Ultrasonic aflatoxin extraction device

Abstract

The invention discloses an ultrasonic aflatoxin extraction device for quickly and directly detecting aflatoxin in cereals. The ultrasonic aflatoxin extraction device consists of an ultrasonic power supply, a vibrator, a door, a lifting adjustment button, a support frame, a treatment time setting key, a treatment power setting key and a power switch key, wherein the ultrasonic power supply is arranged in a circuit chamber on the left side of the device; the vibrator structure is assembled at the top of the device in a fastening manner through a rear seat of the vibrator structure; the support frame capable of adjusting lifting in a treatment chamber is assembled on a base plate; the lifting adjustment button for adjusting the lifting of the support frame and achieving positioning is assembled at the lower part of the right side wall; the treatment time setting key, the treatment power setting key and the power switch key are assembled on the front wall of the circuit chamber of the device; the door is in a hollow double-layer flat-plate structure made of a transparent PC material; the right side wall plate, the top and the left side wall plate of the treatment chamber, namely the right side wall plate and the base plate of the circuit chamber, adopt hollow double-layer flat plates made of PC materials, and are fixedly connected through upper and lower four parallel edges to form a frame structure; due to fastening fit of clamps and screws, the frame structure and a rear back plate of the treatment chamber form a slot structure.

Description

technical field [0001] The invention relates to a food toxin detection device. Background technique [0002] As my country's food safety issues have been paid more and more attention, food safety inspection, especially the inspection of harmful ingredients has also been paid more and more attention. Among them, the detection method of food toxins has also become a topic of widespread concern. The existing food toxin detection method is: first prepare the extract, such as 8:2 methanol + pure water mixture, and then fully and evenly pulverize the sample such as corn; then, mix and stir the extract and the sample in a certain proportion , so that the extract and the sample are mixed fully and evenly; then, the mixed slurry is vibrated in a vibrator for a long time (such as above 10); then, it is centrifuged and settled for a certain period of time, and then an appropriate amount of vibration is taken out. Add the solution to the kit ("microwell") by pipetting the supernatant,...

Problems solved by technology

First of all, the processing and treatment of the sample make the sample beyond recognition, which makes the detection process and results doubtful due to the shape change of the sample, and even loses the persuasiveness of physical evidence; Processing, as well as the cumbersome process required for the preparation of the extract, expensive material costs, etc., make the detection process not suitable for on-site evidence collection, and cannot be quickly detected, thus losing the timeliness of evidence collection
