Description
Technical field
The present invention relates to a kind of method for processing high-quality edible oil.
Background technology
Edible vegetable oil main cause of becoming sour is contacted with oxygen in air, makes in oil unrighted acid that oxidation occur anti-
Should, peroxide is formed after decomposition, and finally producing grease has penetrating odor oxidation product, is formed serious " rancid
Taste ", grease is set to lose edibility.Edible oil shelf life is packed to extend, various antioxidants are generally added, the purpose is in
Disconnected oxidation chain reaction, prevents peroxide from being formed.In recent years because consumer's ambition safety " natural product ", enterprise will act in accordance with trend and add
Add natural, but corresponding cost is higher at present.
Oxidation of Fat and Oils is also known as fat rancidity.Free fatty is generated after lipolysis, aliphatic acid is divided into " saturated fatty acid "
" unrighted acid ", wherein unrighted acid are under the effect such as light, oxygen, it is easier to oxidation slowly occurs and makees
With, and hydroperoxides are generated, hydroperoxides are cracked into low molecular aldehyde, ketone, acid etc. again rance product, this mistake
Journey is referred to as the oxidative rancidity of fat.It is bad to health.
Nitrogen is the main component of air, about accounts for 70%, and for chemical property than relatively inert, edible oil inflated with nitrogen can be to prevent
Oxidation, beneficial to preservation and keep flavor.The nitrogen to dissociate in air, one regards a kind of lazy gas as to by people.It is seemingly
What is all lost interest in, neither helps to burn, does not also sustain life.Nitrogen is a kind of colourless odorless gas at normal temperatures
Body, -209.8 DEG C of fusing point, -195.6 DEG C of boiling point.Solubility very little in water.Nitrogen can be liquefied as white liquid under extremely low temperature
Body even forms white crystalline solid.Commercially available nitrogen is all contained in black gas bottle and preserved.It can not burn, also not support to fire
Burn, be not readily dissolved in water.Nitrogen chemical property very inertia, is not easy and other substance reactions.
So if exist when packing edible oil by nitrogen-rich gas（Nitrogen charging）To reduce oxygen concentration, can reduce edible
Vegetable oil contacts with oxygen, so as to delay oxidative rancidity, and anti-oxidant important measures.Because the growth of many biologies is all to need
Oxygen is wanted, after being filled with nitrogen, the oxygen in bag can be excluded, slow down oxidation, reducing oxygen basis for the survival does not have
, meanwhile, nitrogen is a kind of very inactive material, and most materials will not all react with it under normal temperature, normal pressure.
Edible oil tinning finishes in backward bottle and is filled with nitrogen, makes oxygen in air and edible oil in bottle be replaced out,
The residual oxygen of head space in bottle is set to be less than 3%, then gland seals, and so on the one hand causes the oxygen residual of bottle internal oxidition edible oil very
Low, edible oil is not available for the source of oxygen of reaction；On the other hand, nitrogen forms nitrogen envelope in the head space part of bottle, has obstructed oxygen
Contact of the gas with edible oil, has reached protection edible oil, the effect for preventing edible oil from aoxidizing, while can avoid artificial anti-oxidant
The use of agent is to hidden danger caused by health.
The content of the invention
Reach more conducively preservation raising food by being filled with low temperature nitrogen in edible oil it is an object of the invention to provide one kind
With the method for the processing high-quality edible oil of oil quality.
The object of the present invention is achieved like this, the method for described processing high-quality edible oil, comprises the following steps：1）
The device of manufacture processing high-quality edible oil first, the device of described processing high-quality edible oil include oil cauldron, regulation oil pump
With low temperature nitrogen charger, the nitrogen of the interior filling of low temperature nitrogen charger is low temperature nitrogen, and regulation oil pump is fixedly connected with edible oil oil inlet pipe, energy
Edible oil is pumped into oil cauldron；Edible oil oil inlet pipe is linked into oil cauldron；Liquid-level switch is set in oil cauldron；The nitrogen of low temperature nitrogen charger
Gas inlet pipe is connected to oil cauldron, and escape pipe is fixedly connected with oil cauldron, the external unidirectional air outlet valve of escape pipe；Eaten provided with high-quality oil cauldron bottom
With oil export, oil cauldron is the oil cauldron provided with heat-insulation layer；2）Pass through the step 1 prepared）Processing high-quality edible oil dress
Edible oil is pumped into oil cauldron by the regulation oil pump in putting, when edible oil has arrived setting liquid level, liquid-level switch action control governor oil
Pump oil-feed, start low temperature nitrogen charger and low temperature nitrogen is filled with to the edible oil in oil cauldron and is stirred, in the edible oil in oil cauldron
Oxygen excludes from escape pipe through external unidirectional air outlet valve, the oxygen in edible oil is removed completely, prevents edible oil from aoxidizing, more
Beneficial to the quality for preserving raising edible oil, reach more permanent storage.
Beneficial effects of the present invention are：Edible oil by regulation oil pump is pumped into oil cauldron by the present invention, when edible oil is to setting
When determining liquid level, liquid-level switch action control regulation oil pump oil-feed, and start low temperature nitrogen charger the edible oil in oil cauldron is filled with it is low
Warm nitrogen is simultaneously stirred, and is removed the oxygen in edible oil, is prevented edible oil from aoxidizing, and more conducively preserves the product for improving edible oil
Matter, reach more permanent storage.The present invention has the advantages that simple in construction, technique is simple, easy to use.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The structure to the present invention and operation principle and the course of work are described in detail with reference to the accompanying drawings and examples：
As shown in figure 1, the method for processing high-quality edible oil of the present invention, oil is pumped into by regulation oil pump by edible oil
Pot, when edible oil has arrived setting liquid level, liquid-level switch action control regulation oil pump oil-feed, and start low temperature nitrogen charger to oil cauldron
In edible oil be filled with low temperature nitrogen and be stirred, remove edible oil in oxygen, prevent edible oil from aoxidizing, more conducively preserve
The quality of edible oil is improved, reaches more permanent storage.The device of processing high-quality edible oil of the present invention includes oil cauldron
1st, regulation oil pump 2 and low temperature nitrogen charger 4, the nitrogen of filling can be low temperature nitrogen or liquid nitrogen in low temperature nitrogen charger, its design feature
It is fixedly connected for regulation oil pump 2 and edible oil oil inlet pipe 3, edible oil 10 is pumped into oil cauldron 1；Edible oil oil inlet pipe 2 is linked into oil
In pot 1；Liquid-level switch 5 is set in oil cauldron 1；The nitrogen inlet 6 of low temperature nitrogen charger 4 is connected to oil cauldron 1, and escape pipe 7 is solid with oil cauldron 1
Fixed connection, the external unidirectional air outlet valve 11 of escape pipe 7；The bottom of oil cauldron 1 is provided with high-quality and eats oil export 9, and oil cauldron is provided with insulation
The oil cauldron of layer 8.
Operation principle of the present invention is：After edible oil 10 is pumped into oil cauldron by regulation oil pump, when oil has arrived setting liquid level, liquid
Bit switch action control regulation oil pump oil-feed simultaneously starts low temperature and rushes nitrogen machine and pour low temperature to the edible oil of oil cauldron by nitrogen inlet 6
Nitrogen is simultaneously stirred, and oxygen excludes from escape pipe 7 through external unidirectional air outlet valve 11 in the edible oil in oil cauldron, makes edible oil
In oxygen remove completely, edible oil improved higher quality, reached more permanent storage.
