Description

Technical Field

[0001] This utility model belongs to the field of fermented grain analysis technology, and in particular relates to a mixing and pulverizing device for analyzing fermented grain flavor samples. Background Technology

[0002] As a key intermediate in the brewing of Maotai-flavor liquor, the accurate detection of its flavor compounds (such as esters, alcohols, and pyrazines) is crucial for process optimization and quality control. Currently, organic solvent extraction is commonly used for its detection. However, the pretreatment requires pulverizing the viscous mash sample with a moisture content of 50% into a homogeneous state. The pulverizing equipment used is for pulverizing individual samples before extracting flavor substances, which is cumbersome, has a high risk factor, and has significant drawbacks. When processing viscous materials containing moisture, frequent washing of the equipment can easily lead to short circuits and electric shocks, posing safety hazards. In traditional pulverizers, it is difficult to thoroughly clean the chamber residue, causing cross-contamination of samples and increasing the error of sample test results. Moreover, a single processing volume of more than 50g is required to ensure the pulverization effect, and repeated disassembly and cleaning of parts is necessary, resulting in low processing efficiency. At the same time, the mash is prone to producing colloidal agglomerates during the pulverization process, leading to the adsorption and loss of flavor substances. Utility Model Content

[0003] The purpose of this invention is to overcome the defects of the prior art and provide a mixing and pulverizing device for analyzing the flavor of fermented mash. The blade structure is separate from the drive base but can be engaged with it. That is, after pulverization, the blade structure can be completely separated from the drive base, improving safety during frequent water washing. At the same time, after pulverization, it can be directly cleaned by running a second cycle with cleaning solution, reducing the cross-contamination rate. During the pulverization process, the rotating vortex drives the sample to mix evenly, and the solvent can simultaneously extract the flavor from the sample, improving processing efficiency and avoiding the formation of colloidal agglomerates in the fermented mash during pulverization, which would lead to the adsorption and loss of flavor substances.

[0004] The objective of this utility model is achieved through the following technical solution: A mixing and pulverizing device for analyzing the flavor of fermented mash includes a drive base and a centrifuge tube mounted on the drive base. A crushing component is integrally provided at the bottom of the centrifuge tube. The crushing component includes a housing connected to the centrifuge tube and a slot disposed in the housing. One end of the slot is connected to a blade structure located outside the housing, and the other end of the slot is engaged with the output end of the drive base. In this embodiment, the blade structure and the drive base are separate yet interlocked. After crushing, the blade structure can be completely separated from the drive base, improving safety during frequent water washing. Furthermore, after crushing, the tube can be cleaned directly with the cleaning solution during a second run, reducing cross-contamination. During crushing, the rotating vortex mixes the sample, and the solvent simultaneously extracts the flavor from the sample, improving processing efficiency and preventing the formation of gelatinous agglomerates during crushing that would lead to flavor loss.

[0005] In one embodiment, the slot and the output end of the drive base mesh with each other to form a complete cylindrical structure.

[0006] In one embodiment, the crushing assembly further includes a blade shaft, one end of which is connected to the slot and the other end of which is connected to the blade structure. A sealing ring is also fitted on the blade shaft between the blade shaft and the housing. In this embodiment, the output end of the drive base drives the slot to rotate, and at the same time, the blade shaft drives the blade structure connected to the slot to crush the mash. The sealing ring is set to seal the crushing component to prevent the solution in the centrifuge tube from leaking out.

[0007] In one embodiment, the centrifuge tube has capacity graduation lines on its side wall.

[0008] In one embodiment, a cap is also installed on the top of the centrifuge tube.

[0009] In one embodiment, the centrifuge tube opening also has a toothed structure.

[0010] In one embodiment, the drive base includes a control console and a speed-regulating motor disposed within the control console, the output end of the speed-regulating motor extending in a vertical direction.

[0011] In one embodiment, the speed range of the variable speed motor is 0-10000 RPM.

