Abstract
The utility model belongs to the production field of maize germ oil and particularly relates to a nitrogen dispersion injector for refreshing edible oil. In the technical scheme, the nitrogen dispersion injector for refreshing edible oil comprises a pipeline which is provided with flanges at two ends, and a porous dispersion rod arranged inside the pipeline, an air inlet hollow screw rod is arranged on the porous dispersion rod, and the porous dispersion rod is connected with the pipeline by a bracket. In the technical scheme, nitrogen protection is carried out, namely air is replaced by nitrogen so as to isolate the oil from being contacted with oxygen, more importantly, the nitrogen forms fine air flows after passing through the dispersion injector, and then the air flows enter the oil body and are mixed so as to replace and remove the oxygen entrained, adsorbed and dissolved in the oil to the maximum extent and obtain superexcellent oil refreshing effect.
Description
Technical field
The utility model belongs to the maize germ oil production field, relates in particular to a kind of fresh-keeping nitrogen of edible oil that is used for and disperses injector.
Background technology
Maize germ is a kind of nutritious grease, because be rich in unrighted acid, tocopherol, phytosterol and be subjected to liking of people.
Oxidation is to influence edible oil freshness most critical sexual factor, and small-molecule substances such as the aldehyde that decomposition produces in the oxidizing process, ketone, acid have the intense stimulus smell, influence mouthfeel, should not be suitable for.Maize germ oil is oxidation very easily, and its oxidation, rancidity are the fastest during all oil is planted.The conventional method that solves the edible oil oxidation deterioration is to adopt the mode of adding the artificial antioxidant-ditert-butylhydro quinone (TBHQ) that synthesizes to store.And long-term excessive absorption antioxidant TBHQ can cause certain infringement to health.The state food safety law all has the strict statute of limitations for the man-made additive of food.Thereby in grease processing and storage, adopt nitrogen protection method more, and the advantage of this method is not add the chemical synthesis additive, utilizes the inertia of natural nitrogen, and principle not volatile, air-isolation reaches fresh-keeping effect.Promptly adopt nitrogen that the oxygen in the oil and fat vessel is replaced as much as possible, got rid of, avoid grease to contact,, keep mouthfeel, taste and the abundant nutrition of edible oil to prevent the bad change of oil quality with oxygen, thus more natural, healthy.
The nitrogen protection method that has adopted at present is the nitrogen coverage mode, and so-called " sprinklings " all is above pasta, makes nitrogen be full of the space of storage tank or pipeline, with original air discharge, thereby prevents the oxidation of grease, plays certain preservation.But, at normal temperatures and pressures, can adsorb the oxygen that is dissolved with 0.2～0.4Kg in the 1kg edible oil, this a spot of oxygen is enough to make particularly corn oil oxidation deterioration of edible oil, therefore, must study and be more suitable for fresh-keeping new method of corn oil and device.
Summary of the invention
The purpose of this utility model is, overcomes the deficiencies in the prior art, provides a kind of fresh-keeping nitrogen of edible oil that is used for to disperse injector.This scheme is not simple " nitrogen filled protection ", promptly replaces air with nitrogen, and the isolation grease contacts with oxygen; The more important thing is nitrogen is passed through to disperse to form trickle air-flow behind the injector, charge among the oil body, mix mutually, the oxygen of carrying secretly, adsorbing and be dissolved in the grease is replaced most possibly, got rid of, to obtain excellent grease fresh-keeping effect.
For solving the problems of the technologies described above, the technical solution of the utility model is: be used for the fresh-keeping nitrogen of edible oil and disperse injector, comprise that two ends are that the pipeline of flange and the porous that is positioned at pipe interior are disperseed rod, described porous disperses on the rod air inlet cored screw is arranged, and porous disperses to be connected by support between rod and the pipeline.
It is diatomite sand filtration rod, ceramic capillary filter stick, macromolecular filter membrane, porous, expanded material or stainless steel porous membrane that porous described in the utility model is disperseed rod.
It is 10～100 microns that porous described in the utility model is disperseed the aperture of rod.
It is circular, polygon or petal that porous described in the utility model is disperseed the cross section of rod.Because porous disperses the surface area of rod to increase, making in the unit interval increases towards the nitrogen amount, has also improved operating efficiency when discharging in the oil more oxygen.
Nitrogen described in the utility model disperses injector to be series connection and/or combination in parallel.Many group nitrogen dispersers are united use, have improved towards nitrogen effect and operating efficiency.
The beneficial effects of the utility model are: are used for the fresh-keeping nitrogen of edible oil and disperse injector, and simple in structure, easy to use, adopt the new nitrogen of this practicality to disperse oxygen content＜0.008% in the maize germ oil that injector processes; Adopt that oxygen content is 0.3% in the existing maize germ oil that fills the processing of nitrogen coverage mode;
0.12 (mgKOH/g) when acid value is by can in 18 months in the bottled maize germ oil that adopts the utility model nitrogen to disperse injector to process increases to 0.18 (mgKOH/g), increases by 0.5 times; Adopt the existing rice germ oil that fills the processing of nitrogen coverage mode acid value in 18 months to increase to 1.90 (mgKOH/g) by at that time 0.12 (mgKOH/g), increase by 14.8 times, the speed of becoming sour is 29.6 times of the present invention.
