How Does Pharma Oven Work?

The working principle of a pharmaceutical oven depends on the principle of convection.

The process goes through the following steps:

Working of pharma oven

Working of pharma oven

  • Step One: Preparation Stage

Place the materials that you intend to work on in the oven chamber.

Ensure that the machine is in proper working condition before programming it accordingly from the control panel.

After that, you will switch on the oven and allow it to proceed with the drying process.

  • Step Two: Actual Drying Process

The element will heat the air within the heating chamber and the air blower rotates to spread the hot air.

As the hot air flows to the oven chamber, it displaces the cold air which goes back to the heating chamber.

The process continues until the chamber is warm thus causing uniform drying as air moves over and under the trays.

The temperature within each oven has fair distribution thus causing an even drying process.

As it eliminates the excess moisture, the oven maintains the relative humidity which does not affect the drying process.

  • Step Three: Final processes

After the completion of the drying process, the oven will stop automatically at the right time.

This is in accordance with the control parameters that you set at the beginning of the drying process.

Allow the materials to cool after removing them from the pharma oven.

What is Hot Air Oven?

Hot air oven is an electrical device that depends on hot dry air to sterilize pharmaceutical materials.

They have thermostats within the device that assist in controlling the sterilizing temperatures.

Which Material is Pharmaceutical Oven Made Of?

Stainless steel is the main material that manufacturers use in making pharmaceutical ovens.

It may have other insulation materials such as rubber to prevent heat from leaking to the outside.

The materials have to undergo FDA approval to ensure they are sufficient and stable for a pharma oven.

Stainless steel is the better option because it is easy to clean, has high tensile strength and is readily available.

What are Sterilizing Oven?

Sterilizing ovens depend on hot air within the oven to sterilize and kill pathogens on pharmaceutical products.

They are critical machines that you can use in medical, biotechnology and other sensitive industries.

You can use it to sterilize stainless steel equipment and glass ware.

What is Oven Drying?

Oven drying is the process of eliminating excess moisture from a product through evaporation.

Drying ovens use the principle of convection heating where the oven heats the object through air currents.

What is Vacuum Drying Oven?

Vacuum drying oven is a machine that you can use in delicate drying processes.

The delicate processes include removing flammable products from different products and drying of tiny parts.

It works in a low pressure environment which reduces oxidation during the drying process.

Standard vacuum ovens can operate ate temperatures ranging between 200 to 250 degrees centigrade.

How do Sterilization and Depyrogenation Oven Compare?

Sterilization ovens depends on the high temperature within the ovens to effectively kill pathogens on the pharmaceutical products.

In most cases, you will use a sterilization oven to destroy pathogens on solid pharmaceutical products.

Depyrogenation, on the other hand, refers to the extraction of pyrogens from pharmaceutical solutions such as injectable pharmaceuticals.

A depyrogenation oven uses heat to destroy pyrogens in pharmaceutical solutions.

Most pyrogens are thermally stable but an efficient depyrogenation oven sufficiently heats and destroys pyrogens under consistent high temperatures.

Both processes depend on hot dry air to remove excess moisture from the products but the type of product varies.

How Does Pharma Oven Compare to Fluid Bed Dryer?

Fluid bed dryers depend on the principle of fluidization to produce an effective granulation and drying system.

During the drying process, fluid bed dryers use hot air flowing at very high speeds to remove excess moisture.

The hot air does not remain within the machine but goes out through the outlet.

The drying process takes place as the products that you need to dry suspend in the air.

On the other hand, pharma ovens get rid of excess moisture from the materials without suspending the materials in the air.

It also uses hot air to dry the materials even though it recycles the hot air and the air travels at a lower velocity.

Which Parameters Affect Efficiency of Pharma Ovens?

There are significant factors that you need to consider as they will determine the efficiency of the pharma ovens.

Whenever you are looking for a good pharma oven, you need to look at the following parameters:

  • Safety

Safety is paramount and you should go for a safety mechanism that is advanced with auto shut-off systems and alarms.

The system should also protect you from over temperature and excess heating.

  • Mode of Operation

You should consider having an automatic operating system with a user friendly interface that you can easily maneuver.

It should have data logging capabilities or process parameter recorders especially if you will be using it in a laboratory.

  • Operation Efficiency

A pharma oven that has high levels of drying, precision, accuracy and consistency is the best choice for you.

To have an effective and efficient operation efficiency you need to consider the following factors:

i. A machine with the capability of monitoring temperature precisely

ii. A wide temperature heating range

iii. An efficient heating mechanism

iv. An electric motor that does not consume a lot of energy during the drying process.

v. A gasket that is FDA approved and a structure of stainless steel

vi. An oven that is easy to maintain and clean

vii. Time it takes for a particular type of oven to dry the products effectively.

Apart from that, you need to consider the type of product that you intend to dry.

The type of product will also affect the choice of machine in the following ways:

  • Sensitivity of Products

Your choice of drying oven will depend on the sensitivity of the material you intend to dry.

For instance, very sensitive materials will require you to use a vacuum drying oven.

  • Moisture Content

The level of moisture within a product determines the type of oven you will use.

Products with high moisture levels will require an oven with wide temperature ranges.

This will also affect the time it takes to dry the products effectively.

  • Type of Material

Products have different materials which require different drying temperature ranges.

Consider a pharma oven that can handle a wide range of materials under different temperature ranges.

What is the Heat Source for Pharma Oven?

Pharma ovens have different heat sources depending on the type and design of the pharma oven.

The main heat sources include electricity, vapor, or infrared heat.

Why Should Hot Air Oven Recycle Hot Air?

Hot air ovens recycle hot air inside the oven to enhance the conduction of heat within the oven thus increasing the efficiency.

Apart from that, hot air ovens are energy efficient and recycle hot air to save the resources of energy.

Does SaintyCo has Custom Pharmaceutical Oven?

Yes, SaintyCo has custom pharmaceutical ovens.

You can come up with a custom design that will go through an assessment with a team of design engineers.

After approval, SaintyCo will go ahead and manufacture the custom pharmaceutical oven.

How Does Pharma Oven Compare to Freeze Dryer?

A freeze dryer depends on a water removal process in the preservation of perishable materials thus extending the shelf life.

It freezes the materials and reduces the pressure while adding more heat to allow sublimation of the material.

Pharma ovens, on the other hand, depend on heat to remove the excess moisture from the pharmaceutical materials.

The process involves heating hot air and then spreading it within the oven to eliminate excess moisture.

What is the Working Temperature for Pharma Ovens?

Pharma ovens have varying working temperatures depending on the type of oven.

For instance:

You can have a special purpose oven with a maximum temperature of 500 degrees Fahrenheit for an electric unit.

The same pharma oven may have a maximum temperature of 194 degree Fahrenheit for a steam unit.

Implying that, the working temperature will depend on the source of heat and the product you intend to dry.
