Description

Technical Field

[0001] This utility model relates to the field of sampling technology for flavor blending containers, specifically to a retractable sampling device for flavor blending containers. Background Technology

[0002] In the fragrance and flavor industry, fragrance blending is a highly precise and complex process. Its core lies in the accurate mixing of various fragrance raw materials according to a specific formula to obtain a final product with specific aroma characteristics and stability. Throughout the blending process, sampling and analysis are crucial steps, playing an irreplaceable role in ensuring product quality, improving production efficiency, and guaranteeing process stability.

[0003] However, existing sampling processes suffer from problems such as poor sample representativeness, high risk of cross-contamination, and loss of volatile components. This can lead to consequences such as the analysis results not accurately reflecting the true state of the overall sample, the introduction of exogenous pollutants, and the loss of effective components, which negatively impact flavor formulation.

[0004] To address these issues, some solutions have emerged in the industry, such as using fixed-point sealed samplers and stratified sampling with multi-port sidewall connectors. However, these methods have drawbacks, including limited sample representativeness and poor monitoring flexibility. Other methods include using quick-release sampling heads and online sampling, but these are costly and difficult to clean. Still others involve using negative pressure sampling bags, low-temperature ice boxes with metal sampling bottles, and headspace-online sampling valves, but these methods suffer from bag leakage, high modification costs, and significant losses.

[0005] To address the aforementioned issues, there is an urgent need for a device that enables scalable and adjustable stratified sampling, fully enclosed sampling, and independent control of multiple sampling points, thereby resolving problems such as poor sample representativeness, loss of volatile components, and cross-contamination.

[0021] The shape memory alloy valve is used to control the closing of a circular opening. Under normal conditions, the shape memory alloy valve seals the circular opening with a sealing plug. Under natural conditions, the shape memory alloy sheet causes the sealing plug to abut against the circular opening.

[0030] By rotating the bidirectional screw, the sampling cylinder can sample at different heights and also rotate to sample from different directions within the same level. Through multi-point sampling at the same level, the sampled items are more representative.

[0031] By controlling the sampling process with shape memory alloy valves and a negative pressure extraction system, the material does not come into contact with air throughout the entire sampling process, ensuring a completely closed sampling and reducing sample volatilization.

[0032] The telescopic sampling system enables rotational sampling to promote material flow, while the negative pressure extraction system can overcome the resistance of high-viscosity materials. The combination of the two reduces the difficulty of sampling high-viscosity materials. Attached Figure Description

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0044] Example 1

[0045] like Figure 1-8 As shown, this embodiment provides a retractable sampling device for flavor blending containers. It includes a retractable sampling system and a negative pressure extraction system, which are connected by a pipeline.

[0046] The telescopic sampling system includes a handle 1, with a bidirectional screw 2 fixedly connected to the lower end of the handle 1; the upper and lower threads of the bidirectional screw 2 have opposite directions of rotation, the outer wall of the middle section of the bidirectional screw 2 is smooth and without threads, and the upper section thread along its axis is connected to an upper nut 3, the middle section is rotatably connected to a middle nut 4, and the lower section thread is connected to a lower nut 5.

[0047] Rotating handle 1 causes the upper nut 3 and lower nut 5 to move away from or closer to the middle nut 4 because the upper and lower threads of the bidirectional screw 2 have opposite directions of rotation. A guide rod is also slidably connected to the outer ends of the upper nut 3 and lower nut 5 to restrict their rotation. When the bidirectional screw 2 rotates, the upper nut 3 and lower nut 5 only move in a straight line without rotating, and the middle nut 4 does not move up or down.

[0048] The upper nut 3, middle nut 4, and lower nut 5 are all fixedly connected to the outer ends of the sampling cylinder shell 6; the sampling cylinder shell 6 is a cylindrical structure, the axis of the sampling cylinder shell 6 is perpendicular to the bidirectional screw 2, and one end of the sampling cylinder shell 6 is provided with an opening; a sampling cylinder 7 is coaxially sleeved inside the sampling cylinder shell 6, and the sampling cylinder 7 is a cylindrical structure.

[0049] By rotating the handle 1, the extension and retraction of the bidirectional screw 2 are adjusted. The upper nut 3 and the lower nut 5 respectively drive the sampling cylinder outer shell 6 to move away from each other. The sampling cylinder 7 is fixedly connected to the sampling cylinder outer shell 6, thus allowing the position of the sampling cylinder 7 to be arbitrarily adjusted in the upper, middle, and lower layers to meet the sampling point requirements. Furthermore, during sampling, after adjusting the position of the sampling cylinder 7 to the required height, multi-directional sampling can be achieved within the same height by rotating the entire sampling device. During rotation, samples from different locations within the same layer can be obtained, resulting in samples with good representativeness. The sampling cylinder 7 is made of stainless steel with a mirror-polished inner wall, effectively preventing sample adhesion to the inner wall during sampling.

