Do you know what the vacuum oven is? Have you heard about it before? If yes, then there are a number of businesses that use the vacuum drying oven. Before you know the applications, it is important for you to know what it exactly it is and how does it work? This unit is popularly used in the industrial as well as scientific industries.
What is a vacuum drying oven?
The oven is used to dry heat sensitive materials, particularly at low temperature. The drying time taken here is significantly less when compared to the other drying systems. Nitrogen is fed inside the chamber in order to avoid oxidation. One of the top reasons why businesses are using this kind of oven is because it removes the source of oxidation unlike regular ovens. When metals are heated in the regular oven at a high temperature, then it leads to oxidation and this is something that is not desirable. Thus, in such a situation the vacuum drying oven is useful.
How does the system work?
For drying, the moisture needs to change its form from liquid to gas. He pressures inside the vacuum dying oven decreases and this allows the water to vaporize to gaseous state. The change in the pressure is what makes the moisture to evaporate and so the drying is done at low temperatures. The system includes an airtight vessel and this is the place where drying procedure takes place. Then the vacuum is attracted inside the airtight vessel. The entire drying procedure takes place inside the vacuum.
What are the major functions performed by the vacuum oven at the industrial and scientific sector?
There are a number of functions performed and below mentioned is the list:
- Sterilizing
- Aging
- Brazing
- Soldiering
- Quenching
- Baking
- Curing
- Drying
- Melting
- Heat treating
- Sintering
- Firing
- Preheating
The type of oven is utilized for a number of scientific purposes. The main reason behind this is that it has elements that are suitable for lab purposes. Below listed are the characteristics of the vacuum oven:
- Cooling system
- Carts
- Racks
- Shelves
- Explosion proof construction
- Timer and alarms
There are many products that require vacuum and below mentioned are those:
- Satellites and other space hardware.
- Essential oils extracted from flowers and plants.
- Heat sensitive products that have moisture trapped inside them.
- Packaged foods where the moisture level needs to be examined and extracted.
The vacuum oven has a number of benefits of using in the industrial and scientific industry and following are some important ones:
- Due to low oxygen level, there is no oxidation process.
- Since there is no strong skin on the top, consistent drying is possible which is not possible in the regular ovens.
- The vacuum drying oven even pulls out moisture from the nooks that are tough to reach.
- The drying process is carried on gently without disturbing light or other items
- One of the most important benefits of this unit is that the dangerous gasses and chemicals are not released into the environment but get trapped.
When you are looking out for the vacuum drying oven for your business, there are many types available but below mentioned is the detail of the most commonly used:
Squaroid vacuum oven
This oven can extend the temperature up to 220 C and used for baking, heating, brazing, sterilizing and other purposes.
Multi module vacuum oven
This is the oven that is basically used for a number of packaging applications and helps in temperature curing, laser welding etc.
