Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0036] The following is a detailed description of a fermented mash sampler provided in this embodiment, with reference to the accompanying drawings. Figures 1-4 As shown, it includes an inner drill rod 10 and an outer casing 20. The inner drill rod 10 is movably fitted inside the outer casing 20. The upper end of the inner drill rod 10 extends out of the upper end of the outer casing 20 for operation of the extension and retraction of the inner drill rod 10 within the outer casing 20. A drill probe 30 is provided at the lower end of the inner drill rod 10 for drilling the fermentation pile and pushing out the sampled mash. Several circumferentially spaced sampling hooks 40 are provided at the lower end of the outer casing 20.
[0037] In this embodiment, the internal drill rod 10 is movably fitted inside the external sleeve 20, making the two a single integrated component. Compared with the original sampling device, the overall weight of the fermented mash sampler is reduced by more than 35%, making it convenient to carry and operate. Simply operate the internal drill rod 10 to expose the drill probe 30 at the lower end of the internal drill rod 10 into the external sleeve 20. Then, the lower end of the entire sampler can drill into the fermentation pile to the corresponding depth under the action of the drill probe 30. The fermented mash is then sampled through the sampling hook 40 at the bottom of the external sleeve 20. By setting the sampling hook 40, the fermented mash can be removed when the viscosity of the fermentation pile is too high in the later stage, improving the sampling success rate from about 40% to more than 95%. Therefore, the fermented mash sampler of this application is easy to carry and operate, and provides accurate sampling. It can effectively improve the efficiency and accuracy of fermented mash sampling and is suitable for fermented mash sampling work in various fermentation piles.
[0038] Please refer to Figure 1 , Figure 5 as well as Figure 6As shown in this embodiment, it should be noted that an installation sleeve 50 is provided at the upper end of the outer sleeve 20. The installation sleeve 50 is adapted to the upper end of the outer sleeve 20 and is nested within the upper end of the outer sleeve 20, communicating with the interior of the outer sleeve 20. A sleeve handle 60 is connected to the end of the installation sleeve 50 away from the outer sleeve 20. The sleeve handle 60 is perpendicular to the installation sleeve 50, and the upper end of the internal drill rod 10 moves through the sleeve handle 60. Thus, by nesting the installation sleeve 50 within the upper end of the outer sleeve 20, the sleeve handle 60 can be installed on the upper end of the outer sleeve 20, facilitating the operator to apply force to the outer sleeve 20 through the sleeve handle 60, improving operational comfort and stability. At the same time, the upper end of the internal drill rod 10 moves through the sleeve handle 60 without affecting the extension and retraction of the internal drill rod 10 within the outer sleeve 20.
[0039] Please refer to Figure 2 As shown, in some embodiments, a drill rod handle 70 is provided at the upper end of the internal drill rod 10. The use of the drill rod handle 70 makes it convenient for the operator to operate the internal drill rod 10 with force, so that the drill probe 30 at the lower end of the internal drill rod 10 can drill the fermentation pile.
[0040] Please refer to Figure 2 , Figure 6 as well as Figure 7 As shown in this embodiment, it should also be noted that, in order to ensure the accuracy of sampling and accurately determine the sampling position, an elongated hole 21 is provided on the outer sleeve 20 along its length direction. Positioning grooves 22 are respectively provided at both ends of the elongated hole 21 on the outer sleeve 20. The positioning grooves 22 extend radially along the outer sleeve 20 and communicate with the elongated hole 21. Positioning pins 80 are provided on the shaft of the inner drill rod 10, which slide within the elongated hole 21. The positioning pins 80 can be positioned within the positioning grooves 22 at both ends of the elongated hole 21. To ensure the stability of the internal drill rod 10 and prevent it from falling out of the outer sleeve 20, a positioning pin 80 is provided on the internal drill rod 10. The positioning pin 80 is cylindrical and located near the upper end of the internal drill rod 10. The positioning pin 80 can circumferentially position the outer sleeve 20. When the positioning pin 80 is in the elongated hole 21, the internal drill rod 10 can move freely within the outer sleeve 20, which facilitates the drilling probe 30 to drill the fermentation pile and push out the sampled mash. When the positioning pin 80 is in the positioning groove 22, the internal drill rod 10 is fixed in the outer sleeve 20 and will not move. In addition, the length of the elongated hole 21 can be set as needed. Thus, through the combined use of the positioning groove 22 and the positioning pin 80, the precise adjustment and fixation of the position of the internal drill rod 10 within the outer sleeve 20 is achieved, ensuring accurate single sampling volume with a weight error controlled within 6g.
