1) Large size, most of them cover an area of about 3 square meters;

2) Noisy, most of them have a noise level of above 100DB, causing a significant impact on the working environment of the laboratory;

3) High power consumption, most of them have a capacity of over 13KW;

4) Large sample volume, at least 2L of sample is required for each test, material preparation is troublesome.

In recent years, airflow spray dryer have become more and more widely used in laboratory because of its small size, low noise, low power consumption, and ease of use.

2. How a spray dryer works?

1) How centrifugal spray dryer works?

Liquid material is pushed by a peristaltic pump to a high-speed rotating atomizing disk, due to the centrifugal effect, a film of the liquid is formed and moves to the edge of the disk, where the liquid atomizes into small droplets and rapidly dries into powder in heated air flow in 3-5s.

2) How a pressure spray dryer works?

Liquid material is pushed into the spray dryer by a pressure up to 2-20MPa where it atomizes into small droplets. Such droplets have a big surface-to-volume ratio and can be dried in heated air flow in 10-30s. Most of the particles are collected through the discharge slot at the bottom of the tower, and the finer particles are separated from the exhaust air with a cyclone separator and collected with a collection bottle at the lower end of the cyclone separator as fine powder products.

3) How an airflow spray dryer works?

Liquid material is pushed by a peristaltic pump into a dual-flow atomizing nozzle, and is atomized under the action of compressed air. The atomized droplets are dried within 1-2 seconds in heated air flow. The powder particles are taken down and separated from the air flow by a cyclone separator and collected with a collection bottle, while the exhaust air is expelled or recycled.

3. The advantages and disadvantages of lab spray dryer and vacuum freeze dryers

Both spray dryer and vacuum freeze dryers are widely used in laboratories, and both have their specific advantages – spray dryer are fast, use less power, and can adapt to a wide range of material concentration; while vacuum freeze dryers impart higher solubility to the products, and can meet the strict conditions required for some heat-sensitive materials.

7. Which lab spray dryer is best for you?

7.1 Materials with high sugar content, such as Chinese herbal medicine extract or fruit and vegetable powder;

For these materials, our low-temperature spray dryer, such as YC-1800 and YC-018, may be the choice.

Sugar may melt and become very viscous at high temperature, so material with high sugar content may stick to the wall of the drying room when heated. To solve this problem, our low-temperature spray dryer apply some level of vacuum to assist drying, so that the inlet air temperature can be reduced to 105°C. At this temperature, the sugar in the material will not melt and will not stick to the wall.

7.2 Heat-sensitive materials, such as enzyme preparations, probiotics, heat-labile polymers, etc.;

For these materials, our vacuum spray dryer may be the choice, which are available in three specifications: 500ML/H, 1500ML/H, 3000ML/H.

These materials may experience chemical or biological changes at high temperature, and our vacuum spray dryer can operate with an inlet air temperature of 50 ° C to prevent these changes.

7.3 Materials in organic solvent;

Due to the flammable and explosible nature of organic solvents, a nitrogen cycle system(inert loop system) and a solvent recovery system are required to avoid explosion during the drying process. Our closed-cycle spray dryer, equipped with inert gas circulation system, are well suited for such materials, and are available in 500ML/H, 1500ML/H, 3000ML/H and 5000ML/H capacities.

7.4 Materials that should form large particles after drying, such as catalysts, ceramics, etc.;

Catalysts and ceramics sometimes need to be larger particles with a size of 50-80 microns for better performance – many catalysts must be over 50 microns for better catalytic effect and ceramic tablets need particles with a size of 50-80 microns for better molding. However, the average particle size of spray-drying products are often 1-25 microns. Our YC-018 laboratory-scale and YC-019 pilot-scale spray dryer can produce 50-100-micron particles, which meet the requirements of ceramics and catalysts.

7.5 Materials that need granulation or coating after drying;

For some materials, the desired particle size can hardly be achieved simply by drying, so you need further granulation and coating processes. Our YC-1000 spray granulator achieves all three functions seamlessly.

Which Types of Lab Spray Dryers do you have?

There are different ways you can classify your lab spray dryer.

That is, by the flow type, the stage numbers and the cycle type.

Organic spray dryer

· Co-current Lab Spray Dryer

In this type of dryer, the flow of the particles and the hot air flows in the same direction.

The spray evaporation rate in this dryer is high.

Vaporizing water preset reduces the high temperature of the drying air.

It is an ideal method for drying heat sensitive products since the heat does not come into direct contact with the product.

· Counter-current Laboratory Spray Dryer

This type of dryer involves the introduction of the air and spray in opposite ends of your dryer.

The atomizer is at the top of your dryer while the air flowing through is at the bottom.

