The invention relates to an edible oil smoke point accurate measuring device, and effectively solves the problems that edible oil smoke point detection is easy to lower, and a sensor is influenced byoil stain and temperature, and the detection precision is reduced. According to the device, the device comprises a heating base, a cover body is arranged on the base, a smoke hole is formed in the topof the cover body; a vertical circular pipe is arranged on one side of the cover body; a communicating pipe is connected between the cover body and the circular pipe; a gap is formed between one endof the communicating pipe on the cover body and the top of the cover body and is higher than the other end of the communicating pipe; two radial glass tubes are installed on the side wall of the roundtube, a light source is installed in one glass tube, a photoelectric sensor is installed in the other glass tube, a cleaning device is installed in the round tube, and the cleaning device can wipe and clean the inner end faces of the glass tubes. According to the device, the influence of discontinuous micro smoke before a smoke point can be filtered, the low smoke point measurement value can be avoided, and the influence of oil stain and high temperature on the photoelectric sensor can be avoided.
Description
technical field [0001] The invention relates to the field of food detection, in particular to an accurate measurement device for the smoke point of cooking oil. Background technique [0002] The smoke point is an important indicator of edible oil, which refers to the temperature at which the edible oil starts to smoke continuously and steadily; when detecting the smoke point of edible oil, there are generally two methods: visual observation and sensor detection. It has been gradually replaced; cooking oil often produces one or several puffs of smoke before it reaches the smoke point of continuous and stable smoke. The use of sensor detection equipment will detect these puffs and misjudge the smoke point, so that the measurement The smoke point is lower than the actual one; in addition, with the use of the equipment, the sensor is smoked and baked by oil, and the oil and oil stains will reduce the detection accuracy, and the high temperature during detection will also affect ...
