Abstract
The utility model discloses a respiratory chamber for determining the respiration intensity of fruits and vegetables. The respiratory chamber comprises a sample chamber and a rubber plug, wherein the sample chamber comprises a barrel and an upper cover, the upper cover is connected at an opening in the upper end of the barrel in a sealing manner, a through hole is formed in the upper cover, and the rubber plug is connected at the through hole in a sealing manner. When the respiratory chamber is used, the fruits and vegetables are placed in the sample chamber, are sealed and stand still, then a right amount of headspace air in a box is taken by an identical needle tube through the rubber plug, and a gas chromatographic method is used for determining the respiration intensity of fruits and vegetables. The respiratory chamber is novel in structure, simple and convenient to machine, convenient to use, low in cost, safe, practical and suitable for the determination of respiration intensity of the fruits and vegetables in teaching, scientific research and production practice.
Description
Technical field
The utility model belongs to fruit and vegetable storage and transportation and learns research field, relates to fruits and vegetables respiratory intensity instrument, particularly a kind ofly processes easy, practical and convenient, the high novel mensuration fruits and vegetables respiratory intensity respiratory chamber of mensuration degree of accuracy.
Background technology
Respiration (respiration) is the essential characteristic of organism vital movement, also is one of most important physiological activity of carrying out after gathering of fruits and vegetables.Can weigh the respiratory power of fruits and vegetables by measuring respiratory intensity (or address is inhaled speed, respiration rate), understand postharvest fruit and vegetable vital movement state, for low temperature and controlled atmosphere storing and respiration heat are calculated the theoretical foundation that provides necessary.The experimental teaching of fruit and vegetable storage and transportation, scientific research and production practices all be unable to do without the mensuration of fruits and vegetables respiratory intensity.Measure the fruits and vegetables respiratory intensity and need an airtight respiratory chamber, all adopted loam cake to be furnished with the glass exsiccator of plug as measuring the respiratory chamber that the fruits and vegetables respiratory intensity is used in the past, but the glass exsiccator is damaged easily, and it is poorly sealed, internal volume can't accurately be measured, it is also inhomogeneous to take a sample, and maximum bottleneck is that also glass exsiccator volume is bigger, can't be few at fruit and vegetable materials or situation that respiratory intensity is little under carry out the mensuration of respiratory intensity.At existing problem in the above-mentioned prior art, a kind of novel mensuration fruits and vegetables respiratory intensity respiratory chamber of research and design, existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the purpose of this utility model provides a kind of novel mensuration fruits and vegetables respiratory intensity respiratory chamber.Exist in the prior art in order to solve: measure the fruits and vegetables respiratory intensity with respiratory chamber easily damaged, poorly sealed, internal volume can't accurately be measured, carry out problem such as respiratory intensity mensuration under inhomogeneous, few at fruit and vegetable materials or the situation that respiratory intensity is little of taking a sample also.
Technical solution of the present utility model is achieved in that
A kind of mensuration fruits and vegetables respiratory intensity respiratory chamber is made up of sample chamber and plug, and described sample chamber is made up of cylindrical shell and loam cake, and described loam cake is sealedly connected on cylindrical shell upper end open place, covers on described and is provided with through hole, and described plug is sealedly connected on the described through hole.
In the technical solution of the utility model, described plug is preferably natural plug or butyl rubber plug.
In the such scheme, described butyl rubber plug is transfusion flange butyl rubber plug.
In the further preferred version of the present utility model, described sample chamber is the plastics crisper.The commercially available plastics crisper with sealing property can be adopted in described sample chamber, preferably adopts LeKouLeKou (Lock ﹠amp; Lock) the plastics crisper of brand.During preparation, drill through through hole covering of plastics crisper, the polishing edge gets final product with plug sealing through hole.The big I of described plastics crisper and plug is selected arbitrarily according to what and characteristic of experiment material.
The big I of the utility model sample chamber and plug is selected arbitrarily according to what and characteristic of experiment material.
Respiratory chamber of the present utility model during use, adds suitable quantity of water earlier in the sample chamber, add a cover the loam cake of jam-pack plug on the through hole, checks the sealing of respiratory chamber; After confirming that sealing is good, outwell the water in the sample chamber, put into sample (fruits and vegetables), after a period of time is placed in sealing, rock respiratory chamber along continuous straight runs and vertical direction under the 3-5 respectively, mix so that breathe indoor gas, penetrate plug with needle tubing then and get head space gas, with gas chromatography determination fruits and vegetables respiratory intensity.
The utility model utilizes needle tubing to prick into plug and can take a sample (the respiratory chamber head space gas that mixes), and sampling is simple, accurately; Form sample chamber and the big I of plug of respiratory chamber and select arbitrarily according to what and characteristic of experiment material, solved and measured the fruits and vegetables respiratory intensity with respiratory chamber is easy damaged, poorly sealed, internal volume can't accurately be measured, it is inhomogeneous to take a sample, measurement result is subjected to problems such as raw material restriction in the past.
The utility model, novel structure, processing are easy, easy to use, with low cost, safe and practical, are applicable to that the fruits and vegetables respiratory intensity in teaching, scientific research and the production practices is measured.