[0041] Please refer to Figure 1 and Figure 4 As shown in this embodiment, it should also be noted that the sampling hooks 40 are set inclined towards the centerline of the outer sleeve 20, and the sampling hooks 40 are arc-shaped pieces. The number of sampling hooks 40 can be multiple; in this embodiment, three are used, and the three sampling hooks 40 are evenly distributed circumferentially at the lower end of the outer sleeve 20. The setting of the sampling hooks 40 increases the stability of the mash during sampling, avoids the mash from scattering during the sampling process, and allows the mash to be removed when the viscosity is too high in the later stage of fermentation. The success rate is increased from about 40% to over 95%.
[0042] In some embodiments, the outer sleeve 20 is provided with depth marking lines (not shown in the figure) along its length, which facilitates the operator to accurately control the sampling depth.
[0043] Please refer to Figures 1-3 As shown in this embodiment, it should also be noted that a rubber ring 31 is provided on the outer periphery of the drill probe 30. The rubber ring 31 fits and seals the inner wall of the outer sleeve 20. By fitting and sealing the inner wall of the outer sleeve 20 with the rubber ring 31, the sealing performance during the sampling process is ensured. At the same time as completing the sampling, it can prevent the slag from entering the inner wall of the outer sleeve 20 above the drill probe 30, reduce contamination, and ensure the accuracy and reliability of the sampling.
[0044] The implementation principle of this embodiment is as follows: When using the fermented mash sampler of this application embodiment, first operate the internal drill rod 10 to extend and retract within the outer sleeve 20 until the positioning pin 80 is aligned with the positioning groove 22 near the lower end of the outer sleeve 20, so that the positioning pin 80 is engaged in the positioning groove 22. At this time, the end of the drill probe 30 at the lower end of the internal drill rod 10 protrudes from the outer sleeve 20. Then, sampling is performed in the following order:
[0045] like Figure 8 As shown, the lower end of the sampler is inserted into the sampling position inside the fermentation pile 90 with the help of the drill probe 30. It can generally be lowered to the bottom of the sampling hook 40, which is 5-10 cm below the top of the fermentation pile 90.
[0046] like Figure 9 As shown, the outer sleeve 20 is then kept still, and the inner drill rod 10 is operated to raise the inner drill rod 10 inside the outer sleeve 20 until the positioning pin 80 is aligned with the positioning groove 22 near the upper end of the outer sleeve 20, so that the positioning pin 80 is engaged in the positioning groove 22 and the inner drill rod 10 is locked in position. At this time, the sampling space 100 is left inside the outer sleeve 20 below the drill probe 30.
[0047] like Figure 10As shown, at this time, the outer sleeve 20 is rotated again, allowing the sampling hook 40 to stir the mash in the fermentation pile 90, while the outer sleeve 20 is slowly moved downwards, and the sampling hook 40 collects the mash that it passes through in the outer sleeve 20.
[0048] like Figure 11 As shown, after the outer sleeve 20 collects the mash inside, the outer sleeve 20 is removed from the fermentation pile 90, and the sampling is completed;
[0049] like Figure 12 As shown, when it is necessary to push out the lees, simply push the inner drill rod 10, and the drill probe 30 at the lower end of the inner drill rod 10 will squeeze the lees collected inside the outer sleeve 20 out of the outer sleeve 20.
[0050] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
