Cleaning methods for preparations mainly include the following:
Cleaning: Cleaning is the basic method for cleaning preparation equipment, which removes dirt and residues on the surface of the equipment by mechanical or chemical means. Common cleaning methods include:
Water flushing: Use the impact force of the water flow to flush away the dirt on the surface of the equipment, which is suitable for equipment with a relatively flat surface and high hardness.
High-pressure water gun cleaning: Use a high-pressure water gun to spray high-pressure water flow on the surface of the equipment for cleaning, which is suitable for situations where the dirt on the surface of the equipment is thicker.
Chemical cleaning: Use chemical cleaning agents to dissolve dirt and residues on the surface of the equipment. It is necessary to select a suitable cleaning agent based on the material of the equipment and the nature of the dirt.
Steam sterilization: Steam sterilization is to heat the steam to a certain temperature and pressure inside the equipment to kill microorganisms on the surface and inside the equipment. The following points need to be noted:
Control of temperature and pressure: The temperature and pressure of the steam should be controlled according to the material and performance of the equipment.
Sterilization time: The length of the sterilization time needs to be adjusted according to the size and complexity of the equipment.
Testing the sterilization effect: Perform colony counts or biological indicator tests on sterilized equipment to ensure that the sterilization effect meets the requirements.
Air purification: Since preparation equipment often needs to be operated under sterile conditions, air purification is very important. The main methods include:
Air filtration: Filter microorganisms and particulate matter in the air through air filters to maintain air cleanliness.
Clean bench operation: Place the preparation equipment in the clean bench, and use the clean bench's high-efficiency filtration and laminar clean technology to reduce the contamination of microorganisms and particulate matter in the environment to the equipment.
Equipment disinfection: Equipment disinfection refers to the use of disinfectants to treat the equipment to kill microorganisms on the surface of the equipment. Common equipment disinfection methods include:
Acetaldehyde disinfection: Acetaldehyde has a strong bactericidal effect and can be used for disinfection of the surface of the equipment.
Peracetic acid disinfection: Peracetic acid is a broad-spectrum bactericide that can kill microorganisms on the surface of the equipment at a lower concentration.
