What is a Benchtop Spray Dryer?
A benchtop spray dryer is equipment that produces dry powder from a liquid.
It quickly uses hot gas to dry it.
The mist is sprayed into a chamber that has hot air.
After being sprayed into the hot air chamber, it falls to the bottom in the form of dry powder.
Spray drying process
Benchtop spray dryer
What are the Components of a Benchtop Spray Dryer?
A benchtop spray drier has several components that all work in the spray drying process.
Some of the components in the benchtop spray dryer are:
Schematic of spray drying machine
Atomizer or Spray Nozzles
The atomizer does the work of turning the liquid in the chamber into small droplets of liquid.
LED Screen
You will control and monitor the working of the benchtop spray dryer through the LED screen.
The screen displays the necessary parameters like air inlet, temperature, airspeed, air volume, and needle frequency.
A Reliable Sealing
The sealing is vital for the spray drying process.
It forms an airtight seal, meaning you have a suitable environment for the whole spray drying process.
The Power Switches
With the power switches, you can quickly turn on and off the benchtop spray dryer.
Drying Chamber
The drying chamber is made of borosilicate glass.
Borosilicate glass is a high-quality glass that is easy to clean.
Since the glass is transparent, you can easily monitor the whole spray drying process.
Collecting Tube
The collecting tube directs the final product to the collecting chamber or bottles.
Collecting Bottles
The collecting bottles are where the final product is collected and stored.
Peristaltic Pump
The peristaltic pump is used to pump the fluids that are then to be dried.
Air Dispenser
It directs air into the benchtop dryer system.
Air Heater
You can easily control it as a suitable temperature depending on the material you’re drying.
It is the hot air that helps in the drying process.
How does a Benchtop Spray Dryer Work?
A benchtop spray dryer works by drying fine mist into powder.
The following are steps on how a benchtop spray dryer works.
The Wet Process
Before you start the process of spray drying, the material you want to dry should be in liquid form.
Here, you will condition the material that is to be spray dried.
The purpose is to make the spray drying a success and also to optimize the yield.
The wet process involves the following steps:
i. Formulation
The formulation is also referred to as dissolution.
You’ll do this for raw materials that are not in liquid form.
The raw materials are dissolved to make it in liquid form.
After this, the dissolved material is ready for the next stage.
ii. Evaporation
Evaporation can also be referred to as concentration.
In this stage, you are increasing the total solid.
This will result in a better yield for the spray dryer.
iii. Heating
You will then heat the liquid.
Heating will counteract the increase of viscosity that is formed in the concentration stage.
iv. Pumping
After all the above steps, the liquid is then pumped at high pressure.
The pumping directs the liquid to the spray dryer.
Atomization
The liquid to be dried is atomized into tiny droplets.
By atomizing, you ensure that you have a fast-drying process of the liquid.
The humidity in the particles will dry at a rapid rate.
The atomizer is the nozzle or nozzles that will help in atomization.
There are different types of nozzles in the market that you can choose.
Also, the kind of nozzle you choose has to match the material and the flow rate of the liquid.
You will get the best outcome by using the right nozzle.
The types of nozzles available are pressure nozzle, two-fluid nozzle, and pressure nozzle.
Contact of Material to be Dried and Hot Air
The process of drying takes place as hot air gets into contact with the sprayed droplets.
The dry air takes up moisture.
You are to heat the air in the spray drying chamber before the sprayed droplets enter this chamber.
The dry air has low humidity at the inlet.
On the other hand, it has high humidity and low temperature at the outlet.
The hot, dry air can be pumped in two ways:
· Co-currently to the Product
Blowing hot air co-currently to the product means you are blowing it from the top of the tower.
· Counter-current to the Product
Blowing hot air as a counter-current, you are blowing it from the bottom of the tower.
Many applications prefer the counter-current process.
In contrast, co-current spray drying has an exciting appeal.
The exciting part is that the hot, dry air gets into contact with the first particles with the most significant humidity.
This means the particles are protected against overheating.
Drying
The drying process occurs in the spray drying chamber once the particles are inside it.
Moisture is removed sequentially with the help of the heat transfer between the air and the particles.
The drying process is done in three ways:
Constant Drying Rate
Here, the particles are saturated with liquid.
If the surface of the particle is large, the mass transfer happens quickly.
Falling Rate
The drying depends on the capability of the liquid held in the solid particles to diffuse and evaporate.
This process is controlled by diffusion.
Bubble Formation
During the falling rate, the temperature of the particles will increase.
If the temperature gets higher than the boiling point of the liquid in the particle, it may vaporize.
This, in turn, will create a bubble.
Solids Separation
You are then to collect the particles once they are thoroughly dried.
The separation is mostly done in cyclones.