This type of dryer offers rapid evaporation of your product due to its high energy efficiency compared to co-current type.

It is not, however, not the best method to use for heat sensitive products.

This is because the dry particles get in contact with the hot air.

· Mixed Current Laboratory Spray Dryer

This type consists of both counter-current and co-current flow.

In this type of flow, air flows from the top while the atomization process takes place at the bottom.

The drying process involves exposing the dry particles to hot air.

This type of lab spray dryer is not ideal for products that are heat sensitive.

Another way of classifying these dryers is by checking on the stage numbers.

Here you can have a single or multiple stage dryer.

A single-stage is a cost-effective and straightforward method of spray drying your products.

This type reduces the moisture content on your product by between 2-5%.

A multiple-stage la spray dryer is relatively expensive compared to the single-stage one.

However, it reduces the moisture content of your product by between 5 and 10%.

This type lets you use a low temperature for the drying process.

You can also have different types of lab spray dryers based on the cyclone type.

That is, you can have either closed or open cyclone lab spray dryers.

In an open cyclone type, the hot air flowing out of the drying chamber goes through a cleaning process before releasing into the environment.

In a closed cyclone, hot air goes through a treatment and drying process before recycling it into the machine.

A closed cyclone dryer is an energy-efficient type of dryer since it helps in reducing your overall energy bills.

What are the Components of Lab Spray Dryer?

A practical lab spray drying equipment has the following components:

Based on the flow type, you have the following types of lab spray dryer:

 Parts of spray drying machine

· Feeder

This is the top part of your lab spray dryer.

It takes various shapes depending on the design of your dryer, that is, cylindrical, square or triangle.

It is here that you place your product for it to flow through the drying machine.

It is crucial to control the rate of feeding your product into the system.

This ensures there is uniformity in the particle droplet formation.

· Control Panel

This consists of an easy to operate interface where one can control the activities of the machine.

It consists of buttons and switches that you press and allow the system to function.

It is from this point that you can control the airflow and particle speed.

· Heating Unit

The heating unit is responsible for heating the air or inert gas that facilitate in the particle droplet formation.

There are two types of heating unit that you can have for your machine.

That is a direct heating unit, where the heating unit heats the inert gas or air.

The other type involves heating air or inert gas through the use of a heat exchanger.

The second method involves checking on different parameters.

Such parameters include temperature, physical and thermal properties of air.

You also have to consider the air flowing through the hating section.

· Nozzles

The function of the nozzles is to facilitate the flow of the solution and the hot air either into the drying chamber or atomization unit.

There are different types of nozzles available for your drying machine, depending on your specifications.

· Drying Chamber

This is where spray drying takes place the aim of spray drying s to reduce our solution into tiny particle droplets.

It consists of several nozzles along its walls which facilitate the drying proceed.

Spray drying involves removing the water content of your solution to form tiny water droplets.

· Inlets and Outlets

Inlets are essential in allowing air or inert gas to flow into the system.

The inlets are usually at the top of the same level as your drying chamber.

The outlet allows for the flow of the hot air out from the drying unit.

This outlet is generally at the bottom of the evaporating unit.

There is also another outlet where the tiny droplets flow from the drying unit.

This outlet is also at the bottom of your drying chamber.

· Recovery Unit

The atomization unit is where the separation of tiny particles from hot air takes place.

Various parameters influence the efficiency of the separation process.

Such factors include the inlet design, cyclone dimension and number.

The shape of the hot air inlet here is usually wrap-around and tangential.

This shape enhances the volume of air flowing into this unit which increases the efficiency of the machine.

· Heat Exchange System

This is an optional component of your lab scale spray dryer.

It aims at reducing the cost of heating air or inert gas flowing into the system.

It does this by removing heat from the hot air exiting the system before releasing the air into the atmosphere.

The heat exchange system also helps in reducing environmental waste by cooling the air.

Which Type of Feeder can you use on Lab Scale Spray Dryer?

You can use a conical or horizontal type of feeder in a lab-scale spray dryer.

How does Spray Drying Process compare to Other Drying Techniques in Laboratory?

Spray drying is an ideal option for drying fluid products or solutions.

Other drying techniques such as freeze-drying are suitable for drying already manufactured products.

Lab freeze dryer

Spray drying is a cost-effective method of drying your products compared to other drying techniques.

It is for these reasons that are increasingly becoming a standard method of trying different products.

However, the use of a spray dryer is limited due to the type of product it can work with and its bulkiness.

It is heavy and large, which requires ample installation space.

How does Lab Spray Dryer Work?

The working principle of your lab spray dryer involves a series of steps right from the start to the finishing point.

These steps are:

· Feed Preparation

This step involves preparing the products that you will place on the feeder.

