Fuente: WIPO "industrial hemp" The invention relates to the technical field of harmful substance treatment, in particular to a separation and detection system for THC harmful substances in industrial hemp. The system involves a crushing cylinder, a feeding box, a residue filtering cylinder, a soaking cylinder, a rotary cylinder, a separation box and a detection box. According to the separation and detection system for the THC harmful substances in the industrial hemp, through multiple integrated arrangements, the industrial hemp can be pre-treated and then enter the separation box to be separated, so that separation is more thorough, the harmful substances can be completely treated, the industrial hemp is subjected to multiple sampling through the detection box on the right side, and the problems that existing separation equipment for the THC harmful substances in the industrial hemp is simple in arrangement, the industrial hemp needs to be crushed and squeezed by an operator in advance and then enters a separator to be separated, traditional detection equipment for separating the THC harmful substances in the industrial hemp is inconvenient for sampling, only the hemp on the surface of a sample disc is sampled, and an average value cannot be evaluated are solved.
