A heating device for fermented lactic acid bacteria sauerkraut

Abstract

This utility model discloses a heating device for fermenting and preparing lactic acid bacteria sauerkraut, including a fermentation box with a hinged top cover. A heating mechanism is installed inside the fermentation box, and a partition frame is fixedly installed at the bottom of the inner cavity. An upper pressure plate and a lower support plate are slidably installed on the inner surface of the partition frame. Lifting mechanisms are provided on both sides of the partition frame, and hoisting mechanisms are provided on the upper surfaces of both sides of the upper pressure plate. This utility model utilizes the hoisting mechanisms. After fermentation, the upper pressure plate on top of the sauerkraut is lifted by the lifting mechanism, and then the hoisting mechanisms on both sides of the top of the upper pressure plate are activated: a motor drives a worm gear to rotate, which in turn drives a meshing worm wheel to rotate, causing the shaft in the middle of the worm wheel to rotate along the top of the support, simultaneously driving the two winding rollers at both ends to rotate. The steel wire rope outside the winding rollers winds up, pulling the lower support plate upwards along the partition frame, assisting in scooping up the sauerkraut and hanging it to drain, improving operational convenience.

Description

Technical Field

[0001] This utility model relates to the field of sauerkraut preparation technology, and more specifically, to a heating device for fermenting and preparing lactic acid bacteria sauerkraut. Background Technology

[0002] Lactic acid bacteria sauerkraut is a traditional fermented vegetable prepared through natural fermentation. It uses fresh cabbage and other vegetables as raw materials. After being cut and salted, the vegetables undergo anaerobic fermentation using lactic acid bacteria attached to the surface of the plants. During the process, the lactic acid bacteria metabolize sugars to produce organic acids such as lactic acid and acetic acid, as well as flavor substances, resulting in a sour and crisp taste.

[0003] A search revealed CN222210796U, which discloses a heating device for fermenting and preparing lactic acid bacteria sauerkraut. The specification states: This utility model provides a heating device for fermenting and preparing lactic acid bacteria sauerkraut. During the sauerkraut fermentation process, the sauerkraut water inside the container can be directly heated, ensuring even heating and improving the fermentation quality. The device can prevent the sauerkraut from floating during fermentation by pressing it down, or it can completely submerge the sauerkraut in the juice, ensuring uniform fermentation and reducing air movement within the sauerkraut. This prevents excessive air bubbles in the juice, which could cause the sauerkraut soup to spoil.

[0004] However, this sauerkraut preparation device still has certain limitations in practical use. Specifically, the above-mentioned technical solution uses the synergistic action of structures such as pressure plates and rotating wheels to press the sauerkraut, ensuring that it is completely submerged in the fermentation brine, thereby improving the quality of the finished product. However, when the sauerkraut needs to be drained and packaged for refrigeration after fermentation, the fixed structures such as the pressure plates make it difficult to fully remove the sauerkraut from the edge areas of the device, resulting in inconvenience in operation and affecting actual production efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a heating device for fermenting and preparing lactic acid bacteria sauerkraut, so as to solve the problem that in some sauerkraut preparation devices in the prior art, the sauerkraut is submerged in fermentation by a pressure plate, but the pressure plate structure hinders the operation of taking out the sauerkraut after fermentation, which affects the convenience of use.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a heating device for fermenting and preparing lactic acid bacteria sauerkraut, comprising...

[0007] A fermentation box, the top of which is hinged with a top cover, the interior of which is equipped with a heating mechanism, the bottom of which is fixedly installed with a partition frame, the inner surface of which is slidably installed with an upper pressure plate and a lower support plate, the left and right sides of which are equipped with lifting mechanisms, and the upper surfaces of the left and right sides of the upper pressure plate are equipped with hoisting mechanisms.

[0008] The hoisting mechanism includes a support frame. The bottom of the support frame is fixedly installed on the upper surface of the side of the upper pressure plate. Both ends of the support frame are rotatably mounted with take-up rollers. A shaft is fixedly installed in the middle of the two take-up rollers. A motor is fixedly installed on the upper surface of the middle part of the support frame. A worm gear is fixedly sleeved on the output end of the motor. A worm wheel meshes with the outer edge of the worm gear. The middle part of the worm wheel is fixedly installed with the middle part of the shaft. A wire rope is connected to the outside of the take-up rollers. The bottom end of the wire rope is fixedly connected to the upper surface of the lower support plate.

[0009] The heating mechanism includes a water tank, with one side of the back of the water tank fixedly installed on one side of the front of the fermentation tank. A heater is fixedly installed at the bottom of the water tank, and a water pump is fixedly installed on the upper surface of the water tank. A circulation pipe is fixedly installed at the top of the water pump. The circulation pipe is located outside the partition frame, and its end away from the water pump is connected to the inside of the water tank. A connecting pipe is fixedly installed on the side of the water pump, and the bottom end of the connecting pipe is fixedly installed to the top of the water tank.

