Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of edible essence detection, and concretely relates to a gas dilution device for edible essence detection. BACKGROUND

[0002] Edible essence detection is an important link in food safety and quality control. It is to ensure that edible essence does not contain harmful substances such as heavy metals, pesticide residues, microorganisms, etc., to verify whether the edible essence meets relevant laws, regulations and standards, to ensure that the composition and concentration of the essence meet the label instructions, and to maintain the consistency and stability of the product.

[0003] Edible essence detection usually includes the following aspects: gas chromatography (GC): commonly used for analyzing volatile components, especially the main components of spices. High-performance liquid chromatography (HPLC): used for separating and quantifying non-volatile or thermally unstable components. Mass spectrometry (MS): combined with GC or HPLC, can help identify and quantify components in complex mixtures. Olfactory test: sensory evaluation of fragrance by professional reviewers or consumer panels. Bacterial culture: detects bacteria, yeast and mold and other microorganisms that may be present in the essence. pH, specific gravity, refractive index, etc.: These indicators help evaluate the physical properties and quality of the essence.

[0004] During the edible essence detection process, direct sampling can easily cause the detector to saturate due to the high concentration of essence, affecting the accuracy of the detection results. UTILITY MODEL CONTENT

[0005] Therefore, the utility model provides a gas dilution device for edible essence detection, which can solve the problem of detector saturation and affect the accuracy of detection results due to high concentration of essence during the edible essence detection process.

[0006] The utility model is implemented as follows:

[0007] The utility model provides a gas dilution device for edible essence detection, which comprises a dilution cavity, a sampling assembly, a dilution gas circuit, a mixing cavity and a detection gas circuit. The dilution cavity is used to contain the edible essence sample to be diluted and dilution gas. The sampling assembly is arranged at the top of the dilution cavity. The dilution gas circuit is connected with the side wall of the dilution cavity. The sampling assembly and the dilution gas circuit are used to add samples to the inside of the dilution cavity. The mixing cavity is arranged below the dilution cavity and connected with the dilution cavity through a pipeline, which is used to fully mix the diluted sample with the dilution gas. One end of the detection gas circuit is connected with the mixing cavity, and the other end is connected with a detection instrument, which is used to deliver the mixed and diluted sample to the detection instrument.

[0008] On the basis of the above technical scheme, the gas dilution device for edible essence detection can be further improved as follows:

[0009] The dilution cavity is internally provided with a spoiler fixedly connected with the inner wall of the dilution cavity, which is used for enhancing the mixing effect of the dilution gas and the edible essence sample to improve the dilution uniformity.

[0010] Further, the spoiler is spirally arranged.

[0011] Further, the mixing cavity is internally filled with inert glass beads with a diameter of 2-5 mm, which is used for increasing the gas contact area to improve the mixing uniformity of the sample and the dilution gas.

[0012] Further, the sample inlet assembly comprises a sample inlet, a sample valve and a sample tube, the sample inlet is arranged at one side of the dilution cavity, the sample valve is connected with the sample inlet, the sample inlet is used for guiding the edible essence sample into the dilution cavity, and the sample valve is used for controlling the entering of the sample.

[0013] Further, the bottom of the sample tube is provided with an asbestos net, and the bottom is provided with a heater, which is used for heating the bottom of the sample tube.

[0014] Further, the inside of the sample tube is placed with a paste edible essence.

[0015] Further, the top of the sample tube is provided with a sealing plug, which is used for making the single gas passage formed by the sample tube and the sample inlet to be directed to the inside of the dilution cavity when the paste edible essence inside the sample tube is combusted and volatilized.

[0016] Further, the dilution gas circuit is in through connection with a dilution gas tank.

[0017] Further, the dilution cavity is in a cylindrical shape and is made of stainless steel.

