a steam sterilizer

Abstract

The invention discloses a steam sterilizer, which comprises a cylinder body and a cylinder cover. An inner barrel with an open top is arranged in the cylinder body. A solution is arranged in the cylinder body. A heating pipe is arranged in the solution. A steam passage is formed between them, and a barrier ring for opening or closing the steam passage is arranged at the upper end of the inner barrel. The invention has simple structure and convenient operation, can sterilize items, and simultaneously dry the sterilized items, thereby improving the qualified rate of sterilized products.

Description

technical field [0001] The invention relates to a steam sterilizer. Background technique [0002] Pressure steam sterilizer is a rapid and reliable disinfection and sterilization equipment for items using saturated pressure steam. Its advantages are rapid heating, thorough sterilization, safety and reliability, and no need to add additional disinfectants, so it is widely used in medical and health , scientific research, agriculture, food industry and other units and places are currently the main method for sterilizing high temperature resistant items. [0003] Among the pressure steam sterilization equipment, small vertical sterilizers and portable sterilizers that are easy to operate, lightweight, convenient, and relatively cheap can meet the sterilization needs of items with a small load. Therefore, they are used in medical institutions, research It is widely used in laboratories, tissue culture factories, food factories, beauty salons and other places. [0004] However,...

AI Technical Summary

Problems solved by technology

[0004] However, due to their simple structure, traditional vertical pressure steam sterilizers and portable pressure steam sterilizers only use a heating device to heat the water filled in the cylinder to form high-pressure steam in a sealed environment, so as to achieve sterilization. effects, and usually no other additional functions

Therefore, for some vertical sterilizers and portable sterilizers currently on the market, because the water vapor directly evaporates above the inner barrel, the hot and humid air sinks when it is cold, and thus adheres to the surface of the sterilization package and affects the drying effect.

For items that are not sufficiently dried, open liquid channels may form on their surface, allowing microorganisms to pass through the sterilization package and enter the sterilized items, resulting in unqualified sterilization
