6. How Does a Hot Air Circulation Pharmaceutical Oven Work?
How hot air circulation oven works
You will successfully operate a hot air circulation pharmaceutical oven if you understand the working principles.
The pharmaceutical oven depends on the principle of convection to assist in the elimination of excess moisture.
Here is a step by step guide on how a hot air circulation pharmaceutical oven works.
Step One Preparation of the Machine and Products
First, you have to make sure that the pharma oven you are using is in proper working condition.
Apart from that, you should also have the materials that you intend to dry on standby.
Power on the machine and insert the products you intend to dry in the oven chamber.
Program the machine from the control panel by configuring the key drying parameters such as time and temperature.
Step Two: Actual Drying Process
Air will flow through the inlet and into the heating camber.
Once inside the heating chamber, the heating element will heat the air and then the hot air will rise.
At the same time, the air blower will rotate and distribute the air sufficiently within the heating chamber.
Circulation of air involves hot air rising and flowing to the oven chamber to displace cool air back for heating.
The process continues until the whole chamber heats up with hot air.
As the air blows under and over the drying trays, it takes with it, excess moisture from the materials you intend to dry.
There is fair distribution of hot air within the ovens thus leading to a uniform drying process of the pharma products.
The humid air with the excess moisture will flow out through the outlet of the hot air circulation pharmaceutical oven.
Step Three: Final Process
Finally, after the whole process, the pharma oven will automatically stop after the drying time runs out.
Remove the materials from the oven and allow them to cool down.
7. Which is the Best Material for Making a Hot Air Circulation Pharmaceutical Oven?

9. How Does Oven Drying Compare to Vacuum Drying?
Oven drying depends on evaporation working principles to get rid of excess moisture from different pharmaceutical products.
It depends on convection heating where the oven will heat the products using hot air current.
On the other hand, vacuum drying is a process that you can use to dry delicate products.
This involves the removal of excess moisture from flammable products as well as tiny parts of different pharmaceutical products.
A vacuum oven will operate ate different temperatures ranging between 200 to 250 degrees centigrade.
10. How Does Depyrogenation Oven Compare to Sterilization
6 Depyrogenation Oven
Sterilization ovens depend on the increasing temperature levels within the oven chamber to get destroy pathogens.
In many cases, you will destroy pathogens on solid pharmaceutical products using the sterilization oven.
On the other hand, you will use a depyrogenation oven to extract pyrogens from different pharmaceutical solutions such as injectable pharmaceuticals.
It uses hot air currents within the oven chambers to destroy and kill pyrogens in pharmaceutical solutions.
Most pyrogens are usually thermally stable but through a consistent rise in temperature, the oven eliminates the pyrogens completely.
Both the depyrogenation oven as well as the sterilization oven depends on hot air circulation to destroy the impurities.
11. What are the main Quality Regulation Standards of Hot Air Circulation Pharmaceutical Oven?
You have to look at the different types of quality standards on a pharma oven when purchasing an oven.
The quality standards are international marks of quality which ensures safety, consistency, reliability and optimal machine performance.

With this knowledge, you will program your machine effectively to boost the efficiency of the pharma oven.
13. How Does Hot Air Circulation Pharmaceutical Oven Compare to Fluid Bed Dryers?
Fluid bed dryers use the fluidization principle in the process if forming granules and eliminating excess moisture.
Hot air flows at very high speeds inside the fluid bed dryer thus taking with it the excess moisture.
In this case, hot air will not remain within the oven chamber but go out through an outlet.
During the drying process, the pharma products that you intend to dry usually suspends in the air.
Pharma ovens, on the other hand, do not release the hot air to the outlet after eliminating the excess moisture.
Apart from that, the air does not move at high speed and the products remain on the trays without suspension.