[0050] The sampling cylinder 7 is equipped with a pneumatic piston 8. A circular opening 9 is provided in the middle of one end of the sampling cylinder 7 near the opening of the outer shell 6. A shape memory alloy valve 10 is provided outside the circular opening 9. The shape memory alloy valve 10 is used to control the opening and closing of the sampling cylinder 7 to achieve closed sampling during the sampling process.

[0051] The shape memory alloy valve 10 includes a shape memory alloy sheet 11, which has a conical structure with the smaller diameter end positioned away from the circular opening 9. The larger diameter end of the shape memory alloy sheet 11 is fixedly connected to the sampling cylinder 7, and the diameter of the larger diameter end of the shape memory alloy sheet 11 is equal to the outer diameter of the sampling cylinder 7. Heating coils 13 are fixedly connected to the outer edges of both ends of the shape memory alloy sheet 11, and the heating coils 13 are electrically connected to the controller.

[0052] The shape memory alloy sheet 11 is made of shape memory alloy. After undergoing plastic deformation at low temperature, the shape memory alloy can automatically return to its original shape before deformation when heated to a certain critical temperature (phase transformation temperature). The phase transformation temperature of the shape memory alloy sheet 11 is higher than the operating temperature inside the flavor mixing tank to ensure that the shape memory alloy sheet 11 will not undergo phase transformation in the non-heated state, thereby ensuring that the sampling cylinder 7 is in a sealed state.

[0053] A sealing plug 12 is provided between the shape memory alloy sheet 11 and the circular opening 9, and the sealing plug 12 is fixedly connected to the shape memory alloy sheet 11. The sealing plug 12 has a cylindrical structure, and the diameter of the sealing plug 12 is greater than or equal to the diameter of the circular opening 9. The sealing plug 12 is made of a flexible material.

[0054] In its natural state, the shape memory alloy sheet 11 seals the circular opening 9 through the sealing plug 12. The shape memory alloy sheet 11 causes the sealing plug 12 to abut against the circular opening 9. After the controller heats the shape memory alloy sheet 11 through the electric heating coil 13, it causes a phase change in the shape memory alloy sheet 11. The phase change in the shape memory alloy sheet 11 will drive the sealing plug 12 to move away from the circular opening 9, causing the circular opening 9 to open. Multiple through holes are provided on the shape memory alloy sheet 11 along the axial direction of the sampling cylinder 7.

[0055] During sampling, the controller independently controls the heating coils 13 located at different positions, heating the coil 13 at the desired location individually to open the seal plug 12 and the circular opening 9. The sample enters the sampling cylinder 7 through multiple through holes on the shape memory alloy sheet 11. After sampling, the heating coils 13 stop heating, and the shape memory alloy sheet 11 cools naturally back to its initial state, quickly sealing the circular opening 9 to achieve airtight sampling. The three independent sampling cylinders 7 are controlled by independent shape memory alloy valves 10, which can avoid cross-contamination of samples during sampling.

[0056] When the telescopic sampling system is working, it requires the assistance of a negative pressure extraction system to keep the sampling cylinder 7 in a vacuum state.

[0057] The negative pressure extraction system includes a cavity 22 for holding gas; an upper piston plate 19 and a lower piston plate 21 are slidably connected inside the cavity 22, and a spring 20 is fixedly connected between the upper piston plate 19 and the lower piston plate 21; a cover 17 is fixedly connected to the top of the cavity 22; a large gear 16 is rotatably connected to the top of the cover 17; a small gear 15 is meshed with the outer end of the large gear 16; a motor 14 is fixedly connected to the cover 17 at a position corresponding to the small gear 15; and the small gear 15 is fixedly connected to the power shaft of the motor 14.

[0058] A screw 18 is fixedly connected to the top of the upper piston plate 19. The screw 18 passes through the cover 17 and the large gear 16 upwards, and the screw 18 is threadedly connected to the large gear 16.

[0059] A vertical tube 23 is fixedly connected to the lower end of the cavity 22. The vertical tube 23 is connected to the end of the sampling cylinder 7 away from the shape memory alloy valve 10 through a horizontal tube 24.

