You can dry different materials using the hot air drying oven.
You should also note that the hot air circulation oven does not dry all the materials.
You will not dry pharmaceutical products that are sensitive to heat under the pharma hot air oven.
On that note, some of the products which you can dry using the hot air circulation oven are granules, herbs, powders, and fruit slices.
When looking for a hot air circulation drying oven, you can choose from a wide variety of hot air circulating ovens.
You will find different hot air drying ovens based on varying sizes, working principles, designs, nature of the application, and technology.
Here are the main types of hot air circulation drying ovens that you can choose from:
. Vacuum Shelf Ovens
You will use a vacuum shelf oven for batch processing, especially for batch pharmaceutical equipment.
These vacuum shelf dryers are mainly used for drying heat-sensitive materials
. Clean Process Hot Air Circulation Drying Oven
You can use this hot air circulation drying oven for sterilization of the medical equipment since the temperatures go beyond 260 degrees centigrade.
. Burn-In-Ovens
You can use this oven to produce pharmaceutical electronic products with a maximum temperature of 260 degrees centigrade.
. Depyrogenation and Sterilization Pharma Ovens
You can use this type of pharma oven to dry products that can reach about 536 degrees Fahrenheit.
You also have the freedom of dictating the special features to add to your custom depyrogenation and sterilization oven.
A hot air circulation oven has different parts that it uses to properly dry pharma products.
Here are the main parts of the pharmaceutical hot air circulation oven.
• Heat Source of the Hot Air Circulation Oven
This is the part that produces the source of heat which assists in the drying of different products.
It may opt to choose different sources of heat which include electricity, steam, or infrared sources.
The degree of heat circulation within the hot air circulation oven often depends on the heating element in use.
In case the source of heat is vapor, then the oven can comfortably achieve 50 to 150 degrees centigrade.
Apart from that, in case you are using infrared or an electrical heater, the oven will be able to attain 50 to 300 degrees centigrade.
• Automatic Control System of the Hot Air Circulation Ovens
It will use the automatic control system to control all the functions of the hot air drying oven from one central point.
You can key in all the drying parameters of the pharmaceutical oven depending on your drying specifications.
The key parameters that you should consider include drying time and temperature among other parameters.
• Motor-driven blower of hot air circulation oven
The axial flow blower will blow o push hot air from the different heating elements into the chamber of the oven.
It helps in uniformly circulating the air within the chamber. The fan is the auxiliary part of the hot air drying oven with a power of 0.75kw / set. The materials for manufacturing fans are aluminum alloy or stainless steel.
• Hot Air Circulation Oven Trays
You will place all the pharmaceutical products on the oven tray before pushing them into the hot air oven.
The number of oven trays will vary according to the structure and design of the pharma oven.
Once-shaping pressed baking trays are specially designed auxiliary products for hot air circulation drying ovens. Generally, the baking tray is made with the standard size of 640*460*45mm and it also can be customized according to customers' demands.
• Inlet and Outlet of the Hot Air Circulation Oven
These are the chambers that allow air to flow freely into and out of the hot air circulation oven.
As the air flows in, it brings dry air and exits through the outlet with the excess moisture from the products.
• Safety Accessories of the Hot Air Circulation Oven
Pharma Drying ovens have automatic over-temperatures and shutdown systems which will protect the heating chamber from overheating.
It will protect all the contents in the heating chamber from damage, especially from excess heat and high temperatures.
• Lockable Door of Hot Air Circulation Oven
This is a safety mechanism where the stainless-steel door allows you to open and close the feeding chamber of the drying oven.
It has locks that are often engaged during the drying process thus increasing the safety mechanism.
• Insulation Mechanism of Hot Air Circulation Ovens
The space between the inner chamber and the external cabinet is filled with Glass wool.
This part will help in reducing heat loss through conduction to the immediate external environment.
• Inner and External Chambers of the Hot Air Circulation Oven
The inner and external chamber of the hot air tray dryer is made of Stainless steel.
You will successfully operate a hot air circulation oven if you understand the working principles.
The pharmaceutical hot air tray dryer 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 Products
First, you have to make sure that the pharma hot air 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 chamber passing the high-efficiency air filter.
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 a fair distribution of hot air within the ovens thus leading to a uniform drying process of the pharma products.
The humid air with excess moisture will flow out through the outlet of the hot air circulation oven.
• Step Three: Finished the drying and take out the products
Finally, after the whole process, the pharma hot air tray oven will automatically stop after the drying time runs out.
Remove the materials from the oven and allow them to cool down.
Stainless steel is the best material that you can use to make hot air circulation in a pharmaceutical hot air drying oven. but Hywell Machinery is able to offer hot air circulation air with contact parts to be built in SS304, SS316L, Titanium, Duplex stainless steel, etc.
You can use a hot air circulation pharmaceutical oven for sterilization among other purposes.
You can only use a sterilization oven for killing and eliminating pathogens from different types of pharmaceutical products.
You can also use it in the sterilization of glassware as well as stainless steel.
In both types of ovens, the main drying principle depends on the circulation of hot air in the oven chamber.
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 a 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.
In this case, the type of drying oven that you will choose will determine the working temperature.
Apart from that, you will also set the working temperatures of the ovens depending on the material you intend to dry.
Implying that the source of heat for your hot air drying oven will determine the most suitable working temperature for your device.
