Spray dryer machine

· Feeder

The feeder is the introductory point for your material. It can either be vertical or cylindrical.

You have to control the quantity of what you allow into the feeder to facilitate the quality of your output.

· Control Panel

A control panel is a secure place within the dryer from where you can control its performance.

It consists of knobs and controls that help in adjusting the parameters for the machine’s effective functioning.

It is from here that you can control the speed, quantity, and size of the particles.

The power switch is also here.

· Heating Unit

The function of this part is to heat air or inert gas.

The heated air or inert gas is responsible for particle droplet formation.

The heating unit is available in two types.

That is a direct heating unit and a heat exchanger.

Several factors make a heat exchanger the better option compared to direct heating.

For instance, a heat exchanger allows for there is minimal heat loss during the heating process.

This helps in reducing the cost of heating.

The heated air flowing out of the heating chamber heats the cold air flowing into the heating chamber.

The use of a heat chamber also reduces environmental waste by allowing for heat recycling.

There are factors you need to consider when using a heat exchanger unit.

They include the thermal and physical properties of the air you are using and its temperature.

· Nozzles

It is from the nozzles that the hot air flows during the drying process.

The drying process takes place in the atomization unit.

The arrangement of the nozzles in the atomization unit is such that it allows for the hot air to spray on every part of your product.

This allows your work to dry uniformly.

The different types of nozzles available give the difference in terms of your powder particles’ size and properties.

· Drying Unit

The drying unit is the location of the nozzles.

The activity that takes place here includes dry spraying your particles.

The nozzles’ arrangements are in such a way that spraying takes place in every part of your particles.

The essence of the drying process is to remove water present in your particles resulting in tiny droplets.

· Outlets and Inlets

There are several outlet and inlet points in your small spray dryer with different functions.

Inlets are the introductory points of your dryer.

For example, you can have one that allows air to flow into the heating chamber.

The outlets are the exiting points of your dryer.

They allow for fluid and powder particles to flow from your dryer.

For instance, you can have an outlet that removes the heated air from the drying chamber to the atmosphere.

You can also have an outlet that removes the fine powder from the dryer.

· Atomization Unit

This is the point where the conversion of a tiny droplet into fine powder takes place.

This is by heating the droplets through the passing of hot air.

The efficiency of the atomization depends on the inlet dimensions and the number of nozzles.

A tangential shape for the inlet maximizes the hot air flowing, thus producing perfect powder particles

Which Nozzles can you use on a Small Spray Dryer?

The nozzles which are available for use on your small spray dryer are:

Nozzle for spray dryer

Nozzle for spray dryer

· Rotating Disk Nozzles

This type of nozzle has disks that rotate during the atomization process.

However, your solution should not have high viscosity.

This is important in regulating the atomization process.

The solution should be uniform for the powder particles to be uniform.

· Feeding the solution

This process takes place at the feeder.

You have to control the feeding rate of the solution to regulate the drying process.

· Atomization

The process of atomization involves solution separation. This results in water and tiny droplets.

You can use different atomizers to form other droplet properties.

However, the type of atomizer you select should form the perfect droplet for powder particles.

Standard atomizers include pressure nozzles, ultrasonic nozzles, and rotating disk nozzles.

· Drying

The process of drying involves passing hot air to the tiny droplets.

This takes place in the drying chamber when the hot air flows through the nozzles.

The flow is such that it allows for uniform drying of the particles.

You can have different nozzles for drying your particles.

The drying process’s efficiency depends on the air flow rate and the dimensions of the drying unit.

Therefore, you must consider subjecting the fluid to the optimum drying time to form the necessary particles.

· Nozzle Type

Nozzles facilitate the drying process of your particles.

They ensure maximum spraying of the particles during the drying process.

An effective nozzle should therefore spray the particle correctly to ensure maximum spraying of the particle.

You also have to ensure the nozzle operates for a given time to reduce the effect of over-drying

· Fluid Viscosity

The fluid viscosity affects the small droplet formation.

Forming large droplets involves their drying properties hence the final particle characteristics.

Having small droplets makes the particle properties to be tiny hence sticking on the walls.

The viscosity of your fluid should be one that forms the right particle size during the drying process.

· Temperature

Submitting your fluid to a higher temperature than the optimum temperature results in over-drying.

This affects the particle properties.

For best particle production, you need to subject the fluid to an optimum temperature.
