Description

Technical Field

[0001] The present invention relates to the technical field of biological fermentation, and particularly relates to a sampling device for extracting fermented samples of broad bean paste. Background Art

[0002] The fermentation of broad bean paste is to mix raw materials such as broad beans, soybeans, and peppers with fermenting agents such as salt and yeast, and through a natural fermentation process, cultivate a unique flavor. During the fermentation process, microorganisms decompose organic matter, producing rich aroma and flavor components, improving the taste and quality of broad bean paste; the quality of broad bean paste mainly depends on the fermentation process of broad bean paste. During the fermentation process of broad bean paste, workers need to regularly sample and observe the broad bean paste to judge the fermentation state of the broad bean paste. At present, most workers usually use a section of transparent sampling tube to sample and observe the broad bean paste. When sampling the broad bean paste, the worker needs to open the fermentation tank of the broad bean paste and then take a sample. Since sampling needs to be carried out at different time periods, the fermentation tank will be opened every time a sample is taken, which will affect the fermentation effect of the broad bean paste.

[0003] Chinese Patent with Patent Publication No. CN215767828U discloses a sampling device for a fermentation tank, which relates to the technical field of biological fermentation. It includes a fermentation tank, a sampling box is installed on one side of the outer wall of the fermentation tank, a lifting mechanism is installed on the fermentation tank, a sampling tube is installed on the sampling box, one end of the sampling tube extends into the interior of the sampling box, and the other end of the sampling tube extends from the top of the side wall of the fermentation tank into the interior of the fermentation tank. One end of the sampling tube inside the fermentation tank is connected with a telescopic hose. By performing stratified sampling on the fermented liquid in the fermentation tank, it is more flexible to use. When in use, by opening the second valve, high-temperature steam conveyed through the steam pipe disinfects the sampling tube and the sampling box, and through the irradiation of ultraviolet lamps, effectively avoids sample contamination and avoids affecting the test results of the sample.

[0004] However, the above sampling device has the following problems: when sampling, the broad bean paste is easily adhered to the inner wall of the sampling tube. When taking the next sample, it is easy to be confused with the broad bean paste adhered during the previous sampling, resulting in inaccurate test results. Summary of the Invention

[0011] Further, the driving assembly includes a T-shaped column horizontally slidably penetrating the side wall of the connection box and connected to the through-groove column, and a spring arranged between the outer side wall of the connection box and the end of the T-shaped column. The end of the through-groove column away from the T-shaped column is slidably matched with the fixed cylinder.

[0012] Further, a stirring mechanism is also arranged in the connection box;

[0013] The stirring mechanism includes a rotating rod rotatably arranged on the side wall of the fermentation tank and extending into the fermentation tank, stirring blades arranged on the outer wall of the rotating rod in the fermentation tank, and a driving rod arranged at the end of the rotating rod away from the stirring blades and parallel to the through-groove column. The end of the driving rod away from the rotating rod penetrates the side wall of the connection box and extends to the outside. The driving rod is located between the through-groove column and the fixed frame, and the rotating rod is located above the bottom plate of the U-shaped push plate.

[0014] Further, the stirring mechanism further includes a telescopic rod horizontally arranged on the inner side wall of the connection box and located below the driving rod, a fixing ring arranged on the telescopic end of the telescopic rod and on the outer wall of the through-groove column, and a disinfection ring detachably connected to the side of the fixing ring away from the telescopic rod and on the outer wall of the through-groove column. The telescopic rod is located above the through-groove column;

[0015] An annular reciprocating inclined groove is provided on the outer wall of the driving rod located on the inner side wall of the connection box, and a sliding column slidably matched with the annular reciprocating inclined groove is arranged on the top wall of the end of the telescopic end of the telescopic rod close to the connection box.

[0016] Further, the disinfection ring includes a first semi-circular block and a second semi-circular block opposite to the first semi-circular block. An annular groove matching the first semi-circular block and the second semi-circular block is formed on the side of the fixed ring away from the telescopic rod. Arc-shaped disinfection cotton for cleaning the outer wall of the through groove column and the bottom of the return-shaped push plate is sleeved on the first semi-circular block and the second semi-circular block respectively.

