What are Organic Solvents?
An organic solvent is a carbon-based substance.
This substance can dissolve or disperse one or more other substances.
You can have organic solvents that can be:
- Reproductive Hazard
Organic solvents that are reproductive hazards include methyl chloride, 2-ethoxyethanol, and 2-methoxyethano.
Examples of carcinogenic solvents include trichloroethylene, carbon tetrachloride, and benzene.
Neurotoxin organic solvents include toluene, n-hexane, and tetrachloroethylene.
Some of the classes of chemicals you can use as organic solvents include:
- Nitrate or chlorine hydrocarbons
- Aliphatic hydrocarbons
- Aromatic hydrocarbons
What is an Organic Solvent Spray Dryer?
An organic solvent spray dryer is a machine that sprays and dries organic solvent solutions.
This means the machine assists you do the spraying and drying of substances that are not water-soluble.
Why do you need to Use an Organic Solvent Spray Dryer?
An organic solvent spray dryer is an essential machine in many fields.
You need an organic solvent spray dryer to spray and dry materials that can easily dissolve in organic substances.
The machine will meet your production needs promptly.
The machine is also safe for spraying and drying organic solvents.
What are the Physical Properties of an Organic Solvent?
There are many organic solvents available that you can use on an organic solvent spray drying machine.
Each organic solvent has different physical properties to them.
We are going to generalize the physical properties of organic solvents.
Let’s look at the three physical properties you will come into when handling organic solvents:
· Boiling Point
Organic solvents have a low boiling point.
This low boiling point makes sense when you talk about the volatility of organic solvents.
A low boiling point means the organic solvent evaporates rapidly.
This is an important relationship to consider when checking the physical properties.
The physical property of volatility points out to the capability or the tendency for an organic solvent to vaporize.
Vaporization is the ability of an organic solvent to turn from a liquid state to a gaseous state.
When an organic solvent vaporizes, it mostly releases an offensive smell.
An example is when you open a can of open paint and get hit on the face by the smell.
· Color and Size
Even though organic solvents have a distinct smell, they are known to be a colorless and clear liquid.
Organic solvents also have a low molecular weight [g/mol].
What are the Safety Features of an Organic Solvent Spray Dryer?
Organic spray dryer machine
Organic solvents are flammable, toxic, and explosive.
This makes organic solvents unsafe and dangerous to your health.
This is most evident when you use it in an open working environment.
It is therefore important to operate an organic solvent spray dryer in an enclosed working environment.
Working in an enclosed environment minimizes any health and safety issues that may arise.
Also, you will use an inert gas such as nitrogen or argon to replace the air that a common spray dryer uses.
An inert gas handles the issue of flammability of organic solvents.
Besides, you can recycle the nitrogen or other inert gas.
You can also reuse the inert gas after condensation.
This makes an organic solvent spray dryer secure, environmentally friendly as well as economical.
Can you use an Organic Solvent Spray Dryer for Other Solvents?
Yes, you can use an organic solvent spray dryer for many solvents.
This is because it has a broad range of inlet air temperature.
This temperature can range from 60°C to 280°C.
What are the Parts of an Organic Solvent Spray Dryer?
Parts of spray dryer
An organic solvent spray dryer has many components that work together.
All these components are essential to produce the best quality final product.
Knowing how these parts operate is also an important factor to consider when you operate an organic solvent spray dryer.
The parts of an organic solvent spray dryer include:
· Feed pump
The feed pump directs the organic solvent solution into the atomizer.
Besides, the material that is to undergo spraying and drying has to be in a liquid form.
· Atomizer or Spray Nozzles
Normally, the atomizer will make the evaporation and drying process to be more effective.
Also, the atomizer changes the liquid into small droplets.
The atomizer applies pressure on the bulk liquid for the conversion to happen.
Different atomizers can change the bulk liquid into droplets.
The kind of atomizer you choose will affect the size of the droplets.
· Heating System
The heating system does the job of heating the air that will dry the liquid droplets.
