Description

A kind of egg device for detecting respiratory

Technical field

This utility model relates to egg technical field of nondestructive testing, particularly relates to a kind of egg device for detecting respiratory.

Background technology

At present, fruit and vegerable breathe conventional assay method settled process, air-flow method, infrared method and gas chromatography etc.. The device of settled process is fairly simple, will place in obturator by object under test, extract the inside through after a while Gas, measure its concentration；The device of air-flow method mainly includes equipped with sodica calx and the dress of 20% sodium hydroxide Put and be attached with respiratory chamber, absorption tube and atmosphere sampling instrument, make air pass sequentially through each device, utilize big The eudiometry that gas sampling instrument is collected breathes numerical value.

Lian Xijun et al. utilizes air-flow method to measure Fructus Mali pumilae and the respiratory intensity of Rhizoma Dioscoreae esculentae, and during to gas balance Between, carbon dioxide collection time etc. affects the accuracy correlative factor of respiratory intensity and carried out labor.[even Happiness army, Lu Xiaoxiang, Yang Xinbo etc. air-flow method measures the determination [J] of parameter in Respiration Intensity of Apple. Yantai fruit tree, 2007,4:18-20；Lian Xijun, king, Yang Xinbo etc. respiration intensity of sweet potato air-flow method location parameter is studied [J]. food research and development, 2008,29 (7): 25-28].Zhao Meixia et al. utilizes carbon dioxide analyser pair The location parameter of respiratory intensity of fruit is inquired into, and experimentation shows, respiratory chamber remaining space and mensuration fruit The ratio of reality is proper between 2:1 to 4:1, gas flow rate be 400ml/min conveniently etc..[Zhao Meixia, Yan Shijie, Xiao Lixia etc. infrared CO2 analyzer measures respiratory intensity of fruit parameter pre-test [J]. modern instrument, 2005,2:30-32].

Relevant egg respiration detection method, Liu Meiyu et al. self-control bottle respirator detection device, experimental group egg is put Enter in bottle respirator, bottle respirator is put under reserve temperature, seal 4h, take out at sebific duct with disposable syringe Take gas 1mL in bottle, survey CO with the gas chromatograph installing nickel reburner additional₂Volume fraction.[Liu Meiyu, Lian Hai Flat, Peng Zengqi etc. temperature is on shell egg respiratory intensity brown, white and the impact [J] of storage quality. food research with open Send out, 2012,33 (12): 105-108.].Wang Qiaohua et al. builds non-damage micrometering test platform, monitors in real time Egg and the O of extraneous microenvironment₂Exchange rate and exchange intensity.[Wang Qiaohua, Zhang Tao, Ma Meihu. based on non- Damage micrometering technical monitoring storage period egg oxygen breathes rule [J]. Transactions of the Chinese Society of Agricultural Engineering, and 2014,30 (5): 255-261.】.The method advantage is that can to monitor gas in real time be outer row or absorption, and shortcoming is probe and chicken Egg must be carried out in being immersed in some solution, and testing cost is expensive.

Although the operation of air-flow method adds list, but accuracy is poor；Air-flow method, operates relatively easy, and cost is relatively low, But whether its preparation of the chemical drugs in device is the most troublesome, and cannot react in judgment means Entirely；Infrared method and gas chromatography accuracy are higher, but expensive equipment, and cost is high, and the time needed Longer.No matter utilize gas analyzer for CO2 or gas chromatograph to survey amount of carbon dioxide, not only increase reality The complexity tested, too increases the cost of experiment simultaneously.

Through retrieval, the most domestic not yet discovery is relevant to be applied to produce reality for egg device for detecting respiratory.