[0017] Further, the top of the arc-shaped disinfection cotton is of a rectangular structure and corresponds to the bottom of the upper bottom plate of the return-shaped push plate.

[0018] Further, a plurality of mounting blocks are arranged on the inner bottom wall of the connection box, and a mounting cavity for placing the sample box is formed between all the mounting blocks.

[0019] Further, a disinfection lamp is arranged on the inner top wall of the connection box.

[0020] The present invention has the following beneficial effects:

[0021] 1. For the sampling device for extracting the fermented sample of broad bean paste of the present invention, by setting the sampling mechanism, the through groove column is driven by the driving component to slide inward along the fixed cylinder. The through groove column slides and extends into the fermentation tank, and the broad bean paste in the fermentation tank will enter the through groove of the through groove column. The driving component further drives the through groove column to reset, and the extracted broad bean paste falls into the sample box below. Then, the pushing mechanism is started, and the remaining broad bean paste in the through groove of the through groove column is pushed into the sample box by the pushing mechanism, thereby greatly reducing the situation that broad bean paste adheres to the inner wall of the through groove, effectively avoiding the situation of being confused with the broad bean paste adhered during the previous sampling, and improving the accuracy of the subsequent test results.

[0022] 2. For the sampling device for extracting the fermented sample of broad bean paste of the present invention, by setting the pushing mechanism, the return-shaped push plate is pushed downward by the electric push rod and extends into the through groove of the through groove column, so as to push the broad bean paste adhered to the inner wall of the through groove into the sample box below; through the cooperation of the sliding plate, the arc rod, the return spring and the arc-shaped block, when the return-shaped push plate moves under the push of the electric push rod, the arc-shaped block will push the sliding plate to slide along the fixed frame through the arc rod. At this time, the return spring will be compressed. When the arc-shaped block does not contact the arc rod, it will push the sliding plate to reset under the action of the return spring, and then knock on the side wall of the return-shaped push plate through the arc rod, causing the return-shaped push plate to vibrate. The vibration of the return-shaped push plate helps to reduce the adhesion force between the inner wall of the through groove and the broad bean paste, making the remaining broad bean paste easier to be pushed out.

[0023] 3. The sampling device for the fermented sample of extractable broad bean paste of the present invention is provided with a stirring mechanism. By manually driving the driving rod to rotate, the rotating rod and the stirring blades can be driven to rotate, so as to stir the broad bean paste above the extraction area of the through-groove column, thereby improving the fluidity of the broad bean paste, making the extraction process of the broad bean paste in the through-groove column smoother, and reducing the phenomena of difficult sampling or uneven sampling. After the sampling of the through-groove column is completed, continue to rotate the driving rod. Through the cooperation of the rotating rod, the driving rod, the telescopic rod, the fixing ring, the disinfection ring and the annular inclined groove cylinder, the disinfection ring is driven to reciprocate, so as to wipe and disinfect the outer wall of the through-groove column through the disinfection ring, which is convenient for the next use, ensures that the production process of the broad bean paste is not contaminated externally, and guarantees the quality and safety of the product.

Detailed implementation mode

[0033] The principles and features of the present invention will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0034] As Figures 1 to 4 shown, in an embodiment of the present invention, a sampling device for extracting fermented samples of broad bean paste is provided, including a fermentation tank 1. A feed pipe 2 is provided at the top of the fermentation tank 1, and a discharge pipe 3 is provided at the bottom. A connection box 11 is provided on the outer wall of the fermentation tank 1. The connection box 11 is fixed to the outer wall of the fermentation tank 1 by screws. The inside of the connection box 11 is hollow, and an opening is provided on the front side. A door panel for opening and closing the above-mentioned opening is hinged on the front side of the connection box 11. A sampling mechanism 4 is provided inside the connection box 11; in this embodiment, the connection box 11 is provided with one, and the corresponding sampling mechanism 4 is also provided with one. In other embodiments of the present invention, the connection box 11 can be provided with two, and the number of sampling mechanisms 4 is equal to the number of connection boxes 11; the two connection boxes 11 are arranged at different heights, which is convenient for the sampling mechanism 4 to extract samples at two different heights, so as to accurately reflect the quality problems of broad bean paste during the fermentation process. In order to facilitate the disinfection of the inside of the connection box 11, a disinfection lamp 13 is provided on the inner wall of the top of the connection box 11. The disinfection lamp 13 is an ultraviolet disinfection lamp, which is electrically connected to an external power supply through a cable.

