Description

Technical Field

[0001] This utility model belongs to the field of liquor dilution technology, specifically relating to a sample dilution device for extracting flavor substances from liquor. Background Technology

[0002] Currently, more than 3,000 flavor components have been detected in baijiu, mainly including esters, acids, alcohols and other main flavor compounds, as well as health-functional compounds such as pyrazines, phenols, terpenes and aldehydes, aromatic compounds, etc. The combination of various flavor components forms the unique aroma of baijiu, and the extraction of flavor components is the main method of baijiu detection.

[0003] In the current process of diluting samples after extracting flavor substances from baijiu, the sample is usually added to a fixed container and the diluent is gradually added until the alcohol concentration of the sample and diluent reaches the standard. This dilution operation is carried out in multiple intermittent steps, and the subsequent sample dilution operation can only be performed after the diluted liquid is drained. This is not only inefficient, but each dilution operation will also introduce a certain error and have poor accuracy.

[0004] Therefore, a sample dilution device for extracting flavor substances from baijiu (Chinese liquor) is proposed. Summary of the Invention

[0005] This invention provides a sample dilution device for extracting flavor substances from baijiu (Chinese liquor), which aims to solve the problems mentioned above.

[0006] This utility model provides a sample dilution device for extracting flavor substances from baijiu (Chinese liquor), including a dilution cylinder; a direct current tube at the bottom of the dilution cylinder; a cylinder cap at the top of the dilution cylinder; an alcohol concentration detector, a main sample outlet tube, and a shut-off valve on the outer wall of the direct current tube, the main sample outlet tube being located between the alcohol concentration detector and the shut-off valve, and below the alcohol concentration detector; a support frame located at the bottom of the inner wall of the dilution cylinder; a first forward spiral blade placed inside the dilution cylinder; a second reverse spiral blade located on the upper end of the first forward spiral blade; a third forward spiral blade located on the upper end of the second reverse spiral blade; two metering pumps symmetrically arranged on the top of the cylinder cap; and sample inlet pipes and diluent inlet pipes respectively located at the input ends of the two metering pumps.

[0007] Furthermore, a base is provided at the lower position of the dilution cylinder, and four support legs are symmetrically arranged on the top of the base. A temporary storage box is provided at the top of the four support legs. A replenishment pipe is provided at the top of the temporary storage box, and the temporary storage box and the DC pipe are connected and fixedly connected. An auxiliary sample outlet pipe is provided at the bottom of the temporary storage box.

[0008] Furthermore, the DC tube and the cap are both connected and fixed to the dilution cylinder via flanges;

[0009] By adopting the above technical solution and fixing it with flange connection, it is easy to disassemble and assemble the DC pipe and the cylinder cover with the dilution cylinder, thereby facilitating inspection and maintenance.

[0010] Furthermore, the detection end of the alcohol concentration detector penetrates the outer wall of the DC tube and is located at its inner center.

[0011] By adopting the above technical solution, the alcohol concentration in the diluted sample can be detected by contacting the detection end of the alcohol concentration detector with the sample flowing inside the DC tube after dilution, and the dilution status of the sample can be detected in real time.

[0012] Furthermore, the connection points of the first and second positive spiral blades with the anti-spiral spiral blade form a 90-degree angle;

[0013] By adopting the above technical solution, the flow direction and state of the fluid can be disrupted through vertical connection. Through the "segmentation-displacement-overlapping" mechanism, uniform mixing can be completed under the spiral flow of the fluid, and continuous mixing operation can be achieved.

[0014] Furthermore, the outer walls of the first positive spiral blade, the second negative spiral blade, and the third positive spiral blade are attached to the inner wall of the dilution cylinder.

[0015] By adopting the above technical solution, the liquid is ensured to flow along the first forward spiral blade, the second reverse spiral blade, and the third forward spiral blade.

[0016] Furthermore, a butterfly valve is provided at the bottom end of the auxiliary sample tube;

[0017] By adopting the above technical solution, the opening and closing of the auxiliary sample tube can be controlled by the butterfly valve, thereby controlling the outflow of the diluted sample in the temporary storage box.

[0018] The beneficial effects of this utility model are as follows:

[0019] This invention utilizes a static mixer composed of a first spiral blade, a second spiral blade, and a third spiral blade. This mixer can disrupt the flow direction and state of the liquid. Through a "segmentation-displacement-overlapping" mechanism, the liquid is uniformly mixed under spiral flow, enabling continuous dilution operations. It can also monitor the alcohol concentration in the diluent in real time. Once the target concentration is reached, the amount of sample and diluent added is continuously maintained. By using a direct current tube for diversion, the dilution operation can be kept continuous, making the dilution operation convenient, efficient, and highly accurate.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example 1

