The invention provides a bacterial colony counting device, and belongs to the technical field of microorganism detecting equipment. The bacterial colony counting device comprises a sunshade hood, a light source assembly, a culture medium bracket and a photosensitive assembly, wherein a cavity is formed in the sunshade hood and is used for isolating external light rays; the light source assembly isarranged at the upper part of the inner part of the sunshade hood, and is used for emitting parallel light downwards; the culture medium bracket is arranged at the middle part of the sunshade hood, and is used for allowing culture mediums to be placed; and the photosensitive assembly is arranged at the lower part of the inner part of the sunshade hood, and is used for receiving light penetratingthrough the culture mediums. According to the bacterial colony counting device disclosed by the invention, through cooperation of the sunshade hood, the light source assembly, the culture medium bracket and the photosensitive assembly, images before and after culturing in the culture mediums are obtained for comparison, the situation that operators are in direct contact with the culture mediums isavoided, and damage of harmful bacterial colonies to human bodies is avoided; and original counting data can be copied, and can be checked for a long term.
Description
technical field [0001] The invention belongs to the technical field of microorganism detection equipment, and more specifically relates to a colony counting device. Background technique [0002] Microbiological testing is an important part of food safety testing. For the microbial content in some tested objects, it is usually detected by counting the colonies in the medium after culture medium. The existing colony counting method mainly uses artificial identification and counting of colonies, but this method has certain requirements on the level of counting people, which is labor-intensive and inefficient, and some harmful flora may be harmful to human health. At the same time, manual counting is used, and the original data of the colony is difficult to retain and cannot be reviewed, so the test results are greatly affected by artificial factors. Contents of the invention [0003] The purpose of the present invention is to provide a colony counting device to solve the tec...
