Description

Technical Field

[0001] The invention relates to the technical field of biological fermentation, and in particular to a sampling device capable of extracting fermented bean paste samples. Background Art

[0002] The fermentation of doubanjiang is a process of mixing raw materials such as broad beans, soybeans, and chili peppers with leavening agents such as salt and yeast. After a natural fermentation process, a unique flavor is cultivated. During the fermentation process, microorganisms decompose organic matter, producing rich aroma and flavor components, which enhance the taste and quality of the doubanjiang. The quality of doubanjiang mainly depends on the fermentation process of the doubanjiang. During the fermentation process of the doubanjiang, the staff needs to regularly sample and observe the doubanjiang to judge the fermentation status of the doubanjiang. Currently, most staff usually use a transparent sampling tube to sample and observe the doubanjiang. When sampling the doubanjiang, the staff needs to open the fermentation tank of the doubanjiang and then take the 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 doubanjiang.

[0003] A Chinese patent with the patent publication number CN215767828U discloses a sampling device for a fermenter, relating to the field of biological fermentation technology. The device comprises a fermenter, a sampling box mounted on one side of the outer wall of the fermenter, a lifting mechanism mounted on the fermenter, a sampling tube mounted on the sampling box, one end of the sampling tube extending into the interior of the sampling box, and the other end of the sampling tube extending from the top of the fermenter side wall into the interior of the fermenter, with a telescopic hose connected to one end of the sampling tube inside the fermenter. By sampling the fermentation liquid in the fermenter in layers, the device is more flexible in use. By opening a second valve, high-temperature steam delivered through a steam pipe sterilizes the sampling tube and sampling box. Furthermore, irradiation with an ultraviolet lamp effectively prevents sample contamination and thus affects the test results of the sample.

[0004] However, the above sampling device has the following problems: when sampling, the broad bean paste easily adheres to the inner wall of the sampling tube, and when the next sampling is performed, it is easy to be confused with the broad bean paste adhered to the previous sampling, thereby causing inaccurate test results.

DETAILED DESCRIPTION

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

[0034] like Figures 1 to 4 As shown, an embodiment of the present invention provides a sampling device for extracting fermented bean paste samples, including a fermentation tank 1, a feed pipe 2 provided at the top of the fermentation tank 1, a discharge pipe 3 provided at the bottom, and a connection box 11 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 connection box 11 is hollow inside and has an opening on the front side. The front side of the connection box 11 is hinged with a door panel for opening and closing the opening. A sampling mechanism 4 is provided in the connection box 11. In this embodiment, there is one connection box 11 and one corresponding sampling mechanism 4. In other embodiments of the present invention, there can be two connection boxes 11, and the number of sampling mechanisms 4 is equal to the number of connection boxes 11. The two connection boxes 11 are set at different heights to facilitate the sampling mechanism 4 to extract two samples at different heights, thereby accurately reflecting the quality problems of the bean paste during the fermentation process. In order to facilitate the disinfection of the interior of the connection box 11, a disinfection lamp 13 is provided on the top inner wall of the connection box 11. The disinfection lamp 13 adopts an ultraviolet disinfection lamp, which is electrically connected to an external power supply via a cable.