[0010] The lifting mechanism includes two fixed blocks. The surfaces of both fixed blocks are fixedly installed to the sides of the partition frame. A motor is fixedly installed on the inner surface of one fixed block. A shaft is fixedly sleeved at the output end of the motor. Gears are fixedly sleeved on the outer surfaces of both ends of the shaft. The gears are rotatably installed inside the fixed block and mesh with a rack on their outer edges. The outer surface of the rack is slidably installed with the inner surface of the fixed block. A connecting rod is fixedly installed on the side of the rack away from the gear. The outer surface of the connecting rod is slidably installed with the inner wall of the partition frame side. The top of the connecting rod is fixedly installed with the side of the upper pressure plate.

[0011] Auxiliary displacement mechanisms are fixedly installed on the surfaces at the four corners of the bottom of the fermentation tank.

[0012] The auxiliary displacement mechanism includes a cover, the side edges of which are fixedly installed to the surface of the fermentation chamber. A pulley is provided inside the cover, and a sleeve is fixedly installed on the top of the pulley. The outer surface of the top and the outer surfaces of the bottom two ends of the sleeve are slidably installed with the inner surfaces of the top and sides of the cover, respectively. A threaded rod is threadedly connected to the inner surface of the sleeve. A connecting plate is rotatably installed on the top of the threaded rod, and a knob is fixedly installed on the top of the threaded rod. The side edges of the connecting plate are fixedly installed to the surface of the fermentation chamber.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In the above scheme, a hoisting mechanism is installed. After fermentation, the upper pressure plate on top of the sauerkraut is lifted by the lifting mechanism, and then the hoisting mechanisms on both sides of the top of the upper pressure plate are activated: motor two drives the worm gear to rotate, which in turn drives the meshing worm wheel to rotate, causing the shaft two in the middle of the worm wheel to rotate along the top of the support, synchronously driving the winding rollers at both ends to rotate. The steel wire rope outside the winding rollers is wound and wound up, pulling the lower support plate to move upward along the partition frame, assisting in picking up the sauerkraut and hanging it to drain, improving the convenience of operation.

[0015] In the above scheme, an auxiliary displacement mechanism is incorporated. When the fermentation tank needs to be moved to a suitable position or cleaning area, the four corner auxiliary displacement mechanisms are adjusted: rotating the knob drives the threaded rod to rotate along the connecting plate, causing the sleeve outside the threaded rod to slide down along the top and sides of the casing, pushing the bottom pulley to extend and contact the placement surface. By adjusting the lifting and lowering of the auxiliary displacement mechanism, the fermentation tank can be moved conveniently and placed stably, enhancing the practicality of the device.

[0024] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0025] As attached Figure 1 To be continued Figure 6 An embodiment of this utility model provides a heating device for fermenting and preparing lactic acid bacteria sauerkraut, including...

[0026] Fermentation box 1, with a top cover 3 hinged to the top of fermentation box 1, a heating mechanism 2 inside fermentation box 1, a partition frame 4 fixedly installed at the bottom of the inner cavity of fermentation box 1, an upper pressure plate 5 and a lower support plate 6 slidably installed on the inner surface of partition frame 4, lifting mechanisms 7 on both the left and right sides of partition frame 4, and hoisting mechanisms 8 on the upper surfaces of both the left and right sides of upper pressure plate 5.

[0027] The hoisting mechanism 8 includes a support 80. The bottom of the support 80 is fixedly installed on the upper surface of the side of the upper pressure plate 5. Both ends of the support 80 are rotatably mounted with take-up rollers 81. The middle of the two take-up rollers 81 is fixedly mounted with a shaft 82. The upper surface of the middle of the support 80 is fixedly mounted with a motor 83. The output end of the motor 83 is fixedly sleeved with a worm gear 84. The outer edge of the worm gear 84 is meshed with a worm wheel 85. The middle of the worm wheel 85 is fixedly installed with the middle of the shaft 82. The outside of the take-up rollers 81 is connected with a wire rope 86. The bottom end of the wire rope 86 is fixedly connected to the upper surface of the lower support plate 6.

[0028] The heating mechanism 2 includes a water tank 20. The back side of the water tank 20 is fixedly installed on the front side of the fermentation box 1. A heater 21 is fixedly installed at the bottom of the water tank 20. A water pump 22 is fixedly installed on the upper surface of the water tank 20. A circulation pipe 23 is fixedly installed at the top of the water pump 22. The circulation pipe 23 is located outside the partition frame 4, and the end away from the water pump 22 is connected to the inside of the water tank 20. A connecting pipe 24 is fixedly installed on the side of the water pump 22, and the bottom end of the connecting pipe 24 is fixedly installed to the top of the water tank 20.

