Description

Technical Field

[0001] The present invention belongs to the technical field of pickling equipment, and specifically relates to a storage tank for pickled foods. Background Art

[0002] A food pickling tank is a container used for pickling foods. Its main function is to promote the pickling and preservation of food ingredients. The main functions of a food pickling tank are flavor pickling and fresh-keeping storage. The pickling tank can hold pickling liquids such as brine, sauces, spices, etc., allowing the food ingredients to be fully immersed in the flavoring liquid. The pickling tank has a sealing property, which can effectively prevent the entry of air and bacteria and extend the fresh-keeping period of the food ingredients.

[0003] A Chinese patent with the publication number CN220088493U discloses a food pickling tank, which includes a pickling tank body.

A sealing cover is movably inserted into the top of the docking ring. A limiting disk is fixedly arranged on the top of the sealing cover. An upper guide groove is opened on the bottom surface of the limiting disk. A liquid discharging component for replacing the sealing water of the pickling tank is arranged at the edge position of the side surface of the horizontal rod; by fixedly arranging a limiting disk on the side surface of the top cover and arranging a liquid discharging component between the limiting disk and the top cover, the liquid discharging component can utilize the siphon principle to repeatedly discharge the sealing water at the top of the pickling tank without pouring the pickling tank, which can completely avoid the problems that when the pickling tank is large in volume and weight, it is time-consuming and laborious for workers to adopt the method of pouring the pickling tank to release the sealing water at the top, and the possibility of the pickling tank falling and breaking due to pouring is greatly increased.

[0019] In order 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 implementation manners.

[0020] As Figures 1 to 5As shown in the figure, a pickled food storage tank according to an embodiment of the present invention includes: an outer tank 1, with an inner tank 3 fixedly connected to its inner wall; a stirring mechanism disposed inside the inner tank 3; a shaking mechanism disposed outside the outer tank 1; the stirring mechanism includes a rotating seat 31 rotatably connected to the inner wall of the bottom of the inner tank 3, the top of the rotating seat 31 is fixedly connected with a rotating rod 32, four partition plates 33 are fixedly arranged in a circumferential arrangement on the outer wall of the rotating rod 32, and the bottom of the partition plate 33 cooperates with the rotating seat 31; a connecting mechanism is provided at the top of the rotating rod 32; the shaking mechanism includes an annular plate 11 fixedly connected to the outer wall of the outer tank 1; a base 2 is provided below the outer tank 1; four sliding columns 12 are fixedly connected to the bottom of the annular plate 11; the sliding columns 12 are all slidably connected to the base 2, and first springs 13 are arranged on the outer sides of the sliding columns 12, and the tops of the first springs 13 are fixedly connected to the bottom of the base 2; a rotating plate 21 is rotatably connected to the middle of the base 2; four triangular blocks 14 are fixedly connected to the top of the rotating plate 21; four support columns 16 are fixedly connected to the bottom of the annular plate 11, and rollers 15 are installed at the bottoms of the support columns 16; a driving mechanism is provided at the bottom of the rotating plate 21.

