Device and method for quickly detecting rice mildewing

Abstract

The invention discloses a device and a method for quickly detecting rice mildewing. The device comprises a data acquisition device and a computer, wherein the data acquisition device comprises a microprocessor, a sample chamber, a gas chamber, a gas-sensitive sensor array and a first gas pump; an upper communication pipe and a lower communication pipe are arranged between the sample chamber and the gas chamber; a gas inlet is formed in the gas chamber; the gas inlet is connected with the first gas pump through a first gas inlet pipeline; a first solenoid valve is arranged on the first gas inlet pipeline; a gas outlet and a second gas pump are arranged on the upper communication pipe; a gas outlet solenoid valve is arranged on the gas outlet; the air-sensitive sensor array is arranged in the gas chamber. According to the method, rice volatilization gas is detected through the gas-sensitive sensor array, the microprocessor is used for sampling response signals generated by gas-sensitive sensors, and the computer is used for processing sampling values, calculating dynamic classification parameters delta through a nonlinear random resonance algorithm and a nonlinear self-calibration dynamic classification model so as to judge if rice is mildewed. The device and the method can be used for quickly and accurately detecting if the rice is mildewed.

Description

technical field [0001] The invention relates to the technical field of food detection, in particular to a device and method for rapid detection of rice mildew. Background technique [0002] Food safety is an important factor affecting human health, and has always been the focus of research by relevant departments around the world. Rice is rich in protein, carbohydrates, fat and other ingredients, and has high nutritional value. However, in the production process of rice, there are various molds such as Aspergillus flavus, Aspergillus parasitica, Aspergillus fusarium, and Aspergillus penicillium, which can easily cause rice mildew under suitable conditions, releasing musty, rotten, rancid and other odors. Nutritious rice has turned into a substance that is poisonous to the human body. At present, it is generally judged whether rice is moldy by artificial senses, but human sensory organs are easily disturbed by the environment, individual differences of judges and subjective...
