Abstract
Description
Technical Field
[0001] This utility model relates to the field of wine mash sampling technology, and in particular to a sampler. Background Technology
[0002] The brewing process includes the fermentation of the mash, such as pile fermentation and cellar fermentation. The fermentation status of the mash has a significant impact on the alcohol yield and quality during brewing. In order to accurately obtain the mash during pile fermentation or cellar fermentation for the detection and research of its physicochemical and microbiological indicators, a mash sampler is usually used to sample the mash.
[0003] Chinese patent CN206696014U discloses a solid-state fermented mash sampler, comprising an outer tube and a sampling tube movably inserted within the outer tube. The outer tube has a handle and a tapered portion. Several radially outwardly protruding arc-shaped protrusions are arranged on the tube wall from front to back, forming scrapers for scraping mash samples. Arc-shaped sampling openings are provided between the sides of each scraper and the outer tube wall. Several sampling chambers are arranged inside the sampling tube from front to back, corresponding to the positions of the scrapers. Each sampling chamber opens to the side facing the scraper and has partitions on both sides. The sampling tube also has a sampling handle.
[0004] During the sampling process, liquid water in the mash mixed with starch, fine mash particles, etc., can seep into the gap between the outer and inner tubes. Usually, the inner tube needs to be pulled out from the outer tube to clean the stains and sewage between the inner and outer tubes, which is quite troublesome. Utility Model Content
[0005] To address the shortcomings of related technologies, this invention provides a sampler. After sampling, the sampler can be soaked and cleaned with water, allowing water between the outer and inner tubes to flow out easily through the through-hole without needing to detach the inner tube from the outer tube. Furthermore, detaching the tip from the straight tube can further improve the cleaning effect.
[0006] This utility model provides a sampler, including an outer unit and an inner unit; The inner unit includes an inner tube, partitions, and a first handle; multiple partitions are fixed inside the inner tube, forming multiple sampling chambers inside the inner tube, each sampling chamber having an inner sampling port located on the inner tube wall, and the first handle is fixed to the rear end of the inner tube; The outer unit includes an outer tube and a second handle; the outer tube includes a straight tube with external sampling ports corresponding one-to-one with the inner sampling ports, and a tip detachably connected to the front end of the straight tube; the tip has a through hole; the second handle is fixed to the side wall of the rear end of the straight tube; the inner tube rotates inside the outer tube. In some of these embodiments, the tip is connected to a straight pipe thread.
[0007] In some embodiments, the tip includes an integrally formed limiting portion and a threaded portion, the threaded portion being threadedly connected to the inner wall of the straight pipe; the outer diameter of the limiting portion gradually decreases in the direction away from the straight pipe, and the maximum outer diameter of the limiting portion is equal to the outer diameter of the straight pipe.
[0008] In some embodiments, a groove is provided on the end face of the tip near the second handle, and a through hole connects to the groove.
[0009] In some embodiments, the inner tube wall is provided with a sliding groove and a limiting groove located on one side of the sliding groove and communicating with the end of the sliding groove; the sliding groove is located between the first handle and the adjacent sampling chamber; the outer unit also includes a limiting post fixed to the straight tube, the limiting post rotating around the axis of the inner tube in the sliding groove, and the limiting post sliding along the axis of the inner tube in the limiting groove; when the limiting post is located in the limiting groove, the outer sampling port is aligned with the inner sampling port; when the limiting post is located at the end of the sliding groove away from the limiting groove, the outer sampling port is blocked by the inner tube wall.
[0010] In some embodiments, the length of the outer sampling port in the axial direction of the outer tube is greater than the length of the inner sampling port in the axial direction of the inner tube.
[0011] In some embodiments, the inner tube includes a first tube segment and a second tube segment fixedly connected, the first tube segment being located inside the outer tube and the second tube segment being located outside the outer tube, the sampling chamber being located inside the first tube segment, and the sliding groove and the limiting groove being located at the end of the first tube segment near the second tube segment; the first handle is fixed to the second tube segment.
[0012] In some embodiments, the width of the inner sampling port in the radial direction of the inner tube is smaller than the inner diameter of the inner tube.
[0013] In some embodiments, a scraper is fixed at each external sampling port.
[0014] In some embodiments, the scraper is provided with a bevel on the side away from the first handle, and the end of the bevel away from the outer tube axis is inclined toward the first handle.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The tip of the outer tube is detachable and has a through hole, which makes it easy to clean water and contaminants that seep into the gap between the outer tube and the inner tube without having to remove the inner tube from the outer tube.
[0016] 2. When the outer sampling port and the inner sampling port are aligned, the limiting post can enter the limiting groove in a direction parallel to or close to the inner tube axis, so that the limiting post cannot rotate around the inner tube axis, thereby locking the sampling chamber in the open state and preventing the sampling chamber from being closed by external force, resulting in insufficient sampling volume.
[0017] 3. The outer tube has a consistent cross-sectional dimension throughout, with no variation in thickness, making it easier to move the solid mash into and out of the mash pile. At the same time, it does not cause significant damage to the mash pile. Attached Figure Description

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0021] In the description of this utility model, it should be understood that the terms "center", "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0022] The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.
