Problems solved by technology

[0003] The main technical methods used in edible oil quality inspection are: gas chromatography analysis, near-infrared spectral analysis, etc. Using these detection methods requires a specific environment, complex machines, and professional technicians during the detection process. Therefore, the inspection of edible oil The process of quality is particularly complicated
It can be seen that in order to solve the complex problem of edible oil quality inspection in the inspection process, it is urgent to find a new method for inspection of edible oil quality

Abstract

The invention discloses a smoke exhaust ventilator which comprises a processor, at least one total volatile organic compound (TVOC) sensor and at least one temperature sensor, wherein the at least one TVOC sensor and the at least one temperature sensor are respectively connected with the processor; the at least one TVOC sensor is used for detecting the lamp black concentration after the fuming of liquid oil; at least one temperature sensor is used for detecting the temperature of the liquid oil corresponding to the lamp black concentration; the processor is used for comparing the temperature of the liquid oil with a preset temperature threshold value when the lamp black concentration is greater than a preset concentration threshold value, acquiring a comparison result and confirming the preset oil quality information corresponding to the comparison result as the quality information of the liquid oil. The invention also discloses a method for detecting the oil quality.

Description

technical field [0001] The invention relates to a technology for detecting oil quality, in particular to a range hood and a method for detecting oil quality. Background technique [0002] In the current domestic market, edible oil mainly refers to vegetable oil and animal oil. In the process of collection and processing, factors such as collection environment, processing environment and processing technology affect the quality of edible oil, and the quality of edible oil has a great impact on people's health and well-being. Food safety is of great significance, therefore, the detection of edible oil quality is particularly important. [0003] The main technical methods used in edible oil quality inspection are: gas chromatography analysis, near-infrared spectral analysis, etc. Using these detection methods requires a specific environment, complex machines, and professional technicians during the detection process. Therefore, the inspection of edible oil The process of quali...
