技术领域 technical field
本发明涉及测量装置领域，具体地讲，涉及一种便携式智能型果蔬呼吸强度测定装置及测定方法。 The invention relates to the field of measuring devices, in particular to a portable intelligent fruit and vegetable respiration intensity measuring device and a measuring method.
背景技术 Background technique
收获后的果蔬等园艺产品仍然是一个有生命的个体，为维持生命活动，必然要进行呼吸作用。呼吸强度是衡量果蔬等园艺产品呼吸作用的重要指标，测定呼吸强度可衡量呼吸作用的强弱，了解果蔬采后生理状态，为低温和气调贮运以及呼吸热计算提供必要的数据。因此，在研究或处理果蔬贮藏问题时，测定呼吸强度是经常采用的手段。呼吸强度一般以某一温度下，每千克果实每小时呼吸产生的二氧化碳毫克数表示。目前用来测定呼吸强度的方法主要有静止法、气流法、红外二氧化碳分析仪法、气相色谱法。静止法装置简单，但在封闭的环境中因二氧化碳含量升高会抑制果蔬的呼吸作用，因此静止法测得的结果不准确。气流法较静止法较为准确，但因为需要采用碱液吸收再用草酸滴定，所以不便于携带。红外二氧化碳分析仪法是在气流法的基础上改进而来，将末端的碱液吸收滴定改为红外二氧化碳分析测定，但其进气段依然采用高浓度碱液吸收空气中二氧化碳的方法，不便于携带，且存在安全隐患。气相色谱法结果准确，精度高，但所需气相色谱仪造价昂贵，无法携带使用。静止法和气流法得到的直接数据为滴定所用草酸的量，红外二氧化碳分析仪和气相色谱法得到的直接数据为二氧化碳含量，无论是那种数据都需要代入公式进行多次计算，增加出错几率同时也耗费了分析时间，无法第一时间获得测定结果。随着果蔬贮运保鲜技术研究和应用的需要，亟需研制一种既方便携带，又能直接获得呼吸强度结果的智能测定装置。 Harvested fruits and vegetables and other horticultural products are still living individuals, and in order to maintain life activities, respiration must be carried out. Respiration intensity is an important indicator to measure the respiration of horticultural products such as fruits and vegetables. Determination of respiration intensity can measure the strength of respiration, understand the physiological state of fruits and vegetables after harvest, and provide necessary data for low temperature and controlled atmosphere storage and transportation, and calculation of respiratory heat. Therefore, when studying or dealing with storage problems of fruits and vegetables, it is often used to measure respiratory intensity. Respiration intensity is generally expressed by the number of milligrams of carbon dioxide produced per kilogram of fruit per hour of respiration at a certain temperature. The methods currently used to measure respiratory intensity mainly include static method, air flow method, infrared carbon dioxide analyzer method, and gas chromatography. The static method has a simple device, but in a closed environment, the respiration of fruits and vegetables will be inhibited due to the increase of carbon dioxide content, so the measured results of the static method are not accurate. The air flow method is more accurate than the static method, but it is not easy to carry because it needs to be absorbed by lye and then titrated with oxalic acid. The infrared carbon dioxide analyzer method is improved on the basis of the airflow method, and the lye absorption titration at the end is changed to infrared carbon dioxide analysis and measurement, but the air inlet section still uses high-concentration lye to absorb carbon dioxide in the air, which is not convenient carry, and pose a safety hazard. Gas chromatography has accurate results and high precision, but the required gas chromatograph is expensive and cannot be used portablely. The direct data obtained by the static method and the air flow method are the amount of oxalic acid used for titration, and the direct data obtained by the infrared carbon dioxide analyzer and gas chromatography are the carbon dioxide content. No matter what kind of data it is, it needs to be substituted into the formula for multiple calculations, which increases the probability of error. The analysis time is also consumed, and the measurement results cannot be obtained in the first time. With the needs of the research and application of fruit and vegetable storage, transportation and fresh-keeping technology, it is urgent to develop an intelligent measuring device that is not only convenient to carry, but also can directly obtain the result of respiratory intensity.

具体实施方式 detailed description
下面结合实施例，进一步说明本发明。 Below in conjunction with embodiment, further illustrate the present invention.
参见图1和图2，本发明包括进气口，1所述进气口1连接一级二氧化碳吸收室2，所述一级二氧化碳吸收室2与所述二级二氧化碳吸收室3连通，所述二级二氧化碳吸收室3与缓冲室4连通，所述缓冲室4与样品室5连通，所述样品室5与干燥室6连通，所述干燥室6与测定分析室7连通，所述干燥室6连接有出气口8。 Referring to Fig. 1 and Fig. 2, the present invention includes an air inlet, 1 said air inlet 1 is connected to a primary carbon dioxide absorption chamber 2, and said primary carbon dioxide absorption chamber 2 communicates with said secondary carbon dioxide absorption chamber 3, said The secondary carbon dioxide absorption chamber 3 communicates with the buffer chamber 4, the buffer chamber 4 communicates with the sample chamber 5, the sample chamber 5 communicates with the drying chamber 6, and the drying chamber 6 communicates with the measurement analysis chamber 7, and the drying chamber 6 is connected with air outlet 8.
