In the commercial production of packaging for foodstuff, all need the detection wrappage of food being carried out to gas penetration potential, produce with the situation preventing food spoilage, external most of ventilation property test device structures all more complicated, and control not easily, cost is high, and is not suitable for middle-size and small-size food processing factory.
Summary of the invention
Object of the present invention is just to provide a kind of ventilation property test device for wrappage to solve the problem.
In order to achieve the above object, present invention employs following technical scheme:
A kind of ventilation property test device for wrappage, comprise permeability meter, heating coil and U-shaped glass tube, described permeability meter is arranged in constant temperature pond, described permeability meter comprises high pressure air cavity and low pressure air cavity, tested wrappage are arranged between described high pressure air cavity and described low pressure air cavity, described high pressure air cavity is positioned at the bottom of described low pressure air cavity, described high pressure air cavity is connected with the first end of described heating coil and the first gas output end respectively, second end of described heating coil is connected with draft tube, described infrabar chamber is connected with described U-shaped glass tube and the second gas output end respectively, band color wine essence is provided with in described U-shaped glass tube.
Particularly, gas admittance valve and pressure gauge is provided with between the second end of described heating coil and described draft tube.
Particularly, between described high pressure air cavity and the first gas output end, be provided with first row air valve, between described low pressure air cavity and the second gas output end, be provided with second row air valve.
Beneficial effect of the present invention is:
The present invention is used for the ventilation property test device of wrappage, and by the accurate measurement adopting permeability meter and some annexes can complete gas penetration potential, its structure is simple, and production cost is lower, and easy to operate, has the value promoted the use of.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention for the ventilation property test device of wrappage.
In figure: 1-draft tube, 2-pressure gauge, 3-gas admittance valve, 4-second row air valve, 5-permeability meter, 6-heating coil, 7-U type glass tube, 8-first row air valve, 9-constant temperature pond.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, the present invention is used for the ventilation property test device of wrappage, comprise permeability meter 5, heating coil 6 and U-shaped glass tube 7, permeability meter 5 is arranged in constant temperature pond 9, permeability meter 5 comprises high pressure air cavity and low pressure air cavity, tested wrappage are arranged between high pressure air cavity and low pressure air cavity, high pressure air cavity is positioned at the bottom of low pressure air cavity, high pressure air cavity is connected with the first end of heating coil 6 and the first gas output end respectively, second end of heating coil 6 is connected with draft tube 1, infrabar chamber is connected with U-shaped glass tube 7 and the second gas output end respectively, band color wine essence is provided with in U-shaped glass tube 7.
Gas admittance valve 3 and pressure gauge 2 is provided with between second end of heating coil 6 and draft tube 1.Be provided with first row air valve 8 between high pressure air cavity and the first gas output end, between low pressure air cavity and the second gas output end, be provided with second row air valve 4.
When the present invention works, first wrappage are placed between high pressure air cavity and low pressure air cavity, open gas admittance valve 3 and second row air valve 4, start test gas and drive away inner air and purifying apparatus, through after a period of time, the gas penetration potential of gas to wrappage reaches stable, close second row air valve 4, stop test, and enter formal measurement, carry out record to the difference in height of alcohol liquid at set intervals, repetitive measurement obtains multiple experiment sample, and calculates plastic sheeting Air permenbility and ventilative constant accordingly.