[0035] Specifically, the sampling mechanism 4 includes a sample box 41 installed on the inner bottom wall of the connecting box 11, and a plurality of mounting blocks 12 are provided on the inner bottom wall of the connecting box 11. A mounting 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 distributed in a rectangular shape. A mounting cavity matching the sample box 41 is formed between the four mounting blocks 12, which is convenient for placing and removing the sample box 41; a fixed cylinder 42 is provided on the outer wall of the fermentation tank 1 and connected to the interior thereof, the fixed cylinder 42 is located in the connecting box 11 and is vertically connected to the outer wall of the fermentation tank 1, and a through hole communicating with the fixed cylinder 42 is opened on the fermentation tank 1; a through slot column 43 is slidably provided in the fixed cylinder 42, and the inner diameter of the fixed cylinder 42 is the same as that of the through slot The outer diameters of the columns 43 match, and both are cylindrical in structure. A plurality of sealing rings are provided between the outer wall of the through-slot column 43 and the inner wall of the fixed cylinder 42. At the same time, a rubber sealing ring is provided in an annular shape at the end of the fixed cylinder 42, and the rubber sealing ring is located on the outer wall of the through-slot column 43; the fixed cylinder 42 and the through-slot column 43 are both located above the sample box 41, and a through-slot 431 corresponding to the sample box 41 is provided on the through-slot column 43. When the through-slot column 43 is not moved, the through-slot 431 is located directly above the sample box 41; and a driving assembly is provided on the connecting box 11 and is used to drive the through-slot column 43 to slide along the fixed cylinder 42 and take samples. A pushing mechanism 5 is provided in the connecting box 11 for pushing the sample remaining on the inner wall of the through-slot 431 on the through-slot column 43 into the sample box 41. The driving component drives the through-slot column 43 to slide inward along the fixed cylinder 42, and the through-slot column 43 slides and extends into the fermentation tank 1. The broad-bread paste in the fermentation tank 1 will enter the through-slot 431 of the through-slot column 43, and then the driving component drives the through-slot column 43 to reset, so that the broad-bread paste can be taken out and fall into the sample box 41 below, and then the pushing mechanism 5 is started, and the broad-bread paste remaining on the inner wall of the through-slot 431 is pushed into the sample box 41 by the pushing mechanism 5, thereby greatly reducing the situation of broad-bread paste adhering to the inner wall of the through-slot 431, and can effectively avoid confusion with the broad-bread paste adhered to the previous sampling, thereby improving the accuracy of subsequent test results.

[0036] The drive assembly includes a T-shaped column 44 that slides transversely through the side wall of the connection box 11 and is connected to the through-slot column 43. The side wall of the connection box 11 is provided with a through hole for the rod of the T-shaped column 44 to pass through; and a spring 45 that is arranged between the outer wall of the connection box 11 and the end of the T-shaped column 44. The spring 45 is sleeved on the rod of the T-shaped column 44. The rod diameter of the T-shaped column 44 is smaller than the rod diameter of the through-slot column 43. The end of the through-slot column 43 away from the T-shaped column 44 slides with the fixed cylinder 42. In other embodiments of the present invention, the drive assembly can be configured as an electric telescopic rod structure or a telescopic cylinder, which is fixed to the outer wall of the connection box 11 and corresponds to the through-slot column 43. The telescopic end of the electric telescopic rod or telescopic cylinder passes through the through hole of the side wall of the connection box 11 and is connected to the through-slot column 43, thereby pushing the through-slot column 43 to slide in the fixed cylinder 42. By pressing the end of the T-shaped column 44, the through-slot column 43 can be pushed to slide inward along the fixed tube 42 and sample. After the sampling is completed, the T-shaped column 44 is pulled in the opposite direction, and the through-slot column 43 is easily driven to reset under the elastic force of the spring 45, and the extracted bean paste falls into the sample box 41 below.

[0037] like Figure 4 As shown, the pushing mechanism 5 includes a fixing frame 51 which is arranged horizontally on the inner side wall of the connection box 11 and above the through-slot column 43, and the fixing frame 51 is parallel to the through-slot column 43; an electric push rod 52 is arranged on the top of the fixing frame 51, and the electric push rod 52 is located on the top side of the end of the fixing frame 51 away from the connection box 11. The electric push rod 52 is fixed to the top of the fixing frame 51 by screws, and a through hole is opened on the fixing frame 51 to facilitate the output end of the electric push rod 52 to pass through; and an extension hole is located at the bottom of the fixing frame 51 and is connected to the extension hole of the electric push rod 52. The retracted end is fitted with a circular push plate 53, and the telescopic end of the electric push rod 52 passes through the through hole on the fixing frame 51 and is connected to the top of the circular push plate 53. The circular push plate 53 is located directly above the through slot 431, and the bottom plate of the circular push plate 53 matches the size of the through slot 431. In this embodiment, the bottom plate of the circular push plate 53 is a rectangular structure, and the through slot 431 is a rectangular structure; in other embodiments of the present invention, the bottom plate of the circular push plate 53 can be set to a circular structure, and the corresponding through slot 431 is a circular structure, and no specific limitation is made here.

