Sterilizing Oven

• Several types of pharmaceutical sterilizing ovens are available depending on the application or requirement needed. The following are some common ones:

• Dry Heat Sterilizers

• This type makes use of high temperatures to destroy microorganisms. It usually operates at temperatures within the range of 160°C to 180°C. Although dry heat penetrates slowly through materials but very effective in dealing with heat-stable items such as powders and metal instruments or glasses. It is suitable for substances that can be damaged by moisture or steam.

• Steam Sterilizers (Autoclaves)

• Sterilization using pressurized steam takes place in a steam sterilizer also known as an autoclave that functions at temperatures between 121°C-134°C killing off a wide range of microorganisms including bacteria fungi viruses etc.. Autoclaves are often used for sterilizing liquids, glassware surgical instruments laboratory ware.

• Depyrogenation Ovens

• Depyrogenation ovens have been designed specifically to remove pyrogens which are fever-inducing substances released by certain bacteria. Such ovens use high heat levels typically exceeding 250°C to decompose and remove pyrogens from vials glass and other heat-resistant materials commonly employed in the manufacture of drugs.

• Forced Air Sterilizers

• Sterilization via forced air requires hot air that is moved across by fans for it to be achieved in this type. This technique is highly suitable for sterilizing materials that are sensitive to moisture or pressure, such as oils, powders and heat-sensitive things related to healthcare. Forced air sterilizers have faster cycle times as compared to other methods which make them efficient in mass production.

• The working processes of pharmaceutical sterilizing ovens usually depend on the type of method of sterilization being used. However, they generally follow these basic steps:
• Preparation: When preparing for sterilization, items that are placed inside the chamber must be spaced out well enough to allow some amount of penetration by either heat or steam.
• Heating: The temperature required for sterility is reached after heating the sterilizing chamber. In dry heat, it’s hot air that permeates the whole chamber while steam sterilizers produce steam under pressure.
• Sterilization: Once desired temperatures and pressures have been achieved, then the process of sterility begins. On their surfaces, the organisms get killed or denatured by heat or steam.
• Cooling: Gradually reduce the chamber’s temperature after sterilization to prevent thermal shock on items being sterilized.
• Exhaust: To open the door, any excess steam in a steam steriliser should be vented out first from the chamber.

Unloading: This occurs once there is sufficient cooling down in case of a complete cycle of sterilization and completion; thus all sterile objects come outside from the oven again.

• Pharmaceutical manufacturing firms across various sectors use pharmaceutical sterilizing ovens in many different ways including:
• Manufacturing: These ovens provide an effective means through which equipment containers raw materials etc., can be subjected to extreme conditions before drugs are made thereby avoiding contamination during drug manufacturing