Such products are usually in a semi-liquid state.

The main challenge you experience here is the addition of little water as you stir the product to dissolve entirely.

It is essential for the mixture not to be vicious.

The highly viscous product makes it hard for atomization to take place.

You also have to ensure the viscosity of the mixture is uniform.

Mixture uniformity ensures uniformity in the droplet sizes.

· Atomization

Atomization is the separation of water from the tiny droplets.

Different types of atomizers exist for your selection.

However, each of these atomizers disperses uniform droplet sizes during the process.

The drying rate of a given particle squared is proportional its radius.

You can control the efficiency of the drying process by controlling certain variables.

These include; dryer dimension and the airflow rate.

The particle size should be reasonable to avoid drying problems.

That is, tiny particles may over dry hence affecting their performance.

Large particles don’t dry properly hence reducing tend to stick on the walls.

This reduces the total output of your product.

The different types of atomizers available in the market for your selection include.

They include ultrasonic, pressure nozzle and rotating disks.

Each of these nozzles uses different principles to operate.

For instance, rotating disk work by introducing the feed into the centre of rapid rotating disks.

These disks consist of vanes which help in directing the flow of the feeds.

Liquid flows from the edges of the disks breaking into droplets.

Rotating disks are best for use if your feed consists of entrained solids.

This is because it aims at reducing water contents.

The use of rotating disks is rare due to their high cost compared to the other types of nozzles.

Also, the functioning of a pneumatic nozzle involves mixing inert gas and the liquid feed.

This facilitates the formation of the droplets.  These nozzles are complex compared to the other nozzles.

They also have a frequency of plugging, which slows down the functioning of the dryer.

Pressure nozzle consists of tiny orifices where streams of feed flow breaking into droplets.

These nozzles are relatively cheaper though they tend to plug.

The plug has the effect of increasing back pressure, thereby destroying the flow pattern of the particles.

Ultrasonic nozzle breaks liquid stream using rapid vibration into tiny droplets.

You can have multiple nozzles in one dryer depending on its capacity.

· Heating Air

The next step involves heating either an inert gas or air.

This is either through combustion or the use of either electricity or steam.

The use of inert gas is preferred if the solvent is not water and is flammable.

You may introduce the hot air or gas concurrently with your liquid concentrate or counter currently depending on the design of your dryer.

The critical consideration here is to minimize the particles from hitting and sticking on the walls.

Such affects product quality.

What Affects the Efficiency of Laboratory Spray Dryer?

Several factors that affect the efficiency of your laboratory spray dryer.

Common ones include the volume of hot air flowing through the drying unit, the size and design of the nozzle.

Other factors include the duration of heat exposure and product concentration.

Which Raw Materials are suitable for Spray Drying Process?

The effect of altering the nozzle size is that it affects the particle size of your product.

This can lead to sticking of the particles, or the particles may not dry well

How do you Troubleshoot Lab Spray Dryer?

Troubleshooting your ab spray dryer depends on the type of problem it is experiencing.

Among the ways, you may troubleshoot your lab spray dryer based on given issues include:

· Low Powder Quality and Inconsistency

The leading cause of having a low powder quality and inconsistency is product buildup.

The product buildup is due to the design of your nozzle.

The effect of product builds up is over time the particles deposit on the sides affecting the quality of your powder.

To solve this, you need to use a flat cap design that offers a low outer face design hence minimizing product buildup.

· Misalignment of Wear Parts

Misalignments of wear parts cause inconsistency in the powder formation resulting in low-quality powder.

Solving this involves aligning all the wear parts to be in perfect shape to perform effectively.

· Low Productivity

The main problem of low productivity is nozzle bearding which is as a result of dryer configuration.

Alternatively, it may be due to using wide spray angles or nozzle profile.

Low productivity increases the frequency of your cleaning schedule due to the amount of dirt deposited.

You also have to stop production from cleaning the machine effectively, thus reducing the output.

The best way of solving this problem is by using a flat cap profile.

This offers a low outer face design which reduces bearding.

· Hygiene Standards

Proper hygiene is essential, especially for related human products.

Several factors reduce the cleanliness of your machine.

For instance, the particle deposits lead to a buildup hence contaminating the powder.

The reasons for such is using the wrong nozzle design.

You need to solve this by regularly carrying out a maintenance schedule and checking if there is any particle leakage.

You may also have to replace the design of your nozzle and use a flat structure.

A flat design reduces particle buildup, which reduces the amount of dirt deposited on the walls.

· High Production Cost

High production cost may be as a result of having an improper connection.

It may also be due to the use of wrong spare parts.

Another cause of high production cost is If your machine is outdated.

You can solve this problem in various ways.
