Description

Technical Field

[0001] This invention relates to the field of industrial fragrance technology, and in particular to a device and method for detecting fragrance loss during industrial fragrance addition. Background Technology

[0002] In the food, daily chemical, and tobacco processing industries, flavoring is a crucial step in the production process. Its purpose is to add flavorings during product manufacturing to enhance aroma and taste, significantly improving product quality. Flavoring is typically carried out in a sealed flavoring machine by spraying flavorings. During the flavoring process, some flavorings are emitted from the machine's outlet with the gas, resulting in some loss. When the amount of flavoring added is fixed, determining the effective utilization rate of the flavoring requires determining the amount of flavoring lost during the flavoring process.

[0003] Therefore, there is an urgent need to design a detection scheme that can determine the amount of fragrance loss during the fragrance addition process. Summary of the Invention

[0004] The purpose of this invention is to provide a device and method for detecting fragrance loss during industrial fragrance addition, so as to solve the problems existing in the prior art and to determine the amount of fragrance loss during the fragrance addition process.

[0005] To achieve the above objectives, the present invention provides the following solution:

[0007] The air inlet pipe is connected at one end to the air outlet of the aromatherapy machine, and at the other end to a flow meter, a first ethanol gas sensor, a second ethanol gas sensor and a carbon dioxide gas sensor in series.

[0008] The temperature control module is connected to the air inlet pipe located between the first ethanol gas sensor and the second ethanol gas sensor, and can heat the gas in the air inlet pipe until the flavoring components are completely burned.

[0009] The data monitoring panel is connected to the first ethanol gas sensor, the second ethanol gas sensor, and the carbon dioxide gas sensor respectively, and is used to read and display the data from the first ethanol gas sensor, the second ethanol gas sensor, and the carbon dioxide gas sensor.

[0010] Preferably, it also includes an air pump, which is located on the air inlet pipe and is capable of drawing gas from the fragrance dispenser into the air inlet pipe.

The heating device is disposed on the inlet pipe between the first ethanol gas sensor and the second ethanol gas sensor, and the temperature control box is connected to the heating device through wires and thermocouples.

[0012] Preferably, the heating device includes a spring heating coil, which is sleeved on the air inlet pipe between the first ethanol gas sensor and the second ethanol gas sensor.

[0013] Preferably, the temperature control module further includes a heat sink, which is located on the air inlet pipe between the heating device and the second ethanol gas sensor, and can dissipate the heated gas to room temperature; the specific structure of the heat sink is not limited, and it can adopt air cooling, liquid cooling or other structures.

[0014] Preferably, the end of the air inlet pipe away from the fragrance dispenser is connected to a gas outlet pipe, and the end of the gas outlet pipe is connected to an exhaust gas treatment device.

[0016] Preferably, the first ethanol gas sensor, the second ethanol gas sensor, and the carbon dioxide gas sensor are all connected to the server in the data monitoring panel via data cables.

[0017] This invention also provides a method for detecting fragrance loss during industrial fragrance addition, comprising the following steps:

[0018] Step 1: Connect the power supply to the temperature control box to control the heating device to enter the heating stage. After reaching the required temperature, maintain a constant temperature.

[0019] Step 2: Start the air pump and observe the flow meter reading until the reading is within the set range. Then, turn on the power to the first ethanol gas sensor, the second ethanol gas sensor, and the carbon dioxide gas sensor, and wait for the data monitoring panel reading to stabilize.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The purpose of this invention is to provide a device and method for detecting fragrance loss during industrial fragrance addition, so as to solve the problems existing in the prior art and to determine the amount of fragrance loss during the fragrance addition process.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] In industrial production processes, such as the addition of fragrances to cosmetics, toothpaste, and food, fragrance addition processes are involved. Due to numerous influencing factors, it is difficult to accurately obtain the fragrance absorption rate. While fragrances are diverse and their specific components vary, their basic components all include organic compounds such as ethanol. By detecting the ethanol content of the fragrance before heat treatment and comparing it with the ethanol and carbon dioxide content in the gas after heat treatment, the amount of fragrance loss can be calculated. Based on this, this invention designs a quantitative evaluation method for fragrance loss in the fragrance addition process, providing technical and data support for the effectiveness of the fragrance addition process. (See attached figure.) Figure 1 As shown, the fragrance loss detection device in the industrial fragrance addition process of the present invention includes an air inlet pipe 1, one end of which is connected to the air outlet of the fragrance adding machine, and the other end is connected in series with a flow meter 3, a first ethanol gas sensor 4, a second ethanol gas sensor 8, and a carbon dioxide gas sensor 9. An air pump 2 is provided on the air inlet pipe 1. In this embodiment, the air pump 2 is a precision air pump, which can draw the gas in the fragrance adding machine into the air inlet pipe 1. The fragrance adding machine is a mature and known structure, so it will not be described in detail. The fragrance adding process is achieved by spraying fragrance into the fragrance adding machine. During the fragrance adding process, the fragrance that is not adsorbed onto the product is discharged with the gas through the air outlet of the fragrance adding machine and is drawn into the air inlet pipe 1 by the air pump 2. The temperature control module is connected to the air inlet pipe 1 located between the first ethanol gas sensor 4 and the second ethanol gas sensor 8, and can heat the gas in the air inlet pipe 1 until the fragrance components are completely burned. The data monitoring panel 11 is connected to the first ethanol gas sensor 4, the second ethanol gas sensor 8, and the carbon dioxide gas sensor 9 respectively, and is used to read and display the data of the first ethanol gas sensor 4, the second ethanol gas sensor 8, and the carbon dioxide gas sensor 9.