[0035] Specifically, the sampling mechanism 4 includes a sample box 41 installed on the inner bottom wall of the connection box 11. A number of mounting blocks 12 are provided on the inner bottom wall of the connection box 11. An installation cavity for placing the sample box 41 is formed between all the mounting blocks 12. In this embodiment, there are four mounting blocks 12, which are arranged in a rectangular distribution. An installation cavity matching the sample box 41 is formed between the four mounting blocks 12, facilitating the placement and removal of the sample box 41; a fixed cylinder 42 provided on the outer wall of the fermentation tank 1 and communicating with its interior. The fixed cylinder 42 is located inside the connection box 11 and is vertically connected to the outer side wall of the fermentation tank 1. A through hole communicating with the fixed cylinder 42 is opened on the fermentation tank 1; a through groove column 43 slidably arranged inside the fixed cylinder 42. The inner diameter of the fixed cylinder 42 matches the outer diameter of the through groove column 43, and both are of a cylindrical structure. A plurality of sealing rings are provided between the outer wall of the through groove column 43 and the inner wall of the fixed cylinder 42. At the same time, a rubber sealing ring is annularly arranged at the end of the fixed cylinder 42, and the rubber sealing ring is located on the outer wall of the through groove column 43; both the fixed cylinder 42 and the through groove column 43 are located above the sample box 41. A through groove 431 corresponding to the sample box 41 is opened on the through groove column 43. When the through groove column 43 does not move, the through groove 431 is located directly above the sample box 41; and a driving assembly provided on the connection box 11 and used to drive the through groove column 43 to slide inside the fixed cylinder 42 and take samples. A pushing mechanism 5 is arranged inside the connection box 11 and used to push the sample remaining on the inner wall of the through groove 431 on the through groove column 43 into the sample box 41. By driving the driving assembly to drive the through groove column 43 to slide inward along the fixed cylinder 42, the through groove column 43 slides and extends into the fermentation tank 1, and the doubanjiang in the fermentation tank 1 will enter the through groove 431 of the through groove column 43. Then, by driving the driving assembly to drive the through groove column 43 to reset, the doubanjiang can be taken out and fall into the sample box 41 below. Then, the pushing mechanism 5 is started, and the doubanjiang remaining on the inner wall of the through groove 431 is pushed into the sample box 41 by the pushing mechanism 5, thus greatly reducing the situation where the doubanjiang adheres to the inner wall of the through groove 431, effectively avoiding the situation of being confused with the doubanjiang adhered during the previous sampling, and improving the accuracy of the subsequent test results.

[0036] Among them, the driving component includes a T-shaped column 44 that laterally slides through the side wall of the connection box 11 and is connected to the through-groove column 43. A through-hole facilitating the rod portion of the T-shaped column 44 to pass through is provided on the side wall of the connection box 11; and a spring 45 is arranged between the outer side wall of the connection box 11 and the end of the T-shaped column 44. The spring 45 is sleeved on the rod portion of the T-shaped column 44, and the rod diameter of the T-shaped column 44 is smaller than the rod diameter of the through-groove column 43; the end of the through-groove column 43 away from the T-shaped column 44 is in sliding fit with the fixed cylinder 42. In other embodiments of the present invention, the driving component can be set as an electric telescopic rod structure or a telescopic cylinder, which is fixed on the outer side wall of the connection box 11 and corresponds to the through-groove column 43. The telescopic end of the electric telescopic rod or the telescopic cylinder passes through the through-hole on the side wall of the connection box 11 and is connected to the through-groove column 43, thereby pushing the through-groove column 43 to slide in the fixed cylinder 42. Press the end of the T-shaped column 44 to push the through-groove column 43 to slide inward along the fixed cylinder 42 for sampling. After sampling, pull the T-shaped column 44 in the reverse direction. Under the elastic force of the spring 45, it is convenient to drive the through-groove column 43 to reset, and the extracted doubanjiang falls into the sample box 41 below.