[0012] The beneficial effects of this utility model are as follows: This invention provides a mixing and pulverizing device for analyzing the flavor of fermented grains. The device simultaneously pulverizes the fermented grains and extracts flavor substances within a centrifuge tube. The blade structure is separate from the drive base but can also be engaged. After pulverization, the blade structure can be completely separated from the drive base, improving safety during frequent water washing. Furthermore, after pulverization, the device can be directly cleaned with a cleaning solution for a second run, reducing cross-contamination. During pulverization, the rotating vortex mixes the sample, and the solvent simultaneously extracts the flavor from the sample, improving processing efficiency and preventing the formation of gelatinous agglomerates during pulverization, which would otherwise lead to the loss of flavor substances.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] This invention provides a mixing and pulverizing device for analyzing the flavor samples of fermented grains, such as... Figure 1 , Figure 2 as well as Figure 4 As shown, it includes a drive base 2 and a centrifuge tube 1 mounted on the drive base 2. A crushing component is integrally provided at the bottom of the centrifuge tube 1. The crushing component includes a housing 3 connected to the centrifuge tube 1 and a slot 4 disposed in the housing 3. One end of the slot 4 is connected to a blade structure 5, which is located outside the housing 3. The other end of the slot 4 is engaged with the output end of the drive base 2. It should be noted that in this embodiment, the mash sample is placed into centrifuge tube 1, and an appropriate amount of pure water and organic solvent are injected. The integrated crushing component at the bottom of centrifuge tube 1 is then snapped onto the drive base 2. This means that the mash is crushed and flavor substances are extracted simultaneously within centrifuge tube 1. The blade structure 5 is separate from the drive base 2 but can also be snapped onto it. After crushing, the blade structure 5 can be completely separated from the drive base 2, improving safety during frequent water washing. After crushing and extraction, the tube can be cleaned by directly running the cleaning solution again, reducing cross-contamination. During the crushing process, the rotating vortex mixes the sample, and the solvent can simultaneously extract the flavor from the sample, improving processing efficiency and preventing the formation of gelatinous agglomerates during crushing, which would lead to the loss of flavor substances. Specifically, such as Figure 4 As shown, the card slot 4 and the output end of the drive base 2 mesh with each other to form a complete cylindrical structure, which facilitates quick connection or separation between the card slot 4 and the output end of the drive base 2. In one embodiment, such as Figure 2 and Figure 3 As shown, the crushing assembly also includes a blade shaft 6. One end of the blade shaft 6 is connected to the slot 4, and the other end is connected to the blade structure 5. A sealing ring 7 is also fitted on the blade shaft 6 between the blade shaft 6 and the housing 3. That is, the output end of the drive base 2 drives the slot 4 to rotate, and at the same time, the blade shaft 6 drives the blade structure 5 connected to the slot 4 to crush the mash. The sealing ring 7 seals the crushing assembly to prevent the solution in the centrifuge tube 1 from leaking out. In one embodiment, such as Figure 1 and Figure 2 As shown, the centrifuge tube 1 has a volume scale line 8 on its side wall, which facilitates the quantitative addition of pure water and organic solvents for extracting flavor substances. In one embodiment, such as Figure 1 As shown, a cap 9 is installed on the top of the centrifuge tube 1, and the opening of the centrifuge tube 1 also has a grooved structure. That is, the cap 9 is used to seal the centrifuge tube 1, and the grooved structure at the opening prevents the solution from splashing out, thus ensuring the detection effect. In one embodiment, such as Figure 1 As shown, the drive base 2 includes a control console and a speed-regulating motor installed in the control console. The output end of the speed-regulating motor extends vertically, and the speed range of the speed-regulating motor is 0-10000 RPM. It should be noted that in this embodiment, the amount of mash processed at one time does not need to reach 50g to ensure the pulverization effect. For example, 10g of mash sample can be weighed and placed into centrifuge tube 1, then 10ml of pure water and 20ml of extraction organic solvent can be injected. After tightening the cap 9 on centrifuge tube 1, the slot 4 at the bottom of centrifuge tube 1 is connected to the output end of the drive base 2. The pulverization at 5000RPM is started for 3 minutes. A vortex field is formed in centrifuge tube 1 to achieve three-dimensional shearing. At the same time, the extraction of flavor substances is also achieved during the pulverization process.