所述样品室5内设置有温度传感器10。 A temperature sensor 10 is arranged in the sample chamber 5 .
所述测定分析室7内设置有二氧化碳检测元件11。 The measurement and analysis chamber 7 is provided with a carbon dioxide detection element 11 .
所述测定分析室7内设置有气泵12。 An air pump 12 is provided in the measurement and analysis chamber 7 .
所述气泵12连接操作面板9。 The air pump 12 is connected to the operation panel 9 .
所述温度传感器10和二氧化碳检测元件11都连接微处理器13。 Both the temperature sensor 10 and the carbon dioxide detection element 11 are connected to a microprocessor 13 .
所述一级二氧化碳吸收室2和二级二氧化碳吸收室3内填充有二氧化碳吸收剂，用以吸收空气中的二氧化碳，使进入样品室5的空气中不再含有二氧化碳。装备可设置一个或多个二氧化碳吸收室，二氧化碳吸收室数量根据每个吸收室的体积和填充吸附剂的量来决定。一级二氧化碳吸收室2通过进气口1与大气连通，不同吸收室间有连接孔相连通。 The primary carbon dioxide absorption chamber 2 and the secondary carbon dioxide absorption chamber 3 are filled with a carbon dioxide absorbent to absorb carbon dioxide in the air, so that the air entering the sample chamber 5 does not contain carbon dioxide. The equipment can be equipped with one or more carbon dioxide absorption chambers, and the number of carbon dioxide absorption chambers is determined according to the volume of each absorption chamber and the amount of filled adsorbent. The primary carbon dioxide absorption chamber 2 communicates with the atmosphere through the air inlet 1, and there are connecting holes between different absorption chambers.
所述缓冲室4用于分隔样品室5和二氧化碳吸收室，避免二氧化碳吸附剂进入样品室5影响测定结果，同时也避免样品室5中产生的二氧化碳被吸附剂吸收影响测定结果。缓冲室4内注入一定量的蒸馏水，以隔绝二氧化碳吸收室和样品室5，同时可用于检测装置是否漏气。缓冲室4位于最后一级二氧化碳吸收室3之后，通过连接管与二级二氧化碳吸收室3相连通，连接管需插入液面以下。缓冲室4通过连接孔与样品室5相连通，连接孔应在液面以上。 The buffer chamber 4 is used to separate the sample chamber 5 and the carbon dioxide absorption chamber, so as to prevent the carbon dioxide adsorbent from entering the sample chamber 5 and affect the measurement results, and also prevent the carbon dioxide generated in the sample chamber 5 from being absorbed by the adsorbent to affect the measurement results. A certain amount of distilled water is injected into the buffer chamber 4 to isolate the carbon dioxide absorption chamber and the sample chamber 5, and can be used to detect whether the device is leaking. The buffer chamber 4 is located behind the last-stage carbon dioxide absorption chamber 3, and communicates with the second-stage carbon dioxide absorption chamber 3 through a connecting pipe, and the connecting pipe needs to be inserted below the liquid level. The buffer chamber 4 communicates with the sample chamber 5 through the connection hole, and the connection hole should be above the liquid level.
所述样品室5用于放置待测样品，样品称重后放入样品室内待测。样品室5带有可打开的密封盖，密封盖扣紧后需完全与外界隔绝，保证样品室5内气体与外界空气没有交换。密封方式可以采用水封，也可采用硅胶圈、橡胶圈等弹性材质的密封圈并配合卡扣进行密封。样品室5内安装有温度传感器10，用于测定样品室5温度和样品温度，通常样品温度应与样品室5温度一致。温度传感器10测定的温度数值传输到测定分析室的微处理器中用于对最终分析结果进行温度修正。 The sample chamber 5 is used to place the sample to be tested, and the sample is put into the sample chamber to be tested after being weighed. The sample chamber 5 is provided with an openable sealing cover, which needs to be completely isolated from the outside world after being fastened, so as to ensure that the gas in the sample chamber 5 does not exchange with the outside air. The sealing method can be a water seal, or a sealing ring of elastic material such as a silicone ring, a rubber ring, and a buckle for sealing. A temperature sensor 10 is installed in the sample chamber 5 for measuring the temperature of the sample chamber 5 and the sample temperature. Usually, the temperature of the sample should be consistent with the temperature of the sample chamber 5 . The temperature value measured by the temperature sensor 10 is transmitted to the microprocessor in the measurement and analysis room for temperature correction on the final analysis result.
