Microorganism colony counting instrument and counting method thereof

Abstract

The invention relates to a microbial colony counting instrument which comprises a sample layer, an amplification layer and a shooting layer which are sequentially arranged from bottom to top, and further comprises a first light shield; the amplification layer comprises a mounting plate, and a plurality of microscope assemblies are arranged on the mounting plate; the shooting layer comprises a shooting camera, a shooting turntable and a rotating assembly; the sample layer comprises a plurality of sample index plates, and a plurality of sample grooves are annularly distributed in the sample index plates; and a second light shield is arranged in the first light shield, and the second light shield is longitudinally and slidably connected to the inner top of the first light shield. By means of the method, batch automatic detection can be conducted after one-time feeding, external light interference is reduced to the minimum through the double light shields, and the peripheral light shields are used for shielding light and serve as supporting brackets of the overall structure; and meanwhile, only one shooting camera is needed, the overall structure is reasonable and compact, the detection efficiency is high, the automation degree is high, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of microbial colony counters, in particular to a microbial colony counter and a counting method thereof. Background technique [0002] The determination of the total number of bacterial colonies is used to judge the degree of bacterial contamination of the atmosphere, water quality and food, and it reflects whether the atmosphere, water quality and food meet the requirements of human use, so as to make an appropriate hygienic evaluation of the tested samples; the total number of bacterial colonies To a certain extent, the amount of water marks the pros and cons of the atmosphere, water quality and food conditions. The colony counter counts the cultured colony samples to make an accurate judgment on the degree of bacterial contamination of the atmosphere, water quality and food. [0003] At present, most of the traditional colony counting instruments on the market adopt the method of feeding and detecting on...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the traditional colony counting instruments on the market adopt the method of feeding and detecting one by one, which is easily affected by external light sources during detection, and the detection efficiency is relatively low.
