Description

A kind of fruits and vegetables respiration monitoring device

Technical field:

The utility model belongs to fruit and vegetable storage and transportation and learns research field, relates to a kind of fruits and vegetables respiration monitoring device, relates in particular to the determinator of respiratory intensity in a kind of fruit vegetables storing and the transportation.

Background technology:

Respiratory metabolism is the important physiological activity of back fruits and vegetables in storage and transportation of gathering, and is to cause one of fruits and vegetables loss key factor.Respiratory intensity and dynamic change are studied, helped people to understand the postharvest fruit and vegetable physiological status, for preservation techniques such as low temperature, controlled atmosphere and decompression provide gross data.

At present the annual fruits and vegetables proportion of goods damageds of China are 25.0-30.0%, can effectively reduce the respiratory intensity of fruits and vegetables by preservation technique, and this can not only reduce the fruit and vegetable storage and transportation loss, increases orchard worker's income, and developing in a healthy way for China's fruits and vegetables industry simultaneously also is of great significance.

The fruits and vegetables respiratory intensity is measured and can be divided into two kinds of air-flow method and settled process, and air-flow method measurement result is accurate, but equipment is complicated; Settled process equipment is simple, easy to operate, in research and production, often be used, but also exist the glass exsiccator frangible, move problems such as inconvenience.

Summary of the invention:

For solving the existing in prior technology deficiency, the purpose of this utility model is to provide a kind of fruits and vegetables respiration monitoring device, respiratory intensity in fruit vegetables storing and the transportation is directly measured, thus the METHOD FOR CONTINUOUS DETERMINATION of realization fruits and vegetables respiratory metabolism.

For achieving the above object, the utility model adopts following technical measures:

A kind of fruits and vegetables respiration monitoring device is made up of base and sample chamber, and base is placed on the table, and the sample chamber is fixed on the base; Described sample chamber comprises the cylindrical shell of a hollow, the gluing loam cake in cylindrical shell top, and the gluing baffle plate of cylindrical shell middle and lower part two medial surfaces, orifice plate is placed on the baffle plate, and insert in the base groove cylindrical shell bottom; Described base comprises a lower cover, forms groove between gluing Internal baffle and outer baffle on the lower cover, and recess width is slightly larger than cylindrical shell thickness, and cylindrical shell inserts groove and the base of smearing vaseline by the bottom and is tightly connected, and contains the alkali lye double dish and covers and be placed on lower cover central authorities.

Compared with prior art, the utlity model has following advantage:

1, simple in structure, sturdy and durable.The utility model adopts organic glass to make, and is simple in structure, only need to install get final product according to synoptic diagram, and not fragile when moving.

2, reasonable in design, easy to use.The utility model adopts base and sample chamber separate design, and the convenient Sheng alkali lye double dish lid that takes out carries out METHOD FOR CONTINUOUS DETERMINATION.

3, of many uses, practical.The utility model both can be used for indoor measurement, also can be used for field measuring, was applicable to the applied research of aspects such as fruit and vegetable storage and transportation, plant physiology and edaphology.

Description of drawings

Fig. 1 is a kind of structural representation of fruits and vegetables respiration monitoring device

Embodiment:

Below in conjunction with accompanying drawing and example the utility model is described in further details.

As shown in Figure 1, a kind of fruits and vegetables respiration monitoring device is made up of base and sample chamber, and base is placed on the table, and the sample chamber is fixed on the base.

The sample chamber comprises the square cylindrical shell 3 of a hollow, the gluing loam cake 1 in cylindrical shell 3 tops, the gluing baffle plate 5 of cylindrical shell 3 middle and lower parts two medial surfaces; The sample chamber is inverted and is placed on the desktop, and orifice plate 4 enters cylindrical shell 3 along 5 liang of medial surfaces of not gluing baffle plates, and rotation orifice plate 4 is to baffle plate 5 places, and the sample chamber is just putting then that orifice plate 4 is placed on the baffle plate 5, and insert in the base groove 9 cylindrical shell 3 bottoms.

Base comprises a lower cover 2,

Internal baffle

8 and 7 of outer baffles gluing on the lower cover 2 form groove 9, groove 9 width are slightly larger than cylindrical shell 3 thickness, and cylindrical shell 3 inserts the groove 9 of smearing vaseline by the bottom and is tightly connected with base, contain alkali lye double dish lid 6 and are placed on lower cover 2 central authorities.

Cylindrical shell 3, loam cake 1, lower cover 2, orifice plate 4, baffle plate 5, Internal baffle 8 and outer baffle 7 all adopt organic glass to make, and its big I changes with fruits and vegetables sample size to be measured.

Establish blank group and two groups of devices of sample sets during use, contain alkali lye double dish lid 6 and be placed on lower cover 2 central authorities, smear vaseline in 7 grooves 9 of Internal baffle 8 and outer baffle; The sample chamber is inverted and is placed on the desktop, and fruits and vegetables sample to be measured is placed on the loam cake 1 in the sample sets, does not put into fruits and vegetables sample to be measured in the blank group; Orifice plate 4 enters cylindrical shell 3 along 5 liang of medial surfaces of not gluing baffle plate, and rotation orifice plate 4 is to baffle plate 5 places, and the sample chamber is just putting fruits and vegetables sample then to be measured and orifice plate 4 is placed on the baffle plate 5; Cylindrical shell 3 inserts the groove 9 of smearing vaseline by the bottom and is tightly connected with base.

After leaving standstill 20-60min, take out and contain alkali lye double dish lid 6, alkali lye is moved on in the 250mL triangular flask, with 2 of phenolphthalein indicators, be terminal point with oxalic acid standard solution titration to pink color disappeared, record consumes oxalic acid standard solution volume, calculates the respiratory intensity of fruits and vegetables sample to be measured according to formula.