[0037] As Figure 4 shown, the pushing mechanism 5 includes a fixed frame 51 horizontally arranged on the inner side wall of the connection box 11 and located above the through-groove column 43, and the fixed frame 51 is parallel to the through-groove column 43; an electric push rod 52 arranged on the top of the fixed frame 51. The electric push rod 52 is located on the top side of the end of the fixed frame 51 away from the connection box 11. The electric push rod 52 is fixed to the top of the fixed frame 51 by screws, and a through-hole facilitating the output end of the electric push rod 52 to pass through is provided on the fixed frame 51; and a U-shaped push plate 53 located at the bottom of the fixed frame 51 and in cooperative connection with the telescopic end of the electric push rod 52. The telescopic end of the electric push rod 52 passes through the through-hole on the fixed frame 51 and is connected to the top of the U-shaped push plate 53. The U-shaped push plate 53 is located directly above the through-groove 431, and the bottom plate of the U-shaped push plate 53 matches the size of the through-groove 431. In this embodiment, the bottom plate of the U-shaped push plate 53 is in a rectangular structure, and the through-groove 431 is in a rectangular structure; in other embodiments of the present invention, the bottom plate of the U-shaped push plate 53 can be set in a circular structure, and the corresponding through-groove 431 is in a circular structure, which is not specifically limited here.

[0038] Specifically, the pushing mechanism 5 further includes a sliding plate 54 slidably arranged on the outer side of the top of the fixed frame 51 and parallel to the U-shaped push plate 53. A vertical sliding groove matching the width of the fixed frame 51 is provided on the sliding plate 54, and the sliding plate 54 is located on the outer side of the top of the fixed frame 51; an arc rod 55 arranged on the bottom side wall of the sliding plate 54 and in contact with the side wall of the U-shaped push plate 53. The arc rod 55 is located on the side of the sliding plate 54 close to the U-shaped push plate 53; a return spring 56 arranged between the top side wall of the sliding plate 54 and the inner side wall of the connection box 11; and a plurality of arc-shaped blocks 57 spaced apart on the side wall of the U-shaped push plate 53. The arc rod 55 is located on the moving path of the arc-shaped blocks 57.

[0039] When the electric push rod 52 pushes the U-shaped push plate 53 to move downward, the U-shaped push plate 53 extends into the through groove 431 of the through groove column 43, and pushes the bean paste adhered to the inner wall of the through groove 431 and the like into the sample box 41 below; during the process of the U-shaped push plate 53 moving downward, the arc-shaped block 57 contacts the arc rod 55, and then the arc rod 55 and the slide plate 54 are pushed to move in a direction away from the arc-shaped block 57 through the arc-shaped block 57. At this time, the slide plate 54 slides along the fixed frame 51, and the return spring 56 is compressed. When the arc-shaped block 57 does not contact the arc rod 55, the slide plate 54 will be pushed to reset under the action of the return spring 56, and then the side wall of the U-shaped push plate 53 is knocked through the arc rod 55, causing the U-shaped push plate 53 to vibrate. The vibration of the U-shaped push plate 53 helps to reduce the adhesion between the inner wall of the through groove 431 and the bean paste, making the remaining bean paste easier to be pushed out.

[0040] As Figures 5 to 8 shown, in another embodiment of the present invention, it further includes a stirring mechanism 6 arranged in the connection box 11; the stirring mechanism 6 includes a rotating rod 61 rotatably arranged on the side wall of the fermentation tank 1 and extending into the fermentation tank 1. An installation hole is provided on the side wall of the fermentation tank 1, and a sealing bearing is installed on the installation hole. The rotating rod 61 is connected in cooperation with the sealing bearing; stirring blades 62 arranged on the outer wall of the rotating rod 61 in the fermentation tank 1, and a driving rod 63 arranged at one end of the rotating rod 61 away from the stirring blades 62 and parallel to the through groove column 43. The end of the driving rod 63 away from the rotating rod 61 penetrates through the side wall of the connection box 11 and extends to the outside. The driving rod 63 is located between the through groove column 43 and the fixed frame 51, and the rotating rod 61 is located above the bottom plate of the U-shaped push plate 53; the end of the rotating rod 61 away from the stirring blades 62 passes through the hollow part of the U-shaped push plate 53 and is connected to the driving rod 63. When in use, rotating the driving rod 63 can drive the rotating rod 61 to rotate, and then drive the stirring blades 62 to rotate. When the stirring blades 62 rotate, they can stir the bean paste above the extraction area of the through groove column 43, thereby improving the fluidity of the bean paste, making the extraction of the bean paste in the through groove column 43 smoother, and reducing the phenomenon of difficult or uneven sampling.