[0018] Compared with the prior art, the gas dilution device for edible essence detection provided by the utility model has the beneficial effects that:

[0019] The dilution cavity is responsible for containing the flavor sample to be diluted and the dilution gas. It is the core part of the device and directly affects the dilution efficiency and uniformity. By containing the sample and dilution gas, the dilution cavity provides a mixing space to ensure that the gas can fully contact the flavor sample and complete the dilution process. Its material usually has corrosion resistance, high temperature resistance and good sealing performance, which can ensure that the sample in the detection process is not contaminated by the outside world. The dilution cavity is cylindrical, which helps to achieve uniform airflow distribution. The use of stainless steel ensures the durability and stability of the device in different environments.

[0020] The main function of the sample injection assembly is to control the injection of the flavor sample. Its accuracy and reliability are directly related to the injection accuracy of the sample. This assembly controls the sample inlet and injection valve to ensure that the flavor sample can enter the dilution cavity in the right amount and at the right time. The sample inlet is located at the top of the dilution cavity to prevent backflow of the sample during injection. The sample inlet is responsible for receiving the flavor sample. The injection valve is used to accurately control the flow of the flavor sample, preventing too much or too little sample from entering the cavity. The sample tube transports the flavor sample from the outside to the dilution cavity, and the sample is transported through the pipeline. The connection of the injection valve and the sample inlet can adjust the input amount of the sample, and by opening and closing the valve, the rate of sample injection can be adjusted. The dilution gas path is connected to the dilution gas tank to guide the dilution gas into the dilution cavity. The dilution gas plays a role in diluting the flavor sample to the required concentration in this link. After passing through the designed gas path, the dilution gas can uniformly mix with the flavor sample, ensuring the accuracy of the flavor concentration during detection. The design of the dilution gas path needs to ensure the smoothness of the gas flow, avoiding gas short circuit or turbulence.

[0021] The mixing cavity is responsible for fully mixing the diluted flavor sample with the dilution gas to ensure uniform sample dilution. The mixing cavity is located below the dilution cavity and is connected to it through a pipeline to mix the gas and flavor sample in the dilution cavity. The uniformity of this process is crucial to the final detection result. The mixing cavity is filled with inert glass beads, which can effectively increase the contact area of the gas, promote the full contact of the gas with the flavor sample, and thus improve the mixing effect. This helps to increase the contact time and intensity of the dilution gas with the flavor sample, ensuring the uniformity of the mixing. The diameter of the glass beads is 2-5 mm, which is neither easy to block the channel nor can effectively promote gas mixing under appropriate airflow conditions.

[0022] The detection gas path transports the uniformly mixed gas in the mixing cavity to the detection instrument for flavor component detection. The detection gas path needs to ensure stable gas flow and match the requirements of the detection instrument to ensure the accuracy of the final detection. One end of the detection gas path is connected to the mixing cavity, and the other end is connected to the detection instrument to ensure that the detection sample can be smoothly sent to the detection equipment for analysis.

[0023] The design of the detection gas path needs to avoid the leakage of gas flow to maintain the integrity and concentration of the sample.

[0024] The spoiler is installed inside the dilution cavity and fixedly connected with the inner wall of the dilution cavity, which enhances the mixing effect of the dilution gas and the flavor sample. Through the spoiler, the gas flow is disturbed, and a more uniform turbulent flow can be formed inside the cavity, thereby improving the contact efficiency of the gas and the sample and increasing the dilution uniformity.

[0025] Spiral design: the spiral spoiler design can increase the rotation and mixing intensity of the gas flow, making the contact of the gas and the sample more thorough, which helps to improve the dilution effect.

[0026] The sample tube is used to transport the flavor sample to the sample inlet. The inside can place the paste flavor, which ensures that the flavor can smoothly enter the dilution cavity during heating and volatilization. The asbestos net at the bottom helps to uniformly distribute the flavor sample, avoiding blockage or uneven volatilization of the flavor when heated due to uneven heating. The heater is used to heat the bottom of the sample tube to facilitate the volatilization of the paste flavor and fully contact with the dilution gas. The sealing plug ensures that the flavor inside the sample tube remains closed until it enters the dilution cavity through the single gas channel, thereby ensuring that the volatilization path of the flavor is controlled.
