gears, driving the four groups of vertical pipes to rotate, and spraying brine or clean water to make the distribution uniform.

[0022] 6. Compared with the prior art, the present invention evenly places the yacon roots on the placement plate in a layered manner, which is beneficial to uniform heating. By squeezing the placement plate, it is convenient to discharge the excess salt. Through the cooperation of the driving assembly and the spraying assembly, it is convenient to re-spray the recovered brine on the yacon roots or to rinse the yacon roots to reduce the salt content, which is more convenient for the preparation of yacon roots. During the process, there is no need to transfer and desalt, improving the fermentation and preparation efficiency. Brief Description of the Drawings

[0031] To make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0032] Please refer to Figures 1 to 7 , the present invention provides a technical solution: a fermentation device for radish pickles, including a fermentation tank 1, a top plate 11 is provided at the top of the fermentation tank 1, and a reflux layer 2 is arranged at the bottom of the fermentation tank 1. Liquid storage tanks 4 are fixed on both sides of the fermentation tank 1. A placing component 5 is arranged inside the fermentation tank 1, and the placing component 5 includes a placing plate 52. Four groups of placing plates 52 are slidably installed at equal intervals inside the fermentation tank 1, and a pressing plate 51 is arranged at the upper end of the placing plate 52 at the top of the fermentation tank 1. Hollow tubes 53 are slidably inserted at the four corners of the pressing plate 51 and the placing plate 52, and the lower ends of the hollow tubes 53 penetrate into the reflux layer 2. Four leakage grooves 54 are equidistantly arranged on the surface of the hollow tube 53, and a spraying component 6 is arranged at the bottom of the hollow tube 53 at the leakage groove 54. The spraying component 6 includes a rotating ring 61. The rotating ring 61 is rotationally and sealingly installed on the surface of the hollow tube 53 at the bottom of the leakage groove 54 through a bearing, and a vertical tube 44 is inserted into the hollow tube 53. Spherical nozzles 62 are equidistantly arranged on the surface of the rotating ring 61, and the spherical nozzles 62 are connected to the vertical tube 44. The top of the vertical tube 44 is connected to the liquid storage tank 4. A driving component 3 is arranged at the upper end of the top plate 11. The driving component 3 includes a second gear 34. The top of the vertical tube 44 passes through the top plate 11 through a bearing in a rotating manner, and the second gear 34 is sleeved on the outer wall of the vertical tube 44 passing through. When using the device, open the top plate 11, stack the radishes on each placing plate 52, then seal the top plate 11, spray brine on the radishes on each placing plate 52 through the liquid storage tank 4 for pickling. After a period of time, by moving the placing plate 52, the brine flows back into the liquid storage tank 4 through the leakage groove 54, and the radishes are rinsed with clean water, so as to reduce the salt content before preparing pickles for the radishes, making the treatment effect more efficient and uniform.

[0033] In this embodiment, a drain pipe 21 is arranged on one side of the reflux layer 2, and both ends of the reflux layer 2 are communicated with the liquid storage tank 4 through a water pump and a pipeline. Two conveying pipes 41 are fixed on the top of the liquid storage tank 4. The top of the vertical tube 44 is rotationally installed through a bearing with a connecting pipe 43, and a connecting flange 42 is installed between the connecting pipe 43 and the conveying pipe 41. The brine flowing back from the vertical tube 44 is sent into the reflux layer 2 and then returned to the liquid storage tank 4, and it can be sent into the vertical tube 44 for spraying through the conveying pipe 41 again. The conveying pipe 41 is fixedly installed with the connecting pipe 43 through the connecting flange 42, which is convenient for disassembly.

[0034] In this embodiment, the driving assembly 3 further includes a gear ring 33. A gear ring 33 is rotatably mounted on the top of the top plate 11 between four second gears 34 through bearings, and the gear ring 33 is meshed with the second gears 34. A motor 31 is fixedly mounted on the outside of the top plate 11 through a mounting frame, and a first gear 32 is fixed to the output end of the motor 31. The first gear 32 is meshed with the gear ring 33. When the motor 31 is turned on, the first gear 32 rotates and meshes with the gear ring 33, and the gear ring 33 meshes with the four groups of second gears 34 to drive the four groups of vertical pipes 44 to rotate, so as to spray brine or clean water to make the distribution uniform.

[0035] In this embodiment, heat-insulating layers 14 are provided on the inner walls around the fermentation tank 1, and a temperature control board 15 is installed in the heat-insulating layer 14. Temperature sensors and humidity sensors are arranged inside the fermentation tank 1. The temperature control board 15 has the same refrigeration and heating principles as those of the existing air conditioner. Through the heat transfer of the heat-insulating layer 14 to the inside of the fermentation tank 1, combined with the layered placement of the Tibetan turnips, it is more convenient to adjust the fermentation temperature of the Tibetan turnips, and the Tibetan turnips are heated more evenly.

