The complete equipment comprises a detection box and detection equipment arranged inside the detection box, wherein the detection box comprises a double-layer box body and a box cover which is movably connected with the double-layer box body; the detection equipment comprises sample pretreatment equipment, rapid colloidal gold detection cards, an experiment reagent, reading and data processing equipment and experiment materials; the rapid colloidal gold detection cards comprise an aflatoxin B1 detection card, an ochratoxin A detection card, a zearalenone detection card and a vomitoxin detection card. According to the complete equipment, all equipment, reagents and materials required in safety detection on cereal feed are subjected to integrated innovation and are integrally combined, the effect of a mobile laboratory is achieved, and the complete equipment is applicable to on-site rapid detection on the grain cereal safety, so that the purpose that harmful substances can be discovered, monitored and managed in time is achieved; moreover, the complete equipment is convenient to carry and has the function of knock resistance and drop resistance.

Description

technical field [0001] The invention relates to a detection device for detecting the safety of grains and grains, in particular to a complete set of equipment capable of quickly detecting the safety of grains and grains on the spot, which integrates sample preprocessing equipment, detection reagents, detection cards, consumables, data reading and data processing The equipment is integrated, suitable for on-site rapid screening of grain safety. Background technique [0002] At present, mycotoxin contamination has become one of the important food safety issues. Mycotoxins widely pollute crops and their products. According to estimates by the Food and Agriculture Organization of the United Nations, about 25% of agricultural products in the world are polluted by mycotoxins every year, and 2% of grains lose their nutritional and economic value due to serious pollution, causing tens of billions of dollars in losses. Economic losses. The conventional mycotoxin analysis method has...