[0021] In the prior art, the pickling tank is just a simple tank. After the food is stored in the tank for a period of time, its pickling materials all settle at the bottom, and the pickling liquid is not evenly distributed, resulting in the food not being evenly pickled, thus affecting the taste of the food; and during the static process, the penetration of the pickling liquid is slow, resulting in low pickling efficiency of the food. When the stirring mechanism and the shaking mechanism provided by the present invention are in use, the stirring and shaking mechanisms work simultaneously. Stirring can make the pickling liquid form a circulating flow inside the container, bringing the pickling liquid to every corner, while shaking can further promote the movement of the pickling liquid in the horizontal and vertical directions, ensuring full contact between the food and the pickling liquid, achieving more comprehensive coverage, and improving the uniformity of pickling; at the same time, through stirring, the components in the pickling liquid can be transferred to the surface of the food faster, and the impact force and friction force generated by shaking can break the boundary layer on the surface of the food, making the components in the pickling liquid more easily penetrate into the interior of the food, thereby increasing the pickling speed. During the working process, it is connected to the rotating rod 32 through a connecting mechanism to drive the rotating rod 32 to rotate. When the rotating rod 32 rotates, it drives the partition plate 33 and the rotating seat 31 to rotate. The bottom of the pickling liquid is stirred and mixed through the rotating seat 31 to prevent the pickling materials from depositing at the bottom of the pickling liquid; the pickling liquid and the food are driven to rotate through the partition plate 33, thereby promoting the flow of the pickling liquid and enabling the components in the pickling liquid to be transferred to the food surface faster; by driving the rotating plate 21 to rotate, the rotating plate 21 drives the triangular block 14 to rotate. When the triangular block 14 rotates past the roller 15, when the triangular block 14 rotates away from the roller 15, the roller 15 drops from the top of the triangular block 14, and the outer tank 1 completes one shaking drive under the drive of the annular plate 11. Under the action of the first spring 13, the outer tank 1 is buffered. The impact force and frictional force generated by the shaking can destroy the boundary layer on the surface of the food, making it easier for the components in the pickling liquid to penetrate into the food interior; Combining stirring and shaking together can not only improve the pickling uniformity, but also make the chemical components in the pickling liquid more uniform, increase the collision probability between reactants, thereby promoting the progress of chemical reactions and accelerating the pickling process; in addition, stirring and shaking help to discharge the air inside the food, reduce oxidation reactions, maintain the tenderness and taste of the food; at the same time, it reduces problems such as deformation and breakage caused by long-term soaking or single-direction force, and maintains the appearance of the product.

[0022] Such as Figure 5 and Figure 6 As shown, the connecting mechanism includes a cover plate 4. The bottom of the cover plate 4 is fixedly connected with a pressing basket 41, and the bottom of the pressing basket 41 is flush with the top of the partition plate 33; the top of the cover plate 4 is fixedly connected with a second motor 42, and the output shaft of the second motor 42 is fixedly connected with a connecting column 43. The connecting column 43 is rotatably connected to the pressing basket 41, and the bottom of the connecting column 43 is fixedly connected with a connecting block 44; a slot is opened at the top of the rotating rod 32, and the connecting block 44 is matched with the slot; a sealing ring 48 is arranged on the outer wall of the pressing basket 41.

[0023] When the connecting mechanism provided by the present invention is in use, during installation, the cover plate 4 and the pressing basket 41 are tightly pressed inside and outside the inner tank 3, and the connecting block 44 is inserted into the slot; through the cooperation of the connecting block 44 and the slot, the second motor 42 is started. The output shaft of the second motor 42 drives the connecting column 43 to rotate, drives the connecting block 44 to rotate through the connecting column 43, and drives the rotating rod 32 to rotate through the connecting block 44, thereby providing power for the rotation of the partition plate 33; by setting the pressing basket 41, it is convenient to press the top of the food in the pickling liquid to prevent the food from being exposed above the pickling liquid and unable to be pickled; a sealing ring 48 is arranged on the outside of the pressing basket 41 to improve the sealing performance of the inner tank 3.

[0024] Such as Figure 4As shown, the driving mechanism includes an L-shaped plate 25 fixedly connected to the bottom of the base 2. A first motor 24 is fixedly connected to the L-shaped plate 25, and an output shaft of the first motor 24 is fixedly connected to a second gear 23. A first gear 22 is fixedly connected to the bottom of the rotating plate 21, and the first gear 22 meshes with the second gear 23.

[0025] The driving mechanism provided by the present invention is used to drive the rotation of the rotating plate 21 during use. By turning on the first motor 24, the output shaft of the first motor 24 drives the second gear 23 to rotate. The second gear 23 drives the first gear 22 to rotate, and the first gear 22 drives the rotating plate 21 to rotate, realizing the function of driving the rotation of the rotating plate 21.

[0026] As Figure 1 and Figure 7 As shown, two mounting seats 7 are symmetrically and fixedly connected to the side wall of the outer tank 1. Third motors 74 are fixedly connected to the bottoms of the mounting seats 7, and output shafts of the third motors 74 are fixedly connected to reciprocating lead screws 72. The reciprocating lead screws 72 are rotatably connected to the mounting seats 7. Lifting blocks 71 are threadedly connected to the reciprocating lead screws 72, and side walls of the lifting blocks 71 are rotatably connected to the cover plate 4 through rotating shafts. Two guide rods 73 are fixedly connected to the mounting seats 7, and the lifting blocks 71 are slidably connected to the two guide rods 73 on the same side.

