Abstract
The utility model belongs to the production field of maize germ oil, and particularly relates to a nitrogen-dispersing ejector and a maize germ oil low-temperature fresh keeping device. The technical scheme of the utility model is as follows: the nitrogen-dispersing ejector comprises a pipeline with flanges at two ends and a multi-hole dispersing stick which is arranged in the pipeline, wherein the multi-hole dispersing stick is provided with an air charging hollow screw rod, and the multi-hole dispersing stick is connected with the pipeline by a bracket. The utility model is simple in structure, and convenient to use. The oxygen content in the maize germ oil processed by the maize germ oil low-temperature fresh keeping device is less than 0.008%; and the oxygen content in the maize germ oil processed by the existing nitrogenizing and covering mode is 0.3%.
Description
Technical field
The utility model belongs to the maize germ oil production field, relates in particular to a kind of nitrogen and disperses injector and maize germ oil preservation by low temperature device.
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 nitrogen to disperse injector and maize germ oil preservation by low temperature device.It is not simple " nitrogen filled protection " for this device, 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: nitrogen disperses 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.
The utility model also provides maize germ oil preservation by low temperature device, comprise oil tank, described oil tank is contacted successively and is connected with filter, cooling cooler, at least one nitrogen dispersion injector by pump, described nitrogen disperses injector to be connected with bottle placer, and described nitrogen disperses the air inlet cored screw on the injector to be connected with nitrogen pipeline.Make nitrogen form trickle air-flow behind the injector, and mix, thereby miscible oxygen in grease is got rid of, reach the purpose that prevents the bad change of corn oil oxidation with grease liquid formation turbulent flow through disperseing.The temperature of cooling cooler is controlled at low scope, according to Various Seasonal, all is controlled between 7～15 ℃.
Nitrogen described in the utility model disperses injector to be series connection and/or combination in parallel.
The beneficial effects of the utility model are: comprise that nitrogen disperses the maize germ oil preservation by low temperature device of injector, simple in structure, easy to use, oxygen content＜0.008% in the maize germ oil that employing the utility model maize germ oil preservation by low temperature device is processed; 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 maize germ oil preservation by low temperature device to be processed 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.