[0038] Specifically, the pushing mechanism 5 also includes a slide plate 54 that is slidably arranged on the top outside of the fixed frame 51 and parallel to the circular push plate 53. The slide plate 54 is provided with a vertical slide groove that matches the width of the fixed frame 51, and the slide plate 54 is located on the top outside of the fixed frame 51; an arc rod 55 is arranged on the bottom side wall of the slide plate 54 and contacts the side wall of the circular push plate 53, and the arc rod 55 is located on the side of the slide plate 54 close to the circular push plate 53; a return spring 56 is arranged between the top side wall of the slide plate 54 and the inner side wall of the connecting box 11; and a plurality of arc blocks 57 are arranged at intervals on the side wall of the circular push plate 53, and the arc rod 55 is located on the moving path of the arc block 57.

[0039] When the electric push rod 52 pushes the return push plate 53 to move downward, the return push plate 53 extends into the through slot 431 of the through slot column 43 and pushes the bean paste and the like adhered to the inner wall of the through slot 431 into the sample box 41 below; in the process of the return push plate 53 moving downward, the arc block 57 contacts the arc rod 55, and then the arc block 57 pushes the arc rod 55 and the slide plate 54 to move in the direction away from the arc 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 block 57 is no longer in contact with the arc rod 55, the slide plate 54 is pushed to return to its original position under the action of the return spring 56, and then the arc rod 55 is used to knock the side wall of the return push plate 53, causing the return push plate 53 to vibrate. The vibration of the return push plate 53 helps to reduce the adhesion between the inner wall of the through slot 431 and the bean paste, making the residual bean paste easier to be pushed out.

[0040] like Figures 5 to 8 As shown, another embodiment of the present invention also includes a stirring mechanism 6 arranged in the connecting 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, the side wall of the fermentation tank 1 is provided with a mounting hole, a sealed bearing is installed on the mounting hole, and the rotating rod 61 is cooperated with the sealed bearing; a stirring blade 62 is arranged on the outer wall of the rotating rod 61 in the fermentation tank 1, and a driving rod 63 is arranged at one end of the rotating rod 61 away from the stirring blade 62 and parallel to the through-groove column 43, the end of the driving rod 63 away from the rotating rod 61 passes through the side wall of the connecting box 11 and extends to the outside, the driving rod 63 is located between the through-groove column 43 and the fixing frame 51, and the rotating rod 61 is located above the bottom plate of the circular push plate 53; the end of the rotating rod 61 away from the stirring blade 62 passes through the hollow part of the circular push plate 53 and is connected to the driving rod 63. During use, rotating the driving rod 63 can drive the rotating rod 61 to rotate, and then drive the stirring blade 62 to rotate. When the stirring blade 62 rotates, it can 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 broad bean paste smoother during the extraction process of the through-groove column 43, and reducing the difficulty or unevenness of sampling.

[0041] Specifically, the stirring mechanism 6 also includes a telescopic rod 64 arranged transversely on the inner wall of the connecting box 11 and below the driving rod 63. The telescopic rod 64 includes an outer tube and an inner rod slidably arranged in the outer tube. The end of the inner rod extends out of the outer tube and is connected to the inner wall of the connecting box 11. The outer tube serves as the telescopic end of the telescopic rod 64. A fixing ring 65 is provided on the telescopic end of the telescopic rod 64 and located on the outer wall of the through-slot 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 larger than the outer diameter of the through-slot 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 located on the outer wall of the through-slot column 43, the inner wall of the disinfection ring 66 is in contact with the outer wall of the through-slot column 43, and the telescopic rod 64 is located above the through-slot column 43; the outer wall of the driving rod 63 located on the inner wall of the connecting box 11 is provided with an annular reciprocating inclined groove 631, and the telescopic end of the telescopic rod 64 is close to the end top wall of the connecting box 11. A sliding column 67 that slides with the annular reciprocating inclined groove 631 is provided, and the sliding column 67 is located on the top side of the end of the outer tube close to the connecting box 11.

