Auxiliary device for detecting aspergillus flavus

Abstract

The invention relates to the field of food detection, in particular to an auxiliary device for aspergillus flavus detection. The auxiliary device comprises a box body and a weight adjusting mechanism used for measuring the weight of a sample, and the weight adjusting mechanism comprises a fixed plate, a transparent sample box, a sample bin, a bearing ring, a bearing spring, a feed opening, a fixed rod, a transmission plate, a weight adjusting chute and an L-shaped plate. A conveying mechanism is fixedly connected with a fixed plate, a bearing hole is formed in the side wall of the upper portion of the end, away from the conveying mechanism, of the fixed plate, a transparent sample box is placed in the bearing hole, and a sample bin is formed in the side wall of the upper portion of the transparent sample box. According to the invention, the density of objects input by an operator is detected so as to control the discharging speed of the funnel and ensure that the quality of discharged samples once is consistent, sampling is performed for multiple times, the samples with different qualities are obtained for multiple times, and the auxiliary device is beneficial to the experiment efficiency and can reduce the labor intensity of operators at the same time.

Description

technical field [0001] The invention relates to the field of food detection, in particular to an auxiliary device for detection of Aspergillus flavus. Background technique [0002] Aflatoxins are a class of compounds with similar chemical structures, all of which are derivatives of dihydrofuranocoumarins. Aflatoxin is a secondary metabolite mainly produced by Aspergillus flavus. The probability of aflatoxin appearing in food in hot and humid areas is the highest. Aflatoxin is extremely harmful to the human body. The hazard of aflatoxin lies in the Animal liver tissue has a destructive effect, and in severe cases it can lead to liver cancer or even death. Aflatoxin B1 is the most common in naturally contaminated food, and its toxicity and carcinogenicity are also the strongest. [0003] The existing aflatoxin needs to be measured before testing, but the quality of the samples required for different experiments is different, and each time the samples need to be collected manu...

Problems solved by technology

[0003] The existing aflatoxin needs to be measured before testing, but the quality of the samples required for different experiments is different, and each time the samples need to be collected manually before the experiment, the manual measurement speed is slow, and each experiment requires multiple Samples, manual collection requires each sample to be measured separately, which seriously affects the speed of the experiment and increases the labor intensity of the experimenters