[0029] By setting up the heating mechanism 2, during the heating operation, the heater 21 is first controlled to heat the clean water inside the water tank 20. Then, the water pump 22 is started, so that the hot water inside the water tank 20 flows into the circulation pipe 23 located at the end inside the water tank 20. It circulates in the fermentation tank 1 and exchanges heat with the brine to heat the brine. Finally, it flows back into the water tank 20 through the water pump 22 and the connecting pipe 24 to complete the circulation of clean water.

[0030] The lifting mechanism 7 includes two fixed blocks 70. The surfaces of both fixed blocks 70 are fixedly installed on the side of the partition frame 4. A motor 71 is fixedly installed on the inner surface of one fixed block 70. A shaft 72 is fixedly sleeved at the output end of the motor 71. Gears 73 are fixedly sleeved on the outer surfaces of both ends of the shaft 72. The gears 73 are rotatably installed inside the fixed block 70 and mesh with a rack 74 on their outer edges. The outer surface of the rack 74 is slidably installed on the inner surface of the fixed block 70. A connecting rod 75 is fixedly installed on the side of the rack 74 away from the gear 73. The outer surface of the connecting rod 75 is slidably installed on the inner wall of the side of the partition frame 4. The top of the connecting rod 75 is fixedly installed on the side of the upper pressure plate 5.

[0031] By setting up the lifting mechanism 7, when controlling the lifting of the upper pressure plate 5, the motor 71 can be started, and the shaft 72 fixedly connected to its output end rotates, driving the gear 73 connected at both ends to rotate inside the fixed block 70, driving the meshing rack 74 to move, so that the rack 74 slides along the inner surface of the fixed block 70, and drives the surface-mounted connecting rod 75 to slide along the inner wall of the side of the partition frame 4, further driving the upper pressure plate 5 connected at the top to perform up and down lifting operations.

[0032] Among them, auxiliary displacement mechanisms 9 are fixedly installed on the surfaces of the four corners at the bottom of the fermentation box 1.

[0033] The auxiliary displacement mechanism 9 includes a cover 90, the side edges of which are fixedly installed on the surface of the fermentation box 1. A pulley 95 is provided inside the cover 90, and a sleeve 94 is fixedly installed on the top of the pulley 95. The outer surface of the top and the outer surfaces of the bottom two ends of the sleeve 94 are slidably installed with the inner surfaces of the top and sides of the cover 90, respectively. A threaded rod 93 is threadedly connected to the inner surface of the sleeve 94. A connecting plate 91 is rotatably installed on the top of the threaded rod 93. A knob 92 is fixedly installed on the top of the threaded rod 93. The side edge of the connecting plate 91 is fixedly installed on the surface of the fermentation box 1.

[0034] The working process of this utility model is as follows:

[0035] During the preparation of sauerkraut fermentation, it can be put into the middle of the partition frame 4 installed in the inner cavity of the fermentation box 1, and the sauerkraut is placed on the lower support plate 6 set at the bottom of the partition frame 4. Then, after the sauerkraut is fed, the upper pressure plate 5 can be lowered by the lifting mechanism 7 until it presses down on the top of the sauerkraut, which helps to immerse the sauerkraut in the brine. The brine can also be heated by the heating mechanism 2 to improve the actual sauerkraut fermentation effect.

[0036] After fermentation is complete, the upper pressure plate 5 pressing on top of the sauerkraut can be raised by controlling the lifting mechanism 7. Then, the lower support plate 6 connected to the lifting mechanism 8 on the left and right sides of the top of the upper pressure plate 5 can be adjusted to move upward along the inner surface of the partition frame 4. During operation, the control motor 83 is started, and the worm gear 84 fixedly sleeved at its output end rotates, driving the meshing worm wheel 85 to rotate. This causes the shaft 82 fixedly installed in the middle of the worm wheel 85 to rotate along the inner surface of the top of the bracket 80, and drives the winding roller 81 fixedly sleeved at both ends to rotate. This causes the wire rope 86 connected to the outer surface of the winding roller 81 to gradually wind up to the outside of the winding roller 81, further pulling the connected lower support plate 6 upward. Thus, the sauerkraut located inside the partition frame 4 can be scooped up by the rising lower support plate 6. After the sauerkraut is separated from the brine, it can be suspended and drained for a period of time, improving the convenience of actual sauerkraut preparation and production.

[0037] When it is necessary to move the fermentation box 1 to a suitable fermentation location or to a cleaning area, the auxiliary displacement mechanisms 9 set at the four corners of the fermentation box 1 can be adjusted in sequence. By turning the knob 92, the connected threaded rod 93 is driven to rotate along the inner surface of the connecting plate 91, so that the sleeve 94 threaded to the outer surface of the threaded rod 93 slides down along the top and inner surfaces of the cover 90. This further drives the pulley 95 fixedly installed at the bottom of the sleeve 94 to move down, so that the pulley 95 moves out from inside the cover 90 and contacts the placement surface of the fermentation box 1. Thus, by adjusting the lifting of the auxiliary displacement mechanism 9, the fermentation box 1 can be easily moved or placed stably as needed, improving the practicality of the device.
