Ultrasonic aflatoxin extraction device

Abstract

An ultrasonic aflatoxin extraction device for rapid and direct detection of aflatoxin in grains. It consists of an ultrasonic power supply, a vibrator, a door, a lifting adjustment button, a bracket, a processing time setting key, a processing power setting key and a power switch key. The ultrasonic power supply is installed in the circuit room on the left side of the device; the vibrator structure is fastened on the top of the device with its rear seat. There is an adjustable lifting bracket assembled on the bottom plate in the processing chamber; the lifting adjustment button for adjusting the lifting of the bracket and realizing positioning is assembled on the lower part of the right side wall. The front wall of the circuit room of the device is equipped with a processing time setting key, a processing power setting key and a power switch key. The door is a hollow double-layer flat structure made of transparent PC material. The right side wall, top and left side wall of the processing chamber, that is, the right side wall and the bottom of the circuit room are all hollow double-layer flat plates made of PC material, and the upper and lower four parallel flutes are consolidated into a frame structure; Fastened and matched with screws, the frame structure forms a slot structure with the back plate of the processing chamber.

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,...

AI Technical Summary

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