[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0024] like Figure 1-9 As shown in the illustrative embodiment of the sampler provided by this utility model, the sampler includes at least an outer unit and an inner unit; The inner unit includes an inner tube 11, a partition 12 and a first handle 13; multiple partitions 12 are fixed inside the inner tube 11 to form multiple sampling chambers inside the inner tube 11, each sampling chamber having an inner sampling port 1121 located on the inner tube wall, and the first handle 13 is fixed to the rear end of the inner tube 11. The outer unit includes an outer tube 21 and a second handle 22; the outer tube 21 includes a straight tube 211 with an outer sampling port 2111 corresponding to the inner sampling port 1121, and a tip 212 detachably connected to the front end of the straight tube 211; the tip 212 is provided with a through hole 2123; the second handle 22 is fixed to the side wall of the front end of the straight tube 211; the inner tube 11 rotates inside the outer tube 21.
[0025] After sampling, the sampler is soaked and cleaned with water. Water between the outer tube 21 and the inner tube 11 can easily flow out through the through hole 2123 without removing the inner tube 11 from the outer tube 21. The tip 212 is then removed from the straight tube 211 for deep cleaning of the gap between the outer tube 21 and the inner tube 11. After cleaning, the tip 212 is reinstalled into the straight tube 211. Furthermore, the shape of the tip 212 reduces the resistance of the outer tube 21 when inserting into the solid mash pile, helping the sampler to quickly penetrate deep into the solid mash pile.
[0026] In some embodiments, the tip 212 is threaded to the straight tube 211, balancing the speed of assembly and disassembly of the tip 212 and the reliability of the connection. The thread tightening direction is opposite to the rotation direction of the sampler during sampling to prevent the thread from loosening.
[0027] In some embodiments, the tip 212 includes an integrally formed limiting portion 2121 and a threaded portion 2122, the threaded portion 2122 being threadedly connected to the inner wall of the straight tube 211; the outer diameter of the limiting portion 2121 gradually decreases in the direction away from the straight tube 211, and the maximum outer diameter of the limiting portion 2121 is equal to the outer diameter of the straight tube 211.
[0028] The straight pipe 211 has a uniform cross-sectional dimension throughout, with no variation in thickness, making it easier to enter and exit the solid mash pile and preventing significant damage to the pile. Furthermore, the outer wall of the limiting part 2121 smoothly transitions to the outer wall of the straight pipe 211, further reducing the difficulty of the outer pipe 21 entering and exiting the solid mash pile and further minimizing the possibility of damage to the pile.
[0029] In some embodiments, a groove 2124 is provided on the end face of the tip 212 near the second handle 22, and a through hole 2123 connects to the groove 2124. When the tip 212 is located at the bottom of the outer tube 21, the liquid that the sampler seeps into will concentrate in the groove 2124 and flow out of the outer tube 21 through the through hole 2123.
[0030] Furthermore, the groove wall of the groove 2124 away from the second handle 22 is perpendicular to the axis of the tip 212, and the through hole 2123 is opened on the groove wall of the groove 2124 away from the second handle 22. The axis of the through hole 2123 is parallel to the axis of the straight pipe 211, so as to further improve the drainage effect of the tip 212.
[0031] Furthermore, the inner tube 11 has a sliding groove 1122 on its wall and a limiting groove 1123 located on one side of the sliding groove 1122 and connected to the end of the sliding groove 1122; the sliding groove 1122 is located between the first handle 13 and its adjacent sampling chamber; the outer unit also includes a limiting post 23 fixed to the straight tube 211, the limiting post 23 rotates around the axis of the inner tube 11 in the sliding groove 1122, and the limiting post 23 slides along the axis of the inner tube 11 in the limiting groove 1123; when the limiting post 23 is located in the limiting groove 1123, the outer sampling port 2111 is aligned with the inner sampling port 1121, and the limiting post 23 cannot rotate around the axis of the inner tube 11, so as to lock the open state of the sampling chamber and avoid the sampling chamber being closed by external force, resulting in insufficient sampling volume. After sampling is completed, the limiting post 23 retracts back to the slide 1122 and rotates around the axis of the inner tube 11 in the slide 1122. At this time, the outer tube 21 rotates relative to the inner tube 11 to close the sampling chamber and prevent the sample from falling out of the sampling chamber.
[0032] When the limiting post 23 is located at the end of the slide groove 1122 away from the limiting groove 1123, the external sampling port 2111 is blocked by the inner tube 11 wall.
[0033] In some embodiments, the length of the outer sampling port 2111 in the axial direction of the outer tube 21 is greater than the length of the inner sampling port 1121 in the axial direction of the inner tube 11, so that when the limiting post 23 slides in the limiting groove 1123, the inner sampling port 1121 is not blocked by the tube wall of the straight tube 211, thereby eliminating the influence of setting the limiting groove 1123 on the sampling efficiency.