[0027] When taking materials, when the cover plate 4 is removed, dust or impurities may fall on it, resulting in the contamination of the cover plate 4. The lifting blocks 71 provided by the present invention are used to drive the movement of the cover plate 4 during use. By turning on the two third motors 74, the output shafts of the third motors 74 drive the lifting blocks 71 to move up and down reciprocally. During the upward movement of the lifting blocks 71, the two lifting blocks 71 drive the cover plate 4 to move upward, away from the inner tank 3, and then the cover plate 4 is rotated to a vertical state for operations such as taking materials or cleaning, preventing the cover plate 4 from being contaminated by dust or foreign objects when removed; during the downward movement of the lifting blocks 71, the two lifting blocks 71 drive the cover plate 4 to move downward and insert into the inner tank 3 for sealing.

[0028] As Figure 1 As shown, two fixing plates 75 are fixedly connected to the tops of the mounting seats 7. Two clamping columns 76 are slidably connected to the two fixing plates 75 on the same side. Second springs 77 are sleeved on the outside of the clamping columns 76. One ends of the second springs 77 are fixedly connected to the fixing plates 75 far from the cover plate 4, and the other ends of the second springs 77 are fixedly connected to bumps at one ends of the clamping columns 76. Card slots 411 are respectively formed at both ends of the cover plate 4 and are respectively matched with the clamping columns 76.

[0029] When the clamping post 76 provided by the present invention is in use, during the process of rotating the cover plate 4, the clamping post 76 needs to be pushed to one side, and the second spring 77 is stretched. When the cover plate 4 rotates to the vertical state, under the action of the second spring 77, the clamping post 76 quickly resets and is inserted into the card slot 411 to fix the cover plate 4, facilitating material taking.

[0030] As Figure 3 and Figure 6 shown, a temperature sensor 45 is fixedly connected to the bottom of the cover plate 4, and a plurality of heating pipes 19 are arranged between the outer tank 1 and the inner wall; a second side plate 6 is fixedly connected to the side wall of the outer tank 1; a refrigerator 61 is fixedly connected to the top of the second side plate 6, and an air pipe 62 is arranged at the output end of the refrigerator 61. One end of the air pipe 62 penetrates the outer tank 1 and is connected and fixed to the inner tank 3; both the heating pipes 19 and the refrigerator 61 are electrically connected to the temperature sensor 45.

[0031] The temperature sensor 45 provided by the present invention is used to monitor the temperature inside the inner tank 3 during use. By setting the temperature required for food pickling, the temperature sensor 45 transmits the monitored temperature data to the heating pipes 19 and the refrigerator 61. When the temperature is lower than the threshold value, the heating pipes 19 are energized to heat the inner tank 3; when the temperature is higher than the threshold value, the refrigerator 61 cools down, and the cold air is conveyed to the inner tank 3 through the air pipe 62 to cool the inner tank 3; thus, a relatively stable target temperature range is maintained, forming an automated temperature control system to ensure that the temperature of the inner tank 3 is in a compliant state.

[0032] As Figure 3 and Figure 6 shown, a pressure sensor 46 is fixedly connected to the inner wall of the top of the cover plate 4; a first side plate 5 is fixedly connected to the side wall of the outer tank 1 away from the second side plate 6; an air extraction pump 51 is installed at the top of the first side plate 5; a first communication pipe 52 is arranged at the output end of the air extraction pump 51. One end of the first communication pipe 52 penetrates the outer tank 1 and is connected and fixed to the inner tank 3; the input end of the air extraction pump 51 is connected to a second communication pipe 53 through a flange; an exhaust pipe 49 is connected and fixed to the cover plate 4, and a solenoid valve is arranged on the exhaust pipe 49. Both the solenoid valve and the air extraction pump 51 are electrically connected to the pressure sensor 46.