[0033] In order to ensure that the fragrance in the gas to be tested in the inlet pipe 1 is completely burned, the temperature control module in this embodiment includes a heating device 5 and a temperature control box 6. The heating device 5 is set on the inlet pipe 1 between the first ethanol gas sensor 4 and the second ethanol gas sensor 8. The temperature control box 6 is connected to the heating device 5 through wires and thermocouples.

[0034] In one embodiment, a heating section pipeline is also provided. The inlet pipeline 1 is connected to the flow meter 3. The outlet of the flow meter 3 is connected to the first ethanol gas sensor 4. The first ethanol gas sensor 4 is divided into two parts: a display and a detection probe, which are connected by a data cable. One end of the detection probe is connected to the outlet of the flow meter 3, and the other end of the detection probe is connected to the heating section pipeline through a quick connector. The heating device 5 adopts a spring heating coil, which is sleeved on the heating section pipeline. To avoid errors between the second ethanol gas sensor 8 and the carbon dioxide gas sensor 9 due to temperature differences, a radiator 7 is installed at the end of the heating section pipe. The radiator 7 is located between the heating device 5 and the second ethanol gas sensor 8. After the gas flowing through the heating section pipe reaches the required reaction temperature and undergoes a complete reaction, it enters the radiator 7 through a gas pipe for further cooling, reducing the temperature of the treated gas to room temperature. The radiator 7 employs a known air-cooled structure and is equipped with a cooling fan to cool the gas pipe passing through it and the gas within the pipe. In other embodiments, liquid cooling can also be used. A heat exchange tube is installed inside the radiator 7, and a coolant is circulated within the tube as a heat exchange medium to exchange heat with the gas pipe passing through it, thereby reducing the gas within the pipe to room temperature. The second ethanol gas sensor 8 and the carbon dioxide gas sensor 9 are connected in series to the outlet of the radiator 7 via a pipe, and the gas is finally discharged through a gas exhaust pipe 10. The end of the gas exhaust pipe 10 is connected to a tail gas treatment device with a known and mature structure.

[0035] This invention also provides a method for detecting fragrance loss during industrial fragrance addition, comprising the following steps:

[0036] Step 1: Connect the power supply to the temperature control box 6 to control the heating device 5 to enter the heating stage. After reaching the required temperature, maintain a constant temperature.

[0037] Step 2: Start the air pump 2, observe the reading of the flow meter 3 until the reading is within the set range, turn on the power to the first ethanol gas sensor 4, the second ethanol gas sensor 8 and the carbon dioxide gas sensor 9, and wait for the reading on the data monitoring panel 11 to stabilize.

[0038] Step 3: After the air intake is stabilized, the first ethanol gas sensor 4, the second ethanol gas sensor 8, and the carbon dioxide gas sensor 9 begin to record data. The data monitoring panel 11 records and displays the data readings of the first ethanol gas sensor 4, the second ethanol gas sensor 8, and the carbon dioxide gas sensor 9. Based on the liquid inlet parameters and exhaust parameters during the fragrance addition process, the amount of fragrance loss during the fragrance addition process is analyzed, i.e., the percentage of fragrance loss, thereby obtaining the effective absorption rate of fragrance during the fragrance addition process.

[0039] Example 1

[0040] This embodiment is designed based on the above technical solution. The gas pump 2 draws the gas to be tested at a certain flow rate. The flow rate of the gas to be tested is controlled between 200ml / min and 1000ml / min as needed. The flow rate change is monitored by the flow meter 3. The gas enters the first ethanol gas sensor 4 to measure the initial ethanol content E1ppm in the gas. The gas enters the heating section pipeline to heat the gas to a certain temperature. The heating temperature is set by the temperature control box 6. The temperature of the heating section is usually maintained at a high temperature level to ensure that the fragrance components in the gas are fully burned. The high-temperature gas after heating is quickly cooled to room temperature by the radiator 7 to avoid affecting the use of the sensor due to temperature rise. The ethanol content E2ppm in the gas after heating is measured by the second ethanol gas sensor, and the carbon dioxide content Cppm in the gas after heating is measured by the carbon dioxide gas sensor 9. The gas is discharged through the gas outlet pipeline 10. To avoid pollution, the discharged gas needs to be rendered harmless. The ethanol content E1, ethanol content E2, and carbon dioxide content C are read on the data monitoring panel 11.

[0041] In addition, the carbon dioxide content (C0ppm) in the detection environment needs to be measured. It is also known that the fragrance inlet flow rate during the fragrance addition process is Lkg / h, the mass percentage of carbon in the fragrance is a, the ethanol content in the fragrance is L1kg / h, and the exhaust volume of fragrance-containing gases during the fragrance addition process is Gm. 3 / h, the molecular weight of ethanol is eg / mol, the molecular weight of carbon is cg / mol, and the molar volume of the gas at room temperature is gL / mol. Analysis shows that the percentage S of fragrance loss during the fragrance addition process can be calculated using the following formula.

[0042]

[0043] The calculation results will be displayed in real time on the data monitoring panel so that staff can understand the real-time changes in the percentage of fragrance loss during the industrial fragrance addition process.

[0044] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