Besides, the cyclone could be equipped with filters to increase their efficiency.
Furthermore, the powder is separated from the air once it is in the cyclone.
That is, once it is collected at the bottom of the benchtop spray drier.
What are the Types of Spray Nozzles a Benchtop Spray dryer uses?
A spray nozzle is equipment that is used to break apart liquid into a spray pattern.
A benchtop spray drier can use various types of nozzles.
Some of the nozzles that a benchtop spray drier can use include:
Spray dryer nozzle
Flat Fan Nozzle
To produce a line of spray, use a flat fan nozzle.
Flat fan nozzles come in two designs: standard shape and deflection orifice.
Misting Nozzle
To form a mist or fog that is finely atomized with no movement, use misting nozzles.
A homogenous fog is mainly directed by the surrounding airflow and not the nozzle.
The types of missing nozzles are small and impingement orifice.
Hollow Cone Nozzle
A hollow cone nozzle produces a solid circle of spray.
A spray pattern has the smallest drop sizes of all the spray patterns.
Some of the designs of the hollow cone nozzle include tangential whirls, spirals, and axial whirls.
Solid Stream Nozzle
The aim function of a solid stream nozzle is to deliver as much impact as possible.
Solid stream nozzles concentrate fluid into a dot of spray with a high impact.
The two designs for a solid stream nozzle include an enhanced laminar flow and a standard shaped orifice.
Full Cone Nozzle
Full cone nozzle will produce a solid circle of spray.
You can use this nozzle when you want to distribute the fluid over an area evenly.
The designs of a full cone nozzle are tangential whirls, spirals, and axial whirls.
Eductor Nozzle
You will use an educator nozzle to mix and agitate fluids.
Spillback Nozzle
You will use a spillback nozzle for a high turndown rate while maintaining the size and other spray qualities alike.
Can you use Benchtop Spray Dryer to Combine Ingredients?
Yes, you can combine ingredients on specific benchtop spray dryer designs.
When you combine these small particles, you will get a product that dissolves easily.
Generally, combining ingredients improve the quality of the final product.
The materials are chemically and nutritionally equal.
In addition to this, the combination of ingredients makes it have a larger surface area per volume.
With this in mind, it will tend to dissolve.
What is Atomization in a Benchtop Spray Dryer?
Atomization is an essential part of the benchtop spray dryer process.
In the atomization process, the liquid is fed and converted to small droplets using the nozzle or rotary atomizer.
The desired qualities of the final product, such as viscosity and particle size, are developed during this process.
The small droplets have a larger surface area.
Meaning the rate of evaporation of water is increased.
The droplets, through evaporation in the dryer chamber, become individual powder particles in the drying stage.
Spray dryer structure
What Principles does a Benchtop Spray Dryer Use?
The main principle of a benchtop spray dryer relies on removing water.
The quality of the final product depends a lot on how the water is removed.
Your starting point should be to determine moisture content in the product.
Then, the size and type of particles you need.
Remember, this will influence the type of atomizer you will use.
Another factor is the kind of dryer.
You need a large surface area for drying if you are using a tall form benchtop spray dryer.
The surface area affects how you will attain the specifications of the product.
Once you consider all these, there is a possibility that you will get the best products.
How does Benchtop Spray Dryer compare to Mini Spray Dryer?
A benchtop spray dryer is small in size and quiet.
Also, as the name suggests, a benchtop spray dryer is used on a tests bench.
Moreover, a benchtop spray dryer can use 20ml of sample to complete a test.
A mini spray dryer usually requires 1000ml of the sample in every experiment.
A mini spray dryer uses more power than a benchtop spray dryer.
With a low power consumption, a benchtop spray dryer saves energy.
A benchtop spray dryer mostly costs less than a mini spray dryer.
In short, these two types of spray drying machine are similar except for the size and uses.
What is the Importance of a Spray Analysis in a Benchtop Spray Dryer?
You are required to have specific know-how and skills when conducting a spray analysis in a benchtop spray dryer.
You can also hire a spray analysis services if you do not have such knowledge.
Having a benchtop spray dryer that is in good condition will give you a better output and reduce risks.
It is important to note that you should attain the right air to fluid balance.
Failure to achieve this balance, you will get a final product that is not consistent.
The inconsistency may be in the form of particle sizes, ingredient mixture, or moisture content.
You will see visible bands if you are using metallic material or a solid color.
In addition to this, over atomization results in a poor finish.
Knowing the spray pattern is crucial for you to get the correct output.
A common issue is incorrect to paint to air balancing.
This results in a substandard fan shape and material discharge.
Spray analysis in a benchtop spray dryer helps you realize if there is an issue that is happening while spraying.
Furthermore, spray analysis assists you to examine other things that may affect the quality of the final output.