[0034] In some embodiments, the inner tube 11 includes a first tube segment 111 and a second tube segment 112 that are fixedly connected. The first tube segment 111 is located inside the outer tube 21, and the second tube segment 112 is located outside the outer tube 21. The sampling chamber is located inside the first tube segment 111. The sliding groove 1122 and the limiting groove 1123 are located at the end of the first tube segment 111 near the second tube segment 112. The first handle 13 is fixed to the second tube segment 112.
[0035] When assembling and producing the above-mentioned sampler, the first tube segment 111 can be inserted into the outer tube 21 first, and then the limiting post 23 can be inserted into the limiting groove 1123 or the sliding groove 1122 after passing through the outer tube 21. At this time, since the second tube segment 112 has not been installed, the installation of the limiting post 23 can be observed directly. After the limiting post 23 is installed, the first tube segment 111 and the second tube segment 112 are fixedly connected.
[0036] In some embodiments, the width of the inner sampling port 1121 in the radial direction of the inner tube 11 is smaller than the inner diameter of the inner tube 11, and the cross-section of the sampling chamber is larger than a semicircle. During the rotation sampling process, once the mash falls into the sample chamber, it will not easily fall out again.
[0037] In some embodiments, the outer unit also includes a scraper 24, with one scraper 24 fixed at each outer sampling port 2111. When sampling is performed by rotating the sampler clockwise on one side of the sampling opening, the scraper 24 is located on the left side of the sampling chamber, as shown in the figure. When sampling is performed by rotating the sampler counterclockwise, the scraper 24 is located on the right side of the sampling chamber. The scraper 24 has a thin sheet structure to reduce the resistance when the sampler is inserted into the mash. At the same time, when the sampler is pulled out, it will not pull out a large amount of mash, thus minimizing damage to the solid mash pile.
[0038] Furthermore, the scraper 24 is parallel to the axis of the outer cylinder.
[0039] In some embodiments, the scraper 24 is provided with a bevel 241 on the side away from the first handle 13, and the end of the bevel 241 away from the axis of the outer tube 21 is inclined toward the first handle 13 to further reduce the resistance of the scraper 24 entering the solid mash pile.
[0040] Furthermore, the length of the scraper 24 in the axial direction of the outer tube 21 is greater than the length of the outer sampling port 2111 in the axial direction of the outer tube 21.
[0041] In some embodiments, the first handle 13 passes through the inner tube 11, with both ends of the first handle 13 located outside the inner tube 11.
[0042] like Figure 1-9 The diagram shows the structure of the sampler in a preferred embodiment of this invention. The method of using this embodiment is as follows: S1. Hold the second handle with one hand and rotate the first handle counterclockwise with the other hand so that the limiting post touches the end of the slide groove away from the limiting groove. At this time, the sample chamber is completely closed, that is, the inner sampling port and the outer sampling port are completely misaligned.
[0043] S2. Hold the outer tube and the second handle, and insert the sampler horizontally into the mash pile to the required depth.
[0044] S3. Rotate the first handle clockwise until the limiting post touches the other end of the slide groove, and push the first handle forward to make the limiting post engage with the limiting groove. At this time, the sample chamber is fully open.
[0045] S4. Rotate the second handle clockwise to take a sample. Generally, rotate 3-4 times. The mash will fall into the sample chamber due to the accumulation effect of the scraper.
[0046] S5. Pull the first handle backward, then rotate the inner cylinder handle counterclockwise so that the limiting post touches the end of the slide groove away from the limiting groove. At this time, the sample chamber is completely closed.
[0047] S6. Hold the outer tube and the second handle, and pull out the sampler.
[0048] S7. Hold the outer tube with one hand and rotate the first handle clockwise with the other hand to open the sample chamber. Use a spoon or other tools to remove the mash sample from the sample chamber.
[0049] S8. After sampling, stand the sampler upright; the internal wastewater will flow out from the tip through-hole. Clean the sampler; the tip can be removed at this time. After soaking and cleaning, stand the sampler upright; the internal wastewater will flow out from the front end of the straight cylinder. After drying, the tip can be reinstalled.
[0050] Through the description of several embodiments of the sampler of this utility model, it can be seen that the embodiments of the sampler of this utility model have at least one or more of the following advantages: 1. The tip 212 of the outer tube 21 is detachable and has a through hole 2123, which facilitates cleaning water and contaminants that seep into the gap between the outer tube 21 and the inner tube 11 without having to remove the inner tube 11 from the outer tube 21.
[0051] 2. When the outer sampling port 2111 is aligned with the inner sampling port 1121, the limiting post 23 can enter the limiting groove 1123 in a direction parallel to or close to the axis of the inner tube 11, so that the limiting post 23 cannot rotate around the axis of the inner tube 11, thereby locking the open state of the sampling chamber and preventing the sampling chamber from being closed by external force, resulting in insufficient sampling volume.
[0052] 3. The cross-sectional dimensions of the straight pipe 211 of the outer pipe 21 are consistent throughout, with no variation in thickness, making it easier to move in and out of the solid mash pile. At the same time, it will not cause significant damage to the mash pile.
[0053] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0054] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
