Culture medium preparation machine using pushed circling-motion oscillation and heat homogenization

Abstract

The invention discloses a culture medium preparation machine using pushed circling-motion oscillation and heat homogenization. The culture medium preparation machine comprises a machine body, a homogeneous oscillation heat-expansion device, outer end connection holes, a sealing cover, a control panel and an observation port. The culture medium preparation machine of the present invention has beneficial effects as follows: the culture medium preparation machine utilizes an improved test tube holder that is fixed by a movable chain rod and an arc-shaped plate, so that an upper part and a lower part of a test tube do a movable motion to realize mixing and stirring for lower liquid under the action of back-and-forth impact, thereby avoiding incompatibility of stock solution in the lower liquid, the height difference between an isolation plate and the test tube as well as round holes in the surface of the isolation plate can be used to achieve the airflow at the bottom of the test tube, thereby avoiding that the accumulated bottom heat is difficult to dissipate after heat treatment, resulting in a local temperature difference in the culture medium, and a heat homogenization structure isused to uniformly heat a culture medium solution in the test tube in order to prevent microorganisms from being destroyed in the culture medium solution, resulting in unavailability of the culture medium solution in normal conditions.

Description

technical field [0001] The invention relates to the field of microbial culture medium production, more precisely, it relates to a culture medium preparation machine which utilizes push and push circular motion to oscillate and heat evenly. Background technique [0002] For the development of industry, agriculture, medicine, animal husbandry and veterinary medicine, the cultivation of microorganisms has a huge effect on them, especially in the emergence of modern biotechnology, which shows the contribution and wealth that microorganisms will make to human beings. It is incalculable, so in the process of producing and cultivating microorganisms, because they need to survive in a specific living environment, it is necessary to make their culture medium at different times, and it is necessary to use a culture medium preparation machine to cultivate different microorganisms However, when the culture medium is heated and stirred, the traditional culture medium making machine moves...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a culture medium preparation machine that utilizes pushing circular motion to oscillate and heat uniformly, so as to solve the problem of the prior art that the traditional cultivation method is difficult when the medium is heated and stirred. The base making machine moves in a circular motion to stir the culture solution in the test tube. At the same time, when the test tube moves in a circular motion on the chassis, the upper part is impacted and shaken by a large centrifugal rotation, and the liquid in the lower part exists. There is a phenomenon of incompatibility of the original solution, and there is no phenomenon of shaking and stirring. At the same time, during the heating treatment of the medium and the cooling treatment after heating, at the same time, the heat at the bottom of the medium is large and It is not easy to dissipate heat, which leads to the defect of local temperature difference phenomenon in heating treatment and cooling treatment
