Medical waste autoclave core technology uses high-temperature steam sterilization for waste processing, i.e., moist heat sterilization. Using high-temperature saturated steam as the working medium, it utilizes its strong penetrating power to penetrate deeply into the sterilized goods and release the latent heat contained in the steam. This causes the sterilized goods to warm up rapidly to the sterilization temperature, which is then maintained for a period of time, causing the protein in the bacteria to coagulate and denature, thus killing all microorganisms including bacterial spores.
Steam sterilization works by using the latent heat released by steam at a certain pressure. Factors such as the internal temperature of the waste, steam penetration, and processing time can ultimately affect the sterilization effect. Steam sterilization is usually most effective when it has sufficient penetration of crushed medical waste at a certain pressure and when the temperature at the center of the loaded waste reaches 134°C.
Steam sterilization consists of two methods: 1) steam sterilization followed by shredding, and 2) shredding followed by steam sterilization.
Sterilization followed by shredding involves first placing medical waste into a special pressure vessel, then subjecting it to vacuum, high-temperature, high-pressure steam sterilization treatment. The treated waste meets the required safety standards for discharge and is then completely destroyed and shredded by a special shredder.
Shredding followed by sterilization involves first placing chemically disinfected medical waste into a sealed chamber equipped with a crusher to dismantle the medical waste. The crushed waste residue is then sent into the sterilization chamber. After vacuum autoclaving in the sterilization chamber, the waste is compressed and transported to a sanitary landfill.
Crushing followed by sterilization is a complex and costly method, so the prior art often uses sterilization followed by crushing. The shortcomings of sterilization followed by crushing are:
- the sterilization effect is not good, especially when there is a large amount of medical waste, as it is difficult for steam to penetrate all the medical waste;
- the sterilization process causes clumping, which affects subsequent discharge, transportation, and the crushing process.
Medical Waste Autoclave Features:
Low noise, low energy consumption, large processing volume, no pollution emission, no soot or any gas produced during processing.
Waste gas, wastewater, and other bacteria-containing emissions produced during the sterilization process are discharged after sterilization treatment.
The sterilization treatment method is not affected by the composition of the waste, and the sterilization effect will not be affected by the high or low calorific value of the waste.
