An industrial oven works on the same principle as a domestic oven, only on an industrial scale. It is used for curing, drying and baking different components.
Industrial ovens are of different types, usually categorized according to their function. One of the types of the oven in a preheated oven.
The preheated oven is named so because it is used to treat the merchandise before its finishing.
Today we have many preheating oven manufacturers in the industrial production sector. These are mostly oven manufacturers who make industrial ovens.
How Preheating Oven Works
The principle behind the preheating oven is slightly different from the function of a domestic oven. In a domestic oven, we use the preheating function to bring the internal temperature of an oven to a particular level.
This ensures that when we put the food inside, it starts with an exposure to the high temperature instead of a slow increase.
In industrial preheating, an oven is used to treat an object to a high temperature before a secondary process. The product is heated to a specified temperature before moving on to the next phase of the manufacturing process.
Like most industrial ovens, preheating ovens can also use either heating in batches or a conveyor system. Once the preheating is complete, the product can undergo other treatments like coating, fitting, forming and welding.
Preheating oven manufacturers use different types of fuels for producing heat. This includes electricity, steam or fuels like LPG, fuel oil, natural gas or a mix of fuels. Belts, chains or roller hearths can move the product inside.
Preheating Oven Features
#1. Easy control
Preheating oven manufacturers today focus on better control of the machine, easy manipulation of the temperature, the movement of the product and the application of heat.
Today we have an advanced human-machine interface with programmable controllers that are meant to make the process user-friendly. It also helps in machine diagnostics.
The oven can be programmed in advance for desired results and monitored at all times to supervise the process.
It can be manipulated at any given time to change the temperature, move objects, change heating patterns or retrieve before time. Control is one of the essential factors in a preheating oven.
#2. Corrosion resistance
The presence of high temperature and steam can make for an extremely high corrosive atmosphere. These two together create an atmosphere that will start rusting most metals.
The most common material used in building ovens is aluminium steel, stainless steel or nickel alloy because of their ability to withstand high temperatures and corrosion.
There is also heavy insulation within to protect the body as much as possible.
#3. High efficacy fuel
Whatever heating source we use, it has to be extremely efficient. We need something that is both cost-effective and functional at the same time.
Whether we use fuel or electricity, we have to see which source works best for the oven size and better control.
#4. Easy access
For better control, we need access to process and oven areas.
Preheating is just the beginning of the process, and we need ready access to ensure that we can stop a process from continuing or controlling the product within.
Sometimes we may need to move the product to ensure even heating across the surface. All this needs easy access inside the oven.
#5. Efficient heating process
There are, of course, many factors that determine this vital function.
Custom programming and airflow management are two of the most critical factors for a Preheating oven manufacturer.
Every design aspect is critical, from the oven fan to the ductwork. These components affect heat regulation, ultimately affecting the economy of operation.
These are some of the features you must ensure in a good preheating oven.
