[0002] The residual solvent detection device for edible vegetable oil is a device used to detect harmful chemical solvents remaining in edible vegetable oil. In the process of extracting and processing vegetable oil, some organic solvents, such as n-hexane and ether, are often used to extract oil. However, if these organic solvents remain in the final edible oil, they may cause harm to human health. Therefore, a detection device is needed to ensure the quality and safety of edible oil.

The detection signal processing module is used to process the current detection signal generated by the FID detector, including a differential operational amplifier noise reduction processing circuit and an amplitude stabilization adjustment circuit. The utility model processes the current detection signal output by the FID detector through the detection signal processing module, effectively suppresses common-mode interference by using the differential amplification principle, and effectively prevents the influence of environmental interference factors during the amplification process of the current detection signal, thereby ensuring the accuracy of the current detection signal amplification. The output signal of the differential operational amplifier is further stabilized by using the amplitude stabilization adjustment circuit, so that the current detection signal has good stability, ensuring that the MCU unit receives the current signal accurately and effectively, thereby improving the accuracy of the edible vegetable oil residual solvent determination result.
