What is the working principle of hot air oven?
Hot air ovens use extremely high temperatures over several hours to destroy microorganisms and bacterial spores. The ovens use conduction to sterilize items by heating the outside surfaces of the item, which then absorbs the heat and moves it towards the center of the item.
What is the principle of hot air?
Principle of hot air oven Gravity convection process: Heated air expands and possesses less density than cooled air which rises up and displaces the cooler air (the cooler air descends).
What is the application of hot air oven?
Hot air oven is widely used in the medical industry to sterilize the equipment and other materials that are used in a laboratory. It is used for delivering the heat treatment to the product.
What are the main design components of the hot air oven?
Hot air oven Parts and Functions
- External cabinet: The External cabinet is made of stainless sheets.
- Glass wool insulation: The space between the inner chamber and external cabinet is filled with Glass wool.
- Inner chamber: The inner chamber of the hot air oven is made of Stainless steel.
What are the types of hot air oven?
There are two types of hot air ovens. One is a forced air hot air oven and the other is a static air hot air oven. The forced air hot air oven is more effective than the static air hot air oven. The forced air hot air oven works by heating the oven and using a fan to move the hot air around.
What is SV and PV in hot air?
Maximum operating temperature range of these ovens are 150°C, 200°C and 250°C which is controlled through microprocessor based PID temperature controller. It displays both set value (SV) and process value (PV). With the help of RTD PT100 temperature sensor, it measures the temperature precisely.
What is sterilization?
What is sterilization? Sterilization is a permanent method of birth control. Sterilization procedures for women are called tubal ligation. The procedure for men is called vasectomy.
What is the principle of hot air dry heat sterilization?
Principle of Dry heat sterilization using HOT AIR OVEN Sterilizing by dry heat is accomplished by conduction. The heat is absorbed by the outside surface of the item, then passes towards the centre of the item, layer by layer.
What is incubator principle?
Thermostat. A thermostat is used to set the desired temperature of the incubator. After the desired temperature is reached, the thermostat automatically maintains the incubator at that temperature until the temperature is changed again.
What is PV in HVAC?
HVAC systems directly connected to photovoltaic (PV) power sources are relatively rare right now, but they’ll be growing in numbers. Photovoltaic (PV) electrical power systems are becoming increasingly common in residential and commercial building applications.
What is the working principle of a hot air oven?
Hot Air Oven is an electrical devise that works on Heat convection principle. It consist of electrical heating coil that produces dry heat. In the chamber, the produced dry heat air displaces the cooled air forming heat gradient. The use of fan allows to the uniform distribution of heat.
How does a hot air oven work for sterilization?
The use of heat for sterilization was initiated by Louis Pasteur. Hot Air Oven is an electrical devise that works on Heat convection principle. It consist of electrical heating coil that produces dry heat. In the chamber, the produced dry heat air displaces the cooled air forming heat gradient.
What can a hot air oven be used for?
A hot air oven is used to sterilize equipment and materials used in the medical field. A hot air oven is a type of dry heat sterilization.
How does a static air hot air oven work?
The fan keeps the hot air moving around at a consistent temperature throughout the oven. The static air hot air oven works by using a heating coil at the bottom of the oven. The heat rises throughout the oven and takes a longer time to reach the desired temperature.