It has to be of a certain temperature before it starts the drying process.
The heating system can have two designs:
- Direct method
The air that you are using to dry the tiny droplets is in direct contact with the heating source.
A flame can be the source of heat.
- Indirect method
In an indirect method, you will not heat the air directly with the heat exchanger.
· Drying Chamber
The drying chamber is the house that all the drying takes place.
You will remove moisture in the drying chamber when the hot air mixes with the tiny droplets.
The air and liquid droplet mixture happen here.
The length of the drying chamber affects the residence time of the mixture you are dying.
Some of the factors that influence the size of the drying chamber include:
- The kind of atomizer or spray nozzle
- The temperature of the inlet air
- The feed rate
- The distribution type of the feed
· Powder Recovery System
The powder recovery system collects all the dry powder.
· Process Control System
This is a system from which you can easily change the parameters of the drying process.
It has a programmable logic controller [PLC] with a touch screen to easily input various commands.
How does an Organic Solvent Spray Dryer Work?
An organic solvent spray dryer works by atomizing organic solvents.
The following are the steps on how an organic solvent spray dryer works:
· Wet Stage
The wet stage is the very first step you should take when working with an organic solvent spray dryer.
All the materials that will undergo drying are in a liquid form.
The liquid solution makes it possible for atomization to happen effectively.
The various steps in the wet stage include:
- Dissolution or formulation
This is the step where you will mix the raw material with the organic solvent to form a liquid solution.
- Evaporation or concentration
In this step, you will increase the solid that produces a superior yield.
Heating assists in taking care of the increase in viscosity that happens due to concentration.
The organic solvent solution is known as slurry.
In the pumping stage, you will use high pressure to pump the organic solvent solution.
· Atomization Stage
Atomization makes it possible for drying to take place rapidly as the bulk liquid is now in small droplets.
Atomization will increase the surface area of the liquid making it easy for moisture to evaporate from the particles.
The spray nozzles are responsible for atomization.
The material and flow rate will assist you in choosing the best nozzle design from the many available in the market.
Examples of the types of atomization nozzles include:
- Rotary nozzle
- Pressure nozzle
- Two-fluid nozzle
· Contact Stage
When the droplets get in contact with the hot dry air, drying takes place.
The air that you will use to dry the fine droplets has to have a high temperature before this contact begins.
Hot air makes it easy for moisture in the particles to vaporize rapidly.
The hot air gets into the drying chamber when it is hot and dry.
On exiting the drying chamber, it is humid and has a low temperature.
The hot air can enter the drying chamber in two ways:
This happens when the hot air enters the drying chamber from the top.
This means that the fine droplets and hot air come from the same direction.
Most spray dryers use the co-current drying technique.
The co-current drying technique prevents the powder from overheating.
- Counter Currently
This happens when the hot air enters the drying chamber from the bottom.
This means that the fine droplets and hot air come from opposing directions.
· Drying Stage
Drying of the fine droplets happens in the drying chamber.
Hot air removes moisture from the particles as there is a heat exchange process.
The drying process can occur in three ways:
- Bubble Formation
The temperature of the particles increases during the falling rate.
The organic solvent in the particle will vaporize when the temperature gets higher than its boiling point.
A bubble will form once the organic solvent vaporizes.
- Falling Rate
The characteristic of the organic solvent in the solid particle influences the drying process.
Diffusion influences this drying process.
- Constant Drying rate
The organic solvent will saturate the particles in this stage.
A lot of transfer happens quickly when the surface of the particle is larger.
· Collection Stage
In the collection stage, you will collect all the dry powder.
Cyclones help to separate the drying air from the dry particles.
Cyclones with filters increase the efficiency of the separation of these two.
The particles separate from the air once it enters the cyclone.
Also, the dry powder gathers at the bottom of the organic solvent spray dryer.
What is the Capacity of an Organic Solvent Spray Dryer?
An organic solvent spray dryer has an evaporating capacity of different values.
On average, the evaporating capacity can range from 500 ml/h to 3500 ml/h.