[0042] When the driving rod 63 rotates, the sliding column 67 cooperates with the annular reciprocating inclined groove 631, so that the sliding column 67 pushes the outer tube on the telescopic rod 64 to slide along the inner rod, thereby driving the fixing ring 65 and the disinfection ring 66 to move back and forth 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 circular push plate 53, thereby cleaning and disinfecting the outer wall of the through-groove column 43 and the bottom plate of the circular push plate 53.

[0043] Specifically, the disinfection ring 66 includes a first semicircular block 661 and a second semicircular block 662 opposite the first semicircular block 661. A side of the fixing ring 65 away from the telescopic rod 64 is provided with an annular groove 651 that matches the first semicircular block 661 and the second semicircular block 662. The first semicircular block 661 and the second semicircular block 662 are respectively sleeved with arc-shaped disinfection cotton pads 663 for cleaning the outer wall of the through-channel column 43 and the bottom of the circular push plate 53. The arc-shaped disinfection cotton pads 663 have a semicircular structure and include an arc-shaped cotton sleeve and disinfection cotton pads fixed to the inner side and top of the arc-shaped cotton sleeve. The arc-shaped cotton sleeve has an arc-shaped hole inside that facilitates the passage of the first semicircular block 661 and the second semicircular block 662. The disinfection cotton pads are cotton pads adsorbed with alcohol. In addition, to facilitate wiping the bottom of the bottom plate of the circular push plate 53, the top of the arc-shaped disinfection cotton pads 663 has a rectangular structure and corresponds to the bottom of the upper bottom plate of the circular push plate 53. When the circular push plate 53 is in a stationary state, the top surface of the arc-shaped sterilizing cotton 663 and the bottom surface of the bottom plate of the circular push plate 53 are on the same plane.

[0044] The arc-shaped sterilizing cotton 663 is respectively placed on the first semicircular block 661 and the second semicircular block 662, and then clamped on the annular groove 651 to form a sterilizing ring 66; and the arc-shaped sterilizing cotton 663 is disposable and can be replaced in time after use.

[0045] When in use, when it is necessary to sample the bean paste inside the fermentation tank 1, before pushing the T-shaped column 44, 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 stirs the bean paste above the extraction area of ​​the through-groove column 43, thereby improving the fluidity of the bean paste, making the bean paste smoother during the extraction process of the through-groove column 43, and reducing the difficulty or unevenness of sampling; through the cooperation of the annular reciprocating chute 631 and the sliding column 67, the annular reciprocating chute 631 pushes the sliding column 67 to drive the telescopic end of the telescopic rod 64 to move back and forth, and the telescopic end of the telescopic rod 64 pushes the fixed ring 65 to drive the disinfection ring 66 to move back and forth, so that the arc-shaped disinfection cotton 663 disinfects the surface of the through-groove column 43 and the bottom of the circular push plate 53, which can prevent external bacteria from entering the fermentation tank 1, ensure that the production process of the bean paste is not contaminated by the outside, and ensure the quality and safety of the product.

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

[0047] Start the electric push rod 52, and the telescopic end of the electric push rod 52 pushes the circular push plate 53 downward. The bottom plate of the circular push plate 53 pushes out the remaining bean paste in the through groove 431 and drops it into the sample box 41 below. At this time, the sampling operation of the bean paste is completed. The staff can open the door panel on the connection box 11 and take away the sample box 41, and perform a preliminary wipe and clean on the bottom surface of the bottom plate of the circular push plate 53, and wipe off the adhered bean paste. After wiping, the electric push rod 52 drives the circular push plate 53 to reset. When the circular push plate 53 moves downward, the arc block 57 of the circular push plate 53 pushes the arc rod 55 away from the circular push plate 53, and then pushes the slide plate 54 to slide in the direction away from the circular push plate 53. At this time, the return spring 56 is compressed; when the arc block 57 of the circular push plate 53 is no longer in contact with the arc rod 55, the slide plate 54 is reset under the elastic force of the return spring 56, and then drives the arc rod 55 to reset. When the arc rod 55 is reset, it will collide with the side wall of the circular push plate 53, and the circular push plate 53 will vibrate, which helps to reduce the adhesion between the inner wall of the through groove 431 and the bean paste, making it easier to push out the residual bean paste.
