Abstract
The invention relates to waste oil detection technology, in particular to a capacitive quick waste oil detection method. The method is characterized in that: a detected oil detection chamber is formed in a closed shell, the detected oil detection chamber is connected with a straw through a suction pump, the straw is communicated with the detected oil detection chamber through the suction pump, an annular chamber capacitor pole plate is arranged in the detected oil detection chamber, and the annular chamber capacitor pole plate is electrically connected with a detection circuit; when a working switch on the closed shell is switched on and the suction pump works, the straw is aligned with the waste oil and sucks the waste oil onto the annular chamber capacitor pole plate of the detected oil detection chamber, then the detected oil is uniformly distributed on the annular chamber capacitor pole plate through vibration of a vibrator to form an oil medium so as to change the capacitance value of an annular chamber capacitor, the capacitance value is compared with the capacitance value of the known edible oil detected through the detection circuit in the closed shell, and the detection circuit can determine whether the newly detected oil is the waste oil. The invention provides the capacitive quick waste oil detection method with good repeatability and high detection speed.
Description
Technical field
The present invention relates to the waste oil detection technique, particularly a kind of condenser type waste oil method for quick.
Background technology
Waste oil is actually the notion of a general reference, is people's common names for all kinds of poor oils in life.Generally, waste oil can be divided into following a few class: the one, the waste oil of narrow sense, be about in the sewer greasy floating thing or with leftovers, the oil of leftovers (common name swill) of hotel, restaurant through simply processing, extracting; The 2nd, pork inferior, haslet, pigskin processing and the oil that refines the back output; The 3rd, after the oily access times that are used for fried food surpass regulation and require, be repeated again to use or toward wherein adding the oil of reusing behind some fresh oils.Many businessmans buy waste oil because it is cheap, and interests are ordered about!
Harm: rubbish oil is quality extreme difference, extremely unhygienic, the unedible oil of peroxide value, acid value, moisture severe overweight.It contains toxin, and flow to rivers and can cause water nutritionization, in case edible, then can destroy white blood cell and alimentary canal mucous membrane, cause food poisoning, in addition carcinogenic.Fried Cargo Oil prolonged and repeated use under the condition of high temperature of one of " rape oil excessively ", contact with airborne oxygen, complex reactions such as hydrolysis, oxidation, polymerization take place, cause oily viscosity to increase, color and luster is deepened, peroxide value raises, and produces the material that some volatile matters and aldehyde, ketone, lactone etc. have penetrating odor, and these materials have carcinogenesis.The toxicity of main harm the thing------aflatoxins in " swill oil " then is 100 times of arsenic.
Existing disclosed waste oil is differentiated generally by seeing, hear, taste, listen, ask that five aspects can differentiate.
At a glance.See transparency, pure vegetable oil is transparence, owing to sneaked into things such as alkali fat, wax, impurity, transparency can descend in process of production; See color and luster, pure oil is colourless, because the pigment in the oil plant is dissolved in the oil, oil just can be with look in process of production; See sediment, its principal ingredient is an impurity.
Two hear.Every kind of oil all has unique separately smell.Can drip one or two oil dripping on palm, both hands close up friction, and adstante febre is carefully heard its smell.The oil that peculiar smell is arranged illustrates that quality has problem, and frowzy is exactly waste oil probably; 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 the oil that peculiar smell is arranged may be " waste oil ".
Four tins: get one or two of the oil of oil reservoir bottom, be coated on the inflammable scraps of paper, light and listen its sound.What burn normal no sound is specification product; Burn undesired and send " " sound, Moisture high UCL is substandard product; Send " Pi " explosive sound during burning, show the water cut severe overweight of oil, and might be adulterated product, definitely can not buy.
Five ask: ask the purchase channel of businessman, ask for purchase invoice in case of necessity or check the sampling Detection report of local Food Hygiene Surveillance department.
Yet above-mentioned these differentiate it mainly is that sense pipe by the people is determined, because of people's sense organ there are differences, therefore, these methods obviously exist not scientific.Bring difficulty to market surpervision.
Summary of the invention
The purpose of this invention is to provide a kind of good reproducibility, the fast a kind of condenser type waste oil method for quick of detection speed.
The object of the present invention is achieved like this, a kind of condenser type waste oil method for quick, it is characterized in that: measured oil sensing chamber is arranged in closure casing, measured oil sensing chamber connects a suction pipe by sucking pump, suction pipe communicates with measured oil sensing chamber by sucking pump, the ring casing capacitor plate is arranged in the measured oil sensing chamber, the ring casing capacitor plate is electrically connected with testing circuit, when opening sucking pump work by the operating switch on the closure casing, suction pipe is aimed at waste oil and waste oil is sucked on the ring casing capacitor plate of measured oil sensing chamber, vibrate by Vib. then, detected oil is evenly distributed on forms oily medium on the ring casing capacitor plate, changed the capacitance of ring casing electric capacity, this capacitance compares with the capacitance of the known edible oil that detects by the testing circuit in the closure casing, and testing circuit just can determine whether the new detected oil that detects is waste oil.
In the described closure casing testing circuit is arranged, testing circuit is electrically connected with memory, the standard database that all qualified edible oil foundation of selling on the market is arranged in the memory, testing circuit can both find answer at standard database as detecting all qualified edible oils of selling on the market, otherwise, then do not have answer, the result shows by the display on the closure casing.
Advantage of the present invention is: because by detected oil is sucked waste oil sensing chamber, the ring casing capacitor plate is arranged in the waste oil sensing chamber, vibrate by Vib., waste oil is evenly distributed on the ring casing capacitor plate, the data of storing by the standard oil of supplying on the market of storing in capacitance signal and the memory compare, determine whether it is waste oil, when when inequality or inconsistent, providing inequality or inconsistent prompting with the data of standard oil storage.
