step two, the buckle (11) is separated from the detection box (1), then the box cover (9) is turned over, the detection cover (4) is opened after the detection cover is turned over, the limit block (302) is pulled, the limit block (302) drives the limit rod (36) to move towards the direction of being separated from the groove wheel (35) through the connecting rope (39), the spring (38) is pressed, when the limit rod (36) is separated from the groove wheel (35), the test paper (33) can be pulled, the test paper (33) drives the paper roller (32) to rotate, the test paper (33) can be pulled out, after the test paper is pulled out, the limit block (302) is loosened, the spring (38) resets, the spring (38) can drive the limit rod (36) to slide into the inside of the groove wheel (35) through elasticity to limit the paper roller (32), then the test paper (33) is placed into the limit rail (304), then the mixed liquid is dripped on the test paper (33), and the test paper (33) is folded, the detection cover (4) is covered on the tester (2) to achieve the purpose of stopping the food interior Detecting pesticide and veterinary drug residues in the department;
step three: the limiting piece (85) is pushed to the inside of the driving seat (84), the culture dish (82) can be taken out after the limiting piece (85) is separated from the culture dish (82), then the mixed liquid is dripped into the culture dish (82), the loading frame (64) is taken out, the clamping block (68) is stirred to enable the elastic sheet (69) to be compressed, the culture dish (82) is placed on the loading plate (67) and the clamping block (68) is loosened, the elastic sheet (69) resets, the elastic sheet (69) drives the clamping block (68) and the culture dish (82) to limit through elastic force, then the loading frame (64) is placed on the magnet block (63), the electric heating pipe (65) and the speed reducing motor (61) are started simultaneously, the electric heating pipe (65) can transfer heat to the culture dish (82) through the heat conduction cover (66), and in the process of heating the culture dish (82), the speed reducing motor (61) can drive the culture dish (82) in the loading frame (64) to rotate through the clamping plate (62), thereby, the culture dish (82) can be heated uniformly, and the strains in the mixed liquid can be fully heated to grow.
Step four: after the test paper (33) is heated for a certain time, the contrast card is taken out, the color of the contrast test paper (33) is compared with the residual concentration on the test card, and after the flora culture in the culture dish (82) is finished, the flora can be observed through a microscope.