[0060] After adjusting the sampling cylinder 7 to the required position, the heating coil 13 is heated by the controller, the shape memory alloy valve 10 is opened, and the motor 14 is started simultaneously. The motor 14 drives the pinion 15 to rotate, and the pinion 15 meshes with the large gear 16, thereby driving the large gear 16 to rotate. The large gear 16 is threadedly connected to the screw 18, and the rotation of the large gear 16 drives the screw 18 to rise.

[0061] An anti-rotation groove is formed at the outer end of the screw 18 along its axial direction. An anti-rotation block, which mates with the anti-rotation groove, is provided on the cover 17. The cover 17 is slidably connected to the screw 18 via the anti-rotation block. When the screw 18 is subjected to torque under the drive of the large gear 16, the anti-rotation block embeds into the anti-rotation groove. The lateral reaction force of the groove wall on the anti-rotation block forms a rotational constraint, preventing the screw 18 from helically moving. As the large gear 16 rotates, the screw 18 can only move linearly along the anti-rotation groove and cannot rotate on its own.

[0062] Under normal conditions, the screw 18 rises, driving the upper piston plate 19, spring 20, and lower piston plate 21, which are fixedly connected at the lower end, to rise. At this time, the spring 20 is stretched by a length of A. During the rising process, the gas in the sampling cylinder 7 is drawn into the cavity 22 through the horizontal pipe 24 and the vertical pipe 23. The inner volume of the cavity 22 is more than three times the inner volume of the sampling cylinder 7 to completely contain all the gas in the sampling cylinder 7. There is a pneumatic piston 8 in the sampling cylinder 7. Initially, it is located at one end of the sampling cylinder 7 near the circular opening 9. When the negative pressure extraction system is working, it automatically moves from the end near the circular opening 9 to the end away from the circular opening 9 under the action of negative pressure. During this process, the gas in the sampling cylinder 7 enters the cavity 22, and the sampling cylinder 7 is in a negative pressure state. External samples enter the sampling cylinder 7. The samples do not come into contact with air throughout the process, reducing volatilization. Moreover, the presence of the pneumatic piston 8 can effectively prevent sample backflow from contaminating the negative pressure extraction system.

[0063] The device can rotate the sampling cylinder 7 during the sampling process, which can promote the flow of materials. The polished mirror surface of the inner wall of the sampling cylinder 7 can reduce the adhesion rate of materials. The negative pressure extraction can also overcome the resistance of some high-viscosity samples, making it easier to sample high-viscosity samples.

[0064] However, some high-viscosity samples can easily cause blockage of the sampling cylinder 7. A spring 20 is fixedly connected between the upper piston plate 19 and the lower piston plate 21 to detect whether the sampling cylinder 7 is blocked during evacuation. When the sampling cylinder 7 is blocked, the screw 18 is pulled, the upper piston plate 19 moves upward, and the pressure at the lower end of the lower piston plate 21 drops below the normal level due to the blockage of the sampling cylinder 7. This causes the distance between the upper piston plate 19 and the lower piston plate 21 to increase, and the spring 20 is stretched by a stretch length of B, where B>A. Therefore, when B is greater than A, it can be determined that the sampling cylinder 7 is blocked. The cavity 22 is marked with a scale. When the distance between the upper piston plate 19 and the lower piston plate 21 exceeds the threshold, it indicates that the sampling cylinder 7 is blocked and needs to be cleaned in time.

[0065] Both the vertical tube 23 and the horizontal tube 24 are EPDM flexible hoses, which can extend and retract to adapt to the position changes of the sampling cylinder 7 during the sampling process. Furthermore, the vertical tube 23 and the horizontal tube 24 are equipped with support rings, so that the tube walls are strong enough to resist the negative pressure generated by the negative pressure extraction system and not collapse.

[0066] This device utilizes a negative pressure extraction system in conjunction with a telescopic sampling system to achieve telescopic sampling from flavor blending containers. Three independent sampling cylinders 7 are arranged in layers, each controlled individually by a shape memory alloy valve 10, preventing cross-contamination. The rotation of the bidirectional screw 2 allows for simultaneous sampling at different levels within each cylinder 7, while also enabling rotational sampling from different locations within the same level, ensuring good representativeness of the samples. Controlled by the shape memory alloy valve 10 and the negative pressure extraction system, the material remains airtight throughout the sampling process, minimizing sample volatilization. Rotational sampling promotes material flow, and the negative pressure extraction system overcomes the resistance of high-viscosity materials; the combination of these two features makes sampling of high-viscosity materials easier.

[0067] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