[0036] In this embodiment, a pull rod 13 is fixed at the center of the top of the top plate 11. The lower end of the pull rod 13 is fixedly connected to the bottommost placing plate 52, and a pull ring is arranged at the upper end of the pull rod 13. Pressing rods 12 are slidably inserted on both sides of the pull rod 13 at the upper end of the top plate 11, and the bottom of the pressing rods 12 is fixedly connected to a pressing plate 51. Second springs 71 are fixed at the four sides between the adjacent placing plates 52 and the pressing plate 51. A corrugated pipe 7 is fixed on the periphery of the second spring 71, and both ends of the corrugated pipe 7 are fixedly connected to the corresponding placing plate 52 or the pressing plate 51. After the connecting pipe 43 is separated from the conveying pipe 41, the top plate 11, the pressing plate 51 and the placing plate 52 can be pulled out of the fermentation tank 1 through the pull rod 13, which is convenient for taking out the pickled Tibetan turnips. Each group of placing plates 52 is connected by a strong second spring 71. When the pressing rod 12 is pressed, the pressing plate 51 moves downward to layer by layer extrude the Tibetan turnips on the placing plate 52 for desalting treatment and compress the second spring 71 to make them close to each other, improving the desalting effect. The corrugated pipe 7 outside the second spring 71 can prevent the Tibetan turnips from getting stuck inside the second spring 71 when the second spring 71 expands and contracts, affecting the elasticity.

[0037] In this embodiment, the spraying assembly 6 further includes a horizontal pipe 63. A horizontal pipe 63 is fixed at the position of the vertical pipe 44 corresponding to the spherical nozzle 62. The other end of the horizontal pipe 63 is slidably and sealingly inserted with a telescopic pipe 67, and the other end of the telescopic pipe 67 is fixedly connected to the rear end of the spherical nozzle 62. A first spring 66 is sleeved on the outer surface of the telescopic pipe 67, and both ends of the first spring 66 are fixedly connected to the rear end of the spherical nozzle 62 and the horizontal pipe 63 respectively. A nozzle 64 is provided at the front end of the spherical nozzle 62. A plug 65 is fixed inside the horizontal pipe 63, and the plug 65 penetrates into the spherical nozzle 62. The size of the plug 65 is the same as that of the nozzle 64. The brine or clean water in the liquid storage tank 4 is transported to the inside of each horizontal pipe 63 through the water pump via the delivery pipe 41, the connecting pipe 43 and the vertical pipe 44. Under normal conditions, the placement plate 52 shields the leakage groove 54. At this time, the spherical nozzle 62 extends out of the rotating ring 61, the nozzle 64 is open, and the liquid in the horizontal pipe 63 is sent out through the telescopic pipe 67 and the spherical nozzle 62. Cooperating with the driving assembly 3 to drive the rotation of the vertical pipe 44, the liquid is evenly sprayed on the surface of the yacon from the four corners of the placement plate 52, making the flushing or brine soaking more sufficient. When the placement plate 52 moves downward along the hollow pipe 53, the leakage groove 54 is opened, and the placement plate 52 squeezes the spherical nozzle 62 to retract it into the rotating ring 61. The telescopic pipe 67 compresses the spring and retracts into the horizontal pipe 63, and the plug 65 is inserted into the socket to seal the spherical nozzle 62, which is convenient for the placement plate 52 to compress for desalination (during this process, seals need to be provided for the connection between the placement plate 52 and the vertical pipe 44, and the connection between the horizontal pipe 63 and the telescopic pipe 67 to ensure the sealing performance).

[0038] When using the device, open the top plate 11, place the radish roots on each layer of the placement plate 52, then seal the top plate 11, and spray brine on the radish roots on each layer of the placement plate 52 for pickling through the liquid storage tank 4. Start the motor 31 to drive the first gear 32 to rotate and engage with the gear ring 33. The gear ring 33 engages with four groups of second gears 34 to drive the four groups of vertical pipes 44 to rotate, for spraying brine or clear water. After a period of time, by moving the placement plate 52, the brine flows back into the liquid storage tank 4 through the leakage trough 54, and rinses the radish roots with clear water, so as to perform the treatment of reducing salt content before pickling the radish roots, making the treatment effect more efficient and uniform. Under normal conditions, the placement plate 52 blocks the leakage trough 54. At this time, the spherical nozzle 62 extends out of the rotating ring 61, and the nozzle 64 is open. The liquid in the horizontal pipe 63 is sent out through the telescopic pipe 67 and the spherical nozzle 62. Cooperating with the driving assembly 3 to drive the rotation of the vertical pipe 44, it is thus evenly sprayed on the surface of the radish roots from the four corners of the placement plate 52, making the rinsing or brine soaking of the radish roots more sufficient. When the placement plate 52 moves downward along the hollow pipe 53, the leakage trough 54 opens, and the placement plate 52 squeezes the spherical nozzle 62 to retract it into the rotating ring 61. The telescopic pipe 67 compresses the spring and retracts into the horizontal pipe 63, and the plug 65 is inserted into the socket to seal the spherical nozzle 62, facilitating the compression and desalting of the placement plate 52. After the connecting pipe 43 is separated from the conveying pipe 41 through the pull rod 13, the top plate 11, the pressing plate 51 and the placement plate 52 can be pulled out of the fermentation tank 1, facilitating the removal of the pickled radish roots. Each group of placement plates 52 is connected by a strong second spring 71. When pressing the pressing rod 12, the pressing plate 51 moves downward, layer by layer squeezing the radish roots on the placement plate 52, performing desalting treatment on them, and compressing the second spring 71 to make them close to each other, improving the desalting effect.