[0029] Reference Figure 1-3This utility model provides a sample dilution device for extracting flavor substances from baijiu (Chinese liquor). The device includes a dilution cylinder 1, a direct current pipe 2 at the bottom, and a cylinder cover 3 at the top. Both the direct current pipe 2 and the cylinder cover 3 are connected to the dilution cylinder 1 via flanges, facilitating easy assembly and disassembly for maintenance. An alcohol concentration detector 4, a main sample outlet pipe 5, and a shut-off valve 6 are sequentially arranged on the outer wall of the direct current pipe 2 from top to bottom. The detection end of the alcohol concentration detector 4 penetrates the outer wall of the direct current pipe 2 and is located in its center. By contacting the diluted sample flowing inside the direct current pipe 2, the detection end of the alcohol concentration detector 4 can detect the alcohol concentration in the diluted sample, allowing real-time monitoring of the sample's dilution status. A support frame 7 is located near the bottom of the inner wall of the dilution cylinder 1. The support frame 7 supports the first positive spiral blade 8, the second negative spiral blade 9, and the third positive spiral blade 10, and also facilitates the operation of the first positive spiral blade 8. After the reverse-rotating helical blade 9 and the forward-rotating helical blade 10 are removed and cleaned, a forward-rotating helical blade 8 is placed inside the dilution cylinder 1 near the support 7. A reverse-rotating helical blade 9 is located on the upper end of the forward-rotating helical blade 8, and a forward-rotating helical blade 10 is located on the upper end of the reverse-rotating helical blade 9. The connection points of the forward-rotating helical blades 8 and 10 with the reverse-rotating helical blade 9 form a 90-degree angle. This vertical connection can disrupt the flow direction and state of the liquid. This is achieved through a "splitting-displacement-overlapping" mechanism. The liquid is uniformly mixed under spiral flow, which can realize continuous mixing operation, and thus fully mix the liquor sample and the diluent. The outer walls of the first spiral blade 8, the second spiral blade 9, and the third spiral blade 10 are attached to the inner wall of the dilution cylinder 1 to ensure that the liquid flows along the first spiral blade 8, the second spiral blade 9, and the third spiral blade 10. Two metering pumps 18 are symmetrically arranged on the top of the cylinder cover 3. The input ends of the two metering pumps 18 are respectively provided with sample inlet pipe 11 and diluent inlet pipe 12.

[0030] Specifically, when diluting the baijiu flavor substance sample, the sample is quantitatively added to the dilution cylinder 1 through the metering pump 18 at the bottom of the sample inlet pipe 11, and the diluent is gradually added to the dilution cylinder 1 through the metering pump 18 at the bottom of the dilution inlet pipe 12. The two liquids enter the dilution cylinder 1 simultaneously, and the two liquids flow downwards in a spiral motion along the first spiral blade 10, the second spiral blade 9, and the first spiral blade 8. The static mixer composed of the first spiral blade 8, the second spiral blade 9, and the second spiral blade 10 can disrupt the flow direction and state of the liquid. Through the "segmentation-displacement-overlapping" mechanism, the liquid is uniformly mixed under the spiral flow, which can realize continuous mixing operation, thereby fully mixing the baijiu sample and the diluent. The diluted and mixed liquid flows into the direct current pipe 2.

[0031] The detection end of the alcohol concentration detector 4 detects the alcohol concentration of the liquid in the DC tube 2 in real time. As the diluent is gradually added, the alcohol concentration of the diluted liquid gradually decreases. When the detected alcohol concentration value reaches the set value, the quantitative addition of diluent is maintained. After a period of time, the control shut-off valve 6 is closed. At this time, the bottom end of the DC tube 2 is blocked, and the diluted liquid is discharged through the main sample outlet tube 5, thus achieving accurate sample dilution.

[0032] Example 2

[0033] Reference Figure 1 Based on the above embodiments, this utility model embodiment also proposes a sample dilution device for extracting flavor substances from baijiu (Chinese liquor), including a DC tube 2, a temporary storage box 15 at the bottom of the DC tube 2, an alcohol concentration detector 4 on one side wall of the temporary storage box 15, and a liquid level sensor on the inner side wall of the temporary storage box 15. The detection end of the alcohol concentration detector 4 is located inside the temporary storage box 15. Four support legs 14 are symmetrically arranged at the bottom of the temporary storage box 15, and a base 13 is provided at the bottom end of the four support legs 14. A replenishment tube 16 is provided at the top of the temporary storage box 15, and an auxiliary sample outlet tube 17 is provided at the bottom of the temporary storage box 15. A butterfly valve is provided at the bottom end of the auxiliary sample outlet tube 17. The butterfly valve can control the opening and closing of the auxiliary sample outlet tube 17, thereby controlling the outflow of the diluted sample in the temporary storage box 15.

[0034] Specifically, the substandard mixed liquid enters the temporary storage tank 15 with the shut-off valve 6 open. The alcohol concentration detector 4 detects the alcohol concentration in the temporary storage tank 15, and the liquid level sensor detects the liquid level in the temporary storage tank 15. The liquid volume is calculated based on the volume of the temporary storage tank 15, and an appropriate amount of diluent is added according to the alcohol concentration value to achieve the required level. Finally, the liquid is discharged through the auxiliary sample tube 17. The diluted liquid tested before the standard was met can be utilized, avoiding waste.
