Description

Technical Field

[0001] The utility model relates to the technical field of odor detection, in particular to an aroma collection and enrichment device. Background Art

[0002] Most natural plant and animal materials contain volatile substances that can form special smells. Collecting volatile aroma substances in these materials, analyzing their chemical composition, and confirming the active aroma components are of great significance for guiding agricultural production, post-harvest storage, agricultural product processing, product quality control, and fragrance product development. At present, the analysis of volatile substances released by natural materials such as flowers, fruits, and leaves mostly uses solvent extraction, solid phase microextraction, and other methods for enrichment followed by gas phase or gas quality detection. These enrichment methods have a certain selectivity for the components and cannot truly reflect the true composition state of the volatile components. Therefore, it is very necessary to design a device that can more completely collect and enrich the chemical components in the gas. Utility Model Content

[0029] In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0030] Example 1

[0031] The invention aims to solve the problem of difficulty in quantitatively collecting volatile substances released by fresh flowers, fruits, leaves and other materials in the prior art. Figure 1 As shown, this embodiment proposes an aroma collection and enrichment device, including a soft bag 10, which has a sealable opening, and the soft bag 10 has a port for connecting to a pipeline 20; the pipeline 20, the first end of which is connected to the soft bag 10 through the port, and the second end of which is connected to the negative pressure suction device; a pipe valve 21, which is arranged on the pipeline 20 and is used to switch the open and closed state of the pipeline 20; a flow rate flow meter 23, which is arranged on the pipeline 20 and is used to detect the flow rate and flow rate of the gas in the pipeline 20; an adsorption device 24, whose main body is a closed container, the adsorption device 24 is arranged on the pipeline 20, and the adsorption device 24 has a replaceable adsorption material 26 inside. The soft bag 10, the pipeline 20 and other components in this embodiment are not adsorbent to the aroma components or the adsorption is within the threshold range to avoid the soft bag 10 and the pipeline 20 adsorbing the effective components, resulting in aroma collection errors, and the materials can be polypropylene, polyester, etc.

[0032] Specifically, the soft bag 10 in this embodiment is a bag body with certain tensile resistance, one side of the soft bag 10 has an opening, the inner wall of the opening is provided with a sealing strip 11, and the bag body of the soft bag 10 can be closed by the sealing strip 11, and one side of the soft bag 10 has a port, and the port is designed with a threaded port 12, and the function of the threaded port 12 is to achieve detachable docking with the pipeline 20. The function of the gas filling and discharging plug 13 on the bag body is to connect a special device, and a certain amount of gas is filled into the bag body of the soft bag 10 through the special device.

[0033] On the pipeline 20, a pipe valve 21, a solenoid valve 22, a flow rate flow meter 23 and an adsorption device 24 are arranged in sequence from the first end to the second end. After the pipeline 20 is connected to the soft bag 10 through the first end, the basic structure of the device can be formed.

[0034] When in use, first open the sealing strip 11 of the soft bag 10, put in a specified weight of fruit, such as 500g of apples, and then press the sealing strip 11. When preparing, first close the tube valve 21 and the solenoid valve 22 to make the inside of the soft bag 10 form a sealed state, and then connect the charging and discharging plug 13 through a special device to exhaust the air inside the soft bag 10 as much as possible, and then fill the soft bag with a specified amount of ambient gas through a special device, such as 200ml of air, and let the device stand for more than 24 hours. Then, connect the free port 25 at the second end of the pipeline 20 to the negative pressure extraction device. At the beginning, keep the tube valve 21 closed, and then open the solenoid valve 22. The negative pressure extraction device can exhaust the air inside the pipeline 20 as much as possible, and then close the solenoid valve 22. When the aroma collection and enrichment device is used, the pipe valve 21 is opened, and then the electromagnetic valve 22 is gradually opened. In this process, the flow velocity of the air in the pipeline 20 is detected by the flow velocity meter 23. If the air flow velocity is too fast, it is difficult for the adsorption material 26 in the adsorption device 24 to completely adsorb the organic matter released by the fruit. The flow velocity meter 23 and the electromagnetic valve 22 are controlled by the controller in linkage until the flow velocity meter 23 detects that the flow velocity of the air in the pipeline 20 reaches a predetermined flow velocity, and then the electromagnetic valve 22 maintains the opening.

[0035] The negative pressure extraction device continuously provides negative pressure, and the gas in the soft bag 10 gradually passes through the adsorption device 24. After the aroma collection is completed, the tube valve 21 is closed, and the adsorption material 26 in the adsorption device 24 is taken out and sent to the laboratory for aroma detection.

[0036] In this embodiment, the adsorption device 24 includes a first tube body 241 and a second tube body 242. The first tube body 241 and the second tube body 242 can be assembled with each other through a threaded connection. The first tube body 241 and the second tube body 242 can be assembled to form a container for accommodating the adsorption material 26. The front end and the rear end of the container are respectively connected to the pipeline 20 and the free port 26 through a hose. The first tube body 241 and the second tube body 242 can be disassembled to take out the adsorption material 26, or the adsorption material 26 can be filled into the adsorption device 24.

[0037] The adsorbent material 26 is mixed in a certain proportion and pressed into a sheet or column with a diameter of 4-8mm and a thickness of 2-5mm. The adsorbent material 26 is one or more of C18, activated carbon, polydimethylsiloxane, divinylbenzene, and magnesium sulfate adsorbent materials. Among them, C18 can be a simple octadecyl bonded silica gel, or a modified C18 bonded with amino, polyethylene glycol, etc. The material itself has good thermal stability below 80°C, and can indiscriminately adsorb most volatile aldehydes, alcohols, ketones, esters, alkanes, terpenes, furans, pyrans, pyrazines, etc. at room temperature or low temperature. Heating the adsorbent material 26 to 40°C or above, or eluting with an organic solvent can better desorb the aroma components. Excluding mechanical and other external force damage, the adsorbent material 26 can be reused more than one hundred times.

[0038] The gas collection bag of the utility model can be disassembled and replaced, making collection more convenient. The soft bag 10 is reserved with a gas filling and discharging plug 13 for gas in and out. The gas filling and discharging plug 13 has good air tightness and does not leak under normal circumstances. The filling and discharging requires a specific interface to open. The aroma collection and enrichment device is equipped with a power system and a gas flow measurement system, which can achieve accurate quantification of the aroma volume by setting the gas flow rate and working time. This device has the characteristics of simple structure, low cost, and easy use. The collector can collect and enrich anytime and anywhere, and the application prospect is very promising.

[0039] Example 2

[0040] like Figure 4 As shown, the aroma collection and enrichment device in this embodiment is similar to the aroma collection and enrichment device in Example 1, and the difference lies in the structure of the adsorption device 24. In this embodiment, the adsorption device 24 can be connected to the pipeline using a tube body, and a detachable sealing end cap is installed at the upper end and / or the lower end. The sealing form can be a rubber ring seal or a thread seal. The use method and effect of the aroma collection and enrichment device in this embodiment are similar to those of the aroma collection and enrichment device in Example 1, and will not be repeated.

[0041] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
