How does a Nano Spray Dryer Work?

A nano spray dryer and the conventional spray dryer dries powder using similar concepts.

However, a nano spray dryer has instruments such as:

  • The cylindrical drying chamber.
  • The atomizer that produces the spray.
  • The permeable metal form which produces laminar flow in the drying of the gas.
  • The electrostatic particle collector.

Here is how a nano spray dryer works:

i. Material Wetting Process

The wet process is the very first step when using a nano spray dryer.

You will mix up all the materials that you are to feed in the machine.

It has to be in liquid form so that you can extract the powder from the liquid solution.

ii. Atomization Process

You will then direct the liquid solution to the spray head.

A piezoelectric actuator will generate a fine spray of droplets from the liquid solution.

You will use a vibrating mesh in the nano spray dryer.

The mesh system contains small caps that have an exact arrangement of micrometer-sized holes.

Stainless steel is the material that makes up the small caps.

You can control the vibration frequency of the cap to produce moderate to high droplet size.

The piezoelectric actuator vibrates between 60–140 kHz.

This high frequency of vibration produces millions of droplets every second.

The distribution of the droplets is in a homogeneous size.

The size of the droplets depends on:

  1. The viscosity of the solution.
  2. The surface tension.
  3. The size of the holes in the stainless-steel membrane.

For instance, a spray mesh with 4 µm will produce droplets in the range of 3–8 µm.

The size of the mesh is directly related to the size of the droplets.

This in turn affects the particle size and physiochemical properties of the final product.

iii. Contact Between the Air and the Liquid

The particles now enter the drying chamber from the top.

The drying gas will also enter from the top of the cylindrical drying chamber.

This is known as co-current flow since both the drying gas and liquid enter from the same direction.

iv. The Drying Process

The heating system in a nano spray dryer will produce laminar flow.

Laminar flow happens when the air passes via a compact porous metal foam.

Laminar flow is unique to nano spray dryers since conventional spray dryers use turbulent flow.

The design of the heating system provides hot gas entry flow in the renowned Reynold number regime (Re < 2300).

When using a laminar flow, the particles move in a unidirectional manner.

This limits the path of travel which minimizes the contact of the droplets with the wall of the dryer.

Besides, since the drying process happens close to the spray head, the heating process happens early.

This will reduce the residence time and developing the conservation of heat-sensitive items.

Hot air will dry the particles while directing them to the collector at the bottom of the drying chamber.

The length of the cylinder can affect the drying of different substances.

The length will affect the residence time.

For fine sprays of tiny droplets, a short drying chamber is recommended.

This is because the residence time is low (1–4 seconds) and the droplets would reach a complete drying state.

In contrast, large particles require a long cylinder to increase the residence time for them to dry completely.

For dry solid particles, a short drying cylinder is good for achieving fine particle sizes.

On the other hand, a long drying chamber is good for achieving large particle sizes.

v. Collection Process

A nano spray dryer uses an electrostatic particle collector to achieve a high collection performance.

The machine uses a cylindrical anode, two electrodes, together with a grounded cathode.

All this makes up the electrostatic system.

The machine applies an electrostatic field in the drying process and applies a high voltage amidst the electrodes.

This will quicken the particles that have a negative charge and attract them to the surface of the electrode.

Once they discharge, the particles will separate from the wall.

The particles then fall inside the electrostatic particle collector where you will collect them.

What Heating System does a Nano Spray Dryer use?

Nano spray dryer

 Nano spray dryer

A new heating system produces particles in a nano spray dryer.

In a nano spray dryer, heat flow is laminar and nor turbulent as is in conventional spray dryers.

The laminar flow has an advantage in that the particles fall straight down upon leaving the spray head.

This makes it possible for the particles not to stick to the glass wall.

A nano spray dryer produces laminar flow by pressing air via a porous metal foam.

What is the Evaporating Capacity of a Nano Spray Dryer?

A nano spray dryer has an evaporating capacity of 1.5 liters per hour when you use water.

However, you can use a small quantity of solution to perform an experiment.

You can use a small capacity of 30ML to conduct an experiment.

This means you can use a nano spray dryer for large and small samples depending on your needs.

This variation reduces wastages when doing experiments as you only use what you need.
