Description
Technical field
The present invention relates to waste oil detection technique, particularly a kind of capacitive quick waste oil detection method.
Background technology
Waste oil is actually the concept of a general reference, is people's common names for all kinds of poor oil in life.Generally, waste oil can be divided into following a few class: one is the waste oil of narrow sense, by the greasy floating thing in sewer or by the leftovers of hotel, restaurant, leftovers (common name swill) oil through simply processing, extracting; Two is pork inferior, haslet, pigskin processing and the oil of output after refining; Three is exceed after regulation requires for the oily access times of fried food, then is reused or toward the oil reused after wherein adding some fresh oils.Many businessmans buy waste oil because it is cheap, and interests are ordered about!
Harm: waste oil is quality extreme difference, extremely unhygienic, the unedible oil of peroxide value, acid value, moisture severe overweight.It contains toxin, flows to rivers and can cause water nutrition, once edible, then can destroy white blood cell and alimentary canal mucous membrane, cause food poisoning, even carcinogenic.The fried Cargo Oil prolonged and repeated use at high operating temperatures of one of " excessively rape oil ", contact with the oxygen in air, be hydrolyzed, be oxidized, the complex reaction such as polymerization, oily viscosity is caused to increase, color and luster is deepened, peroxide value raises, and produces the material of the irritant smell such as some volatile matters and aldehyde, ketone, lactone, and these materials have carcinogenesis.The toxicity of main harm the thing------aflatoxins in " swill oil " is then 100 times of arsenic.
Existing disclosed waste oil is differentiated general by seeing, hearing, taste, listen, ask that five aspects can be differentiated.
At a glance.See transparency, the transparent shape of pure vegetable oil, in process of production owing to being mixed into the things such as alkali fat, wax, impurity, transparency can decline; See color and luster, pure oil is colourless, and in process of production because the pigment in oil plant is dissolved in oil, oil just can be with look; See sediment, its principal ingredient is impurity.
Two hear.Often kind of oil has smell unique separately.Can drip one or two oil dripping on palm, both hands close up friction, and adstante febre carefully hears its smell.Have the oil of peculiar smell, illustrate that quality has problem, frowzy is exactly probably waste oil; If there is the smell of mineral oil more can not buy.
Three taste.Get an oil dripping with chopsticks, carefully taste its taste.The acidulated oil of mouthfeel is substandard product, has the oil of burnt bitter taste to become sour, and has the oil of peculiar smell may be " waste oil ".
Four tins: get the oil one or two bottom oil reservoir, be coated on the inflammable scraps of paper, light and listen its sound.Burning is normal is specification product without sound; Burn abnormal and send " " sound, Moisture high UCL is substandard product; Send " Pi " explosive sound during burning, show the water cut severe overweight of oil, and be likely adulterated product, definitely can not buy.
Five ask: the purchase channel of asking businessman, ask for purchase invoice if desired or check the sampling Detection report of local Food Hygiene Surveillance department.
But these above-mentioned discriminatings are mainly determined by the sense pipe of people, and because the sense organ of people there are differences, therefore, these methods obviously exist not scientific.Difficulty is brought to market surpervision.
Summary of the invention
The object of this invention is to provide a kind of reproducible, a kind of capacitive quick waste oil detection method that detection speed is fast.
The object of the present invention is achieved like this, a kind of capacitive quick waste oil detection method, it is characterized in that: in closure casing Nei You measured oil sensing chamber, measured oil sensing chamber connects a suction pipe by sucking pump, suction pipe is communicated with measured oil sensing chamber by sucking pump, ring casing capacitor plate is had in measured oil sensing chamber, ring casing capacitor plate is electrically connected with testing circuit, when opening sucking pump work by the operating switch on closure casing, suction pipe is aimed at waste oil and is sucked by waste oil on the ring casing capacitor plate of measured oil sensing chamber, then vibrated by Vib., detected oil is evenly distributed on ring casing capacitor plate and forms oily medium, change the capacitance of ring casing electric capacity, this capacitance is compared with the capacitance of the known edible oil detected by the testing circuit in closure casing, testing circuit just can determine whether the new detected oil detected is waste oil.
Testing circuit is had in described closure casing, testing circuit is electrically connected with memory, the standard database that all qualified edible oils that market is sold are set up is had in memory, all qualified edible oils that testing circuit as detected, market is sold can find answer at standard database, otherwise, then do not have answer, result is shown by the display on closure casing.
Advantage of the present invention is: owing to sucking waste oil sensing chamber by being detected oil, ring casing capacitor plate is had in waste oil sensing chamber, vibrated by Vib., waste oil is made to be evenly distributed on ring casing capacitor plate, the data of being stored by the standard oil that the market of storing in capacitance signal and memory is supplied are compared, determine whether it is waste oil, when not identical with the data that standard oil stores or inconsistent time, provide not identical or inconsistent prompting.
Accompanying drawing explanation
Below in conjunction with embodiment accompanying drawing, the invention will be further described:
Fig. 1 is embodiment of the present invention structural representation;
In figure, 1, closure casing; 2, suction pipe; 3, operating switch; 4, measured oil sensing chamber; 5, display; 6, ring casing capacitor plate; 7, Vib.; 8, sucking pump; 9, detected oil; 10, testing circuit; 11, memory.
Embodiment
As shown in Figure 1, a kind of capacitive quick waste oil detection method, in closure casing 1 Nei You measured oil sensing chamber 4, measured oil sensing chamber 4 connects a suction pipe 2 by sucking pump 8, suction pipe 2 is communicated with measured oil sensing chamber 4 by sucking pump 8, ring casing capacitor plate 6 is had in measured oil sensing chamber 4, ring casing capacitor plate 6 is electrically connected with testing circuit 10, when the operating switch 3 pressed on closure casing 1, open sucking pump 8 when working, suction pipe 2 is aimed at waste oil and is sucked by waste oil on the ring casing capacitor plate 6 of measured oil sensing chamber 4, then vibrated by Vib. 7, detected oil 9 is evenly distributed on ring casing capacitor plate 6 and forms oily medium, change the capacitance of ring casing electric capacity, this capacitance is compared with the capacitance of the known edible oil detected by the testing circuit 10 in closure casing 1, testing circuit 10 just can determine whether detected oily 9 of new detection is waste oils.
The known edible oil detected by the testing circuit 10 in closure casing 1 leaves in memory 11, the standard database that all qualified edible oils that market is sold are set up is had in memory 11, testing circuit 10 is as detected that all qualified edible oils that market is sold can find answer at standard database, otherwise, then do not have answer, result is shown by the display 5 on closure casing 1.
