The invention relates to a device and a method for quickly detecting residual banned drugs in seafood products on site. The device comprises a control box and a sniffing cylinder, a signal acquisition, processing, identification and judgment instrument, a display PLC (Programmable Logic Controller) and a lithium battery are arranged in the control box; a lower protective net is fixed in the sniffing cylinder, a monitoring camera is installed on the bottom face of the lower protective net, air inlet holes are formed in the peripheral wall of the sniffing cylinder, a lower fixing rod and an upper fixing rod are fixed in the sniffing cylinder, and an electronic nose gas sensor array is installed on the lower fixing rod. A servo motor connected with the capacitive proximity switch is mounted on the upper fixing rod, and suction fan blades are mounted on a rotating shaft of the servo motor; the sniffing cylinder is connected with a connecting rod, the capacitive proximity switch and the monitoring camera are electrically connected with the display PLC, and the electronic nose gas-sensitive sensor array is electrically connected with the signal acquisition, processing, identification and judgment instrument. Only one detector is needed to perform field detection on the seafood product to judge whether the seafood product contains the residual prohibited drugs, so that the detection quality and efficiency are improved.
Description
technical field [0001] The invention relates to the technical field of food safety detection devices, in particular to a device and method for quickly detecting residual prohibited drugs in seafood products on site. Background technique [0002] Chloramphenicol and its salts, lipids and preparations, nitrofuran compounds, various mercury preparations, various insecticides such as malachite green, growth-promoting hormones, etc. are banned drugs in the aquatic industry. [0003] Among the prohibited drugs, malachite green, which has both antibacterial and insecticidal functions, is the most commonly used. Malachite green is also known as basic green, strict block green, and malachite green. It is a synthetic triarylmethane chemical substance. A dye, soluble in water and ethanol, is a dark green crystalline solid, named for its malachite green appearance. Because malachite green is very effective in killing fish internal and external parasites and molds in fish eggs, and is v...