[0041] Specifically, the agitating mechanism 6 further includes a telescopic rod 64 that is horizontally arranged on the inner side wall of the connection box 11 and is located below the driving rod 63. The telescopic rod 64 includes an outer tube and an inner rod that is slidably arranged inside the outer tube. The end of the inner rod extends outside the outer tube and is connected to the inner side wall of the connection box 11. The outer tube serves as the telescopic end of the telescopic rod 64; a fixing ring 65 that is arranged on the telescopic end of the telescopic rod 64 and is located on the outer wall of the through groove column 43. The fixing ring 65 is located at the end of the outer tube away from the inner rod, and the inner diameter of the fixing ring 65 is greater than the outer diameter of the through groove column 43; and a disinfection ring 66 that is detachably connected to the side of the fixing ring 65 away from the telescopic rod 64 and is located on the outer wall of the through groove column 43. The inner side wall of the disinfection ring 66 contacts the outer wall of the through groove column 43, and the telescopic rod 64 is located above the through groove column 43; an annular reciprocating inclined groove 631 is formed on the outer wall of the driving rod 63 located on the inner side wall of the connection box 11. A sliding column 67 that is slidably matched with the annular reciprocating inclined groove 631 is arranged on the top wall of the telescopic end of the telescopic rod 64 close to the connection box 11. The sliding column 67 is located on the top side of the end of the outer tube close to the connection box 11.

[0042] When the driving rod 63 rotates, through the cooperation of the sliding column 67 and the annular reciprocating inclined groove 631, the sliding column 67 pushes the outer tube on the telescopic rod 64 to slide along the inner rod, and then the fixing ring 65 and the disinfection ring 66 can be driven to reciprocate on the outer wall of the through groove column 43. When the disinfection ring 66 moves, it will wipe the outer wall of the through groove column 43, and at the same time, it can also wipe the bottom of the bottom plate of the return-shaped push plate 53, realizing the cleaning and disinfection of the outer wall of the through groove column 43 and the bottom plate of the return-shaped push plate 53.

[0043] Specifically, the disinfection ring 66 includes a first semi-circular block 661 and a second semi-circular block 662 opposite to the first semi-circular block 661. An annular groove 651 that matches the first semi-circular block 661 and the second semi-circular block 662 is formed on the side of the fixing ring 65 away from the telescopic rod 64. Arc-shaped disinfection cotton 663 for cleaning the outer wall of the through groove column 43 and the bottom of the return-shaped push plate 53 is sleeved on the first semi-circular block 661 and the second semi-circular block 662 respectively. The arc-shaped disinfection cotton 663 has a semi-circular structure, which includes an arc-shaped cotton sleeve and disinfection cotton fixed on the inner side and top of the arc-shaped cotton sleeve. The inner part of the arc-shaped cotton sleeve has an arc-shaped hole for the first semi-circular block 661 and the second semi-circular block 662 to pass through. The disinfection cotton is a cotton pad adsorbed with alcohol; and in order to facilitate wiping the bottom of the bottom plate of the return-shaped push plate 53, the top of the arc-shaped disinfection cotton 663 has a rectangular structure and corresponds to the bottom of the top plate on the return-shaped push plate 53. When the return-shaped push plate 53 is in a static state, the top surface of the arc-shaped disinfection cotton 663 is in the same plane as the bottom surface of the bottom plate of the return-shaped push plate 53.

[0044] The arc-shaped disinfection cotton 663 is respectively sleeved on the first semi-circular block 661 and the second semi-circular block 662, and then clamped on the annular groove 651 to form a disinfection ring 66 in combination; and the arc-shaped disinfection cotton 663 is for one-time use and can be replaced in time after use.

