Description
Technical field:
Vegetable oil inspiratory capacity is quickly detected using magnetic stirring apparatus the present invention relates to a kind of, more particularly to PET is avoided to pack
Plant oil bottle generates the rapid detection method that negative pressure causes depression.
Background technique:
The refining vegetable oil that vegetable oil especially newly refines out has oxidation and air-breathing unstability；Food-grade packing timber
Expect PET, that is, polyethylene terephthalate, currently on the market the Packaging Bottle filling for beverage or vegetable oil.
After PET Packaging Bottle filling and capping, oil bottle becomes a sealing system, influences bottle empty in addition to vegetable oil oil temperature changes
Outside shape, the pressure in the bottle is influenced there is also overhead gas in vegetable oil inhaler itself or oxidation reaction and is changed, the deformation of generation bottle body,
It rises phenomena such as flat, thus strong influence terminal market product quality.In the industry mainly using nitrogen-charging fresh-keeping mode ensure oil product and
Bottle-type presentation quality；Currently, a kind of not yet quickly detect nitrogen-charging fresh-keeping effect method, it would therefore be highly desirable to develop a kind of scientific, letter
Just PET packs vegetable oil air-breathing quantity measuring method.
Summary of the invention:
Place that purpose of the invention is to overcome the shortcomings in the prior art, is to provide a kind of normal temperature and pressure vegetable oil
Inspiratory capacity rapid detection method cannot really reflect nitrogen charging effect in bottle after avoiding packaging vegetable oil nitrogen charging, to influence to produce
Product physical and chemical index and image appearance.
The following technical solution is employed for the technical problems to be solved by the invention to realize:
Vegetable oil inspiratory capacity rapid detection method under a kind of normal temperature and pressure, comprises the steps of:
(1) the vegetable oil to be measured injection test bottle five/everywhere that room temperature is mutually synthermal, and it is put into stirrer, use is close
Lidstock, sealing cover are equipped with 2 holes；
(2) in thermometer insertion one hole of sealing cover, test is put on magnetic stirring apparatus with bottle；
(3) Duan Shuizhu being injected into using pasteur pipet in transparent tracheae one end again, the other end is inserted on another hole of sealing cover,
Keep transparent tracheae, thermometer, bottleneck and seal cap sealing state；
(4) water column initial position is marked, magnetic stirring apparatus is started, adjusting blender stirring rotor speed produces tested vegetable oil
Raw vortex reaches maximum；Water column moves in transparent tracheae simultaneously；
(5) after the mobile stopping of water column in transparent tracheae, water column moving distance and vegetable oil oil temperature are recorded；
It (6) is vegetable oil to be measured air-breathing at normal temperatures and pressures after mobile distance is calculated multiplied by tracheae inner hole sectional area
Amount.
Specifically: moving distance L, using transparent tracheae inside radius R, according to formula V=π R2L calculates vegetable oil to be measured
Inspiratory capacity at normal temperatures and pressures.
Further technology: the transparent tracheae is hose, is supported in bending part using plastic circle ring fastener, rounding off.
