Parts of spray dryer fordetergent powder

Parts of spray dryer for detergent powder

A spray dryer for detergent powder has different components which work harmoniously to ensure quality products. The main parts of this machine are:

Air Filter

The purpose of this component is to prevent contamination of the detergent powder. This is by filtering dirt and other combustible material which are present in the air.

Due to its function, you have to replace this part for quality filtering frequently.

Intake Fan

The intake fan work is to drive the outside air into the spray dryer. It is usually on below the air filter.

The intake fan pushes the air with pressure into the dryer for its functioning.

Heat Source

The hating source is responsible for heating the air that is flowing into the spray dryer.  This can either be directly or indirectly.

Direct heating involves air passing through the heat source. Indirect heating involves fluid heating fluid such as water which then heats the air.

Feed Source

The feed source is the entry point for the detergent that you want to spray dry. In some models, you heat the feed source to reduce the viscosity of your detergent.


This is the point where the transformation of the detergent takes place into tiny droplets. Then, the atomization process takes place through passing hot air, which heats the droplets.

For the atomization process to work efficiently, you have to consider the number and dimensions of the inlet.

Drying Chamber

The function of this chamber is to dry the tiny droplet to form the required powder content. Thus, the main activity that takes place here is dry spraying which ensures quality powder production.

Control Panel

The control panel is a safe extension on the exterior of your machine that consists of knobs and buttons. It is from here that you adjust the working parameters of your machine.


The number of nozzles varies depending on the design of your spray dryer for a detergent powder machine. They are the channels through which hot air flows during the atomization process.

Different types of nozzles offer different drying powder particles.

How Does Detergent Powder Spray Dryer Work?

The working of a detergent powder spray dryer depends on its various parts. The starting point is the feeding source where you introduce your products.

The product should be in liquid form and of high viscosity, which facilitates the atomization process. The solution flows to the atomization chamber.

The atomization chamber is where there is the transformation of the solution into tiny droplets. Different atomizers offer different droplets resulting in different powder products.

Standard atomizers that you can use are ultrasonic nozzles, pressure nozzles, and rotating disk nozzles.

After atomization, the next step is to dry the droplets in the drying chamber through heating.

Heating involves the passing of hot air on the droplets at a given temperature. There are two ways of achieving this directly or indirectly.

Direct heating involves passing hot air or an inert gas over the droplets. However, this is not a common practice due to the possibility of contaminating your product.

In indirect heating, heat passes through a heat exchanger system which in turn heats the droplets. It is an ideal method since it allows for heat recycling which reduces overall cost.

There is also no contamination of your product since the product does not come into contact with the hot air.

The pressure nozzle and fluid nozzle can originate in different points of the atomization chamber. Therefore, proper production depends on the speed of the nozzles and solution flow.

Counter-current Mode

In counter-current mode, the functioning of the two-fluid nozzle and pressure nozzle is on the opposite ends. This results in fine powder formation.

It is an ideal method for drying detergents that are heat sensitive. However, you have to regulate the pressure and the fluid nozzle to achieve the desired results.

Co-current Mode

In co-current mode, both the working of the two-fluid and pressure nozzle is in the same direction. This forms fine granules of detergent powder.

For proper functioning of this flow, you have to check on the speed of the fluid flow and pressure of the pressure nozzle. It is an ideal method to use if you want fine, coarse particles as the end products.

It is also the best option to use when you are producing heat-sensitive detergent.

How Does the Atomizer Type Impact the Particle Size in Spray Dryer for Detergent Powder?

The different atomizers offer different particle sizes depending on factors affecting their particle production.

For instance, two-fluid nozzles often result in coarse particle production.

Particle production under a pressure nozzle is usually coarse and has a narrow distribution. On the other hand, a rotary atomizer produces fine particles which are free-flowing.

However, the manufacturing of these particles depends on the adjusting factors of the individual atomizer.