所述干燥室6内填充有干燥剂，用于吸收被测气体中的水分。因气体中水分含量对二氧化碳检测元件的测定会产生不良影响，因此被检气体进入测定分析室前需进行干燥处理，以除去气体中的水分。 The drying chamber 6 is filled with a desiccant for absorbing moisture in the measured gas. Because the moisture content in the gas will have an adverse effect on the determination of the carbon dioxide detection element, the gas to be tested needs to be dried before entering the measurement and analysis chamber to remove the moisture in the gas.
所述测定分析室7内安装有气泵12、二氧化碳检测元件11、微处理器13，测定分析室7外部连接有控制面板9。气泵12用于为整个装置的气路提供动力，使外界空气通过进气口逐级进入二氧化碳吸收室、缓冲室、样品室、干燥室和测定分析室，最终通过出气口8排出。二氧化碳检测元件11用以检测气体中二氧化碳的含量。控制面板9用以输入待测样品重量、发送装置运行和停止等控制信号。 An air pump 12 , a carbon dioxide detection element 11 , and a microprocessor 13 are installed in the measurement and analysis chamber 7 , and a control panel 9 is connected to the outside of the measurement and analysis chamber 7 . The air pump 12 is used to provide power for the air circuit of the whole device, so that the outside air enters the carbon dioxide absorption chamber, the buffer chamber, the sample chamber, the drying chamber and the measurement and analysis chamber step by step through the air inlet, and is finally discharged through the air outlet 8. The carbon dioxide detection element 11 is used to detect the content of carbon dioxide in the gas. The control panel 9 is used to input control signals such as the weight of the sample to be measured, the operation and stop of the sending device, and the like.
本发明还提供了一种便携式智能型果蔬呼吸强度测定装置及测定方法，运行时，首先将已精确称重的水果（m克）放入样品室5内，盖好样品室5上盖，确保密封。然后通过操作面板9上的启动键启动装置。气泵12运行，将外界空气源源不断的带入装置中。二氧化碳检测元件11检测出装置启动时样品室二氧化碳的浓度（C0μl/L），并记录在微处理器13中。外界空气通过进气口1首先进入一级二氧化碳吸收室2，再进入二级二氧化碳吸收室3，此时空气中的二氧化碳全部被吸收剂吸附。无二氧化碳的空气进入缓冲室4后再进入样品室5。样品室5中的样品通过呼吸作用消耗氧气产生二氧化碳。样品室5中的气体进入放有干燥剂的干燥室6除去其中含有的水蒸气，然后进入测定分析室7。装置运行30分钟后，二氧化碳检测元件再次检测气体中的二氧化碳浓度（Cμl/L）并记录于微电脑处理器13中。被检测气体经气泵由出气口8排出。整个检测过程中，微处理器13每分钟记录一次样品室内的温度，待检测结束后自动计算出平均温度（T℃）。微处理器13将获得的各种数据代入预设程序中计算得出某一温度环境下果蔬的呼吸强度。 The present invention also provides a portable intelligent fruit and vegetable respiration intensity measuring device and a measuring method. During operation, firstly put the accurately weighed fruit (m grams) into the sample chamber 5, and cover the sample chamber 5 upper cover to ensure seal. Then start the device by the start key on the operation panel 9. The air pump 12 operates to continuously bring outside air into the device. The carbon dioxide detection element 11 detects the concentration of carbon dioxide in the sample chamber (C 0 μl/L) when the device is started, and records it in the microprocessor 13 . The outside air first enters the primary carbon dioxide absorption chamber 2 through the air inlet 1, and then enters the secondary carbon dioxide absorption chamber 3. At this time, all the carbon dioxide in the air is absorbed by the absorbent. The carbon dioxide-free air enters the buffer chamber 4 and then enters the sample chamber 5 . The sample in the sample chamber 5 consumes oxygen to produce carbon dioxide through respiration. The gas in the sample chamber 5 enters the drying chamber 6 containing a desiccant to remove the water vapor contained therein, and then enters the measurement and analysis chamber 7 . After the device runs for 30 minutes, the carbon dioxide detection element detects the carbon dioxide concentration (Cμl/L) in the gas again and records it in the microcomputer processor 13 . The gas to be detected is discharged from the gas outlet 8 through the gas pump. During the whole testing process, the microprocessor 13 records the temperature in the sample chamber every minute, and automatically calculates the average temperature (T° C.) after the testing is finished. The microprocessor 13 substitutes various data obtained into a preset program to calculate the respiration intensity of fruits and vegetables under a certain temperature environment.
样品呼吸强度计算公式为： The formula for calculating the breathing intensity of the sample is:
Q：样品呼吸强度（mg/kg/h）；S：气泵流量（ml/min）；C0：样品室初始二氧化碳浓度（μl/L）；C：运行30分钟后样品室二氧化碳浓度（μl/L）；m：样品质量（g）。 Q: Sample breathing intensity (mg/kg/h); S: Air pump flow rate (ml/min); C 0 : Initial carbon dioxide concentration in the sample chamber (μl/L); C: Carbon dioxide concentration in the sample chamber after 30 minutes of operation (μl/ L); m: sample mass (g).