[0033] The pressure sensor 46 provided by the present invention is used to monitor the pressure inside the inner tank 3 during use. The pressure sensor 46 transmits the detected pressure data to the air extraction pump 51 and the solenoid valve. When the pressure sensor 46 monitors that the internal pressure is lower than the set value, the air extraction pump 51 can inflate the inner tank 3 according to the instruction; when the pressure sensor 46 monitors that the internal pressure is higher than the set value, the solenoid valve opens for exhaust to maintain the internal pressure of the device within the preset pressure range.

[0034] As Figure 2 and Figure 6 shown, a water level gauge 47 is fixedly connected to the inner wall of the top of the cover plate 4. A liquid inlet pipe 410 is fixedly connected and communicated with the top of the cover plate 4, and a valve is provided on the liquid inlet pipe 410. A liquid discharge pipe 17 is fixedly connected and communicated with the bottom of the inner tank 3, and a control valve 18 is provided on the liquid discharge pipe 17.

[0035] The water level gauge 47 provided by the present invention is used to monitor the water level inside the inner tank 3 during use. Before pickling, if it is detected that the water level is low, it may cause the upper-layer food not to be soaked in the pickling liquid, and pickling liquid needs to be added through the liquid inlet pipe 410. When it is necessary to drain the liquid in the inner tank 3, the control valve 18 is opened, and the liquid will flow out along the liquid discharge pipe 17.

[0036] Working principle: During the working process, the second motor 42 is started. The output shaft of the second motor 42 drives the connecting column 43 to rotate. The connecting column 43 drives the connecting block 44 to rotate. The connecting block 44 drives the rotating rod 32 to rotate. When the rotating rod 32 rotates, it drives the partition plate 33 and the rotating seat 31 to rotate. The bottom of the pickling liquid is stirred and mixed through the rotating seat 31 to prevent the pickling materials from depositing at the bottom of the pickling liquid. The pickling liquid and the food are driven to rotate through the partition plate 33, thereby promoting the flow of the pickling liquid and enabling the components in the pickling liquid to be transferred to the surface of the food faster. By starting the first motor 24, the output shaft of the first motor 24 drives the second gear 23 to rotate. The second gear 23 drives the first gear 22 to rotate. The first gear 22 drives the rotating plate 21 to rotate. The rotating plate 21 drives the triangular block 14 to rotate. The triangular block 14 passes by the roller 15 during rotation. When the triangular block 14 rotates away from the roller 15, the roller 15 drops from the top of the triangular block 14. The outer tank 1 completes a shaking under the drive of the annular plate 11. Under the action of the first spring 13, the outer tank 1 is buffered. The impact force and friction force generated by the shaking can destroy the boundary layer on the surface of the food, making it easier for the components in the pickling liquid to penetrate into the interior of the food. Combining stirring and shaking can not only improve the pickling uniformity, but also make the chemical components in the pickling liquid more uniform, increase the collision probability between reactants, thereby promoting the progress of the chemical reaction and accelerating the pickling process. In addition, stirring and shaking help to discharge the air inside the food, reduce the oxidation reaction, maintain the tenderness and taste of the food, and at the same time reduce problems such as deformation and breakage caused by long-term soaking or single-direction force, and maintain the appearance of the product. When taking materials, the cover plate 4 is removed. There may be dust or impurities falling on it, resulting in the contamination of the cover plate 4. By turning on two third motors 74, the output shafts of the third motors 74 drive the lifting blocks 71 to move up and down reciprocally. During the upward movement of the lifting blocks 71, the two lifting blocks 71 drive the cover plate 4 to move upward, away from the inner tank 3. Then the cover plate 4 is rotated to a vertical state. During the rotation of the cover plate 4, the clamping post 76 needs to be pushed to one side, and the second spring 77 is stretched. When the cover plate 4 is rotated to the vertical state, under the action of the second spring 77, the clamping post 76 quickly resets and is inserted into the clamping groove 411 to fix the cover plate 4, facilitating material taking and preventing the cover plate 4 from being contaminated by dust or foreign objects when removed. During the downward movement of the lifting blocks 71, the two lifting blocks 71 drive the cover plate 4 to move downward and be inserted into the inner tank 3 for sealing.
