Edible vegetable oil and fat smoke point automatic analyzer

Abstract

The invention involves a kind of edible plant grease smoke to order an automatic measurement instrument. Measuring the instrument establishes a smoke examination box, examination box from box body, light source, lens, light column, the light detector, cigarette holder, light trap, gasp device to constitute; The ray of light source radiation is through the lens also focuses through a light column in the cigarette holder above, the smoke spreads to shoot output light signal to pass light the column focuses through the lens at light detector up; Be examining light road anti- to extension on-line establish light trap; Cigarette holder just above in order to gasp device, cigarette holder with gather a smoke cover to connect with each other, under one by one in order is sample cup, heating apparatus, the temperature spreads a feeling machine to place in sample cup, is carried out smoke by the single slice machine to order an automatic measurement. Its advantage BE: Light source and light detector aren't on a straight line, adopting light trap in the meantime, raising an examination of intelligent degree and accuracy; The pollution established to shield to lead to flow bore, gasped device and lined up dirty bore, avoided soot to give or get an electric shock a component to the light, let up temperature to the influence which gives or gets an electric shock a component only, raised instrument accuracy and service life.

Description

technical field [0001] The invention relates to an instrument for measuring the smoke point of oil. In particular, the utility model relates to an automatic smoke point detector for edible vegetable oils and fats that can automatically measure the smoke point during the heating process of edible vegetable oils. Background technique [0002] The smoke point of oil refers to the lowest temperature at which thermal decomposition products or impurities can be seen by the naked eye when the oil is heated, and it is one of the indicators to measure the thermal stability of the oil when it is heated. The smoke point of oil is regarded as one of the important quality indicators of first-class oil in the quality standard of edible vegetable oil in my country. At present, my country's oil smoke point measurement equipment is quite backward, and the oil temperature is still controlled manually, the oil fume is observed by human eyes, and the oil temperature is read by a thermometer. ...

AI Technical Summary

Problems solved by technology

The following problems will exist in the implementation of this technology: ① Different varieties and different qualities of edible vegetable oils produce different amounts of pyrolysis substances during the heating process, and the smoke concentration will be different, and their shading and absorption degrees are different, making it difficult to determine the smoke point

②In the detection and sensing device, the photoelectric element is located in the smoke pipe. Although there are air extraction devices and anti-pollution holes, it can only reduce and cannot eliminate the pollution of the photoelectric element by grease smoke, and cannot eliminate the pollution of the smoke pipe. When the photoelectric After the components and the smoke pipe are polluted, the detected signal must be inaccurate

③The photoelectric element is in the smoke pipe, as the grease heats up, the temperature of the photoelectric element also rises, and the performance parameters change, which will affect the detection
