Microbial culture medium sterilizing machine and method

Abstract

The invention discloses a microbial culture medium sterilizing machine and method, the sterilizing machine structurally comprises a downward pressing rod, a positioning frame, a sealing cover, a machine box, a rotating shaft and a culture bottle, the rotating shaft is fixed to the machine box, the machine box is movably connected to the sealing cover through the arranged rotating shaft, the positioning frame is of an arc-shaped structure and located at the upper end of the sealing cover, and the positioning frame is matched with the sealing cover by the downward pressing rod penetrating vertically through the center. Through the combined action of an arc-shaped covered edge and a clamping rod, the clamping firmness can be guaranteed through close contact of the clamping rod and the culture bottle, and meanwhile, the clamping rod is tightly contacted with the culture bottle, so that steam water drops on the vertical surface of a bottle body can be scraped off when the culture bottle is taken out; and the arc-shaped covered edge is matched a the attaching rotary table, the culture bottle with the round bottom is scraped off by the tip end of the inclined face of the arc-shaped covered edge when the culture bottle is taken out, so that water in the bottle body of the whole culture bottle is removed more comprehensively and cannot drop in the external environment when the culture bottle is taken out.

Problems solved by technology

[0003] The artificially prepared nutrient matrix suitable for the growth and reproduction of microorganisms or the accumulation of metabolites is called microbial culture medium in microbiology. The sterilization methods of microbial culture medium are divided into dry heat sterilization and pressurized steam sterilization. The steam sterilization method must add a certain amount of water to the sterilizer, put the items wrapped in waterproof paper into it, turn on the power supply, and heat and sterilize. Although the waterproof paper can prevent the items from being soaked by hot water , but there will be a lot of water droplets attached to the outer surface of the waterproof paper. When taking it out, it needs to be shaken in the sterilizer to shake out the water droplets. However, due to high-temperature sterilization, the sterilizer contains a certain amount of heat, and it is easy to be scalded by high temperature. If you take it out without throwing out the water drops, it will soak the sterilizer case and the working environment, and you will easily slip and fall if you are not careful