[0045] During use, when it is necessary to sample the broad bean paste inside the fermenter 1, before pushing the T-shaped column 44 during sampling of the broad bean paste, the staff manually rotates the driving rod 63, which can drive the rotating rod 61 and the stirring blade 62 to rotate. When the stirring blade 62 rotates, it will stir the broad bean paste above the extraction area of the through groove column 43, thereby improving the fluidity of the broad bean paste, making the extraction of the broad bean paste through the through groove column 43 smoother, and reducing the phenomenon of difficult or uneven sampling; through the cooperation of the annular reciprocating inclined groove 631 and the sliding column 67, the annular reciprocating inclined groove 631 pushes the sliding column 67 to drive the telescopic end of the telescopic rod 64 to reciprocate, and the telescopic end of the telescopic rod 64 pushes the fixed ring 65 to drive the disinfection ring 66 to reciprocate, so that the arc-shaped disinfection cotton 663 disinfects the surface of the through groove column 43 and the bottom of the return-shaped push plate 53, preventing external bacteria from entering the fermenter 1, ensuring that the production process of the broad bean paste is not contaminated externally, and guaranteeing the quality and safety of the product.

[0046] Push the T-shaped column 44 further in the direction of the fermenter 1. At this time, the spring 45 is compressed, and the T-shaped column 44 pushes the through groove column 43 to move inside the fixed cylinder 42 and into the fermenter 1. When the through groove 431 of the through groove column 43 moves into the fermenter 1, the broad bean paste in the fermenter 1 will flow into the through groove 431. Then, pull the T-shaped column 44 in the reverse direction. With the elastic force of the spring 45, the T-shaped column 44 can be pulled to move away from the fermenter 1. The through groove column 43 is reset at this time. The setting of the spring 45 facilitates assisting the through groove column 43 to reset and reduces the pulling force required for its reset; the broad bean paste in the through groove 431 of the through groove column 43 will fall into the sample box 41 below.

[0047] Start the electric push rod 52. The telescopic end of the electric push rod 52 pushes the loop-shaped push plate 53 downward. The bottom plate of the loop-shaped push plate 53 pushes out the remaining broad bean paste in the through groove 431 and falls into the sample box 41 below. At this time, the sampling operation of the broad bean paste is completed. The staff can open the door panel on the connection box 11, take away the sample box 41, and initially wipe and clean the bottom surface of the bottom plate of the loop-shaped push plate 53, and wipe off the adhered broad bean paste. After wiping, the electric push rod 52 drives the loop-shaped push plate 53 to reset. When the loop-shaped push plate 53 moves downward, the arc-shaped block 57 of the loop-shaped push plate 53 will push the arc rod 55 away from the loop-shaped push plate 53, and then push the sliding plate 54 to slide in the direction away from the loop-shaped push plate 53. At this time, the return spring 56 is compressed; when the arc-shaped block 57 of the loop-shaped push plate 53 does not contact the arc rod 55, the sliding plate 54 resets under the elastic force of the return spring 56, and then drives the arc rod 55 to reset. When the arc rod 55 resets, it will impact the side wall of the loop-shaped push plate 53, and the loop-shaped push plate 53 vibrates, which helps to reduce the adhesion between the inner wall of the through groove 431 and the broad bean paste, making the remaining broad bean paste easier to be pushed out.

[0048] After the sampling mechanism 4 finishes sampling, the driving rod 63 can be driven to rotate again, so that the telescopic end of the telescopic rod 64 can push the fixed ring 65 to drive the disinfection ring 66 to move back and forth, and the surface of the through groove column 43 and the bottom of the loop-shaped push plate 53 are wiped and cleaned again through the arc-shaped disinfection cotton 663. After wiping, the disinfection ring 66 is disassembled, and the arc-shaped disinfection cotton 663 is removed. The two semi-circular blocks are clamped into the annular groove 651. Finally, the disinfection lamp 13 is started, the door panel of the connection box 11 is closed, and its interior is disinfected. After each sampling, the used arc-shaped disinfection cotton 663 is disassembled, and before the next sampling, the unused arc-shaped disinfection cotton 663 is installed on the two semi-circular blocks, so as to keep the through groove column 43 and the loop-shaped push plate 53 hygienic.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
